A rep for NASA tells TMZ ... part of the resupply load, aboard a SpaceX capsule, that docked at the International Space Station Monday were thousands of pounds of cargo for scientific research -- and also some fresh grub.

We're told among some of the fresh food items -- which is a rare treat in space, since most everything is either freeze-dried or thermostabilized -- was a bunch of fruit. Sounds basic, but in space ... even a first bite at the apple is something to savor for these expeditions.

Some of that produce included Gala apples, navel and blood oranges, mandarin oranges, and ... lemons!!! Hey, when life gives 'em to you, gotta make the most of it right???

We're told there were also some holiday-themed hot foods sent up as well -- which are all probably arriving in some type of airtight packaging, a la Tang.

Among that lot, NASA says it shipped stuff like cherry blueberry cobbler, cornbread dressing, cranapple dessert, jellied cranberry sauce, macaroni & cheese, potatoes au gratin, roasted turkey, shortbread cookies, southwestern corn, sparkle gel, spicy green beans, french vanilla cappuccino and wheat flatbread. Mmmm -- space munchies 😁.

BTW, these are the same astronauts that were shot up into the sky a few short weeks ago in another SpaceX Dragon capsule. So, they're probably due to a fresh shot of fuel.
