SpaceX Releases Video of Falcon Rocket's Splashdown 49
First time accepted submitter cowdung (702933) writes In spite of Elon Musk's characterization of the landing as a KABOOM event. Judging by this video SpaceX has managed to land the first stage rocket booster nicely on the ocean after their Orbcomm launch on July 14th. It seems we're one step closer to a landing on dry land. Both this and the previous landing seem to have gone well.
Hopefully the next landing test camera has something to deice the camera lens.

'some middle manager will whine endlessly about this sort of experimentation.'
And will be sacked by the board.
Around 60% of the total cost of the rocket is the first stage.
The aim is to have this reusable in a few hours turnaround time.
If this works, savings per launch are tens of millions of dollars, even if it only works half the time.
If the second stage can be made reusable as well, going from $60M price to launch 10 tons to LEO to half of that _and_ making more profit per launch is quite possible.
Re:What flyout and back plan? (Score:4, Informative)
At the point where the booster separates, it has burned most of its fuel, and weighs a fraction as much as it did at launch. As a result, it requires far less fuel to kill its velocity and put itself on a trajectory back towards the launch site than the initial launch did (far less mass to accelerate on the return trip).
It does still require some extra fuel (hence why they talk about having to use expendable Falcon 9s for missions that are close to the max payload capacity until they can get Falcon Heavy flying), but for small to medium sized cargoes, they have the fuel to burn.

For starters, NOBODY has taken anything as large as the first stage to space and landed it under power on earth. This is absolutely a first.
Secondly, they have the cheapest launches going. Why? Because they automated heavily. That has not been done.
Thirdly, no escape system has been a pusher system ever before (though boeing is attempting it as well).
Fourth, no capsule has landed under power on earth. If he succeeds at that, it will be a first.
Fifth. nobody has successfully launched a rocket with 28 engines. If Falcon heavy succeeds, it will be a first.
Sixth, nobody has built a full-flow staged combustion engine using methane. SpaceX is working on just that, with raptor.
Now, do not get me wrong. I support NASA, as does most ppl from SpaceX. BUT, to claim that SpaceX is not doing anything innovative, is just as wrong as those that knock NASA.
