Technology in space penetrator

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.
Marie-Claire Perkinson, the project's industrial leader from Astrium UK, told Jonathan Amos about the construction of the penetrator.
