rick, thank you. jon: red bull gives you wings, but will they give you a parachute? a privately-owned spacecraft lost one of its nine engines shortly after lifting off sunday night. nasa says the rocket still was able to make it into space, though it is unclear what caused that engine to fail in the first place. let's talk about it with tom jones, a former nasa astronaut and the author of "planetology." e guess this thing has nine engines, one failed pretty spectacularly. do we know what it was? >> hi, jon. i think no one really knows the cause yet, but they got good data down from the engines. one of the nine had a pressure loss is what spacex is saying, and apparently it blew debris off the side of the product.
