Bigelow Aerospace and United Launch Alliance (ULA) announced they are joining forces to develop and launch the world’s first commercial space habitat to Low Earth Orbit (LEO) by 2020 – potentially as a huge and revolutionary new addition to the International Space Station (ISS).

The expandable habitat will be based on the Bigelow Aerospace B330 module and would be carried to orbit on the most powerful version of ULA’s venerable Atlas V rocket.

Robert Bigelow, founder and president of Bigelow Aerospace, and Tory Bruno, ULA president and CEO announced the partnership on the fully commercial space habitat during a joint media briefing held at the 32nd Space Symposium in Colorado Springs, Colorado on April 11.

“We could not be more pleased than to partner with Bigelow Aerospace and reserve a launch slot on our manifest for this revolutionary mission,” said Tory Bruno, ULA president and CEO.

The B330 boasts an interior volume of 330 cubic meters (12,000 cu ft). It measures 57 feet (17.3 m) in length, weighs 20 tons and offers a design life span of 20 years.

If NASA agrees to attach the B330 to the ISS, the stations habitable volume would grow by a whopping 30% in one giant step.

“The alliance represents the first-ever commercial partnership between a launch provider and a habitat provider,” according to ULA.

The advantage of expandable habitats is that they offer a much better volume to weight ratio compared to standard rigid structures, such as all of the current ISS pressurized modules.

The station based B330 concept is named XBASE or Expandable Bigelow Advanced Station Enhancement.

The additional volume would enable a significant increase in the orbiting outposts ability to support research and development operations and manufacturing processes for NASA and commercial users.

Bigelow further views the B330 and follow on modules as a potential destination for space tourism and a beneficial component for human missions to the Moon and Mars.

“We are exploring options for the location of the initial B330 including discussions with NASA on the possibility of attaching it to the International Space Station (ISS),” said Robert Bigelow, founder and president of Bigelow Aerospace.

“In that configuration, the B330 will enlarge the station’s volume by 30% and function as a multipurpose testbed in support of NASA’s exploration goals as well as provide significant commercial opportunities. The working name for this module is XBASE or Expandable Bigelow Advanced Station Enhancement.”

Bigelow said his firm plans to build two B330 modules by 2020.

The B330 would be tucked inside the cavernous payload fairing of the Atlas V which would launch in the 552 configuration with 5 meter diameter fairing with 5 solid rocket booster attached to the first stage and a dual engine Centaur second stage.

“When looking for a vehicle to launch our large, unique spacecraft, ULA provides a heritage of solid mission success, schedule certainty and a cost effective solution,” says Bigelow.

The SpaceX falcon 9 fairing is not big enough to house the B330.

“SpaceX, they do not have the capability with the fairing size that is necessary to accommodate the B330. So that is not even a choice,” Bigelow stated.

The B330 partnership announcement follows hot on the heels of last weeks successful launch of Bigelow’s experimental BEAM expandable module on a SpaceX Falcon 9 rocket on a mission to the ISS on April 8.

BEAM is tucked inside the rear truck section of the SpaceX Dragon now berthed at the station. It will soon be attached to a side port on the Harmony module.

“This innovative and game-changing advance will dramatically increase opportunities for space research in fields like materials, medicine and biology,” said Bruno.

“It enables destinations in space for countries, corporations and even individuals far beyond what is available today, effectively democratizing space. We can’t begin to imagine the future potential of affordable real estate in space.”

The B330 could also function as a free flyer but would work best at the station, Bigelow noted at the briefing.

Both of the commercial space taxis being developed under NASA’s commercial crew program (CCP) could dock at the B330; the Boeing Starliner and the SpaceX crew Dragon, Bigelow stated.

Multiple B330 modules could also be joined together in orbit to form a free flying commercial space station.

Atlas V Engine Anomaly Forces Thrust Makeup During Cygnus Launch, Next Flight Delayed

KENNEDY SPACE CENTER, FL – This week’s Atlas V rocket launch of a Cygnus cargo ship to the International Space Station (ISS) apparently experienced a first stage engine anomaly during the climb to space that required a longer firing of the boosters upper stage engine so the payload could successfully achieve the required orbit.

The stunningly beautiful nighttime blastoff of the United Launch Alliance (ULA) Atlas V from the Florida space coast on Tuesday, March 22, was not quite as flawless as initially thought and marred by the early engine shutdown which has now forced a postponement of the next planned Atlas V launch as company engineers painstakingly evaluate the data.

“The Centaur [upper stage] burned for longer than planned,” Lyn Chassagne, spokesperson for rocket maker ULA, told Universe Today.

“The ULA engineering team is reviewing the data to determine the root cause of the occurrence.”

The Centaur RL10C-1 powerplant had to make up for a thrust and velocity deficiency resulting from a 6 second shorter than planned firing of the Atlas V’s first stage RD-180 engines.

Indeed the Centaur had to fire for a minute longer than planned to inject Cygnus into its target orbit.

“The first stage cut-off occurred approximately 6 seconds early, however the Centaur was able to burn an additional approximately 60 seconds longer and achieve mission success, delivering Cygnus to its required orbit.”

“The team is evaluating the occurrence as part of the standard post-flight data analysis. Following successful spacecraft separation, Centaur performed a disposal burn,” Chessagne elaborated.

The two stage ULA Atlas V lifted off on time at 11:05 p.m. EDT on Tuesday, March 22, 2016 from Space Launch Complex 41 on Cape Canaveral Air Force Station, Fl, under a picturesque moonlit sky carrying an Orbital ATK Cygnus spacecraft on a resupply mission for NASA to the ISS.

Following a 21-minute ascent, the S.S. Rick Husband Cygnus spacecraft was successfully deployed into its intended orbit approximately 144 miles above the Earth, inclined at 51.6 degrees to the equator, Orbital ATK confirmed in a statement.

The Russian-made RD AMROSS RD-180 engines power the Atlas V first stage and the dual nozzle powerplants have been completely reliable in 62 Atlas launches to date.

The RD-180s were supposed to fire for 255.5 seconds, or just over 4 minutes. But instead they shut down prematurely resulting in decreased velocity that had to be supplemented by the Centaur RL10C-1 to get to the intended orbit need to reach the orbiting outpost.

The liquid oxygen/liquid hydrogen fueled Aerojet Rocketdyne RL10C-1 engine was planned to fire for 818 seconds or about 13.6 minutes. The single engine produces 22,900 lbf of thrust.

The cause of the first stage engine shortfall has not been announced. ULA has launched a thorough investigation to determine root cause as to whether for example it’s the RD-180 engine itself, a faulty sensor, fuel related, ground support equipment or a myriad of some other rocket components or issues.

Although the Atlas V did successfully launch and deploy the commercial Cygnus CRS-6/OA-6 spacecraft into the required orbit, the Centaur was pressed into extra duty in real time to propel the payload.

The Atlas V first and second stages are preprogrammed to swiftly react to a wide range of anomalous situations to account for the unexpected. The rocket and launch teams conduct countless simulations to react to off nominal situations.

“The Atlas V’s robust system design, software and vehicle margins enabled the successful outcome for this mission,” Chassagne said.

“As with all launches, we will continue to focus on mission success and work to meet our customer’s needs.”

At the post launch media briefing, ULA program manager for NASA missions Vern Thorp, said that “ in a little over 20 minutes we went from liftoff to delivering Cygnus into exactly the orbit that it wanted to be in. This was our second successful cargo mission [for Orbital ATK] since December.”

“We were targeting a 230 kilometer circular orbit and we came very close to that as we normally do, just a fraction of a kilometer off. Well within the normal dispersions.”
“We nailed it. We got Cygnus where it wants to go.”

Asked about the Centaur he said that the prelaunch predictions are based on preliminary trajectories and can vary depending on the actual conditions at launch.

“What I do know is that Centaur nailed the orbit. Like every mission, we’re going to do a very, very detailed post-flight review. We always do and we always have done that. That’s to make sure that everything performed properly. From everything we’ve seen so far, the mission was pretty nominal.”

Now as a result of the post-flight review into the engine anomaly and velocity shortfall, the next launch of the “Atlas V carrying the MUOS-5 mission for the U.S. Navy and the U.S. Air Force has been delayed to no earlier than May 12,” Chassagne added.

ULA needs to “further review the data anomaly experienced during the OA-6 mission.”

“The delay will allow additional time to review the data and to confirm readiness for the MUOS-5 mission.”

The Atlas V/MUOS-5 mission will lift off from the same pad at Space Launch Complex 41 on Cape Canaveral Air Force Station, Fl, whenever a launch target date is announced by ULA.

Meanwhile the Cygnus CRS-6/OA-6 spacecraft continues chasing down the ISS for a planned arrival early Saturday morning, March 26.

The spacecraft will arrive at the station on Saturday, March 26. At that time Expedition 47 Commander Tim Kopra of NASA and Flight Engineer Tim Peake of ESA (European Space Agency) will grapple Cygnus, using the space station’s robotic arm, at approximately 6:40 a.m.

NASA TV coverage of rendezvous and grapple will begin at 5:30 a.m.

The Cygnus CRS-6/OA-6 payload of more than 16,000 pounds (7200 kg) weighed in as the heaviest payload to launch on an Atlas V to date.

Stunning Nighttime Cygnus Freighter Rockets to ISS Stocked with Science Mesmerizing Spectators

KENNEDY SPACE CENTER, FL – A stunningly beautiful nighttime launch mesmerized delighted spectators as it roared off a Florida space coast launch pad late Tuesday night, March 22, on a mission for NASA stocked with over three tons of science and supplies bound for the multinational crews working aboard the International Space Station (ISS).

A United Launch Alliance (ULA) Atlas V rocketed raced to orbit from Cape Canaveral Air Force Station, Fl, carrying an enlarged Cygnus commercial resupply spacecraft on the Orbital ATK CRS-6 mission to the ISS.

The venerable Atlas V lifted off right on target at 11:05 p.m. EDT from Space Launch Complex 41 into a picturesque moonlit sky that magnificently illuminated the scattered thin clouds hovering over the seaside launch pad for the hordes of excited folks and families lining the beaches and lucky to witness what may be history’s last launch of a Cygnus from Florida.

Future liftoffs of the private Orbital ATK Cygnus supply truck designed to stock the station will return to their original launch site on Virginia’s eastern shore starting with the next mission for their NASA customer sometime this summer.

Cygnus launches to the ISS normally start from NASA’s Wallops Flight Facility in Virginia.

But a catastrophic failure of the Orbital ATK Antares rocket moments after liftoff on Oct. 28, 2014, forced Orbital to seek and book an alternative launch vehicle while the company redesigned and reengined Antares first stage with new powerful powerplants for the ride to orbit.

The Cygnus spacecraft will arrive at the station on Saturday, March 26, at which time Expedition 47 Commander Tim Kopra of NASA and Flight Engineer Tim Peake of ESA (European Space Agency) will grapple Cygnus, using the space station’s robotic arm, at approximately 6:40 a.m. NASA TV coverage of rendezvous and grapple will begin at 5:30 a.m.

The commercial Cygnus cargo freighter was built by Orbital ATK, based in Dulles, Virginia.

This flight is also known as OA-6 and is being launched under terms of the firm’s Commercial Resupply Services (CRS) contract with NASA. It also counts as Orbital ATK’s fifth cargo delivery mission to the space station.

OA-6 is loaded with 3513 kg (7700 pounds) of science experiments and hardware, crew supplies, spare parts, gear and station hardware to the orbital laboratory in support over 250 research experiments being conducted on board by the Expedition 47 and 48 crews.

About a quarter of the cargo is devoted to science and research gear. The cargo includes 3279 kg of science investigations, 1139 kg of crew supplies, 1108 kg of vehicle hardware, 157 kg of spacewalk equipment, and 98 kg of computer resources.
Here a NASA description of a few of the scientific highlights:

– Gecko Gripper, testing a mechanism similar to the tiny hairs on geckos’ feet that lets them stick to surfaces using an adhesive that doesn’t wear off,

– Strata-1, designed to evaluate how soil on small, airless bodies such as asteroids behaves in microgravity.

– Meteor, an instrument to evaluate from space the chemical composition of meteors entering Earth’s atmosphere. The instrument is being re-flown following its loss on earlier supply missions.

– Saffire, which will set a large fire inside the Cygnus in an unprecedented study to see how large fires behave in space. The research is vital to selecting systems and designing procedures future crews of long-duration missions can use for fighting fires.

– Cygnus is carrying more than two dozen nanosatellites that will be ejected from either the spacecraft or the station at various times during the mission to evaluate a range of technology and science including Earth observations.

Here a cool video prelaunch look at Cygnus and me in the NASA Kennedy Space Center clean room discussing the Meteor experiment:

When the ISS Expedition 47 crew members open the hatch, they will be greeted with a sign noting the spacecraft was named ‘SS Rick Husband’ in honor of the STS-107 mission commander.

Cygnus will spend approximately two months docked at the ISS.

OA-6 is only the second Cygnus to be launched atop a ULA Atlas V rocket, following the OA-4 mission last December.

The CRS-6/OA-6 flight is also the second flight of the enhanced Cygnus variant, that is over 1 meter longer and sports 50% more volume capability.

Thus it is capable of carrying a much heavier payload of some 3500 kg (7700 lbs) vs. a maximum of 2300 kg (5070 lbs) for the standard version.
