MAVEN - Mars Orbit Insertion
|The Mars Atmosphere and Volatile EvolutioN (MAVEN) mission will be the first spacecraft mission dedicated to surveying the upper atmosphere of Mars. MAVEN is a robotic exploration mission to understand the role that loss of atmospheric gas to space played in changing the Martian climate over time. This will help determine when and for how long liquid water could have been stable on the surface, which has implications in answering the question about whether Mars could have ever harbored life.|
MAVEN: In Search of the Missing Atmosphere
NASA’s Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft, built by Lockheed Martin, is on schedule to get to Mars September 21. The 10-month journey began November 18, 2013 when MAVEN was launch aboard a United Launch Alliance Atlas V-401 rocket.
The MAVEN mission will last one Earth year and has eight science instuments. MAVEN will study Mars’ upper atmosphere, how it interacts with the sun and solar winds and how that interaction may have led to the loss of atmosphere and water over time.
What will MAVEN do?
- Determine the current state of the Martian upper atmosphere, ionosphere, and interactions with solar wind
- Measure properties and processes that will allow us to determine the integrated loss of gas to space through time
- Determine the role that loss of volatiles from the Mars atmosphere to space has played through time, exploring the histories of Mars’ atmosphere and climate, liquid water, and planetary habitability.
The science from this mission will give insight into the history of Mars' atmosphere and climate, liquid water, and planetary habitability overall. It will investigate how much of the atmosphere has been lost over time by measuring the current rate of escape to space and gathering enough information about the relevant processes to extrapolate backward in time. MAVEN will carry three instrument suites that are being provided by CU/LASP, Goddard Space Flight Center and the University of California at Berkeley.
