Re: SpaceX's Grasshopper

We still don't know if they can land it accurately, as in where they want to. Until they can do fairly pinpoint location targeting the FAA is going to be pretty shy about letting them bring the stage back to the coast of Florida.

Regardless, the next two flights won't be doing landing tests, the crs-4 flight after those will have a "low chance of success" for landing per SpaceX. The two flights after that they hope to try landing on a "solid surface". Read into that statement what you will.

Re: SpaceX's Grasshopper

I assume this refers to some kind of water platform, I've seen such mentioned somewhere by SpaceX IIRC. Although I find the idea of landing on a floating platform vertically a little bit crazier than landing on land, so if that's what it means it is kinda cooler than a land landing.

Actually, a floating platform makes a great deal more sense, especially if they have control of the descending stage (which they probably do). SpaceX has so far demonstrated an intense hatred of red-tape, and they could easily get around FAA obstructions by simply towing their landing pad out to sea on a barge and then not giving a fuck what happens after that. It's the same thing they did with the Dragon and the Falcon 9 before it: once they've proven the concept, it becomes politically infeasible to argue against letting them try it for real.

Re: SpaceX's Grasshopper

Yeah. I am just irrationally wary of withstanding the weight of a rocket plus the pressure of the engines without having a solid ground underneath you. It's as crazy as the Zenit launches. It's not actually that big of a feat, but when I first heard about it I thought "wait, this is possible?"

By the way, if SpaceX have full control over landing location, why haven't they been able to get a camera crew near the spot to record the whole thing?

Re: SpaceX's Grasshopper

This was only the 3rd landing attempt. I am guessing they are being cautious about putting people in harm's way.

People on a camera crew? That's so last decade.

Just put Google Glass on a shark and you're done.

There is an image of a barge toward the end.

The barge is a stock photo used for the article.

Nice bang for Grasshopper 2 (which they called the Dev1 vehicle).

Re: SpaceX's Grasshopper

Things do fail from time to time--but...

Why do I have this feeling that some executive in a smoke filled room just got a call from a blue-suited spook?

"It's done."

All it took to bring an Ariane down was a rag left in some plumbing...

^Unlikely. If you're going to sabotage something, go for the operational vehicle with the paying payload. Not the test article that's main intention is to find failure modes. (FOUND ONE!)

Yeah. ULA has to be stipud to sabotage stress testing of a downscaled experimental version of a vehicle that was going to blow up sooner or later anyway. And after the test site was moved to avoid debris raining over people, suggesting SpaceX were expecting it.

Re: SpaceX's Grasshopper

The test site wasn't moved. They've always done flight tests in McGregor, TX. It also wasn't a "downscaled version". That was a full size F9 first stage. It just had only 3 engines instead of 9.

Hmmm, do you suppose people would drive better if cars were outfitted with range safety charges?
