The Mars 2 was an uncrewed space probe of the Mars program, a series of uncrewed Mars landers and orbiters launched by the Soviet Union beginning 19 May 1971. The Mars 2 and Mars 3 missions consisted of identical spacecraft, each with an orbiter and an attached lander.

The following table is a list of successful and unsuccessful Mars landers. As of 2022, 21 lander missions and 8 sub-landers (Rovers and Penetrators) attempted to land on Mars. Of 21 landers, the Curiosity rover and Perseverance rover are currently in operation on Mars. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21.

The Beagle 2 was an inoperative British Mars lander that was transported by the European Space Agency's 2003 Mars Express mission. It was intended to conduct an astrobiology mission that would have looked for evidence of past life on Mars.

Mars 2 released the descent module (71-045D) 4.5 hours before reaching Mars on 27 November 1971. The descent module entered the martian atmosphere at roughly 6.0 km/s at a steeper angle than planned. The descent system malfunctioned and the lander crashed at 45 deg S, 313 deg W, delivering the Soviet Union coat of arms to the surface.

May 1, 2015 · The Mars 2 and 3 landers carried a small (21.5 x 16 x 6 cm) walking robot called PROP-M. The robot had a mass of 4.5 kg and was tethered to the lander by a cable for direct communication. The rover was designed to "walk" on a pair of …

Jan 14, 2023 · The Mars 2 lander became the first man-made object to reach the surface of Mars. The probes consisted of an orbiter section and a landing capsule. They were built by NPO Lavochkin.

Nov 12, 2024 · Mars 2, a lander built by the former Soviet Union, has the double-edged distinction of being the first human-built object ever to touch down on the Red Planet.

Aug 20, 2020 · Viking 2 entered orbit around Mars on July 25 and the lander made its touchdown in Utopia Planitia on Sept. 3. Launches of the Viking spacecraft: Viking 1, left, and Viking 2. Both orbiters and landers far exceeded their expected 90-day lifetimes in their scientific exploration of Mars, vastly increasing our knowledge of the planet, its ...

Two weeks later, on 27 November 1971, the Mars 2 (consisting of an orbiter and lander) also arrived to Mars. Late to that milestone, the Mars 2 mission had another, bigger objective, to put an unmanned rover on the surface of the red planet!

Nov 27, 2019 · An on-board computer malfunction and inaccurate data due to the dust, caused Mars 2’s lander to enter the atmosphere incorrectly. After entering the atmosphere at approximately 6 km/s, the descent system on the module malfunctioned.
