A Mars sample-return (MSR) mission is a proposed mission to collect rock and dust samples on Mars and return them to Earth. [1] Such a mission would allow more extensive analysis than that allowed by onboard sensors. [2]
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]
In the summer of 2001, the Jet Propulsion Laboratory (JPL) requested mission concepts and proposals from industry-led teams (Boeing, Lockheed Martin, and TRW). [17] The science requirements included at least 500 grams (18 oz) of samples, rover mobility to obtain samples at least 1 kilometre (0.62 mi) from the landing spot, and drilling to obtain one sample from a depth of 2 metres (6 ft 7 in).
Nelson said both options involve cleaning Martian dust from the tubes on the planet surface instead of on the return vehicle, and using one of the spare arms on the Mars Perseverance rover to ...
In April, after an independent review found “near zero probability” of Mars Sample Return making its proposed 2028 launch date, NASA put out a request for alternative proposals to all of its ...
NASA is seeking a cheaper, simpler approach to one of its top science priorities in the midst of a budget crunch - retrieving precious soil samples collected on Mars and flying them back to Earth ...
The Sample Collection for Investigation of Mars (SCIM) is a mission concept for a Mars air and dust sample return. It was a semi-finalist at the Mars Scout Program along with four other missions in December 2002. [2] [3] The SCIM mission would be designed to skim through the Mars atmosphere without landing or entering orbit. [1]
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.
