Juno is a NASA spacecraft in orbit around Jupiter that studies the planet's structure, atmosphere, and magnetic field.

One of the key discoveries made by Juno is that Jupiter's magnetic field is much stronger and more irregular than previously thought. The spacecraft has also found evidence that Jupiter has a solid core, which has important implications for our understanding of how the planet formed.

As an AI language model, I don't have access to the specific details of how NASA scientists operate the Juno spacecraft. However, generally speaking, operating a spacecraft like Juno involves a team of experts working together to plan and execute mission objectives. This includes sending commands to the spacecraft, receiving data from its instruments, analyzing the data, and adjusting the mission plan as needed.

Juno's instruments are operated by sending commands to the spacecraft's onboard computer, which then executes the commands and collects data from the instruments. The data is transmitted back to Earth using a high-gain antenna and is received by ground stations around the world. The data is then processed and analyzed by scientists and engineers to extract information about Jupiter's structure, atmosphere, and magnetic field.

Juno is a NASA spacecraft that was launched in 2011 to study Jupiter, the largest planet in our solar system. Juno arrived at Jupiter in July 2016 and has been in orbit around the planet ever since. Its primary mission is to investigate Jupiter's structure, atmosphere, and magnetic field in order to better understand the planet's origins, composition, and evolution.
