Original Note:
The minus sign in front of p_0 means that as p_0 gets smaller, Thrust goes up. This tells us that an atmosphere outside the rocket is not necessary to "push against", and in fact decreases thrust. All else being equal maximum thrust is when p_0 = 0, as in outer space. https://www.grc.nasa.gov/www/k-12/airplane/rockth.html
