The invention provides a vibration reduction and isolation zero thermal expansion aerospace craft bearing structure and an aerospace craft, and relates to the technical field of aerospace crafts. A cell element structure in the aerospace craft bearing structure comprises two sub cell element structures which are mirror images of each other, each sub cell element structure comprises N curved rods and two oppositely-arranged frame structures, each frame structure comprises N straight rods, each straight rod is provided with a first end and a second end which are opposite, and N is an even number larger than or equal to 4; in the same frame structure, the first ends of the straight rods are connected, and the second end of each straight rod is a free end; in the same sub-cell structure, the straight rods in different frame structures are in one-to-one correspondence, one end of each curved rod is connected with the second end of the straight rod in one frame structure, and the other end of each curved rod is connected with the second end of the other straight rod adjacent to the opposite straight rod in the other frame structure; the connected frame structures in the two sub-cell structures are twisted relative to the frame structures away from each other in the two sub-cell structures.
