Operating systems used in spacecraft?

It's COTS if I can order it from Digi-Key and have it arrive on my desk the next morning. :-) Actually, you can take the ":-)" off that. One of the Secret Wisdoms :-) of the cheap-spacecraft mafia is that prototyping early and often, which is really good for effective debugging and thus for system reliability, is just a Whole Lot Easier if you stick to parts that *don't* have six-month delivery times and a requirement for ITAR paperwork. (Not to say that these necessarily do; haven't tried them.) Being able to implement your design change tomorrow, so you can start testing it the day after, does wonders for cost-effective engineering. -- MOST launched 30 June; first light, 29 July; 5arcsec | Henry Spencer pointing, 10 Sept; first science, early Oct; all well. | |
