Summary of his talk: "Anything that goes up will eventually come down… In the case of launchers and satellites in Low Earth Orbit, this means returning to Earth through an atmospheric reentry at very high velocity. This generates high heat fluxes, partially ‘melting’ the objects. Typically, about 20% survive reentry and pose a risk to people on the ground; however, the remaining 80% will stay in the upper atmosphere for some time, leading to unwanted disruptions to the ozone layer and contributing to greenhouse gas effects. How can we solve this dilemma—putting people at risk or damaging the atmosphere?"
