Start with paper; add Shrinky Dinks, a microprocessor, heat, and voila! It's not quite that easy. But this engineering project might one day lead to a printable, flat spacecraft that folds itself.
Saturday, July 26, 2014
Two large radio telescopes have detected very brief, powerful bursts of radio waves, and so far, scientists have no idea what's causing them.
