The First Docking in Space
On March 16, 1966, Neil Armstrong and David Scott flew Gemini VIII to the first docking of two spacecraft in orbit. Moments later, it turned into one of the most dangerous rides of the space race. This is the story behind the shirt.
Two Launches, One Morning
- 10:00 a.m. · Launch Complex 14An Atlas rocket lifted the unmanned Agena target vehicle into orbit from Cape Kennedy.
- 11:41 a.m. · Launch Complex 19An hour and 41 minutes later, a Titan II sent Armstrong and Scott after it. It was the first spaceflight for both men.
The Chase
- Armstrong and Scott spent hours closing the gap on the Agena, firing their thrusters to match its orbit.
- After flying around the target to inspect it, Armstrong eased Gemini VIII's nose into the Agena's docking collar.
- For the first time, two spacecraft were joined together in orbit.
The Wild Ride
- Not long after docking, the joined spacecraft began to roll. A thruster on Gemini VIII was stuck firing, though the crew didn't know that yet.
- Suspecting the Agena, they undocked. Free of its weight, Gemini VIII spun even faster, approaching one full revolution per second and blurring the astronauts' vision.
- Armstrong shut down the main maneuvering thrusters and used the separate reentry control thrusters in the nose to stop the spin.

Coming Home Early
- Mission rules required the crew to come home once the reentry thrusters had been used, so a planned three-day flight ended after one more orbit.
- Gemini VIII splashed down in the western Pacific, about 620 miles south of Yokosuka, Japan, within two miles of the predicted point.
- Air Force pararescuers stayed with the crew until the destroyer USS Leonard F. Mason arrived to pick them up.
Why It Matters
- Gemini VIII proved two spacecraft could rendezvous and dock in orbit, the exact skill Apollo would need to land on the Moon and bring its crews home.
- Later Gemini spacecraft got switches that let astronauts shut off a single malfunctioning system, a direct lesson from this flight.
- Three years later, Neil Armstrong commanded Apollo 11. David Scott went on to command Apollo 15.
