NASA outlines cost-effective strategies for Mars sample return mission

NASA has proposed new, cost-effective options for its Mars Sample Return mission, which had an estimated cost of $11 billion and a delayed timeline. The agency aims to bring samples back by 2035 instead of 2040. Two main options were presented. One involves using a proven sky crane method for landing, potentially reducing costs to between $6.6 billion and $7.7 billion. The other option would use a commercial "heavy lander," which could lower costs to $5.8 billion to $7.1 billion. Both options include redesigning the lander and Mars Ascent Vehicle to be smaller and lighter. NASA plans to analyze these options over the next 18 months.
