Aerospace Research in a post NTRS world

Since late March 2013, the NASA Technical Reports Server, NTRS, has been off-line. This represented the loss of a significant resource for aerospace research, here is some information to help access some of the missing documents.

How To Find Papers

All this information was obtained from the blog of the Web Science and Digital Libraries Research Group

NACA Reports

NASA Reports

  • Some post 1958 NASA reports are located in the internet archive’s NASA Techreports Collection.

    • To use this, perform and advanced search and choose the collection nasa_techdocs
  • The University of North Texas has a large collection of NASA reports.

    • Submit an Inter-Library loan request according to the instructions here

RAE Reports

  • Older reports from the Royal Aeronautical Society can be found at another Cranfield University website

The Memento Protocol

  • All previous versions of the NTRS website have been archived by the Memento project. Iff you know the exact URL of the pdf you are looking for, you can find view a version of the page from before 2013.

    1. Install firefox and add the MementoFox
    2. Use google scholar to find the exact article you are looking for. To the right of the citation there should be a link to the NASA website.
    3. Click this link, it will take you to a 404 error.
    4. Copy the address in from the address bar and use memento fox to view the page before March 2013
    5. The article should be visible.
  • This process is a bit time consuming as the Memento Protocol takes a while to access the old data.

  • This process will only work so long as google links to the dead NTRS pages

Questions and Answers on NTRS

Background

On March 20, 2013, the NASA Administrator directed that the NASA Technical Reports Server (NTRS) be taken off-line while the Agency conducted a review of whether there is a risk of export-controlled documents being made available on the NTRS website. During this review, NASA provided the following public notice:

"The NASA technical reports server will be unavailable for public access while the agency conducts a review of the site's content to ensure that it does not contain technical information that is subject to U.S. export control laws and regulations and that the appropriate reviews were performed. The site will return to service when the review is complete. We apologize for any inconvenience this may cause."

Across the succeeding weeks, teams of personnel from the NASA Center for AeroSpace Information (CASI) and NASA Scientific and Technical Information Program Office (STIPO) have validated approximately 966,460 documents and metadata records from the NASA Technical Reports Server (NTRS) to ensure that all have received proper review and approval for public release, including required export control reviews for those NTRS records that comprise scientific and technical information. NASA is continuing to review a smaller subset of documents, which will be loaded to the NTRS once the review is completed.

Responses to Questions

  1. Why was the technical reports server taken down?

    • The NASA Technical Reports Server was unavailable for public access while the Agency conducted a review of the site’s content to ensure that the appropriate reviews were performed and that it does not contain technical information subject to U.S. export control laws and regulations.
  2. Why has NASA now brought the technical reports server back-up?

    • The NASA Technical Reports Server is returning to service following the review and confirmation of approximately 966,460 records, images, and documents as having been properly screened and certified for public release.
  3. How many records have been reviewed and certified for posting on the technical reports server? How many have yet to be reviewed and certified for return to the technical reports server? When will they be posted?

    • The NASA Technical Reports Server will contain more than 966,460 records, images, and documents for public research purposes. A subset of approximately 248,000 documents, largely consisting of older documents, including National Advisory Committee on Aeronautics (NACA) materials, remain to be reviewed, and they will be loaded back to the NASA Technical Reports Server as soon as the reviews are completed by the originating NASA Centers.
  4. Has NASA asked the State Department to review all or any of the documents on NTRS for ITAR content?

    • NASA has notified the State Department of matters regarding NTRS and provided specific documents it has requested to review.
  5. Were any documents removed from NTRS as a result of the review? If yes, how many and why are they not being reloaded on NTRS?

    • Approximately 248,000 documents were removed from the NASA Technical Reports Server that will not be reloaded at this time. These documents require additional review to ensure that they do not contain technical information that is subject to U.S. export control laws and regulations.

Other Information

  • The 248,000 documents removed from NTRS represent 85% of the full text reports from the original NTRS. More information here
