Space shuttle Endeavour due to launch @ 4.39 AM FEBRUARY 7,2010

Launch was scrubbed. Read below. Will try about this time tomorrow again.

Space Shuttle Endeavour sits on the launching pad ready to go @ 4:39 AM if the weather holds. Read launch blog below.



SCRUB!
Sun, 07 Feb 2010 04:31:57 AM EST

Endeavour will remain on the ground this morning after dynamic weather prompted the launch team to stand down for this attempt.

"We were just not comfortable with launching the shuttle tonight," Launch Director Mike Leinbach radioed to Endeavour.

The closeout crew will return to the pad to help the astronauts unstrap from their seats and leave the shuttle.

Last Night Launch on the Schedule
Sun, 07 Feb 2010 04:12:45 AM EST

This morning's launch is the last scheduled night launch of the Space Shuttle Program. The solid rocket boosters' white and orange flames light up the space center almost instantly. You could read a book by the light of the exhaust. As the shuttle rises, the brilliance extends out to other parts of the coast. The bright light also makes the shuttle easy to track as it arcs over the horizon into space. People as far north as Nova Scotia have reported seeing the shuttle head into the sky during a night launch. So if you're on the fence about whether to go out and have a look, get off the fence and go! Well, at launch time that is.

Weather Improving
Sun, 07 Feb 2010 04:08:37 AM EST

The launch team is cautiously optimistic that the weather conditions will improve as we get closer to launch time. The weather conditions are currently "green," which means they are within limits. Astronaut Chris Ferguson continues firsthand evaluations as he flies weather reconnaissance aboard the Shuttle Training Aircraft.

Countdown Enters Last Built-in Hold
Sun, 07 Feb 2010 03:45:14 AM EST

T-9 minutes and holding . . . The countdown paused as planned this morning in the last planned hold of the launch process. This hold lasts 45 minutes and allows the launch team and flight controllers to give their final readiness checks before proceeding with launch.

As they've been doing all morning, the launch team will look closely at expected weather conditions at launch time before deciding whether to go ahead with the countdown.

Countdown Resumes on Schedule
Sun, 07 Feb 2010 03:34:36 AM EST

The countdown clocks are moving again, ticking backward from T-20 minutes. Weather remains the concern for preventing a launch at 4:39 a.m.

Weather Goes Red
Sun, 07 Feb 2010 03:25:45 AM EST

The cloud ceiling forecasters have been watching tonight and this morning has moved over Kennedy Space Center and launch weather is now "red," or “no-go.” Launch procedures continue to move ahead and the countdown has entered a planned hold at T-20 minutes. There are no technical issues.

Endeavour's Hatch Closed and Locked
Sun, 07 Feb 2010 03:15:15 AM EST

Technicians closed the hatch on the side of Endeavour in one of the milestones before launch. A leak check was performed to make sure the spacecraft is sealed correctly for flight. The hatch is designed so the astronauts inside the shuttle can still get out quickly on their own in an emergency. From this point, the closeout crew will make final preps to the White Room before they leave the launch pad.

The countdown is moving ahead as scheduled for a 4:39 a.m. launch, but many eyes are following a line of low clouds expected to move in. The chance for acceptable conditions remains at 30 percent.

Closeout Crew Processing White Room
Sun, 07 Feb 2010 02:44:03 AM EST

The technicians who helped the astronauts get set inside Endeavour have taken all their materials out of Endeavour and will soon close the hatch. The closeout crew carefully inventory everything that goes into the shuttle during the strap-in work so they can be sure it all comes out before launch. Some things would be hard to miss, such as the large yellow hose that circulates air in the crew compartment. No matter the size though, everything gets inventoried and marked off on the list before the techs leave the White Room.

Weather Forecast Deteriorates Further
Sun, 07 Feb 2010 02:41:48 AM EST

Shuttle weather forecasters continue to watch a layer of low-level clouds moving from the north into the Kennedy Space Center area. The chance for acceptable conditions at launch time now is 30 percent. Astronaut Chris Ferguson will take a look at the clouds during a weather reconnaissance flight aboard the Shuttle Training Aircraft.

A Node Called Tranquility
Sun, 07 Feb 2010 02:22:54 AM EST

Endeavour's crew is carrying the last of three connecting nodes, Tranquility, to the International Space Station during STS-130. The node was named Tranquility in honor of Apollo 11's moon landing in 1969. Apollo 11's lunar module, Eagle, touched down on the Sea of Tranquility. The space station module will be connected on the fifth day of the mission. A host of life support equipment and other machinery will be housed inside Tranquility to allow the station to continue to host six-person crews.

Like other crew modules on the station, Tranquility is a cylinder with a network of wiring, plumbing and fixtures installed. The connections allow station crews to move refrigerator-sized racks into different parts of the station with ease. The racks are sophisticated networks of cables and equipment themselves. Some hold science experiments, others are loaded with life support gear. One of the racks destined for Tranquility is the COLBERT treadmill, the exercise machine named for Comedy Central's comedian Stephen Colbert. COLBERT already is on the station, but will be moved to its new home in Tranquility. Also, two water recovery racks that process everything from sweat to urine into drinkable water will be moved to its permanent place inside Tranquility.

The two other connecting nodes that make up the station are Unity and Harmony.

'Stevie Ray' Robinson Aboard
Sun, 07 Feb 2010 02:11:35 AM EST

Mission Specialist Stephen Robinson is getting into his seat on the flight deck behind and between Commander George Zamka and Pilot Terry Virts. Robinson will serve as the flight engineer for launch and landing, which means he will help the others during the climb into space. Robinson is the lead guitarist for the astronaut band "Max-Q" and is nicknamed "Stevie Ray."

With Robinson on Endeavour, the crew is complete. After the closeout crew finishes its work inside the orbiter, the technicians will climb out and close the hatch before prepping the White Room for launch and leaving the launch pad.

First-time Flier Virts in the Pilot’s Seat
Sun, 07 Feb 2010 02:07:54 AM EST

Terry Virts joined the astronaut corps in 2000 and served as lead astronaut in NASA’s T-38 program before being chosen to fly aboard STS-130. Like Zamka, Virts has controls at his station to let him fly Endeavour. Most of the time, Zamka does the flying, but Virts will get a chance to fly around the International Space Station as Endeavour leaves the orbiting laboratory. This is the first launch day for Virts, though he and the crew have practiced all the procedures repeatedly.

Hire Climbs Aboard Endeavour
Sun, 07 Feb 2010 01:55:47 AM EST

Kathryn Hire, who goes by "Kay," is moving into her place on Endeavour's flight deck. She will sit behind Pilot Terry Virts during launch and landing. Hire is one of Kennedy's own, since she worked here as a shuttle engineer before becoming an astronaut. She is also a U.S. Naval Reserve officer and went into active duty in recent years. For STS-130, she will operate the robotic arm on the International Space Station to lift the Tranquility node out of Endeavour and lock it into place on the station. She will also work the arm for the maneuvers to place the cupola in its permanent port on Tranquility.

Cloud Deck Breaking Up
Sun, 07 Feb 2010 01:47:29 AM EST

The low-level clouds that forecasters are watching appear to be scattering a bit, shuttle weather forecasters have reported. The chances for acceptable conditions at launch time remain 60 percent.

Patrick Positioned for Launch
Sun, 07 Feb 2010 01:45:58 AM EST

Mission Specialist Nicholas Patrick has taken his seat next to Behnken on Endeavour’s lower level. Patrick is a naturalized citizen who was born in England. He flew once before as part of the STS-116 crew. This time up, Patrick gets to expand his repertoire with three spacewalks to set up the Tranquility module and cupola for the space station crew.

Behnken in Place on Middeck
Sun, 07 Feb 2010 01:31:49 AM EST

Robert Behnken is strapping in on the lower level in the seat closest to Endeavour’s hatch. Although he will only get to see a bank of white lockers on the way up, Behnken will have some of the most enviable looks at Earth as he performs three spacewalks during this flight. He took part in three spacewalks during his previous mission, STS-123. That flight was also aboard Endeavour.

Commander Heads Inside
Sun, 07 Feb 2010 01:21:47 AM EST

Technicians working inside the White Room at Launch Pad 39A have put the finishing touches on George Zamka’s pressure suit, including the communications carrier sometimes called a “Snoopy cap.” So Zamka is making his way to the commander’s station at the left-hand seat at the front of the flight deck. One of Zamka’s hobbies, weight lifting, probably comes in handy here as he has to lift himself into the seat because Endeavour is on its tail for launch. Because of that arrangement, all the astronauts lay on their backs with their feet above their heads for about three hours before liftoff.

Astronauts to Take Seats in Shuttle Momentarily
Sun, 07 Feb 2010 01:14:38 AM EST

The six astronauts of Endeavour are up on the 195-foot level of the launch tower at Launch Pad 39A before walking across the metal bridge that leads to the shuttle's hatch. Zamka, as commander, gets to climb inside Endeavour first. A technician will follow him into the shuttle to help him get into his seat and strap him into place. While he is getting into place on the upper level of the shuttle's crew compartment, Robert Behnkenwill take a seat on the lower level. The crew will continue from there with one person heading up to the upper level and one on the lower level until they are all aboard.

Weather Watch Continues as Countdown Moves Ahead
Sun, 07 Feb 2010 01:02:44 AM EST

At T-2 hours, 41 minutes and counting, weather remains the most pressing concern leading up to launch. Forecasters are watching a line of low clouds north of the space center. The official prediction remains at a 60 percent chance of acceptable conditions at 4:39 a.m. While we wait on the weather, the launch preps are moving ahead on time and the astronauts are making their way to Launch Complex 39A where Endeavour awaits.

Crew Steps into Astrovan
Sun, 07 Feb 2010 12:51:13 AM EST

George Zamka led his team of six astronauts from the Operations and Checkout Building into the Astrovan. They strolled out to greet space workers and others on their way to the vehicle that will take them to the launch pad. From there, it will be an elevator ride up to the 195-foot level of the fixed service structure. A quick walk over a metal bridge will take them to the White Room where they will put on their last bits of gear before climbing inside Endeavour. The crew walkouts have an excitement in the air like a rock concert, but without the smoke machines and lasers.

Astronauts Suit Up for Flight
Sun, 07 Feb 2010 12:28:47 AM EST

The six crew members of space shuttle Endeavour are getting into their orange pressure suits. Working inside the Operations and Checkout Building here at Kennedy, the astronauts and technicians are following a carefully scripted process for getting into the so-called “pumpkin suits” and then checking them for leaks. The suits include a layer of liquid-cooled underwear beneath the orange shell. Astronauts since the Gemini program have suited up in the same room, including those of Apollo.

Forecast Deteriorates a bit, Zamka Reviews Weather
Sun, 07 Feb 2010 12:16:35 AM EST

Forecasters have lowered the chances of acceptable conditions to 60 percent after determining there is a risk of low clouds blowing in near launch time. Weather reconnaissance flights will begin soon to evaluate conditions firsthand.

George Zamka, commander of STS-130, is going over the weather conditions with Flight Director Norm Knight during a weather briefing before he gets on his pressure suit. Pilot Terry Virts and Mission Specialist Stephen Robinson, who is the flight engineer for launch, also are listening to the briefing. There are no surprises in this briefing and the crew is being advised of the expected conditions, including the concerns for high winds. The outlook also includes a look at the weather over emergency landing fields in France, Spain, California and New Mexico.

Launch Control Center Drying Out
Sun, 07 Feb 2010 12:07:14 AM EST

The launch team has been handing out thanks this week to workers who brought in fans, trailer-sized blowers and many feet of hoses to dry out the Launch Control Center after a fire protection system pipe burst and released thousands of gallons of water into the building last weekend. The firing rooms were ready for the countdown and the launch was not delayed. The drying process is not complete, but the LCC still is able to do its job.

Six Accomplished Astronauts
Sat, 06 Feb 2010 11:49:50 PM EST

George Zamka is making his second flight to the International Space Station, the first was STS-120 in 2007. Zamka is the commander of this flight, having served as pilot on STS-120. Coincidentally, the STS-120 mission took a node up to the station, too.

Terry Virts, making his first flight, is the pilot for Endeavour. He will oversee shuttle systems and robotic arm work. He also gets to outfit Tranquility and the cupola during the 13-day mission.

Nicholas Patrick flew previously on STS-116 and is slated to make three spacewalks during this flight. His exemplary education includes a doctorate in mechanical engineering from the Massachusetts Institute of Technology.

Robert Behnken will add three spacewalks to the three he performed during STS-123 in 2008. During the previous mission he operated the station's robotic arm and the newly installed robotic hand called Dextre.

Stephen Robinson is the most experienced of the STS-130 crew. He first flew in 1997, and last went into space as part of the Return to Flight crew of STS-114 in 2005.

Kathryn Hire, known as "Kay," knows Kennedy Space Center quite well. She worked as an engineer at the spaceport for five years before joining the astronaut corps. She flew on Columbia in 1998 during the STS-90 mission.

Shuttle Fueled for Launch
Sat, 06 Feb 2010 11:40:11 PM EST

The huge thermos bottle that is the shuttle's external fuel tank has been filled with about half-a-million gallons of liquid hydrogen and liquid oxygen. Both propellants are chilled well below freezing, with the hydrogen temperature at minus 423 degrees F and the oxygen at minus 297 degrees. The fueling went smoothly, although the process did not begin until teams could adjust the cabin air pressure regulator on the fixed service structure. Tanking operations began at 7:47 p.m. and concluded at 10:47 p.m.

Naturally, a Florida winter can't keep the chemicals that cold on its own, which is why the tank is coated with a thick layer of insulation. The fuel and oxygen that evaporate during the countdown is steadily replaced until just before liftoff. Endeavour's three main engines burn the liquid oxygen and hydrogen during the shuttle's 8 1/2-minute climb into orbit.

In case you're curious why NASA goes through the trouble of handling cryogenic propellants, it's because liquids take up less space than gases. The engines vaporize the oxygen and hydrogen before mixing them together and burning them to create the characteristic pale blue shock diamonds seen at liftoff.

Weather Outlook 80 Percent Go
Sat, 06 Feb 2010 11:33:38 PM EST

It's expected to be chilly at launch time here on Florida's Atlantic coast, but forecasters’ main concern are winds gusting above limits and the possibility of low clouds moving over the launch site. Shuttle Weather Officer Kathy Winters puts the odds of acceptable conditions at launch time at 80 percent.

First Shuttle Launch Day of 2010 Begins!
Sat, 06 Feb 2010 11:29:56 PM EST

Welcome to NASA's Launch Blog for the STS-130 mission! We are about five hours from liftoff of space shuttle Endeavour on a construction flight to the International Space Station. Endeavour is carrying the Tranquility node and a seven-windowed cupola that promises the best views of Earth without going on a spacewalk. There are no technical issues standing in the way of a launch at 4:39 a.m. Weather is looking good for launch although it is brisk by Florida standards.

The six astronauts of STS-130 will be climbing into their orange pressure suits in about 40 minutes and they will make their way out to the launch pad after that. We'll hit on that and other milestones during today's coverage from inside Firing Room 3 in the Launch Control Center at Kennedy. We'll also let you know if anything comes up that could delay a launch, but all looks good right now.

With Tank Filled, Launch Countdown on Schedule
Sat, 06 Feb 2010 11:11:46 PM EST

The shuttle's fueling operations have gone smoothly this evening and everything is on schedule for a liftoff on time at 4:39 a.m. Our continuous coverage of the countdown to the launch of Endeavour on mission STS-130 will begin in about 20 minutes. See you at 11:30!
