NASA’s Earth science satellite fleet

When most people think about NASA, Earth is not the first thing that comes to mind. Ours agency conjures up thoughts of leaving Earth behind, so it is usually Apollo astronauts, the Moon, Mars, and Hubble views of stars and galaxies that people associate most strongly with NASA’s brand.
However, many astronauts have found the view back at Earth is as compelling as anything else they’ve seen. William Anders, the Apollo 8 astronaut who took the influential Earthrise photograph on Christmas Eve 1968, put it well: “We came all this way to explore the Moon, and the most important thing is that we discovered the Earth.”
Nearly a half-century later, studying Earth from space is a critical part of NASA’s mission. There are currently sixteen Earth-observing satellites operating in orbit around our planet. The oldest, the Tropical Rainfall Measuring Mission (TRMM) was launched in 1997; the youngest, Landsat 8, was launched in February 2013. Together the fleet monitors a wide range of environmental phenomenon relevant to climate change, weather prediction, fire monitoring, and the health of vegetation.
