Jupiter se trouve à plus de 628 millions de kilomètres de la Terre. La sonde Juno, lancée le 5 août 2011, a atteint la planète le 4 juillet 2016. Il lui a donc fallu un peu moins de 5 ans, ou 1796 jours au total, pour arriver à destination.
Lundi 22 février 2021 ((rezonodwes.com))–Photos from the Perseverance rover, which landed on Mars last week, are getting all the attention. However, there are still plenty of other rovers and spacecraft working beyond the boundary of Earth’s atmosphere. Juno is coming up on the fifth anniversary of its arrival at Jupiter, and it’s still sending back stunning images.
NASA recently shared another image of Jupiter, beautifully displaying the planet’s jet streams. This one was color enhanced by citizen scientist Tanya Oleksuik using data from the JunoCam camera. The spacecraft originally took the image on December 30 during its 31st close flyby.
Data from the probe has allowed scientists to discover that these massive jet streams extend deeper into the planet than previously known. « Evidence from Juno shows the jet streams and belts penetrate about 1,800 miles (3,000 kilometers) down into the planet, » NASA said in the announcement.
Jupiter looks gorgeous in the new image, with just a glimpse of the Great Red Spot visible near the top. It makes the turbulent planet look like a delicately crafted marble.
