The Space Shuttle Program concluded this morning with the safe landing of Atlantis in Florida. The occasion was observed in various ways. At Goddard Space Flight Center in Maryland, a group picture was taken to include all those who had any involvement in the Space Shuttle Program during their careers. (I've been involved with Shuttle payload missions during much of my career.)
While it is a day for emotion and nostalgia, it is not a time for despair but a time for renewed determination to bring to reality the potential for more engagement of the commercial space sector while gaining more definition and commitment for NASAs role in leading human exploration beyond Earth orbit.
