Question: What do you know about Europa clipper probe?

I’ll be honest I’ve never heard of the Europa clipper probe before now but after a quick google search it sounds really interesting! I’ve put what AI gave me below for anyone else that wants to learn more!

The Europa Clipper is a NASA mission set to explore Europa, one of Jupiter’s largest moons, which is a prime candidate for harboring extraterrestrial life. Scheduled for launch in 2024, it aims to investigate Europa’s icy surface and subsurface ocean for signs of habitability. Here’s an overview and some fascinating facts:

Mission Goals
Study Europa’s Ice Shell and Ocean: Europa is thought to have a global ocean beneath its icy crust. Clipper will investigate the thickness of the ice, the depth of the ocean, and the potential for liquid water pockets.
Surface Composition Analysis: The spacecraft will map the moon’s surface to understand its geology and identify areas where future missions could land.
Assess Habitability: By analyzing surface chemistry and searching for water plumes, Clipper will determine if conditions exist that could support life.
Key Facts
Enceladus Rival: Europa is one of the solar system’s top contenders for life due to its subsurface ocean, possibly twice the volume of Earth’s oceans.
High-Tech Instruments: It will carry nine advanced instruments, including a radar to penetrate the ice, cameras, spectrometers, and a magnetometer to measure Europa’s magnetic field and infer ocean properties.
Flyby Strategy: Instead of orbiting Europa, Clipper will perform close flybys (nearly 50 planned) while orbiting Jupiter. This minimizes exposure to Jupiter’s intense radiation belts, which would damage onboard electronics.
Plumes of Water Vapor: Hubble Space Telescope observations suggest that water vapor plumes occasionally erupt from Europa’s surface. Clipper will fly through these plumes to sample and analyze their composition.
Galileo Legacy: The Clipper mission builds on the discoveries of NASA’s Galileo spacecraft, which found evidence of Europa’s ocean and magnetic field in the 1990s.
Power Source: It uses solar panels rather than nuclear power, making it one of the largest solar-powered spacecraft sent to the outer solar system.
Science Collaboration: The mission involves an international collaboration of scientists, including contributions from European and Japanese research teams.
Europa’s Tidal Heating: Europa’s proximity to Jupiter causes gravitational tidal forces, generating heat that keeps the ocean in liquid form despite freezing temperatures on the surface.
Fun Fact
Europa’s surface is so smooth that it’s considered one of the flattest objects in the solar system. The lack of craters and ridges suggests ongoing resurfacing due to subsurface activity, much like Earth’s plate tectonics.

The Europa Clipper mission is expected to revolutionize our understanding of icy worlds and the potential for life beyond Earth.
