Perhaps XSS-11 will be more successful. And I'd assume that a DART

the
DART mission plan didn't have a whole lot of contingency margin -
"success oriented planning" strikes again, I see.


According to Spaceflightnow reports, the XSS-11
mission is costing $80 million for a one year+
mission (including launch), $30 million less than
NASA's XSS-11 cost for a one day mission. Both
missions were designed to test rendezvous
techniques.
