^* If the plants are edible, a conflict can arise. As much as astronauts miss nature, they miss fresh food. The diary of cosmonaut Valentin Lebedev includes a story about a batch of onion bulbs taken on board Salyut as part of an investigation of plant growth in zero gravity. “As we were unloading the resupply ship, we found some rye-bread and a knife. So we ate some bread. Then we saw the onion bulbs we were supposed to plant. We ate them right then and there, with bread and salt. They were delicious. Time went by and the biologists asked us, ‘How are the onions?’
      “‘They are growing,’ we answered….
      “‘Do they have shoots?’ Without any hesitation we replied that they even had shoots. There was great excitement at the communication station. Onions have never bloomed in space before! We asked to speak to the head biologist in private. ‘For god’s sake,’ we told him, ‘don’t get upset, we ate your onions.’”
