Oddly, the first Martian artificial satellite was inserted successfully into Martian Orbit 46 years ago.

 

Mars 2 was launched by the Soviet Union in 1971. The potent Russian empire had put a satellite into Martian orbit, hundreds of millions of miles away. Mars 2 was a sacrament to the missile technology that so counted during the Cold War. Mars 3 followed Mars 2 by only 11 days went into Martian orbit and lasted from December 1971 until August 1972. Both Mars 2 and Mars 3 were satellite lander packages. The lander from mars 2 crashed onto the planet surface when the vehicle parachutes failed to deploy.

 

Mars 2 consisted of a landing capsule that was 1.2 meter diameter and 2.9 meter conical aerodynamic braking shield and retro rockets. It’s mass was 1210 kg all controlled by gas operated micro engines and pressurized nitrogen packets for attitude control. Foam would absorb the shock of the landing and for petals would open righting to ship to reveal the instrumentation. It was equipped with two TVs and a mass spectrometer.

The lander was battery powered.

 

 

 

 

NASA launched Mariner 9 in 1971 and beta Mars 2 and Mars 3 to the orbit to become the first man made object in orbit around Mars. It sent back 7329 photos and operated for a year.

 

Mars 5 was launched by the Soviet Union in July of 1973 followed soon thereafter by the US ultra successful Viking 1 and Viking 2 landers. So there are 14 man made satellites orbiting Mars and six of them are not only active, one has been working for 15 years, the Mars Odyssey, launched in April 2001.
