| Feb 8, 2015 at 9:43 | comment | added | Eric Platon | "One might think that spacecraft would be on the cutting edge of technology." I'm guilty of wanting more "Star Wars"-like future and less "2001". But no one hears you scream in space... Excellent question +1 | |
| Aug 17, 2013 at 12:17 | comment | added | nos | nasaspaceflight.com/2013/07/… is te story on them starting to build the Flight Computer for the SLS , now in 2013. So everything has been selected for use. Imagine how we'll think it's outdated when the SLS becomes operational. Or a decade into its operation. | |

returned title to its original statement

| Aug 7, 2013 at 15:16 | comment | added | GreenMatt | @Donald.McLean: When the example I was referring to was launched, 32 bit processors were normal for desktop systems. As for Chad's point, when Pentiums were the standard processors in desktops, most people considered 8086's to be obsolete; furthermore, I didn't ask "Why don't spacecraft use cutting edge data systems?" | |
| Aug 7, 2013 at 4:56 | comment | added | Donald.McLean | @GreenMatt My point is that you made a clear and specific statement "32 bit processors are the commercial standard." and I am disputing that statement. Yes, it seems bizarre that many spacecraft are launched with outdated CPUs. In 1999, SM3A replaced the original Hubble computer with a 486 (six full years after the Pentium was released). However, Chad's point is still valid. | |

| Aug 6, 2013 at 21:18 | comment | added | GreenMatt | @Donald.McLean: True, but that was just an example (which I had some first hand knowledge of and which surprised me when I learned about it). | |
| Aug 6, 2013 at 16:55 | comment | added | Donald.McLean | Actually, most desktops (and even many laptops) are now 64 bit systems. | |

| Jul 21, 2013 at 12:11 | comment | added | GreenMatt | @Chad: True, but an 8 bit processor is ancient when 32 bit processors are the commercial standard for desktop systems. | |
| Jul 21, 2013 at 4:41 | comment | added | Chad | not cutting edge != obsolete. | |
