There are many NASA satellites orbiting Earth right now. The Earth Now app displays the names of satellites that are collecting data about carbon emissions as well as climate change. While many people think of NASA as an organization that studies outer space and collects data far removed from Earth, NASA is vital in collecting information about our own Earth through remote sensing. Using remote sensing, we can obtain comprehensive information about our Earth that we could not obtain from the ground.
