This might not be noticeable right away, but we don’t fly a directional antenna on our missions. We have the ability to, but directional antennas add mass, something we want to minimize as much as possible. We fly omnidirectional antennas. They’re smaller, and they also allow us to talk to the planet when we are under continuous thrust from our Hall-effect thrusters. The cost? Well, it’s steep. At our max range, 20 million miles from the planet, our link is 120 bits per second. Normal data protocols don’t even work. We’re talking in the same domain as Voyager: slow. It drives all the decisions on data and tactics we use to rewrite the way we explore. We already have a number of mission in the pipe that will require a directional antenna for data, but this one, our core mining mission, will not.

Happy to release Maia SDR, an open-source FPGA-based SDR project focusing on the ADALM Pluto. This first release can display the waterfall on a web browser using WebGL2 and record in SigMF format, at up to 61.44 Msps. Here is a short demo, and some technical details. 🧵

KiCad is a free, open source suite of CAD tools for schematic capture and Printed Circuit Board (PCB) design. We really like it, so we've made a newer version available on Raspberry Pi OS. We're also helping KiCad with their end-of-year funding drive. raspberrypi.com/news/support…

New blog post: Connecting the Pluto SDR to an Android phone. Here I explain the steps that I've had to follow to make Ethernet over USB work (basically switch from RNDIS to ECM), and how the Linux USB gadget support is configured and can be debugged. destevez.net/2022/09/connect…

The prestige attached to complexity means it requires a real commitment to make things simple. Not only do you have to do more work, but people will be less impressed with you for it.

If you're trying to decide between two subjects to study and the one you're more interested in is also harder, it's probably the right choice.

Gives you a good feeling for the view on Mars
How’s this for 2020 vision? Over the holidays, I took a series of high-res photos of my hometown on #Mars. This panorama is made up of a crisp 1.8 billion pixels. It’s my most detailed view to date. Zoom in: go.nasa.gov/3ap38hB

Very cool thread, including discussion, pictures, and screenshots, of communicating with the DSLWP-B before it crashed into the surface of the moon.
