Detailed explanation-1: -When human spaceflight began, NASA used the gravity assist concept so that spacecraft could conserve fuel. Which statement explains why the gravity assist concept was useful for spacecraft to successfully travel and return to Earth? It gave spacecraft a timed trajectory.
Detailed explanation-2: -Gravity is an important tool in space flight, especially in the form of planning flight paths for missions. Using a concept called gravity assist, the trajectory and speed of a spacecraft can be changed by encountering large bodies, such as planets, in space.
Detailed explanation-3: -Two main types of tiles are used: Low-temperature Reusable Surface Insulation (LRSI) and High-temperature Reusable Surface Insulation (HRSI). LRSI tiles protect the orbiter from temperatures of 700 and 1, 200 degrees Fahrenheit, and are mostly situated on the top of the spacecraft.
