This is our library of documents related in some way to the spaceborne computer systems of space probes and satellites. Or more generally, spaceborne computers for which we usually do not have any flight software, and hence no motivation yet for spending effort on creating standalone web-pages or development tools like assemblers, compilers, or CPU emulators. Get us the software for these computers! Our other libraries are: To avoid clutter on your screens, some details we have — download size, archive from which the digitization was made, name of the person who scanned the document or financially subsidized it, the organizational affiliations of the authors, the organizations which assigned the document numbers — are omitted from the entries for the documents. You can get this kind of information anyway, should you desire it, by hovering the mouse cursor over the document title, author name, or document number. Notice the styling that's used to call your attention to the availability of the extra information; authors' names or document numbers without extra information available are not thusly highlighted.

Unless otherwise stated, documents are sorted by publication date, from earliest to latest, and those with unknown dating appear at the top of the list. Determination of the publication date is sometimes rather subjective.

Finally, this page is auto-generated from a database — actually a spreadsheet — and if you desire, you can download the spreadsheet. (In pulling it into your spreadsheet program, you mostly need to know that the columnar data is tab-delimited. There's actually a full explanation here, but I can't imagine you'll want to read it.)

Hubble Space Telescope

See the Wikipedia article.

Viking Mars Orbiter and Lander

See the Wikipedia article and "Viking Computer Systems" in Tomayko's Computers in Spaceflight.

Each of the Viking 1 and 2 missions consisted of a Mars Orbiter and a Mars Lander, and each of these had an onboard computer system:

Voyager Space Probes

See the Wikipedia article. and Chapter 6 of Tomayko's Computers in Spaceflight.

The Voyager 1 and 2 space probes each had 3 onboard dual-redundant computers: Numerous online sources state that the flight software was written in Fortran 5, then later ported to Fortran 77, and still later ported somewhat to C. Such claims are all erroneous. Rather, all flight software was written in the respective assembly languages.

I must say, this seems to be a peculiar division into "volumes", with Volume III containing document sections 4.1 through 4.7 and Volume IV containing section 4.8, and that table of contents for both appearing in Volume III. But what do I know?
