NASA lost a lunar spacecraft one day after launch. A new report details what went wrong

Summary

NASA's Lunar Trailblazer mission failed due to software errors and inadequate testing. A review panel report revealed the cause, highlighting the need for better risk management in lower-cost missions. The incident prompted extra scrutiny for future missions.

Key Takeaways

1. The Lunar Trailblazer mission failed due to a software error that misdirected the solar panels and other onboard fault management issues.
2. Lower-cost NASA missions, while riskier, should still prioritize mitigated and understood risks over "foolish risk."
3. The Lunar Trailblazer failure prompted NASA to give extra scrutiny to the Escapade mission, demonstrating a learning process.
