Astronomy Science Fair Project

Keeping Astronauts Warm on Mars

Keeping Astronauts Warm on Mars | Science Fair Projects | STEM Projects
Astronauts exploring Mars need a special kind of suit to keep them warm. In this experiment, we'll test different fabric combinations to see which one works best in the extreme temperatures of Mars.


The hypothesis is that spacesuit prototype #3 will be the prototype that will conserve more heat than prototypes #1 and #2.

Method & Materials

You will make three different combinations of fabrics, glue the fabrics for each combination together, sew all edges of prototypes together, fill plastic containers with water, slide bottle in spacesuit prototypes, measure temperature of outside environment, and wait 1 hour and record temperature.
You will need four thermometers, polyester lycra fabric, camouflage fabric, fleece fabric, aluminized mylar, foam fabric, flannel backed vinyl, vinyl, rubber coated nylon, nylon cordura fabric, scissors, liquid stitch, brown thread, sewing needle, heating device, plastic containers, ice chest cooler, dry ice, water, and rubber gloves.


The results of the experiment showed that prototype #3 had the least average change in temperature. This experiment was limited to analyzing the effects of the environment on temperature change of an object inside the prototype spacesuits.

Why do this project?

This science project is interesting because it could help NASA test different types of space suit fabrics for Mars.

Also Consider

Experiment variations to consider include testing for durability and tensile strength for protection from damage due to jagged rocks and micrometeoroids, and testing different temperatures to see how the fabric combinations respond.
