The milestones of STS-132 Space Shuttle Atlantis launch (reverse order) – See the mission details and more photos in my STS-132 Space Shuttle Atlantis post

~ 19:29:54 GMT @ T+09:45 – Nominal MECO, OMS-1 not required. With a direct insertion ascent, the main engines are burned slightly longer to achieve the desired apogee altitude, such that an OMS-1 maneuver (which would supply the additional thrust needed to reach orbit) is not required.

– 19:28:38 GMT @ T+08:29 – Zero Thrust.

– 19:28:32 GMT @ T+08:23 – Main Engine Cut-off (MECO). Atlantis has reach the planned orbit and is schedule to dock with the International Space Station on Flight Day 3.

– 19:27:49 GMT @ T+07:40 – Negative Istres.

– 19:27:28 GMT @ T+07:19 – Negative Moron.

– 19:26:36 GMT @ T+06:27 – Press to MECO and Single Engine Zaragoza 104 – Atlantis can now reach planned orbit in case of a single SSME failure and the Zaragoza TAL site on a single engine at 104.5% throttle.

– 19:25:37 GMT @ T+05:28 – Single Engine OPS-3 – Atlantis could now reach the designated TAL site with a single engine at Full Power Level (FPL), i.e 109% throttle, should two of the SSME‘s fail (the OPS-3 software mode will be used for re-entry) – Prior to this point, the loss of two engines requires contingency abort procedures and OPS 6 software.

– 19:24:51 GMT @ T+04:42 – Press to ATO select Zaragoza – Atlantis could now reach a safe orbit (circular / 194.5 km) with two Space Shuttle Main Engines (SSME) throttled at Typical Mission Power Level (104.5%) in case of a single SSME failure. Should one of the engines fail the crew could execute the Abort To Orbit (ATO) maneuver (in case of TAL abort, the landing facility in Zaragoza would be used).

– 19:24:04 GMT @ T+03:55 – Negative Return – Atlantis has used too much fuel and is traveling too fast (8,526 km/h), too high (87.7 km) and is too far (147.6 km) to return to the Shuttle Landing Facility (SLF) at the Kennedy Space Center (KSC) for a potential Return To Launch Site (RTLS) abort.

19:23:52 GMT @ T+02:43 – 2 engine Istres. Atlantis can now reach the Transoceanic Abort Landing (TAL) site in Istres in the case of a single engine failure.

19:22:42 GMT @ T+02:33 – 2 engine Zaragoza. Atlantis can now reach the TAL site in Zaragoza in the case of a single engine failure.

19:22:38 GMT @ T+02:29 – 2 engine Moron. Atlantis can now reach the TAL site in Moron in the case of a single engine failure.

– 19:22:23 GMT @ T+02:14 – Orbital Maneuvering System (OMS) assist.

– 19:22:13 GMT @ T+02:04Solid Rocket Booster (SRB) separation. Atlantis is at the altitude of 47.18 km, 44.57 km down range from the KSC, traveling at 5 022.7 km/h (Mach 4.1).

– 19:21:09 GMT @ T+01:00 – Max-Q (the point of the greatest dynamic pressure).

– 19:20:54 GMT @ T+00:45 –Throttle up back to 104.5% engine power level.

– 19:20:52 GMT @ T+00:43 – Mach 1.

– 19:20:42 GMT @ T+00:33 – Throttle down from 104.5% to 72.0% engine power level at Mach 0.9.

– 19:20:27 GMT @ T+00:18 – Roll maneuver finished.

– 19:20:20 GMT @ T+00:11 – Start the roll program.

– 19:20:00 GMT @ T-00:09 – The hydrogen burn-off system begins to eliminate free hydrogen exhausted into the main engine nozzles during the start sequence to prevent small, but potentially dangerous, explosions when the main engines ignite.

– 19:19:54 GMT @ T-00:15 – The Sound Suppression Water System has been activated to protect Atlantis and the launch pad from acoustical energy and rocket exhaust reflected from the flame trench and Mobile Launcher Platform during launch.

– 19:19:38 GMT: @ T-00:31 – Auto-sequence start. Atlantis’ on-board computers have primary control of all vehicle’s critical functions.

19:18:09 GMT: Crew members close and lock their visors.

19:15:09 GMT: Start auxiliary power units.

19:12:39 GMT: Retract orbiter access arm.

12:54 GMT: The shuttle tanking went into a stable replenish and the countdown entered a 2.5 hour long inbuilt hold at T-3 hours. Count to pick up at 15:24 GMT

– The liquid hydrogen tanking has reached 98% and will transition from fast-full to top-off at 2700 l per minute.

– Liquid oxygen tanking changes to fast-fill mode at almost 6,000 l per minute. Liquid hydrogen is also in fast-fill phase adding almost 32,000 liters every minute into the external tank (ET).

– Launch teams began liquid oxygen tanking in the slow-fill phase adding 1,200 liters every minute.

10:55 GMT: Fueling of the External Tank began with liquid hydrogen (at 20K) started in the slow-fill mode. Liquid oxygen (at 90.188 K) will follow at 11:25 GMT.
