NASA to choose Mars sample return method by late 2026 after budget review
NASA will evaluate two options for returning soil samples from Mars, with a decision expected in late 2026. The program was paused after a review revealed costs could reach $11 billion, significantly over budget. The first option is a "sky crane" method, similar to previous rover landings. The second involves collaboration with commercial space companies like SpaceX and Blue Origin. Both methods will use a smaller Mars Ascent Vehicle to transport samples to orbit. Costs for the new options are lower, estimated between $5.8 billion and $7.7 billion. The samples are expected to return to Earth between 2035 and 2039, aiding research on potential life and safety for future missions.
