A preauthorization is a temporary hold placed on a credit or debit card. It is not an actual charge, although it does temporarily make the hold amount unavailable until the settlement or transaction clears. Companies use preauthorizations to help secure payment.
Astronaut is the term the US uses for a person who goes into space, cosmonaut is the Russian term. The first astronaut to fly into space was Alan Shepard, who flew the Mercury spacecraft Freedom 7 on a 15-minute suborbital flight on May 5, 1961. However, the first person to fly in space was Yuri Gagarin, who orbited the earth three times on April 12, 1961. Although this was 23 days before Shepard's flight, since Gagarin flew on Soviet spacecraft he was a cosmonaut, not an astronaut.
Navy Lieutenant Commander Chaffee, aged 31, had never flown in space before. Air Force Lieutenant Colonel Grissom, 39, was the first American to make two flights. Air Force Lieutenant Colonel White, 35, made America's first space walk. It is feared the disaster on launch pad 34 could delay America's plans to put a man on the Moon by as much as a year.
