SpaceX successfully completed a key test of the Falcon 9 rocket that will fly the first commercial flight to the International Space Station. Called a ‘wet dress rehearsal,’ SpaceX brought the Falcon 9 “stack” with the Dragon capsule atop to the launch pad at Cape Canaveral on March 1, and loaded it with 76,000 gallons of highly refined kerosene and liquid oxygen fuel. Pre-liftoff operations were conducted as engineers went through a full count-down simulation, stopping at 5 seconds before ‘launch.’

SpaceX said the test was a success and was an important step on the road to the Space Station. “The test went well,” said SpaceX spokeswoman Kirstin Grantham. “Over the coming days, we will continue to review the data as we prepare for our upcoming mission.”

The launch of this historic flight will likely be April 20, or later, depending on the results of this and other tests.

After the wet dress rehearsal, the fuel was drained, and the rocket was later rolled off the launch pad on March 2, and the SpaceX said Dragon will be taken off for additional testing.

Additionally, on March 2, SpaceX conducted another test, called a 9-engine test, firing the engines for a future Falcon 9 rocket. This took place near McGregor, Texas.

As the “real” launch date approaches for the current rocket, the Falcon 9 will again be brought to the Launchpad to fire the nine first-stage engines and practice late packing of cargo in the Dragon.

“These rehearsals allow SpaceX to test out both the vehicle and the ground systems before launch,” Grantham said.

SpaceX is working towards becoming the first commercial spacecraft to dock with the ISS under NASA’s commercial orbital transportation services (COTS) commercial crew development (CCDev) programs. Later this year, another COTS company, Orbital Sciences hopes to launch their Antares rocket and Cygnus capsule from Wallops Island, Virginia.

SpaceX Test Fires SuperDraco Abort Engines Critical To Astronaut Launch Safety

Space Exploration Technologies (SpaceX) has test fired a prototype of its new SuperDraco engine that will be critical to saving the lives of astronauts flying aboard a manned Dragon spacecraft soaring to orbit in the event of an in-flight emergency.

The successful full-duration, full-thrust firing of the new SuperDraco engine prototype was completed at the company’s Rocket Development Facility in McGregor, Texas. The SuperDraco is a key component of the launch abort system of the Dragon spacecraft that must fire in a split second to insure crew safety during launch and the entire ascent to orbit.

The Dragon spacecraft is SpaceX’s entry into NASA’s commercial crew development program – known as CCDEV2 – that seeks to develop a commercial ‘space taxi’ to launch human crews to low Earth orbit and the International Space Station (ISS).

The engine fired for 5 seconds during the test, which is the same length of time the engines need to burn during an actual emergency abort to safely thrust the astronauts away.

Watch the SpaceX SuperDraco Engine Test Video:

Nine months ago NASA awarded $75 million to SpaceX to design and test the Dragon’s launch abort system . The SuperDraco firing was the ninth of ten milestones that are to be completed by SpaceX by around May 2012 and that were stipulated and funded by a Space Act Agreement (SAA) with NASA’s Commercial Crew Program (CCP).

“SpaceX and all our industry partners are being extremely innovative in their approaches to developing commercial transportation capabilities,” said Commercial Crew Program Manager Ed Mango in a NASA statement. “We are happy that our investment in SpaceX was met with success in the firing of its new engine.”

“Eight SuperDracos will be built into the sidewalls of the Dragon spacecraft, producing up to 120,000 pounds of axial thrust to quickly carry astronauts to safety should an emergency occur during launch,” said Elon Musk, SpaceX chief executive officer and chief technology officer in a statement. “Those engines will have the ability to deep throttle, providing astronauts with precise control and enormous power.”

“Crews will have the unprecedented ability to escape from danger at any point during the launch because the launch abort engines are integrated into the side walls of the vehicle,” Musk said. “With eight SuperDracos, if any one engine fails the abort still can be carried out successfully.”

SpaceX is one of four commercial firms working to develop a new human rated spacecraft with NASA funding. The other firms vying for a commercial crew contract are Boeing, Sierra Nevada and Blue Origin.

“SuperDraco engines represent the best of cutting edge technology,” says Musk. “These engines will power a revolutionarylaunch escape system that will make Dragon the safest spacecraft in history and enable it to land propulsively on Earth or another planet with pinpoint accuracy.”

The privately developed space taxi’s will eventually revive the capability to ferry American astronauts to and from the ISS that was totally lost when NASA’s Space Shuttle orbiters were forcibly retired before a replacement crew vehicle was ready to launch.

Because the US Congress slashed NASA’s commercial crew development funding by more than 50% -over $400 million – the first launch of a commercial space taxi is likely to be delayed several more years to about 2017. Until that time, all American astronauts must hitch a ride to the ISS aboard Russian Soyuz capsules.

This week the Russian manned space program suffered the latest in a string of failures when when technicians performing a crucial test mistakenly over pressurized and damaged the descent module of the next manned Soyuz vehicle set to fly to the ISS in late March, thereby forcing about a 45 day delay to the launch of the next manned Soyuz from Kazakhstan.

SpaceX Delays Upcoming 1st Dragon Launch to ISS

The first test launch of a commercially built spacecraft to the International Space Station has been delayed by its builder, Space Exploration Technologies or SpaceX, in order to carry out additional testing to ensure that the vehicle is fully ready for the high stakes Earth orbital mission.

SpaceX and NASA had been working towards a Feb. 7 launch date of the company’s Dragon spacecraft and announced the postponement in a statement today (Jan. 16).

A new target launch date has not been set and it is not known whether the delay amounts to a few days, weeks or more. The critical test flight has already been rescheduled several times and was originally planned for 2011.

The unmanned Dragon is a privately developed cargo vessel constructed by SpaceX under a $1.6 Billion contract with NASA to deliver supplies to the ISS and partially replace the transport to orbit capabilities that were fully lost following the retirement of the Space Shuttle in 2011.

“In preparation for the upcoming launch, SpaceX continues to conduct extensive testing and analysis, said SpaceX spokeswoman Kirstin Grantham in the statement.

“We [SpaceX] believe that there are a few areas that will benefit from additional work and will optimize the safety and success of this mission.”

“We are now working with NASA to establish a new target launch date, but note that we will continue to test and review data. We will launch when the vehicle is ready,” said Grantham.

This SpaceX Dragon will launch to the ISS sometime in 2012 on COTS2/3 mission. Protective fairings are installed over folded solar arrays, at the SpaceX Cape Canaveral launch site.

Dragon’s purpose is to ship food, water, provisions, equipment and science experiments to the ISS.

The demonstration flight – dubbed COTS 2/3 – will be the premiere test flight in NASA’s new strategy to resupply the ISS with privately developed rockets and cargo carriers under the Commercial Orbital Transportation Services (COTS) initiative.

The Dragon will blast off atop a Falcon 9 booster rocket also built by SpaceX and, if all goes well, conduct the first ever rendezvous and docking of a privately built spacecraft with the 1 million pound orbiting outpost.

After closely approaching the ISS, the crew will grapple Dragon with the station’s robotic arm and berth it to the Earth-facing port of the Harmony node.

“We’re very excited about it,” said ISS Commander Dan Burbank in a recent televised interview from space.

Since the demonstration mission also involves many other first time milestones for the Dragon such as the first flight with integrated solar arrays and the first ISS rendezvous, extra special care and extensive preparatory activities are prudent and absolutely mandatory.

NASA’s international partners, including Russia, must be consulted and agree that all engineering and safety requirements, issues and questions related to the docking by new space vehicles such as Dragon have been fully addressed and answered.

William Gerstenmaier, NASA’s associate administrator for the Human Exploration and Operations Mission Directorate recently stated that the launch date depends on completing all the work necessary to ensure safety and success, “There is still a significant amount of critical work to be completed before launch, but the teams have a sound plan to complete it.”

“As with all launches, we will adjust the launch date as needed to gain sufficient understanding of test and analysis results to ensure safety and mission success.”

“A successful mission will open up a new era in commercial cargo delivery to the international orbiting laboratory,” said Gerstenmaier.

SpaceX is also working on a modified version of the spacecraft, dubbed DragonRider, that could launch astronaut crews to the ISS in perhaps 3 to 5 years depending on the amount of NASA funding available, says SpaceX CEO and founder Elon Musk

The Dragon has grown its mighty wings

SpaceX’s Dragon spacecraft has gotten its wings and is set to soar to the International Space Station (ISS) in about a month. NASA and SpaceX are currently targeting a liftoff on Feb. 7 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

Dragon is a commercially developed unmanned cargo vessel constructed by SpaceX under a $1.6 Billion contract with NASA. The Dragon spacecraft will launch atop a Falcon 9 booster rocket also built by SpaceX, or Space Exploration Technologies.

The Feb. 7 demonstration flight – dubbed COTS 2/3 – represents the first test of NASA’s new strategy to resupply the ISS with privately developed rockets and cargo carriers under the Commercial Orbital Transportation Services (COTS) initiative.

Following the forced retirement of the Space Shuttle after Atlantis final flight in July 2011, NASA has no choice but to rely on private companies to loft virtually all of the US share of supplies and equipment to the ISS.

The Feb. 7 flight will be the first Dragon mission actually tasked to dock to the ISS and is also the first time that the Dragon will fly with deployable solar arrays. The twin arrays are the primary power source for the Dragon. They will be deployed a few minutes after launch, following Dragon separation from the Falcon 9 second stage.

The solar arrays can generate up to 5000 watts of power on a long term basis to run the sensors and communications systems, drive the heating and cooling systems and recharge the battery pack.

SpaceX designed, developed and manufactured the solar arrays in house with their own team of engineers. As with all space hardware, the arrays have been rigorously tested for hundreds of hours under the utterly harsh conditions that simulate the unforgiving environment of outer space, including thermal, vacuum, vibration, structural and electrical testing.

The two arrays were then shipped to Florida and have been attached to the side of the Dragon’s bottom trunk at SpaceX’s Cape Canaveral launch processing facilities. They are housed behind protective shielding until commanded to deploy in flight.

I’ve toured the SpaceX facilities several times and seen the Falcon 9 and Dragon capsule launching on Feb. 7. The young age and enthusiasm of the employees is impressive and quite evident.

NASA recently granted SpaceX the permission to combine the next two COTS demonstration flights into one mission and dock the Dragon at the ISS if all the rendezvous practice activities in the vicinity of the ISS are completed flawlessly.

The ISS crew is eagerly anticipating the arrival of Dragon, for whch they have long trained.

“We’re very excited about it,” said ISS Commander Dan Burbank in a televised interview from on board the ISS earlier this week.

The ISS crew will grapple the Dragon with the station’s robotic arm when it comes within reach and berth it to the Earth-facing port of the Harmony node.

“From the standpoint of a pilot it is a fun, interesting, very dynamic activity and we are very much looking forward to it,” Burbank said. “It is the start of a new era, having commercial vehicles that come to Station.”

Burbank is a US astronaut and captured stunning images of Comet Lovejoy from the ISS just before Christmas, collected here.

NASA announces Feb. 7 launch for 1st SpaceX Docking to ISS

SpaceX Dragon spacecraft approaches ISS on Test Flight set for Feb. 7, 2012 launch. During the SpaceX COTS 2/3 demonstration mission in February 2012, the objectives include Dragon demonstrating safe operations in the vicinity of the ISS. After successfully completing the COTS 2 rendezvous requirements, Dragon will receive approval to begin the COTS 3 activities, gradually approaching the ISS from the radial direction (toward the Earth), to within a few meters of the ISS.

Make or break time for NASA’s big bet on commercial space transportation is at last in view. NASA has announced Feb. 7, 2012 as the launch target date for the first attempt by SpaceX to dock the firms Dragon cargo resupply spacecraft to the International Space Station (ISS), pending final safety reviews.

The Feb. 7 flight will be the second of the so-called Commercial Orbital Transportation Services (COTS) demonstration flights to be conducted by Space Exploration Technologies, or SpaceX, under a contact with NASA.

Several months ago SpaceX had requested that the objectives of the next two COTS flights, known as COTS 2 and COTS 3, be merged into one very ambitious flight and allow the Dragon vehicle to actually dock at the ISS instead of only accomplishing a rendezvous test on the next flight and waiting until the third COTS flight to carry out the final docking attempt.

The Dragon will remain attached to the ISS for about one week and astronauts will unload the cargo. Then the spacecraft will depart, re-enter the Earth atmosphere splashdown in the Pacific Ocean off the coast of California.

“The cargo is hundreds of pounds of astronaut provisions,” SpaceX spokeswoman Kirstin Grantham told Universe Today.

“SpaceX has made incredible progress over the last several months preparing Dragon for its mission to the space station,” said William Gerstenmaier, NASA’s associate administrator for the Human Exploration and Operations Mission Directorate. “We look forward to a successful mission, which will open up a new era in commercial cargo delivery for this international orbiting laboratory.”

Since the forced retirement of NASA’s Space Shuttle following the final fight with orbiter Atlantis in July 2011 on the STS-135 mission, the US has had absolutely zero capability to launch either supplies or human crews to the massive orbiting complex, which is composed primarily of US components.

In a NASA statement, Gerstenmaier added, “There is still a significant amount of critical work to be completed before launch, but the teams have a sound plan to complete it and are prepared for unexpected challenges. As with all launches, we will adjust the launch date as needed to gain sufficient understanding of test and analysis results to ensure safety and mission success.”

SpaceX lofted the COTS 1 flight a year ago on Dec. 8, 2010 and became the first private company to successfully launch and return a spacecraft from Earth orbit. SpaceX assembled both the Falcon 9 booster rocket and the Dragon cargo vessel from US built components.

The new demonstration flight is now dubbed COTS 2/3. The objectives include Dragon safely demonstrating all COTS 2 operations in the vicinity of the ISS by conducting check out procedures and a series of rendezvous operations at a distance of approximately two miles and the ability to abort if necessary.

The European ATV and Japanese HTV cargo vessels carried out a similar series of tests during their respective first flights.

After accomplishing all the rendezvous tasks, Dragon will then receive approval to begin the COTS 3 activities, gradually approaching the ISS from below to within a few meters.

Specially trained astronauts working in the Cupola will then reach out and grapple Dragon with the Station’s robotic arm and then maneuver it carefully into place onto the Earth-facing side of the Harmony node. The operations are expected to take several hours.

If successful, the Feb. 7 SpaceX demonstration flight will become the first commercial mission to visit the ISS and vindicate the advocates of commercial space transportation who contend that allowing private companies to compete for contracts to provide cargo delivery services to the ISS will result in dramatically reduced costs and risks and increased efficiencies.

The new commercial paradigm would also thereby allow NASA to focus more of its scarce funds on research activities to come up with the next breakthroughs enabling bolder missions to deep space.

If the flight fails, then the future of the ISS could be in serious jeopardy in the medium to long term because there would not be sufficient alternative launch cargo capacity to maintain the research and living requirements for a full crew complement of six residents aboard the orbiting laboratory.

Feb. 7 represents nothing less than ‘High Stakes on the High Frontier’.

NASA is all about bold objectives in space exploration in both the manned and robotic arenas – and that’s perfectly represented by the agencies huge gamble with the commercial cargo and commercial crew initiatives.

Revolutionary Air-Launched Commercial Rocket to Orbit Announced by Microsoft Billionaire Paul Allen

Stratolaunch Systems Carrier Aircraft - Air Launch to Orbit Space Launch System. Developed by Scaled Composites, the aircraft manufacturer and assembler founded by Burt Rutan. The carrier will loft and drop the 500,000 multistage SpaceX rocket that will propel payloads to orbit at dramatically reduced costs. It will be the largest aircraft ever flown with a wing span of 385 feet and weighing 1.2 million pounds. Credit: Stratolaunch Systems. Watch complete video below.

A mega quartet of luminaries led by Microsoft co-founder Paul G. Allen and legendary aerospace designer Burt Rutan have joined forces to create a revolutionary new approach to space travel. This new privately funded venture entails the development of a mammoth air-launched space transportation system that aims to dramatically cut the high costs and risks of launching both cargo and human crews to low Earth orbit.

Allen and Rutan are teaming up with Elon Musk, founder of Space Exploration Technologies Corp, or SpaceX, and Michael Griffin, former NASA Administrator, to build the world’s largest aircraft ever flown and use it as a platform to loft a multi-stage SpaceX rocket that will deliver a payload of some 13,500 pounds into earth orbit, about the same class as a Delta II.

Allen and Rutan hope to build upon the spaceflight revolution that they pioneered with the suborbital SpaceShipOne in 2004, which was the first privately funded spaceship to reach the edge of space, and now take the critical next step and actually vault all the way to orbit.


Video Caption: Stratolaunch Systems is pioneering innovative solutions to revolutionize space transportation to orbit.

To accomplish this innovative leap, Allen and Rutan, announced the formation of a new company, funded by Allen, called Stratolaunch Systems at a press briefing today, Dec. 13, held in Seattle, WA. Allen is a billionaire and philanthropist who has funded a host of projects to advance science,

“Our national aspirations for space exploration have been receding,” Allen lamented at the start of the briefing. “This year saw the end of NASA’s space shuttle program. Constellation, which would have taken us back to the moon, has been mothballed as well. For the first time since John Glenn, America cannot fly its own astronauts into space.”

“With government funded spaceflight diminishing, there’s a much expanded opportunity for privately funded efforts.”

Rutan said that Stratolaunch will build a 1.2 million pound carrier aircraft sporting a wingspan of 385 feet – longer than a football field – and which will be powered by six 747 engines on takeoff. The carrier will be a twin fuselage vehicle, like the WhiteKnight developed by Rutan to launch SpaceShipOne.

Air launch of SpaceX rocket to orbit

The 120 foot long SpaceX rocket, weighing up to 490,000 pounds, will be slung in between and dropped at an altitude of about 30,000 feet for the remaining ascent to orbit.

SpaceX will construct a shorter, less powerful version of the firms existing Falcon 9 rocket, which may be either a Falcon 4 or Falcon 5 depending on specifications.

The new launch system will operate from a large airport or spaceport like the Kennedy Space Center, require a 12,000 feet long runway for takeoff and landing and be capable of flying up to 1,300 nautical miles to the payload’s launch point. Crews aboard the huge carrier aircraft will also conduct the countdown and firing of the booster and will monitor payload blasting to orbit.

“I have long dreamed about taking the next big step in private space flight after the success of SpaceShipOne – to offer a flexible, orbital space delivery system,” Allen said. “We are at the dawn of radical change in the space launch industry. Stratolaunch Systems is pioneering an innovative solution that will revolutionize space travel.”

The goal of Stratolaunch is to “bring airport-like operations to the launch of commercial and government payloads and, eventually, human missions,” according to a company statement.

Plans call for a first orbital flight within five years by around 2016. Test flights could begin around 2015.

“We believe this technology has the potential to someday make spaceflight routine by removing many of the constraints associated with ground launched rockets,” said Mike Griffin. “Our system will also provide the flexibility to launch from a large variety of locations.”

Mike Griffin added that the venture is aiming for the small to medium class payload market similar to what has been served by the venerable Delta II rocket, which is now being retired after decades of service.

“NASA’s science satellites could also be lofted by Stratolaunch.”

“At some point this vehicle could loft a crew of say six people,” Griffin stated.

“This is an exciting day,” concluded Allen.

“Stratolaunch will keep America at the forefront of space exploration and give tomorrow’s children something to search for in the night sky and dream about. Work has already started on our project at the Mojave Spaceport.”

Science Rich Gale Crater and NASA’s Curiosity Mars Rover in Glorious 3-D – Touchdown in a Habitable Zone

Gale Crater in 3 D - Curiosity Mars Rover Landing site. NASA's most advanced mobile robotic laboratory, the Mars Science Laboratory carrying the Curiosity rover, is set to launch atop an Atlas V rocket on Nov. 26 at 10:02 a.m. EST on a mission to examine Gale Crater on Mars that shows geologic evidence of minerals that formed in flowing liquid water.

[/caption]

Curiosity, NASA’s next Mars rover is on target to launch this Saturday, Nov 26 from the Florida Space Coast in less than four days at 10:02 a.m. NASA is utilizing a first-of- its- kind pinpoint landing system for targeting Curiosity to touchdown inside Gale Crater – one of the most scientifically interesting locations on the Red Planet because it exhibits exposures of clay minerals that formed in the presence of neutral liquid water that could be conducive to the genesis of life.

For a dramatic glimpse of the ragged and richly varied terrain of the 154 kilometer (96 mile) wide Gale Crater check out the glorious 3 D stereo image above. Another 3 D image, below, shows Curiosity being tested at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena. Calif., earlier this year.

“From NASA’s prior missions we’ve learned that Mars is a dynamic planet,” said Michael Meyer, lead scientist for NASA’s Mars exploration program, at a pre-launch briefing for reporters at the Kennedy Space Center.

“We’ve learned that it has a history where it was warm and wet at the same time that life started here on Earth. And we know it’s undergone a massive transition from that more benign time to what it is today.”

“Mars is worth exploring because of the potential for its having been habitable, at least in its past,” said Meyer.

Gale crater is dominated by a layered mountain rising some 5 km (3 mi) above the crater floor, readily apparent in the images above and below.

Topography of Gale Crater
Color coding in this image of Gale Crater on Mars represents differences in elevation. The vertical difference from a low point inside the landing ellipse for NASA's Curiosity Mars Science Laboratory (yellow dot) to a high point on the mountain inside the crater (red dot) is about 3 miles (5 kilometers).

“Liquid water was not short term in the past on ancient Mars. It has a role in carving out channels and depositing sediments in the past within craters that were carried by the water,” said Bethany Ehlmann of NASA’s Jet Propulsion Laboratory in Pasadena, Calif, at the briefing.

“Clays and carbonates are minerals that form in the presence of liquid water. The presence of clays in particular indicate the long-term presence of water interacting with the rocks and causing alteration of minerals. Clays also have water in their chemical structure as hydrates.”

NASA is targeting a landing ellipse – 20 by 25 kilometers (12.4 miles by 15.5 miles) – located in the northern portion of Gale and visible in the foreground.

The landing site was selected from some 60 candidates by the science team and NASA because it features an alluvial fan likely formed by water-carried sediments containing the clay minerals and is highlighted in another image below.

The lower layers of the nearby mountain — within driving distance for Curiosity — contain clay minerals and sulfates indicating a wet history on ancient Mars.

“Gale Crater is about as big as the Los Angeles basin,” said MSL project scientist John Grotzinger of JPL and Caltech, at the briefing. The mountain in the middle is as high as Mt Whitney, the tallest mountain in the lower 48 US states.”

“Over the course of the mission me might be about to go to the top of the nearby mound. At the base of the mound we see strata that are composed of clays.

“In one location, we can drive the rover through all these successive different environments and sample these different periods in Martian history,” explained Grotzinger.

All systems are “GO” at this time and the weather outlook currently looks favorable for an on time liftoff of Curiosity atop an Atlas V rocket from Space Launch Complex 41.

NASA has recently posted the latest update as to how the Commercial Crew Development 2 (CCDev2) program is doing in terms of meeting milestones laid out at the program’s inception. According to the third status report that was released by NASA, CCDev2’s partners continue to meet these objectives. The space agency has worked to provide regular updates about the program’s progress.

“There is a lot happening in NASA’s commercial crew and cargo programs and we want to make sure the public and our stakeholders are informed about the progress industry is making,” said Phil McAlister, NASA’s director of commercial spaceflight development. “It’s exciting to see these spaceflight concepts move forward.”

One of the primary objectives of the Commercial Crew Development program is to cut down the length of time that NASA is forced to rely on Russia for access to the International Space Station. Photo Credit: NASA

Reports on the progress of commercial crew are issued on a bi-monthly basis. The reports are directed toward the primary stakeholder of this program, the U.S. taxpayer. NASA has invested both financial and technical assets in an effort to accelerate the development of commercial access to orbit.

This report came out at the same time as Space Exploration Technologies’ (SpaceX) CEO, Elon Musk, testified before the U.S. House Science, Space, and Technology Committee regarding NASA’s commercial crewed program.

SpaceX itself has been awarded $75 million under the CCDev program to develop a launch abort system, known as “DragonRider” that would enable the company’s Dragon spacecraft to transport astronauts. SpaceX was awarded $1.6 billion under the Commercial Orbital Transportation Services or COTS contract with NASA. Under the COTS contract, SpaceX must fly three demonstration flights as well as nine cargo delivery flights to the orbiting outpost. SpaceX is currently working to combine the second and third demonstration flights into one mission, currently scheduled to fly at the end of this year.

During Musk’s comments to the House, he highlighted his company’s efforts to make space travel more accessible.

“America’s endeavors in space are truly inspirational. I deeply believe that human spaceflight is one of the great achievements of humankind. Although NASA only sent a handful of people to the moon, it felt like we all went,” Musk said in a written statement. “We vicariously shared in the adventure and achievement. My goal, and the goal of SpaceX, is to help create the technology so that more can share in that great adventure.”

To date, SpaceX is the only company to have demonstrated the capacity of their launch vehicle as well as a spacecraft. The company launched the first of its Dragon spacecraft atop of its Falcon 9 rocket this past December. The Dragon completed two orbits successfully before splashing down safely off the coast of California.

NASA is relying on companies like SpaceX to develop commercial crew transportation capabilities that could one day send astronauts to and from the International Space Station (ISS). It is hoped that CCDev2 will help reduce U.S. dependence on Russia’s Soyuz spacecraft for access to the ISS. Allowing commercial companies to take over the responsibility of sending crews to the ISS might also allow the space agency focus on sending astronauts beyond low-Earth-orbit for the first time in four decades.

CAPE CANAVERAL, Fla – Space Exploration Technologies (SpaceX) welcomed a new guest to Space Launch Complex 40 (SLC-40) on Sunday – the next Dragon spacecraft that is set to launch later this year. Members of the media were invited to a photo opportunity to chronicle the Dragon spacecraft’s arrival which had been delayed a day due to issues with travel permits.

The Dragon that arrived on Sunday is destined to fly to the International Space Station (ISS). It will be the first time that a private firm docks with the space station. The COTS Demo 2 Dragon was shipped from SpaceX’s facilities in Hawthorne, California to Cape Canaveral in Florida.

The Falcon 9 rocket, with its Dragon spacecraft payload, is currently scheduled to launch from Cape Canaveral Air Force Station’s SLC-40 on Dec. 19. If all goes as it is currently planned the Dragon will maneuver along side of the orbiting laboratory where the space station’s robot Canadarm 2 will grapple the unmanned spacecraft it and dock it with the station.

“When it comes to the launch day, NASA will determine that, we’re pushing to launch on Dec. 19, but the final “go” date is set by NASA and the range,” said SpaceX’s Vice-President for Communications Bobby Block. “We are currently working to conduct a wet dress rehearsal on November 21st.”

SpaceX recently passed a Preliminary Draft Review (PDR) of the Dragon’s Launch Abort System (LAS). This system, which pulls astronauts and their spacecraft to safety in case of some problem with the Falcon 9 launch vehicle, is unlike other systems of its type. Normal abort systems are essentially small rockets affixed to the top of the spacecraft (which is normally on top of the rocket). Not so with SpaceX’s design, dubbed DragonRider – it will be built into the walls of the spacecraft.

The reason for the difference in the abort system’s design is twofold. First, it will drive the costs down (Dragon is being developed as a reusable spacecraft) -whereas traditional abort systems are not capable of being reused. Secondly the system could one day be used as a potential means of landing spacecraft on other terrestrial worlds, such as the planet Mars.

This will mark the second demonstration flight that SpaceX will have flown to accomplish the objectives laid out in the Commercial Orbital Transportations Services or COTS contract. The $1.6 billion contract is an effort to ensure that needed cargo is delivered to the station safely and in a timely fashion.

SpaceX so far has launched two of its Falcon 9 rockets – both in 2010. The first flight occurred on June 4, 2010 with the second being launched on Dec. 8, 2010. It was on this second flight that SpaceX became the first private entity to launch a spacecraft into orbit and then safely recover it after it had successfully orbited the Earth twice. Before this only nations were capable of achieving this feat.

“This is very exciting, our last launch was about a year ago, so to have a fully-operational Dragon up-and-ready to make a historic docking to the International Space Station it’s terrifically exciting.” Block said.

SpaceX Completes Crucial Milestone Toward Launching Astronauts

Space Exploration Technologies (SpaceX) is now one more step closer to sending astronauts to orbit. The commercial space firm announced today that it has completed a successful review of the company’s launch abort system (LAS). SpaceX’s LAS, dubbed “DragonRider” is designed differently than abort systems that have been used in the past.

The first review of the system’s design and its subsequent approval by NASA represents a step toward the realization of the space agency’s current objective of having commercial companies provide access to the International Space Station (ISS) while it focuses on sending astronauts beyond low-Earth-orbit (LEO) for the first time in four decades.

“Each milestone we complete brings the United States one step closer to once again having domestic human spaceflight capability,” said former astronaut Garrett Reisman, who is one of the two program leads who are working on SpaceX’s DragonRider program.

With the space shuttle program over and its fleet of orbiters headed to museums, the United States is paying Russia an estimated $63 million per seat on its Soyuz spacecraft. SpaceX has estimated that, by comparison, flights on a man-rated version of its Dragon spacecraft would cost approximately $20 million. Despite the dramatically lower cost, SpaceX has emphatically stated that safety is one of the key drivers of its spacecraft.

“Dragon’s integrated launch abort system provides astronauts with the ability to safely escape from the beginning of the launch until the rocket reaches orbit,” said David Giger, the other lead on the DragonRider program. “This level of protection is unprecedented in manned spaceflight history.”

SpaceX had already met three of NASA’s milestones under the Commercial Crew Development (CCDev) contract that the company has signed into with the U.S. space agency. With the Preliminary Design Review or PDR completed of the abort system SpaceX can now rack up another milestone that it has met.

Unlike conventional abort systems, which are essentially small, powerful rockets that are attached to the top of the spacecraft, Dragon’s LAS is actually built into the walls of the Dragon. This is not an effort just to make the spacecraft’s abort system unique – rather it is meant as a cost-cutting measure. The Dragon is intended to be reusable, as such its abort system needed to be capable of being reused on later flights as well. Traditional LAS simply do not allow for that. With every successful launch by conventional means – the LAS is lost.

SpaceX is also working to see that this system not only can save astronaut lives in the advent of an emergency – but that it can actually allow the spacecraft to conduct pinpoint landings one day. Not just on Earth – but possibly other terrestrial bodies – including Mars.

To date, SpaceX has launched two of its Falcon 9 launch vehicles. The first occurred on June 4 of 2010 and the second, and the first under the Commercial Orbital Transportation Services (COTS) contract took place six months later on Dec. 8. This second mission was the first to include a Dragon spacecraft, which was recovered in the Pacific Ocean off the coast of California after successfully completing two orbits.

“We have accomplished these four milestones on time and budget, while this is incredibly important, it is business as usual for SpaceX,” said SpaceX’s Vice-President for Communications Bobby Block during an interview. “These are being completed under a Space Act Agreement that demonstrates the innovative and efficient nature of what can be accomplished when the commercial sector and NASA work together.”
