Mission Timeline

MAVEN launched on November 18, 2013 (watch video of launch), and entered the orbit of Mars on September 21, 2014. The first fuel burn inserted the spacecraft into a capture orbit with a period of 35 hours (the time it will take to make one complete orbit around Mars) and an altitude of approximately 380 kilometers. Shortly after Mars orbit insertion, a second fuel burn will place the spacecraft into its 4.5-hour period requirement for acquiring data. Three smaller burns will reduce the periapsis altitude (closest distance) of the spacecraft to approximately 150 kilometers, placing MAVEN within the required corridor and a 75° inclination elliptical science mapping orbit.

MAVEN measurements will be made from this orbit over a period of one Earth year, with five 5-day “deep dips” interspersed to sample the entire upper atmosphere. For additional information about MAVEN’s science orbit, please see: http://lasp.colorado.edu/home/maven/science/science-orbit/.

Goddard Space Flight Center (GSFC) will lead the mission design and will manage the mission design and navigation for MAVEN. Operational navigation is led by the Jet Propulsion Laboratory (JPL).

This schedule provides thorough coverage of solar conditions, local time, latitude, and crustal magnetic configuration, and ensures that we obtain the measurements necessary to achieve all science objectives.
