| Giant nets could remove orbiting space junk |

Star Inc. president Jerome Pearson was one of the early pioneers of space elevators; in 1975, Pearson wrote a paper on the subject that inspired Arthur C. Clarke’s description of a space elevator in his popular science fiction book The Fountains of Paradise. Consisting of a long cable of nanomaterials, a space elevator would stretch from Earth to a point in geostationary orbit about 22,000 miles above the surface, carrying people and objects into space on its shuttles. |
A dozen space vehicles, equipped with 200 nets each, could scoop up the space debris floating in low Earth orbit, clearing the way for a future space elevator. That’s the idea described last Friday at the annual Space Elevator conference by Star Inc., a company that is receiving funding for the project from DARPA.

NASA Image Of The Day
| Panorama of the East Coast | ||
| This Jan. 29 panorama of much of the East Coast, photographed by one of the Expedition 30 crew members aboard the International Space Station, provides a look generally northeastward: Philadelphia-New York City-Boston corridor (bottom-center); western Lake Ontario shoreline with Toronto (left edge); Montreal (near center). An optical illusion in the photo makes the atmospheric limb and light activity from Aurora Borealis appear "intertwined." Image Credit: NASA... | ||
