NASA is dramatically overhauling its mission to bring pieces of Mars back to Earth, operating under bare-bones budgets to seek proposals for a faster and cheaper mission architecture.
The estimated cost of the Mars Sample Return mission has doubled from $4.4 billion to between $8.4 billion and $10.9 billion, with samples expected to arrive on Earth in 2040.
NASA administrator Bill Nelson expressed dissatisfaction with the 2040 return date and the $11 billion price tag of the Mars Sample Return mission.
