Astronauts C.J. Sturckow (seated, left) and Pat Forrester (seated, right) sign autographs during their Oct. 7 visit to Stennis Space Center. The astronauts visited the rocket engine testing facility to thank Stennis employees for contributions to their recent STS-128 space shuttle mission. All three of the main engines used on the mission were tested at Stennis. Sturckow served as commander for the STS-128 flight; Forrester was a mission specialist. During a 14-day mission aboard space shuttle discovery, the STS-128 crew delivered equipment and supplies to the International Space Station, including science and storage racks, a freezer to store research samples, a new sleeping compartment and an exercise treadmill. The mission featured three spacewalks to replace experiments and install new equipment at the space station.
