Investigating Noctilucent Clouds
NASA’s Aeronomy of Ice in the Mesosphere mission was designed to study noctilucent, or night-shining, clouds. In the ten years since launch, AIM’s data have also helped scientists understand a host of upper-atmosphere phenomena, from radio echoes to giant, planet-scale atmospheric waves.
Where are the Small Worlds?
In this innovative new game-like exploration of the solar system, learners observe the motion of different worlds to determine their location in the solar system, then launch probes to search these small worlds.
New Insights into 'Ocean Worlds' in Our Solar System
Cassini scientists announced that a form of chemical energy that life can feed on appears to exist on Saturn's moon Enceladus, and Hubble researchers report additional evidence of plumes erupting from Jupiter's moon Europa.
NASA continually looks outward to find and learn about planets in our solar system and beyond, but no planet is better studied than the one we actually live on. Celebrate Earth Day 2017 by "adopting" one of 64,000 individual pieces of Earth as seen from space.
Robotic Prototypes for Icy Worlds
Since 2015, NASA's Jet Propulsion Laboratory in Pasadena, California, has been developing new technologies for use on future missions to icy ocean worlds. That includes a subsurface probe that could burrow through miles of ice; robotic arms that unfold to reach faraway objects; and a projectile launcher for even more distant samples.
The Countdown Has Begun
Supporting graphics, video and background information about Cassini's Grand Finale are all available in the online toolkit.
