Instruments of the Mars Global Surveyor Mission
It has been more than 30 years since America's first exploratory missions
to Mars. Here are some of the instruments carried onboard Mars Global Surveyor (called MGS for short). Many of these instruments were inherited from the Mars Observer
mission. These instruments are designed to study the weather and surface of Mars:
- A camera to produce daily weather images
of Mars similar to weather photographs of the
Earth shown on the nightly news.
- An instrument to measure the heights of things.
- An instrument to measure the warmth of the surface of Mars.
- This instrument will also make maps of minerals found on the surface.
- An instrument to study the magnetic
properties of Mars.
Radio signals sent to Earth will reveal the precise shape of the
planet, which helps scientists figure out what the inside of Mars is like.
