Key Takeaways
- The Apollo-Soyuz Test Project was a landmark mission that brought American astronauts and Soviet cosmonauts together in orbit.
- The Hewlett-Packard HP-65 calculator was used as a backup device on the mission.
- The mission demonstrated the importance of international cooperation in space exploration and the need for innovative technology to support such endeavors.
Introduction to the Apollo-Soyuz Test Project
In 1975, NASA sent an unusual piece of technology into orbit: a pocket-sized Hewlett-Packard HP-65 programmable calculator carried aboard the Apollo-Soyuz Test Project. The calculator was not the spacecraftโs main computer, but a backup device programmed with rendezvous and guidance equations in case the Apollo Guidance Computer failed.
The Apollo-Soyuz Test Project was a landmark mission that brought American astronauts and Soviet cosmonauts together in orbit. The mission was designed to test the compatibility of rendezvous and docking systems as well as the possibility of an international space rescue.
The Hewlett-Packard HP-65 Calculator
The Hewlett-Packard HP-65 was introduced in 1974 and was the first magnetic card programmable handheld scientific calculator. Its design allowed users to store and load programmes using narrow magnetic cards that could be inserted into a reader beneath the calculator's display.
The calculator was compact by the standards of the period, measuring about 15.2 by 7.6 by 3.8 centimetres. Its kit included magnetic cards that could be used to save or load programmes, giving users a way to carry programmed calculations rather than entering them from scratch each time.
Technical Specifications of the HP-65
- First magnetic card programmable handheld scientific calculator
- Compact design: 15.2 x 7.6 x 3.8 cm
- Included magnetic cards for saving and loading programmes
The Apollo-Soyuz Mission
The Apollo-Soyuz Test Project launched on July 15, 1975, with three astronauts, and two days later, on July 17, it docked with a Soviet Soyuz spacecraft carrying two cosmonauts. The nine-day mission was designed to test the compatibility of rendezvous and docking systems as well as the possibility of an international space rescue.
During nearly two days of joint activities, the five crew members conducted five joint experiments and exchanged commemorative items. The mission was significant beyond the technology carried aboard the spacecraft, as it marked the first international partnership in space.
The Legacy of the Apollo-Soyuz Test Project
The Apollo-Soyuz Test Project paved the way for future international partnerships in space. The mission showed that cooperation between nations was possible, even in the midst of the Cold War.
The Hewlett-Packard HP-65 calculator, which was used as a backup device on the mission, is now part of the Smithsonian's collection. The calculator is a reminder of the innovative technology that was used on the Apollo-Soyuz Test Project and the importance of international cooperation in space exploration.
Key Figures
37 years passed between the Apollo-Soyuz mission in 1975 and the calculator's transfer to the Smithsonian's National Air and Space Museum in 2012. The calculator is currently not on display, but its survival provides a physical link to an era when a pocket-sized calculator, equipped with magnetic programming cards, could be considered useful backup equipment for a crew travelling into orbit.
