Right. And if they are launched serially, you've got a chance to correct mistakes in the previous launches. Odds of success increase with every launch.
2x — failed to deploy, mission lost
4x — early operation error, 6mo lifetime
3x — lower performance, 3 year lifetime
1x — mission successful, 10 year lifetime
…do we get a better deal building them with larger faults, at a lower cost?
A lot of expense is in developing technologies, assembly tooling, and test rigs — all of which is easier if we don’t need them to be as assured because only 1 in 10 needs to succeed.
