NASA planning to capture asteroid with robot

The agency wants to use a robot to grab a small space rock and drag it to orbit around the moon. That'll allow astronauts to visit and explore it easily.

NASA will need the money and new technology to pull this off and they need to find an asteroid that's small and stable enough to manipulate.

All of this is being done to develop new technology that can be used to send NASA astronauts to Mars.
