Sad to see CNN news article title is 'SpaceX rocket lands, falls over' - did someone tell them it was a successful launch?
Quote from: Fr4nK on 04/14/2015 09:57 pmBased on common sense. You aim for the X or you aim for no lateral motion while landing somewhere on the barge. Bigger barge means more marginWrong and neither is it common sense . The rocket is not aiming for the barge, it is aiming for a spot on the ocean. The barge happens to be at the spot.

I'm not a nautical man, but is there any way to reliably anchor the barge - maybe using multiple anchors - to keep the barge from moving at all? Then the barge would truly be a stationary piece of ground.
Well, oil rigs don't use thrustmasters, and are instead anchored to the ocean floor. If this stage had been landing on something that was more like an oil rig than the current barge, then would this touchdown have had greater chances of success?Yes, a barge may be cheaper than an oil rig, but if you're going for reusability you may not want to skimp on this cost.
The barge is not going to be the primary landing site, it will be on land.

Here is what i would add to JRTI ship to help with tipping rocket. It would be folded down until the engine cut off. then spring up to act as a fence for the rocket. Sry for my poor drawing skills
Not the FAA's call but the air force's

The rocket has just to land rightAnd if the rocket is on the edge, those things will knock it over

Of course you can add some brain to it so you adjust depending on where it lands. Just need it to be strong and fast. (To prevent tipping)
