Hey guys, Rob here. As you might know, I’m into the whole Mars rover thing, and I was psyched to find out they included an extra little package inside it this time — a helicopter. And even cooler, they fastened an actual swatch of fabric from the original Wright Brothers Flyer to the underside of its solar panel! So that got me thinking: I know they’re super careful about not letting bio material contaminate the moon or Mars, but what if, for this tiny swatch, they sort of forgot to check? What might happen?
