Although in November 2006 communication with Mars Global Surveyor was lost, three orbiters ​ — the 2001 Mars Odyssey, the Mars Express, and the Mars Reconnaissance Orbiter — ​ continued their surveillance of the red planet.
Kuigi 2006. aasta novembris side Mars Global Surveyoriga katkes, jätkasid kolm automaatjaama – 2001 Mars Odyssey, Mars Express ja Mars Reconnaissance Orbiter – punase planeedi uurimist.
