New Europa Pictures Beamed Home by NASA’s Juno spacecraft

Europa, Jupiter’s moon covered in ice, is still all it’s cracked up to be.

Juno, a NASA spacecraft that has been orbiting Jupiter since 2016, slid 219 miles from Europa’s surface early Thursday, speeding at more than 30,000 miles per hour.

Less than 12 hours later, the four images taken during the flyby, the closest observations of the moon since January 2000, returned to Earth.

Candice J. said: Hansen-Koharczyk, a scientist at the Planetary Science Institute in Tucson, Arizona, who is responsible for operating the spacecraft’s primary camera: “It’s really amazing,” JunoCam.

In its news release, NASA highlighted one of the images positioned in a region close to the moon’s equator, Annon Regio, showing long fractures that intersect the shiny icy surface.

The strange landscapes match what previous NASA visitors saw: the two Voyager spacecraft that flew through the Jovian system in 1979 and Galileo, which orbited Jupiter from 1995 to 2003.

The fractures indicated the possibility of an ocean on Europa, hiding under the ice, creating rifts through pressure from rising and falling tides. Other data in particular Magnetic field measurements refer to an electrically conductive layer Like the salty ocean, planetary scientists have convinced that the ocean is indeed flowing over Europa.

The presence of liquid water made Europe a promising place to search for life elsewhere in the solar system.

Juno flyby doesn’t change the story.

“I wouldn’t say there were some features that we were like, ‘Oh my God, this is new,'” Dr. Hansen Koharczyk said. “Instead, the new images provide a better view of certain parts of the Moon and help fill in the details.”

“We’ll be able to tell the kind of story of geological history better because you can connect different hills and fault lines and get a more global or regional picture,” said Dr. Hansen Koharczyk.

“I can’t say, ‘Oh, that one thing is amazing,'” she said. “Instead, there’s a lot of features that interest her.” It’s that kind of data. There’s a lot of complexity in Europe itself, and then these photos really showcase that.”

All four photos were available On Juno’s website. The originals have an orange-brown hue, but the moon will actually appear lighter in color. That’s because the camera was built into the space probe to attract audience participation and was not originally intended to be a scientific instrument. “We didn’t make an effort to do white balancing,” said Dr. Hansen-Koharczyk. “It’s by no means intentional.”

People all over the world immediately started Image downloading and optimization.

The images, along with other data collected by Juno, will help scientists plan for Europa Clipper, a NASA mission scheduled to launch in 2024 and make frequent flights close to Europa. It will also assist Jupiter Icy Moons Explorer, or JUICE, an European Space Agency mission due to launch next year that will study Europa and two other Jovian moons, Callisto and Ganymede.

Juno was launched in 2011 and reached Jupiter, the largest planet in the solar system, in 2016. It made frequent dives near Jupiter to allow its instruments to probe beneath the planet’s clouds. The one that revealed unprecedented lightning in the atmosphere and rain of baseball-sized conglomerates rich in ammonia. Scientists call mushrooms.

When the primary mission missions were completed last year, NASA approved an expanded mission for Juno, an additional 42 orbits of Jupiter that included close flybys of three large moons: Ganymede, Europa and Io.
