Near the launch site? That seems a little ambitious, and expensive. Are they planning on doing a u-turn in high atmo? The energy required would be massive.

Near the launch site? That seems a little ambitious, and expensive. Are they planning on doing a u-turn in high atmo? The energy required would be massive. Or are they planning on doing an orbit of some sort? Doesn't the falcon heavy animation show the stages all landing at a different facility? Given that most every launch will point in a different direction from the launch site (different inclinations), boats would seem the best option. They could then haul the stage back to base by sea.

Yes, it's called a boostback burn, and it's been a part of every landing attempt thus far. The first stage has burned so much fuel at the stage separation that it takes much less to return it home than it did to accelerate it. You are correct though that it limits the payload capacity of the platform. I believe the Falcon Heavy animation shows the rockets returning to the launch site.

  This launch was/is going to be the first one without a boost back. Because of DSCOVR's mass and destination (Earth-Sun L1 point), there isn't enough fuel to make a boost back burn. That's why the barge is ~650 km off the coast[0] instead of the 350 km it was for CRS-5[1].

  Also, aren't they planning to launch from California and/or Texas in the future?

    They've already launched from California, at Vandenberg AFB. They've begun constructing a drone ship for landing future rockets launched from Vandenberg, named Of Course I Still Love You (the one currently in use for KSC launches is called Just Read the Instructions). And yes, they are currently constructing a new spaceport in Texas near Brownsville at the far southeastern corner of the state. Completion and first launches are anticipated in 2016. I'd guess they might use the current drone ship for landings from that one as well, but a lot can change in 2+ years so we'll have to see.

More info here: http://www.reddit.com/r/spacex/comments/2kghua/falcon9r_boostback_question/ http://www.reddit.com/r/spacex/comments/2kghua/falcon9r_boos... It looks like they indeed perform a u-turn, with the proviso that some of the return is accomplished by pushing higher, increasing orbital period, and waiting for the earth to rotate underneath.

I believe that the Falcon Heavy animation showed the stages returning to the launch facility. SpaceX's primary goals with reusable stages are reduced cost and reduced time to refurbish, and landing at the launch site is a big part of that.
