CAPE CANAVERAL – Much has been made about the secretive nature of the Orbital Test Vehicle (OTV). Better known as the X-37B, the second of the U.S. Air Force’s OTVs roared off Cape Canaveral Air Force Station’s Launch Complex 41 at 5: 46 p.m. EDT. The Atlas V 501 thundered off of the launch pad carrying the second of the two OTVs into orbit.

The launch was to take place on Mar. 4, but looming cumulus clouds, high winds and rain pushed the launch back a day. The first launch window today opened at 4:09 p.m. EDT, however technical issues required minor work out on the launch pad and it was decided to try for launch during the second launch window’s opening.

The first OTV, USA-212 lifted off from the exact same launch pad on 22 April 2010 and returned to Earth on Dec. 3, 2010. The return to earth tested out the space planes heat shield as well as the vehicle’s hypersonic aerodynamic aspects. The space plane is small enough to be carried within the U.S. space shuttle’s payload bay, it landed at Vandenberg Air Force Base in California. The craft suffered a tire blowout upon landing, but landed safely.

“The X-37B is a scientific achievement as well as a tremendous step in space operations. By itself, the ability to put a vehicle in space, conduct experiments and tests for close to nine months and then have that vehicle autonomously de-orbit and land is an important accomplishment,” said Major Tracy Bunko an Air Force spokeswoman. “This gives the Air Force the ability to examine how state-of-the-art, highly complex technologies will perform in space before they are made operational is an important cost-saving, risk-reducing capability.”

U.S. Air Force officials stated that the X-37B program has the potential of making space experiments much more affordable. This would allow future experiment designers to focus their resources and funds on technology and innovation rather than on what they currently are forced to expend them on – basic services, redundancy and ground operations.

CAPE CANAVERAL – Weather delayed the launch of the second of the United States Air Force’s Orbital Test Vehicles (OTV). The X-37B, as it is more commonly known, sate encapsulated within its fairing on top of the Atlas V 501 launch vehicle at Cape Canaveral Air Force Station (CCAFS).

It appeared that the launch might occur at the first launch window, which opened at 3:50 p.m. EDT. However high-level ground winds forced a delay. The second launch window was for 5:27 p.m. EDT, but by this time the winds had increased, Cumulous Clouds had moved into the area – bringing heavy rains in with them, forcing a scrub for the day. The plans are now for a 24-hour recycle of the launch, however tomorrow does not look much better with similar weather threatening the launch.

The second X-37B Orbital Test Vehicle (OTV-2) built for the US Air Force was rolled out today (March 3) to the Atlas rocket launch pad at Space Launch Complex-41(SLC-41) at Cape Canaveral Air Force Station, Florida.

The experimental OTV-2 is poised to blast off on Friday, March 4 on an Atlas V rocket in a launch window that extends from 3:39 pm to 5:39 p.m. EST. The X-37B is encapsulated in a 5 meter fairing.

The secret cargo and experiments loaded aboard are shrouded behind a veil of military security.

UPDATE: Due to weather concerns, the launch has been postponed until Saturday, March 5. Weather is predicted to improve to 40% favorable for launch.

Air Force technicians are completing final preparations for the late afternoon blast off of the bronze colored rocket topped by the extra long payload fairing to accommodate the OTV-2.

The rocket is sitting atop the mobile launch platform and was pushed about 1800 feet from the 31 story Vertical Integration Facility (VIF) to launch pad 41 by twin diesel powered trackmobiles. See my photo album of today’s X-37B rollout and close up visit to the Atlas rocket at SLC-41.

“No major changes were required from the OTV-1 flight based on post-flight assessments, but we did make a few minor modifications based on lessons learned from the first flight,” Tracy Bunko, Maj, USAF of the Air Force Press Desk told me in an interview.

“We’re pleased with what we’ve seen so far. Technology assessments are ongoing in areas including re-entry guidance, navigation, and control, thermal protection systems, and flight actuation systems.”

“We want to potentially test the landing capabilities in stronger wind conditions,” Bunko explained.

CAPE CANAVERAL – In preparation for the launch of the second of the U.S. Air Force’s Orbital Test Vehicles (OTV), the Air Force has released images of the OTV being encapsulated within the fairing that goes on top of the Atlas V AV-026 launch vehicle. Currently, the launch is scheduled to take place on Friday, March 4. The launch window is between 3:39 p.m. EDT and 5:39 p.m. EDT.

UPDATE: Due to weather concerns, the launch has been postponed until Saturday, March 5. Weather is predicted to improve to 40% favorable for launch.

The tiny X-37B space plane is better known as the X-37B. The small spacecraft was designed to fit within the payload bay of the space shuttle. It currently is inside the Atlas’ 5-meter fairing. This is what is known as the X-37B Orbital Test Vehicle encapsulated assembly or EA. The EA being hoisted to the top of the rocket is one of the last major assembly endeavors before launch.

How Does the Shuttle Orbiter Get Attached to the External Tank and Solid Rocket Boosters?

Ever wondered how the space shuttle orbiter gets attached to the big external tank and the solid rocket boosters? This video shows the process — called “Lift and Mate” — where the shuttle Endeavour was put into a special harness, lifted high above the stacked ET and SRBs inside the Vehicle Assembly Building at Kennedy Space Center, and lowered into place. The orbiter is then bolted to the ET and SRBs. Endeavour’s Lift and Mate for its final flight took place on March 1, 2011. You can also see extremely high resolution, pan and zoom images of Endeavour lifted high in the VAB at the NASATech website. (High bandwidth warning! — but definitely worth it.) See the NASATech main page for the full variety of images.

Endeavour is scheduled to rollout to Launch Pad 39A next week for STS-134, with launch set for April 19. Even though this could be the final flight of the shuttle program (STS-135 is still not a certainty) many people are looking forward to this flight, as it will bring the Alpha Magnetic Spectrometer to the ISS. AMS is a particle physics detector designed to search for various types of unusual matter by measuring cosmic rays.

NASAs Navy tows Discoverys Last Rocket Boosters into Port Canaveral – Photo Album

As the Space Shuttle program quickly winds down, one of the lesser known facts is that the public can get a free bird’s eye view of the ocean retrieval of the mighty Solid Rocket Boosters which power the orbiters majestic climb to space. All you have to do is stand along the canal of Port Canaveral, Florida as the rockets float by on their journey to a processing hanger at Cape Canaveral Air Force Station.

And if you own a boat you can sail right along side for the thrilling ride as the boosters are towed by ship from the Atlantic Ocean into the entrance of Port Canaveral. It’s the same route traveled by the humongous cruise ships setting sail for distant ports on Earth.

NASA’s Navy has recovered the twin Solid Rocket Boosters (SRB’s) used during space shuttle Discovery’s final flight. See my photo album above and below.

The two SRB’s and associated flight hardware are retrieved after they splashdown in the Atlantic Ocean following every shuttle launch by the NASA owed ships named Freedom Star and Liberty Star.

Freedom Star and Liberty Star are stationed about 10 miles from the impact area at the time of splashdown. The ships then sail to the SRB splashdown point and divers are deployed to attach tow lines, haul in the parachutes used to slow the descent and install dewatering equipment.

Each vessel tows one SRB all the way from the Atlantic Ocean into Port Canaveral and then through the locks to Cape Canaveral Air Force Station. After the spent segments are decontaminated and cleaned, they will be transported to Utah, where they will be refurbished and stored, if needed.

The unique ships were specifically designed and constructed to recover the SRB’s. The SRB’s separate from the orbiter about two minutes after liftoff. They impact in the Atlantic about seven minutes after liftoff and some 100 nautical miles downrange from the launch pad off the Florida coastline.

The STS-133 mission was launched from pad 39A at NASA’s Kennedy Space Center on Feb. 24 on Discovery’s 39th and last space flight. Landing is slated for March 8 at 11:36 a.m. at KSC.

The all veteran six person crew has successfully attached the Leonardo storage module and completed two space walks. Leonardo is packed with the R2 humanoid robot and tons of science gear, spare parts, food and water.

No-go for ‘Fly About’ Photo-Op at Space Station

The international partners have decided against an historic ‘fly-about’ of the International Space Station, which would have provided one-of-a-kind images of the nearly completed ISS with space shuttle Discovery and an assortment of vehicles from the different participating space agencies docked to the station.

“This morning, our Russian colleagues, after doing their own independent review processes … have determined that they are not in position to recommend doing the fly about, because this particular vehicle is what they consider a new vehicle, the Series 700 vehicle, which is in its maiden flight,” said Kenneth Todd, a manager for Mission Integration and Operations at NASA, speaking at a mission briefing this morning.

The Russians felt they didn’t have the time or opportunity to fully understand, review and work through all the risks of the request of flying the Soyuz around the ISS, an idea which was presented only recently, and after the new Soyuz had already launched to orbit.

“From a MMT perspective, we knew it was critical for all partners to go through their processes,” Todd said. “It wasn’t necessarily what we were hoping to get back, but at the same point I applaud the Russians for doing the right thing, for not disregarding their own processes and making sure they do their own due diligence the way they should. I accepted the recommendation.”

Mission Control in Houston radioed up to ISS commander Scott Kelly and STS-133 Commander Steve Lindsey that the possible Soyuz fly about was a no-go, even though mission managers had already approved an extra day extension of the shuttle mission.

“We’ll now use that extra day for transfer work between the PMM (Permanent Multipurpose Module) and the ISS, to leave the station and crew in the best possible shape when Discovery undocks.” said Capcom Stan Love. “The fly about will not happen during this flight.”

The fly-about –- only proposed about two weeks ago — would have had cosmonauts Alexander Kaleri and Oleg Skripochka along with Kelly to undock from the Russian Poisk module in the Soyuz TMA-01M spacecraft, back away from the ISS so they could show the ISS in its nearly completed configuration, with the shuttle attached, along with the Russian Progress and Soyuz, the European ATV and the Japanese HTV-1.
Todd said the images would not only be historic from an aesthetic perspective, but also provide valuable engineering views and data.

“There are multiple reasons this was going to be a good thing, to do this photo documentation,” he said. “Everytime we do one of these things we learn a lot, and we get a lot of good data about our ability to do this type of function, not just on our side but on the Russian side. I don’t see our review of this as wasted time or effort, and if we ever need to do this in the future, we will have to assess that at the time.”

Todd added that they should be able to get most of the images and data they were hoping for when the shuttle undocks and departs from the ISS next week – save for the historic aspect of having a shuttle docked to the station, along with all the other visiting vehicles.

Earlier today, the crews of STS-133 and the space station successfully installed the Leonardo Permanent Multipurpose Module, essentially storage space (a “float-in” closet – which has also been referred to as a potential Man-cave) which includes supplies. Also tucked inside is Robonaut-2, the first human-like robot to serve on board the space station.

Discovery’s landing is currently set for 11:36 am EST on Tuesday, March 8, 2011.

Endeavour Rolls to Vehicle Assembly Building for Final Flight

[/caption]NASA’s Space Shuttle Program is inexorably and swiftly headed towards its finale.

With shuttle Discovery orbiting some 200 miles overhead on her final flight, launch preparations for the final flight of Space Shuttle Endeavour moved into high gear.

Endeavour was rolled a few hundred yards from her processing hanger at the Kennedy Space Center to the Vehicle Assembly Building (VAB) where she will be attached to the external fuel tank (ET) and twin solid rocket boosters (SRB) which will power her final trip to space. See photo album below from Alan Walters and Ken Kremer.

NASA plans to transport Endeavour to Launch Pad 39 A on March 9 for the STS-134 missionand her 25th and final flight. Launch is set for April 19.

Endeavour and her six person crew will deliver the Alpha Magnetic Spectrometer, a $1.5 Billion particle physics detector designed to search for dark matter and determine the origin of the Universe. The crew will also deliver a platform that carries spare parts platform parts that will sustain station operations once the shuttles are retired later this year.

The quarter mile trip on a 76 wheeled transporter began about 7 AM this morning (Feb 28). The orbiter was backed tail first out of the processing hanger known as the Orbiter Processing Facility and then ‘rolled over’ to the VAB and parked close to the entrance doors.

Rollover marks the start of the final phase of launch preparations for the STS-134 mission. Hundreds of Shuttle workers who process the orbiters for flight were invited to witness the event and pose for photo ops with the spaceship. Most KSC employees never get the chance to glimpse the orbiters up close.

The next major milestone is for Endeavour to be hoisted and mated to the External Tank on Tuesday and prepare for rollout to the launch pad.

I thought I had a great view of space shuttle Discovery’s final launch, seeing it from the Kennedy Space Center press site. But there were a few other people who had a pretty unique perspective on the launch. A passenger on an airplane, Neil Monday, who was flying out of the Orlando, Florida airport, recorded the shuttle launch with his iPhone, above. That is just awesome. Want more unique views of the launch?

The students from Quest For Stars who were attempting to capture an image of Discovery’s launch from a high altitude balloon (see our preview article) were successful and the team has released a couple of images, including the one above. They say they will be releasing the “best of the best” of their images later this week at the Next Generation Suborbital Research conference. They have a great video of their balloon popping, sending their payload into a quick freefall.

Speaking of freefall, former astronaut Fred Leslie and his wife Kathy wanted to do something special to commemorate Discovery’s final launch. They jumped from an aircraft over Deland, Fla., and timed it so they could get a photograph with Discovery taking off in the background. Read more about it in the Huntsville Times.

And of course, if you want to see more launch images, we have a great gallery of the STS-133 launch as seen by our cadre of reporters and photographers who were on hand for Discovery’s historic launch.
