i am familliar with the 78xx series, but i am a bit worried about the heat
output from such devices.

in a spaceraft, the heat will build up. i was wondering if there were some
other options.

There are a number of regulators available

78XX series, can drop, from memory 30V input down to 12, 9, 8, 5 as
standard, with just a few extra parts, ie, one capacitor.
