Cal Tech’s Keck Institute for Space Studies (KISS) commissioned a study of the feasibility of bringing an asteroid to the International Space Station beginning in September 2011 and issued its report earlier this month.
The targeted asteroid would weight about 500 metric tons and measure roughly 7 meters across.
A robotic asteroid retrieval mission would contribute toward an invaluable advance in human spaceflight, a leap forward in several areas in which humankind must make progress in order to advance into the solar system.
