I’m Anthony Colangelo.

And here’s the megafeed of everything I’ve been doing.


Main Engine Cut Off

The Moon 2024 initiative finally has a name, and it kicks ass—Artemis. However, there seems to be some mass cognitive dissonance surrounding all this that I can’t get my head around.

I Built a Mac App

Downlink MacBook Pro

While most everyone has been trying to figure out what the deal is with Marzipan, I decided to learn (a very tiny amount of) AppKit and built my first Mac app.

It’s called Downlink, and it brings real-time satellite imagery of Earth right to your desktop. You can get it today—for free!—on the Mac App Store.


Dot First

Downlink MacBook Pro

Real-time satellite imagery on your desktop.

Watch sunlight and weather patterns move across Earth throughout the day, and bask in the glory of our blue marble in real time.

Every 20 minutes (or every hour, you pick), Downlink updates your desktop background with the newest images of Earth.

Choose from 8 different views of Earth, including stunning full disk images from 3 different geostationary satellites.

Episode T+119: Dr. John Charles

Main Engine Cut Off

Dr. John Charles spent nearly 33 years at NASA—most recently as Chief Scientist of the Human Research Program—working on human spaceflight through Shuttle, Mir, ISS, and beyond. He lead missions such as STS-95 (John Glenn’s Shuttle flight), STS-107, and the Twins Study with Scott and Mark Kelly. He retired from NASA in February 2018 and is now the Scientist in Resident at Space Center Houston. We talk about his career, the human spaceflight issues he worked and solved in his time at NASA, and the things that need to be solved for the exploration of the Moon, Mars, and beyond.
