February 8, 2010 09:22 by scibuff

Update 2: I replaced the SD photos with the respective HD versions.

Update 1: See the mission details and more photos in my STS-130 Space Shuttle Endeavour post.

The milestones of STS-130 Space Shuttle Endeavour launch (reverse order):

~ 04:23:52 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.

- 04:22:40 GMT @ T+08:33 – External Tank (ET) separation.

- 04:22:39 GMT @ T+08:32 – Zero Thrust.

- 04:22:30 GMT @ T+08:23 -  Main Engine Cut-off (MECO). Endeavour has reach the planned orbit and is schedule to dock with the International Space Station on Flight Day 3.

- 04:21:49 GMT @ T+07:42 -  Negative Istres.

- 04:21:28 GMT @ T+07:21 -  Negative Moron.

- 04:21:15 GMT @ T+07:08 - Single Engine Press. Endeavour can reach the planned orbit on a single SSME should two of the engines fail.

- 04:20:47 GMT @ T+06:40 – Nominal Shutdown, Go for the plus X, Go for the pitch maneuver. After the External Tank (ET) separation (SEP) the orbiter’s Reaction Control System (RCS) will execute a negative Z (in the direction up through the roof) translation maneuver to move the orbiter away from the ET. The “go for the pitch” refers to the ET Photo maneuver, which is a pitch around of the orbiter that allows the crew to take pictures of the tank out of the overhead windows.

- 04:20:21 GMT @ T+06:14 – Press to MECO and Single Engine Zaragoza 104 – Endeavour 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.

- 04:19:37 GMT @ T+05:30 – Single Engine OPS-3 – Endeavour 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.

- 04:19:18 GMT @ T+05:11 – Press to ATO select Zaragoza – Endeavour 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).

- 04:17:59 GMT @ T+03:52 – Negative Return – Endeavour has used too much fuel and is traveling too fast (7,795 km/h), too high (96 km) and is too far (200 km) to return to the Shuttle Landing Facility (SLF) at the Kennedy Space Center (KSC) for a potential Return To Launch Site (RTLS) abort.

- 04:17:01 GMT @ T+02:54 – 2 engine Istres. Endeavour can now reach the Transoceanic Abort Landing (TAL) site in Istres in the case of a single engine failure.

- 04:16:50 GMT @ T+02:43 – 2 engine Zaragoza. Endeavour can now reach the TAL site in Zaragoza in the case of a single engine failure.

- 04:16:45 GMT @ T+02:38 – 2 engine Moron. Endeavour can now reach the TAL site in Moron in the case of a single engine failure.

- 04:16:22 GMT @ T+02:15 – Orbital Maneuvering System (OMS) assist.

- 04:16:12 GMT @ T+02:05Solid Rocket Booster (SRB) separation. Endeavour is at the altitude of 47.18 km, 44.57 km down range from the KSC, traveling at 4 794.4 km/h (Mach 4).

Flying upside down and backwards more than 300 km above the Indian Ocean just west of Indonesia, the crew executed the deorbit burn lasting 2 minutes and 47 seconds with the Time of Ignition (TIG) at at 13:37:10 GMT, slowing the orbiter down by about 340 km/h. The orbiter encountered the upper layers of the Earth’s atmosphere at around 14:12 GMT, marking the beginning of the entry interface (EI). At the time of EI, the shuttle was flying at Mach 25 with its nose elevated 40 degrees at of about 120km over the south Pacific ocean.

During the STS-129 mission’s (ISS assembly flight ULF3) 3 extra-vehicular activities (EVA’s), Atlantis crew installed the S-band Antenna Sub-Assembly (SASA), the GATOR (Grappling Adaptor to On-Orbit Railing) bracket to the Columbus laboratory, High Pressure Gas Tank (HPGT) on the Quest airlock, the ExPRESS Logistics Carrier 2 (ELC-2), deployed the S3 outboard Payload Attachment System, relocated the Floating Potential Measurement Unit, removed a pair of micrometeoroid and orbital debris (MMOD) shields from outside the airlock and strapped them to the External Stowage Platform #2, and shut down and packed the failed Urine Processor Assembly/Distillation Assembly (UPA DA).

EVA 3 marked the 230th conducted by U.S. astronauts, the 136th in support of Space Station assembly and maintenance, totaling 849 hours, 18 minutes and the 108th spacewalk out of the space station, totaling 662 hours, 3 minutes.

Atlantis brought home Expedition 20 and 21 Flight engineer Nicole Stott (@Astro_Nicole) (item number 914), who has become last of the shuttle rotating expedition crew members (ShRECs). She spent 87 days aboard the International Space Station and 91 days in space, which was apparently close enough to earn her NASA’s “100 Days In Space” patch, designed by astronaut Andy Thomas in 2004.

Tuesday, at 1500 GMT, European Space Agency astronaut Frank De Winne handed over command of the station to NASA astronaut Jeff Williams (@Astro_Jeff) in the. De Winne and Expedition 21 Flight Engineers Roman Romanenko and Robert Thirsk are scheduled to leave the station for return to Earth in a Soyuz capsule on November 30.

The next scheduled space shuttle mission is the STS-130 (ISS assembly flight 20A), targeted to launch on February 4, 2010 at 10:52 GMT, will be the 161st American manned space flight, the 32nd shuttle mission to the ISS and the 24th flight of the space shuttle Endeavour. The primary payloads are the Tranquility module and the Cupola, a robotic control station with six windows around its sides and another in the center that provides a 360-degree view around the station.

Atlantis is on the way home

November 25, 2009 10:03 by scibuff

Today at 09:53 GMT the Space Shuttle Atlantis undocked from the Harmony Node of the International Space Station (ISS) after 6 days, 17 hours and 2 minutes. The undocking occurred just northeast of Indonesia, while both the station and the shuttle were in the dark of the Earth’s shadow (as it usually is the case for undocking).

Yesterday, the STS-129 and Expedition 21 crew members parted ways with a change of command and farewell ceremony, where Expedition 21 Commander Frank De Winne handed over the command of the International Space Station to NASA’s astronaut Jeff Williams (@Astro_Jeff). After the farewell ceremony, the crews closed the hatches that divide the two spacecraft at 18:12 GMT.

After 87 days spent in the complex, Expedition 20 and 21 Flight engineer Nicole Stott (@Astro_Nicole), officially, item number 914, became the last astronaut who used the Space Shuttle for a lift to or from the station (as a member of the station’s Expedition crew). If Atlantis lands as scheduled, she will have spent 91 days in space.

Space Shuttle Orbital Maneuvering System (OMS) is scheduled to execute the deorbit burn at 13:37 GMT on Friday, leading to landing at the Kennedy Space Center (KSC) Shuttle Landing Facility (SLF) runway 33 at 14:44 GMT.

Space Shuttle Atlantis is headed for the ISS after almost two years.

Launch of the Space Shuttle Atlantis

November 16, 2009 at 19:28:08 GMT, NASA successfully launched the Space Shuttle Atlantis on its 31st flight and the 31st shuttle mission to the International Space Station (ISS). Atlantis is scheduled to dock with the ISS on November 18, after a two-day chase in the Low Earth Orbit (LEO). After nearly two years, orbiter Atlantis is set to make a return to the ISS, following the extremely successful flagship mission (STS-125) to repair the Hubble Space Telescope in May 2009.

Six crew members of STS-129, commanded by NASA veteran Charles O. Hobaugh (STS-104, STS-118), will stay in space 10 days, 19 hours, 14 minutes and land at the Kennedy Space Center at 14:43 GMT on November 27. STS-129 Pilot, Barry E.Wilmore, will be responsible for orbiter systems operations and will fly the orbiter during undocking and the flyaround. Mission Specialists Mike Foreman (STS-123), Robert L.Satcher Jr., and Randy Bresnik will combine for a total of 31 hours and 45 minutes during 3 planed spacewalks (EVA) on flight days 4, 6, and 8. Mission Specialist Leland D. Melvin (STS-122) will operate the robotic arm during EVA-1 and EVA-3.
