Gravitational Tractor

Post by Christopher K. » July 7th, 2012, 10:04 pm

Many people think about where or when an asteroid may hit the Earth. In the fall of 2005 Edward Lu and Stanley Love (then NASA astronauts) developed an idea wherein a spacecraft would "use gravity as a towline". The idea rests on the assumption that the human race would have several years of notice--and we probably would--if an asteroid were on a collision course with Earth. As opposed to the ideas of physically pushing the asteroid or blowing it to bits, the Lu/Love plan is to position a spacecraft close to the asteroid and use the gravitational attraction to alter the asteroid's path.
