Linking to a NASA document as a reference in an answer or a question is at the moment complicated by the fact that they seem to have a bunch of expired security certificates for their websites. I think that makes this on topic here. The issue doesn't show up unless you try to access the sorts of documents that are deeper within the system. Here are two I just ran into:
That one was for their Trajectory Browser page, a very useful tool.
That one was for the Space Settlement Design Study table of contents, a classic document. I have also run into this over the last week for documents hosted at KSC, Johnson, and SSERVI.
I briefly started looking for the place to try to contact someone to alert them to this issue, but gave up after a few minutes. There must be a much more targeted way to contact them about this than the general emails and phone numbers I can find on the websites. I have a feeling I could spend a long time doing it that way and not get to the person who could really do something about this.
I used to look for an alternate source of the information I was after when I ran into this problem with NASA (I have run into the issue repeatedly over the last year). I wasn't sure if it might mean they had been hacked. The notice is pretty extreme, so I decided not to risk it.
Does anyone have a tip for how I might more quickly get to someone who can do something about this problem?
