Old Reliable

Gordo was one of the first monkeys to make it into space as part of NASA's space program. Eight monkeys had flown on NASA missions before him, five of whom went by the name of Albert.

Gordo's historic flight took place on December 13, 1958 when he took off from Cape Canaveral for a 15 minute flight into space. Even though he was weightless for over 8 minutes the on-board instruments indicated that Gordo enjoyed his journey into space. Scientists monitoring the flight were pleased to note that the only slight side effect Gordo suffered from the entry into space was a modest slowing of his pulse.

The intrepid pioneer Gordo.

The Mission

The rocket carrying Gordo into space would take off from the Atlantic Missile Range at Cape Canaveral, travel further than any monkey had ever travelled before - over 1,500 miles - and reach a height of 310 miles (500 km) before returning to Earth and landing in the South Atlantic, 1,302 nautical miles south of Cape Canaveral.

We all heard the rumors that they want to send a monkey up first. Well, none of us wants to think that they're gonna send a monkey up to do a man's work ... what they're trying to do to us is send a man up to do a monkey's work.

The Jupiter AM-13

The Jupiter IRBM (Intermediate Range Ballistic Missile) was originally developed by the US Army as a long-range successor to its PGM-11 Redstone missile, but was eventually taken over and deployed by the USAF for political reasons. It was also the only one of the United States' early stategic ballistic missiles with some mobility.

The Journey

Gordo wore a specially customised space suit custom made for a monkey about one foot tall. The space suit was fitted with instruments, including temperature meters and microphones which recorded his historic suborbital journey, considered one of the outstanding achievements of space research.
