Space Food Explorer
Mission notes: meals in orbit
On Earth, gravity pulls food and drink down towards a plate or cup. In orbit, people and loose objects float because they are in continuous free fall around Earth. A crumb could drift into equipment, and an ordinary drink could break into floating blobs. Astronauts use sealed packages and carefully manage every bite and sip. Space-station meals are chosen to stay safe and edible for a long time. Some foods are heat-treated and sealed in pouches. Freeze-dried foods have most of their water removed while frozen, making them light to transport. Water can be added to some dried meals before eating. Fresh fruit may be available sometimes, but it does not keep for long. Astronauts use spoons, straws and fasteners such as hook-and-loop strips to keep food and equipment from drifting away. There is no single menu for every mission. A meal must be nutritious, safe to store, practical to eat and enjoyable. Planning meals carefully helps a crew stay healthy and makes a long mission feel more comfortable.
Challenge 1: Plan a safe meal
Use the mission notes for Questions 1–6.
- It may float into equipment.
- It becomes too heavy to lift.
- It melts in the air.
- It makes gravity stronger.
- Freeze-dried food
- Heat-treated, sealed food
- Fresh fruit
- Ready-to-eat packaged food
- Heated and sealed in a package to help it stay safe to eat.
- Can be eaten without adding water first.
- Can be eaten fresh but does not keep for long.
- Most of its water is removed while it is frozen, so it is light to transport.
Challenge 2: Design the crew’s food pouch
Imagine you are designing a pouch for a dried meal. Draw it and label features that would make it useful in orbit.
