Coming up on a OA burn, that will decrease Atlantis' altitude. So from now, til Moon landings, NO human beeing will venture out that far away (300 nm) from planet earth,...
Er? Unless I've missed something, the apogee will still be around HST altitude, won't it? It's just lowering one side.

I don't have the flight plan in front of me, but I suspect there will be a burn to circularize the orbit at the lower altitude.
ETA: Belay my last, the orbit will remain elipitical as per PAO.

No, they will de-orbit from the resulting orbit after this burn.

First I'd like to thank Chris and everybody @ NSF for the excellent job of following this awesome mission.
I'd like to ask you people, if HST deploy was today, why does landing takes place three days later?? I see in the NASA TV Wednesday schedule activities such as PAO events, ISS/STS-125 communication and free duty time...couldn't they just focus now on late TPS inspections and deorbit preparations for landing tomorrow or Thursday?? I know that free duty time is compulsory and there are loads of things to do before deorbit but isn't safer to bring them back home as soon as possible???

Yeah, just after I posted that, the PAO made his comments re: the orbit. I need to be more patient.

Good config for the burn. 1 minute away.

Good burn, no trim required. Interesting visuals at shutdown. (And ignition, too.)
Orbit now 305 x 160 nautical miles.

Anyone know how high the Shuttle could theoretically go if called upon ?

IIRC the HST is at pretty much the max altitude for the fuel and mission. If it went up just for an alititude hoorah I guess it could go higher with enough cryo to get it back.

Depends on many factors - main ones are: payload mass, inclination, perigee, rendez-vous requirements. Number of crew are a factor as well as mission duration.
400 - 500 nm is possible @ 28 deg, minimal payload, and stay time, w/o rendez-vous rqmts.
