Intermetallic materials are different than alloys in that they are combined at the molecular level, as opposed to merely melting down metals and creating a homogeneous mix. Scientists want to manufacture Titanium Aluminide up in space because on Earth, the difference in the metals' weight prevents the alloys from diffusing correctly. The ESA currently plans to go up to the International Space Station to conduct tests on the manufacturing process. [BBC via io9 via DViCE]

<![CDATA[ Space Is Full of Crap ]]> The European Space Agency has just released images showing all the satellites and human-made debris now orbiting space as a result of 51 years of launching stuff since Sputnik. That's about 6,000 satellites up there—of which only 800 remain operational—plus thousands of other objects from launches and accidents. According to their mindblowing simulations things are getting a lot worse:

About 50 percent of all trackable objects are due to in-orbit explosion events (about 200) or collision events (less than 10).

Yes, we knew that there was a lot of crap out there, but not to this extent. According to the ESA, this is really bad news and urgent measures are needed. Explosions in space are not disastrous on their own, but because of the aftermath. One example: a geostationary satellite travels at 6,213 miles per hour. If it explodes, all the debris stays near the orbit, forming a cloud around the Earth within a few days, as this simulation shows:

The ESA is urging to introduce measures to mitigate this problem, like the complete depletion of fuel in rocket stages (like some Delta launchers already do following NASA's Procedural Requirements for Limiting Orbital Debris) or returning objects to Earth once their mission is complete (perhaps to destroy them on re-entry,) just like SES Americom is going to do with their brand-new AMC-14. This satellite failed to reach its projected altitude and now has to be splashed into the sea because of a dispute with Boeing, which won't let SES Americom use their patented recovery method to put the satellite into the right geostationary orbit.

The impact of these measures could be huge, as reflected by this simulation of how things could look by the year 2112, with and without taking action:

While the idea of bringing back used stages and satellites back to Earth may seem too expensive, in the long run it's clear that leaving all this trash up there is going to have huge consequences to the development of space exploration and colonization. Those concepts may still seem science fiction for many, but as these simulations show, the current and future problem is very real, and could be extremely dangerous.

<![CDATA[ ESA's Autonomous Space Truck Blasts Off Tomorrow ]]> The European Space Agency is launching the first Automated Transfer Vehicle tomorrow in French Guyana. Though it looks like a satellite, the ATV, christened Jules Verne, is really an unmanned cargo-hauling robot capable of carting 7.6 tons of supplies and other astro-crap up from Earth, and even tow the International Space Station itself to a higher orbit. And it'll do a lot of this stuff with no guidance from the carbon units:

The most notable is the ATV's automatic rendezvous and docking technology - the ship can find its own way to the station and attach itself without any human intervention.
Other vehicles are manually driven in—optical sensors on the ATV steer and line up the truck for docking, as you can see in the images below (taken from the amazing BBC News video you can jump to below). Yes, the ESA refers to this automated linkup of ATV and ISS as "mating." ATV_Docking.jpgNote to self: Space stations are not safe hideouts during robot revolts.

Tomorrow's launch will be carried off by an Ariane 5 rocket, and the double-decker-bus-sized ATV will be the heaviest payload ever carried by one. The maneuver will be trickier than usual, with the upper stage of the rocket igniting twice, to get it up there and then again to boost it safely over the Pacific Ocean. ATV_Diagram.jpg[BBC News]

<![CDATA[ ESA To Debut Satellite-Based Multimedia Radio ]]> Radio listeners in Europe may need to thank the European Space Agency if all goes according to plan. The ESA is set to debut a new type of multimedia radio tomorrow that makes use of currently existing satellites and a low profile antenna affixed to cars' roofs (seen here). The new and improved (!) radio is being designed in order to eliminate many of the problems associated with radio today, like static, signal loss in tunnels and the like. These new radio will also cache all content onto a hard drive (or flash drive), so that listeners can go back to listen to something over and over again. (Incidentally, isn't that the reason why the RIAA is suing XM?)

No commercial plans have been announced thus far as this is more of a proof of concept more than anything else. Interesting development and good to see the ESA devoting resources to improve the signal quality of breakfast radio. Come back when you've put a man on the moon.

<![CDATA[ Firefighter Suit Chock-Full of Tech ]]> igarment.jpgThe I-Garment (Integration System for Management of Civil Protection Units) promises to make the dangerous job of firefighting markedly less so. Designed by a consortium of Portuguese firms and agencies and funded by the European Space Agency, the I-Garment makes use of numerous technologies, including satellite communications and WiFi. Satellite usage would be beneficial in more remote locations, as local communications infrastructure often becomes damaged during quickly-moving fires. Sensors inside the suit monitor the wearer s vital signs, a potentially life-saving feature sure to appear in future emergency response personnel s suits.

<![CDATA[ Today In Robotics ]]> Fold-Up Unmanned Vehicles, Biomedical Micro-Robot, The Weird-7 DIY, and ESA's Mars Rover...

Following-up on Monday's Gizmodo Ink, The National Forest Service in Utah is testing a fleet of robotic fire-fighting planes. "Some of the aircrafts can be carried in a backpack, unfolded, then dispatched day or night to spy on a fire." They are also equipped with cameras and infrared night vision (the benefit of flying by night is that these bots would not interfere with the manned planes that drop fire retardant). The planes communicate with one another and beam back real-time monitoring of the fire's spread.

These planes have a wingspan of 5 feet, weigh only 15 pounds, and can fly for up to six hours. An experiment with larger drones will begin next spring in California.

A team of scientists from the Swiss Federal Institute of Technology in Zurich, Switzerland have successfully tested a microscopic robot that could be injected into the human body with a syringe. Unlike other micro-surgical robotic creations, this one is not battery or electric cable powered. Instead, the bot is guided by an external magnetic field. The minimally invasive robot, which is about four hair-widths long, was successfully demonstrated using a watery maze but would eventually be targeted to blood vessels in the heart, eyes and ears.

"The application we're actively considering is eye surgery in which these devices are guided inside the eye toward the retina by a surgeon to inject drugs in retinal veins that are about the size of a human hair," said team leader Brad Nelson, professor of robotics and intelligent systems.

The European Space Agency has scrapped the mission plan from the team behind Beagle 2 and is now pinning its Mars aspirations on a single rover robot. The craft is scheduled to blast off in June 2011, and reach Mars in June 2013.
