PROBLEM TO BE SOLVED: To provide a spacecraft body structure which is relatively simply structured but yet secures a desired rigidity for the fuselage of the spacecraft while realizing lighter weight.SOLUTION: The present invention relates to a spacecraft body structure to be transported into aerospace, comprising: a pair of cylindrical barrels 201 coupled such that their internal spaces are communicated with each other in one direction; and reinforcement members 101 jointed to interior walls of respective barrels constituting the pair of cylindrical barrels and reinforcing the barrels. The reinforcement member includes: through holes 102 which penetrate, in a thickness direction, a plate-like member constituting the reinforcement member; and rib structure parts formed in a part of the plate-like member so as to respectively surround openings of the through holes at opening peripheral edge parts of the through holes.SELECTED DRAWING: Figure 1
