Propellant tank installed

This photo taken March 3 shows the large hydrazine propellant tank prior to integration with the core structure of the MAVEN spacecraft at a Lockheed Martin clean room near Denver, Colo. The tank will hold 450 gallons of hydrazine propellant and is 6 feet 2 inches tall. The tank was built by ATK Aerospace Group, Commerce, Calif. The primary structure in the background is cube shaped at 7.5 feet x 7.5 feet x 6.5 feet high. Built out of composite panels comprised of aluminum honeycomb sandwiched between graphite composite face sheets, the entire structure only weighs 275 pounds. MAVEN is scheduled to launch in November 2013 and will be the first mission devoted to understanding the Martian upper atmosphere. The goal of the Mars Atmosphere And Volatile EvolutioN program is to determine the role that loss of atmospheric gas to space played in changing the Martian climate through time. MAVEN will determine how much of the Martian atmosphere has been lost over time by measuring the current rate of escape to space and gathering enough information about the relevant processes to allow extrapolation backward in time.

MAVEN’s principal investigator is based at the University of Colorado at Boulder’s Laboratory for Atmospheric and Space Physics. The university will provide science operations, build instruments, and lead Education/Public Outreach. NASA Goddard Space Flight Center in Greenbelt, Md., will manage the MAVEN mission and provide instruments. Lockheed Martin of Littleton, Colo., will build the spacecraft and perform mission operations. The University of California-Berkeley Space Sciences Laboratory will build instruments for the mission. NASA’s Jet Propulsion Laboratory, Pasadena, Calif., will provide Program management via the Mars Program Office, as well as navigation support, the Deep Space Network, and the Electra telecommunications relay hardware and operations.

NASA releases first global rainfall, snowfall map from new mission

Like a lead violin tuning an orchestra, the GPM Core Observatory – launched one year ago on Feb. 27, 2014, as a collaboration between NASA and the Japan Aerospace Exploration Agency – acts as the standard to unify precipitation measurements from a network of 12 satellites. The result is NASA’s Integrated Multi-satellite Retrievals for GPM...
 

 

New NASA Earth Science Missions expand view of our home planet

Four new NASA Earth-observing missions are collecting data from space with a fifth newly in orbit ñ after the busiest year of NASA Earth science launches in more than a decade. On Feb. 27, 2014, NASA and the Japan Aerospace Exploration Agency launched the Global Precipitation Measurement Core Observatory into space from Japan. Data from...
 
 

NASA, ESA telescopes give shape to furious black hole winds

NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and ESA’s (European Space Agency) XMM-Newton telescope are showing that fierce winds from a supermassive black hole blow outward in all directions – a phenomenon that had been suspected, but difficult to prove until now. This discovery has given astronomers their first opportunity to measure the strength of these...
