Able and Baker
The first two monkeys to survive their trip into space are presented at a NASA press conference in 1959. Able, on the left, a seven-pound rhesus monkey, and Baker, an 11-ounce squirrel monkey from Peru, withstood forces 38 times the normal pull of gravity and endured weightlessness for about 9 minutes during their historic flight. Able died four days after returning to earth during a relatively simple surgery to remove an infected electrode. Baker lived until 1984.
