SUMMARY: After a few days of delays, NASA's Mars Reconnaissance Orbiter has begun its journey towards the Red Planet. The orbiter lifted off atop a massive Atlas V launch vehicle from Cape Canaveral at 1143 UTC (7:43 am EDT). The spacecraft established radio contact with controllers on the ground 61 minutes after launch and confirmed that everything's working well. MRO will reach Mars on March 10, 2006, and begin several months of aerobraking maneuvers to lower its orbit.

How many probes are now going around this desolate place?

ESA's Express, Nasa has two? this being the third? The Russians as far as I know only ever wanted to get to Phobos. What are the Chinese up to, the Moon or Mars? :huh:

There are currently 10 satellites orbiting Mars, three of them are still in operation:

Mariner 9 (USA), Arrived Nov 13, 1971.
Mars 2 (Russia), Arrived Nov 27, 1971.
Mars 3 (Russia), Arrived Dec 2, 1971.
Mars 5 (Russia), Arrived Feb 2, 1974.
Viking 1 Orbiter (USA), Arrived Jul 20, 1976.
Viking 2 Orbiter (USA), Arrived Sep 3, 1976.
Phobos 2 (Russia), Arrived Jan 1989.

Mars Global Surveyor (USA), Arrived Sep 11, 1997. Operating.
Mars Odyssey (USA), Arrived Oct 24, 2001. Operating.
Mars Express (ESA), Arrived Dec 25, 2003. Operating.

In addition, there are two operating rovers on the surface of Mars.
So in total, there are five operating robots studying Mars currently "in situ".
