Which of the following was NOT used in Perseverance's landing process?

• Thrusters

• Jet pack

• Parachute

• Sky crane

What primarily caused the deceleration of the rover during its descent?

• The parachute

• The rover's engines

• The Martian atmosphere

• The sky crane

What is the purpose of the MEDLI2 sensors on the heat shield?
