]Off topic, but wouldn't it be nice if they could fit that solar sail spacecraft, or anything other payload, with an escape rocket, like they do with manned capsules, so it doesn't get lost as often as the rocket does? (Shroud serves as heat shield, add parachute. I know there a lot of issues like reduced payload capacity and increased vehicle complexity, but it's just a thought.)

In other words, shut down and fall to your doom. No explosive termination systems in the F1.Thanks for clarifying that for me.Doesn't range safety at the Cape require an active destruct system?

Rocket Science is really hard.Cut them some slack.
spacex says the stages failed to separate.
Great news that the first stage performed as expected, I know today is still a disappointment but at least there's that.
But was not stage seperation one of the things that doomed flight 2? Is stage seperation very hard?
Elon's sent an e-mail:It was obviously a big disappointment not to reach orbit on this flight. On the plus side, the flight of our first stage, with the new Merlin 1C engine that will be used in Falcon 9, was picture perfect. Unfortunately, a problem occurred with stage separation, causing the stages to be held together. This is under investigation and I will send out a note as soon as we understand exactly what happened. The most important message I’d like to send right now is that SpaceX will not skip a beat in execution going forward. We have flight four of Falcon 1 almost ready for flight and flight five right behind that. I have also given the go ahead to begin fabrication of flight six. Falcon 9 development will also continue unabated, taking into account the lessons learned with Falcon 1. We have made great progress this past week with the successful nine engine firing.As a precautionary measure to guard against the possibility of flight 3 not reaching orbit, SpaceX recently accepted a significant investment. Combined with our existing cash reserves, that ensures we will have more than sufficient funding on hand to continue launching Falcon 1 and develop Falcon 9 and Dragon. There should be absolutely zero question that SpaceX will prevail in reaching orbit and demonstrating reliable space transport. For my part, I will never give up and I mean never. Thanks for your hard work and now on to flight four.Elon
Chris, can you e-mail Elon back with our best wishes?
I honestly wonder if they'll go look for the vehicle. Could be very interesting evidence in there on this non-sep event.
Having said that, I wouldn't expect much to be left of that hardware after igniting the 2nd stage engine into a still-attached 1st stage/interstage.
