On Sept. 21, 2014, the MAVEN spacecraft will complete roughly 10 months of travel and enter orbit around the Red Planet.
The orbit-insertion maneuver will be carried out as the spacecraft approaches Mars, wrapping up an interplanetary journey of 442 million miles (711 million kilometers). Six thruster engines will fire briefly for a “settling” burn that damps out deviations in pointing. Then the six main engines will ignite two by two in quick succession and will burn for 33 minutes to slow the craft, allowing it to be captured in an elliptical orbit.

This milestone will mark the culmination of 11 years of concept and development for MAVEN, setting the stage for the mission’s science phase, which will investigate ‪#‎Mars‬ as no other mission has.
“We’re the first mission devoted to observing the upper atmosphere of Mars and how it interacts with the sun and the solar wind,” said Bruce Jakosky, principal investigator for ‪#‎MAVEN‬ at the University of Colorado Boulder.
These observations will help scientists determine how much gas from Mars’ atmosphere has been lost to space throughout the planet’s history and which processes have driven that loss.
