The day I caught rocket fever

On February 6, 2018, I found myself shoulder to shoulder with two of my heroes: Bill Nye on the left, Buzz Aldrin on the right. Our eyes were fixed on the first vertical Falcon Heavy rocket.

Juno meets Cassini: A new merged global map of Jupiter

The Juno spacecraft that is currently orbiting Jupiter has obtained the first good images of Jupiter's polar regions. I am presenting here a combined global map of Jupiter, made from a Cassini map I made for the equatorial and temperate regions and polar maps made from the Juno JunoCam and JIRAM polar images.

Happy Monday! Here's a picture of Prometheus. You may think it's a picture of Saturn. Look hard, toward the bottom, and you'll see Prometheus, doing its part to keep the F ring in line.
