This is really tough to do. They will get it done.

The difficulty is exactly why I mentioned that accidents will happen.

I was just throwing out the possibility that maybe there is or will be some industrial espionage going on, and that the security now that we're in the realm of public industry might not be the same as what it was and is with NASA and the Air Force. And I was thinking more along the lines of possible sabotage by Russian interests, than say domestic competition between SpaceX and Orbital ATK, since the Russians stand to lose a good chunk of money to launches by domestic enterprises.

Just a theory...

Russia lost an ISS launch recently as well.

Seems that all scores are settled, then. If I'm sitting up there in the ISS I'm hoping they're done ****ing with each other now.

Friday is a key launch. Same vehicle as the Russian one that went haywire a month or so ago (Pegasus) for another ISS resupply mission. They have plenty of supplies up there normally, but they've lost two in a row and (I think) 3 of the last 4 at this point. If the one on Friday has issues, things may start getting dicey up there.

Preliminary conclusions are that a strut from a third-party supplier (unnamed) snapped well below certified load, causing a helium tank to roll around all over the place and eventually rupture the second stage LOX tank. Wouldn't want to be that supplier right now.

One kind of cool outcome - they determined that the Dragon capsule itself survived and could have been saved entirely if the software program had been written to deploy the parachutes upon rocket failure. They're building that in so that, in the future, it should be able to save itself if this were to happen again.

They're not committing to any particular time frame, but launches could resume as early as September.

These are just drawings, but it's fun to see the game plan visually.

Pretty amazing, but that looked a little hairy at the end. Engines looked like they were gimballing like crazy.

I agree. I definitely had some yaw in my seat watching the video. LMAO

They also have a long way to go before getting too excited about this. It takes a lot more effort to slow a rocket down from an orbital launch.

Elon is not impressed.
