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.
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 ...
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).
He said the Senate currently is budgeting $200 million for ongoing development of the Mars Sample Return mission in NASA's fiscal 2025 budget. The House number is $600 million.
The head of NASA's Jet Propulsion Laboratory warns that jobs at the lab will be in jeopardy if proposed funding cuts for the Mars Sample Return mission go through.
SCIM was a sample return mission that would have used a free-return trajectory and aerogel to capture Mars dust and return it to Earth [17] (see also: the Stardust mission). MARVEL was an orbiter that would have searched for volcanism as well as analyzed various components of the Mars atmosphere. [17]
