STS-126 Landing Blog

Sun, 30 Nov 2008 19:41:02 GMT
Endeavour is scheduled to land today at 4:25 p.m. at NASA’s Dryden Flight Research Center in California’s Mojave Desert.

The NASA center is adjacent to Edwards Air Force Base. Poor weather forced mission controllers to wave off a pair of landing opportunities at NASA’s Kennedy Space Center in Florida.

Astronauts Leave Endeavour
Sun, 30 Nov 2008 05:22:14 PM EST
The seven astronauts who returned to Earth aboard Endeavour are moving into the Crew Transport Vehicle which is parked at Endeavour's hatch. The CTV, as it is called, is similar to the people-movers used at some airports. It is just one vehicle parked by the shuttle now as technicians continue an extensive list of duties to ready Endeavour for its eventual move off the runway.

Endeavour's Week Ahead
Sun, 30 Nov 2008 05:12:13 PM EST
For space shuttle Endeavour, landing at California means several days of servicing and preparation so it can be loaded on the top of a modified 747 aircraft and flown back to NASA's Kennedy Space Center in Florida. Endeavour, which landed today at NASA's Dryden Flight Research Center in California because of poor weather in Florida, will be fitted with an aerodynamic cone over its main engines and orbital maneuvering system engines. Dryden and Kennedy are both equipped with special equipment to lift the shuttle and connect it to the 747.

Astronauts Cleared to Remove Entry Suits
Sun, 30 Nov 2008 04:55:04 PM EST
The seven astronauts aboard space shuttle Endeavour will begin removing their orange launch-and-entry suits as post-landing work continues on schedule at NASA's Dryden Flight Research Center in California. Today's landing marked the 19th time a shuttle landing has been diverted to Dryden because of weather. It was the seventh time Endeavour has landed at the West Coast center, and, overall, the 52nd time a shuttle has landed there. One shuttle mission, STS-3, landed at White Sands Space Harbor in New Mexico. Seventy-one have concluded at Kennedy, the launch site for the shuttle fleet.

Shuttle Techs Move In
Sun, 30 Nov 2008 04:45:34 PM EST
Just as they would for a Florida landing, a team of technicians in California is evaluating the outside of Endeavour before allowing large equipment trucks and more technicians to begin intensive post-landing work on the shuttle. The evaluation team uses special equipment to look for signs of abnormal chemical buildup around Endeavour. The team has the same gear at NASA's Dryden Flight Research Center that they use for landings at NASA's Kennedy Space Center in Florida. There are about 80 employees stationed at the California center for landing operations. Another 200 will fly to Dryden from Kennedy on Monday.

Stat Check for STS-126
Sun, 30 Nov 2008 04:36:51 PM EST
Endeavour's mission to the International Space Station ended when the shuttle's motion stopped at 4:26:03 p.m. The mission lasted 15 days, 20 hours, 30 minutes and 34 seconds. The shuttle traveled 6,615,109 miles during its 250 orbits of Earth. It was the 27th shuttle mission to the space station, and the 124th shuttle mission overall.

Wheelstop. STS-126 is over
Sun, 30 Nov 2008 04:27:41 PM EST
After 250 orbits of Earth, STS-126 has concluded safely with space shuttle Endeavour executing a perfect entry and landing at NASA’s Dryden Flight Research Center. "That was a great way to end a fantastic flight," Capcom Alan Poindexter radioed the crew from Mission Control. The astronauts aboard the shuttle have about an hour of duties in front of them to “safe” the vehicle so technicians can get it ready to move into its protective orbiter processing facility.

Touchdown!
Sun, 30 Nov 2008 04:25:22 PM EST
Endeavour is home!

Gear Down!
Sun, 30 Nov 2008 04:25:07 PM EST
Endeavour’s main gear and nose wheels are down and locked for landing.

Endeavour on Final Approach
Sun, 30 Nov 2008 04:24:17 PM EST
Space shuttle Endeavour has lined up with the runway and will drop its landing gear moments before landing.

Sonic Booms Announce Endeavour's Arrival
Sun, 30 Nov 2008 04:21:18 PM EST
A pair of sonic booms -- one from the nose and one from Endeavour’s tail -- have heralded the shuttle’s return to the skies over Southern California. Endeavour will make a long, sweeping turn to line up with runway 4 at NASA’s Dryden Flight Research Center.

Cameras Pick Up landing Shuttle
Sun, 30 Nov 2008 04:18:09 PM EST
Long-range cameras are focused on Endeavour now as it descends toward Dryden Flight Research Center in California. All the shuttle systems are operating well and the shuttle is set to land at 4:25 p.m

Landing 10 Minutes Away
Sun, 30 Nov 2008 04:14:21 PM EST
Space shuttle Endeavour is nearing the California coast on its way to Dryden Flight Research Center for a 4:25 p.m. landing.

Gravity Sensations Return to Crew
Sun, 30 Nov 2008 04:10:59 PM EST
Astronaut Greg Chamitoff has not felt gravity for about six months until now. Chamitoff is on the lower deck of Endeavour’s crew compartment and laying in a chair on his back to help his transition. The crew reports all systems are operating as they should.

Endeavour Doing Well During Entry
Sun, 30 Nov 2008 04:04:13 PM EST
Flight controllers at NASA’s Johnson Space Center in Houston report Endeavour is on course during its entry into Earth’s atmosphere. The spacecraft is protected by the heat shield from the hot plasma field surrounding the shuttle during the descent. It is halfway through the peak temperatures it will encounter during entry. Endeavour's speed is about 15,700 mph, or 23 times the speed of sound. It has 2,300 miles to go to reach Dryden.

Entry Interface
Sun, 30 Nov 2008 03:58:52 PM EST
Endeavour is encountering the first layers of thickening atmosphere as it descends toward Earth. The friction of the atmosphere will slow the spacecraft throughout entry, with the heat shield handling the work of protecting Endeavour. The shuttle orbits at about 17,500 mph, but will slow quickly as it moves into the thickening air. Endeavour is 59 miles above the pacific Ocean southwest of California and on target for a 4:25 p.m. landing.

The Landing Ahead
Sun, 30 Nov 2008 03:48:06 PM EST
Endeavour will encounter the first traces of Earth's thickening atmosphere at 3:52 p.m., with the highest temperatures taking place for about 10 minutes beginning at about 4 p.m.
The shuttle will slow to about 2.5 times the speed of sound at 3:17 p.m. when it is about 80,000 feet above the planet -- more than twice as high as an airliner typically flies. At 3:19,
Endeavour will slow to Mach 1. Commander Chris Ferguson will guide Endeavour through a series of roll maneuvers which help slow the spacecraft throughout the descent. The process culminates with Endeavour taking a wide turn over Dryden Flight Research Center in California to line up precisely with the runway for a landing at 4:25 p.m.

Where They are Sitting
Sun, 30 Nov 2008 03:28:11 PM EST
Commander Chris Ferguson, Pilot Eric Boe and mission specialists Steve Bowen and Shane Kimbrough are sitting on the flight deck for the entry phase of STS-126. Heidemarie Stefanyshyn-Piper is on the lower level closest to the hatch and Donald Pettit is to her right. Greg Chamitoff, who has spent the past six months living on the International Space Station, is on the far right side of the middeck. Chamitoff, like all returning station crew members, is sitting on the shuttle’s middeck, or lower level. He is strapped into a seat with his feet pointed toward the ceiling. That position makes the transition back to gravity easier on the body. Sandra Magnus, who flew into space with the STS-126 crew, took Chamitoff’s place on the station. Everything is going well and on track for a 4:25 p.m. landing at Dryden Flight Research Center.

Burn Executed, Endeavour Adjusts for Entry
Sun, 30 Nov 2008 03:22:56 PM EST
The orbital maneuvering system engines in the rear of Endeavour performed flawlessly for the prescribed 2-minute, 54-second burn, according to Mission Control. Now, Commander Chris Ferguson and Pilot Eric Boe are flipping the shuttle so its armored belly and nose are facing Earth at an angle. The spacecraft will encounter the first thin layers of the atmosphere in about 35 minutes.

Deorbit burn begins!
Sun, 30 Nov 2008 03:20:03 PM EST
Endeavour’s two orbital maneuvering system engines ignited on time and will fire for less than three minutes to slow the spacecraft down so it can begin its entry into Earth’s atmosphere. Everything remains on track for a 4:25 p.m. landing at Dryden Flight Research Center in California. Endeavour will be slowed by about 200 mph, which is just enough to let gravity take over and pull it into the Earth's atmosphere for the descent to California.

Shuttle to Soar over Southern California
Sun, 30 Nov 2008 03:08:03 PM EST
Endeavour will glide in over Greater Los Angeles, Calif., from the west and then make a sweeping turn to set up a final approach from the southwest to a temporary runway at Dryden. The runway is a 12,000-foot-long, 200-foot-wide stretch of concrete and asphalt that runs parallel to the permanent runway at Dryden. The permanent runway is closed for upgrades and maintenance, but will be available for future shuttle landings. The shuttle crew will fire Endeavour's braking rockets at 3:19 p.m. for a landing at Dryden at 4:25 p.m.

Endeavour Go for Deorbit Burn
Sun, 30 Nov 2008 02:58:13 PM EST
Endeavour has been cleared to land at Dryden during the first attempt of the day. “Endeavour, Houston. You are go for deorbit burn,” Capcom Alan Poindexter radioed to STS-126 Commander Chris Ferguson. Ferguson will ignite the twin orbital maneuvering system thrusters at 3:19 p.m. to begin the shuttle’s return to Earth. Landing remains scheduled for 4:25 p.m.

Crew sees Florida Weather from Space
Sun, 30 Nov 2008 02:51:49 PM EST
"I think you made a good call," STS-126 Commander Chris Ferguson told Mission Control at Johnson Space Center in Houston as Endeavour's crew observed Florida from space. High crosswinds and thunderstorms were developing in Florida as a weather front approached the prime landing location at NASA’s Kennedy Space Center, so mission controllers opted to send Endeavour to the sunny skies of California, instead.

Landing Weather a California Dream
Sun, 30 Nov 2008 02:41:02 PM EST
Astronaut Pam Melroy is flying a Shuttle Training Aircraft through clear blue skies above Edwards Air Force Base in California so she can advise STS-126 Commander Chris Ferguson what to expect as he guides the shuttle through its final approach and landing later today. The temperature at landing is expected to be about 66 degrees F. In space, Endeavour closed its cargo bay doors earlier and Ferguson is loading the appropriate software into the shuttle's computers.

Endeavour Scheduled for California Landing Today
Sun, 30 Nov 2008 02:30:18 PM EST
Good afternoon and welcome to NASA’s Landing Blog! The stage is set for the triumphant return of space shuttle Endeavour after the successful equipment, re-supply and maintenance mission to the International Space Station.
Endeavour is scheduled to land today at 4:25 p.m. at NASA’s Dryden Flight Research Center in California’s Mojave Desert. The NASA center is adjacent to Edwards Air Force Base. Poor weather forced mission controllers to wave off a pair of landing opportunities at NASA’s Kennedy Space Center in Florida

Good night from Firing Room 3 at Kennedy Space Center!

8:04 p.m. - External Tank is jettisoned and Endeavour is safely in orbit! All systems are running well.

8:03 p.m. - MECO! Main Engine Cutoff. Endeavour will jettison the external tank momentarily.

7:59 p.m. - Four minutes into flight, Endeavour is moving faster than 6,000 mph. All engines working well.

7:58 p.m. – Endeavour jettisoned the two solid rocket boosters. Its three liquid-fueled main engines are working properly. The shuttle continues to pick up speed.

7:56 p.m. – Endeavour is soaring through the sound barrier as it quickly picks up speed. It is riding about 7 million pounds of thrust from the combined power of its twin solid rocket boosters and three main engines.

7:55 p.m. - “Preparing our home in space for a larger international family,” said Launch Commentator Candrea Thomas.

7:55 p.m. – LIFTOFF of space shuttle Endeavour!

77:54 p.m. – T- one minute and counting . . . All systems go for launch!

7:53 p.m. – T-2 minutes and counting . . . The oxygen vent arm is retracting out of Endeavour’s way.

7:52 p.m. – T-3 minutes and counting . . . The three main engines are moving through a series of tests to make sure they are ready for launch.

7:50 p.m. – T-5 minutes and counting . . . The Auxiliary Power Unit aboard Endeavour is powering up. Commander Chris Ferguson said his crew will "Take space station construction to the next level" with STS-126.

7:48 p.m. – T-7 minutes and counting . . . The Orbiter Access Arm is retracting away from Endeavour’s hatch. It can be swung back into place in case of an emergency. "Good luck, Godspeed and have happy Thanksgiving in orbit," Launch Director Mike Leinbach told the astronauts.

7:46 p.m. - T-9 minutes and counting . . . Launch controllers have cleared the door issue, saying it does not pose a hazard to Endeavour as it climbs away from the launch pad. All launch teams are go for launch.

7:40 p.m. - Launch controllers are discussing a potential issue with a door in the White Room. There is concern whether the door has been pinned back. The door in question is not on Endeavour.

7:15 p.m. – For those just joining NASA’s Launch Blog today, Endeavour is on schedule to liftoff at 7:55 p.m.

STS-126 is known as a utilization and logistics flight to the International Space Station. Endeavour is carrying a cargo module called Leonardo that has been loaded with about 14,500 pounds of equipment and supplies. The gear includes a water recycling system, new crew quarters, an exercise device and a space kitchen. Once installed and operational, the equipment will support a station resident crew of six instead of the current three.

7:05 p.m. – A beautiful orange full moon has emerged just over the horizon at Kennedy to provide a fitting backdrop for the launch of Endeavour. Many of the experiments taking place on the International Space Station are focused on aspects of returning astronauts to the moon. For example, the water recycling system the astronauts will install in the space station will test processes that can be improved for moon missions in the future.

7:01 p.m. – T-9 minutes and holding . . . The countdown for STS-126 has entered its last built-in hold. The countdown will resume at about 7:46 p.m. aiming for a 7:55 p.m. launch.

6:55 p.m. - One hour before launch. There are no technical issues and weather conditions are expected to remain favorable. The Closeout Crew has left the launch pad.

6:50 p.m. – The countdown has resumed and is now T-19 minutes and counting. The last planned hold will take place at T-9 minutes. It will last 45 minutes and give flight controllers an opportunity to refine the launch time to put Endeavour on the best track to catch the International Space Station.

6:45 p.m. - As Endeavour leaves the launch pad, it will fly generally northeast, roughly paralleling the East Coast of the United States. Because the liftoff is taking place at night, people along the coast could have a better chance of seeing the shuttle streak overhead, depending on local conditions.

6:40 p.m. – At T-20 minutes, the countdown has entered a planned hold. The pause will last 10 minutes. Weather concerns continue to fade as the weather forecast has increased to an 80 percent chance of acceptable conditions at launch time. There are no technical issues and everything remains on pace to launch Endeavour tonight on a mission to the International Space Station.

6:35 p.m. – The Closeout Crew has put the final seals on the hatch and is packing up the White Room before leaving the launch pad.

6:10 p.m. - At T-50 minutes and counting, launch controllers report working through a technical issue with a computer processor that sends data from a high-altitude weather balloon. The problem did not pose a threat to launch. NASA uses large weather balloons to record conditions in the upper atmosphere leading up to launch. The countdown is proceeding on schedule.

6 p.m. - Endeavour's hatch has been closed and latched shut. The Closeout Crew will leave the launch pad shortly. The hatch is built to open if there is an emergency that requires the astronauts to evacuate the shuttle.

5:55 p.m. - Two hours to launch. Shuttle Endeavour has shown no technical issues during the countdown and the weather appears to be cooperating, as well. The sun has set at Kennedy and Endeavour is illuminated on the launch pad. The Closeout Crew is preparing to close and latch Endeavour's hatch for flight.

5:40 p.m. - Working out of two firing rooms, the launch team performs numerous checks and tests leading up to launch. One firing room houses the launch director, NASA test directors -- known as NTDs – and system engineers who monitor individual shuttle systems throughout the countdown. If they notice an issue, they call on managers and engineers in a second firing room who will track down the problem in detail and offer solutions. The process allows the engineer in the first firing room to keep up with fast-changing events while an issue is given proper attention.

A third is used to oversee the processing of shuttles for future missions. The fourth firing room has been completely rebuilt to support NASA’s new rocket, the Ares I. That firing room, named for the first shuttle crew of John Young and Robert Crippen, will guide the first test flight of the Ares I program next year.

5:25 p.m. - Astronaut Steve Bowen has taken his seat on the flight deck.

5:14 p.m. - The astronauts are conducting radio checks with launch controllers at Kennedy and mission controllers at NASA's Johnson Space Center in Houston. They will test their microphones individually before testing them all as a group.

5:11 p.m. - Steve Bowen will be the last crew member inside the shuttle. Bowen is the first submariner to fly for NASA. As the flight engineer, he will aid Commander Chris Ferguson during ascent. Bowen will call out launch milestones and perform other duties so Ferguson can keep his attention focused on the launch.

5 p.m. - Shane Kimbrough has donned a cloth, black headset that the astronauts wear under their helmets. He will enter Endeavour momentarily. Kimbrough began his NASA career flying in the Shuttle Training Aircraft as a flight engineer so commanders and pilots could simulate landing a shuttle returning from space.

4:55 p.m. - It's now Donald Pettit's turn to take a spot inside the shuttle. Because he sits on the flight deck, which is the upper level of the crew compartment, he will help Pilot Eric Boe keep track of events during the flight into orbit by reading off milestones during ascent and taking care of other duties.

4:50 p.m. - Heidemarie Stefanyshyn-Piper is preparing for her move into the shuttle. She is an accomplished Navy diver who found a natural career as a spacewalker. When training for a spacewalk, astronauts spend many hours underwater at the Neutral Buoyancy Laboratory at NASA's Johnson Space Center in Houston.

4:45 p.m. - Pilot Eric Boe is taking his seat in Endeavour's cockpit. Toward the end of the mission, Boe will fly Endeavour around the International Space Station as astronauts survey the orbiting laboratory.

4:35 p.m. - Sandra Magnus is the next into Endeavour. As an International Space Station crew member, she is also trained to fly aboard a Russian Soyuz spacecraft. STS-126 is her second flight. She served as a mission specialist during the STS-112 mission in 2002.

4:32 p.m. - Commander Chris Ferguson is the first to climb inside Endeavour. Smiling, he waved to his family before boarding the spacecraft. He will literally climb into his seat because he will be laying on his back for launch. All the astronauts have to lift their legs over their head as they get in their seats for the liftoff.

4:22 p.m. - The astronauts have arrived at the base of Launch Pad 39A. They can admire the spectacular sight for a couple minutes before getting into the elevator and heading up to the 195-foot level. They will take a short walkway to the White Room and Endeavour's hatch. Only a couple astronauts go inside the White Room at a time because of its size. They also board Endeavour in a specific order to best use the space inside the crew compartment.

4:15 p.m. - The astronauts are riding to the launch pad under clear skies with a hint of clouds. The weather concerns have not materialized thus far and the forecast continues to look good heading toward launch time this evening.

4:05 p.m. - STS-126 Commander Chris Ferguson leads his crew out of the Operations and Checkout Building and into the Astrovan. The Astrovan will take the seven astronauts to Endeavour on Launch Pad 39A. It will take about 30 minutes for the astronauts to reach the launch pad and make their way up to the White Room where they will board Endeavour.

4 p.m. - The countdown has resumed at T-3 hours and counting. The countdown will proceed to the T-20-minute mark where it will hold for a planned 10 minutes. There are no technical issues and the process is moving along smoothly.

3:45 p.m. - The astronauts have donned orange launch-and-entry suits in the Operations & Checkout building. The suit room is just down the hall from the Astronaut Crew Quarters inside the O&C building. The crew will soon leave the building for a ride in the Astrovan out to Launch Pad 39A where Endeavour is waiting for them.

3:25 p.m. - In the interest of scene-setting, here is a taste of what the firing rooms look like.

They are housed inside the Launch Control Center at Kennedy Space Center about three miles away from Launch Complex 39A.

Each room is big enough to house an average fast-food restaurant. Vast windows angled skyward and facing Launch Complex 39A and 39B make up one wall. Several rows of consoles near the back row are on risers like the seats in a stadium-style movie theater. This is where the launch director and senior members of the launch team sit.

A pair of small rooms separated by glass occupy each corner of the overall firing room. Senior NASA officials monitor the countdown from there.

The rest of the floor is taken by cabinets in large horseshoe patterns. This is where most of the launch team sits. Nameplates stand on each cabinet to show the controllers’ responsibility, such as the shuttle main engines.

There are about 100 controllers in the room, including the launch director and managers. Each controller has monitors and can call up camera angles covering almost every angle of the shuttle on the launch pad. They can zoom in on small areas to assess conditions during the count.

They also have numerous audio networks they can dial into to talk to other controllers and give status reports. The networks are called “loops” and controllers are known to develop keen hearing that lets them listen to several ongoing conversations at a time without losing their way. There are also several telephones around every station.

The primary firing room has computer consoles built into wood-colored cabinets that give it the look of a corporate conference room. Firing Room 3, where the Launch Blog is based for this mission, looks more like the Hollywood portrayal of control rooms in such films as "Space Cowboys" and "Apollo 13." The cabinets are blue metal and the monitors a bit smaller. PC screens and towers have been installed throughout the firing room and the controllers have the same access to audio and video loops as their counterparts in the other firing rooms.

3:20 p.m. - The weather outlook is improving and Launch Director Mike Leinbach sees little chance for interference with tonight's launch attempt. The countdown remains on schedule for a 7:55 p.m. liftoff.

3:10 p.m. - Launch day activities involve sites throughout NASA's Kennedy Space Center. The Launch Control Center is the nerve center for launch. It was designed around four firing rooms for the Saturn V moon rocket, the most powerful booster NASA ever built. The LCC, as it is called, is a four-story building standing next to the gargantuan Vehicle Assembly Building.

A vast array of cables and wiring connects the LCC with the shuttle processing hangars and the Vehicle Assembly Building so engineers in the firing rooms can perform numerous tests on the shuttles as they are readied for launch.

3 p.m. - Seven astronauts will fly Endeavour to the International Space Station. They are commanded by Chris Ferguson, a veteran astronaut who served as pilot on STS-115. He will sit in the left-hand seat at the front of the cockpit.

Eric Boe will sit in the right-hand seat at the front of the cockpit as pilot of Endeavour during Boe’s first mission. His controls are duplicates of Ferguson’s, and Boe can fly the shuttle from his position.

As the flight engineer, Mission Specialist Steve Bowen, also a first-time flier, will sit behind and between Ferguson and Boe. Mission Specialist Donald Pettit, who lived aboard the station for five months, will sit next to Bowen on the upper level of Endeavour’s crew compartment.

Three mission specialists will sit on the lower level. Veteran astronaut Heidemarie Stefanyshyn-Piper will sit closest to the hatch. Once in space, she will be the lead spacewalker for three excursions outside the orbiting laboratory.

Shane Kimbrough, who will also make three spacewalks, will sit in the middle seat during launch. Sandra Magnus will ride into orbit in the seat farthest from the hatch. She will not return aboard Endeavour, but instead remain on the International Space Station for a long-duration mission. Current station resident Greg Chamitoff will take her place aboard Endeavour.

2:55 p.m. - Endeavour stands poised for space at Launch Complex 39A. A team of technicians called the Closeout Crew is preparing for their role of getting the STS-126 astronauts into the orbiter. The astronauts will not arrive until about 4:35 p.m. Another team called the Final Inspection Team has been scanning the shuttle stack for signs of ice buildup on the external tank. They use infrared scanners and binoculars to survey the tank.

2:50 p.m. - With the launch team working no technical issues, all eyes are watching the weather. Meteorologists are tracking an approaching cold front that appears to be on pace to arrive Saturday. The forecast calls for a 70 percent chance that Endeavour will face acceptable conditions at launch time. Currently, there are only wisps of white clouds at the launch site.

2:45 p.m. - The gigantic external tank attached to space shuttle Endeavour was loaded with 500,000 gallons of liquid oxygen and liquid hydrogen this morning beginning at about 11 a.m. It took about 2½ hours to fill the tank with the propellants that fuel the shuttle’s three main engines during the 8½-minute climb into space.

A team of controllers in Firing Room 4 watched their monitors as the hydrogen and oxygen flowed into the tank. The fueling is performed by remote control, with the launch team commanding valves to open so the chemicals can run from storage tanks at Launch Complex 39A.

Pipes carry the oxygen and hydrogen to the mobile launcher platform holding Endeavour, its boosters and tank. The propellants run through a network of lines on the platform and into Endeavour’s aft compartment and then into the tank itself.

The flow reverses during launch, when all the stored propellants are siphoned quickly back into Endeavour to feed the main engines.

The controllers will continue to examine the readouts from sensors inside the shuttle and tank throughout the countdown to make sure the fuel levels remain full. The oxygen is kept at minus-297 degrees and the hydrogen is minus-423 degrees – both cold enough to liquefy into a slush. Some of the gases warm up just enough to evaporate out, however, so a trickle of oxygen and hydrogen keep flowing to the tank to replace the evaporating gas.

2:40 p.m. - The countdown is in a built-in hold at T-3 hours, but everything remains on schedule for a 7:55 p.m. liftoff. The countdown will resume at 4 p.m. and the astronauts will leave the Astronaut Crew Quarters a few minutes later to make their way to the launch pad.

2:30 p.m. - Good afternoon from NASA’s Kennedy Space Center, where space shuttle Endeavour will thunder into space in a few hours at 7:55 p.m. EST. The shuttle has been loaded with equipment and supplies bound for the International Space Station. About 14,500 pounds of cargo is inside the Leonardo module. Endeavour is also carrying a platform in its payload bay that holds a 2,000-pound device called a Flex Hose Rotary Coupler Unit.

Today’s launch blog comes from inside Firing Room 3 of the Launch Control Center at Kennedy. As the countdown moves toward liftoff, we will give you a taste of some of the activity inside the firing rooms.
