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.
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.
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.

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 […]
A new study by LASP research scientist Brian Toon and doctoral student Eric Wolf indicates that explaining Earth’s early conditions, which were warm enough to support life despite a 20-percent dimmer Sun, may be simpler than believed. The study, published in the July issue of Astrobiology, indicates that the Archean eon, 2.8 billion years ago, […]
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 MAVEN mission is inviting people from all over the world to submit their names and a unique message online. Participants’ names and the top-voted messages will be burned to a specially-designed DVD and sent to the Red Planet aboard the MAVEN spacecraft, scheduled to launch in November, 2013.
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.
