Mars 2: Mars 2 (4M No.171) 19 May 1971 Soviet Union: Orbiter Successful On November 27 it became in short sequence the second spacecraft to orbit another planet. [5] Operated for 362 orbits [6] Proton-K/D: Mars 2 lander (SA 4M No.171) Lander Spacecraft failure First lander to impact Mars. Deployed from Mars 2, failed to land during attempt on ...
Contact with all eight Mars orbiters launched during the 20th century has been lost. NASA's four spacecraft are conjectured to remain in Mars' orbit. Mariner 9, Viking 1 and Viking 2 are expected to lower down into the Martian atmosphere by 2022 and either burn up or crash into the planet's surface. [2] Mars Global Surveyor is expected to crash ...
Spacecraft that have not been precisely located include Mars 2, Mars 3, Mars 6, Mars Polar Lander, and the two Deep Space 2 probes. Orbiters whose orbit could eventually decay and impact the surface, include: Viking 1 and Viking 2 orbiters, Mars Reconnaissance Orbiter , 2001 Mars Odyssey , Mars Express , Mars Global Surveyor , Phobos 2 , Mars 2 ...
The Mars 2 lander crashed into Mars on 27 November 1971, in a failed soft landing attempt. It was the first manmade object to reach the surface of Mars. The orbiter continued operating until 22 August 1972. [6] [7] Mars 3 Orbiter and Lander: Mars 28 May 1971 2 December 1971 entered orbit/landed: 189 days (6 mo, 5 d) Mars 3 did not attain its ...
This is a list of all spacecraft landings on other planets and bodies in the Solar System, including soft landings and both intended and unintended hard impacts. The list includes orbiters that were intentionally crashed, but not orbiters which later crashed in an unplanned manner due to orbital decay .

“The spacecraft saw Uranus in conditions that only occur about 4% of the time.” An image of the planet Uranus taken by the NASA spacecraft Voyager 2 in 1986.
Mariner 2 (designated Mariner R-2) was launched on August 27, 1962, sending it on a 3½-month flight to Venus. The mission was a success, and Mariner 2 became the first spacecraft to have flown by another planet. On the way it measured for the first time the solar wind, a constant stream of charged particles flowing outward from the Sun.
