Last Week in Science

So here is another list of the amazing things that I heard about last week in science:
     1) Colonization of Mars is not as far away as you might think
     2) China has developed a laser cannon to shoot down spy drones
     3) Fusion Reactors may be available for public purchase in 10 years.
Fusion Reactors are a reeally reaallly good source of energy. There are no harmful waste products, they're cheaper to run, and they produce WAY more energy than any other forms of energy. We don't have that much information yet, but this will really be a topic to follow up on.

PS. 4) The Rosetta spacecraft is due to land on an asteroid in 7 days. on November 12!
