Sounds like a great plan, huh...??
What could possibly go wrong...?? Oh, How 'bout it flying out of orbit in the process crashing into Earth... was that ever factored in the equation...??
That's right, scientists are coming up with a plan to capture an asteroid, tow it back to our moon and secure it into its orbit. Their reasoning for this is to bring a space rock closer 'to us' for convenient study rather than orchestrating a manned mission into deep space.
Luckily the proposed plan is to capture a small 20-foot wide asteroid (not a giant one as I feared).... unfortunately with today's ion propulsion technology the entire trip would take 10-years and cost $2.6-billion.
The proposal by the Keck Institute for Space Studies in California involves sending a robotic spacecraft out to ferry an asteroid back this way, snaring it in the moon's orbit. A captive asteroid would be a lot easier to pick apart and study, not to mention land on. It wouldn't be astronomically expensive, either: at $2.6 billion, the plan's cost lands in the same ballpark as the Curiosity rover. All this could happen sometime in the 2020s, according to the plan.
