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 technology will the Hera spacecraft use to examine the asteroid structure?

What will the Hera spacecraft collect from the crater formed by the DART experiment?
