Japan sends Kounotori 2 spacecraft on suicide mission to study re-entry process
An unmanned cargo ship built by the Japan Aerospace Exploration Agency (JAXA) is set to go up in flames tomorrow in the name of interplanetary research. Along with a load of space station junk, the Kounotori 2 spacecraft is packing something akin to a black box, also known as a Re-entry Breakup Recorder (REBR), that will collect and transmit data about the ship's final moments. The space station's crew will activate the REBR before Kounotori 2 begins its final assignment. As soon as it starts showing signs of re-entry, the sensor will begin to collect data including temperature, acceleration, and rotation rate, and will then break away from the craft for a final free fall to Earth, at which point the REBR will dump its findings. Scientist hope the device will help answer questions about exactly what happens when things fall apart during re-entry. If all goes according to plan, the REBR will plunk down in the ocean sometime later, but its host will never be seen again... farewell, Kounotori 2.
Handheld millimeter / microwave camera to see through walls, your underpants (video)
You know those scanners that peep your naughty bits at the airport? Well, a team of researchers have been working on a handheld camera that sports the same technology, and while they're touting its future impact on stuff like cancer detection and aerospace engineering, we can't help but squirm thinking about its Peeping-Tom potential. The camera currently takes 30 images per second by transmitting millimeter and microwaves to a "collector" on the other side of a subject, and then sends them to a laptop for real-time inspection. Aside from being able to see straight through your BVDs, it can also be used to detect defects in spacecraft insulation, find termites lurking in the walls of your apartment, and help in the diagnosis of skin disease. The camera's creators are working on a smaller, one-sided version of the device that could have mass-market appeal -- we just hope this thing stays in R&D long enough for us to get our bikini bodies back. Check out a video of its G-rated abilities after the break.
Japan sends a ribbon into space, asks it to test the magnetic currents
Tether propulsion seems to be the OLED of the spacefaring world, carrying as it does a lot of promise but seemingly never ready for the big time. The fundamental premise is as simple as it is appealing -- a long strip of metal stretched out in space can theoretically exploit the Earth's magnetic field to maneuver itself without expending any fuel of its own. This is done by sucking up ionospheric electrons at one end and, predictably enough, spitting them out at the other, allowing current to flow through the tether. Japan's aerospace agency has recently shot off a testing vehicle for just this theory, a 300 meter-long, 2.5cm-wide ribbon, which has managed to successfully generate a current. No thrust-measuring equipment was on board and it's still very early days, but hey, there's at least the chance that one day satellites will all sprout long, elegant tails to power their way through the sky... and into our private lives.
Deadly blast rocks Virgin Galactic rocket test
This week is quickly becoming a tough one for the aerospace industry, as just a day after NASA reported tampering on an ISS bound computer, an explosion at the Mojave Air and Space Port has claimed two lives and seriously injured four others. The blast reportedly occurred during a "test of a new rocket motor for SpaceShipTwo -- a spaceship being built for Virgin Galactic, Richard Branson's space tourism company." According to a spokeswoman for the spaceport, the blast was "on a remote pad" at an airport home to Scaled Composite (which is the builder of the first private manned rocket to reach space), but the firm's founder Burt Rutan wasn't in attendance when the "cold fire test" went awry.
Plaster Georgia Tech / MIT's unmanned spacecraft with logos, text
If there's anything left to accomplish after creating autonomous UAVs and cramming optical circuitry on a silicon chip, it's allowing tax paying citizens to pen their thoughts on an unmanned spacecraft. In a joint initiative between Georgia Tech and MIT, the Your Name Into Space project aims to launch a small research satellite in 2010 into Earth's orbit, and the technology on board will purportedly "help pave the way for humankind to explore our solar system." Folks who throw their name, slogan, logo, or snarky catchphrases onto the craft can expect photographs of their adornment "with the Earth in the background" while it's orbiting space, and if your piece of textual glory lands on a segment that will be returning to Earth, it's all yours upon landing. So if you're looking to splurge a little this year on a bit of tax deductible fun, you can put nearly anything on this forthcoming machine for $35 to $250 per square centimeter, depending on location.[Via MAKE]
