Mars Landing

What does "Delta V" represent in the context of space travel?

• Change in distance

• Change in velocity

• Change in acceleration

• Change in direction

Approximately how much Delta V is required to reach a typical low Earth orbit from the Earth's surface?

• 1 km/s

• 6-7 km/s

• 9.4 km/s

• 24 km/s

What is the approximate total change in velocity (Delta V) required for a Starship to completely escape Earth's gravitational influence?

• 2.44 km/s

• 3.14 km/s

• 3.23 km/s

• 3.60 km/s

Why is atmospheric braking a crucial strategy for a Starship attempting to land on Mars?

• It allows the ship to gain additional speed for a quicker landing.

• It helps conserve engine fuel by using the planet's atmosphere to slow down.

• It provides a stable orbit around Mars without needing any engine burns.

• It is the only way to navigate through Mars' thick atmosphere.

How does the terminal velocity on Mars compare to that on Earth?

• It is approximately the same as on Earth.

• It is about half as fast as on Earth.

• It is around five times faster than on Earth.

• It is significantly slower due to Mars' thinner atmosphere.
