I selected none of these. They are busy enough without working on second stage recovery this year. Maybe 2016.
I think that they will try to do some crazy controlled re-entry attempts, without much hope for success, in order to gather as much data as possible.
Official request for an answer also sent on this too.....I honestly don't know as of right now.
I voted none of the above. 2nd stage reuse is years away, I think.
Second stage recovery/reuse in any shape or form? In 2014? Forget it.
So do you guys think there will be an attempt?
I put "Attempt Recovery". i don't think they will do any mods to 2nd stage such as legs or added TPS. But I think they will do some additional RCS test maneuvers, additional engine relights (3). I mean why not? On CRS fights, they have margin to "Play" with and maybe get some additional data on controlled reentry sequences.

On CRS fights, they have margin to "Play" with and maybe get some additional data on controlled reentry sequences.I selected "none of the above" because I think they already have too much on their plate. I do agree that they may experiment with reentry to collect some data, but I couldn't check the "return/recovery" option because I don't see anyway for a second stage to survive reentry without a heat shield. "Controlled" reentry still results in pieces too small to recover.I'm not a rocket scientist and I'm a newbie to the forum, so I could be completely full of it.

As for 2014 being too early, I voted that way but ... for Jason 3 and indeed for recovery of any second stage that was tasked with a two-burn mission profile (i.e. GTO) the first step of stage recovery would likely involve a third burn, i.e. a second restart much later in the mission. I could see SpaceX doing early trials of just that step in 2014, even if there wasn't sufficient residual propellant to send the stage immediately into the atmosphere.

? 162 voters voted for "None of these" equaling ~48%. However, 162 / 231 = ~70%. The poll is not calculating correctly...?
