"Critical Flaws Uncovered in NASA's Mars Sample Return Plans, Independent Reviewers Say"

An independent review of NASA's Mars Sample Return mission has found that the program is unworkable in its current form, with unrealistic budget and schedule expectations. The earliest launch opportunity would be in 2030 with a budget of $8 billion to $11 billion, far exceeding the original $4.4 billion budget. Concerns have been raised that the ballooning cost of the mission could impact funding for other science missions. The mission involves a Sample Retriever Lander, Perseverance rover, Mars Ascent Vehicle, and an Earth return orbiter to bring back samples from Mars.
