| Description |
Français : Manoeuvre d'insertion en orbite de la sonde spatiale MAVEN de la NASA en septembre 2014. A : trajectoire de la sonde en provenance de la Terre, B La sonde spatiale utilise sa propulsion pour s'insérer en orbite autour de Mars en passant à 380 km au-dessus du pôle Nord de la planète, C Le freinage dure 33 minutes (segment rouge) et consomme la moitié du carburant embarqué, D L'orbite initiale a une période de 35 heures. Dans les jours la sonde spatiale utilise à plusieurs reprises sa propulsion pour réduire sa période à 4 heures et demi. English: This image shows an artist concept of the trajectory of NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission as it approaches the Red Planet. On Sept. 21, 2014, MAVEN will enter orbit around Mars, completing an interplanetary journey of 10 months and 442 million miles (711 million kilometers). Launched in November 2013, the mission will explore the Red Planet’s upper atmosphere, ionosphere and interactions with the sun and solar wind. Scientists will use MAVEN data to determine the role that loss of volatiles from the Mars atmosphere to space has played through time, giving insight into the history of Mars' atmosphere and climate, liquid water, and planetary habitability.
MAVEN is part of NASA's Mars Scout program, funded by NASA Headquarters and managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland. |
