You have four cargo slots and somebody wants to bring a pillow. Fair enough. What comes off the spacecraft to make room? Give the youngest astronaut first pick and watch a packing list turn into a very lively negotiation.
What is National Space Day?
National Space Day falls on the first Friday in May. It encourages curiosity about space exploration and the science and engineering that help people investigate worlds beyond Earth.
A day designed to spark future missions
Lockheed Martin started Space Day in 1997 as an educational initiative encouraging young people to explore science, engineering, and aerospace careers. Space Center Houston describes that learning purpose in its account of the day. You do not need a telescope to join in: asking how a spacecraft carries its supplies is already a useful space question. Space Center Houston’s Space Day history.
A simple way to enjoy the day
Give your pretend crew a limited number of cargo spaces and a mission to complete. Ask what they need and what they can leave behind. The packing activity below makes those tradeoffs easy to picture.

National Space Day date reference
Load the capsule
Set four coins on the table to mark your cargo limit. Cut out the six equipment cards. In our pretend mission the ship already carries air, food and water. Pick a job for the crew, such as photographing a crater, before anyone claims a slot. A camera suddenly looks much more important than a spare blanket.
Make room for the crew
Sketch the cabin from above. Where can a sleepy astronaut stretch out? Tape the four chosen cards beside the drawing and point to where each item lives. Tell the commander one thing that might float away and how the crew would secure it.
Call mission control
An adult can be the radio operator in the next room. Ask for three details: what the crew sees, which tool they actually used, and what they wish they had packed. Record the answers before letting the radio operator take the next flight.
