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.

Air Force and ULA to launch second X-37B

CAPE CANAVERAL – From all appearances the first flight of the U.S. Air Force’s secretive X-37B space plane was a complete success. As such, the Air Force is planning to launch a second Orbital Test Vehicle (OTV) on March 4 from Cape Canaveral Air Force Station in Florida on top of a United Launch Alliance (ULA) Atlas rocket. The Air Force has not yet released a specific launch time.

The first flight of an OTV took place on Apr. 22, 2010 on top of an Atlas V 501 rocket and was designated USA-212. Built by Boeing, the spacecraft is unmanned and is in many ways similar to the space shuttle. It has a payload bay, maneuvering thrusters up front and to the rear of the spacecraft and a single, primary engine.

The OTV is different from the space shuttle in that it can operate on-orbit for up to 270 days. During the vehicle’s maiden flight it was spotted by a number of amateur astronomers who verified that the craft changed orbits a number of times before it landed safely at Vandenberg Air Force base on Dec. 3, 2010.

“We are tremendously excited to launch the second OTV space vehicle for the Air Force Rapid Capabilities Office. Our combined Air Force and ULA mission partner team has worked hard to prepare the Atlas V for this mission which is the first launch of the year for ULA from the east coast in 2011,” said ULA’s Director of Communications, Mike Rein. “I fully expect this launch to be a 100 percent successful mission – just like the first OTV launch in April 2010.”

Originally the OTV was to be deployed from the space shuttle’s payload bay, after the Columbia accident however, it was decided to launch from an EELV instead. At first a Delta II was given the nod to launch the space plane – before the Atlas V was confirmed as the launch vehicle that would be used.

The U.S. Air Force has disclosed only minimal information regarding the first mission and has said little about the upcoming mission as well. The Air Force has stated that the length of the OTV’s mission’s will be determined by the completion rates of the experiments that are onboard. Mission control is based out of Colorado with the 3d Space Experimentation Squadron.

The X-37B is only the second reusable spacecraft that is capable of conducting an automated landing. The only other reusable craft that has demonstrated this capability was Russia’s Buran shuttle which returned safely to Earth on Nov. 15, 1988.

The X-37B was a program initially handled by NASA; however the program was eventually turned over to the U.S. Defense Advanced Research Projects Agency (DARPA) and the Pentagon. The OTV flew several times on Scaled Composites’ White Knight aircraft and was drop tested twice successfully in 2006.

Can China enter the international space family?

China has become only the third nation in the world to have a manned space program. Photo: Chine

It has often been called a ‘100 billion boondoggle’ – yet it is also unquestionably one of the most successful international programs in human history. The International Space Station (ISS) is just now starting to produce some of the valuable science that was the station’s selling point from the beginning. However, this delay can be attributed to the numerous tragedies, economic woes and other issues that have arisen on a global scale through the course of the station’s construction.

The one thing that the world learned early on from the ISS experience is that space is a great forum for diplomacy. One time arch-rivals now work side by side on a daily basis.

With much of the nations of the world talking about stepped-up manned exploration efforts it would seem only natural that the successful model used on the space station be incorporated into the highly-expensive business of manned space exploration. If so, then one crucial player is being given a hard look to see if they should be included – China.

“International partnership in space exploration has proven its worth over the last decade. It would be a positive step if the other space-faring nation of the world, China, were to join the assembled space explorers of humankind as we march outward into the solar system,” said former NASA Space Shuttle Program Manager Wayne Hale who writes a popular blog about space matters.

China is only the third nation (behind Russia and the United States) to have a successful manned space program, having launched its first successful manned space flight in 2003. This first mission only had a single person onboard, and gave the world a new word – ‘taikonaut’ (taikong is the Chinese word for space). The country’s next mission contained two of these taikonauts and took place in 2005. The third and most current manned mission that China has launched was launched in 2008 and held a crew of three.

China has steadily, but surely, built and tested capabilities essential for a robust manned space program. Considering that China very ambitious goals for space this would seem a prudent course of action. China has stated publically that they want to launch a space station and send their taikonauts to the moon – neither of which are small feats.

China currently utilizes its Shenzhou spacecraft atop the Long March 2F booster from their Jiuquan facility. However, if China wants to accomplish these goals, they will need a more powerful booster. This has been part of the reason that the U.S. has been hesitant to include China due to concerns about the use of what are known as dual-use technologies (rockets that can launch astronauts can also launch nuclear weapons).

Some have raised concerns about the nation’s human rights track record. It should be noted however that Russia had similar issues before being included in the International Space Station program.

“In the early 1990’s, some at NASA thought having Russian cosmonauts on the Space Shuttle would mean giving away trade secrets to the competition,” said Pat Duggins, author of the book Trailblazing Mars. “It turned out Russian crew capsules saved the International Space Station when the Shuttles were grounded after the Columbia accident in 2003. So, never say never on China, I guess.”

Duggins is not the only space expert who feels that China would make a good companion when mankind once again ventures out past low-Earth-orbit.

“One of the findings of the Augustine Commission was that the international framework that came out of the ISS program is one of the most important. It should be used and expanded upon for use in international beyond-LEO human space exploration,” said Dr. Leroy Chiao a veteran of four launches and a member of the second Augustine Commission. “My personal belief is that countries like China, which is only the third nation able to launch astronauts, should be included. My hope is that the politics will align soon, to allow such collaboration, using the experience that the US has gained in working with Russia to bring it about.”

Not everyone is completely convinced that China will be as valuable an asset as the Russians have proven themselves to be however.

“It is an interesting scenario with respect to the Chinese participation in an international effort in space. The U.S. has made some tremendous strides in terms of historical efforts to bridge the gap with the Russians and the results have been superb,” said Robert Springer a two-time space shuttle veteran. “The work that has resulted in the successful completion of the International Space Station is an outstanding testimony to what can be done when political differences are set aside in the interest of International cooperation. So, there is a good model of how to proceed, driven somewhat by economic realities as well as politics. I am not convinced that the economic and political scenario bodes well for similar results with the Chinese. It is a worthwhile goal to pursue, but I am personally not convinced that a similar outcome will be the result, at least not in the current environment.”

China's journey into space has just begun, but it remains to be seen if they will be going it alone or as part of a partnership. Photo Credit: Xinhua

Navy Railgun Sets a New Record

*Gulp* If you haven’t seen this video yet, its worth a look. On December 10, 2010, the Office of Naval Research Electromagnetic Railgun fired a world-record setting 33 megajoule shot, breaking the previous record of 32 MJ. Railguns accelerate a conductive projectile along a pair of metal rails, and are being researched as weapons. The projectiles do not contain explosives, but with extremely high velocities can do quite a bit of damage. “Velocitas Eradico” indeed. (Speed destroys). Of course the other potential use for a railgun would be to launch payloads off Earth or the Moon. Make sure you watch the high-speed portion of the camera following the projectile along its flight. And you might flinch (I know I did!) in the portion where the projectile basically comes right at you.

The secret military space plane has returned home, and while the mission was classified, the Air Force and Boeing have supplied pictures of the craft after landing. With this mission appearing to be a success, the Air Force is preparing to launch the next X-37B, OTV-2, in Spring 2011 aboard an Atlas V booster.

See more images below.

The X-37B mini space shuttle made a stealth landing during the early morning hours, landing at Vandenberg Air Force base at 1:16 a.m. PDT (0916 GMT) today (Friday, Dec. 3.) The US Air Force’s first unmanned space plane successfully glided to a landing after nearly 225 days in space.

X-37B program manager Lt Col Troy Giese stated moments after landing, “We are very pleased that the program completed all the on-orbit objectives for the first mission.”

Above is an infrared camera view of the space plane taxiing after landing this morning.

The space plane’s exact mission was not divulged, and the Air Force did not immediately report anything about the performance of the spacecraft or if any issues arose.

The X-37B’s mission is to “demonstrate a reliable, reusable, unmanned space test platform for the United States Air Force,” according to a fact sheet put out by the military. “Objectives of the OTV program include space experimentation, risk reduction and concept of operations development for reusable space vehicle technologies.”

Secret Mini Space Shuttle Could Land on Friday

The US Air Force announced that the X-37B Orbital Test Vehicle, a miniature, unmanned space shuttle could return to Earth as soon as this Friday, December 3. It has been in Earth orbit for about nine months on a classified mission for the military. It will land at Vandenberg Air Force Base in Los Angeles sometime between Friday and Monday, Air Force officials said in a statement. The exact time of touchdown will depend on weather conditions and technical factors.

Preparations for the landing began on Tuesday, the Air Force Space Command said. The backup landing site would be Edwards Air Force Base.

The X-37B launched from Cape Canaveral, Florida on April 22. It was built by Boeing, and the vehicle looks like a space shuttle orbiter, but is much smaller: at 9 meters long and 4.5 meter wide (29 X 15 ft), with a payload bay that is 2.1 by 1.2 meters (7 by 4 feet) the X-37B is about 1/4th the size of a shuttle.

The X-37B uses solar arrays and lithium ion batteries to generate power instead of fuel cells like the space shuttle, a major reason why it can stay on orbit for much longer.

Originally the vehicle was scheduled for launch in from the payload bay of the Space Shuttle, but that plan was axed following the Columbia accident.

The X-37B’s mission is to “demonstrate a reliable, reusable, unmanned space test platform for the United States Air Force,” according to a fact sheet put out by the military. “Objectives of the OTV program include space experimentation, risk reduction and concept of operations development for reusable space vehicle technologies.”

It will be interesting to see if the military will share any of the on-orbit activities of the space plane and what capabilities and uses this vehicle might have in the future.
