On the night of Aug. 5,1 was privileged to watch as the Jet Propulsion Laboratory (JPL) team brought NASA's Curiosity rover to a perfect landing on Mars. From launch on an Atlas 5 to gentle touchdown, this program has inspired and captured the imagination of the American people. And I saw hundreds of brilliant JPLers sharing tears of joy, hugs and exultant smiles. Curiosity's landing was a wonderful moment. I've been in the space business for over 40 years. For our community, launch and touchdown provide the biggest challenges and the most exhilarating, heart-pumping excitement.
