Abstract

As the first long-term on-orbit spacelab of China, TianGong-1 will stay aloft for 2 years. Its failure risk subjected to Meteoroid and Orbital Debris(M/OD) is hundreds of times higher than the risk of Shenzhou-5, Shenzhou-6 or Shenzhou-7, so the special M/OD protection designs have been applied. In order to reduce the penetration risk of radiator tube, the design of radiator has been modified by placing the tube at the side of radiator plate, and the new design does not affect the thermal control system without adding the mass. Secondly, Whipple structure is adopted in the two sides and front of spacecraft against M/OD impact.
