Solar System: Things to Know This Week

Solar System: Things to Know This Week

Follow our Juno craft during a close flyby of Jupiter, learn about Cassini’s final mission during a Facebook live event (in case you missed it) and more!


1. Jupiter, Up Close

Our Juno mission completed a close flyby of Jupiter on Thursday, February 2, its latest science orbit of the mission. All of Juno’s science instruments and the spacecraft’s JunoCam were operating during the flyby to collect data that is now being returned to Earth. 


Want to know more? Using NASA’s Eyes on the Solar System and simulated data from the Juno flight team you can ride onboard the Juno spacecraft in real-time at any moment during the entire mission.


2. In Case You Missed It–Cassini Facebook Live

Cassini Project Scientist Linda Spilker and mission planner Molly Bittner take questions about the mission’s “Ring-Grazing” orbits during Facebook Live. Watch it now:


3. Cassini Scientist for a Day Essay Contest 

The deadline is Friday, February 24 for U.S. student in grades 5 to 12. For international students, visit the page for more info! 



4. Cassini Spies Dione

Dione’s lit hemisphere faces away from Cassini’s camera, yet the moon’s darkened surface are dimly illuminated in this image, due to the phenomenon of Saturnshine. Although direct sunlight provides the best illumination for imaging, light reflected off of Saturn can do the job as well. In this image, Dione (698 miles or 1,123 kilometers across) is above Saturn’s day side, and the moon’s night side is faintly illuminated by sunlight reflected off the planet’s disk.
