A Nasa animation demonstrates the agency's plan to capture an
asteroid in the moon's orbit. The idea is for a robot to catch a
small asteroid by pushing or pulling it into a stable orbit.
This would allow astronauts to explore the rock and test
samples. Nasa hopes to achieve this by 2021. The mission forms
part of a long-term goal to send astronauts to Mars Defend the
space base station from asteroids that are about to hit. Do this
using your spaceship. « previous1 next »
