Europa Clipper's mission is primarily focused on:
Europa Clipper's mission is primarily focused on:
- Redirecting Europa's orbit to prevent future collisions with Jupiter.
- Establishing a permanent human settlement on Europa.
- Studying Europa to determine if it possesses the necessary conditions for life. (correct)
- Mining rare minerals from Europa's icy crust for use on Earth.
What is the primary source of energy that prevents Europa's underground ocean from freezing, potentially supporting life?
What is the primary source of energy that prevents Europa's underground ocean from freezing, potentially supporting life?
- Radioactive decay of elements within Europa's core, releasing thermal energy.
- Direct solar radiation penetrating the icy crust and warming the ocean beneath.
- The gravitational pull of Jupiter, which creates heat through stretching and squeezing of Europa's interior. (correct)
- Geothermal vents located on the ocean floor, similar to those on Earth.
According to scientists, which of the following is a crucial element that Europa's surface may possess, making it a potential habitat for life?
According to scientists, which of the following is a crucial element that Europa's surface may possess, making it a potential habitat for life?

Study Notes
- NASA launched a mission to find new frontiers for the search for life, this time to Jupiter's fourth-largest moon, Europa.
- The Europa Clipper spacecraft launched on October 14, 2024, from the Kennedy Space Center in Florida.
- The mission will uncover the secrets of Europa.
- About an hour and 10 minutes after launch, NASA confirmed the spacecraft successfully entered orbit.
- Europa Clipper deployed its solar arrays to power the spacecraft throughout its journey.
- NASA Administrator Bill Nelson congratulated the Europa Clipper team for beginning its journey to an ocean world beyond Earth.
Why Europa?
- Europa is a top candidate for alien life because it may have the key ingredients necessary for life.
- Liquid water, energy, and the right chemical elements are all considered key ingredients.
- Scientists believe under Europa's icy crust lies a large saltwater ocean.
- Europa's ocean may contain twice as much water as Earth's oceans.
- The icy moon's energy source likely comes from Jupiter's gravity, which stretches and squeezes Europa's interior, creating heat.
- This heat prevents Europa's underground ocean from freezing and might support certain forms of life.
- Europa's surface may have essential elements for life, like carbon, nitrogen, and oxygen, possibly creating conditions for microbial life.
Getting to Europa
- Jupiter is about 480 million miles (772 million km) from Earth.
- Europa Clipper will travel 1.8 billion miles (2.8 billion km) over 5.5 years to reach its destination.
- The spacecraft will use "gravity assist" maneuvers to gain speed.
- Europa Clipper will fly past Mars in February 2025 for its first boost.
- In December 2025, it will swing by Earth for a final push, putting it on course for Europa.
The Mission
- If all goes as planned, Europa Clipper will enter Jupiter's orbit in April 2030.
- It will spend about a year preparing for its first flyby of the moon.
- Over the next three years, the spacecraft will fly over Europa 49 times, with each pass over a different area to map the entire moon.
- Although it will not land on Europa, it will get as close as 16 miles (25 km) to its surface.
- The nine instruments on the Europa Clipper will help scientists estimate the thickness of Europa's icy shell and understand the ocean beneath it.
- NASA hopes to learn more about the composition of the water.
- NASA asserts that the mission's goal is not to directly search for life on Europa, but to determine if there are areas below the icy moon's surface that could support life.
- Once its mission is complete, the spacecraft will deliberately crash into the surface of Ganymede, Jupiter's largest moon.
- Exploring the unknown with Europa Clipper will help to better understand whether there is the potential for life not just within our solar system, by exploring billions of moons and planets beyond the Sun.
