Rovers and other autonomous robots will explore other planets. Miniaturizing our devices is essential for traveling greater distances. Humans can't venture far in space yet so our technology becomes our eyes and ears. Spacecrafts call home to Earth with sophisticated instruments. Testing spacecraft and instruments ahead of time is crucial to mission success. Discover how space technologies are used on Earth. See the look of the future.

Tunable Diode Laser-Based Gas Sensor

NASA has used the tunable diode laser-based gas sensor on aircraft and on balloons to study weather and climate, global warming and emissions from aircraft. Gas sensors aboard the space vehicles will measure water vapor and carbon dioxide in the atmosphere and soil of other planets. These measurements will provide information on the geological history of these planets and their potential to support life.
