Go for Launch aprovado.
Sequência da descolagem:
The roll and pitch program will begin 10 seconds after Atlantis lifts off. The space shuttle will go through the region of maximum dynamic pressure at 49 seconds into the flight, and the solid rocket booster separation will occur at 2:05 minutes after launch. The orbital maneuvering system engines will begin firing at T+2:15 for just under three minutes to provide additional thrust. The shuttle will roll back to a heads-up position at 5 minutes 47 seconds in flight. The main engine cutoff will occur at 8 minutes 30 seconds after launch. The external tank will be jettisoned twenty seconds later.
At that time, Atlantis will be in an elliptical orbit of 137 statute miles by 36 statute miles. Then 45 minutes after launch, there will be a 2-minute burn of the orbital maneuvering system to raise the perigee, creating a more circular orbit of 143 by 116 statute miles. Atlantis' orbit will then gradually be raised and further circularized to rendezvous with the International Space Station which is at an altitude of 218 miles.
The primary overseas landing site is Moron, Spain, with Istres, France serving as back-up site. The Zaragoza, Spain site is under a threat of thunderstorms. The primary abort-once-around location is the Shuttle Landing Facility at the Kennedy Space Center, with the back-up site being White Sands Space Harbor in New Mexico. The primary end-of-mission site is the Shuttle Landing Facility at the Kennedy Space Center, and the alternate landing site is the Dryden Flight Research Facility at Edwards Air Force Base in California.

Mais uma missão do Space Shuttle Atlantis.
Parte mais logo à tarde.
Links no primeiro post.
Neste momento estamos em T - 3 horas e aguardando a contagem.
Aqui fica o que vai acontecer até à partida:
T-3 hours and holding
This built-in hold typically lasts two hours.
This built-in hold typically lasts 10 minutes.
T-20 minutes and counting
This is the final built-in hold, and varies in length depending on the mission.
T-9 minutes and counting

Neste momento estamos em T - 3 horas e aguardando a contagem.
Aqui fica o que vai acontecer até à partida:
T-3 hours and holding
This built-in hold typically lasts two hours.
- Perform inertial measurement unit preflight calibration
- Align Merritt Island Launch Area (MILA) tracking antennas
- Final Inspection Team proceeds to the launch pad to conduct a detailed analysis of the vehicle as the team walks up and down the entire launch tower
- Closeout Crew proceeds to the launch pad to configure the crew module for countdown and launch and assist the astronauts with entry into the orbiter
- Crew departs for the launch pad and, upon arriving at the pad, begins entry into the orbiter via the White Room
- Complete close-out preparations in the launch pad's White Room
- Check cockpit switch configurations
- Astronauts perform air-to-ground voice checks with Launch Control (Kennedy Space Center) and Mission Control (Johnson Space Center)
- Close the orbiter's crew hatch and check for leaks
- Complete White Room close-out
- Close-out crew retreats to fallback area
This built-in hold typically lasts 10 minutes.
- Shuttle Test Director conducts final launch team briefings
- Complete inertial measurement unit preflight alignments
T-20 minutes and counting
- Transition the orbiter's onboard computers to launch configuration
- Start fuel cell thermal conditioning
- Close orbiter cabin vent valves
- Transition backup flight system to launch configuration
This is the final built-in hold, and varies in length depending on the mission.
- The Launch Director, Mission Management Team and Shuttle Test Director poll their teams for a go/no go for launch
T-9 minutes and counting
- Start automatic ground launch sequencer
- Retract orbiter access arm (T-7 minutes, 30 seconds)
- Start auxiliary power units (T-5 minutes, 0 seconds)
- Arm solid rocket booster range safety safe and arm devices (T-5 minutes, 0 seconds)
- Start orbiter aerosurface profile test, followed by main engine gimbal profile test (T-3 minutes, 55 seconds)
- Retract gaseous oxygen vent arm, or "beanie cap"
(T-2 minutes, 55 seconds) - Crew members close and lock their visors
(T-2 minutes, 0 seconds) - Orbiter transfers from ground to internal power
(T-50 seconds) - Ground launch sequencer is go for auto sequence start (T-31 seconds)
- Activate launch pad sound suppression system
(T-16 seconds) - Activate main engine hydrogen burnoff system

- Solid rocket booster ignition and liftoff!
Neste momento estão a instalar os astronautas nos seus lugares.
Aquilo ainda tem muito que se lhe diga para preparar tudo...
Estavas à espera que estivessem todos aos pulos [
][]Aquilo está a ser feito como deve ser, um astronauta de cada vez e cada um demora uns 10-20 minutos...

Bem, agora que faltam menos de 20 minutos a coisa começa a ficar interessante. Pelo que vou ouvindo (o meu pc parece uma torre de controlo, com o som das transmissões deles[]), está uma equipa (ice crew) a fazer um check visual a algum gelo que está acumulado algures.
Agora é aguardar pela mítica contagem dos 10-9-8-7...[
