  \frametitle{Some comparisons of orbital energy}

  \begin{itemize}
    \item Taking 1 kg to orbit requires about 32.4 megajoules of energy.
    \item That's the same as:
      \begin{itemize}
        \item The energy in a freight train going 34 MPH.
        \item The energy in 155 pounds of TNT.
       \end{itemize}

  \frametitle{Recap: what you need to get to orbit}

  \begin{itemize}
    \item Big (!) rocket to get into space and acheive orbital velocity.
    \item Oh, right: and lawyers. Lots and lots of lawyers.
    \item Some way to \textbf{steer} the rocket to get it into an orbit.
  \end{itemize}
