During the first docking, Pilot David Scott was planned to perform an ambitious, two-hour-and-10-minute extra-vehicular activity ( EVA ), which would have been the first since Gemini IV . On a tether for one and a half revolutions around the Earth, Scott would have retrieved a nuclear emulsion radiation experiment from the front of the Gemini's spacecraft adapter, then activate a micrometeoroid experiment on the Agena.
