PASADENA, Calif. -- Engineers from NASA's Jet Propulsion Laboratory and students at the California Institute of Technology have designed and tested a versatile, low-mass robot that can rappel off cliffs, travel nimbly over steep and rocky terrain, and explore deep craters. This prototype rover, called Axel, might help future robotic spacecraft better explore and investigate foreign worlds such as Mars. On Earth, Axel might assist in search-and-rescue operations.
Mirrors are a critical part of any space telescope, and the James Webb Space Telescope's mirrors are made of a special element that will enable it to withstand the rigors of space and see farther back in time/distance than any other telescope now in operation. Space telescope mirrors must endure the extremely frigid temperatures in space, be highly reflective, lightweight and tough. Those are exactly the qualities that make up the 18 mirrors being developed for the Webb Telescope.

The prototype department of Material Beliefs is proposing to expand the growing do-list of household robots by including household pest eradication. While sharing some of the same vibe as your typical bug zapper, these devices are designed to provide both functional removal of pesky nuisances right along with a form worthy of interior spaces. On top of that, these concept machines can provide both conversation ideas and hours of viewing pleasure while entrapping and devouring their prey.
Inspectorbots go beyond your typical RC chassis to conquer applications including security surveillance, building inspections, and the like. Several different models are offered to do everything from toting around a tiny wireless camera to carrying a human...
Reader Doug Emes sent us a link to the Guy Robots website which contains a gallery of art robots built from industrial surplus and salvaged parts. Intrigued, I contacted Rich Muller, the artist, to find out a little more. He writes,
I work in the aerospace industry in Los Angeles, and I've been making robots for a few years. Los Angeles is a good place for finding raw material, there are flea markets, swap meets, and countless garage sales every weekend. There are also a number of surplus stores that sell old electronic and avionic equipment, not surprising considering the large amount of aerospace industry in Los Angeles. The old material gets sold to small businesses and garage tinkerers setting up laboratories as well as Hollywood set-decorators and artists. A favorite place is Apex Electronics, where you can find anything from bakelite knobs to a rocket nose-cone. I build and photograph the robots, and my brother, Eric, comes up with the names and bios.
When the article hit in February describing the collision of Russian and US space satellites, I was both surprised and suspicious. The satellites shared a popular near-Earth orbit at around 500 miles, but still, it's like having two grains of sand meet in a football stadium. Not impossible, but very unlikely, especially since these multi-million-dollar satellites are tracked by several Earth-based stations. The position of nearly 1000 satellites are monitored along with thousands of tiny items - some as small as 5cm. Now, a Russian General is saying the collision might have been a military test to prove if a robotic satellite could be capable of disabling or destroying an enemy satellite. Whether any of this is true or not remains to be seen, but I don't think we've heard the end of this story.
