NASA Sets May 16 for Last Launch of Endeavour; Atlantis Slips to July

Space Shuttle Endeavour is now set to launch on May16 at 8:56 a.m. EDT from Pad 39 A following launch scrub on April 29, 2011. Critical APU fuel line heaters in the aft section of the orbiter failed in the final hours of the countdown. This close up view was taken while I was standing next to the orbiter in March.

KENNEDY SPACE CENTER – NASA managers set May 16 as the new launch date for the final flight of Space Shuttle Endeavour after technicians completed work to rewire and retest a switchbox in the orbiters aft compartment. Shuttle managers ordered the repair work following a heater malfunction that forced NASA officials to call off the planned April 29 launch.

At a briefing for reporters today (May 9) at NASA’s Kennedy Space Center in Florida, Shuttle managers Mike Moses and Mike Leinbach announced that Endeavour’s last liftoff is now targeted for 8:56 a.m. EDT on Monday, May 16.

“Right now, we’re in good shape,” said Shuttle Launch Director Mike Leinbach.

“Endeavour’s looking good, the team is upbeat. I went to the meeting this morning and they’re ready to go. Hopefully, this time the heaters will work and we’ll be able to launch on time next Monday morning.”

The STS-134 mission is the penultimate flight of the space shuttle program and will deliver the $2 Billion Alpha Magnetic Spectrometer to the International Space Station.

Endeavour’s last launch attempt on April 29 was scrubbed about four hours prior to blastoff when critical hydrazine fuel line heaters failed to turn on inside one of the orbiters three auxiliary power units (APU’s).

Technicians have been working around the clock to resolve the problems and determined that the likely cause of the heater failure was an electrical short inside the ALCA -2 load control assembly box located in the aft section of the shuttle (see photo).

They installed about 20 feet of new wiring, a new ALCA box and then retested all related systems over the past week and a half.

“We’ve replaced everything except the heaters, and we’ve wrung those out with at least five separate checks and full functionals afterwards and now have extremely high confidence that the problem is no longer on the ship or in any of the electronics,” said Mike Moses, the Shuttle launch integration manager at the Kennedy Space Center.

The APU’s control the shuttles hydraulics which power the steering of the main engines, wings, wheels and rudders during ascent and re-entry. The three units must all be fully functional before NASA can commit to any shuttle launch as part of the launch commit criteria (LCC). If the heaters fail during flight, the hydrazine can freeze and clog the fuel lines and render the hydraulics inoperative. A rupture in the lines could result in toxic hydrazine leaking into the shuttles aft engine compartment.

The potential launch window for Endeavour’s final flight extends through May 26, except for May 21.

The all veteran six man crew led by Shuttle Commander Mark Kelly is due to fly to the Cape on Thursday, May 12 from their training base in Houston. The STS-134 mission has been officially extended to 16 days from 14 days and will include 4 spacewalks.

The launch countdown will commence on Friday, May 13 from the beginning of the nominal 41 hour countdown sequence.

As a consequence of Endeavour’s delays, the launch of the very final shuttle mission of Space Shuttle Atlantis will likely be delayed to mid-July, although Moses and Leinbach did not give a specific target date.

How a Rubber Chicken is Spreading the Word about NASA, Space Missions and Science

Here’s a headline you don’t see too often: “Rubber Chicken Turned NASA Mission Mascot Embarks on a Flight to Space.” Seriously, this is a true story. If you’ve not heard of Camilla Corona, or Camilla SDO as she is sometimes called, you probably haven’t been paying attention to one of the most exciting current space missions, the Solar Dynamics Observatory. Camilla is virtually everywhere in the world of social media, and she travels around the country – and the planet – spreading the word about what’s going on with our Sun and how SDO is helping us learn more about it. As mission mascot, she is leading the way – and setting the bar pretty high for other NASA missions to follow – about how to get the public interested in space and science.

“People ask, ‘what does a rubber chicken have to do with a science mission?’ but as long as we get people’s attention, we can then divert it to what SDO does,” said Romeo Durscher, Camilla’s PR assistant and ‘bodyguard.’ “However, we didn’t know it would go this far when we started this.”

The story of Camilla goes back to the early days of SDO at Goddard Space Flight Center, when mission scientist Barbara Thompson introduced Camilla as something funny for the science team.

“Barbara was very persistent – she brought little Camillas and rubber chickens to all the science meetings to lighten up the room,” Durscher said.” The question always is, ‘why Camilla?’ and the official answer is because she is the same color as the sun. Over the years, Camilla has just become more and more integrated into the education and public outreach side of the mission.”

“Camilla started as an inter-office joke and soon became the mascot for the science side of the mission,” said Aleya Van Doren, the formal education lead for SDO. “It is not uncommon for someone who has been working on SDO for awhile to receive a rubber chicken as sort of a ‘you’ve earned your keep’ award. She’s a great moral booster for the science team, as well as being a wonderful ‘hook’ to get the public interested in the mission.”

Van Doren said the fun part is bringing Camila to public events or classrooms. “She is a great conversation starter with kids, especially with elementary children. Our main focus is getting the science out to the public, so whatever means we can use to draw in people’s interest and see the amazing things that SDO is doing, we consider it worthwhile.”

I’ve personally seen children — as well as adults — literally melt when meeting Camilla and get very excited about interacting with her.

As far as the public side of things, Van Doren said they are pleasantly surprised at the amount of attention her social media channels on Twitter and Facebook have been bringing to the mission.

“Romeo does a great job bringing her around to various places. Her schedule is quite full for a chicken. I would be really tired if I was that busy,” Van Doren said.

Which begs the question: just how many Camillas are there?

“That is a guarded secret,” Van Doren said, “but there is really only one official Camilla. We are very careful to make sure she is only in one place at a time. But sometimes airfare gets expensive, so she’ll have a body double in one place. Jet-setting around the country can sometimes be difficult.”

Durscher is the keeper of what is now the official Camilla, but confirmed that she does indeed have some body doubles. At first, it was easy to have Camilla be in several places at once. That was before she started wearing clothes.

“Our rubber chicken had the SDO mission pin on her left side, and that was Camilla,” Durscher said. “We had one at Goddard, one at Stanford University, and another at our education office, so there were several Camillas, and we had the story that she was travelling here and there, but now it gets a little more complicated.”

Cynthia Butcher, a fan of Camilla, knits specially made outfits for a rubber chicken, including a spacesuit, a Star Trek uniform, an “I Dream of Jeannie” outfit, and many more.

“Cynthia is a wonderful person, one of the first followers of Camilla on Twitter and Facebook,” Durscher said. “She really enjoyed what Camilla was doing, and said that Camilla should have a flight suit and that she would make her one. When we got the outfits, we were thrilled. But now we have to have a storyline for why we sometimes we might see Camilla without any clothes on – maybe the suit will be in the dry cleaning, or something.”

Camilla has met astronauts, trained at Johnson Space Center, attended World Space Week in Nigeria and a science fair in Malaysia, been on hand at many NASA Tweet-ups and launches, and even given a speech at the Smithsonain Ignite event at the Smithsonian Museum – well, actually Durscher ended up speaking for her, as Camilla lost her voice shouting at all the animals in the Washington DC Zoo the day before.

But Camilla’s main goal is to educate, inspire (especially to inspire girls to go into science and engineering) to build community and have fun — as well as bringing the beautiful, stunning and wonderful images and data from SDO into the classroom.

“We have lots of things teachers can use to educate their students about the Sun — hands-on experiments, beautiful images — and students can have the opportunity interact with mission scientists,” Durscher said.

Camilla and her crew pose with the poster for the BTS-1 (Balloon Transport System).

But now Camilla embarks on what might be her greatest adventure ever. She is actually going to space. Camilla will be going to the edge of space in a weather balloon with a camera for the Camilla Space Weather Project.

“We are using that launch as the hook for new program we are doing to get the public interested in space weather forecasts,” said Van Doren.

Space weather refers to conditions on the Sun and in the solar wind that impact Earth’s atmosphere and can influence space and ground based technology and even human health.

“We have a page of a series of questions that people can go through to make a prediction of whether a space weather event is going to take place – such as the bright flares SDO has observed recently, and if those events will affect Earth, such as auroras being visible, or if it could cause any problems with satellites or related technology,” said Van Doren.

Launch is currently scheduled for this weekend, May 8 from the University of Houston central campus. Launch preparations begin at 10 AM, and will be webcast on UStream.

“We want to make sure that when Camilla launches it will be safe, so we’ve been having people make a space weather forecast and see whether or not it will be good conditions for launching to the upper atmosphere. Of course we don’t want Camilla to be bombarded with radiation, so classrooms have been making recommendations if this will be a good time to go or not,” Van Doren said.

Durscher said that as of Friday, the mission was go.

Camilla is not going to space alone. She’s traveling with Fuzz Aldrin from “Bears on Patrol” which provides US police officers with free teddy bears to use in cases involving small children, as well as a stuffed pig, Skye Bleu, the STEM (science technology engineering and math) outreach mascot for the American Institute of Aeronautics and Astronnautics (AIAA) and a patch to represent Smokey Bear.

“Our goal is to inspire the next generation of engineers, scientists and explorers,” Durscher said, “and we’ll make sure that Camilla and her crew will come back alive.”

Let’s hope so. Camilla has lots more work to do spreading the word about NASA, space and science.

Me and Camilla.

Rare and Unpublished LIFE Photos of Alan Shepard’s Historic Flight

If you follow me on Twitter, you may have seen how I was oohing and aahing about a wonderful set of rare and never-seen photographs of Alan Shepard, John Glenn, and the other Mercury astronauts released by LIFE.com in honor of the 50th anniversary Alan Shepard’s flight on May 5. Maybe LIFE saw my Tweets, too, as they contacted us, giving Universe Today permission to publish a few. Above, Shepard strides to the launchpad early on May 5 1961, with Gus Grissom close behind. Shepard reportedly joked to technicians who rode with him to the launch pad: “You should have courage and the right blood pressure” if you want to succeed as an astronaut. “And four legs … You know, they really wanted to send a dog, but they decided that would be too cruel.” In Shepard’s right hand: a portable air conditioner to cool the inside of his pressure suit before he enters the capsule.

In this previously unpublished photo, John Glenn crouches near Shepard’s capsule, Freedom 7, prior to launch. In the book “Light This Candle: The Life and Times of Alan Shepard,” author Neal Thompson portrayed the fierce competitiveness between Shepard and Glenn over who would be the first astronaut in space, which sometimes bordered on the two disliking each other. But as the first flight approached, Shepard and Glenn spent a lot of time together training, and formed a bond. Glenn even put a few items in Shepard’s Freedom 7 capsule as a joke to lighten the intensity of the day, and this image shows Glenn’s excitement and joy as his fellow astronaut enters the spacecraft. LIFE photographer Ralph Morse said of NASA’s choice for who was making the first flight: “You know, I presumed, at that point, that they were saving Glenn, that having him circling the Earth for the first time would be better press for NASA. But you don’t know about these things. They had their own reasons, of course — complicated reasons, based on skills and personality and temperament — for choosing one man ahead of another.”

This previously unpublished image shows Shepard’s Redstone rocket before liftoff. “I never have been my own favorite subject,” Shepard once told LIFE, when asked how he felt about the rewards and dangers inherent in Project Mercury. “And I don’t think I’ve found anything new about myself since I’ve been in this program. We were asked to volunteer, not to become heroes. As far as I’m concerned, doing this is just a function of maturity. If you don’t use your experience, your past is wasted, and you are betraying yourself.”

This is my absolute favorite image of this set: Shepard shares a laugh with fellow astronauts Gus Grissom (right) and Deke Slayton upon his arrival at Grand Bahama Island, shortly after his successful flight and splashdown. Oh to be a fly on the wall to know what they were laughing about!

No internet, no instant messaging, no Twitter or Facebook. The Mercury astronauts and the rest of the world had to wait for the next day’s newspapers to come out to read of Alan Shepard’s heroics. “Though the U.S. still has far to go to catch up with the Russians in space,” LIFE magazine noted in its May 12, 1961 issue, “Shepard went a long way toward lifting American heads higher.”

Alan Shepard: Complicated, Conflicted and the Consummate Astronaut

[/caption]

50 years ago today, Alan Shepard blasted off on board the first flight of NASA’s Mercury program, becoming the first American in space. Shepard was the consummate astronaut, — he stayed with NASA for over 15 years, and eventually walked on the Moon. But for all his successes, Shepard was a complicated and conflicted man; even though he was in constant limelight along with all of the early NASA astronauts, his life was somewhat of an enigma, as he closely guarded his privacy and held most people – including his friends – at arm’s length.

“He was the epitome of the image that NASA had hoped to portray when they selected the first astronauts,” said Neal Thompson, author of the only Shepard biography, “Light This Candle: The Life and Times of Alan Shepard.” “He was a aircraft carrier pilot, a test pilot, drove fast cars, smoked cigars, drank martinis—he was stylish and cool and cocky. I’ve described him as Don Draper in a spacesuit. He represented that “Mad Men” era – cool and suave and all that.”

But, Thompson said, that was an image that Shepard worked hard to portray as well as protect, and Thompson felt there had to be more to Shepard’s story. Through years of research, Thompson found Shepard to be a much more compelling man than he ever expected.

“He wasn’t the most outgoing guy with the press and I felt like there had to be more to his story than what I had read,” Thompson told Universe Today. “There were a lot of aspects to his personality that were complicated and compelling and contradictory. He was highly competitive, but he was also a softy underneath at times. He was accused over the years of being a bit of a womanizer, and yet he was married to the same woman for 40-plus years and I think they were very devoted to each other. So there were a lot of complex aspects to his personality that were fun to explore.”

While all the other Mercury 7 astronauts had either written their own books or had books written about them, America’s first astronaut had not told his own life story, and no one had gotten close enough to tell it for him. Shepard died without ever authorizing a biography that focused on his life.

“I was really intrigued when I started researching his life that, no other biography had been written about him,” Thompson said.

The title of the book, which was first published in 2004, refers to Shepard’s impatience with NASA engineers who were making sure his Redstone rocket was ready to go. Shepard was frustrated: he knew very well he could have been the first human in space, if not for political and technical delays. But as it was, cosmonaut Yuri Gagarin launched on an orbital flight on April 12, 1961, becoming the first man in space and scoring a huge victory for the Soviet Union in the Cold War with the US.

23 days later, Shepard sat on the launchpad, waiting inside his rocket for over 4 hours while engineers tackled one problem and then another. The wait was longer than anyone expected and Shepard ended up having to urinate inside his spacesuit, claiming otherwise his bladder would burst.

Finally, when one more problem cropped up, Shepard exclaimed, “Why don’t you fix your little problem and light this candle?”

“I think that sums up his character in many ways, that one particular quote,” said Thompson. “He was a very intense guy who just wanted to get the job done and liked to move forward and not look back, and I think that reflection of that intensity of his personality is nicely summed in those few words.”

Shepard’s whole life was about competition. “Whether it was in sports as a youth, or competing among other naval aviators when he was a carrier pilot,” said Thompson, “and then it just sort of ramped up at each stage of his career, becoming a test pilot where he competed with some of the best aviators on the planet and then to be selected among this extremely elite group of Mercury 7 astronauts and then to compete against them for that first ride. But I think he thrived on that and it was fun to explore what that meant in the scope of the space program.”

Particularly intriguing to Thompson was the competitive relationship between Shepard and John Glenn, who early on were pegged as being the two astronauts who were most likely to fly first.

“As you know, Shepard was picked first and Glenn was furious about that,” Thompson said. “I think it is sort of interesting that now, historically, Glenn is more well known probably than Shepard, even though he was picked to fly third among the first astronauts. But because he has the orbital flight, Glenn’s flight is historically viewed as the bigger accomplishment.”

Shepard always kept a distance between himself and others. While he could be pulling a prank or making a joke one minute, the next he could be sullen and withdrawn or downright angry and unpleasant — which Thompson said was perhaps a way to keep the competition at bay.

But Shepard’s competitive nature is likely what made him so successful throughout his career, and in particular it was something he relied on in the mid-1960’s when he was grounded because of a disabling medical condition, Ménière’s disease, which causes severe vertigo and nausea, which is crippling for a pilot and astronaut.

“After his Mercury flight, he was selected to command the first Gemini mission, and while training for that was felled by Ménière’s disease,” Thompson said. “I think at that point, Shepard just considered hanging it up and leaving the space program and pursuing other things, like business or politics or something high profile.”

While Shepard could have anything he wanted — there were many offers he could have taken, Thompson said – he decided to stick with the program, to stay with NASA, to take on this lesser role as head of the astronaut office.

“It had to be really demoralizing for him to be the first American in space and then not be able to fly at all and to be stuck watching the other astronauts fly ahead of him. But it was always impressive to me that he did stick with it, he got his inner ear disorder cured, and fought his way back into the flight rotation and then was assigned to Apollo 14,” Thompson said.

But the disease may have saved his life from tragedy, as well. Shepard likely would have been chosen to lead Apollo 1 and was originally scheduled to command Apollo 13.

Thompson added that it says a lot about Shepard’s character that he managed to get assigned to command an Apollo mission and fly Apollo 14 so successfully.

Shepard stayed with NASA for 15 years which is longer than any of the other Mercury 7 astronauts, and longer than many astronauts today stay. “I think he really believed in the mission and believed in what he and what NASA was doing,” Thompson said.

What people might remember most about the Apollo 14 mission is Shepard hitting golf balls on the Moon.

“I think he viewed that as something that he wanted to do, maybe so that his flight could be remembered as being a little more unique than some of the others,” Thompson said. “It was a little bit of flair and maybe a sign of exuberance, punctuating his comeback and his successful flight, and he set things up so that he would only hit the golf balls at the end of the flight if everything went well. It was his kind of exclamation point tacked on to the end of Apollo 14 to say, “I did it” and here’s something fun and extra.”

Later Shepard was successful in business, becoming the first millionaire astronaut. “I think he enjoyed the rest of his life, business, traveling, playing golf, he loved his wife – he just lived a big life,” Thompson said.

Shepard died from cancer at age 74 in 1998. Tragically, his wife Louise died five weeks later from a heart attack during an airplane flight. It almost was if she couldn’t live without him.

“Shepard was almost larger than life – he always had that ‘little extra’ and he was an exceptional man at all levels,” Thompson said.

Alan Shepard and MESSENGER Stamps Unveiled at Kennedy Space Center Ceremony

KENNEDY SPACE CENTER – 50 Years ago this week, Alan B. Shepard became the first American to be launched into space. Shepard blasted off on May 5, 1961 from Cape Canaveral, Florida. NASA and the US Postal Service honored Shepard’s historic achievement today (May 4) at an Official First-Day-of-Issue dedication ceremony at NASA’s Kennedy Space Center in Florida.

Alan Shepard was one of the seven Project Mercury astronauts – who will be collectively known for all eternity as – “The Original 7”.

The US Postal Service simultaneously released two new 44 cent Forever Stamps at today’s commemoration, which bookend two historic space achievements – Shepard’s inaugural manned spaceflight aboard the Mercury capsule and NASA’s unmanned MESSENGER mission which recently became the first probe from Earth to achieve orbit about the Planet Mercury.

Fellow Mercury Astronaut Scott Carpenter attended the ceremony and unveiled the stamps along with Steve Masse, United States Postal Service Vice President of Finance at the Rocket Garden at the KSC Visitor Complex.

“Today we celebrate the 50th anniversary of many, many important issues, among them is the first steps from the home planet that were taken by the family of man,” said Carpenter.

Although Shepards suborbital flight aboard the one man “Freedom 7” Mercury capsule lasted barely 15½ minutes, the flight ignited America’s Moon landing effort and propelled American Astronaut Neil Armstrong to become the first human to set foot on the moon on July 20, 1969 during the Apollo 11 mission – one of the crowning technological achievements of the 20th Century.

The success of “Freedom 7” emboldened President John F. Kennedy to declare that America “should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the Earth,” just three weeks later on May 20.

“That was largely a response to Alan’s success,” Carpenter told the crowd of assembled officials, journalists and visitors. Also on hand for the stamp dedication was Shepard’s daughter Laura Shepard Churchly; Charles Bolden, NASA Administrator and former shuttle astronaut; Bob Cabana, KSC Director and former shuttle astronaut; and Jim Adams, NASA deputy director, Planetary Science.

“A decision was made not to put 44 cents on the stamp, but it is forever,” Carpenter emphasized. “It is appropriate to the time we should honor and remember Alan B Shepard and Freedom 7.”

Shepard’s tiny capsule measured just six feet by six feet, reached a maximum speed of 5,100 MPH, roughly eight times the speed of sound, and a zenith of 116 miles above the Earth. Freedom 7 was bolted atop a Redstone rocket that generated only 78,000 pounds of thrust, followed a ballistic arc and landed 300 miles down range in the ocean.

“These stamps, which will go out by the millions across this country, are a testament to the thousands of NASA men and women who shared dreams of human spaceflight and enlarging our knowledge of the universe,” said Bolden.
Shepard’s flight and MESSENGER both blasted off from launch pads quite close to one another at Cape Canaveral Air Force Station which is adjacent to the Kennedy Space Center.

On Thursday May 5, watch for my on site coverage of NASA’s special ceremony marking the 50th Anniversary of Shepard’s milestone “Freedom 7” mission – and an interview with Scott Carpenter.

Shepard’s mission came barely three weeks after Cosmonaut Yuri Gagarin became the first human to orbit the Earth. The bold flights of these brave Cosmonauts and Astronauts – backed by a few insightful political leaders – began the Era of Human Spaceflight. As the shuttle program winds to a close, the future of US Human Spaceflight is very uncertain.

USPS Commemorates Spaceflight Past and Present

Postage stamps honoring Mercury astronaut Alan Shepard, America’s first man in space, and NASA’s MESSENGER probe, the first spacecraft to orbit Mercury, will be presented on May 4th at a public event taking place at the Aviation Heritage Park in Dayton, Ohio.

The first stamp salutes NASA’s Project Mercury, America’s first manned spaceflight program, and astronaut Alan B. Shepard, Jr.’s historic sub-orbital flight on May 5, 1961 aboard the spacecraft Freedom 7.

The other stamp highlights NASA’s MESSENGER spacecraft currently exploring the planet Mercury. It successfully established orbit around the planet on March 18, 2011, the first spacecraft ever to do so.

These two historic missions frame a remarkable fifty-year period in which the U.S. has advanced space exploration through more than 1,500 manned and unmanned flights.

Both stamps were designed by professional artist Donato Giancola of Brooklyn, NY, who based the stamp designs on NASA photos and images.

Both stamps will be issued as “Forever Stamps” for use in mailing a one-ounce letter. Regardless of when the stamps are purchased and no matter how postage prices may change, these stamps will always be equal to the current First-Class Mail one-ounce price.

Behind the Scenes at SpaceX’s Space Launch Complex 40

CAPE CANAVERAL – Space Exploration Technologies (SpaceX) took members of the media on a tour of Launch Complex 40, where the NewSpace firm has successfully launched two of its Falcon 9 rockets and one of its Dragon spacecraft (the first entity other than nations or government bodies to do so). For the media, this tour was an eye-opening experience.

SpaceX had obviously worked long and hard to allow the world to get a grasp what it is that they are doing – while at the same time avoiding International Travel in Arms Regulations (ITAR) related issues. In a well-choreographed affair the tour was split into two separate groups, one checked out the Falcon 9 hangar, while the other group inspected the launch pad that sent last December’s Falcon 9 flight on its date with history.

One enters the hangar and is greeted by the impressive site of nine Merlin engines facing them – the business end of the next Falcon 9 rocket being prepped for launched. Despite the eye-candy on display it is the simple elegance of what is described that sells this place. The horizontally integration system allows the rocket to be extremely mobile (about four people could move one of the rocket’s stages around). The system’s frictionless design is what allows SpaceX such ease of mobility.

“Our concept of operations is unlike anybody else’s that is flying these days with the exception of the Russians and maybe Sea Launch,” said SpaceX’s Director of Mission Assurance and Integration Scott Henderson. “We use horizontal integration, we will build an entire booster here in the hangar so you have the first stage and the interstage are here now, the second stage will arrive, the Dragon and trunk will arrive and we’ll put all that together, test it inside the hangar and then when we are ready to roll out for launch we’ll open this hangar door, you saw the vertical transporter-erector outside, that would lower down on pistons, we’d roll that whole structure…into the hangar drive the transporter-erector beneath the rocket, then roll out to the launch pad and lift it vertical.”

After this segment of the tour wraps up we move outside to the launch pad. The most striking contrast to other launch sites at Kennedy Space Center and Cape Canaveral Air Force Station is that it isn’t vertically-based. Rather the Falcon 9 rolls out horizontally and is moved into the vertical position much in the same way as the Russian Soyuz and Progress vehicles are. Also, the launch pad has been simplified, this highlights SpaceX’s philosophy as well as helps the company. If something does get damaged during launch, it requires minimal effort to repair and reset the launch pad for the next mission on the horizon.

KENNEDY SPACE CENTER – The final launch of shuttle Endeavour will be further delayed, perhaps by a week or more – to May 6 or 11 time frame – as technicians working at the pad seek to determine the cause of the failure of multiple heaters in auxiliary power unit-1 (APU) which caused the scrub of Endeavour’s launch attempt on Friday, with just 4 hours remaining in the countdown. The six man crew of Endeavour had just departed for the launch pad inside the Astrovan and was forced to turn around soon thereafter. We saw them pass us by, heading back to crew quarters to await a resolution of the issues.

The launch delay came as a huge disappointment to NASA and the enormous crowd estimated at 750.000 people who came to Florida to watch the momentous liftoff in person for what many call a “life changing experience”. Even President Obama and the entire first family were on hand to witness Endeavour’s launch. But the top priority is to launch the shuttle safely and the launch team emphasized that they made absolutely no changes to the countdown procedures.

On Saturday, technicians gained access to Endeavour’s aft fuselage which houses the components suspected to have malfunction and found that the cockpit control fuse panel is working. They also verified that thermostats associated with the failed APU heaters are still not working. This indicates that the root cause of the malfunction lies deeper inside the orbiter and it will take longer for technicians to access and fix whatever is causing the problem.

APU-1 is located on the left side of the orbiter in the aft section behind the end of the payload bay.

The heaters play a critical role in keeping the APU hydrazine fuel from freezing in orbit and remain in a fluid state. If the hydrazine were to freeze and then thaw back to a liquid, it would expand and potentially rupture the fuel lines with devastating consequences.

The orbiter has three APU’s. Only one is required to fly safely. Three units provide redundancy and all must be in working order before launch. Otherwise the launch commit criteria would be violated, forcing a launch scrub. The APUs provide the hydraulics to maneuver the main engine nozzles, elevons, rudder, body flap, landing gear brakes and nose wheel steering system.

Technical teams got to work inside the orbiter on Saturday after the rotating service structure was rolled back around the orbiter to enable access. If the problem is deeper within the orbiter at the Load Control Assembly it will take several additional days to fix the problem. Retesting of any new components inside the LCA will take at least 48 hours. Furthermore if any ordnance needs to be disconnected, a further delay of multiple additional days is inevitable.

In order to launch Endeavour on Monday, May 2, at 2:34 p.m. EDT, NASA must resume the countdown on Sunday afternoon. NASA only has until May 4 to get Endeavour off the ground until they would be forced to stand down to make way for the May 6 blastoff of an Atlas V rocket carrying an Air Force early-warning missile detection satellite.

NASA officials are in touch with Air Force officials to determine if the Air Force could be flexible in changing their launch date in the event that Endeavour would be ready to launch on the blackout dates of May 5 to 7.

NASA will hold a news briefing at 2 p.m. on Sunday to update reporters on the situation.

KENNEDY SPACE CENTER, April 28 – All systems are GO here at the Kennedy Space Center as the countdown clocks tick down to the final launch of Space Shuttle Endeavour. Supercool cryogenic fuels are now being loaded into the External Tank as of Friday morning. The STS-134 launch is slated for Friday, April 29 at 3:47 p.m. EDT.

Stormy weather, heavy rain and hours of crackling thunder passed over the launch pad Thursday evening and it was very uncertain if the launch could take place as scheduled on Friday. NASA technicians were pulled back from checking the shuttle stack for any signs of damage during the thunder strikes. Luckily there were no thunder strikes with ½ mile of the pad and no damage to the shuttle or the pad launch systems.

Update Note: Progress 42 P just docked at the ISS friday morning:

Universe Today photographer Alan Walters told me that hail fell late Thursday in nearby Titusville, just 12 miles from Shuttle Launch Pad 39 A while I was at the KSC Press Site some three miles away from the pad.

Shuttle launch officials delayed the retraction of the massive Rotating Service Structure (RSS) which protects the orbiter from bad weather and flying debris. RSS retraction had been planned for 7:00 p.m. and finally started just before midnight. The RSS must be pulled away from the orbiter soon in order to commence loading of the cryogenic liquid oxygen and liquid hydrogen fuel into the External Tank.

At Thursdays news briefing, NASA Test Director Jeff Spaulding said that the countdown was proceeding well with no technical problems of any significance. The weather was the only concern with a forecast of 70% favorable conditions due to the potential for exceeding the launch criteria for cross winds.

“Everything’s going well out at pad A,” he said. “We don’t have any issues right now that we’re tracking.”
Local official expect massive crowds of tourists and onlookers numbering 700,000 or more and massive post launch traffic jams.

If you come to the launch bring lots of food and water and expect a LONGGG wait going home or to your hotels. So bring some entertainment and enjoy the shuttle show. The Shuttle launch team is ecstatic and proud that the public is responding with overwhelming interest in this uniquely American enterprise.

The primary task of the STS-134 mission is to deliver the $2 Billion Alpha Magnetic Spectrometer to the International Space Station which. AMS is a particle detector searching for dark energy, dark matter and anti matter to elucidate the birth of the Universe.

Over the next few weeks, skywatchers will have excellent viewing opportunities for the NanoSail-D solar sail.

The satellite is coming to the end of its 95-day mission to test the viability of de-orbiting decommissioned satellites or space debris. NanoSail-D is now de-orbiting and slowly losing altitude in the Earths thin upper atmosphere.

As the satellite descends, viewing opportunities will improve.

To see NanoSail-D pass over, you will need to know exactly when it will be visible from your location. To do this, go to Heavens-above.com or Spaceweather.com where star charts with times and pass details will be displayed after you enter your observing site.

Once you know the time and location in the sky of the pass of the satellite, make sure you are able to get a good view of the part of the sky where the satellite due to appear. Give yourself plenty of time, go outside and get ready. I always set a 30 second reminder on my watch or cell phone, so I don’t have to fumble around or guess the time.

To enjoy the NanoSail-D passes:

• Make sure you know the right place in the sky and the time of the pass, by checking on the web.
• Make sure you will be able to get a clear view of it from your viewing location.
• Set an alarm or get ready for the pass as it only lasts a few seconds.
• NASA expects NanoSail-D to stay in orbit through May 2011.
• If you are an astrophotographer, don’t forget, NASA and SpaceWeather.com are having an imaging contest of NanoSail-D. Find out more here.
• Most of all, get your friends and family outside with you to watch NanoSail-D and enjoy!
