Question

which of the following successfully launched into space, completed a mission, and landed safely back onto the surface of earth?
falcon 9
curiosity
asds
trappist-1

Explanation:

• Falcon 9 is a reusable rocket that can launch into space, complete a mission, and land back on Earth (e.g., for satellite deployment and return).
• Curiosity is a Mars rover, so it landed on Mars, not Earth.
• ASDS (Autonomous Spaceport Drone Ship) is a platform for Falcon 9 to land at sea, not a vehicle that launches/lands on its own.
• Trappist - 1 is a star system, not a vehicle.

Answer:

A. Falcon 9
