NASA & ESA to conduct planetary defense tests on asteroid

The video discusses the Hara mission, which aims to gather data from Didi Moon, a moonlet of the binary asteroid system Didimos. NASA's DART mission will crash a spacecraft into Diddymoon to alter its trajectory. The Hera spacecraft will later study the impact crater, collecting samples and using thermal imaging to analyze the asteroid's structure.

What is the primary goal of the Hera mission?

• To explore Mars

• To gather data from Diddymoon

• To study the Sun

• To land on the Moon

What is the purpose of NASA's DART mission?

• To explore the rings of Saturn

• To study the atmosphere of Venus

• To redirect an asteroid's path

• To collect samples from Mars

How fast is the DART spacecraft expected to travel when it impacts Diddymoon?

• 6 kilometers per second

• 3 kilometers per second

• 9 kilometers per second

• 12 kilometers per second

What is the approximate width of Diddymoon?

• 80 meters

• 200 meters

• 120 meters

• 160 meters

What technology will Hera use to examine the asteroid's structure?

• Radar mapping

• Thermal imaging

• Laser scanning

• Ultrasound
