MOJAVE DESERT, CA - Right now there are more questions than answers about the Virgin Galactic spacecraft that crashed. The SpaceShipTwo broke up in mid-air during a test flight on Friday. One of the pilots, Michael Alsbury, was killed. Another was injured.

The U.S. National Transportation Safety Board team has completed its first round of the investigation into the SpaceShipTwo accident, but they haven't gotten all their answers yet. Officials say it'll take four to seven more days to go through the wreckage.

"We're going to learn from what went wrong, discover how we can improve safety and performance and then move forward together," said Richard Branson, founder of the Virgin Group.

All-in-all, it's been a bad week for space travel. The SpaceShipTwo accident happened just days after NASA's unmanned "Antares" rocket exploded seconds after lift off.

Now there's a lot of doubt as to whether or not commercial space travel is even safe. Around 800 tickets, which cost $250,000 have already been booked for planned spaceflights. Stars like Tom Hanks and Lady Gaga have reportedly bought some. But with so many questions lingering over the accident, the space industry is just left asking now what.
