Can Space Travel Be Environmentally Friendly?

Richard Branson and Virgin Galactic aim to make it so

Space will be the final frontier for tourists if Sir Richard Branson has his way.

Getting there won't be easy on the wallet—but it won't be so hard on the planet, either, contends the British adventurer and Virgin Group founder, who touched down at Washington's National Press Club recently.

"Very environmentally friendly," Branson said. "The [carbon] cost of us putting someone into space will be less than flying to London and back on a commercial plane."

Five years and $150 million into his Virgin Galactic venture, Branson has a bona fide spaceship to show for it.

Over the past few months, pilots have conducted several test flights of the space-launch vehicle Eve. The mother ship—named after the billionaire's mum—is designed to ferry SpaceShipTwo and its two pilots and six astronauts more than 50,000 feet above the Earth's surface.

From the stratosphere, SpaceShipTwo would blast to a suborbital altitude of about 360,000 feet using hybrid rockets.

A "whole new era of space travel" may be nigh, boasted Branson, who plans to go boldly where just a few tourists have gone before. SpaceShipTwo is slated for completion by the end of the year, he said, followed by about 18 months of testing.

Scientists James Lovelock and Stephen Hawking are among 300 passengers queued up to ride in Branson's spacecraft. Contrary to rumors, "Star Trek" alumnus William Shatner is not among them, Virgin Galactic President Will Whitehorn said in an interview.

A ticket to ride is $200,000—perhaps chump change for Branson but a king's ransom for the rest of us. It is the "trip of a lifetime," Virgin Galactic's online portal promises.

"Reserve your place in space now and look forward to three days of training in preparation with your crew," the sales pitch continues. "Traveling at over three times the speed of sound to a distance of around 360,000 feet above the Earth's surface, experience weightlessness and enjoy the breathtaking view."

Shortly before SpaceShipTwo reaches the apogee of its flight path, the vessel would fold its wings for re-entry through the upper atmosphere. The ship's wings would flatten out once more at 60,000 feet in order to glide back to terra firma.

Eye on emissions, fuel savings

Virgin Galactic uses a landing strip in California's Mojave Desert now, but construction crews plan to break ground next month on a state-of-the-art "spaceport" near Truth or Consequences, N.M.

"Spaceport America," a $198 million project funded by the state, will feature a vertical launch pad and a horizontal runway, according to project officials. Virgin Galactic's fellow tenants will include UP Aerospace Inc. and Lockheed Martin Corp.

The project's terminal and hangar facility, designed by URS Corp. and Foster + Partners, will feature solar-thermal panels. A passive cooling system will draw in hot air from the outside and chill it through a series of concrete tubes.

Virgin Galactic's spacecraft were also designed with environmental sustainability in mind, Whitehorn said.

Mother ship Eve's jet engines will run on kerosene initially but are also capable of running on butanol, a biofuel that can be made from algae. SpaceShipTwo's rockets will burn nitrous oxide —but only briefly—as the spaceship would require no fuel for takeoff, reentry and landing.

According to Whitehorn's calculations,

carbon dioxide emissions per passenger on a Virgin Galactic spaceflight would be about 60 percent of a passenger's carbon footprint on a round-trip flight between New York and London. About 70 percent of a spaceflight's CO2 emissions would come from mother ship Eve, which must carry SpaceShipTwo into the stratosphere.

    You can't call something "green" just because it has less of a carbon footprint than a round trip flight to another continent! "Hey my H2 gets great gas mileage! Very good on the planet. Just compare it to the standard hummer if you don't believe me."

    They mention that space is the last fronteir for tourists but I've heard on countless occations that we know more about the dark side of the moon and Mars than we do about our own oceans floor. So that makes me wonder if the bottom of our oceans will ever become a tourist hotspot.

    Hey Jokesterpants - There is no "dark side of the moon."

    There is a FARSIDE!! Maybe you shouldn't be writing to a science magazine.

    There is a FAR SIDE. Maybe you should NOT be writing to a science magazine at all.

    $200,000 for a "class A" amusement ride to the edge of space and it's green! HOW FREAKING WONDERFULL.
    What a pile of PR crap. and after they kill a couple of tourists all none government space flight will be outlawed.
    If Branson wanted a safe true space drive he would back development of an EMF (electro motive force) drive system.

    What a ridiculous program! Space travel being leveraged as entertainment before exploration?

    Hey Branson, you might want to go read a certain book with a character called John Hammond. You two seem like a perfect match.

    In spite of Jokesterpants's mistake, he makes an excellent point. And PeterT, if you can't figure out how to use the message board without posting the same message twice, maybe YOU shouldn't be writing here.

    vogtr, "green" technologies are used, it is a relative measure. Everything affects the biosphere in some manner, even if we would sit around doing nothing.

    It is an awful term btw, Earth and its biosphere is "a pale blue dot". I think Virgin may demonstrate just that, combining the true color of a live world with the tangible finiteness of Earth, which will take some of the subjectivity and woo out of environmental businesses.

    "So that makes me wonder if the bottom of our oceans will ever become a tourist hotspot."

    I'm sure people are working on that, I seem to remember tourist subs. But space seem to attract more people and capital than the down to (and under) Earth businesses of deep diving and spelunking.

    look at it this way: every answer to every environmental and energy issue we face today lies Out There. if Branson gets this right, we may well see a boom in private and commercial space development in a fashion similar to (and not seen since) the aviation boom of the 1920s and 1930s. the future has to start *somewhen*.

    Space travel can certainly become "more" environmentally friendly, but it will never be as environmentally friendly as simply not engaging in it at all. Not that I'm saying we should stop exploring - but exploration is inherently unnecessary and therefore not "green". http://www.canspace.ca
