Answer:
NASA technology, Remote Sensing, the search can be narrowed. Remote sensing techniques use satellites to help observe and measure objects from a distance. One part of remote sensing involves taking pictures. With images like the ones from NASA's LandSat Satellites, paleontologists use remote sensing to locate areas in the Gobi where fossils are most likely to be found. LandSat sensors measure different wavelengths of reflected sunlight and emitted thermal radiation. The data are beamed back to Earth, where they can be made into images. Paleontologists analyze these images, looking for rock formations most likely to yield fossils.
