          • $$\Delta v$$ is the maximum change of velocity
          • $$m_o$$ is the initial mass, with propellant (wet mass)
          • $$m_f$$ is the final mass, without propellant (dry mass)
          • $$v_e$$ is the effective exhaust velocity
        • Named after Russian scientist Konstantin Tsiolkovsky
      • It takes us just as long to build a factory compared to getting to full production level
