An exploding budget and an unraveling schedule spell disappointment for NASA's mission to learn more about Mars's history.

The company has outlined its proposed architecture to return martian rock and dust samples to Earth for research.

NASA announced Tuesday that it is exploring two options to move forward with its mission to return samples from Mars at a lower cost.

NASA hopes a revised plan will get Mars samples back to Earth faster and cost less than the agency's original plan.

Previously, the Mars Sample Return mission had been estimated to cost around 11 billion dollars and would not return a sample until the 2040's, noted Nelson, who said a re-evaluation of the mission had to be done because "this thing had gotten out of control."

NASA announced Tuesday it had narrowed down to two options the reworked Mars Sample Return mission aiming for a cheaper and quicker completion than the version that had been killed last year.

NASA has announced revisions to its Mars Sample Return Program, aiming to simplify the mission, reduce costs, and expedite the timeline for bringing Martian soil samples to Earth. The initial plan, which involved multiple spacecraft, is being restructured to address technical and financial challenges.

NASA has announced potential plans to recover rock samples from Mars. Scientists aim to investigate whether there is extraterrestrial life on the Red Planet. Bringing back the Perseverance rover, which has been collecting materials from the bottom of a Martian lake since 2021,
