NASA has selected some great pictures for Flickr. Here’s the caption for the image above, “The Original Seven”:

In this 1960 photograph, the seven original Mercury astronauts participate in U.S. Air Force survival training exercises at Stead Air Force Base in Nevada. Pictured from left to right are: L. Gordon Cooper, M. Scott Carpenter, John Glenn, Alan Shepard, Virgil I. Grissom, Walter Schirra and Donald K. Slayton. Portions of their clothing have been fashioned from parachute material, and all have grown beards from their time in the wilderness. The purpose of this training was to prepare astronauts in the event of an emergency or faulty landing in a remote area. Forty-five years ago today on May 24, 1962, Scott Carpenter went on to fly the second American manned orbital flight. He piloted his Aurora 7 spacecraft through three revolutions of the Earth, reaching a maximum altitude of 164 miles. The spacecraft landed in the Atlantic Ocean about 1,000 miles, about 1,609 kilometers, southeast of Cape Canaveral after the 4 hour, 54 minute flight. Image credit: NASA
