Knives, forks, and spoons are cleaned with a wipe and stored for the next meal. The vacuum cleaner does double duty in space. Sometimes smaller objects float behind a panel or locker, and the vacuum helps astronauts retrieve those stray objects. Some jobs need to be done on a regular basis, and astronauts are in charge of doing these tasks. At launch, the LiOH canisters are stowed in a compartment under the middeck floor, and as the mission progresses, the canisters are pulled out of their containers and placed inside the Environmental Control and Life Support System, which filters the cabin air.
Astronauts have to bring in the mail, too.
There's no mailbox outside the cargo bay doors, but there is e-mail. All communications arrive at the Thermal Image Printer System where the astronaut on duty screens and distributes the messages. Some letters are notes from home, others are instructions and updates for the mission, and once in a while, someone from Mission Control sends a cartoon, just for fun. Both the Shuttle and ISS have a KU-band antenna that is deployed immediately after launch. This antenna sends and transmits video, live television, and other data at high rates of speed.
