The commercial SpaceX rocket venture has launched Dragon cargo capsules to the International Space Station three times in the past year, and every time there's been a problem. Should NASA be upset?
The fact that glitches have cropped up — and have been solved, with no impact on the multimillion-dollar cargo resupply missions — isn't a black mark against the California-based company. Rather, it's a sign that the designs for SpaceX's Dragon capsule and Falcon 9 are resilient in the face of the inevitable glitches associated with spaceflight. It's also a sign of things to come.
