Another historical landmark has been reached with Challenger's last launch today. As the ship took off, even the birds scattered to avoid its power. American innovation has always been a cornerstone of our greatness. Now we are struggling with our infrastructure because we were first and much of the world has caught up and lapped us with the latest of versions of our own inventions.

Even in challenging times like these, it is my hope that we will find a way to continue our work keeping our eyes on the stars and beyond. Bon Voyage!
