 Martian | 1. of or relatinanet mars. 2. a hypothetical or fictional inhabitant of Mars. |
| NASA. | National Aeonautics and Space Administration. |
| Mars. | The fourth planet from the Sun that is often referred to as the red plantet. |
| Spectrometer- | an instrument that utilizes a specific portion of the electromagnetic spectrum to identify materials or determine the elemental/chemical makeup of a material. The mars rovers had three such instruments: the Mossbauer Spectrometer, the Alpha particle X-Ray Spectrometer, and the Alpha Particle X-Ray Spectrometer.(APXS). |
| Antenna | a rod, wire, or other devica used to send and receive info. The mars rovers had three different antennas, the UHF, high gain, and low gain. |
| Orbiter | a spacecraft designed to stay in orbit around a body. |
| Hazcams | cameras mounted on the rocers that are utilized to safegaurd against the rover getting lost or inadvertently crashing into unexpected obstacles. They allow the rover to make it's own safety choices and to think on its own. |
| Navcam | 3 dimensional black and white cameras that support engineers and scientists in the planning of rover navigation. Mounted on the mast od the rocer. Work in cooperation with the hazcams. |
| Solar array | an ordered arrangement of panels designed to collect the suns rays as a source of energy for generation electricity or heat. The solar arrays look like wings on the back of each rover. |
| IDD | The instrument deployement device or the arm of the rocer the IDD is made of titanium and is used to maneuver the instruments that help scientists get up close and personal with the martian roack and soil. |
| MI | The miscroscopic imager is a combination of a microscope and a black and white camera and is used to ger close up imager of sediments, minerals, etc. |
| RAT | The rock abrasion tool is a high speed grinding tool used to remover weather surfaces from marian rocks. The RAT is often used in conjunction with the other tools like the MI and the spectrometers. |
| Magnet Arrays | an ordered arragement of magnets used to collect airborne iron containing dust particles. |
| Air bags | self inflation lobes that are used to protect occupants in a vehicle. The airbags in the Mars Rover mission surrounded the rover and were designed to cushion it upon landing. The air bags were made of Vectran, a material that is almost twice as strong as Kevlar. |
| Parachute | a cloth canopy that fills with air and allows a person or heavy object attached to it to descend slowly when dropped or that is released from the rear of an aircraft on landing to act as a brake. The parachute used in the Mars rover mission was made out of polyester and nylon and was exceptionally large in order to slow down the 18,000--19,000 pound rover. |
| Pancam | a high resolution color stereo pair of digital cameras used to image the surface, atmosphere, and sky of Mars. The cameras are located on a camera bar that sits on top of the mast of the rocer. The pancam has multispectral and carious filters which allow it to be used to identify minerals and learn about the atmosphere. |
| Sol | a martian day |
