Can NASA Return Mars Samples to Earth? New Audit Raises Doubts

Space.com writes that NASA's plan to return samples from Mars to the earth "is facing major challenges, according to a new report. "Design, cost and scheduling are all significant obstacles, an audit report of NASA's Mars Sample Return (MSR) Program by the agency's Office of Inspector General (OIG) finds..."It involves landing on Mars to collect samples taken by the Perseverance rover and launching those samples to rendezvous with an orbiter, which will haul them to Earth. Perseverance is already on Mars, snagging and storing samples. But the program still needs to build a Sample Retrieval Lander and an Earth Return Orbiter, the latter being developed and funded by the European Space Agency. The Mars Sample Return program is one of the most technically complex, operationally demanding and ambitious robotic science missions ever undertaken by NASA, according to the OIG report. The report notes design, architecture and schedule issues with the Capture Containment and Return System. These design issues resulted in adding about $200 million to the budget and one year of lost schedule... There is concern that, due to the number and significance of cost increase indicators so far, the $7.4 billion estimate is "premature and may be insufficient," the report finds. Now, the complexity... could drive costs to between $8 billion to $11 billion, the OIG report notes, citing a September 2023 Independent Review Board report. Notably, a July 2020 estimate listed costs of $2.5 to $3 billion. These new figures indicate significant financial challenges and uncertainties... Issues include inflation, supply chain problems and increases in funding requests for specific program components.
