On this day in 2011 the Space Shuttle Atlantis landed at Kennedy Space Center. Its mission, STS-135, was the last of the 30-year-old program of shuttle flights. Atlantis’s four-person crew delivered two modules of equipment and supplies to the International Space Station. Also onboard was a miniaturized satellite known as PSSC-2, or Picosatellite Solar Cell Testbed 2. On the 13th day of the mission, PSSC-2 became the 180th and last Space Shuttle payload to be placed into orbit.
