There are a whole lot of people hoping they have the right stuff to go to space.
NASA announced last week a record 18,300 applications were submitted for its astronaut candidate training program. That's nearly three times the number the agency received in 2012 -- the most recent class.
Before that, the previous record was set in 1978, when 8,000 people applied.
Now, of those thousands, only 8 to 14 will be chosen. Since 1959, there have only been 338 astronauts. Once final candidates have been selected, they will undergo two years of basic training on things from spacewalking to learning Russian.
