    For Giotto designers, one of the most difficult problems was how to ensure that the spacecraft survived long enough to snap close-up pictures of Halley's comet nucleus when the spacecraft and the comet were heading towards each other at a combined speed of 245 000 km/hour (equivalent to crossing the Atlantic Ocean in 11 minutes!). At this speed, a 0.1-gram dust particle would be able to penetrate 8 cm of solid aluminium. 11 March 2011 Giotto Whipple shield 2507 Votes: 8
