NASA Halts Mars Sample Return Mission for Assessment
NASA is pausing its Mars Sample Return program (MSR) to reassess the mission after an independent review board deemed the original plan unrealistic. The program has faced mounting costs and delays, prompting NASA to consider alternative architectures. The Senate Appropriations subcommittee allocated $300 million towards MSR but requested a year-by-year funding profile. The mission's full lifecycle cost is estimated to range between $8 billion and $11 billion. NASA is exploring options such as launching the lander and orbiter on separate dates and reducing the quantity of samples returned. Despite the challenges, MSR remains a crucial part of NASA's plans for Mars exploration and the search for signs of ancient life on the planet.
