The Mars Atmosphere and Volatile Evolution mission (MAVEN) launched on November 18, 2013, and entered orbit around Mars on September 21, 2014. The mission’s goal is to explore the planet’s upper atmosphere, ionosphere, and interactions with the Sun and solar wind. Scientists will use MAVEN data to explore the loss of volatile compounds—such as CO2, N2, and H2O—from the Martian atmosphere to space. Understanding atmospheric loss will give scientists insight into the history of Mars' atmosphere and climate, liquid water, and planetary habitability.

MAVEN Status Update: September 21, 2015

September 21

— MAVEN Principal Investigator Bruce Jakosky

As of today, MAVEN has been in orbit around Mars for one Earth year! And it’s been an action-packed year.

Some of the highlights include:

  • Getting into orbit!
  • Surviving the encounter with Comet Siding Spring
  • Commissioning the spacecraft
  • Carrying out ten months (so far) of observations during our primary mission
  • Carrying out four deep-dip campaigns

The success of the mission so far is a direct result of the incredibly hard work of everybody who works (and has worked) on ‪‎MAVEN‬. This one year at ‪Mars‬ reflects the tremendous efforts over the preceding dozen years. And the mission continues—we still have two months to go in our primary mission, and then we begin our extended mission. We’re obtaining an incredibly rich data set that is on track to answer the questions we originally posed for MAVEN and that will serve the community for a long time to come.

I hope everybody is as proud of what we’ve accomplished as I am! And here’s to the next year of exciting observations, analyses, and results!
