Lessons Learned – The Risk Reduction From ?Two-fers? (Multiple Sister Spacecraft) May Outweigh the Incremental Cost (2002)
Year: 2004
Abstract: Abstract:
NASA elected at the end of MER Phase A to build a second Mars Exploration Rover at an estimated cost of $243 million. In addition to potentially doubling science return from Mars and mitigating the program impact were a rover to fail, this "two-fer" approach proved helpful in controlling development risks. Consider the benefits to system development and I&T that may accrue from building a "sister" spacecraft and from maintaining multiple testbeds.
