Juno spacecraft to remain in same orbit, but science observations of Jupiter continue

NASA’s Juno spacecraft has been orbiting the gas giant planet Jupiter since July 4, 2016, and has already greatly increased scientists’ understanding of this fascinating world, the “King of Planets.” For the past while now, Juno has been in an elongated 56-day orbit, which brings the spacecraft close in over the cloud tops before swinging out farther away from the planet again. The plan had been for Juno to then switch to a closer, 14-day orbit, but due to growing concerns over another engine burn possibly resulting in a less-than-desirable new orbit, that plan has now been scrapped. Juno will now remain in its current orbit for the remainder of the mission.

The Juno spacecraft has sent back a beautiful new view of Jupiter’s “Little Red Spot,” a smaller and paler version of the Great Red Spot, which is an anticyclone in the atmosphere (a large-scale circulation of winds around a central region of high atmospheric pressure). Other complex cloud patterns can also be seen. The image was first taken on Dec. 11, 2016. The amazing full image is below:

As reported a few days ago, the Juno spacecraft orbiting Jupiter had entered safe mode, a precautionary turning off of all but vital instruments and other components when a software performance monitor induced a reboot of the spacecraft’s onboard computer. Now, Juno has successfully exited safe mode and is otherwise healthy and ready to continue its exploration of Jupiter.

NASA’s Juno spacecraft has been busy orbiting Jupiter and providing fantastic new views of this giant world, something not possible since the previous Galileo mission. While almost flawless so far, the mission has had a few hiccups recently. Juno entered safe mode just shortly before its next close flyby of Jupiter this week, apparently the result of a software performance monitor inducing a reboot of the spacecraft’s onboard computer. The spacecraft is otherwise healthy and Juno is conducting its own software diagnostics to determine the specific cause of the problem. Before this, Juno took its first observations deep into Jupiter’s turbulent atmosphere.

The Juno spacecraft orbiting Jupiter has been sending back some beautiful new views of Jupiters north and south poles, not seen before in detail until now. This is still very early in the mission and there will be many more and better ones to come! The intricate swirls of storms and other clouds make the polar regions distinctly different from the banded equatorial and mid-latitude regions which we are used to seeing. Thanks to Matt Brealey for the use of his processed NASA images. More of his work is on his blog The State of Space.

NASA’s Juno spacecraft enters orbit around Jupiter, the ‘King of Planets’

Jupiter has often been referred to as the King of Planets, and for good reason, as it is a massive gas giant, much larger than Earth and the largest planet in our Solar System. It is more than 2.5 times as massive as all the other planets combined, and is a mesmerizing world of colourful bands of clouds wrapping around the globe, which can be seen even in a small telescope, but exhibit incredible detail when seen by spacecraft. Jupiter is also itself the center of a sort of miniature solar system, with dozens of moons orbiting around it. We’ve seen this world up close before by spacecraft such as Voyager and Galileo, but now a new visitor has arrived in the Jovian system: NASA’s spacecraft Juno.
