NASA launched Juno in 2011 on a mission to study Jupiter. succeed By sending back valuable data and stunning images of the largest gas giant in our solar system, Juno is now enjoying an expanded mission focusing on the planet’s moon rings and systems. NASA points out Juno. At the moon Ganymede recently and the spacecraft just sent some amazing photos.

Juno reached Jupiter in 2016, completing a highly eccentric orbit around the Earth. This allowed the probe to avoid being fried by Jupiter’s intense radiation belt. NASA also elected to keep the spacecraft in its underwear orbiting Jupiter 53 days early. due to engine problems Juno has been working fine since then. But no one wanted to risk losing their mission early on. And now we’re taking advantage of that warning with a fully functional Juno. It is now free to galavant around the Jovian system.

NASA is scheduled for Juno to fly over Ganymede on June 7, the first time a spacecraft has come close to a celestial body in more than 20 years. The last visitor was NASA’s Galileo spacecraft, which studied Jupiter. Between 1995 and 2003. In 2000, it flew past Ganymede, the largest moon in the solar system and the ninth largest object. as well as Europa and Enceladus. Scientists suspect Ganymede may have a subsurface ocean that could sustain life.

Juno flew past the moon at an altitude of 645 miles, close enough for JunoCam to capture nearly the entire hemisphere with green, blue, and red filters, allowing NASA to create true-color images of the enormous moon above. JunoCam Image It has a resolution of about 0.6 miles (1 kilometer) per pixel, but it offers sharper images from the Stellar Reference Unit, a navigation camera that helps the spacecraft stay on track. This camera is black and white. (Not a big problem for flat gray asteroids) and have resolutions between 0.37 and 0.56 miles (600 to 900 meters) per pixel.

The image shows the surface of the planet’s craters in stunning detail. There is also a long stripe that intersects the moon, similar to Europa’s Linea, without the distinctive color. Scientists speculate that the trough may be the result of intense gravitational tectonic activity from Jupiter, known as wave heat.

NASA only pulled a few images from Juno. More information will be provided in the coming days. All of which will be displayed on the project’s public repository for your viewing pleasure.
