#NASA just lost contact with #MAVEN #Mars orbiter, and will soon lose another one
Telemetry showed #spacecraft was working normally before passing behind Mars, but spacecraft did not resume communications after emerging from behind the planet.
MAVEN is newest of NASA’s 3 operational Mars orbiters. But NASA’s two other Mars orbiters have been in space for more than 20 years. The older of the two, named #MarsOdyssey, has been at Mars since 2001 and will soon run out of fuel

NASA just lost contact with a Mars orbiter, and will soon lose another one

If NASA is serious about exploring Mars, it’s past time to send new missions.

Odyssey toont gigantische Marsvulkaan die door ijswolken breekt

De Mars Odyssey ruimtesonde van de NASA heeft een adembenemende nieuwe opname gemaakt van de enorme vulkaan Arsia Mons die door ochtendlijke ijswolken oprijst en een zeldzame, astronautachtige blik op de horizon van Mars biedt.

Arsia Mons, een oude vu
