Space projectile takes icy test

UK engineers have tested a projectile technology they believe could be used to explore the Solar System.

The steel penetrator was fired at a 10-tonne cube of ice to simulate the surface of Jupiter's moon Europa.

It hit the block at a speed of 340m/s and decelerated rapidly, but its structure remained intact, as did its interior components.

Researchers say the penetrator would be a robust and inexpensive way to land instruments on other worlds.
