(under the class definition) Subject matter s comprising a machine or structure especially designed for travel in the upper reaches of and/or beyond the atmosphere of a celestial body, (e.g., earth).
(1) Note. By upper reaches of earth's atmosphere is meant the height at or beyond which the atmosphere is incapable of providing (1) lift or sustention to a winged or other aircraft or (2) sufficient oxygen for operating the propulsion system of an aircraft.
(2) Note. A machine or structure (manned or unmanned) which is (1) disclosed as a body which is to be placed in orbit (i.e., satellite) about a celestial body (e.g., earth) or (2) solely disclosed as a vehicle for use in outer space travel is considered proper for classification here.
(3) Note. Here are structures to control the heat on all or part of a vehicle caused by the resistance to a vehicle moving through the earth's atmosphere. A structure in the
form of a coating or layer on the whole or a part of the surface of a vehicle in itself is not proper for this subclass. A heat control device claimed merely in terms of the composition or material of which it is composed is classified in an appropriate composition or material class.
