SpaceX is switching over to a different space ship after an incident at the company's Boca Chica, Texas test site. Yesterday, CEO Elon Musk tweeted that the company is switching from the MK1 to the MK3 vehicle. The top of the MK1 blew off during yesterday's pressure test. The company says the outcome was not a surprise nor a serious setback. There are no reports of injuries in the launch pad mishap.
