To the crew of STS-119, welcome back to Earth and congrats on a safe and successful mission. While there were several mission objective, the most highlighted of the trip was the installation of the last set of solar arrays on the ISS. It takes true endurance to make the round trip to the ISS and back and those that do it are amazing people. American society has seemingly gotten away from paying tribute to the astronauts that make these trips, but I believe that they deserve hero status.
