When a spacecraft returns to earth through the atmosphere, friction with the atmosphere causes a sharp rise in temperature  In order to overcome the thermal barrier and return to Earth safely, a foreign research institute has made a new attempt on recovering the micro-satellite EGG  During the descent, EGG opened its hemispherical heat-insulating decelerating parachute, which was expanded by carbon dioxide gas
The surface material of spacecraft must have the capability of withstanding the ultra-high temperature
 Then the atmospheric resistance increased significantly and it began to enter the atmosphere slowly and fall smoothly
