442 Million Miles Later Nasa S Maven Spacecraft Enters Mars Orbit Sep 22, 2014. release 14 260. nasa’s mars atmosphere and volatile evolution (maven) spacecraft successfully entered mars’ orbit at 10:24 p.m. edt sunday, sept. 21, where it now will prepare to study the red planet’s upper atmosphere as never done before. maven is the first spacecraft dedicated to exploring the tenuous upper atmosphere of. On sept. 21, 2014, maven will enter orbit around mars, completing an interplanetary journey of 10 months and 442 million miles (711 million kilometers). maven’s journey to mars requires a 33 minute engine burn to slow the spacecraft so that it can be captured into martian orbit. maven’s trajectory is depicted by the blue line, showing its.

The apoapsis altitude (highest point in orbit) dropped from about 6050 to about 4570 km, an orbit change that improves maven's availability to support relay communications with nasa's landers and rovers on the surface of mars. the orbit period dropped from 4.4 hours to roughly 3.7 hours. "the final post aerobraking orbit resulted from an. Active mission. the mars atmosphere and volatile evolution (maven) mission will determine how much of the martian atmosphere has been lost over time by measuring the current rate of escape to space and gathering enough information about the relevant processes to allow extrapolation backward in time. type. orbiter. launch orbit insertion. Maven’s journey to mars requires a 33 minute engine burn to slow the spacecraft so that it can be captured into martian orbit. maven’s trajectory is depicted by the blue line, showing its initial approach and the beginning of the 35 hour capture orbit.
