Study Notes
Europa Clipper Mission Overview
- Europa Clipper is a NASA mission launched October 14, 2024, to study Jupiter's moon Europa.
- It's the largest spacecraft built for a planetary mission.
- Goal is to determine if areas beneath Europa's icy surface support life, not to find life directly.
- Will orbit Jupiter and perform 49 flybys of Europa, getting as close as 16 miles (25 km) to its surface.
- Data from nine instruments will map Europa, study its icy shell and subsurface ocean, and analyze water composition.
- After mission completion, the spacecraft will crash into Ganymede.
Europa's Potential for Life
- Europa is a top candidate for alien life due to possible presence of liquid water, energy source from Jupiter's gravity, and essential elements (carbon, nitrogen, oxygen).
- Scientists believe a saltwater ocean exists beneath Europa's ice, estimated to be twice as voluminous as Earth's oceans.
- Tidal forces from Jupiter create internal heat, preventing the ocean from freezing.
Journey to Europa
- Europa Clipper will travel approximately 1.8 billion miles (2.8 billion km) to reach Jupiter over 5.5 years.
- Gravity assist maneuvers will be used, including a flyby of Mars in February 2025 and Earth in December 2025.
- Arrival at Jupiter's orbit is anticipated in April 2030.
Mission Timeline and Data Collection
- Europa Clipper will spend a year preparing for its first Europa flyby.
- Over the next three years, the spacecraft will conduct 49 flybys of Europa, mapping its entire surface.
- Collected data will help calculate the thickness of Europa's ice shell and analyze the composition of its ocean.
