"Awesome" Launch for Atlantis

"What a truly awesome day today," said NASA Associate Administrator for Space Operations Bill Gerstenmaier at the STS-135 postlaunch news conference. "I'm really talking about the teams and the people who supported the launch that just occurred. What you saw is the finest launch team and shuttle preparation teams in the world."

"It truly was an awesome, spectacular launch," added Kennedy Space Center Director Bob Cabana, who looked ahead to plans for future development beyond the shuttle program as space station operations continue.

"We're really looking forward to a great mission. This is a very critical mission for station resupply. We're going to do our best to try and stretch out an extra day," said Space Shuttle Program Launch Integration Manager and chairman of the pre-mission Mission Management Team Mike Moses. "I think the shuttle program is ending exactly as it should. We've built the International Space Station, we're stocking it up for the future, and ready to hand it off, and we finish really, really strong."

"On behalf of the launch team, and all the thousands of people here at KSC, we're just very, very proud that we finished strong from the launch perspective," added Shuttle Launch Director Mike Leinbach.

Atlantis and its four astronauts lifted off from Launch Pad 39A at NASA's Kennedy Space Center in Florida at 11:29 a.m. EDT. Atlantis will dock with the space station on Sunday.

Atlantis Hatch is Closed for Flight

With all four astronauts aboard space shuttle Atlantis, the Close Out Crew sealed the hatch for flight and is verifying the integrity of the seal before breaking down the White Room and departing the launch pad.

Weather still is 30 percent "go" and while weather remains dynamic, Launch Director Mike Leinbach told the launch team earlier, "We do have a shot at this today."

There are no major technical issues and launch remains on schedule for 11:26 a.m. EDT for the final flight of the Space Shuttle Program.

End of an Era: Weather Briefings and Communicating Uncertainty

By Carla Voorhees

Kathy Winters is an Air Force Civilian Meteorologist at the 45th Weather Squadron at Cape Canaveral Air Force Station. She is the Space Shuttle Launch Weather Officer providing weather support to the Space Shuttle Program at Kennedy Space Center (KSC) as the Launch Team prepares for the 8 July 2011 launch of Atlantis. You can find out more about the 45th Space Wing at their Facebook page.

We had two significant weather briefings Wednesday, 6 July: the 45th Space Wing Launch Readiness Review and the Shuttle Mission Management Team Launch minus 2-day meeting. Both meetings are essential to determine launch readiness, and weather is one piece of the large puzzle of things that must come together for launch. During these meetings, our squadron presents weather forecasts for the rotating service structure retract, tanking, solid rocket booster recovery, launch, plus 24- and 48- hour launch delay forecasts. Spaceflight Meteorology Group also presents the abort landing weather during the Shuttle Mission Management Team meeting. During the briefings, weather threats are highlighted so the Shuttle and Space Wing teams know what to expect. Sometimes NASA managers change the time of a pre-launch operation if the current schedule puts the launch countdown at risk for a weather delay, but the launch window itself is not modified since it is based upon the rendezvous with the International Space Station on-orbit.

After the Mission Management Team meeting, I attend a press conference with the Shuttle Launch Director, Mike Leinbach, and the Shuttle Launch Integration Manager, Mike Moses.  Our squadron Launch Weather Officers interact with them often since weather affects so many Shuttle operations. We provide a weather briefing to Mike Leinbach and his team every weekday morning to plan ground operations around the weather, if necessary. We increase the briefings to a few updates per day when a hurricane threatens the Florida East Coast. Mike Moses and Mike Leinbach have heard so many of my weather briefings that they can tell from the tone of my voice how certain or uncertain I am about a particular weather forecast. One NASA manager called this “Human Capital,” the rapport these managers build with their team which results in the synergy needed during a challenging situation, such as a Shuttle rollback decision.

Another way we describe the forecast confidence in a particular weather situation is through probability forecasts. For launch, we provide the “Probability of KSC Weather Prohibiting Launch,” as opposed to an absolute forecast. We also provide probabilities for constraint violations during ground operations.  In fact, many Shuttle constraints include probabilities, such as for Shuttle rollout, the constraint is “no more than a 10% chance of lightning within 20nm.” If you view our weekly planning forecast, you will see the probability of precipitation and lightning our customers use for planning purposes. These probability forecasts help launch teams make cost/risk decisions.

Speaking of probabilities, Wednesday, we increased our probability of KSC weather prohibiting launch. Weather does not look good for Friday here on the Florida Space Coast! Check out our latest launch forecast.  Hopefully we’ll be able to launch Friday—check out the photo that shows you the view of the Shuttle launch from our building!

Launch Weather Forecast Remains 30 Percent "Go" for Friday

Following a meeting of the Mission Management Team this morning, STS-135 countdown and weather updates were provided at prelaunch news conference. Panelists included Mike Moses, Mission Management Team chair and space shuttle launch integration manager, Mike Leinbach, shuttle launch director, and Kathy Winters, shuttle weather officer.

"We had a really smooth Mission Management Team meeting today," said Moses. "The vehicle is in fantastic shape." In regard to the launch-day weather forecast, he added, "Before we go load the propellants into the tank we'll take a look at the weather and make sure it's really a good day to try that, and so at that point we'll be making a decision"

"The countdown so far is going extremely well," reported Leinbach. "We're not tracking anything at all that would prevent an on-time liftoff Friday morning."

"We have a tropical wave that's out in the Caribbean," explained Winters. "That wave is actually going to come into Florida along with a lot of tropical moisture that's down to the south, and it's all going to roll into Florida in the next couple of days." Based on these conditions, Winters predicted an 80 percent chance of weather preventing tanking operations, with a 70 percent chance of it standing in the way of launch at 11:26 a.m. on Friday.

The countdown for this final space shuttle launch began yesterday at 1 p.m. This morning at the T-27 hour mark, the countdown entered a planned hold at 5 a.m. and resumed at 9 a.m.

The Atlantis astronauts awoke at 4:30 a.m. to continue their preparations for launch.

Countdown Continues Toward Friday's Launch

The countdown for the final space shuttle launch began yesterday at 1 p.m. EDT, starting at the T-43 hour mark. However, the weather forecast looks less than favorable for Friday's launch, with only a 30 percent chance of a "go" at the 11:26 a.m. liftoff time.

At the 10 a.m. precountdown status briefing yesterday, NASA Test Director Jeremy Graeber reported space shuttle Atlantis is ready for flight, and STS-135 payload manager Joe Delai said the payloads are ready to go as well. The only issue standing in the way of liftoff is the chance of showers and thunderstorms developing along the sea-breeze front reported by Kathy Winters, shuttle weather officer.

Today's prelaunch news conference will begin at 11:30 a.m. EDT live on NASA TV and online at www.nasa.gov/ntv. Participants will be Mike Moses, Mission Management Team chair and space shuttle launch integration manager, Mike Leinbach, shuttle launch director, and Kathy Winters, shuttle weather officer.

Managers Say Atlantis is "Go" for Launch

After the day-long Flight Readiness Review at NASA's Kennedy Space Center in Florida, senior NASA and contractor managers voted unanimously to set space shuttle Atlantis' STS-135 launch date as July 8 at 11:26 a.m. EDT.

NASA Television will air a news conference at 3:30 p.m. to discuss the meeting and preparations for Atlantis' mission to the International Space Station. Participants will include Bill Gerstenmaier, assistant administrator for space operations, Mike Moses, Space Shuttle Program launch integration manager and Mike Leinbach, shuttle launch director.

A Great Launch, A Challenging Mission Ahead

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.

Shuttle MMT Green Lights Continuing Endeavour Countdown

The shuttle Mission Management Team is giving space shuttle Endeavour’s launch team the green light to continue the countdown for Monday’s 8:56 a.m. EDT liftoff. The MMT met this afternoon at NASA’s Kennedy Space Center in Florida and reviewed how launch preparations for Endeavour’s STS-134 mission are progressing.

During a news conference on NASA Television following the MMT, Shuttle Launch Director Mike Leinbach said the countdown is going extremely well and the team is ready to go.

The forecast still calls for a 70 percent chance of acceptable weather at launch time.

On Kennedy’s Launch Pad 39A, the rotating service structure is scheduled to be moved away from Endeavour starting at noon on Sunday. Endeavour’s external fuel tank is scheduled to be filled beginning at 11:36 p.m. Live NASA TV fueling commentary will begin at 11:30 p.m.

Teams Not Working Any Launch Issues, Post-MMT News Conference at 4 p.m. Eastern

Launch teams at NASA’s Kennedy Space Center are working through the countdown milestones with no issues that would delay space shuttle Endeavour’s launch Monday, May 16 at 8:56 a.m. EDT to the International Space Station. The countdown entered an 8-hour built-in hold at 11 a.m. at T-19 hours and will pick up again at 7 p.m. Technicians at Launch Pad 39A have completed loading cryogenic reactants into Endeavour’s fuel cell storage tanks. Teams will remove the orbiter mid-body umbilical unit, which was used to load the propellants into the power reactant distribution system later this afternoon.

Current forecasts still call for a 70 percent chance of acceptable conditions at launch time.

The Mission Management Team will meet at 3 p.m. MMT chair and Space Shuttle Launch Integration Manager Mike Moses, Shuttle Launch Director Mike Leinbach and Shuttle Weather Officer Kathy Winters will hold a news conference at 4 p.m. live on NASA TV and www.nasa.gov/ntv.

NASA Sets May 16 For Final Space Shuttle Endeavour Launch

CAPE CANAVERAL -- NASA managers have set the liftoff of space shuttle Endeavour for 8:56 a.m. EDT on Monday, May 16. Launch attempts are available through May 26, except for May 21. The STS-134 mission to the International Space Station is the penultimate shuttle flight and the final one for Endeavour.

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. They also discussed the progress of repairs since Endeavour's launch postponement on April 29.

A short in the heater circuit associated with Endeavour's hydraulic system resulted in the launch postponement. Technicians determined the most likely failure was inside a switchbox in the shuttle's aft compartment and associated electrical wiring connecting the switchbox to the heaters. The heater circuits prevent freezing of the fuel lines providing hydraulic power to steer the vehicle during ascent and entry.

The faulty box was replaced May 4. Since Friday, Kennedy technicians installed and tested new wiring that bypasses the suspect electrical wiring and confirmed the heater system is working properly. They also are completing retests of other systems powered by the switchbox and are closing out Endeavour's aft compartment.

STS-134 Commander Mark Kelly and his five crewmates are set to arrive at Kennedy for prelaunch preparations on Thursday, May 12, at approximately 11 a.m. NASA Television will broadcast the crew's arrival live. For NASA TV streaming video, downlink and scheduling information, visit http://www.nasa.gov/ntv.

The crew will deliver the Alpha Magnetic Spectrometer-2 (AMS) and critical supplies to the space station, including two communications antennas, a high-pressure gas tank and additional parts for the Dextre robot. AMS is a particle physics detector designed to search for various types of unusual matter. The crew also will transfer Endeavour's orbiter boom sensor system to the station, where it could assist spacewalkers as an extension for the station's robotic arm.

NASA Managers Meet to Discuss Endeavour's Launch

NASA managers have retargeted space shuttle Endeavour's launch to no earlier than Monday, May 16. After a meeting on Friday, they also extended the length of Endeavour's STS-134 mission to the International Space Station from 14 to 16 days. If Endeavour launches on May 16, liftoff would be at 8:56 a.m. EDT.

At 3 p.m. today, NASA Space Shuttle Program Launch Integration Manager Mike Moses and Shuttle Launch Director Mike Leinbach will hold a news conference at Kennedy Space Center in Florida to discuss the progress of repairs since Endeavour's launch postponement on April 29. The news conference will air live on NASA Television and online at www.nasa.gov/ntv.

Over the weekend, Kennedy technicians installed and checked out new wiring that bypasses the suspect electrical wiring connecting the switchbox to the heaters. They also ran the heaters for up to 30 minutes to verify they are working properly and complete retesting of the other systems powered by the switchbox. Teams will begin closing out Endeavour's aft compartment and will begin launch countdown preps today.

Space Shuttle Endeavour to Launch No Earlier Than May 16

NASA managers have retargeted space shuttle Endeavour's launch to no earlier than Monday, May 16. After a meeting on Friday, they also extended the length of Endeavour's STS-134 mission to the International Space Station from 14 to 16 days. If Endeavour launches on May 16, liftoff would be at 8:56 a.m. EDT.

At 3 p.m. on Monday, May 9, NASA Space Shuttle Program Launch Integration Manager Mike Moses and Shuttle Launch Director Mike Leinbach will hold a news conference at Kennedy Space Center in Florida to discuss the progress of repairs since Endeavour's launch postponement on April 29. The news conference will air live on NASA Television and online at www.nasa.gov/ntv.

Kennedy technicians are continuing work to resolve an issue in a heater circuit associated with Endeavour's hydraulic system that resulted in the launch postponement. Technicians determined the failure was inside an aft load control assembly, which is a switchbox in the shuttle's aft compartment, and possibly its associated electrical wiring.

Although the root cause of the failure in the switchbox has not been found, technicians are replacing hardware that could have caused the problem. The faulty box was changed Wednesday, and a test of nine shuttle systems powered by the new box is under way.

This weekend, technicians will install and check out new wiring that bypasses the suspect electrical wiring connecting the switchbox to the heaters. They also will run the heaters for up to 30 minutes to verify they are working properly and complete retesting of the other systems powered by the switchbox.

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 APUs and heater circuits to be operational for launch. On Endeavour's first launch attempt, one of two heaters for APU-1's fuel line did not work. Engineers confirmed the circuit in the original switchbox that directed power to the heaters was shorted out.

Launch attempts are available through May 26. May 21 is the only day a launch is not an option because it would lead to a May 23 docking with the space station. May 23 is when three of the space station's Expedition 27 crew members undock and return home in their Soyuz spacecraft. Managers reviewed the STS-134 mission timeline and determined the Endeavour crew can accomplish all objectives even with the departure of the three station crew members.

Endeavour's "Rollout" Gets the Green Light

Space shuttle Endeavour's move from NASA Kennedy Space Center's Vehicle Assembly Building to Launch Pad 39A is on track for tonight starting at 8 p.m. EST.

The launch team met for a final assessment at 3:30 p.m. and concluded that weather had improved sufficiently to support the move, known as "rollout."

Shuttle Launch Director Mike Leinbach gave the team the "go" to begin final roll preps with call-to-stations for the team beginning at 4 p.m. In addition, no significant technical issues are being worked.

NASA Television (www.nasa.gov/ntv) will air live video of the beginning of rollout starting at 8 p.m.

Discovery Lands for Final Time at 11:57 a.m. EST

At 11:57 a.m. EST, space shuttle Discovery landed for the final time at NASA’s Kennedy Space Center after 202 orbits around Earth and a journey of 5,304,140 miles on STS-133.

Discovery’s main gear touched down at 11:57:17 a.m. followed by the nose gear at 11:57:28 and wheels stop at 11:58:14 a.m. At wheels stop, the mission elapsed time was 12 days, 19 hours, four minutes and 50 seconds.

A post-landing news conference with managers at Kennedy is expected no earlier than 2 p.m. on NASA TV and http://www.nasa.gov/ntv. The participants will be Bill Gerstenmaier, associate administrator for Space Operations, Mike Moses, space shuttle launch integration manager, and Mike Leinbach, space shuttle launch director.

STS-133 was the 39th and final flight for Discovery, which spent 365 days in space, orbited Earth 5,830 times and traveled 148,221,675 miles.
