Science Question and Answer - New Horizons Mission

New Horizons Probe (c) NASA/Johns Hopkins University

Answering all your cosmic conundrums this week are Drs. Chris, Dave and Phil who discuss why blood is red, the size of the ozone hole, how to make magnets, the best way to get rid of excess mucus, and sticking with the gooey theme, Professor Adam Summers from the University of California Irvine discusses how some tarantulas keep a firm hold on the ground by producing sticky silk in their feet. Moving much further away from terra firma, New Horizons scientist Dr Hal Weaver from Johns Hopkins University talks about the mission to Pluto, what they hope to find there and why the Kuiper Belt objects are so intriguing, and in Kitchen Science, Derek Thorne and Hugh Hunt carry out their own launch by throwing engineering textbooks high into the air.
