The traditional astronaut's 'low residue' breakfast of steak and eggs pays tribute to the oldest and wisest strategy for going to the bathroom in space, which is to do everything possible to avoid it.

While capsules like Soyuz and the Crew Dragon are equipped with a rudimentary toilet kit, astronauts use a mix of drugs, diet, and occult knowledge passed down the generations to keep from having to use it.

It can take more than two days for a Crew Dragon capsule to reach the space station, but the crew in the cramped spacecraft is expected to save the real fireworks for the relative comfort of the station.
