Yes, it did. I like the sentiment but I wonder how much conflict of interest would undermine this idea. Imagine how many companies are involved in developing space grade one-off hardware! Also, why would a highly bureaucratic structure undercut the amount of money that they themselves are asking for (and receiving) out of a budget? Savings are not aligned with the interest of such structure. Its not that for the amount you have saved you can allocate rest of the funds for something else (usually this is how it works with publicly funded projects AFAIK)

Every bit of money and platform resources (rad hardened CPUs are giant, slow and power inefficient compared to even semi modern COTS) is money and resources that NASA can spend on scientific payload on the same platform.

NASA absolutely does have some incentive to find savings in control hardware and software.

Finally, while Ingenuity does use a non-hardened Snapdragon, many other of its critical electronics components are still rad-hardened. The FPGA and dual MCUs (that actually do the low level control and I/O I assume) are both rad hardened. In addition, the COTS components that were used where screened by NASA for their performance in radiation.

The Snapdragon is really just there to control the radio, and do image processing. Critically, these are functions that have -some leeway- for timing, giving the option to just restart the Snapdragon if a watch dog detects a problem.

All of this to say is that rad-hardening isn't going away, but will probably stick around in many critical niches. What Ingenuity absolutely do is validate that modern COTS processors have a role to play in radiation elevated environments, including in semi-critical applications.

This is a great and informative comment!

HN is dominantly a web/SW crowd plus some mobile frontend, and "it uses a Snapdragon" gives many a wrong idea. In embedded device projects a lot of time is spent planning and designing around a heavy compute element running Linux like this, especially if the device has a safety concept or other mixed criticality concerns. It will have a substantial moat around it.

On HN if you say "systems architecture" most folks go "Oh you mean like, whether we use microservices?". In embedded, while there is a lot of overlap and analogues, it's also all of the above, plus power state management and other aspects. It's not very shiny, but that profession makes all your cars, airplanes and alien planet multicopters.

"It's not very shiny, but that profession makes all your cars, airplanes and alien planet multicopters."

If you have a good head for it, it's a pretty darn good career. You might not make $500k/year like you would at google, but the money is still decent and reliable.

Plus, working on spacecraft is cool as hell.

This also drops the bar for other space agencies, from other countries and private alike. Getting cheaper hardware also means more launches and more testing. Instead of sendind a multi million project to space, you can send basically a smartphone (an epheumism, ofc) and some big antennas, and do it in bulk

Well maybe they could start doing bigger and better missions, if they can reliably pull it off.
