Bosch jet thruster blasts your motorcycle out of a skid
Modern motorcycles have gained safety features like antilock brakes and even (experimental) self-balancing, but riders still highly exposed in crashes. Bosch is trying to stop accidents in the first place in a crazy new way: using jet thrusters. Let's say you've leaned into a steep curve, hit a patch of gravel or sand and started to slide in an unrecoverable way. A sensor will detect the wheel slip and fire gas from an airbag-type accumulator out of a tank side nozzle, creating a reverse thrust that miraculously rights your motorcycle.
ESA's air-breathing thrusters help keep satellites alive longer
Satellites could soon remain in orbit for years on end thanks to new technology that turns air molecules into propellant. A European Space Agency (ESA) team has developed an electric thruster that collects molecules from the top of the atmosphere and gives them electric charges so they can be accelerated and ejected to provide thrust. This could create a new class of satellites able to operate in orbit for long stretches.
NASA successfully tests microwave thruster, paving the way for speedier space travel
As with airplanes and many other self-powered machines, the fuel a shuttle engine requires can weigh nearly as much as the object it's propelling, increasing costs while significantly limiting range. It's a challenge we're going to need to overcome before launching long-distance treks through space, where carrying enough fuel may not currently be possible. One proposed method for getting future spacecrafts to their destinations is by utilizing a device called a microwave thruster. A British scientist named Roger Shawyer managed to build a similar engine called an EmDrive several years ago, and while a Chinese team also accomplished the same, the rest of the world hasn't paid much attention until NASA confirmed from its own research that such a device could work during a presentation earlier this week.
ViaSat-1 moves into fixed orbit, aims its broadband ray gun
To advanced aliens and Europeans, ViaSat-1 is no big deal. To Americans and Canadians, however, it's their ticket to more affordable satellite broadband coverage at speeds of up to 10Mbps, as well better in-flight connectivity. The satellite's plasma thrusters have moved it into geosynchronous orbit and its payload has been switched on, so the initial service is on track to begin by Christmas time, with further services in 2012. Want to know more about the tech involved in such extraterrestrial feats? Then look for the detailed PR after the break.
Amazon CEO's flying water tank crashes, leaves dent in his space travel dream
In a moment of profound candidness, Amazon billionaire Jeff Bezos has revealed that the mid-air failure of his unmanned spaceship 11 days ago was "not the outcome any of us wanted." The searing truth of his statement is certainly borne out by the fact that NASA has poured millions of dollars of funding into Bezos's space company, Blue Origin, in the hope that it will one day ferry people to the ISS and replace the scuttled shuttle program. Indeed, Blue Origin's latest craft looked every inch a shuttle-beater until it suddenly went berserk at 45,000 feet, forcing the Asimovian onboard computer to cut power and nose dive into the ground in an effort to avoid civilian casualties. Not an ideal result, to be sure, but Jeff is hardly likely to give up on his starry ambitions -- everybody knows he has a thing for thrusters.
