NASA & ESA to conduct planetary defense tests on asteroid

The video discusses the Hera mission, which aims to gather data from Diddymoon, a moonlet of the binary asteroid system Didimos. This follows NASA's DART mission, which plans to crash a spacecraft into Diddymoon to alter its trajectory. The binary system is located 11 million kilometers from Earth. Diddymoon is about 160 meters wide, similar to the Great Pyramid of Giza. Hera will study the impact crater in 2026, collecting samples and using thermal imaging to analyze the asteroid's structure.

What is the primary goal of the Hera mission?

• To land on the Moon

• To study the Sun

• To explore Mars

• To gather data from Diddymoon

What is the purpose of NASA's DART mission?

• To redirect an asteroid's path

• To explore the rings of Saturn

• To collect samples from Mars

• To study the atmosphere of Venus

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

• 12 kilometers per second

• 9 kilometers per second

• 6 kilometers per second

• 3 kilometers per second

What is the approximate width of Diddymoon?

• 100 meters

• 160 meters

• 200 meters

• 250 meters

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

• Ultrasound

• Laser scanning

• Thermal imaging

• Radar mapping
