Space



This is about living in space and the things we take for granted everyday on earth. **!** **Brushing teeth** **!** **Showering** **!** **Dressing** **!** **Preparing and eating food** **! using the toilet **

​Gravity stops things on Earth from flying out into space. Simple items that we use daily require gravity to work, e.g. toilets, chairs, etc. In space these items need to be used in a different way. a simple question is how many astronauts it takes to make a simple sandwich in space? well it takes 2 - one to hold the peanut butter and the other to hold the bread and spread. Food taken into space must be safe, nutritious and easily ingested and digested and not cause any hygiene or gastro problems. Packaging must also be carefully considered. It can be quite dangerous for onboard equipment to have crumbs or globs of liquid floating around so packaging has to prevent spillage. It also has to be lightweight, be easy to dispose of, survive temperature, pressure, acceleration and vibration. Drinks are sucked from pouches with valved straws – the valves are needed to stop the liquid from coming out because of microgravity. Foods are sucked out like through a straw of similar containers or glued into the container with sticky sauces or gravies, which keeps the food on eating utensils. Hardly any washing up is done because food containers are disposable. Eating utensils and food trays are cleaned with wet wipes.
