[Music] I have just one aim uh for my talk today and that is to show you why we should start caring more about stuff like this and also the blades they come from. This is actually a piece of a meteorite. I got it as a gift from some dear friends and colleagues when I got my PhD.So obviously it's highly precious to me. It has all kinds of personal and sentimental value to it. You don't probably have much reasons to care about this particular rock.And uh if my friends would have given me just any ordinary roc ...

Space Debris Problem - A marble in orbit gains 8 kilometers per second of speed, about 20 times faster than a bullet, posing a significant threat to satellites [1] - A tiny object in orbit possesses the energy of a hand grenade, capable of shattering satellites into thousands of dangerous fragments [2][3] - There are over 36,000 large pieces of debris being tracked and millions more too small to track, constantly circling Earth [6] - Space is becoming overcrowded, increasing the risk of collisions, similar to a busy highway [8] - The 2009 collision between an American and a Russian satellite created over 2,000 new pieces of debris, many still posing a risk after 15 years [9][10] - The Kessler syndrome describes a potential runaway chain reaction of collisions, a very real possibility if no action is taken [12][13][14] - A serious collision in space could disrupt essential satellite-dependent systems like navigation, communication, weather updates, and financial transactions, potentially causing a global blackout [5][15][16] Clear Space Solution - Clear Space is launching its first mission in 2028 to remove space debris using a spacecraft with an innovative grasping system [17][18] - Clear Space One will capture debris and release it back into Earth's atmosphere to burn up without leaving residue [21] - The goal is to make space debris cleanup a routine part of satellite launches and disposal [21][22] Call to Action - Addressing space debris is a shared responsibility requiring collaboration between governments, private companies, scientists, and the public [24]

This is a marble. It's small. It's light. It's only a few grams.It's quite harmless in my hand. But if we were to place this marble in orbit, it would suddenly gain 8 kilometers per second of speed. That's 8 kilometers per second.Think about it. That's around 20 times faster than a bullet. It will take this marble less than 10 minutes to travel from London to New York.And even something this tiny and innocent could cause a disaster. Why. Well, at those speeds, it's not only about the size. It's also about t ...
