Apollo and Gemini Computing Systems

Ronald Burkey writes:

Here you’ll find a collection of all the AGC, AGS, LVDC, and Gemini spacecraft computer documentation and software that I’ve managed to find whilst working on Virtual AGC. Every document on this page is archived here at Virtual AGC, regardless of whether it originated here or not. In the early days I used to include only material I uncovered by my own efforts, but there have increasingly been contributions by readers, including some of the original AGC developers. And there’s material here that has been duplicated from other Apollo-centric websites for your convenience; see the FAQ page for a list of the fine Apollo and Gemini websites I raided. Now, there is some value-added in this process, since I add searchable text to those PDFs which are image-only, as well as adding metadata and bookmark panes where they don’t exist. My intention is to eventually provide one-stop-shopping for all of your Apollo and Gemini computing-system documentation needs. Note however, that I choose to duplicate only scanned or photographic images of the original documents. In other words, I provide something as close to the “real thing” as I can. On some sites, notably the Apollo Flight Journal and Apollo Lunar Surface Journal, great pains have been taken to produce HTML forms of the documents. I do not duplicate those improved reformulations here, because that’s original work for which I think credit is due; so you will have to visit those sites to use those improved versions.

Awesome data set!

OK, I admit to a bit of nostalgia because I grew up watching these and earlier space flights.

Indexing and mapping the terminology of these documents would make an interesting project.

To say nothing of comparing the terminology here to later space efforts.

IRODS

IRODS:Data Grids, Digital Libraries, Persistent Archives, and Real-time Data Systems

From the website:

iRODS™, the Integrated Rule-Oriented Data System, is a data grid software system developed by the Data Intensive Cyber Environments research group (developers of the SRB, the Storage Resource Broker), and collaborators. The iRODS system is based on expertise gained through a decade of applying the SRB technology in support of Data Grids, Digital Libraries, Persistent Archives, and Real-time Data Systems. iRODS management policies (sets of assertions these communities make about their digital collections) are characterized in iRODS Rules and state information. At the iRODS core, a Rule Engine interprets the Rules to decide how the system is to respond to various requests and conditions. iRODS is open source under a BSD license. (emphasis in original)

Provides an umbrella over data sources to presents a uniform view to users.

The rules and metadata don’t appear to be as granular as one expects with topic maps.

I mention it here because of its use/importance with space data and as a current research platform into sharing data.

Questions:

  1. Current and annotated bibliography for the project.
  2. What are the main strengths/weaknesses of this approach? (3-5 pages, citations)

Consultative Committee for Space Data Systems (CCSDS)

Wednesday, September 22nd, 2010

Consultative Committee for Space Data Systems (CCSDS) is a collaborative effort to create standards for space data.

Interesting because:

  1. Space exploration get funding from governments
  2. Subjects for mapping in a variety of formats, etc.

Assuming that agreement can be reached on the format for a mission, the question remains how do we integrate that data with articles, books, presentations, data from other missions or sources, and/or analysis of other data?

That agreement is reached on a format for one mission or even one set of data, is just a starting point for a more complicated conversation.
