Endeavour (STS-134 / ULF6) delivers EXPRESS Logistics Carrier-3 (ELC-3) and an Alpha Magnetic Spectrometer (AMS) to the International Space Station.

NASA Assigns Crew for STS-134 Shuttle Mission, Change to STS-132 :: August 11, 2009 :: WASHINGTON -- NASA has assigned the crew for space shuttle mission STS-134 to the International Space Station. The flight will deliver the Alpha Magnetic Spectrometer, or AMS, to the station. The AMS is a state-of-the-art cosmic ray particle physics detector designed to examine fundamental issues about matter and the origin and structure of the universe. Navy Capt. Mark Kelly (1996/16:STS-121/STS-124) will command the STS-134 mission, which is targeted to launch 26-Feb-2011 @ 4:04 p.m. EST. Retired Air Force Col. Gregory H. Johnson (1998/17:STS-123) will serve as the pilot. Mission Specialists are Air Force Col. Michael Fincke (1996/16:ISS-18 CDR), Greg Chamitoff (1998/17:ISS 17-18) and Andrew Feustel (2000/18:STS-125). European Space Agency astronaut and Italian Air Force Col. Roberto Vittori (ESA 1998:17/ISS Eneide) also will serve as a mission specialist. The flight will include three spacewalks and the installation of the AMS to the exterior of the space station using both the shuttle and station arms. The AMS will be attached to the right side of the station's truss, or backbone.

Last Two Shuttle Missions Planned Changes :: Mon, 26 Apr 2010 04:17:18 PM PDT :: NASA is planning to make some changes to the target launch dates for the last two scheduled space shuttle flights. Scientists with the Alpha Magnetic Spectrometer, or AMS, program recently decided to change out the current magnet in the particle physics experiment module that will be attached to the International Space Station to a longer lasting one. This will take advantage of NASA’s plan to extend station operations until at least 2020. Because of the magnet change, space shuttle Endeavour’s STS-134 mission, which will carry the AMS experiment to the station and was targeted to launch July 29, now is expected to launch no earlier than mid-November 2010. An exact target launch date still is TBD. AMS is designed to help study the formation of the universe and search for evidence of dark matter and antimatter by measuring cosmic rays. Space shuttle Discovery’s STS-133 mission currently remains targeted for its Sept. 16 launch date, but managers will continue to assess its readiness for flight and make changes as appropriate. [+]

NASA Updates Shuttle Target Launch Dates For Final Two Flights :: July 01, 2010 :: WASHINGTON -- NASA is targeting approximately 4:40 p.m. EDT on Nov. 1 for the launch of space shuttle Discovery's STS-133 mission and 4:04 p.m. EST on Feb. 26, 2011, for the liftoff of shuttle Endeavour's STS-134 flight from the Kennedy Space Center in Florida. The target dates were adjusted because critical payload hardware for STS-133 will not be ready in time to support the previously planned Sept. 16 launch. With STS-133 moving to November, STS-134 cannot fly as planned, so the next available launch window is in February 2011. NASA will schedule the official launch date for each mission following the agency's Flight Readiness Reviews, which typically occur about two weeks prior to launches. All target launch dates are subject to change.

NASA's First Twins to Fly in Space Together :: 08.26.10 :: Scott will launch to the International Space Station aboard a Russian Soyuz spacecraft [Soyuz TMA-01M | Expedition 25 | Expedition 26] from the Baikonur Cosmodrome in Kazakhstan on Oct. 7. (Oct. 8. local time). Mark will command the last scheduled space shuttle flight, STS-134, in February 2011. If the launch schedule holds, the pair will be working together in orbit for eight days before the shuttle undocks and returns to Earth.

International Partners Update Space Station Launch Manifest :: Oct. 1, 2010 :: WASHINGTON -- NASA, the European Space Agency (ESA) and the Russian Federal Space Agency (Roscosmos) agreed on Friday to update the International Space Station launch schedule. The target launch dates for the last planned space shuttle flight, STS-134 on Endeavour, will be Feb. 27, 2011, and the Automated Transfer Vehicle-2 (ATV-2) will be Feb. 15. Roscosmos will continue to look at Soyuz launch and landing options to provide manifest robustness. The agencies agreed to the changes during discussions at the International Astronautical Conference in Prague. Arianespace, whose Ariane 5 rocket will launch ATV-2 into orbit from French Guiana, has confirmed its commitment to launch on Feb. 15. [+]

NASA Updates Shuttle Target Launch Dates For Two Flights :: Jan. 13, 2011 :: WASHINGTON -- NASA is targeting 4:50 p.m. EST on Thursday, Feb. 24, for the launch of space shuttle Discovery's STS-133 mission to the International Space Station. The liftoff of shuttle Endeavour's STS-134 flight is planned for 7:48 p.m. EDT on April 19, from NASA's Kennedy Space Center in Florida. The target dates were selected Thursday during the Space Shuttle Program's weekly Program Requirements Control Board meeting.

NASA Retargets Space Shuttle Endeavour's Launch For April 29 :: April 04, 2011 :: WASHINGTON -- Following discussions among the International Space Station partners on Sunday, NASA has targeted the launch of space shuttle Endeavour's STS-134 mission for 3:47 p.m. EDT on Friday, April 29. The delay removes a scheduling conflict with a Russian Progress supply vehicle scheduled to launch April 27 and arrive at the station April 29. NASA managers will hold a Flight Readiness Review on Tuesday, April 19, to assess the team's readiness to support launch. An official launch date will be selected at the conclusion of the meeting. The Progress 42 spacecraft will be delivering supplies to the station. Three more members of the Expedition 27 crew are scheduled to launch at 6:18 pm EDT on Monday, April 4, from the Baikonur Cosmodrome in Kazakhstan. Their arrival will return the station crew's size to six members. Russian cosmonauts Andrey Borisenko and Alexander Samokutyaev and NASA astronaut Ron Garan are scheduled to arrive at the station at 7:18 p.m., Wednesday, April 6, to join cosmonaut Expedition 27 Commander Dmitry Kondratyev, European Space Agency astronaut Paolo Nespoli and NASA astronaut Cady Coleman, who have been aboard the station since mid-December.

Additional Day Added to STS-134 Mission :: Wed, 13 Apr 2011 08:50:49 AM PDT :: Shuttle managers have officially added an additional day to space shuttle Endeavour's STS-134 mission making it a 15-day flight. With launch targeted on April 29, landing at Kennedy's Space Shuttle Landing Facility would be on Saturday, May 14 at 9:51 a.m. EDT. The extra day will be put in after Flight Day 9 as a new Flight Day 10 to accommodate work on the U.S. carbon dioxide removal system and other International Space Station tasks. The Flight Readiness Review for Endeavour's flight to the space station will be held on Tuesday, April 19. NASA managers will announce the official launch date during a briefing at the conclusion of the meeting.

Flight Planning Returns to a 14-Day Mission :: Fri, 15 Apr 2011 09:42:29 AM PDT :: Space shuttle managers have decided to keep shuttle Endeavour’s STS-134 mission as a 14-day flight and possibly extend the mission as many as two days while Endeavour is in space. The program had extended the mission one day on Wednesday, but managers determined late yesterday that they will keep it at a 14-day flight for the time being. Once Endeavour is in space, managers will evaluate the shuttle’s performance and other mission objectives and then decide whether to add another day or two to the flight to support operations aboard the International Space Station. The first landing opportunity at Kennedy is Friday, May 13 at 9:28 a.m. EDT. All schedules will be discussed at Tuesday’s Flight Readiness Review meeting at Kennedy. Launch remains targeted for April 29 at 3:47 p.m.

Endeavour Launch Scrubbed :: Fri, 29 Apr 2011 09:18:33 AM PDT :: Shuttle Launch Director Mike Leinbach has scrubbed today's STS-134 launch attempt because of an issue associated with Auxiliary Power Unit 1 heaters. There will be at least a 72-hour scrub turnaround while engineers assess the issue. NASA Television will air a news conference 4 p.m. EDT.

Engineers and Managers to Assess APU Issue :: Fri, 29 Apr 2011 10:14:11 AM PDT :: Shuttle launch director Mike Leinbach stated that Endeavour's launch will be no earlier than Monday at 2:33 p.m. EDT. Engineers need that time to troubleshoot an issue that resulted in today’s launch scrub. During today’s countdown, engineers detected a failure in one of two heater circuits associated with Auxiliary Power Unit (APU) 1. Heaters are required to keep the APUs’ hydrazine from freezing on orbit. Attempts to activate the heater were not successful and engineers now believe the problem might be associated with a Load Control Assembly, which is a switchbox, located in the aft end of Endeavour, or an electrical short in the wires leading into or out of the switchbox. Endeavour’s external tank will be drained, technicians will enter Endeavour’s aft compartment overnight and by tomorrow afternoon, will put in a platform to gain access to the avionics bay where the Load Control Assembly is located. Once there, they will assess whether they need to remove and replace the switchbox, or fix an electrical wiring short. Because of this, Leinbach said there will be a minimum 72-hour scrub turnaround. Engineers and managers will meet this afternoon to further refine their troubleshooting plan. NASA has scheduled a news conference at no earlier than 4:30 p.m. to discuss today’s scrub and the plan and will be aired on NASA TV (www.nasa.gov/ntv).

NASA Resets Shuttle Endeavour's Launch for No Earlier Than May 2 :: April 29, 2011 :: WASHINGTON -- NASA managers met Friday to discuss the status of space shuttle Endeavour's launch to the International Space Station. The launch was postponed because of a heater issue associated with the shuttle's hydraulic power system. The next launch attempt will be no earlier than May 2. The shuttle has three Auxiliary Power Units (APUs) that provide hydraulic power to steer the vehicle during ascent and entry. NASA launch commit criteria and flight rules require all three APUs to be fully operational for launch. Endeavour's external fuel tank was drained of more than 500,000 gallons of liquid hydrogen and oxygen so engineers can access the area Saturday and evaluate the issue with APU 1.

Endeavour APU Issue Testing Under Way :: Sat, 30 Apr 2011 02:29:01 PM PDT :: Teams at NASA Kennedy Space Center's Launch Pad 39A are testing various systems in space shuttle Endeavour to determine the cause of the heater issue associated with auxiliary power unit-1 (APU-1). Technicians gained access to the spacecraft earlier this afternoon. They were able to confirm the cockpit control fuse panel is working. Teams began testing thermostats associated with the heater connected to the fuel line for the APU. Initial reports indicate the thermostat side that failed during Friday's launch countdown still is not working, as expected. Teams will continue additional testing to help determine whether the thermostat is receiving a current or whether the issue is being caused by another part of the system. Managers are not expected to decide until Sunday morning, at the earliest, whether a launch attempt on Monday is possible. Flight Dynamics at NASA's Johnson Space Center in Houston has refined the target launch time for Monday to 2:34:00 p.m. EDT.

@NASA :: 3:14PM Apr 30th :: If technicians find and fix the heater issue in time to launch Endeavour Monday, the launch time has changed to 2:34 p.m. EDT.

Shuttle Endeavour Launch No Earlier Than May 8 :: May 1, 2011 :: CAPE CANAVERAL -- NASA managers have determined space shuttle Endeavour will not launch before Sunday, May 8, but will not officially set a new launch date until early this week. After Friday’s launch scrub, Kennedy Space Center technicians searched for the cause of a failure in a heater circuit associated with Endeavour’s hydraulic power system. The failure was found to be in a power circuit in a switchbox in the shuttle’s aft compartment. Managers and engineers are developing a schedule to remove and replace the switchbox and retest the new unit. That work will delay Endeavour’s launch until at least May 8. The shuttle has three Auxiliary Power Units (APUs) that provide hydraulic power to steer the vehicle during ascent and entry. The hydrazine fuel lines on each APU have two heater circuits that prevent the fuel from freezing while the shuttle is in space. NASA launch commit criteria and flight rules require all three APUs and heater circuits to be operational for liftoff. Endeavour’s six astronauts have returned to NASA’s Johnson Space Center in Houston for several days of additional training.

Two Events Commemorate 50th Anniversary of U.S. Human Spaceflight :: May 2, 2011 :: WASHINGTON -- NASA Administrator Charles Bolden will commemorate the 50th anniversary of the first U.S. manned spaceflight during two events this week around the agency's Kennedy Space Center in Florida. NASA Television will carry both events live. On Wednesday, May 4, at 2 p.m. EDT, the U.S. Postal Service will unveil two new stamps at the Rocket Garden of the Kennedy Space Center Visitor Complex, located on State Road 405… One stamp commemorates NASA's Project Mercury and Alan Shepard's historic launch on May 5, 1961 aboard the spacecraft Freedom 7. The second stamp honors NASA's MESSENGER, which reached Mercury in March to become the first spacecraft to orbit the planet. The two missions frame a remarkable 50-year period in which America advanced space exploration through more than 1,500 manned and unmanned flights. » USPS: Astronaut Alan Shepard Immortalized on Forever Stamp

Endeavour's Launch Will Occur No Earlier Than May 10 :: Mon, 02 May 2011 02:32:28 PM PDT :: NASA space shuttle and International Space Station managers met Monday and determined that Tuesday, May 10 is the earliest Endeavour could be launched on the STS-134 mission. That date is success oriented based on preliminary schedules to replace a faulty Load Control Assembly (LCA) box in the orbiter's aft compartment. Plans are for managers to reconvene Friday to determine a more definite launch date after the box is removed and replaced and the retest of systems has been completed. Space Shuttle Program managers adjusted the date after further evaluating the schedules to change out the box and retest the nine shuttle systems associated with the controller. That work would be followed by the standard closeout of the aft compartment before proceeding into the launch countdown. Sunday night and Monday, technicians at NASA's Kennedy Space Center’s Launch Pad 39A conducted additional testing of systems associated with LCA-2, including testing the box itself, which is expected to be removed late Monday or early Tuesday and replaced with an existing spare. Managers will continue to evaluate the repair process and make any additional adjustments before scheduling Endeavour’s next launch attempt for its STS-134 mission to the International Space Station. The STS-134 crew is back in Houston and remains in quarantine throughout as it slowly adjusts its wake and sleep schedule to match the new launch time. While at NASA's Johnson Space Center, the crew will conduct a launch and landing simulation with its ascent and entry flight control team based in Mission Control, before returning to Florida for the launch countdown.

Endeavour's Launch Set for May 16 :: Mon, 09 May 2011 12:40:11 PM PDT :: NASA managers have set the liftoff of space shuttle Endeavour for 8:56 a.m. EDT on Monday, May 16. Space Shuttle Program Launch Integration Manager Mike Moses and Shuttle Launch Director Mike Leinbach announced the date at a news briefing Monday from NASA's Kennedy Space Center in Florida.

Liftoff of Space Shuttle Endeavour! :: Mon, 16 May 2011 05:56:43 AM PDT :: Space shuttle Endeavour and its crew of six astronauts are headed for space, ready to begin their 16-day mission to the International Space Station. The climb to orbit takes about 8 1/2 minutes. Following a relatively smooth countdown, the weather cooperated leading to an on-time liftoff from Launch Pad 39A at NASA's Kennedy Space Center in Florida at 8:56 a.m. EDT. NASA TV will air a post-launch news conference at no earlier than 10 a.m. and on the Web at www.nasa.gov/ntv.

Crew Begins First Full Day on Orbit :: Mon, 16 May 2011 09:14:01 PM PDT :: The STS-134 crew of space shuttle Endeavour kicked off its first full day on orbit with a wakeup call at 11:56 p.m. EDT Monday. The wakeup music was “Beautiful Day” by U2, played for Commander Mark Kelly.

A Great Launch, A Challenging Mission Ahead :: Mon, 16 May 2011 08:35:13 AM PDT :: Space shuttle Endeavour is officially on its way to the International Space Station on its STS-134 mission and final flight. Endeavour lifted off from NASA's Kennedy Space Center on time at 8:56 a.m. EDT, soaring through a few clouds, after a relatively smooth countdown. "I can't thank the teams that got this vehicle ready to fly and for all the work they've done," said Associate Administrator for Space Operations Bill Gerstenmaier referring to the Auxiliary Power Unit (APU) heater issues and said, "The teams worked really hard to get through that, get it behind and to understand what the problem was -- and it was no problem to us at all during the count." "The teams stayed focused, and made this launch a success," Gerstenmaier added. "The mission in front of us is no easy mission, the EVAs (extra vehicular activities) are very demanding -- but it'll be exciting to see the AMS (Alpha Magnetic Spectrometer) get installed on the station and get some real research data for the ISS." "We showed our determination to succeed on a very complex mission," said Michel Tognini, head of the European Astronaut Center and former ESA astronaut, "and this is the model of human exploration for the future." Mike Moses apologized (in jest) about the view not being the best and the longest because of the cloud cover." But the data that we were looking at in the launch center was absolutely perfect," said Moses. "We had the clouds where we needed them, so we went." There were a few minor problems, but they were managed and worked immediately, including the minor tile repair, reported Moses. After every launch an award is given to one of the teams, according to Shuttle Launch Director Mike Leinbach, and today's honor was given to the combined APU repair/test team. "It was an outstanding countdown, lots of pats on the back in the lobby of the LCC (launch control center) afterwards when we were eating our beans and corn bread (a traditional post-launch snack)," said Leinbach. "Endeavour's on orbit safely and it's going to perform a great mission and we'll see her back here on June 1." "It's a great day here at Kennedy Space Center and for the Shuttle Program," added Leinbach.
