NASA's Lucy probe is set to fly on April 20, 2025

NASA's Lucy probe is scheduled to make a significant flyby of the asteroid Donaldjohanson on Easter Sunday, April 20, 2025. Here are some detailed aspects of this mission: Mission Objectives: The Lucy mission aims to study the Trojan asteroids, which are believed to be remnants from the early solar system. By examining these asteroids, scientists hope to gain insights into the formation and evolution of the solar system. Asteroid Donaldjohanson: Named after paleontologist Donald Johanson, who discovered the famous Australopithecus fossil "Lucy," this asteroid orbits the Sun in a region known as the L4 Trojan camp, situated ahead of Jupiter in its orbit. It is one of the many Trojan asteroids that are thought to contain primitive materials. Flyby Details: During the flyby, Lucy will use its suite of scientific instruments to gather data about Donaldjohanson's surface composition, geology, and morphology. The close encounter will allow for high-resolution im...

New radar technique lets scientists probe invisible ice sheet region on Earth and icy worlds

A new radar technique developed by a graduate student allows imaging of the upper few feet of ice sheets on Earth and icy worlds. The technique uses instruments on airplanes or satellites to survey large regions quickly. The upper few feet of ice sheets are important for measuring melt on Earth or looking for habitable environments on icy worlds. Previous airborne or satellite techniques could not image this narrow region in detail.
