NASA | Targeting Mars

The video explains the complexities of sending a spacecraft to Mars, focusing on NASA's MAVEN mission. It outlines the need to wait for optimal planetary alignment, the launch process, and the journey to Mars. Upon arrival, MAVEN must perform a precise engine burn to enter Mars' orbit. The mission aims to study Mars' atmospheric changes, providing insights into its transition from a warm, wet planet to its current cold, dry state.

Why can't a spacecraft be aimed directly at Mars?

• Mars is too small to target directly.

• Mars moves slower than Earth around the sun.

• Mars is too far away.

• Mars' atmosphere is too thick.

What is the name of the mission that launched to Mars in 2013?

What is the purpose of MAVEN's engine burn upon arrival at Mars?

• To change its direction towards the sun

• To slow down and allow Mars' gravity to capture it

• To increase its speed to match Mars

• To deploy its landing gear

How long will MAVEN's initial orbit around Mars take?

• 12 hours

• 48 hours

• 24 hours

• 35 hours

What is the main scientific goal of the MAVEN mission?

• To find water on Mars

• To search for life on Mars
