Kalileo Jool Orbiter has entered Jool Orbit

 Year 15, Day 112

After the launch of the Kalileo Jool Orbiter (KJO) earlier this year, it has finally arrived at Jool and plans to study and take pictures of the gas giant like never seen before.

Alongside pictures, of course, the spacecraft will also conduct close flybys of several of Jool’s moons, including Laythe and Vall, with a possible venture near Tylo. Scientists are eager to see the detailed images and data KJO will send back, especially after a nail-biting launch when fuel margins were almost too tight for even leaving Kerbin orbit. Now safely in Jool orbit, the mission team is optimistic about uncovering new insights into the planet’s atmosphere and cloud composition, magnetic field, and its moons.

First data sent back included stats about time, fuel left, energy, and estimated time for the RTG to die, which will be decades. We also now know for certain that Jool is made of mostly hydrogen and helium... however, we still do not yet know what causes it to be so green.

In fact, its first image of Jool upon entering orbit returned yesterday, and it's quite beautiful; take a look!
