1. What is the primary scientific objective?Investigate planetary geology, atmospheric composition, magnetospheres, and the potential for life
2. What is the launch vehicle examples?Atlas V, Delta IV, Falcon Heavy, Ariane 5
3. What are space probes and why do we use them?Space probes are robots that travel to planets and stars. They collect pictures and data that we can't get from Earth. This helps scientists learn about our solar system.
4. How do space probes travel so far?They start their journey with powerful rockets like the Falcon Heavy or Ariane 5. Once in space, they use gravity from planets to change speed and direction, saving fuel. Ground stations and on-board computers guide them safely.
