NASA’s Juno Spacecraft Just Made The Closest Flyby Of Jupiter’s Moon, Europa

NASA’s Juno spacecraft has just made the closest flyby in more than 20 years of Jupiter’s moon Europa. The space probe passed 31 miles (50 kilometers) above the icy surface of Europa, which is believed to contain a vast ocean.

Why is the Juno spacecraft important?

The Juno spacecraft is important because it is providing new insights into the formation and evolution of Jupiter and our solar system. The data gathered by Juno will help us to better understand how planets form and how they evolve over time. Additionally, the Juno mission is helping to unlock the mysteries of Jupiter’s interior, including the planet’s magnetic field and the role that it plays in Jupiter’s overall structure and dynamics. Finally, the Juno spacecraft is also searching for evidence of a possible subsurface ocean on Europa, which could potentially harbor life.

What happened during the flyby?

During the flyby, Juno made its closest approach to Jupiter’s moon, Europa. The spacecraft came within about 2,700 miles of the surface of the moon, making it the closest flyby of any spacecraft to date. Juno collected data about the moon’s environment and took pictures of its surface.

What does the data from this flyby tell us about Europa?

On Monday, October 19, NASA’s Juno spacecraft made its closest flyby of Jupiter’s moon Europa. The spacecraft collected a wealth of data during the flyby, and scientists are still working to analyze all of it. But what does the data from this flyby tell us about Europa?

For starters, the data tells us that Europa is a very active world. The spacecraft observed numerous geysers erupting from the moon’s surface, shooting material high into space. This activity indicates that Europa has a surprisingly warm interior, which is likely due to tidal heating from Jupiter’s gravity.

The data also reveals that Europa has a thin atmosphere made up mostly of oxygen and nitrogen. This atmosphere is thought to be created by water vapor escaping from the moon’s interior through its many cracks and fissures.

Lastly, the data shows that Europa has a strong magnetic field. This field protects the moon from Jupiter’s radiation belts, making it a potential habitability for life as we know it.

Overall, the data from Juno’s flyby of Europa provides us with valuable insights into the nature of this intriguing moon.

What are the next steps in exploring Europa?

The next steps in exploring Europa are to continue to study the data collected by Juno and to plan for future missions. Juno has provided scientists with a wealth of new information about Jupiter and its moons, and there is much more to learn.

Future missions could include a spacecraft that would orbit Europa and study it in more detail, or a lander that would touch down on the surface and analyze the composition of the ice. These missions would help us to better understand Europa and whether it could be habitable for life.


The Juno spacecraft has just made its closest flyby yet of Jupiter’s moon, Europa. This is a big deal because Europa is one of the most promising locations in our solar system for life as we know it. The flyby gives us a chance to take a closer look at this fascinating world and see if there might be anything living there. So far, the signs are looking good.
