NASA is exploring two potential strategies to bring Mars samples back to Earth, aiming to simplify and reduce the cost of the mission.
The Perseverance rover has been collecting rocks and dust since it landed on Mars in February 2021.

Returning those samples, however, presents significant challenges.
The original mission plan, delayed until 2040, is estimated to cost up to $11 billion.
To address these hurdles, NASA is considering two more efficient options.
One approach would use the same landing technology that delivered the Perseverance and Curiosity rovers to Mars.
The second strategy involves working with industry partners to develop a “heavy-lift vehicle” lander capable of handling the mission.
NASA Administrator Bill Nelson says the agency plans to decide on a new path by the second half of 2026.
