Who We Are  

 

Establishing a permanent research base on Mars can be a first step toward determining the possibility of future large-scale human settlements there.
In Mars City — Balloon Physics Challenge, students use various tools to learn more about Mars. Among those tools will be unmanned balloons.
In “Task 1 — Balloon Physics,” students learn about research balloons, why balloons fly, and how they are designed. Each team’s objective is to design, construct, and fly a research balloon on Mars. To help achieve this objective, students use the Balloon Physics Apps to learn more about the physics of balloon flight, the components of a typical research balloon on Earth, and how best to launch and fly a balloon on Mars.

Earth Balloon
Lifting Gas

Calculate the radius, volume, and weight of a sphere of a selected mass of air, hydrogen, helium, carbon dioxide, or methane on Earth at sea level temperature and pressure.



Earth Balloon
Envelope

Calculate the volume of a balloon and the mass and weight of the balloon envelope for selected balloon radii, envelope materials, and envelope material thicknesses.



Hot Air Balloon
Lifting Gas

Calculate the volume, mass, weight, and buoyant force for a sphere of air on Earth at sea level temperature and pressure for selected radii and selected temperatures equal to or greater than ambient temperature.



Mars Balloon Lifting Gas
Calculate the volume, mass, and weight of a sphere of hydrogen, helium, or Martian atmospheric gas of a selected radius at conditions of temperature and pressure associated with the mean Martian surface elevation.



Mars Balloon Envelope
For a balloon envelope constructed of layers of Mylar, Kevlar scrim, and low-density polyethylene, calculate the volume of the balloon, and the mass and weight of the balloon envelope for selected balloon radii and envelope material thicknesses.
