NASA's Maven spacecraft reaches Mars this weekend More The Associated Press FILE - In this Friday, Sept. 27, 2013 file photo, technicians work on NASA’s next Mars-bound spacecraft, the Mars Atmosphere and Volatile Evolution (MAVEN), at the Kennedy Space Center in Cape Canaveral, Fla. NAS...
In December 2022, NASA’s MAVEN mission observed a rare solar event causing the solar wind to “disappear.” This led to significant changes in Mars’ atmosphere and magnetosphere, including their expansion. Scientists, astounded by the data, formed a working group to study this phenomenon. Cred...

Physics. This setup supports MAVEN’s goals of understanding Mars’ atmospheric loss, with additional navigation and communication assistance provided by NASA’s Jet Propulsion Laboratory. As it nears its tenth year at Mars, MAVEN continues to contribute critical data to our understanding of ...
MAVEN will continue to study the Martian atmosphere and learn more about how water behaves on the Red Planet. Let’s hope NASA, SpaceX, and every other group looking to see humans live and work on Mars one day are paying close attention to the data. ...
Speaking from spacecraft-builder Lockheed Martin's control center near Denver, Mitchell said the MOI rocket firing ran just 11 seconds longer than predicted, "which means MAVEN nailed it. Right on the money." The data from the spacecraft backed that up. The low point of the resulting ellipti...
Magnetometer: This instrument collects data about the magnetic environment as MAVEN orbits Mars. The magnetometer gives other instruments important information as well, NASA officials said, because magnetic fields can affect the upper atmosphere of the planet. Neutral Gas and Ion Mass Spectrometer: This...
The MAVEN has completed its two-year mission in space, but its fuel allows it to last through 2030, according to NASA. The orbiter carries an ultra high-frequency radio that allows it to relay data between Earth and rovers or landers on Mars, including the Curiosity rover. ...
