PGM-19 Jupiter the 10 "g" (100 m/s²) of launch, eight minutes of weightlessness and 40 "g" (390 m/s²) of reentry at 10,000 mph (4.5 km/s). The nose cone sank downrange from Cape Canaveral and was not recovered. Another biological flight was launched on 28 May 1959. Aboard Jupiter AM-18 were a seven-pound (3.2 kg) American-born rhesus monkey, Able, and an 11-ounce (310 g) South American squirrel monkey, Baker. The monkeys rode in the nose cone of the missile to an altitude of and a distance of down the Atlantic Missile Range from Cape Canaveral. They withstood accelerations of 38 "g" and were
Miss Baker nose with model cement, and she was fitted into a snug capsule of shoebox size, 9¾ × 12½ × 6¾ inches (24.8 × 31.8 × 17.1 cm) insulated with rubber and fiberglass. Life support was an oxygen bottle with a pressure valve, and lithium hydroxide to absorb exhaled carbon dioxide and moisture. On May 28, 1959, at 2:39 am, a Jupiter rocket lifted Miss Baker and Miss Able to an altitude of through an acceleration of 38 gs for a 16-minute flight which also included 9 minutes of weightlessness. The flight traveled downrange from the pad at Cape Canaveral launch
