Low-cost, short lifespan satellites made of COTS parts seem like a great idea, but aren't launch costs still enormous?

DoD spent billions to build something close to smart phones but never got close. And guess what? These things are already here, without a dime of public money! Anyway add a few accessories, smart phones will make good micro or nano satellites. Radiation will be problem that will shorten the service life. But given almost weightless and almost free of cost you can afford lot of redundancy.

They probably expired due to tin whiskers forming because the phones are manufactured with lead free solder. :-(

Add a nice camera and the military will be able to spy on other places around the world and cover large areas per picture when there are multiple units working together. I also wonder about security, Android is not impregnable and a hacker just might call up and get access. Things to think about. Sometimes non-commercial systems make better sense.

Interest idea but limited use in current forms ... this can be considered an incremental update for preliminary demonstration purposes ... As always, serious engineering needs to be done for real Space products that work 24/7 for years on end.

Crowdsourced debugging - an interesting paradigm shift. Rather than spending a fortune in development and testing of a one time use system, select a system that has been used by millions and is known to work. Were any modifications required for vacuum and space temperature conditions? Interestingly, those very changes would introduced the greatest risk of an unexpected failure since they were untested byb the "crowd".

I was wondering about the temp and vacuum conditions on the interconnects? I would be very curious to see how they put a standard smartPhone into low / middle earth orbit and have it work. I think that this is a very exciting development and would love to see high school/college satellite projects get some payload space on future launches. What a great way to encourage students in STEM related areas and promote space!

The DoD has ben discovering this phenomenon for many years now, applying commercial off the self components in many, many systems. Computers are the most obvious example of COTS content. It shouln't surprise anyone that the migration from military-specific mainframes, of the 1970s and early 1980s, to commerial PCs in the mid 1980s to today, would move on to commercial smartphones. I would expect that for space applications, you have to do someting to defend against radiation. Not sure how long a commercial smartphone would last out there. I'll bet, not as long as the Voyager spacecraft have been working!!
