Launched on July 26, 2005 from the Kennedy Space Center in Florida, STS-114 was classified as Logistics Flight 1. Among the Station-related activities of the mission were the delivery of new supplies and the replacement of one of the orbital outpost's Control Moment Gyroscopes (CMGs). STS-114 also carried the Raffaello Multi-Purpose Logistics Module (MPLM) and the External Stowage Platform-2. Back dropped by popcorn-like clouds, the MPLM can be seen in the cargo bay as Discovery undergoes rendezvous and docking operations. Cosmonaut Sergei K. Kriklev, Expedition 11 Commander, and John L. Phillips, NASA Space Station officer and flight engineer photographed the spacecraft from the International Space Station (ISS).

CAPE CANAVERAL, Fla. – A crane lifts a new parabolic telemetry antenna and tracker camera to the roof of the Launch Control Center, or LCC, in Launch Complex 39 at NASA's Kennedy Space Center in Florida. This antenna and camera system is the first of three that will be installed on the LCC roof for the Radio Frequency and Telemetry Station RFTS, which will be used to monitor radio frequency communications from a launch vehicle at Launch Pad 39A or B as well as provide radio frequency relay for a launch vehicle in the Vehicle Assembly Building. The RFTS replaces the shuttle-era communications and tracking labs at Kennedy. The modern RFTS checkout station is designed to primarily support NASA's Space Launch System, or SLS, and Orion spacecraft, but can support multi-user radio frequency tests as the space center transitions to support a variety of rockets and spacecraft.

Mechanical technicians, Nicholas Kwiatkowski and Thomas Huber, guide the Ocean Color Instrument (OCI) as it is suspended on a crane to install an adapter plate and for additional integration operations. OCI is a highly advanced optical spectrometer that will be used to measure properties of light over portions of the electromagnetic spectrum. It will enable continuous measurement of light at finer wavelength resolution than previous NASA satellite sensors, extending key system ocean color data records for climate studies. OCI is PACE's (Plankton, Aerosol, Cloud, ocean Ecosystem) primary sensor built at Goddard Space Flight Center in Greenbelt, MD.
