CAPE CANAVERAL Fla. — The last space shuttle mission, STS-135, ended with the landing of the shuttle Atlantis at Kennedy Space Center’s Shuttle Landing Facility at 5:57 a.m. EDT. The air was thick with both humidity and mosquitoes. It was also a day thick with loss. The United States, for the foreseeable future, has lost the ability to launch massive payloads, such as the International Space Station’s Kibo module, into orbit. Lost the capabilities that a manned spacecraft with a robot manipulator system or RMS affords. Lost the ability to chase down wayward satellites, repair them on-orbit or return them to Earth for more intensive work. Lost, at least for the time being, its leadership position in terms of space flight – that position now belongs to Russia with its human-rated Soyuz Spacecraft and unmanned Progress Cargo vessels.

NASA is working to put a positive spin on this new era. The space agency hopes that small, commercial space firms will provide the nation with the capacity to send men and material to orbit as it works to travel beyond low-Earth-orbit (LEO) once again. Only time will tell how successful this direction will be, but there are positive signs that NASA might be on the right path. Following the space program for decades – you learn to hedge your bets. Today’s SpaceX is tomorrow’s Constellation Program.

Twin sonic booms shake me out of my revelry as the shuttle announces its return home. Then, a couple minutes later, there is the roar of the approaching orbiter. This sound comes not from shuttle, but rather from the sound of air being forcibly moved out of the shuttle’s path. I had set up two mini-camcorders to capture the landing, but had decided not to take any pictures. I took a moment, for myself, to watch as the shuttle roared past and landed.

There were a number of events held later in the day to commemorate the occasion. It struck me as odd that folks, some of whom would be in the unemployment line the following day, were celebrating. I decided to skip these events – I’ll celebrate when this nation regains the ability to launch astronauts into LEO. NASA Administrator Charlie Bolden worked to reassure everyone that all was well, given that he mistakenly said that the crew of STS-134 returned today – his words were not that reassuring.

With luck, when the U.S. does return to space again, it will do so on a multitude of different craft, with a multitude of different abilities – and hopefully launch vehicles. If these spacecraft are as different from one another as Boeing’s CST-100 is from Sierra Nevada Corporation’s Dream Chaser – that will be a very good thing – it will mean that many of the capabilities lost today will be replaced, albeit on completely separate vehicles.

That said, we are now entering an undiscovered country, one that NASA has never delved into before. Near the end of Apollo, the shuttle program was approved. With the end of the shuttle program here – NASA has no established human space flight program, it has initiatives, but no umbrella program, no clear path. That said, there are some potentially amazing things on the horizon – but they exist primarily on paper or on PowerPoint. Until they are fleshed out, until they fulfill their promises – today was a day of loss. Like the shuttle program, today was a mixed bag. One filled with hope for what might come, but uncertainty with what the future holds.

These are my personal reflections on the end of the shuttle program. They do not represent the opinions of Universe Today. These thoughts come from following and covering the space program for the last two decades and are not in favor of any one group’s position. I do not work to tell people things I think they want to hear – but what I feel they need to hear. I appreciate and welcome a mature debate with respect given by all sides for everyone’s point of view.

ULA Inks Deal With NASA To Study Man-Rating Atlas V

CAPE CANAVERAL Fla. — NASA is looking for a few good rockets – that’s right, plural. While it continues to review the Space Launch System or SLS – it has inked a non-funded agreement with United Launch Alliance (ULA) to utilize the Denver-based firm’s Atlas V rockets to send astronauts into orbit. The announcement was made at Kennedy Space Center in Florida on Monday.

The Space Act Agreement signed by the space agency and ULA will see critical information regarding the flight characteristics of the Atlas V be provided to NASA. ULA will not be alone in providing information however; NASA will give ULA vital data regarding its experience sending humans into orbit as well as guidance as how to adapt the Atlas V for human space flight purposes. NASA will help ULA with both the crew transportation system capabilities as well as the human certification requirements.

This will begin a process where ULA and NASA will work closely with one another to guide the Atlas V toward being man-rated. Before that can happen there are numerous pertinent issues that have to be reviewed first, such as the cost involved and other issues involved with the certification process.

The Atlas V is an expendable launch vehicle that has not only been used by NASA, but the Department of Defense (DoD) as well. The Atlas’ proven track record should allow a large portion of the study to be completed before the end of this year.

NASA’s part of the arrangement includes providing milestone briefings and technical reviews to check and see how the project is progressing as well as identifying risks and attempting to mitigate them.

ULA meanwhile will use its own funds to pay for the Crew Transportation System (CTS). Design maturation, required analyses (including hazard reviews that are unique to human space flight efforts) as well as establishing a man-rated baseline for the Atlas V all will be handled by United Launch Alliance.

The rationale behind why the Atlas V was specifically selected is simple, both Sierra Nevada Corporation and Blue Origin’s proposals under the Commercial Crew Development – 02 (CCDev-02) contract – utilize the Atlas V. Bigelow Aerospace has also looked at the rocket as a launch service provider.

“I am truly excited about the addition of ULA to NASA’s Commercial Crew development Program team,” said NASA Administrator Charles Bolden. “Having ULA on board may speed the development of a commercial crew transportation system for the International Space Station, allowing NASA to concentrate its resources on exploring beyond low
Earth orbit.”

The Atlas V has had 26 consecutive successful flights, making it an easily one of the front runners to potentially send astronauts to orbit.

“We believe this effort will demonstrate to NASA that our systems are fully compliant with NASA requirements for human spaceflight,” said George Sowers, ULA’s vice president of business development. “ULA looks forward to continued work with NASA to develop a U.S. commercial crew space transportation capability providing safe,
reliable, and cost effective access to and return from low Earth orbit and the International Space Station.”

One on One with SpaceX’s Garrett Reisman

[/caption]

CAPE CANAVERAL Fla. – Garrett Reisman knows a thing or two about what it takes to send astronauts to orbit. He should, he has taken the trip himself – twice. Reisman spent three months on the International Space Station launching with the STS-123 crew, and was a Mission Specialist on STS-132. He has walked in space, operated Canada’s Dextre robot and installed critical flight hardware to the ISS.

He has since left NASA to work for Space Exploration Technologies (SpaceX). Reisman took a moment to chat with Universe Today just before the final launch of the shuttle program, STS-135, on the orbiter Atlantis. Reisman spoke about SpaceX’s contract with NASA under the second phase of the Commercial Crew Development contract or CCDev-02, his new role as Director of SpaceX’s Dragon Rider program and whether there is another trip to space in his future.

Universe Today: Hi Garrett, thanks for taking the time to talk with us today, tell us a little about CCDev-02.

Reisman: “Thanks, it’s good to be here, SpaceX has dubbed CCDev-02 the ‘Dragon Rider’ program, CCDev sounds like someone’s logon name. Dragon Rider is the name of SpaceX’s efforts to send astronauts into orbit on board the Dragon Spacecraft.”

Universe Today: A nod to Anne McCaffrey’s Dragonriders of Pern?

Reisman: “Exactly!” (laughing)

Universe Today: If you had to pick out one of the most interesting elements of what SpaceX is working on for CCDev-02 – what would it be?

Reisman: “I think I would have to say it is the integrated launch abort system. The system that SpaceX is working on will not be the normal tower that is positioned above the spacecraft; instead it will be built into the sides of the Dragon. This system will be reusable and allow the Dragon to land.”

Universe Today: What do you think sets SpaceX apart from other, similar companies?

Reisman: “Some companies will offer you the rocket, others the spacecraft, at SpaceX we got both – it’s one-stop-shopping. We got the rocket, the Falcon 9, which has had two very successful test flights and we have the Dragon Spacecraft which became the first commercial spacecraft to orbit the Earth and splash down safely this past December. With both of these vital elements we have great confidence that we can do what we say we will do as we move forward.”

Universe Today: What made you decide to leave NASA and come to SpaceX?

Reisman: “I left NASA about four months ago and came over to SpaceX because I was very excited about what was going on in the commercial sector, just all this amazing innovation that was being unleashed and I wanted to be a part of that, to contribute to that.”

Universe Today: Final question, as a veteran astronaut are you hoping to ride Dragon to orbit one day?

Reisman: (smiles) While that’s not why I joined SpaceX – I wouldn’t rule it out either…”

SpaceX is looking to launch the next Falcon 9 rocket with Dragon Spacecraft some time this fall from Cape Canaveral Air Force Station’s Launch Complex 40. This demonstration flight will test out the Dragon’s navigation and other operating systems. This year SpaceX is planning to launch two flights under the Commercial Orbital Transportation Services or COTS contract, worth $1.6 billion, that the company has with NASA.

Return of the Capsule

CAPE CANAVERAL Fla. – As Florida’s Space Coast braces for the end of the shuttle program this month, signs of life after shuttle are starting to emerge. Space Exploration Technologies (SpaceX) returned the Dragon Spacecraft that launched this past December to Cape Canaveral Air Force Station. The Dragon however, was not alone. Two more capsules, one a test article, the other a mock-up were on display at Kennedy Space Center’s press site, signaling the coming way of the future for human spaceflight.

The Dragon Spacecraft was on display outside of Cape Canaveral Air Force Station. Placed between SpaceX’s Launch Control Center (LCC) and the U.S. Air Force Space and Missile History Center, the Dragon’s scorched hull was displayed to remind Space Coast residents that the space program was not retiring along with the shuttles.

“A lot of people are sad that the shuttle program is ending, it has been such an integral part of the area for three decades that they have a right to feel this way,” said SpaceX’s Vice President of Communications, Bobby Block. “Just because the shuttles are retiring however, does not mean that the entire space program is ending – it’s not over – it is the ending of one program, but it also is the start of another.”

That sentiment was shared by Lockheed Martin who brought their Orion Multi-Purpose Crew Vehicle to sit near the iconic Countdown Clock, a mere 3.5 miles away from shuttle Atlantis out at Launch Complex 39A. At first glance the fact that the capsule was still chained to the back of a trailer appeared to suggest that its appearance was rushed but in fact it highlighted a campaign by Lockheed Martin to let the public view Orion.

In conjunction with the final launch of the shuttle program, Lockheed-Martin had the Orion MPCV on display at the Kennedy Space Center press site. Photo Credit: Jason Rhian

“We were taking the Orion to Kennedy Space Center so we took the opportunity to stop along the way,” said Lockheed Martin’s Communications Manager for the Orion Project Linda Singleton. “This way we could tell the public about the Orion Program, let them see the spacecraft first hand. We stopped at Tucson, Austin and Tallahassee and met with 20,000 people in person across the country and talked to them about Orion.”

Not to be outdone, the Boeing Company had a replica of its CST-100 Space Taxi – split down the middle allowing guests to get an up close and in-depth look at the capsule-concept that it is submitting, in collaboration with Bigelow Aerospace, as their entry for NASA’s Commercial Crew Development (CCDev) program. If chosen, it would be used to ferry astronauts to the International Space Station. Boeing also had a structural article on display nearby.

“The reason we selected a capsule is that it is a simple system, we’ve been flown since John Glenn did his first flight on Mercury,” said Boeing’s Vice-President and Program Manager of Commercial Crew Programs John Elbon. “The purpose of this transportation system is just to take passengers to the space station, so our design is focused on that mission.”

The numerous capsules on display as well as other “Space-Taxi” systems such as the one proposed by Sierra Nevada highlight efforts to shrink the human space flight gap that will start on July 21, when Atlantis conducts its final wheel stop. With the number of spacecraft that have flown, are being tested or just now emerging off the drawing boards it is possible that the U.S. might have a variety of craft for a wide range of missions. For now however, NASA will have to rely on Russia’s Soyuz Spacecraft.

XCOR Lynx Slated to Fly New Suborbital Telescope

Commercial space company XCOR Aerospace has signed a “Memorandum of Understanding” with the Planetary Science Institute, laying the groundwork for flying a human-operated telescope on board XCOR’s Lynx spacecraft. The Atsa Suborbital Observatory is a specially designed telescope for use in suborbital space vehicles, and when used with commercial suborbital vehicles, PSI says it will provide low-cost space-based observations above the contaminating atmosphere of Earth, while avoiding some operational constraints of satellite telescope systems.

“The XCOR vehicle design and capabilities work well for hosting the kind of observing facility we are developing,” said PSI Senior Scientist Faith Vilas, the Atsa Project Scientist.

“NASA has been flying suborbital observatories for decades, on unmanned, disposable rockets. The new manned, reusable commercial platforms will allow us to make repeated observations with a single instrument, but without the need to refurbish it between flights,” said Luke Sollitt, and affiliate scientist with PSI and a co-inventor with Vilas of the Atsa Observatory. “In addition, the short turn-around means we can do many observations or targets.”

Atsa means “eagle” in the Navajo language. The facility is optimized for observing solar system objects near the sun that are difficult to study from orbital observatories such as Hubble and ground-based telescopes.

The Lynx is a two-seat, piloted space transport vehicle, capable of taking humans and payloads on a half-hour suborbital flight to 100 km (330,000 feet) and then return safely to a landing at the takeoff runway, providing 4-6 minutes of weightless flight.

Like an aircraft, Lynx is a horizontal takeoff and horizontal landing vehicle, but instead of a jet or piston engine, Lynx uses its own fully reusable rocket propulsion system to depart a runway and return safely.

The Atsa Observatory will be mounted on the top of the Lynx in an experiment pod. XCOR or PSI did not release the cost per flight, but XCOR’s price for one passenger is $95,000 USD. In contrast, the price for using sounding rockets vary, depending on how high the rocket goes, but some cost as little as $10,000 USD.

“These are natural targets for instruments on suborbital rockets to observe, but a human-tended facility using the kind of reusable launch vehicle offered by XCOR offers significant cost savings,” said Mark Sykes, CEO and Director of PSI, who is also a long-time planetary astronomer and is training to be an Atsa operator.

The Lynx spacecraft will fly to space on a customized flight trajectory and will be capable of precision pointing, allowing the Atsa system with its operator to acquire the desired target and make the planned observations. “We are being approached by many potential customers who are interested in supporting observations of the inner solar system,” Vilas said. “We will also be able to support target of opportunity observations for newly discovered objects and other phenomena.”

“We’re looking forward to flying PSI’s Atsa system on Lynx, it will be a groundbreaking experience. The rapid and flexible operations of the Lynx will enable scientists to pick specific targets of interest and the same day fly multiple tailor made observation missions quickly and inexpensively when they want them to be flown,” said Khaki Rodway McKee, XCOR’s Program Manager.

“We are entering into a new era in the human exploration of space, where private companies like XCOR and PSI will begin to play leading roles in certain areas, beginning with suborbital flight – harkening back to the days of NASA’s Mercury program,” Sykes said.

Andrew Nelson, XCOR’s Chief Operating Officer, said, “Much like the early days of the Internet, mobile communications and social networking revolutions saw new and innovative applications drive commercial multi-billion dollar marketplaces, so we are seeing privately funded efforts like PSI’s Atsa as a key early adopter signaling a robust future for suborbital reusable launch vehicles.”

SpaceX Seeking Tweets From The Final Frontier

[/caption]

Space Exploration Technologies — or SpaceX as they are more commonly known — has gotten pretty good at launching rockets. Now they want the rest of the world to follow along – one Tweet at a time. The social media site Twitter allows users to post brief comments (under 140 characters). SpaceX views this as a means to keep the public informed about the company’s activities including the upcoming launch of the firm’s Falcon 9 rocket.

SpaceX can be found under the name of @SpaceXer. The NewSpace firm will post regular updates about the company’s activities on Twitter. SpaceX has been working to increase its public and media relations efforts lately. The push for more viewers on Twitter is part of these efforts.

“There are a lot of amazing things that are taking place at a daily basis at SpaceX,” said SpaceX’s Vice President of Communications Bobby Block. “We want to invite the public, everyone really, to follow these events on our Twitter account.”

SpaceX currently plans to launch the next of its Falcon 9 rockets this September. It will be another mission to prove out the Falcon 9’s readiness to begin cargo flights to the space station. For this mission, a flyby of the International Space Station is planned to test out communications equipment. The Dragon spacecraft will then reenter Earth’s atmosphere and splash down in the Pacific Ocean.

This will be the third time that SpaceX has launched a Falcon 9 from Space Launch Complex 40 at Cape Canaveral Air Force Station (CCAFS) in Florida. This past December SpaceX became the first private company to launch a spacecraft to orbit and retrieve it safely from the Pacific Ocean. It is accomplishments such as this that SpaceX wants to broadcast to the world.

“SpaceX has successfully demonstrated not only the viability of the Falcon 9 as a launch vehicle – but also the capabilities of the Dragon Spacecraft,” Block said. “This is just the beginning, now we want the world to come ride along with us.”

SpaceX was selected for not only the Commercial Orbital Transportation Services (COTS) contract with NASA – which has a $1.6 billion value but for NASA’s Commercial Crew Development 2 (CCDev-02) contract as well. Add to that the many business deals that SpaceX has made to send payloads into orbit – and SpaceX has a lot to tweet about.

SpaceX and founder Elon Musk have made it public knowledge regarding their plans to one day launch astronauts to the International Space Station, build a far larger version of its Falcon 9 dubbed the “Falcon Heavy” and to reach out to the planet Mars. SpaceX thinks with plans such as these in the works, space fans and novices alike will be very interested in following along.

Of course, SpaceX is not the only space organization that has recognized the value of social media like Twitter. NASA has embraced Twitter, with almost all of the missions and spacecrafts having Twitter accounts, and fans are finding Twitter to be a great way to find out the latest details from space. Additionally, NASA regularly hosts “Tweetups” when large events are scheduled to take place, such as the upcoming final launch of the space shuttle program.

Burt Rutan’s Race To Space: A Primer For Things To Come

Dan Linehan's recent offering entitled "Burt Rutan's Race to Space" is a concise, yet detailed, accounting of how one man revolutionized air and space travel. Photo Credit: Zenith Press

[/caption]

Voyager, Proteus and SpaceShipOne have become aerospace legends. As has the man who established them all – Burt Rutan. Zenith Press has released a chronicle of the man and his machines entitled Burt Rutan’s Race to Space: The Magician of Mojave and His Flying Innovations. The book provides a chronicle of all the air and spacecraft that have soared off of Rutan’s blueprints and into reality.

The book’s first main segment is a large section which is essentially a catalog of the numerous craft that Rutan has produced over the decades. Many of the flying machines have their unique characteristics highlighted within the 160 pages of this book. Fear not, this tome is wallpapered with images – most of which are color (175 color images to 55 black and white).

Some of the most interesting of these images are not the glossy stills of air or spacecraft in action but rather the simple drawings that are done by the man himself. These sketches, some little more than cartoons others just simplistic line-drawings, highlight the genius that is Rutan and provide an insight into how his mind works.

The nature of the book changes somewhat when one reaches the chapter entitled, “The Scaled Composites Years.” From this point on, the book’s focus narrows to concentrate on Rutan’s X-PRIZE efforts – and beyond.

The book was written by Dan Linehan and is his second detailing the efforts of Rutan and Scaled Composites (the first was SpaceShipOne: An Illustrated History). In short, the freelance writer is steeped in all things Rutan. Whereas his first work on the subject covered the history-making flight of SpaceShipOne, this effort is a general overview of Rutan and his legacy. But be forewarned, there are many projects that span the entire realm of aerospace that Rutan and company have been involved with that might surprise you.

Given that the Mojave “magician” has retired recently – this book is timely, enjoyable and acts as a wonderful window into the mind of the man that has revolutionized flight. SpaceShipTwo continues to successfully complete test after test – making Burt Rutan’s Race to Space a primer for things to come. The book retails for $30, and it is well-worth the price and will be a welcome addition to any space buff’s collection.

Copenhagen Suborbitals hopes to launch the world’s first amateur-built rocket for human space travel and have announced an upcoming launch window for their Tycho Brahe capsule. The window extends from June 1-14, 2011 and they are currently shooting for Thursday, June 2 for an unmanned suborbital test flight, according the their website. The group is headed by Kristian von Bengtson and Peter Madsen, and their HEAT 1-X rocket is being prepared for launch from a steel catamaran in the Baltic Sea off the coast of Denmark.

If all goes well with this test flight, Madsen hopes to be inside the capsule himself for a manned flight in the near future.

The company, which is funded by donations, is working towards launching tourists on suborbital flights in the single-seat capsule to altitudes above 100 kilometers (62.5 miles).

And talk about a wild ride : the Tycho Brahe capsule will provide a single passenger capsule with a full view through a polymer plexiglas-dome so that the person can see and experience the entire ballistic ride. It has a pressurized volume providing support for one upright standing/half-sitting person. It will also have additional pressurized space, around and behind the astronaut, available for several other systems necessary for the flight procedure, and to support additional scientific and commercial project.

Copenhagen Suborbitals were hoping to launch their first test flight last summer, but ran into problems with their rocket.

UK and European Space Agencies Give a Go For Skylon Spaceplane

After 30 years of development, the UK and European space agencies have given a go for the Skylon Spaceplane.

The Skylon, which is being developed at the Oxfordshire-based Reaction Engines in the UK, is an unpiloted and reusable spacecraft that can launch into Low Earth Orbit after taking off from a conventional runway.

Looking like something out of Star Wars, Skylon is a self contained, single stage, all in one reusable space vehicle. There are no expensive booster rockets, external fuel tanks or huge launch facilities needed.

The vehicle’s hybrid SABRE engines use liquid hydrogen combined with oxygen from the atmosphere at altitudes up to 26km and speeds of up to Mach 5, before switching over to on-board fuel for the final rocket powered stage of ascent into low Earth orbit.

The Skylon is intended to cut the costs involved with commercial activity in space, delivering payloads of up to 15 tons including satellites, equipment and even people into orbit at costs much lower than those that use expensive conventional rockets.

Once the spacecraft has completed its mission, it will re-enter Earth’s atmosphere and return to base, landing like an airplane on the same runway, making it a totally re-usable spaceplane, with a fast mission turn around.

Skylon has received approval from a European Space Authority panel tasked with evaluating the design. “No impediments or critical items have been identified for either the Skylon vehicle or the SABRE engine that are a block to further development,” the panel’s report concludes.

“The consensus for the way forward is to proceed with the innovative development of the engine which in turn will enable the overall vehicle development.”

The UK Space Agency says that Reaction Engines will carry out an important demonstration of the SABRE engine’s key pre-cooler technology later this summer.

Watch SpaceShipTwo’s First Feathered Flight

On May 4, 2011 Virgin Galactic’s SpaceShipTwo achieved a major milestone by flying for the first time using its “feathered” configuration, and the company has now released a close-up video of the flight. Feathering is designed to create drag and slow the ship down after it reenters the atmosphere from eventual suborbital flights taking tourists into space. This flight confirmed the feathering design should work.

“Now we now have an entry vehicle – now we can come back from space,” said Matt Stiemetze, Program Manager at Scaled Composites
