When the first Christian missionaries landed in South America in the sixteenth century, they found a plant which seemed to be a very good omen for the success of their mission.

Astronauts actually grow 2 to 3 inches taller (5 to 8 centimeters) when they are in space! The stretching can cause them some pain; many astronauts have back pain while they are in space and the stretching can potentially injure nerves.

1 Natural space debris consists of small pieces of cometary and asteroidal material called meteoroids. 2  We see these as meteors when they travel through the Earth's atmosphere. 3  Artificial space debris is any non-functional man-made object in space (usually orbiting the Earth). Small pieces of space debris (less than 1/10 mm) are prolific enough to cause erosion of optical surfaces. 2  This is like sandblasting, and can ruin telescope mirrors, and decrease the efficiency of solar cells.
