CAPE CANAVERAL - Just call them "The Great Eight."

Thirty-five years after selecting its first class of space shuttleastronauts in 1978 - the "Thirty-Five New Guys" - NASA on Monday introduced thefour men and four women who make up the Astronaut Class of 2013.

Talk about stiff competition. The eight were selected from more than 6,300applicants - the highest number since more than 8,000 vied for those 35 slotsin 1978.

There's an Army doctor who worked covert special operations in Iraq,Afghanistan and Africa.

There's an experienced aquanaut and under-ice diver who has done fieldworkin Antarctica and now is an assistant professor at Harvard Medical School.

NASA astronaut Mike Foreman, who gained entry to the Astronaut Office in1998 after his eighth application, said the quality of the newest class isdauntingly impressive.

"Personally, I'm just glad I'm not competing for a spot today," saidForeman, a veteran of two space shuttle missions. "These people are just likesuper-human people to me."

The new "astronaut candidates" will report to Houston in early August and begina year of basic training - a step that must be completed successfully to be puton flight status and be made eligible for selection to a crew.

The United States currently doesn't have a spacecraft to fly its ownastronauts, relying instead on Russia. But potential future missions includeflights to the International Space Station on U.S. commercial space taxis; orexploration missions to destinations that could include asteroids, the moon orMars.

The class includes:

The Class of 2013 has the highest percentage of women ever. Veteran NASAastronaut Janet Kavandi, director of Flight Crew Operations at Johnson SpaceCenter in Houston, said the gender split was not by design. "These were themost qualified people that we interviewed. I'm glad, I'm happy it turned outthat way. But we weren't seeking that when we started out."
