Keith's note: Have a look at the Aerospace Research Information Center in South Korea. Do a few searches and you will see all sorts of NTRS material is hosted there. This makes things much easier for the folks in North Korea to access, one would assume. It has been there while NTRS was offline.

Meanwhile NTRS is apparently back online - for now. According to NASA sources, based on an analysis of the NTRS collection before it was taken offline and now brought back online, it is apparent that over a quarter of a million full-text NASA reports are no longer in NTRS. This missing set of data represents a full 85% of the NASA full-text reports. In addition, only 7% of the historical (but still technically relevant) NACA collection remains online (only about 1,000 of the roughly 14,000 that comprise the NACA collection).

Of course, NASA's response to all of this is to gut the staff of CASI, the contractor responsible for maintaining NTRS. Can NASA review and reload the missing quarter million reports? Will NASA be able to add new reports into the NTRS (and NA&SD) collections?

Having used NTRS for our Lunar Orbiter work at LOIRP I just did a quick check to see if some of the 45 year old documents I have downloaded from NTRS are still online. Guess what: these documents are no longer online. You can buy hard copies on eBay (as I have done) I wonder what sort of security risk these documents pose such that Charlie Bolden has taken them offline?
