Downlink on a MacBook Pro.


Real-time satellite imagery on your desktop.

Download on the Mac App Store

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

Thank You

Thanks to NASA, NOAA, JMA, Lockheed Martin, Harris Corporation, ULA, MHI, and everyone else who designed, built, launched, and operate GOES-16, GOES-17, and Himawari-8.

If you’d like to use the sources Downlink is built on top of, here is the file pointing to those resources. Use it, and tell me what you’ve built!

If you enjoy my work on Downlink, I also write and podcast about all things space over at Main Engine Cut Off.

Other Views, Europe, & Africa?

As new sources come online, they’ll be added to the app as fast as possible.

As of yet, though, I haven’t been able to find an open and available data source for Europe and/or Africa with the image quality and refresh frequency needed.

If and when one is available, it’ll be in the app.
