  • The European components (Columbus, Harmony, Tranquility, the Leonardo MPLM, and the Cupola) were manufactured by the European Space Agency (ESA). The Columbus module was constructed at the Astrium Space Transportation facilities in Germany with many other contractors all over Europe. The other modules were initially built at the Thales Alenia Space factory in Italy and then delivered through aircraft to the John F. Kennedy Space Center SSPF for launch processing.
  • The Japanese Experiment Module (Kibō) was manufactured at the NASDA (now known as JAXA), Tsukuba Space Center (TKSC), and the Institute of Space and Astronautical Science (ISAS). The Kibo was then transported to SSPF for launch processing.

  • The astronauts use crew cabins or quarters for sleeping.
  • A crew cabin is big enough for a person and has a sleeping bag, in which an astronaut sleeps.

How Astronauts Sleep In The ISS

  • After a long working day, astronauts need a good night’s sleep.
  • At a certain time, the crew members go to bed, then wake up and get ready for work again.
  • There is no ‘up or down’ in space. However, there is microgravity due to which the astronauts are weightless and can sleep in any direction.
  • When sleeping, they attach themselves to a wall or something else to not float around and jolt into something in sleep.
  • Eight hours of sleep is generally scheduled at the end of each mission day for an astronaut.
  • Similar to the Earth, an astronaut may wake up in the middle of sleep to use the toilet.
  • The sleep pattern of an astronaut can be disturbed by different things, such as motion sickness or excitement.
  • Astronauts reported that they have dreams and nightmares while sleeping in space.
  • Some are also reported snoring during sleep.

 Toilet At The International Space Station

  • ISS has two space toilets, located in the Zvezda and Tranquility modules.
  • Both the toilets are of Russian designs and use fan-driven suction systems to direct the waste in a weightless environment, which is similar to the Space Shuttle Waste Collection System.
  • The toilet seat is equipped with restraining bars that are spring-loaded to ensure a good seal.
  • There is a lever in the toilet, which operates the slides of a suction-hole to open and a powerful fan. The powerful stream of air carries away the waste.
  • Solid waste is collected in bags and stored in containers made up of aluminum. When a container becomes full, it is transferred to a Progress spacecraft which then discards it.
  • A hose in the front of the toilet evacuates the liquid waste. It is then transferred to the Water Recovery System, which recycles it into drinking water.

Hygiene At The International Space Station

  • Showers were introduced on Space Stations during the early 1970s on Skylab and Salyut-3.
  • However, showers are not featured on the International Space Station, instead, water jets and wet wipes are used. The soap they use is released from a container similar to a toothpaste tube.
  • An edible toothpaste and rinse-less shampoo are provided to the crew to save water.

  • At the elevation of the ISS, gravity is about 90% stronger than the Earth’s surface.
  • However, objects are in the state of continuous freefall in orbit, which results in an apparent state of weightlessness.

Why Astronauts On The International Space Station Feel Weightless

  • Astronauts on the International Space Station feel weightless because there is no force to counteract the gravitational force.
  • So the astronaut is falling continuously.
  • As the astronaut is also moving in a forward direction with a very fast speed, he does not crash into the Earth but rather falls continuously around the Earth.
  • This condition creates an apparent state of weightlessness on the ISS.

What Do They Eat On The International Space Station – ISS Food

  • On the International Space Station crew members eat food transported from the Earth.
  • Most of the food delivered to the Space Station is vacuum-sealed in plastic bags. Cans are usually avoided because of weight and expensive transportation.  
  • Crew-members do not regard preserved foods mostly. As the test is reduced at microgravity, so efforts are made to make the food tasty and palatable, for example, more spices are added than regular cooking.
  • The crew eagerly awaits the arrival of any spacecraft from the Earth, as it carries fresh vegetables and fruits for them.
  • Special care is taken that the food does not produce crumbs. Condiments are usually preferred in the liquid form rather than solid to avoid the contamination of the Station’s equipment.
  • There are individual food packages for each crew member. He/she cooks them in the onboard galley. 
  • The galley has two food warmers, a refrigerator (which was added in November 2008), and a water dispenser that provides both cold and warm water.
  • The drinks provided to them are in the form of dehydrated powder, which they mix with water before consumption.
  • They sip drinks and soups with straws from the plastic bags.
  • They eat solid foods with a fork and knife, which are attached through magnets to a tray otherwise it would float away.
  • Any food materials and crumbs that float away are collected to prevent their clogging in the air filters and other equipment of the Space Station.
