SpaceX Sticks the Landing!

With the tanks nearly empty and all the engine mass clear at the bottom, it really shouldn't be top heavy at all. I bet the center of mass is no more than 25 feet above the ground. Even without a leg locked in, it took a lot longer to tip than it should have...you can hear that RCS thruster screaming its head off up top, working against the tipping. Between the RCS (however long that can last after landing) and the bottom-heaviness of the thing...probably take some pretty substantial wind and swells to actually push it over.

Why the barge landing when the land one succeeded?

Nature of the launch. Depends on the amount of energy involved in getting to whichever orbit, and the amount of fuel needed to actually travel all the way back to the launch site. For example, the launch last year out to L1 (beyond the orbit of the moon) had no chance of a landing. They needed every drop of performance from the launcher to get into deep space. This launch was for a science mission, and used a polar orbit. So, going south-north instead of east- west like from Florida. Which is why it launched from Vandenberg AFB. ..nothing but water under it going south. Also, this was an older rocket, as opposed to the "Full thrust" model they're using currently, with uprated engines and more fuel. In addition to all of this, there was no FAA authorization to land at Vandenberg. Endangered species nesting there, I think.

Not all launches are going to be recoverable from land, due to physics. Some are going to require the drone ships going forward.

Thanks for that.

Nah

Epic troll on Ex and Phil by Uber. I'm back in the club but I'm it's token black. It produced another "FREE JIMMYZ" thread and some hilarity in chat earlier today.

spaceX blew up on launch pad while getting fuel. musk in typical fashion said it was an "anomoly"

Bad news. Lots of hardware on the pad that is extremely expensive (and not fast) to replace. Going to screw up their entire launch schedule. Boeing might beat them to the ISS with a manned ship after all.

i know it didn't need the emergency escape mechanism, but don't they have that? seems like a perfect way to have saved some cargo
