Anyone who has ever worked on a team knows that their strength lies in coordination and a shared vision. However, it is not always easy to provide that coordination and shared vision, and any team that lacks that cohesiveness becomes more of a hindrance than a help.
Science is not immune to the difficulties of running effective teams. There is plenty to be gained from more coordination between differing silos and physical locations. Recently a meeting in Chile prompted a group of scientists to propose a plan to change that. The result is a white paper that points out the potential benefits of coordinating ground, orbital and in situ based observations of objects. But more importantly, it suggests a different path forward where all of the space science community can benefit from the type of coordinated output that can only come from a cohesive team.
On July 5, 2016, NASA’s Juno spacecraft arrived around Jupiter, becoming the second mission in history to study the gas giant from orbit – the last being the Galileo spacecraft, which orbited Jupiter from 1995 to 2003. Since then, the spacecraft has gathered data on Jupiter’s atmosphere, composition, gravity field, and magnetic field in the hopes of learning more about how the planet formed and evolved.
In addition, the spacecraft has gathered some of the most breathtaking images ever taken of Jupiter and its system of moons. In fact, as the spacecraft was making another approach towards Jupiter on December 26th, 2019, it managed to capture the first infrared images of the moon Ganymede’s northern polar region. These images will inform future missions to this satellite, which could host life beneath its icy mantle.
There’s a new storm brewing on Jupiter. The most famous storm on Jupiter is the Great Red Spot, which has been active since at least the time of Galileo. Most of Jupiter’s storms don’t last for hundreds of years. They grow and fade just as they do on Earth. This latest storm was discovered by amateur astronomer Clyde Foster.
It’s difficult to imagine the magnitude of storms on Jupiter. The gas giant’s most visible atmospheric feature, the Great Red Spot, may be getting smaller, but one hundred years ago, it was about 40,000 km (25,000 miles) in diameter, or three times Earth’s diameter.
Jupiter’s atmosphere also features thunderheads that are five times taller than Earth’s: a whopping 64 km (40 miles) from bottom to top. Its atmosphere is not entirely understood, though NASA’s Juno spacecraft is advancing our understanding. The planet may contain strange things like a layer of liquid metallic hydrogen.
Now a group of scientists are combining the power of the Hubble Space Telescope, the Gemini Observatory and the Juno spacecraft to probe Jupiter’s atmosphere, and the awe-inspiring storms that spawn there.
Artist Mik Petter has created a vibrant new piece of art based on JunoCam images of Jupiter’s Great Red Spot (GRS). The piece makes use of fractals, which are recursive mathematical creations; increasingly complex patterns that are similar to each other, yet never exactly the same.
Though it looks like it to us, Jupiter’s clouds do no form a flat surface. Some of its clouds rise up above the surrounding cloud tops. The two bright spots in the right center of this image are much higher than the surrounding clouds.
In a death-defying maneuver for the spacecraft, NASA’s Juno has completed an unprecedented and unplanned engine burn. The purpose? To save the spacecraft’s “life,” or at least the rest of its mission to Jupiter.
Jupiter casts a deep, dark shadow. Dark enough, in fact, to effectively kill Juno if it flies through it. Rather than let the spacecraft spend 12 battery-draining hours in Jupiter’s shadow, and then attempt a risky resuscitation on the other side, NASA took another course of action: a 10.5 hour burn of Juno’s reaction thrusters that will steer it clear of Jupiter’s life-draining shadow.
The JunoCam onboard NASA’s Juno spacecraft continues to provide we Earthbound humans with a steady stream of stunning images of Jupiter. We can’t get enough of the gas giant’s hypnotic, other-worldly beauty. This image of Io passing over Jupiter is the latest one to awaken our sense of wonder.
This image was processed by Kevin Gill, a NASA software engineer who has produced other stunning images of Jupiter.
There’s something about Jupiter that mesmerizes those who gaze at it. It’s intricate, dazzling clouds are a visual representation of the laws of nature that’s hard to turn away from. And even though the Juno spacecraft has been at Jupiter for almost three years now, and has delivered thousands of images of the gas giant’s colourful, churning clouds, we can’t seem to satisfy our appetite.
Thanks to a mission extension, NASA’s Juno probe continues to orbit Jupiter, being only the second spacecraft in history to do so. Since it arrived around the gas giant on July 5th, 2016, Juno has managed to gather a great deal of information on Jupiter’s atmosphere, magnetic and gravity environment, and its interior structure.
In that time, the probe has also managed to capture some breathtaking images of Jupiter as well. But on December 21st, during the probe’s sixteenth orbit of the gas giant, the Juno probe changed things up when four of its cameras captured images of the Jovian moon Io, showcasing its polar regions and spotting what appeared to be a volcanic eruption.
