It blew up. :(

Actually, it looks more like it simply buckled, structurally. Something happened near the nose...looks like atmosphere got in somehow and just crumpled it. The whole top of the first stage is dominated by a lox tank, and that stuff was gassing off like crazy...engines seemed to be running fine, even as the rest of the booster was being shredded...

God what shitty luck. That's three cargo missions to the Station lost in like 6 months. Orbital Scienes, Roscosmos, and now SpaceX.

Learning curve. These rockets are so complicated and difficult to manufacture that it's a miracle more don't fail.

Pretty much. Statistically about 5% of launches fail.

This just a weird failure, though. "Overpressure event" in the 2nd stage LOX tank...but the second stage hadn't finished its startup process as the first stage was still burning...one guy was saying that the neutral gas they use to pressurize the the LOX tank as it drains could have over pressured the whole thing if a valve stuck...

Heartbreaking setback. I'll be amazed if they fly again this year. Gives their competitors the initiative.

I'm thinking this was probably a manufacturing defect. Might be unavoidable in something so complex.

i don't know why we don't seriously consider non-rocket based methods of getting in to space. even if just for cargo. we could develop a shuttle-like vehicle to be permenantly docked at the ISS to capture cargo as it enters LEO and begin doing all the crazy shit we've dreamed of like orbital shipywards, missions that don't require massive fuel payloads just to get off the ground etc.

i'm highly skeptical of SSRI spaceplanes ever being a thing. even assuming SABRE is viable, how useful will it be for bringing payloads in to orbit? i feel like an engine that has to walk such a thin line under so many different variables leaves little room for excess vehicle weight a la cargo holds. i know it's supposed to work with skylon but that thing looks like a complete pipedream.

no, i'm talking mass accelerators.
