Virgin Galactic's SpaceShipTwo completes first flight with crew on board
It still has a few more key hurdles to cross, but it looks like Virgin Galactic's SpaceShipTwo (a.k.a. the VSS Enterprise) is remaining on track for its first commercial flight sometime next year. The latest milestone is the spacecraft's first flight with a crew on board, which occurred on July 15th at Virgin Galactic's usual base of operations, the Mojave Air and Space Port. As with previous flights, however, SpaceShipTwo remained attached to the VMS Eve "mothership" for the duration of the flight, but it did stay aloft for more than six hours as the crew (including test pilots Peter Siebold, Michael Alsbury) went through a range of tests. Still no word on exactly when SpaceShipTwo will see its first solo flight but, barring any change in plans, that should be the next flight that takes place.
IKAROS gets first burst of solar propulsion, wants more
Photons, man, it's all about the photons. Japan's solar sail-equipped IKAROS probe has recorded its first propulsion derived from the force of sunlight rays hitting its tender surface. The force generated is a truly minuscule 1.12 millinewtons, but that can go a long way (literally) in a frictionless environment like space. The kite's sails also soak up Sol's emitted light to generate electricity, making the most out of the one resource available to it. So now that we've figured out how to do all that, shall we get started on colonizing Mars or what?
IKAROS successfully stretches wings, prepares for solar spaceflight
Though it may look like a collection of tinfoil and string, the photo above depicts what may be the first solar sail to actually propel a spacecraft. Japan's IKAROS (Interplanetary Kite-Craft Accelerated by Radiation of the Sun) just unfurled the 7.5 micron (.0003-inch) thick polyimide membrane 7.4 million kilometers from Earth this week, and expect its embedded thin-film solar panels to propel the craft past Venus and towards the dark side of the sun. Because wax and feathers only get you so far.
520-day simulated mission to Mars underway in Russia
Last Thursday, a six person mission to Mars began in Russia -- except that the crew isn't going anywhere. The would-be astronauts (including Russian, French, Italian and Chinese members) have agreed to undergo a 520-day long simulation trip to Mars, which includes a 250-day flight to the planet, a 30-day exploration, and a 230-day return trip, all in the name of preparation and research. This is not the first time that Russia's undertaken long-term simulations -- last year six hopefuls participated in a 105-day long experiment -- hoping to gain insight into the long-term effects such isolation can be expected to produce. They won't be weightless, but many of the other conditions will be as realistic as possible -- including communications time delays, wonky internet, and one shower every ten days. Sounds a lot like blogging to us. We wish them luck -- check out the video below.
Boeing X-37B autonomous space shuttle launched last night, due back 'whenevs'
Boeing's X-37B, the test craft that's been kicking around for the last decade or so, has finally made it into orbit. Formerly a NASA project, we've heard little about the thing since it passed into DARPA hands in 2004 -- and statements like those of the Air Force's Gary Payton don't help much: "in all honesty, we don't know when it's coming back for sure." How's that for autonomous? Also uncommented upon, yet tantalizing, are the military's intentions for the unmanned vehicle, which can remain in orbit 270 days at a time. Spy drone? Orbital weapons platform? Plaything for our future robot overlords? (Let's hope it's not the last one.) The success of the mission will depend on a couple things, namely: how the return trip goes (it should make it back to California's Vandenberg Air Force Base via autopilot... sometime) and whether the thing can be re-launched quickly enough. Ideally, the craft should be ready for another flight in fifteen days. Another test is planned for 2011. [Thanks, One Love!]
Tiny, robotic space shuttle to be launched into orbit in April
A long-delayed project initiated by NASA and carried out by Boeing may finally get to see the light of cold, beautiful day according to reports from the US Air Force. The X-37, a small, robotic space plane is set to make its first unmanned trip into orbit in April. Conceived by NASA as an unmanned re-entry lifeboat for crew of the International Space Station, the X-37 reportedly has a cargo bay of just 7 x 4 feet, and it has apparently been shipped to Florida for its maiden voyage, where it will be mounted to an Atlas V rocket for its launch into space. There aren't any other details -- the people running the project are keeping everything pretty quiet, but the shuttle itself is reported to have said that it's putting itself "to the fullest possible use," adding that that "is all I think that any conscious entity can ever hope to do."
Space Adventures offering $100 million trip to space
While there's long since been ways to get a piece of your mind (or your best Photoshop effort) launched into space, getting your person up there isn't exactly feasible if your pay stub isn't stamped by NASA. Now, however, Space Adventures is looking to hoist a pair of untrained civilians into space in 2008 and 2009 aboard a Soyuz craft, and the firm will soon be selling seats for the low, low price of $100 million apiece. The Lunar Mission will eventually bring you "to the other side of the moon," and while we're sure the itinerary is quite detailed considering the price of admission, the firm isn't dolling out too much more until you prove your bank account is stocking the required dough.[Thanks, Yossi]
Space contests take flight, IRS takes notice
It looks like we're in the midst of a space race of a different sort, with no less than three recent contests promising to take would-be space cadets into varying degrees of orbit for free, although it seems that the winners may be in for more than a case of space sickness. Our cautionary tale comes courtesy of Oracle and Space Adventures, who awarded a suborbital spaceflight to one lucky winner, Brian Emmett, only to have him find out he'd have to pay taxes on the $138,000 value of the round-trip flight, forcing him to give up his seat in favor of someone with deeper pockets. While its potential tax burden is unclear, Microsoft is forging ahead with its "Vanishing Point" space contest, set to announce the winner tomorrow, who'll also get a taste of some suborbital action. Those looking to hitch a ride on the cheap aren't entirely out of luck just yet, however, with New Scientist and Audi today announcing their own contest that'll run through April 30th. To enter, you just have to tell 'em what you think is the world's best patented invention, with one lucky winner set to be shot 62 miles above the Earth, decked out in their own personalized suborbital flight suit no less. Those of us on this side of the pond are unfortunately out of luck on this one though, with the contest strictly for U.K. residents only.Read - Space.com, "No Free Ride to Space for Contest Winners"Read - The Register, "Microsoft prepares to shoot geek into space"Read - New Scientist's "Win a trip into space"[Thanks, Matt]
Stephen Hawking in space (space... space...)
Well-known theoretical physicist and all-around geek hero Stephen Hawking has told the press he plans to undertake a zero-gravity flight this year in preparation for a hopeful berth on Richard Branson's Virgin Galactic space tourist service when it launches in 2009. Hawking, who has the neurological disease amyotrophic lateral sclerosis, communicates via a blink-controlled computer and uses a high-tech wheelchair for mobility, making space flight somewhat challenging -- but Virgin Galactic spokesperson Stephen Attenborough said in a statement Monday that Branson is committed to working through the issues that need to be addressed in order to accomodate people with disabilities on his company's trips into suborbit. Cost of a two-hour suborbital spaceflight? $200,000. The look on the most famous cosmologist's face upon actually making it into space? Priceless.
