This quiz will challenge your knowledge of Uranus's strange rotation, chilly atmosphere, and curious collection of moons.
In space, the one thing more important than ensuring access to food, water, and waste disposal (combined!) is the need for a steady supply of breathable air. Where the International Space Station (ISS) and other missions in Low Earth Orbit (LEO) can be resupplied regularly, missions operating in deep space will need to produce their own. There are several ways to go about this. One way is to use bioregenerative life support systems (BLSSs), which utilize photosynthetic organisms (like cyanobacteria) that take in carbon dioxide and produce oxygen gas and edible algae.
