• 5 minutes

• 7 minutes

• 10 minutes

• 12 minutes

What is the primary purpose of the parachute during the rover's landing?

• To slow down the rover's descent.

• To provide additional thrust during takeoff.

• To stabilize the rover during flight.

• To collect data about the atmosphere.

What happens to the rover after it lands on Mars?

• It begins its mission to explore the Martian surface and conduct scientific experiments.

• It immediately sends a signal back to Earth and shuts down.

• It starts to build a habitat for future astronauts.

• It collects samples and returns them to Earth right away.

What does the acronym EDL stand for in the context of Mars rover landing?

• Entry Descent Landing

• Emergency Deployment Launch

• Earth Defense Line

• Extraterrestrial Delivery Logistics

What technology is used to ensure the rover lands safely on the Martian surface?

• A combination of parachutes, retro rockets, and landing gear.

• A single large parachute and airbags.

• Magnetic levitation and hovercraft technology.

• A series of controlled explosions to slow descent.

What is the speed of the rover before it lands on Mars?

• 10,000 miles per hour

• 12,000 miles per hour

• 13,000 miles per hour

What materials are used to protect the rover from heat during atmospheric entry?

• Heat shields made of ablative materials.

• Ceramic tiles for insulation.

• Metallic plates for structural support.

• Liquid cooling systems.

How does the rover communicate its status during the landing process?

• Through telemetry signals sent back to Earth.

• By using radio waves to transmit data to satellites.

• Through visual signals sent to nearby spacecraft.

• By sending smoke signals to ground control.

What are the stages of the Entry Descent Landing (EDL) process?

• Launch, Orbit, Re-entry

• Entry, Descent, and Landing
