Today, NASA’s MAVEN spacecraft celebrates four years in orbit studying the upper atmosphere of the Red Planet and how it interacts with the Sun and the solar wind. To mark the occasion, the team has released a selfie image of the spacecraft at Mars.
MAVEN’s selfie was made by looking at ultraviolet wavelengths of sunlight reflected off of components of the spacecraft. The image was obtained with the Imaging Ultraviolet Spectrograph (IUVS) instrument, built at LASP, that normally looks at ultraviolet emissions from the Martian upper atmosphere. The IUVS instrument is mounted on a platform at the end of a 1.2-m boom (its own “selfie stick”), and by rotating around the boom can look back at the spacecraft. The selfie was made from 21 different images, obtained with the IUVS in different orientations, that have been stitched together.
Science fiction writers have long featured terraforming, the process of creating an Earth-like or habitable environment on another planet, in their stories. Scientists themselves have proposed terraforming to enable the long-term colonization of Mars. A solution common to both groups is to release carbon dioxide gas trapped in the Martian surface to thicken the atmosphere and act as a blanket to warm the planet.
However, Mars does not retain enough carbon dioxide that could practically be put back into the atmosphere to warm Mars, according to a NASA-sponsored study led by LASP Associate Director for Science Bruce Jakosky. Transforming the inhospitable Martian environment into a place astronauts could explore without life support is not possible without technology well beyond today’s capabilities.
LASP-led research has discovered microbes living in a toxic volcanic lake that may rank as one of the harshest environments on Earth. Their findings, published recently online, could guide scientists looking for signs of ancient life on Mars.
The team, led by LASP planetary scientist Brian Hynek, braved second-degree burns, sulfuric acid fumes, and the threat of eruptions to collect samples of water from the aptly-named Laguna Caliente. Nestled in Costa Rica’s Poás Volcano, this body of water is 10 million times more acidic than tap water and can reach near boiling temperatures. It also resembles the ancient hot springs that dotted the surface of early Mars, Hynek said.
The Costa Rican lake supports living organisms—but only one. Hynek and his colleagues found microbes belonging to just a single species of bacteria in the lake water, a rock-bottom level of diversity.
How long might a rocky, Mars-like planet be habitable if it were orbiting a red dwarf star? It’s a complex question but one that NASA’s Mars Atmosphere and Volatile Evolution mission can help answer.
“The MAVEN mission tells us that Mars lost substantial amounts of its atmosphere over time, changing the planet’s habitability,” said David Brain, a MAVEN co-investigator at LASP. “We can use Mars, a planet that we know a lot about, as a laboratory for studying rocky planets outside our solar system, which we don’t know much about yet.”
At the fall meeting of the American Geophysical Union on Dec. 13, 2017, in New Orleans, Louisiana, Brain, also a professor in the CU Boulder astrophysical and planetary sciences department, described how insights from the LASP-led MAVEN mission could be applied to the habitability of rocky planets orbiting other stars.
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.
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.
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.
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.
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.
Mars turned cold and dry long ago, but LASP-led research at the University of Colorado Boulder has unveiled evidence of an ancient lake that likely represents some of the last potentially habitable surface water ever to exist on the Red Planet.
The study, published Thursday in the journal Geology, examined an 18-square-mile chloride salt deposit (roughly the size of the city of Boulder) in the planet’s Meridiani region near the Mars Opportunity rover’s landing site. As seen on Earth in locations such as Utah’s Bonneville Salt Flats, large-scale salt deposits are considered to be evidence of evaporated bodies of water.
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.
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.
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.
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.
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.
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.
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.

Members of the worldwide public are invited to participate in NASA’s Mars Atmosphere and Volatile EvolutioN (MAVEN) mission through a new Education & Public Outreach (E/PO) effort called the Going to Mars campaign. MAVEN, which is the first mission devoted to understanding the Martian upper atmosphere, has a robust E/PO program designed to engage a variety of audiences in the mission.
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.
LASP scientist and CU-Boulder Department of Geological Sciences Assistant Professor, Brian Hynek, led a recent study detailing the earliest history of the development of the Tharsis volcanoes on Mars. The Tharsis region, one of the most prominent features on Mars, covers one quarter of the planet, rises 10 km above the surrounding flatlands, and has had near-continuous volcanic activity for roughly 4 billion years.
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.
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.
A recent study co-authored by LASP researcher Brian Toon used models to predict which regions on Mars could have ice caves. Ice caves are sometimes found on Earth in lava tubes left over from previous volcanic activity; on Mars, these ice caves could allow ice to exist in middle latitudes, where many lava tubes have… Read more »
NASA announced today that the CU/LASP-led mission to Mars to investigate how the planet lost much of its atmosphere eons ago has been approved by the space agency to move into the development stage.
A vast ocean likely covered one-third of the surface of Mars some 3.5 billion years ago, according to a new study conducted by LASP scientists, further supporting the idea of a sustained sea on the Red Planet.
The study, authored by Gaetano Di Achille and Brian Hynek, is the first to combine the analysis of water-related features, including scores of delta deposits and thousands of river valleys to test for the occurrence of an ocean sustained by a global hydrosphere on early Mars.
A University of Colorado at Boulder research team has discovered the first definitive evidence of shorelines on Mars, an indication of a deep, ancient lake there and a finding with implications for the discovery of past life on the Red Planet. Estimated to be more than 3 billion years old, the lake appears to have… Read more »
