Why nasa use gmail?

sandworm101•1d ago
Better spam filters. Easier to block all the crazy people. Easier to hand over basic filtering to unpaid interns who dont yet have government logins/email accounts.
AStonesThrow•1d ago
They may all be unpaid for this; copyright belongs to one man rather than being a work of the US government. It looks like a project from their spare time and retirement.
sandworm101•1d ago
With a nasa.gov domain, it is most likely a former nasa employee.
AStonesThrow•1d ago
There is this thing that webmasters can do called "hosting" where they give access to other people to store and distribute their work.

This is a collaboration and international labor of love, with people hailing from Australia, England, and Canada. Go visit nasa.gov at top-level and see how the design changes, and the NASA logos are used.

These pages carry the Apollo insignias, and "last modified: November 2017".

Hello. NASA person and contributor to the ALSJ here. This is a volunteer effort that is one of the oldest websites on the internet (and most awesome). The original transcripts are public domain, but the commentary here is what’s under some copyright. That said, it’s online for the greater good. I hope you enjoy it.
nancyminusone•1d ago
>The corrected transcript, commentary, and other text incorporated in the Apollo Lunar Surface Journal is protected by copyright.

If this is a government document, how is it not public domain? If it's not a government document, why is it hosted on a .gov?

thejarren•1d ago
This is a fan edited compilation. The original raw source docs are public domain, but this is a 3rd party website.

I like the old skool anti-spam bot filter attempt of making it an image instead of text.

vertnerd•1d ago
I discovered this site about 20 years ago, and it appears to be as good as ever. The volume of detailed documentation here is all you need to dispel fantasies about a moon landing hoax.
