The Apollo astronauts also dumped tools and television equipment that they no longer needed.

What went wrong with Gemini 3?

Two small failures occurred in-flight. The first was an experiment testing the synergistic effect of zero gravity on sea urchin eggs. A lever essential to the experiment broke off when pulled. The second involved the photographic coverage objective.
