A spacecraft experiences damage to its heat shield upon re-entry to Earth's atmosphere. Which of the following is the most likely cause of this damage?

• The spacecraft re-entered Earth's atmosphere too steeply

• The spacecraft's angle of re-entry was too shallow.

• The spacecraft's heat shield was damaged during launch

• The spacecraft re-entered Earth's atmosphere during a solar storm

What is the purpose of a rocket during launch of a spacecraft?

• to provide enough power to overcome Earth's gravity

• to give extra thrust to help steer the spacecraft into orbit

• to balance the spacecraft as it moves out of Earth's atmosphere

• to prevent the spacecraft from moving faster than orbital velocity
