Beginning this month, NASA is launching a suite of six next-generation, Earth-observing small satellite missions to demonstrate innovative new approaches for studying our changing planet.

These small satellites range in size from a loaf of bread to a small washing machine and weigh from a few to 400 pounds. Their small size keeps development and launch costs down as they often hitch a ride to space as a “secondary payload” on another mission’s rocket – providing an economical avenue for testing new technologies and conducting science.

“NASA is increasingly using small satellites to tackle important science problems across our mission portfolio,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate in Washington. “They also give us the opportunity to test new technological innovations in space and broaden the involvement of students and researchers to get hands-on experience with space systems.”

Small-satellite technology has led to innovations in how scientists approach Earth observations from space. These new missions, five of which are scheduled to launch during the next several months, will debut new methods to measure hurricanes, Earth’s energy budget, aerosols, and weather.

“NASA is expanding small satellite technologies and using low-cost, small satellites, miniaturized instruments, and robust constellations to advance Earth science and provide societal benefit through applications,” said Michael Freilich, director of NASA’s Earth Science Division in Washington.
