Chimps in Space

Doctors examine Ham the chimpanzee after his Mercury space flight Feb. 1, 1961. Ham's name was an acronym for "Holloman Aero Med," the New Mexico base where he was kept. NASA said scientists used animals before astronauts to see it they could enter space and return to Earth unharmed.

Ham reaches for an apple. It was the first food the chimpanzee ate after a flight in a Mercury capsule launched by a Redstone rocket from Cape Canaveral, Fla. Ham's spacecraft, on Jan. 31, 1961, reached an altitude of 157 miles and traveled 5,857 miles an hour. Ham was weightless for six minutes. Astronaut Alan Shepard became the first American in space on May 5, 1961.

Kokomo Jr., a cousin of the space chimpanzee Ham, holds his nose after the flight of the Soviet cosmonaut Yuri Gagarin, the first human being in space, April 12, 1961. Like their U.S. counterparts, Russian engineers used animals before humans to test their ability to enter space and return safely to Earth.
