The second event of Public Lecture Series took place in one of lecture theatres of the Technical University of Milan in form of a public debate on “Asteroids and Space Debris: Challenges and Opportunities“. The event was organised and facilitated by a group of project Marie Skłodowska-Curie Early Stage Researchers: Matteo Manzi, Sai Abhishek Peddakotla, Shubham Vyas, Edoardo Legnaro, Pelayo Penarroya and Mattia Pugliatti. They introduced the Stardust-R project explaining its scope and objectives. To initiate discussion they gave short engaging talks tailored for general public. Following the initial discussions around topics of Space Debris & Space traffic management, asteroid exploration and exploitation there was an interesting informal Q&A session that lasted another 40 minutes. The event was attended mainly by staff and students of the university. An estimated number of people in the room was about 60.
