The Soviet Union considered a Mars sample-return mission, Mars 5NM, in 1975 but it was cancelled due to the repeated failures of the N1 rocket that would have launched it. Another sample-return mission, Mars 5M (Mars-79), planned for 1979, was cancelled due to complexity and technical problems. [14]
The sample retrieval mission involves launching a 5-solar array sample return lander in 2028 with the Mars Ascent Vehicle and two sample recovery helicopters as a backup for Perseverance. The SRL lander is about the size of an average two-car garage weighing ~3,375 kg (7,441 lb); tentatively planned to be 7.7 m (25 ft) wide and 2.1 m (6.9 ft ...
The ESA has also considered a sample return mission, one of the latest known as Martian Moon Sample Return or MMSR, and it may use heritage from an asteroid sample return mission. [57] Osiris-Rex 2 was a proposal to make OR a double mission, with the other one collecting samples from the two Mars moons. [58]
“Mars Sample Return will be one of the most complex missions NASA has ever undertaken. The bottom line is, an $11 billion budget is too expensive, and a 2040 return date is too far away ...
Later, other sample-return missions failed: Kosmos 300 and Kosmos 305 in 1969, Luna E-8-5 No. 405 in 1970, Luna E-8-5M No. 412 in 1975 had unsuccessful launches, and Luna 18 in 1971 and Luna 23 in 1974 had unsuccessful landings on the Moon. [13] In 1970, the Soviet Union planned for a 1975 first Mars sample-return mission in the Mars 5NM project.
The study suggests leveraging Rocket Lab’s vertically integrated technologies to retrieve samples from the Red Planet for the first time as part of NASA’s Mars Sample Return Program.
Tianwen-3 (Chinese: 天问三号) is a planned Mars sample-return mission by China which would send two spacecraft (an orbiter/Earth-returner and a lander/ascent-vehicle) via two separate launches to Mars. Together, the two spacecraft will seek to obtain samples of Martian rocks and soil and then return the cached samples to Earth. [1]
The move to redesign the mars sample return strategy comes after a NASA-commissioned independent review concluded last September that the program was hindered by "unrealistic budget and schedule ...
