Will the Japanese be the first to elevate to space?

One of the most promising technologies for the aspiring outer-space commuter is the space elevator. The concept, like quite a few others, was pressed into the public imagination by Arthur C. Clarke, who in his 1979 novel The Fountains of Paradise described a incredibly thin, incredibly strong carbon filament with one end anchored on Earth and the other extending up to a satellite in geostationary orbit. Now, a group of Japanese scientists are convinced that they can build a space elevator more quickly and cheaply than has been believed possible.

15 industrial-design graduate students dream and design big for NASA

“Design for extreme environments” sounds like a new cable show, but it’s actually a class at RISD that focuses on building habitats for truly challenging locations—like the moon. Last fall, NASA asked the students to design a mobile dwelling for its next manned mission to the moon, scheduled for 2020. “NASA wanted a rover that could house four people for two weeks in 24-hour sunlight,” says student Zack Kamen.

Scientists envision ‘bots working intelligently while exploring distant worlds

EVE, otherwise known as the Extra-terrestrial Vegetation Evaluator, represents an intelligent probe sent to an abandoned Earth in the film “WALL-E.”

A spaceship descends with a thunderous roar and deposits a futuristic probe before taking off again. The Extraterrestrial Vegetation Evaluator (EVE) soon activates and begins flying around, scanning the barren surface for signs of life.

KITCHEN SINK HELIOSPHERE: If the solar wind is like a stream of water spreading out on a flat sink bottom, then the boundary where the flow breaks against onrushing soapy water (interstellar gas) is the termination shock (recently encountered by the spacecraft Voyager 2) and the region of slower-moving water beyond it is the heliosheath.

Hurtling through space 31 years after its launch, the Voyager 2 spacecraft has sent back the most detailed view yet of the shock wave that marks the thinning of the solar wind, the charged particles streaming from the sun.

Researchers say the crossing confirms that the heliosphere—the region swept out by the solar wind—is actually lopsided, perhaps due to a tilted magnetic field in local interstellar space.

The shock wave, or heliospheric termination shock, occurs when the supersonic wind thins to the point that it can no longer rebuff the denser haze of charged particles flowing through interstellar space. Instead, the solar wind suddenly collapses in on itself.

A growing cloud of trash threatens space tourism and has experts scrambling to clear the mess

Robots could gain momentum to change orbit by swinging weighted tethers like a discus thrower does. This would move them to large pieces of old debris, to which they would attach Terminator Tethers

Along with satellites and space stations, Earth is surrounded by tens of millions of pieces of floating space debris. Like any landfill, the trash is diverse, ranging from dead satellites to castaway rocket parts to flecks of paint. On average, over the past 40 years, one piece of space junk has fallen to Earth every day.
