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...

What's Causing Those Landslides on Mars? Maybe Underground Salt and Melting Ice

In the last few years, planetary scientists noticed bizarre streaks forming on the steep slopes of craters on Mars. The cause of these streaks has been hotly contested. Some believe they're evidence of liquid water forming on the surface of Mars, while others think they might be caused by lightly colored regolith tumbling down the steep slopes. A new idea proposes that they're actually caused by a combination of water, ice, and salt just under the Martian surface.
