As part of a new series of experiments aboard the International Space Station to study how plants grow in microgravity, astronauts have planted and cultivated an entire flower garden. This weekend, astronaut Scott Kelly tweeted a signficant step in their research: this firey zinnia bloom, the first flower grown entirely in space. Plants like lettuce have aready been grown and eaten aboard the ISS, but the VEG-01 project is meant to explore how astronauts will eventually grow more complex foods like tomatoes. (via Neatorama)
