NASA s Mars sample return program faces significant cost overruns

Mondo Science Updated on 2024-03-03

The costs associated with space exploration seem quite high. NASA and financial regulators closely monitor progress and feasibility through audits. Supervisory authorities keep a close eye on whether taxpayers' money is being used. They look at whether specific scientific achievements that can bring prosperity to humanity are justified.

A landmark NASA program to bring Martian rock samples back to Earth is heading toward the financial black hole of Mars exploration.

In a scathing new audit, NASA's Office of the Inspector General (OIG) slammed the Mars Sample Return (MSR) project for a lack of financial planning, delayed design, and what they called "initial over-optimism." The estimated cost of the mission has steadily climbed and is now poised to rival some of the agency's most expensive efforts.

Earlier, NASA had to cancel the OSAM-1 project due to technical obstacles, increased costs, and a change in schedule. NASA's inspector general's audit report appears to have played a crucial role in this decision.

The agency released another report on Feb. 28 highlighting the fundamental problems NASA has historically faced in managing large programs — with MSR being the latest victim.

The audit paints a grim picture of a troubled mission. As of June 2023, the MSR project is informally set at a staggering $7.4 billion cost. While lower than the independent review's estimate of $8 billion to $11 billion, the OIG said even this lower figure could be underestimated.

Delays have been plaguing a key part of the program – the Capture, Containment, and Return System (CCRS). The mechanism, designed by NASA, will grab containers of samples launched into orbit around Mars, sterilize them, and seal them for return to Earth. It was supposed to complete a preliminary design review by the end of 2022, but due to technical hurdles, this milestone was not completed until December 2023. OIG said the delays could weaken the entire project, leading to significant changes to the launch schedule.

The report unequivocally accuses NASA of poor early planning and tends to underestimate the reality of large missions. While factors such as the pandemic and chain issues have led to inflated costs, the audit slammed NASA for not fully grasping the internal issues. This echoes NASA's previous probes, which suffered staggering cost overruns.

MSR projects find themselves at a crossroads of finance and design. The recently announced agreement to fund spending bills, including NASA's budget, is promising. Now, Congress is scrambling to pass a key appropriations bill by March 8 that will finally clarify NASA's budget for this year.

The White House is also expected to release its fiscal year 2025 budget proposal on March 11. This, along with the looming architectural reassessment, will be critical in determining the ultimate path forward for NASA's Martian dream.
