Beagle 2 Official Inquiry Released
smasch writes "The ESA/UK Commission of Inquiry into Beagle 2 has released their
report (PDF) on why the Mars lander Beagle 2 failed. While the report does not name a single cause for the failure, it does name several problems including the lack of funding, lack of margin in the design, and treating Beagle 2 as a scientific instrument rather than as a spacecraft. The report also made nineteen recommendations to prevent these sorts of failures on future missions. We have previously mentioned the Beagle 2 failure, although the official report was not released to the public at that time.
The original story from MarsToday.com is available here."
3 landers = 3 times the parachutes, external equipment, communications systems. With that kind of weigh allowance, we could do a lot more. Beagle 2 was static - with 3 times the weight allowance, we could have a rover.
Not everything will run perfectly - NASA dropped a fragile disc into the desert at 500m/s last year if you remember. But we can't afford to build double redundancy into already expensive spacecraft.
