NASA astronauts will have to wait until another day to launch to orbit in the Boeing Starliner spacecraft. The planned launch was called off Monday night because of a problem in the Atlas V rocket that was to send them to space.
Engineers will work through the night to assess whether the two astronauts, Butch Wilmore and Suni Williams, can get back on the launchpad on Tuesday, or if repairs will be needed that could delay the flight by at least several days.
Absolutely. But every vehicle platform scrubs, so there's not a ton of point in speculating about the reliability of a brand-new launch vehicle based on one scrub. There's a huge gulf between Soyuz and the Space Shuttle.
