Gemini X

Gemini 10 was designed to achieve the objectives planned for the last two missions—rendezvous, docking and EVA. As well as this it was also hoped to dock with the Agena Target Vehicle from the Gemini 8 mission. This Agena's battery power had failed many months earlier and this would demonstrate the ability to rendezvous with a passive object. It would be also the first mission to fire the Agena's own rocket, allowing them to reach higher orbits.
