Happy Friday! Hope you feel good! This week:

We’ve learned the Cassini Saturn orbiter is going to go into its “grand finale” stage of its mission later this year. But fear not, because Gizmodo has this look back at some of Cassini’s greatest images.

This week also brings us news of this awesome robot inspired by the manta ray! With its soft body made of a flexible polymer and silicone, this bot can swim with the fishes without harming them!

This week also brings us news of the discovery of this 3,700-year-old pyramid, thought to be the remains of one of the first attempts to make a smooth-sided pyramid!

What’s making you happy this week? Let us know in the comments!
