LASP research associate Nick Schneider has been awarded NASA’s Exceptional Scientific Achievement Medal for his contributions to the success of NASA’s orbiting MAVEN mission now at Mars.
Schneider, also a University of Colorado Boulder professor of astrophysical and planetary sciences, is the lead scientist on the LASP-built Imaging Ultraviolet Spectrograph (IUVS) riding on NASA’s MAVEN spacecraft that arrived at Mars in 2014. LASP Associate Director for Science, Bruce Jakosky, is the principal investigator for the MAVEN mission.
NASA’s Exceptional Scientific Achievement Medal is given for individual efforts that have resulted in key scientific discoveries or contributions of fundamental importance in the field. Schneider was presented with the medal in a ceremony Oct. 31 at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
A team led by LASP scientists, engineers, and students has been selected to build a tiny orbiting satellite to study the evaporating atmospheres of gigantic “hot Jupiters”—distant gaseous planets orbiting scorchingly close to their parent stars.
To date more than 100 gas giants have been discovered orbiting very close to their parent stars, said LASP planetary scientist, Kevin France, principal investigator on the four-year, $3.3 million effort funded by NASA. France and his colleagues believe the new study of hot Jupiters—some of which are so close to parent stars they orbit them in a matter of days—will help planetary scientists better understand the evolution of our own solar system.
A solar instrument package designed and built by LASP, considered a key tool to help monitor the planet’s climate, has arrived at NASA’s Kennedy Space Center in Florida for a targeted November launch.
The instrument suite is called the Total and Spectral solar Irradiance Sensor (TSIS-1) and was built for NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The contract value to LASP is $90 million and includes the dual instrument suite and an associated ground system to manage TSIS mission operations.
NASA’s MAVEN mission to Mars led by LASP and the University of Colorado Boulder will hit a happy milestone on Saturday, June 17: 1,000 days of orbiting the Red Planet.
Since its launch in November 2013 and its orbit insertion in September 2014, the Mars Atmosphere and Volatile Evolution Mission (MAVEN) has been exploring the upper atmosphere of Mars, said LASP associate director and CU Boulder Professor Bruce Jakosky, principal investigator of the mission. MAVEN is bringing insight into how the sun stripped Mars of most of its atmosphere, turning a planet once possibly habitable to microbial life into a barren desert world.
Humans have long been shaping Earth’s landscape, but now scientists know we can shape our near-space environment as well. A certain type of communications—very low frequency, or VLF, radio communications—have been found to interact with particles in space, affecting how and where they move. At times, these interactions can create a barrier around Earth against natural high energy particle radiation in space. These results, part of a comprehensive paper on human-induced space weather, were recently published in Space Science Reviews.
“Our recent work with the LASP Van Allen Probes instruments has shown compelling evidence that the radiation belts are quite subject to human-made waves emanating from ground-based radio transmitters. Thus, humans have not only been affecting the oceans and atmosphere of Earth, but have also been affecting near-Earth space,” said Dan Baker, LASP director and co-author of the paper.
A LASP-built instrument that will provide unprecedented imaging of the Earth’s upper atmosphere has been successfully installed on the commercial satellite that will carry it into geostationary orbit some 22,000 miles above the Earth.
The Global-scale Observations of the Limb and Disk (GOLD) mission, led by the University of Central Florida (UCF) and built and operated by LASP, features a collaboration with satellite owner-operator SES Government Solutions (SES GS) to place an ultraviolet instrument as a hosted payload on a commercial satellite.
Toting an ultraviolet instrument designed and built by LASP, NASA’s Cassini spacecraft made the first of 22 dives between the rings of Saturn and the gaseous planet today, the beginning of the end for one of NASA’s most successful missions ever.
Launched in 1997 and pulling up at Saturn in 2004 for the first of hundreds of orbits through the Jovian system, the Cassini-Huygens mission has fostered scores of dazzling discoveries. These include in-depth studies that date and even weigh the astonishing rings; the discovery of methane lakes on the icy moon Titan; hot water plumes found squirting from the moon Enceladus; and closeup views of the bright auroras at the planet’s poles.
A NASA instrument that will study the upper atmosphere and the impact of space weather on Earth is a step closer on its journey into space.
The Global-scale Observations of the Limb and Disk (GOLD) mission, led by University of Central Florida (UCF) scientist Richard Eastes, is scheduled to launch in late 2017 from Florida. Earlier this month, the LASP-built instrument was shipped to Airbus Defence and Space in Toulouse, France, for integration on the SES-14 communications satellite, on which it will be launched into space.
LASP researchers have discovered an atmospheric escape route for hydrogen on Mars, a mechanism that may have played a significant role in the planet’s loss of liquid water.
The findings describe a process in which water molecules rise to the middle layers of the planet’s atmosphere during warmer seasons of the year and then break apart, triggering a large increase in the rate of hydrogen escape from the atmosphere to space in a span of just weeks.
University of Colorado Boulder students and LASP professionals will operate an upcoming NASA mission that will investigate the mysterious aspects of some of the most extreme and exotic astronomical objects like stellar and supermassive black holes, neutron stars and pulsars.
Objects such as black holes can heat surrounding gases to more than a million degrees, causing high-energy emissions in the X-ray portion of the electromagnetic spectrum. The high-energy X-ray radiation from this gas can be polarized, which causes it to vibrate in a particular direction.
The NASA Imaging X-ray Polarimetry Explorer (IXPE) mission will fly three space telescopes with cameras capable of measuring the polarization of cosmic X-rays, allowing astronomers to answer fundamental questions about such turbulent environments.
A multimillion dollar CU-Boulder/LASP instrument package expected to help scientists better understand potentially damaging space weather is now slated to launch aboard a National Oceanic and Atmospheric Administration satellite on Saturday, Nov. 19.
Designed and built at LASP, the instrument suite known as the Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) is the first of four identical packages that will fly on four NOAA weather satellites in the coming decade. EXIS will measure energy output from the sun that can affect satellite operations, telecommunications, GPS navigation and power grids on Earth as part of NOAA’s next-generation Geostationary Operational Environmental Satellites-R Series (GOES-R).
Today, the LASP-led MAVEN mission has completed one Mars year of science observations. One Mars year is just under two Earth years.
The Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft launched on Nov. 18, 2013, and went into orbit around Mars on Sept. 21, 2014. During its time at Mars, MAVEN has answered many questions about the Red Planet.
A bread loaf-sized satellite, designed and built by University of Colorado students, has been collecting data since its deployment from the International Space Station on May 16 and is providing observations of the sun at unprecedented wavelengths and resolution.
The Miniature X-ray Solar Spectrometer (MinXSS)—a 30cm x 10cm x 10 cm, 3-unit satellite—is the first ever science CubeSat launched for NASA’s Science Mission Directorate and has already met its minimum mission science criteria for data and observations.
Wearing latex gloves and focused expressions, a group of middle school students gathered around a large cardboard tube recently at the CU Boulder Engineering Center then carefully began wrapping it in fiberglass. All the while, an undergraduate with the CU Students for the Exploration and Development of Space (CU SEDS) organization explained how rockets are designed and built.
Soon, these same students will travel to southern Colorado to launch a rocket they helped assemble as part of a CU Junior Aerospace Engineering Camp. This camp, in particular, brought students to campus from Casa de la Esperanza, a housing community in Longmont for agricultural workers and their families.
A group of LASP scientists and students are anxiously awaiting the arrival of NASA’s Juno spacecraft at Jupiter July 4, a mission expected to reveal the hidden interior of the gas giant as well as keys to how our solar system formed.
Launched in 2011, the spacecraft is slated to orbit Jupiter’s poles 37 times roughly 3,000 miles (4,828 kilometers) above its cloud tops to better understand the origin and evolution of the largest planet in the solar system. Scientists hope to determine if Jupiter has a solid core, measure the planet’s magnetic fields, hunt for water vapor and observe the polar auroras.
Three planetary scientists from LASP and five University of Colorado Boulder (CU-Boulder) students are part of the Juno mission.
Satellites provide data daily on our own planet, our sun and the universe around us. The instruments on these spacecraft are constantly bombarded with solar particles and intense light, not to mention the normal wear and tear from operating in space.
If it were a car that’s a few years old, you would take it to the mechanic for a tune-up to make sure it continues running smoothly. However, with a spacecraft it’s not that easy. Thus, scientists may turn to calibration flights to make sure the instruments are kept up to snuff and providing validated data.
One such flight will be the Extreme UltraViolet (EUV) Variability Experiment, or EVE, from the University of Colorado, Boulder, to observe the sun from a NASA Black Brant IX sounding rocket at 3:02 p.m. EDT May 25 at the White Sands Missile Range in New Mexico.
The bread loaf-sized Miniature X-Ray Solar Spectrometer (MinXSS) CubeSat will be deployed from an airlock on the International Space Station (ISS) at 4 a.m. MDT on Monday, May 16, beginning its journey into space where it will study emissions from the sun that can affect ground-based communications systems.
The NASA-funded MinXSS, designed, built, and operated by University of Colorado Boulder students and faculty at LASP and CU-Boulder’s Aerospace Engineering Sciences Department (AES), will operate in Earth’s orbit for up to 12 months. The CubeSat will be deployed from the ISS via a special deployer designed by NanoRacks, LLC.
The MinXSS will observe soft X-rays from the sun, which can disrupt Earth’s upper atmosphere and hamper radio and GPS signals traveling through the region. The intensity of the soft x-ray emissions emitted from the sun is continuously changing over a large range—with peak emission levels occurring during large eruptions on the sun called solar flares.
NASA’s Cassini spacecraft has detected the faint but distinct signature of dust coming from beyond our solar system. The research, led by a team that includes scientists at the University of Colorado and LASP, will be published in the journal Science on Friday, April 15, 2016.
Cassini has been in orbit around Saturn since 2004, studying the giant planet, its rings, and its moons. The spacecraft has also sampled millions of ice-rich dust grains with its Cosmic Dust Analyzer (CDA) instrument. LASP research scientists Sascha Kempf, Sean Hsu, and Eberhard Grün are all co-investigators for the Cassini CDA instrument and co-authors of the paper.
A LASP-led and University of Colorado Boulder student-built instrument riding on NASA’s New Horizons spacecraft found only a handful of dust grains, the building blocks of planets, when it whipped by Pluto at 31,000 miles per hour last July.
Data downloaded and analyzed by the New Horizons team indicated the space environment around Pluto and its moons contained only about six dust particles per cubic mile, said LASP planetary scientist and CU-Boulder Professor Fran Bagenal, who leads the New Horizons Particles and Plasma Team.
“The bottom line is that space is mostly empty,” said Bagenal. “Any debris created when Pluto’s moons were captured or created during impacts has long since been removed by planetary processes.”
Scientists involved in NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission, which is being led by the LASP team at the University of Colorado Boulder, have identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm and wet environment that might have supported surface life to the cold, arid planet Mars is today.
MAVEN data have enabled researchers to determine the rate at which the Martian atmosphere currently is losing gas to space via stripping by the solar wind. The findings reveal that the erosion of Mars’ atmosphere increases significantly during solar storms. The scientific results from the mission appear in the Nov. 5 issues of the journals Science and Geophysical Research Letters.
In recognition of his accomplishments and exceptional scientific contributions, LASP research associate W.K. (Bill) Peterson has been elected as a fellow of the American Geophysical Union (AGU). Peterson is being recognized by his peers in the scientific community for his outstanding work in Earth and space sciences with an honor that is bestowed upon no more than 0.1% of the AGU membership annually.
After a nine-year journey of 3 billion miles, a piano-sized, power-packed NASA spacecraft has an upcoming date with history that some University of Colorado Boulder students, faculty and alumni wouldn’t miss for the world.
The moon is engulfed in a permanent but lopsided dust cloud that increases in density when annual events like the Geminids spew shooting stars, according to a new study led by LASP scientists at the University of Colorado Boulder.
The cloud is made up primarily of tiny dust grains kicked up from the moon’s surface by the impact of high-speed, interplanetary dust particles, said CU-Boulder physics Professor and LASP research associate Mihály Horányi. A single dust particle from a comet striking the moon’s surface lofts thousands of smaller dust specks into the airless environment, and the lunar cloud is maintained by regular impacts from such particles, said Horányi.
An instrument to be designed and built at LASP has been selected to fly on a NASA mission to Jupiter’s icy moon, Europa, which is believed to harbor a subsurface ocean that may provide conditions suitable for life.
The LASP instrument, known as the SUrface Dust Mass Analyzer (SUDA), will be used to measure the composition of solid particles released from Europa’s surface due to meteoroid bombardment. The instrument also will be able to measure the properties of small, solid particles believed to be spewing from a hidden ocean within the moon, said University of Colorado Boulder Assistant Professor of Physics, Sascha Kempf, who will serve as principal investigator on the project.
Watching the sun is dangerous work for a telescope. Solar instruments in space naturally degrade over time, bombarded by a constant stream of solar particles that can cause a film of material to adhere to the optics. Decades of research and engineering skill have improved protecting such optics, but one crucial solution is to regularly recalibrate the instruments to accommodate such changes.
In mid-May, the seventh calibration mission for an instrument on NASA’s Solar Dynamics Observatory, or SDO, will launch into space onboard a sounding rocket for a 15-minute flight. The instrument to be calibrated is called EVE, short for the EUV Variability Experiment, where EUV stands for extreme ultraviolet. EVE’s job is to observe the total energy output of the sun in EUV light waves. The calibration mission is scheduled to launch on May 21, 2015, on a Terrier-Black Brant suborbital sounding rocket around 3 pm EDT from White Sands Missile Range, New Mexico.
A mission to study dynamic changes in the atmosphere of Mars over days and seasons led by the United Arab Emirates (UAE) involves the University of Colorado Boulder as the leading U.S. scientific-academic partner.
Known as the Emirates Mars Mission, the project is being designed to observe weather phenomena like Martian clouds and dust storms as well as changes in temperature, water vapor and other and gases throughout the layers of the atmosphere. The CU-Boulder part of the mission will be undertaken at LASP.
The mission will be headquartered at and controlled from the Mohammed bin Rashid Space Centre in Dubai, which is affiliated with the Emirates Institution for Advanced Science and Technology. According to Sheikh Mohammed bin Rashid, Vice President and Prime Minister of Dubai, the new Mars probe will be named Hope.
The University of Colorado announced today that it has awarded a five-year contract to SES Government Solutions (SES GS), of Reston, Va., to host a NASA-funded science instrument on board SES-14, a communications satellite to be stationed over the Americas.
The Global-Scale Observations of the Limb and Disk (GOLD) mission, a NASA Explorers mission led from the University of Central Florida and built and operated at the University of Colorado (CU-Boulder), will collaborate with SES GS to place a science instrument on a commercial satellite as a hosted payload. This is the first time a university and a commercial spacecraft operator have teamed to host a NASA science mission. At a cost of roughly 10% of a traditional science satellite, working with a communications satellite represents the most cost-effective way to reach geostationary orbit.
NASA’s MESSENGER mission to Mercury, carrying an instrument designed and built at LASP, is slated to run out of fuel and crash into the planet in the coming days after a wildly successful, four-year orbiting mission chock-full of discoveries.
The mission began in 2004, when the MESSENGER spacecraft launched from Florida on a 7-year, 4.7 billion mile journey that involved 15 loops around the sun before the spacecraft settled into orbit around Mercury in March 2011. LASP provided the Mercury Atmospheric and Surface Composition Spectrometer (MASCS), which has been successfully making measurements of Mercury’s surface and its tenuous atmosphere, called the exosphere, since orbit insertion.
LASP Director and University of Colorado Boulder Distinguished Professor, Daniel Baker, was awarded the Vikram A. Sarabhai Professorship and Prize for 2015, which honors internationally distinguished scholars and is named for the founder of India’s space program.
As part of the award, Baker traveled to the Physical Research Laboratory (PRL) in Ahmedabad, Gujarat, India, in February to work with scientists and students and give seminars and lectures. His primary research interests include the study of physical and energetic particle phenomena in the plasma of planetary magnetospheres.
The Global-scale Observations of the Limb and Disk (GOLD) mission, part of the NASA Explorers Program, passed a rigorous examination on March 5th at the Goddard Space Flight Center in Maryland, enabling the mission to move into the final design and fabrication phase.
At any given moment, our sun emits a range of light waves far more expansive than what our eyes alone can see: from visible light to extreme ultraviolet to soft and hard X-rays. Different wavelengths can have different effects at Earth and, what’s more, when observed and analyzed correctly, those wavelengths can provide scientists with information about events on the sun. In 2012 and 2013, a detector was launched on a sounding rocket for a 15 minute trip to look at a range of sunlight previously not well-observed: soft X-rays.
NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has observed two unexpected phenomena in the Martian atmosphere: an unexplained high-altitude dust cloud and aurora that reaches deep into the Martian atmosphere.
The presence of dust at orbital altitudes from about 93 miles (150 kilometers) to 190 miles (300 kilometers) above the surface was not predicted. Although the source and composition of the dust are unknown, there is no hazard to MAVEN and other spacecraft orbiting Mars.
Following a successful launch at 8:44 p.m. MDT Thursday, NASA’s four Magnetospheric Multiscale (MMS) spacecraft are positioned in Earth’s orbit to begin the first space mission dedicated to the study of a phenomenon called magnetic reconnection. This process is thought to be the catalyst for some of the most powerful explosions in our solar system.
The spacecraft, positioned one on top of the other on a United Launch Alliance Atlas V-421 rocket, launched from Cape Canaveral Air Force Station in Florida. After reaching orbit, each spacecraft deployed from the rocket’s upper stage sequentially, in five-minute increments, beginning at 10:16 p.m., with the last separation occurring at 10:32 p.m. NASA scientists and engineers were able to confirm the health of all separated spacecraft at 10:40 p.m.
Comprised of four identical, octagonal spacecraft flying in a pyramid formation, the MMS mission is designed to better understand the physical processes of geomagnetic storms, solar flares, and other energetic phenomena throughout the universe.
Scientists with NASA’s Cassini mission, led by LASP and University of Colorado postdoctoral researcher, Sean Hsu, have found that microscopic grains of rock detected near Saturn imply hydrothermal activity is taking place within the moon Enceladus.
This is the first clear indication of an icy moon having hydrothermal activity—in which seawater infiltrates and reacts with a rocky crust, emerging as a heated, mineral-laden solution. The finding adds to the tantalizing possibility that Enceladus, which displays remarkable geologic activity including geysers, could contain environments suitable for living organisms.
The results were published today in the journal Nature.
LASP will serve as the Science Operations Center for a NASA mission launching this month to better understand the physical processes of geomagnetic storms, solar flares and other energetic phenomena throughout the universe.
The $1.1 billion Magnetospheric Multiscale (MMS) mission will be comprised of four identical, octagonal spacecraft flying in a pyramid formation, each carrying 25 instruments. The goal is to study in detail magnetic reconnection, the primary process by which energy is transferred from the solar wind to Earth’s protective magnetic space environment known as the magnetosphere, said LASP Director Daniel Baker, Science Operations Center (SOC) lead scientist for MMS.
Two NASA and one European spacecraft, including NASA’s MAVEN mission—led by LASP—have gathered new information about the basic properties of a wayward comet that buzzed by Mars Oct. 19, directly detecting its effects on the Martian atmosphere.
Data from observations carried out by MAVEN, NASA’s Mars Reconnaissance Orbiter (MRO) and the European Space Agency’s Mars Express spacecraft revealed that debris from the comet, known officially as Comet C/2013 A1 Siding Spring, caused an intense meteor shower and added a new layer of ions, or charged particles, to the ionosphere. The ionosphere is an electrically charged region in the atmosphere that reaches from about 75 miles (120 kilometers) to several hundred miles above the Martian surface.
Using the observations, scientists were able to make a direct connection between the input of debris from the meteor shower to the subsequent formation of the transient layer of ions—the first time such an event has been observed on any planet, including Earth, said the MAVEN research team.
NASA’s MAVEN spacecraft has provided scientists their first look at a storm of energetic solar particles at Mars and produced unprecedented ultraviolet images of the tenuous oxygen, hydrogen and carbon coronas surrounding the Red Planet, said LASP Associate Director for Science and University of Colorado Boulder Professor Bruce Jakosky, the mission’s principal investigator.
In addition, the new observations allowed scientists to make a comprehensive map of highly variable ozone in the Martian atmosphere underlying the coronas, he said. The spacecraft entered Mars’ orbit Sept. 21 and is in the process of lowering its orbit and testing its instruments. The $671 million Mars Atmosphere and Volatile EvolutioN mission, or MAVEN, was launched toward Mars on Nov. 18, 2013, to help solve the mystery of how the Red Planet lost most of its atmosphere.
NASA will host a news teleconference at 2 p.m. EDT Tuesday, Oct. 14, to announce early science results from the LASP-led Mars Atmosphere and Volatile Evolution (MAVEN) mission.
Launched in November 2013, the spacecraft entered orbit around Mars on Sept. 21 completing an interplanetary journey of 10 months and 442 million miles (711 million kilometers). MAVEN is the first spacecraft devoted to exploring and understanding the Martian upper atmosphere to help scientists understand climate change over the Red Planet’s history.
NASA has awarded a team led by the University of Colorado Boulder, which includes LASP scientists, more than $7 million to study aspects of the origins, evolution, distribution and future of life in the universe.
The team, led by CU-Boulder Professor Alexis Templeton of the geological sciences department, will be researching what scientists call “rock-powered life.” Rocky planets store enormous amounts of chemical energy, that, when released through the interaction of rocks and water, have the ability to power living systems on Earth as well as on other planets like Mars, said Templeton, principal investigator on the effort.
The LASP-led Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has obtained its first observations of the extended upper atmosphere surrounding Mars.
The Imaging Ultraviolet Spectrograph (IUVS) instrument obtained these false-color images eight hours after the successful completion of Mars orbit insertion by the spacecraft at 10:24 p.m. EDT Sunday, Sept. 21 after a 10-month journey.
In New Mexico on the morning of Aug. 18, a high-altitude balloon successfully carried the HyperSpectral Imager for Climate Science (HySICS) instrument to an altitude of 123,000 feet, above most of the Earth’s atmosphere, to reach space-like conditions and demonstrate new technologies for acquiring high-accuracy science measurements of the Earth.
Scientists use outgoing shortwave radiance, or the amount of sunlight scattered from Earth’s surface and atmosphere and reflected back toward space, as one of the key metrics for studying our planet’s dynamic climate. Watching these radiances over time helps researchers monitor and better understand the causes of environmental changes and global warming.
A NASA mission to Mars led by LASP is set to slide into orbit around the red planet on Sept. 21 to investigate how its climate has changed over the eons, completing a 10-month interplanetary journey of 442 million miles.
The orbit-insertion maneuver will begin with six thruster engines firing to shed some of the velocity from the spacecraft, known as the Mars Atmosphere and Volatile EvolutioN, or MAVEN mission. The thruster engines will ignite and burn for 33 minutes to slow the spacecraft, allowing it to be captured into an elliptical orbit around Mars.
The importance of Mars exploration and how the aerospace industry partners with university researchers to advance one of Colorado’s leading economic sectors will be featured at a free program Monday, Sept. 8, in south Denver.
Aerospace leaders will discuss the importance of Mars exploration and the role of the Mars Atmosphere and Volatile EvolutioN, or MAVEN mission, the involvement of Colorado companies in space exploration and the value of public/private partnerships involving university-based research. Speakers will include Jim Green, director of NASA planetary science; Nick Schneider, MAVEN co-investigator and professor in the CU-Boulder Department of Astrophysical and Planetary Sciences; Guy Beutelschies, space exploration systems director, Lockheed Martin; Jim Sponnick, vice president of Atlas and Delta programs, United Launch Alliance; and Patrick Carr, vice president and general manager of command, control and communications systems, Exelis.
Based on a recommendation from NASA’s 2014 Senior Review of its operating missions, the planet hunting Kepler space telescope has received a two-year extension to operate in a new two-wheel mode.
The approval allows the K2 mission to continue exoplanet discovery using two of its four original reaction wheels, and introduces new scientific observation opportunities to observe notable star clusters, young and old stars, active galaxies and supernovae.
At the conclusion of a highly successful 130-day mission, the NASA Lunar Atmosphere and Dust Environment Explorer (LADEE) is planned to impact the surface of the moon on April 21, 2014. LADEE carries the Lunar Dust Experiment (LDEX), which is the latest in a series of dust detectors designed and built at LASP.
A new study led by LASP research scientist Stuart Robbins indicates that volunteer “citizen scientists” counted lunar craters at rates comparable to professional scientists. Using images from NASA’s Lunar Reconnaissance Orbiter, volunteers for CosmoQuest, which contributes real science data to NASA missions, analyzed the high-resolution photos of the Moon for impact craters. Robbins and his co-authors then compared the volunteers’ results to those of eight professional planetary crater-counters.
The MAVEN spacecraft and all of its science instruments have completed their initial checkout, and all of them are working as expected. This means that MAVEN is on track to carry out its full science mission as originally planned.
The mission is designed to explore Mars’ upper atmosphere. It will determine the role that escape of gas from the atmosphere to space has played in changing the climate throughout the planet’s history. MAVEN was launched on November 18, 2013, and will go into orbit around Mars on the evening of Sept. 21, 2014 (10 p.m. EDT).
After a 5-week commissioning phase in orbit, during which it will get into its science-mapping orbit, deploy its booms, and do a final checkout of the science instruments, it will carry out a one-Earth-year mission. It will observe the structure and composition of the upper atmosphere, determine the rate of escape of gas to space today and the processes controlling it, and make measurements that will allow it to determine the total amount of gas lost to space over time.
NASA has approved a 28-day mission extension for the Lunar Atmosphere and Dust Environment Explorer (LADEE). LASP provided the Lunar Dust Experiment (LDEX) onboard the satellite, which launched on September 6, 2013 and is now expected to impact the surface of the moon in late April 2014.
Due to accurate and efficient propulsion and guidance over the course of the mission to date, the spacecraft has more fuel remaining than mission operators originally expected. The extra propellant will provide an opportunity for LADEE to gather an additional full lunar cycle worth of very low-altitude data to help scientists unravel the mysteries of the moon’s tenuous atmosphere and dust environment.
As 2013 draws to a close, it is amazing to reflect on all of LASP’s accomplishments in its 65th year! The last four months of the year were punctuated by launches to the moon, and Earth and Mars orbits for the LDEX, TCTE, and MAVEN instruments that LASP designed, built, and now operates.
A LASP-led mission that will investigate how Mars lost its atmosphere and abundant liquid water launched into space on November 18 at 11:28 a.m. MST from Cape Canaveral Air Force Station in Florida.
The Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft separated from an Atlas V Centaur rocket’s second stage 53 minutes after launch. The solar arrays deployed approximately one hour after launch and currently power the spacecraft. MAVEN now is embarking on a 10-month interplanetary cruise before arriving at Mars next September.
MAVEN is set to launch aboard a United Launch Alliance Atlas V 401 rocket Nov. 18. The two-hour launch window extends from 1:28 to 3:28 p.m. EST. Liftoff will occur from Cape Canaveral Air Force Station’s Space Launch Complex 41.
Launch commentary coverage, as well as prelaunch media briefings, will be carried live on NASA Television and the agency’s website.
The following is a list of MAVEN launch-related briefings, events, and activities.
On Sept. 29, 2013, a scientific balloon launched from the Columbia Scientific Balloon Facility in Fort Sumner, NM, flying an instrument that scientists hope will eventually establish a new long-term benchmark data set pertaining to climate change on the Earth.
The instrument, funded by a $4.7 million NASA Earth Science Technology Office Instrument Incubator Program contract, is intended to acquire extremely accurate radiometric measurements of Earth relative to the incident sunlight. Over time, such measurements can tell scientists about changes in land-use, vegetation, urban landscape use, and atmospheric conditions on our planet. Such long-term radiometric measurements from the HyperSpectral Imager for Climate Science (HySICS) instrument can then help scientists identify the drivers of climate change.
Haiku recognized in the LASP-led MAVEN message-to-Mars contest were announced today on the Going to Mars campaign website. Haiku authors from around the world—including Palestine, India, Australia, and Europe—entered the contest. The top five winners—all those whose haiku received 1,000 votes or more—include popular British blogger Benedict Smith and well-known American poet Vanna Bonta. Other entries receiving special recognition include MAVEN team selections in categories ranging from haiku specifically about MAVEN to humorous haiku.
The LASP-led Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has arrived in Florida to begin final preparations for launch this November. The spacecraft was shipped from Lockheed Martin Space Systems in Littleton, Colo., to the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center on Friday.
LASP director and research scientist Dan Baker is co-author of new research that indicates that a massive particle accelerator exists in the Van Allen radiation belts, a harsh band of super-energetic, charged particles surrounding our planet. The results were published in Science magazine today.
The LASP-led MAVEN Going to Mars campaign has opened public voting on submissions to the message to Mars contest. Messages are in the form of three-line poems called haiku. The public will select the top three haiku via open voting on an online interface. Winning haiku will be announced on the MAVEN website on August… Read more »
The winner of the LASP-run MAVEN student art contest turns out be the work of more than a single young person. The First Place entry, selected by online public vote, was the work of a Colorado-based Kindergarten Enrichment class.
A multimillion dollar LASP instrument package to study space weather has passed its pre-installation testing and is ready to be incorporated onto a National Oceanic and Atmospheric Administration satellite for a 2015 launch.
The LASP-operated NASA Kepler spacecraft has discovered two planetary systems that include three super-Earth-sized planets in the “habitable zone,” where the surface temperature of a planet may sustain liquid water.
NASA has announced that LASP will collaborate on a $55 million project to build and launch an instrument to provide unprecedented imaging of the Earth’s upper atmosphere from a geostationary orbit.
The kind of information the Global-scale Observations of the Limb and Disk (GOLD) mission will collect will have a direct impact on man’s understanding of space weather and its impact on communication and navigation satellites.
NASA has extended the Kepler mission through fiscal year 2016, adding four years to Kepler’s search for Earth-like planets in the Milky Way galaxy and allowing LASP to continue our work operating the spacecraft. A team of 20 University of Colorado students and 16 LASP professionals control the Kepler spacecraft from the LASP Mission Operations… Read more »
CU-Boulder students, working under the guidance of LASP scientists and engineers, have finished building a satellite to study space weather and have sent it to California Polytechnic Institute to begin integration with launch vehicle systems. More than 50 graduate and undergraduate students have contributed to designing and building the Colorado Student Space Weather Experiment (CSSWE), an $840,000 CubeSat mission funded by the National Science Foundation. The satellite is scheduled to launch into low-Earth polar orbit in early August 2012 as a secondary payload under NASA’s Educational Launch of Nanosatellites (ELaNa) program.
In recognition of their accomplishments and exceptional scientific contributions, two LASP scientists have been elected as fellows of the American Geophysical Union (AGU). Bruce Jakosky and Cora Randall have been recognized by their peers for their outstanding work in Earth and space sciences with an honor that is bestowed upon not more than 0.1% of the AGU membership annually.
Using data from the NASA New Horizons mission to Pluto, LASP scientists have made new measurements of interplanetary dust density. The data, collected from the CU-Boulder student-built Student Dust Counter (SDC) and the meteoroid detector on the Pioneer 10 spacecraft, represent measurements of the micro-sized dust grains from the Earth out to the present position of the SDC, at approximately 20 Astronomical Units (AU). One AU is equal to the average distance from the Sun to the Earth, or approximately 93 million miles (149.5 million km).
Using data from the NASA Cassini mission, a team of scientists led by LASP researcher Sean Hsu, has successfully modeled dust streams being expelled from Saturn at speeds of more than 62 miles (100 km) per second. The data, taken from the Cosmic Dust Analyzer (CDA) and the magnetometer on board Cassini, provide new information about the sources of the dust, as well as interactions within the mix of subatomic particles in which the charged dust is immersed, called dusty plasma.
As part of the upcoming American Geophysical Union Fall Meeting in San Francisco, LASP director, Dan Baker, will serve as a panelist for a workshop on space weather. The workshop, titled, “Getting Ready for Solar Max: Separating Space Weather Fact from Fiction,” will be held on Tuesday, December 6, at 10 a.m. PT. Baker will begin the workshop with an overview of our current understanding of the Sun-Earth system, including solar variability and its interaction with Earth’s magnetosphere.
In recognition of his accomplishments and groundbreaking insights in the field of atmospheric science, LASP scientist and CU-Boulder Professor Peter Pilewskie has been named a recipient of the prestigious Humboldt Research Award. Pilewskie has been at LASP since 2004, where he performs research on the effects of clouds and aerosols on solar energy in the Earth’s atmosphere. He is also a professor in the Department of Atmospheric & Oceanic Sciences and serves as the director of the collaborative LASP/NASA Goddard Sun-Climate Research Center.
NASA’s Mars Atmosphere and Volatile EvolutioN (MAVEN) mission has achieved another significant milestone on its way towards launch in November 2013. Lockheed Martin has completed building the primary structure of the MAVEN spacecraft at its Space Systems Company facility near Denver.
NASA’s Upper Atmosphere Research Satellite (UARS), launched in September 1991 and deployed from the Space Shuttle Discovery (STS-48), is re-entering Earth’s atmosphere and will complete its decent on Friday, September 23. LASP designed and built the Solar Stellar Irradiance Comparison Experiment (SOLSTICE) on board UARS and operated the instrument after launch. Throughout 14 years of successful operations, SOLSTICE made precise measurements of the Sun’s ultraviolet and far ultraviolet spectral irradiance.
September 2011 marks a significant milestone for LASP, as our Mission Operations and Data Systems (MODS) team celebrates 15 years of continuous spacecraft operations. From long-standing science missions, such as ICESat, which have brought in important data over years—to newer missions, such as Kepler’s exciting search for Earth-like planets—LASP MODS has offered reliable spacecraft operations to agencies including NASA.
The Sun is the dominant source of energy for Earth’s atmosphere. Scientists are interested in determining how the Sun’s output affects Earth’s climate and the ways specific events can disrupt space weather applications, space-based technologies, and radio communications. New observations of solar extreme ultraviolet (EUV) irradiance from the LASP-designed and built EUV Variability Experiment (EVE) on NASA’s Solar Dynamics Observatory (SDO) are adding another piece to this complicated puzzle that may help scientists more accurately predict space weather events.
Several LASP scientists are involved in NASA’s upcoming Juno mission to Jupiter. Scheduled to launch on August 5, 2011, the mission will improve understanding of our solar system origins by revealing details about the formation and evolution of the gas giant. The spacecraft will embark on a five-year, 400-million-mile voyage to Jupiter, where it will orbit the planet 33 times, collecting data for more than one Earth year.
The CU/LASP-led mission to Mars, devoted to understanding the Martian upper atmosphere, reached a major milestone last week when it successfully completed its Mission Critical Design Review (CDR) at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. An independent review board, comprised of reviewers from NASA and several external organizations, met from July 11-15 to validate the system design of the Mars Atmosphere and Volatile Evolution, or MAVEN, mission.
LASP/CU-Boulder students are designing and building a satellite that will study space weather—changes in near-Earth space conditions that adversely affect Earth-orbiting spacecraft and communication technologies. The Colorado Student Space Weather Experiment (CSSWE) is an $840,000 CubeSat mission funded by the National Science Foundation. CSSWE is scheduled to launch into low-Earth polar orbit in June 2012 as a secondary payload under NASA’s Educational Launch of Nanosatellites (ELaNa) program.
A new video that introduces the unique story of LASP student involvement in a NASA satellite instrument is now available. The video features students involved in the design, production, and operation of the Venetia Burney Student Dust Counter (SDC), an instrument aboard the NASA New Horizons mission to Pluto. Under the supervision of professional education staff, LASP undergraduate student Alex Thom compiled the video from archived mission footage and interviews.
At approximately 7 p.m. MT on Thursday, March 17, after more than six and a half years and a nearly 5 billion mile journey, NASA’s MESSENGER mission became the first spacecraft to enter into orbit around the planet Mercury.
On March 23, 2011, LASP launched a sounding rocket intended to calibrate the Extreme ultraviolet Variability Experiment (EVE) on the NASA Solar Dynamics Observatory (SDO). The rocket carries an almost exact replica instrument as the satellite version SDO EVE instrument, which will help to determine any long-term degradation of the EVE optical system and will enable EVE to obtain the most accurate measurements possible of solar irradiance.
At Vandenberg Air Force Base in California, engineers are preparing the next Earth-observing NASA mission, Glory, which is slated to launch in late February. Glory carries the LASP-built Total Irradiance Monitor (TIM) instrument, which will be directed towards the sun and will measure the intensity of solar radiation that enters the Earth’s atmosphere.
