Article Summary
To paraphrase an old saying, if the astronaut can’t go to the asteroid, the the asteroid must come to the astronaut. In a study released by the Keck Institute for Space Studies, researchers outlined a mission to tow an asteroid into lunar orbit by 2025 using ion propulsion and a really big bag. The idea is to bring an asteroid close to Earth for easy study and visits by astronauts without the hazards and expense of a deep space mission.
