Prepare for a hotel in space

An experimental inflatable spacecraft bankrolled by real estate magnate Robert Bigelow rocketed into orbit yesterday to test technology that could be used to fulfil his dream of building a commercial space station.
The Genesis I satellite flew aboard a converted Cold War ballistic missile from Russia’s southern Ural Mountains. It was boosted about 500 kilometres above Earth minutes after launch, according to the Russian Strategic Missile Forces.
The launch was a first for the startup Bigelow Aerospace, founded by Bigelow, owner of the Budget Suites of America hotel chain. Bigelow is one of several entrepreneurs trying to break into the fledging manned commercial spaceflight business.
Despite the successful launch, significant hurdles still remain.
Mission controllers were awaiting word of the spacecraft’s health. Once that’s confirmed, it will begin the tricky job of ballooning itself to twice its pre-launch width in a process that could last several hours.
Bigelow hopes to use inflation technology to build an expandable orbital outpost made up of several Genesis-like modules strung together like sausage links that could serve as a space hotel, science lab or even a sports arena.
“We’re ecstatic. We’re just elated,” Bigelow said from Las Vegas. “We have a sense of being on a great adventure.”
Bigelow has committed $500 million US toward building a commercial space station by 2015. So far, $75 million has been spent on the project.
Because yesterday’s unmanned mission was experimental, Bigelow said he was prepared for problems.
“I wouldn’t be the least bit surprised if we have a number of different systems fail,” he said on the eve of the launch. “I would hope that we have some success.”
The watermelon-shaped Genesis I is a one-third scale prototype of the commercial space station to which the company eventually hopes to fly humans.
Unlike the rigid aluminum international space station, Genesis I consists of a flexible outer shell and is layered with tough material such as Kevlar, which is found in bulletproof police vests, to withstand flying space debris.
The 1,300-kilogram Genesis I measured 4.2 metres long and 1.2 metres wide at launch and was to inflate to twice that width in orbit. It carried photos of Bigelow employees and insects that scientists hope to study to determine how well they survive the flight.
Equipped with a dozen cameras to be aimed at the Earth, the spacecraft will circle the planet for at least five years while scientists study its durability.
Bigelow Aerospace plans to launch several prototypes this decade. Future missions will test docking among spacecraft, but the maiden Genesis flight will primarily focus on the inflation process.
In the 1990s, NASA studied inflatable technology for a possible trip to Mars, but later dropped the idea after deciding inflatable modules were too expensive. Bigelow Aerospace then licensed the technology from NASA.
This fall, the company hopes to launch Genesis II. Over the next several years, the company plans to test larger prototype spacecraft, including a full-scale mock-up slated to launch in 2012.
