It’s impressive how much detail Juno was able to capture even on the night side. What I love about Io is how it’s instantly recognizable. Nothing even remotely resembles it in the solar system.
Cue the flat-earthers who are going to jump on this while completely ignoring all other aspects including the gravity required to make this happen, and somehow claim this is scientific proof that they were right.
Salad is good for you, generally speaking, so growing fresh greens in orbit seems like a winning way for space farers to stay healthy. New research suggests that as nutritious as space salad might be, it could pose something of a risk to astronauts.
The problem is growing leafy plants like lettuce and spinach in space can come with a side dish of bacteria, according to a new study from a team at the University of Delaware. In tests on plants grown in simulated microgravity, they were shown to actually be more susceptible than normal to the Salmonella enterica pathogen.
Sounds like not a big problem at all. Seems like they'll just have to use appropriate cleaning methods. Even in the worst case scenario they would probably just have to use food irradiation.
