We used to toy around at 700-750ms latency, when running off of
satellite. Crypto up, transit time, processing time, transit time down,
decrypt, rinse and repeat for the other end.
Could you picture something like that to the moon with TCP?  ;)

More seriously though, NASA did come up with something, didn't bother
checking into what the protocol they were using was, but it had
excellent bandwidth and was designed for latency of seconds or more.
Now, if we ever return to the moon, the astronauts will at least manage
to have decent connectivity.
Pity that Congress finds it more important to buy new and improved
howitzers instead of investing in space exploration and exploitation.
