The edge of space—Where does outer space begin?
APR 13, 2022
In this webinar we will discuss how atmospheric drag causes satellites to reenter, and look at historical data on where this occurs. We will compare it to the structure and density profile of the Earth’s atmosphere and discuss where the forces of gravity become more important than atmospheric forces, and how this varies with time and place. We will also review some of the historical ideas on the subject. Originally aired April 2022.
The Editor’s Series of webinars runs throughout the year and comprises a range of popular topics hand-selected by the Physics Today editorial team based on their alignment with our audience’s diverse interests.
