In a case of life imitating art, the European Space Agency is working on an experiment designed to launch a projectile into space and collide with an asteroid in an effort to alter its path away from Earth.
"Concepts are being sought for both ground- and space-based investigations, seeking improved understanding of the physics of very high-speed collisions involving both man-made and natural objects in space," the ESA announced in a statement.
The plan will culminate in a large-scale experiment in 2020, at which time two spacecraft will be launched in the direction of a 2,600-foot asteroid called 65803 Didymos. One spacecraft will intentionally crash into Didymos, attempting to alter its course, while the other records the results.

2. There are more and more requirements~ codes~ standards~ and...
