Identify minicomputer/tape drive for NASA tape reels?

Hi,
I’ve come across a fairly large collection of tape reels containing copies of NASA satellite data (Dynamics Explorer 1 and another satellite), the copies look to be from the mid to late 80s. What are some identifying features I should look for to figure out the tape drive and minicomputer needed to read them? They’re taking up a lot of space and it would be nice to move the data to something more modern.

Are they 1/2" tape reels? Something else? Further description or pictures would help.

First impression is that they're talking about instrumentation recorders.

I can take photos in a couple days, but they look like 8 or 9 track tape reels. They are copies of instrument data with some processing.
