How does the amount of a rocket's thrust affect its trajectory? What does it take for an orbiting spacecraft to escape its orbit? If you were to plan a mission to Mars, what are the key phases that you need to include in your mission?

Thrust helps to move the rocket against gravity.

Explanation:

The amount of a rocket's thrust affect its trajectory because this thrust help the rocket to move against the gravity of the earth. More force in the form of thrust is needed by orbiting spacecraft to escape its orbit because the orbit does not allow the orbiting spacecraft to escape so for that force is needed to to against its orbit. First, we need to escape from the gravity of earth then go towards the mars. after entering the gravity of mass, we used a force which helps in safe landing on the mars.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
