     Genesis II Completes 10,000 Orbits
     April 25th, 2009

(Bigelow Aerospace) - Genesis II, the second prototype expandable space habitat launched by Bigelow Aerospace on June 28, 2007, has completed its 10,000th orbit around the Earth. Following the first spacecraft Genesis I, this unmanned vehicle demonstrates the continued development of future space stations technologies.
Orbiting 665 days and having traveled close to 270 million miles, Genesis II has been busy transmitting pressure, temperature and radiation data to the mission operations staff in Las Vegas. We are also conducting long term testing of systems such as lighting, air circulation, and pressure monitoring systems. In addition, the expanded camera configuration has provided over 51,000 images consisting of the inside of the spacecraft, the external micro-meteoroid shielding, and the Earth.
Genesis II was inserted into the same orbit as Genesis I. However, due to natural orbital decay, Genesis II is currently at a slightly higher altitude. Based on lifetime estimates, Genesis II and Genesis I will be in orbit for many more years.
Right now, the Bigelow Aerospace staff and their contractors continue their hard work on future commercial space habitats.

NASA considers ISS Bigelow module
DATE:09/09/09   SOURCE:Flightglobal.com

By Rob Coppinger

NASA is considering attaching a Bigelow Aerospace inflatable module to the International Space Station, in a return to a concept the agency had more than a decade ago.

In 1997 the US space agency examined the possible attachment of its Transhab inflatable module to the ISS, but abandoned the technology project. Transhab would have been used for crew quarters.

Bigelow took the NASA Transhab technology and developed it for its own orbital complex concept and launched two technology demonstrators, Genesis I and II, which were successfully launched using Russian rockets in 2006 and 2007.

From 2012 Bigelow wants to lease to governments, companies and tourists the use of its private space stations for research and recreation.

In 2007 Bigelow Aerospace founder Robert Bigelow announced an $11.9 million price tag for four weeks at his space station in 2007 dollars, excluding the cost of transport.

However, internal NASA documents passed to Flightglobal show the US space agency is now interested in attaching a Bigelow module, but neither the company or NASA were available for comment.

The interest in the Bigelow technology follows NASA's decision to permanently attach its Italian-designed and built Raffaello multipurpose logistics module to the ISS.

Raffaello, expected to arrive in September 2010 on the final Space Shuttle mission, will be filled with spares to overcome problems with station logistics once the Shuttle fleet is retired.

In the Johnson Space Center's 8 September edition of its 8th Floor newsletter it is stated that Raffaello will be attached at the space station's Node 1 nadir port, which faces the Earth's surface.

The next major module for the ISS, Node 3, will be delivered in February 2010 and that is also to be attached to Node 1, also known as Unity.

Node 1 has six ports. Five are already in use, for the Z1 truss, the US laboratory module called Destiny, an airlock and two pressurised mating adaptors.

One of the adaptors links Unity to Russia's Zarya module while the other docks the Shuttle. Node 3, also known as Tranquility, will be docked to Node 1 and the Node 1 pressurised mating adaptor used for docking Shuttle will be attached to it instead.

Arriving in September 2010 Raffaello will take up the sixth port, which will be the nadir.

补遗(2009-08-14):Bigelow有意建造轻型简约的猎户座飞船--"Orion Lite"

Nevada Company Pitches 'Lite' Concept for NASA's New Spaceship
By Amy Klamper
Space News Staff Writer
posted: 14 August 2009
09:09 am ET


A stripped down version of NASA's future spaceship designed by a Nevada-based company could be ready as soon as 2013, according to the Bigelow Aerospace, the private company proposing to build it.

A Bigelow official flew to Denver in July to privately brief a White House-charted panel on the suggested design based on the planned Orion Crew Exploration Vehicle, which will carry passengers to and from low Earth orbit.

Such a system is crucial to Bigelow's plans for deploying Sundancer, an inflatable space station module the North Las Vegas, Nev.-based firm is building based on NASA's Transhab design. In search of the means to transport paying passengers to Sundancer, Bigelow has spent the past two years working with Denver-based United Launch Alliance to study a human-rated version of the Atlas 5 rocket.

"Orion Lite"

But it was not until last month that Bigelow quietly unveiled the "Orion Lite" concept in a private briefing to former Lockheed Martin Chief Executive Norm Augustine and his White House-charted committee tasked in May with developing a range of options for an affordable and sustainable U.S. human spaceflight program.

Bigelow's crew capsule design is modeled on the Orion vehicle that Lockheed Martin — one of United Launch Alliance's corporate parents — is developing for NASA.

In a July 30 interview with Space News, Mike Gold, director of Bigelow's Washington office, said he believes a low Earth-orbit optimized version of Orion could be ready to launch atop a human-rated version of the Atlas 5 within three or four years — much sooner than NASA's discredited March 2015 target for the first crewed launch of Orion and its Ares I rocket.

Gold said the Bigelow capsule would have the same outer mold line as NASA's 16-foot (5-meter) wide Orion and possibly the same internal pressure vessel, but little else in common.

Lighter Capsule

For starters, NASA expects the lunar-capable Orion crew capsule and propellant-laden service module to weigh well in excess of about 40,000 pounds (20,000 kg). Gold would not provide weight or cost estimates for Bigelow's Orion Lite concept, but said the envisioned vehicle would be light enough to launch atop an Atlas 5 with a twin-engine Centaur upper stage but no strap-on solid-rocket boosters. This configuration, known as the 402, is capable of lofting 27,557 pounds (12,500 kg) into low Earth orbit.

Gold said the Bigelow capsule would also be capable of launching atop the Falcon 9 rocket Hawthorne, Calif.-based Space Exploration Technologies (SpaceX) hopes to debut this year.

"I don't think there's any question that a commercial capsule can be constructed, tested and launched years before the existing Orion plan will come together, if it ever does," Gold said. "We're moving beyond Orion-Ares at this point."

A start-up venture founded in the late 1990s by real estate mogul Robert Bigelow, the company currently has two subscale expandable space modules in orbit. The privately financed Genesis 1 and Genesis 2 modules were launched in 2006 and 2007, respectively, from Russia aboard Dnepr rockets.

A combination of rising Russian launch prices and the success of Genesis 1 and Genesis 2 compelled the company to skip the launch of additional subscale demonstrators and accelerate development of Sundancer, a six-person space station that could grow to accommodate 15.

"We have a history of leveraging existing technology as demonstrated by the Dnepr missions, and utilizing a commercial capsule simply follows in the pragmatic path we have begun upon," Gold said. "We will soon be moving forward with solicitations focused on the airframe and getting quotes from various subcontractors."

Gold would not say whether Orion prime contractor Lockheed Martin has or will have any involvement in Orion Lite. Lockheed Martin spokeswoman Joan Underwood did not return multiple phone calls seeking comment by press time. But industry and government sources familiar with the effort, said Lockheed has helped Bigelow with the concept.

Low Earth orbit only

From the outside, the full-size mockup built for Bigelow appears to be a clone of NASA's Orion capsule adorned with the Bigelow logo.

But while NASA's Orion is intended to carry up to six people to the International Space Station and four to the Moon, Gold said Bigelow's commercial variant will accommodate a minimum of seven passengers because it is intended for low Earth-orbit missions only. That eliminates the need for bulky propellant tanks, extremely robust heat shields and other lunar-driven requirements that add mass to NASA's Orion design.

"This will be meant for relatively short trips to and back, so there's a difference in hang-time," he said. "It's not intended to operate independently for extended periods, which Orion is."

One of the biggest deviations from NASA's Orion design involves the vehicle's landing system. Whereas NASA plans call for Orion to make an Apollo-style splashdown in the ocean, Bigelow is considering midair retrieval as a safer and more economical means to land the spacecraft following atmospheric re-entry.

"Air-capture is a strategy that has been implemented many times in the past, but never done at weights as high as a capsule," Gold said.

Midair capture was used by the military during World War II to recover gliders and during the 1960s to catch film canisters dropped from Corona spy satellites orbiting overhead.

More recently, NASA attempted a midair capture of a Genesis solar-sample return capsule in 2004, but a parachute failure prevented the awaiting helicopter from making the catch. In 2007, Houston-based Spacehab, now Astrotech, dropped a mockup of a space station cargo module from a helicopter and subsequently recaptured it.

Private space endeavors

While the Bigelow capsule is in the pre-system design review stage, industry sources familiar with the effort say much of the work Lockheed Martin has done on Orion can be readily applied to Orion Lite.

In addition, sources said, Lockheed Martin has a number of preflight Orion capsules planned for testing purposes that could be turned into flight vehicles for Bigelow.

Bigelow is not the only private space company venturing into the realm of manned spaceflight: SpaceX plans to fit at least seven crewmembers aboard its Dragon cargo and crew capsule designed for trips to and from the space station.

Gold said Bigelow wants to see SpaceX succeed with Falcon 9 and Dragon.

"However, we would be foolish to depend completely on one capsule provider or any single launch system," Gold said. "Therefore, it's vital from both a practical and business perspective to ensure that SpaceX and Dragon aren't the only options available to us, hence the need for another capsule."

比格罗公司载人级太空舱正在建造中

新闻发布时间:2010-01-22


  [据美国航天网2010年1月20日报道] 目前比格罗太空公司已经有两个商业空间站原型舱在轨运行,为全尺寸舱体进入太空做好了准备。该公司正在建造两种规格的太空舱模型:能够容纳3人的“日舞”太空舱,和能够容纳6人的、内部容积达到330立方米的BA-330太空舱。
  
  比格罗公司的可扩展舱体设计用来提供可用于出租的低成本商业太空舱,不仅引起私营公司的兴趣,也引起了各国航天局的重视。
  
  2006年7月和2007年6月,比格罗公司先后使用俄罗斯“第聂伯”火箭发射了“起源”-1和“起源”-2两个试验太空舱,它们是载人级“日舞”太空舱和BA-330太空舱的先驱。
  
  比格罗公司目前着眼于2015年发射大型载人空间站进入地球轨道,可能使用“宇宙神”-5火箭或即将开始飞行的“猎鹰”-9火箭。首个比格罗公司空间站全部组件进入太空需要七次火箭飞行。第一个空间站将用于租赁,其中一个舱体将提供给比格罗公司的宇航员使用,他们将对客户的地球轨道设备进行维护。今年比格罗公司还将建造一座A3大楼,这座大楼可以提供近2.5万平方米的面积作为比格罗公司的航天器装配生产线车间。
  
  但比格罗公司2015年的计划还将受到NASA对商业乘员发展(CCDev)计划的影响。2009年比格罗公司曾与波音公司组成团队向NASA提交了一份“商业乘员运输系统”计划。NASA尚没有做出决定。(中国航天工程咨询中心 侯丹 谢慧敏)

NASA管理者讨论Bigelow公司的可膨胀太空舱对接ISS的前景
NASA Managers Discuss Prospect of Bigelow Inflatable on ISS
January 14th, 2011 by Pete Harding  

International Space Station Program (ISSP) managers at NASA’s Johnson Space Center (JSC) in Houston held a two-day meeting this week to discuss the prospect of adding a Bigelow Aerospace inflatable module to the ISS. The Technical Interchange Meeting (TIM) ran on Wednesday 12th and Thursday 13th January.

ISS Inflatable Module:

The purpose of the ISS inflatable module would be a simple, limited capability stowage volume, similar in purpose to the currently on-orbit Japanese Logistics Platform (JLP), which serves as a stowage module for scientific equipment from the Japanese Pressurised Module (JPM) laboratory. The module would be certified to remain on-orbit for two years.

The module would be a collaboration between NASA and Bigelow Aerospace, with NASA HQ providing funding, the ISS National Laboratory Program providing project management, and NASA providing all Government Furnished Equipment (GFE), which includes the Passive Common Berthing Mechanism (PCBM), Flight Releasable Grapple Fixture (FRGF), smoke detector, fan, and emergency lights.

Bigelow would provide the inflatable and inner core structure of the module, and perform all required flight analysis.

“An inflatable module has a rigid center core where the equipment is typically located and where the fabric is stowed for launch. After the module is berthed, it is inflated resulting in a pressurized fabric shell with a cylindrical core structure that houses equipment, etc.” noted L2 info.

In-spite of their soft shell, Bigelow’s inflatable modules are more resistant to Micro Meteoroid Orbital Debris (MMOD) strikes than current metallic-shelled l ISS modules, in part due to Bigelow’s use of multiple layers of Vectran, a material which is twice as strong as Kevlar. In ground tests, MMOD objects that would penetrate ISS modules only penetrated half-way through the skin of Bigelow’s modules.

Click here for ISS news articles: http://www.nasaspaceflight.com/tag/iss/

A proposal for an inflatable module on the ISS was outlined at NASA’s Exploration Enterprise Workshop, which was held in Galveston, TX, in May 2010.

The proposal shows that the inflatable module would be delivered to the ISS in the post-2013 timeframe, launched atop an Expandable Launch Vehicle (ELV) and rendezvoused with the ISS via the currently unfunded Advanced Rendezvous & Docking Vehicle (ARDV).

Given the requirements for three open Common Berthing Mechanism (CBM) ports on ISS for cargo resupply Visiting Vehicles (VVs), and at least two International Docking System Standard (IDSS) ports for crew rotation VVs, it is likely that the Bigelow inflatable module would be berthed to the currently unfunded Node 4.

Also known as the Docking Hub System (DHS), Node 4, like the Bigelow inflatable, would likely be launched on an ELV post-2013 and delivered to the ISS via the ARDV. It would be berthed to the forward CBM port of Node 2. The inflatable module proposal outlined at NASA’s Exploration Enterprise Workshop shows Node 4 with two IDSS ports, and four CBM ports.

The same proposal shows that an inflatable module would be attached to either the Port or Starboard CBM ports of Node 4. At this time, however, no berthing location has been decided for the Bigelow inflatable.

Research into inflatable technologies was listed number three under NASA’s Flagship Technology Demonstration (FTD) program, and funding for such research was proposed in NASA’s 22nd February 2010 budget proposal.

Bigelow Aerospace was founded by Robert Bigelow in 1998. The company is a pioneering world leader in the area of expandable space station modules.

Following the cancellation of NASA’s ISS TransHab inflatable module in 1999 due to budgetary and schedule issues, Bigelow licensed the cancelled TransHab technology from NASA via three Space Act agreements.

Over the next 10 years, Bigelow invested and researched heavily into inflatable technology, with a view to one day making it available to paying customers in the form of an orbital hotel complex. To date, Bigelow has successfully launched two small, uncrewed inflatable demonstration modules – Geneses I in 2006, and Genesis II in 2007.

Both NASA and Bigelow stand to gain from putting an inflatable module on the ISS. Given the fact that inflatable modules could play a major role in any future NASA interplanetary spacecraft or surface base, NASA could gain valuable in-flight data from an inflatable module on ISS, as well as much-needed stowage space.

Bigelow would gain confidence in, and operational experience with, its inflatable modules in a crewed environment, confidence which would undoubtedly also be gained by any potential future customers to Bigelow. Given that the ISS is a permanently crewed operational environment, it is an ideal testbed to demonstrate these technologies.

与太空佛罗里达签署谅解备忘录.
Space Florida and Bigelow Sign Memorandum of Understanding
Source: Space Florida Posted Thursday, February 3, 2011  

MOU to Explore Customers for Orbital Space Complex

CAPE CANAVERAL, FL (February 3, 2011) - Yesterday, Space Florida President Frank DiBello and Robert Bigelow, president of Bigelow Aerospace, signed a Memorandum of Understanding, agreeing to work together to pursue and identify foreign and domestic companies that could benefit from utilization of Bigelow's expandable, orbital space complexes.

Bigelow currently has two pathfinder expandable systems successfully orbiting the Earth, and plans to build the first of multiple fully-functioning stations by 2015. The initial "Alpha" complex will be comprised of Bigelow's patented "Sundancer" and "BA 330" modules, which are significantly larger than current modules aboard the International Space Station. Additionally, customer launch and lease rates for the facilities are expected to be extremely cost-efficient for domestic and international customers. Bigelow is marketing eighteen (18) separate human space flight programs with a variety of duration and pricing options, including an option of $28,750,000 for a 30-day astronaut visit.

According to Bigelow, if the company attracts enough customers to lease all of the orbiting, inflatable modules on Complex Alpha, it could mean up to 25 launches a year - possibly from Cape Canaveral - to ferry cargo and crew. Module launches could be accommodated by current United Launch Alliance Atlas V rockets or other vendors.

"Space Florida continues to pursue a number of diverse strategies to propel the growth of the space industry in Florida," said Space Florida President Frank DiBello. "Bigelow has developed an orbital work environment that has substantial commercial applications. Our goal through this partnership will be not only to establish a significant Bigelow presence in Florida, but also to leverage both companies' relationships to attract new, internationally-based customers for the orbiting complex."

"Bigelow Aerospace ambitions are to launch and successfully operate as many commercial modules as possible," said Bigelow President Robert Bigelow. "None of the large BA 2100 or 3300 modules and station complexes can be transported by land or launched with a VTOL (vertical take-off and landing) vehicle for the foreseeable future. Accordingly, Bigelow Aerospace is looking for manufacturing facilities in close proximately to launch sites and launch companies capable of high volume traffic, locations like Cape Canaveral and companies like ULA."

It is intended that this innovative partnership will help build a dynamic future for on-orbit commercial space operations, enhancing overall launch activity, employment, and growth of the aerospace field in Florida.

This collaborative business development partnership will also explore approaches to supporting 1/3 scale models of the orbiting outposts in Florida. These models would assist in marketing to new customers as well as simulation of customer requirements and concepts of operations for payloads, prior to flight.

About Space Florida: Space Florida was created to strengthen Florida's position as the global leader in aerospace research, investment, exploration and commerce. As Florida's aerospace development organization, we are committed to attracting and expanding the next generation of space industry businesses. With its highly trained workforce, proven infrastructure and unparalleled record of achievement, Florida is the ideal location for aerospace businesses to thrive - and Space Florida is the perfect partner to help them succeed. www.spaceflorida.gov.

Bigelow完成生命支持系统的初始测试
Bigelow Completes Initial Test on Life Support System
May 6, 2011, at 2:00 pmin

Bigelow Aerospace completed an initial closed-loop test in March of a prototype environmental control and life support (ECLS) system designed to support extended crew stays inside the inflatable habitats the company is building to provide research facilities and hotel accommodations in space.

The March 31 demonstration was conducted inside the company’s North Las Vegas headquarters in a newly constructed test chamber, according to Eric Haakonstad, Bigelow Aerospace chief engineer. He said the test involved locking three Bigelow engineers inside the 180-cubic-meter structure for about eight hours, during which they performed a variety of tasks that demonstrated the ECLS system’s ability to control temperature, humidity, pressure, oxygen content and the removal of carbon dioxide and trace-gas contaminants from the environment.

“Eight hours is a convenient steppingstone for us,” Haakonstad said in an April 4 interview. “It’s enough time to get to steady-state conditions but not necessarily long enough where we have to worry about — we’ll call it overnight hygiene and sleeping arrangements.”

Haakonstad said the test chamber is designed to replicate the interior volume and shape of the three-person Sundancer inflatable module the company is building, though he said the facility is scalable to the larger BA-330 module. The BA-330 is designed to offer 330 cubic meters of internal volume for a crew of six.
