NASA is planning for a robotic spaceship to lasso a small asteroid and park it near the moon for astronauts to explore, a top senator revealed Friday.
The robotic ship would capture the 500-ton 25-foot asteroid in 2019. Then using an Orion space capsule, now being developed, a crew of about four astronauts would nuzzle up next to the rock in 2021 for spacewalking exploration, according to a government document obtained by The Associated Press.
