In Space Without a Spacesuit? 90 Seconds in the Vacuum
10 seconds of consciousness, and 90 seconds for “minimal permanent injury”. Andrew Tarantola summarizes the actual science of What Really Happens When You Get Sucked Out of an Airlock.
Some degree of consciousness will probably be retained for 9 to 11 seconds (see chapter 2 under Hypoxia). In rapid sequence thereafter, paralysis will be followed by generalized convulsions and paralysis once again. During this time, water vapor will form rapidly in the soft tissues and somewhat less rapidly in the venous blood. This evolution of water vapor will cause marked swelling of the body to perhaps twice its normal volume unless it is restrained by a pressure suit.

This is a question I occasionally get from students, so it’s good know where to find the studies, even though much of the evidence comes from accidents that happened to astronauts and cosmonauts.
NASA’s Build a Mission Game
NASA has an interesting site that lets you assemble the rockets to launch some of their upcoming missions. It’s a good way to learn what NASA’s up to, and to learn about how NASA’s rockets work.

It pays to remember that a solar eclipse occurs when the Moon passes between the Sun and the Earth. A lunar eclipse occurs when the shadow of the Earth passes over the Moon.

Morphing Art History
This amazing morphing of old masterpieces by Micaël Reynaud is worth enlarging. Warning: it’s about 10 Mb and you might just have to keep focused on the eyes to avoid motion sickness.
It’s similar to Philip Scott Johnson video below (you can find information about the artworks used here).
