Europe's Hera spacecraft heads to investigate damaged Didymos asteroid

The Hera spacecraft was launched from Cape Canaveral in Florida as part of an international mission to study asteroid deflection. The mission aims to determine the effectiveness of a previous experiment, where NASA's Dart spacecraft intentionally collided with a small asteroid called Dimorphos. The Hera spacecraft will travel to the asteroid over the next two years to examine the impact's aftermath and gather data on the asteroid's changes in shape, size, and velocity. This test is seen as a crucial step in developing a planetary defense system that could potentially save the Earth from future asteroid threats.
We don't really know very well the environment in which we are going to operate.
But that's the whole point of the mission is to go there and find out.
It's not to avoid an extinction of the human race. It's to create a system to minimize the damage as much as we can. The dinosaurs didn't have a space program, but we do.
We need to understand what are the physical properties of these asteroids? What are they made of? Are they blocks of rock? Are they made of sand inside?
The more detail we can glean the better as it may be important for planning a future deflection mission should one be needed.
