Are You Smarter Than an Astronaut? Try These Brain Teasers to Find Out

Every kid dreams of someday becoming an astronaut. But despite what Hollywood films would have you believe, training to function in space isn't all fun and games in anti-gravity chambers. In addition to medical tests and psychological examinations, they have to pass a series of tests that measure their logic and problem-solving skills. Many of the questions take the form of puzzles, some of which will soon be shared in British astronaut Tim Peak's The Astronaut Selection Test Book: Do You Have What it Takes?

Peak is a member of The European Space Agency (ESA), and he bears the distinction of being the sixth person born in the United Kingdom to go on board the International Space Station. Recently, he shared three brainteasers that he had solve during his own selection process, and they are real doozies. You can try your hand at the puzzles yourself below.

Which combination of shapes should fill the missing square? And the answer is…

According to Peake, the right answer is B because "the pattern mirrors adjacent shapes but in different colors."

Wheel 1 and 2 have the same radius. If wheel 1 is being driven, will wheel 2 rotate as fast as wheel 1, faster than wheel 1, slower than wheel 1, or doe wheel 2 not rotate at all? And the answer is…

Peake says that "wheels of same radius at start and end of the sequence will spin at the same speed."

If a line runs through the middle of a 3-D shape such that it is equidistant from all surfaces, what does the shape look like? And the answer is…

Peake said that, "for the mathematicians, it's essentially asking for the locus of a straight line."
