Anyone here ever used NASA JPL Horizons mainframe?

doing a bit of background learning (new role and all that) I was looking about for an IBM mainframe emulator and came across Hercules. Still figuring how to get it set up and running something like OS/360 but found I'll also need a terminal program, so loaded wx3270 and fired it up. It's default config seems to have a couple of ascii sites defined in the config, one being NASA Horizons. Clicked and it connected 😮

Now that's sparked my curiosity, anyone know if its allowed to access and what you can do there?

Looks potentially interesting

Don't select the play 'Global Thermonuclear War option' - doesn't end well

From the ever reliable https://en.wikipedia.org/wiki/JPL_Horizons_On-Line_Ephemeris_System

There are 3 ways to use the system and all of them can be automated:

Web (partial access)
Email (full access)
Telnet (full access)

https://ssd.jpl.nasa.gov/horizons/manual.html for v4

This is the web interface. https://ssd.jpl.nasa.gov/horizons/app.html#/

I assume you are using Telnet?

You can access to JPL space telescope data as anonymous so maybe / probably?

No idea how it connected but I'd guess it must be telnet given its an IBM 3270 terminal emulator and there's a DNS name pointing it at JPL. Sounds like an accidental find when looking to set up an IBM MVS/TSO emulator could add some interesting diversions on cloudy evenings then and don't worry, I won't take the Thermonuclear War option, might be no need soon anyway 😉
