The STS-111 mission, the 14th Shuttle mission to visit the International Space Station (ISS), was launched on June 5, 2002 aboard the Space Shuttle Orbiter Endeavour. On board were the STS-111 and Expedition Five crew members. Astronauts Kerneth D. Cockrell, commander; Paul S. Lockhart, pilot; and mission specialists Franklin R. Chang-Diaz and Philippe Perrin were the STS-111 crew members. Expedition Five crew members included Cosmonaut Valeri G. Korzun, commander; Astronaut Peggy A. Whitson and Cosmonaut Sergei Y. Treschev, flight engineers. Three space walks enabled the STS-111 crew to accomplish the delivery and installation of the Mobile Remote Servicer Base System (MBS), an important part of the Station's Mobile Servicing System that allows the robotic arm to travel the length of the Station, which is necessary for future construction tasks. In this photograph, Astronaut Philippe Perrin, representing CNES, the French Space Agency, participates in the second scheduled EVA. During the space walk, Perrin and Chang-Diaz attached power, data, and video cables from the ISS to the MBS, and used a power wrench to complete the attachment of the MBS onto the Mobile Transporter (MT).

In this photograph, Astronaut Franklin R. Chang-Diaz participates in the first scheduled session of extra vehicular activity (EVA) for the STS-111 mission. During the space walk, Chang-Diaz and Perrin attached a Power and Data Grapple Fixture onto the ISS's P6 Truss, setting the stage for the future relocation of the P6. The next major task was to remove Service Module Debris Panels from Space Shuttle Endeavour's payload bay and attach them to their temporary location on Pressurized Mating Adapter 1 (PMA-1). The space walkers also removed thermal blankets to prepare the MBS for installation onto the station's Mobile Transporter (MT).

Mission STS-111 is the 18th flight of Endeavour and the 110th flight overall in NASA's Space Shuttle program. On mission STS-111, astronauts will deliver the Leonardo Multi-Purpose Logistics Module, the Mobile Base System (MBS), and the Expedition Five crew to the Space Station. During the seven days Endeavour will be docked to the Station, three spacewalks will be performed dedicated to installing MBS and the replacement wrist-roll joint on the Station's Canadarm2 robotic arm. Liftoff is scheduled for 5:22 p.m. EDT from Launch Pad 39A

KENNEDY SPACE CENTER, FLA. - Wearing a cap with the New York Fire Department logo, Expedition 5 Commander Valeri Korzun suits up for the second launch attempt aboard Space Shuttle Endeavour on mission STS-111 to the International Space Station. This is Korzun's first Shuttle flight. Expedition 5 will replace Expedition 4 on board the Station. Expedition 4 crew members will return to Earth with the STS-111 crew on Endeavour.

KENNEDY SPACE CENTER, FLA. - After rollback of the Rotating Service Structure, Space Shuttle Endeavour is bathed in light. Seen above the orange external tank behind Endeavour is the "beanie cap," or vent hood assembly at the end of the gaseous oxygen vent arm. The orbiter access arm extends to the cockpit area of Endeavour. At the end of the arm is the White Room, , an environmental chamber that provides crew access into the orbiter. STS-111 is the second Utilization Flight to the International Space Station, carrying the Multi-Purpose Logistics Module Leonardo, the Mobile Base System (MBS), and a replacement wrist/roll joint for the Canadarm 2. Also onboard Space Shuttle Endeavour is the Expedition 5 crew who will replace Expedition 4 on board the Station. The MBS will be installed on the Mobile Transporter to complete the Canadian Mobile Servicing System, or MSS. The mechanical arm will then have the capability to "inchworm" from the U.S. Lab Destiny to the MSS and travel along the truss to work sites. Expedition 4 crew members will return to Earth with the STS-111 crew on Endeavour. Launch is scheduled at 7:44 p.m. EDT, May 30, 2002

KENNEDY SPACE CENTER, FLA. -- In the Space Station Processing Facility, overhead cranes lower the Mobile Base System onto the weight and center of gravity stand. Part of the payload on mission STS-111 to the International Space Station, the MBS will be installed on the Mobile Transporter to complete the Canadian Mobile Servicing System, or MSS. The mechanical arm will then have the capability to "inchworm" from the U.S. Lab Destiny to the MSS and travel along the truss to work sites. STS-111 is the second utilization flight (UF-2) to the Space Station and will also carry the Expedition 5 crew to replace Expedition 4. Launch is scheduled for May 31, 2002

KENNEDY SPACE CENTER, FLA. -- In the Space Station Processing Facility, workers watch while overhead cranes move the Mobile Base System to the weight and center of gravity stand.

Launched aboard the Space Shuttle Endeavor on June 6, 2002, these four astronauts comprised the prime crew for NASA's STS-111 mission. Astronaut Kenneth D. Cockrell (front right) was mission commander, and astronaut Paul S. Lockhart (front left) was pilot. Astronauts Philippe Perrin (rear left), representing the French Space Agency, and Franklin R. Chang-Diaz were mission specialists assigned to extravehicular activity (EVA) work on the International Space Station (ISS). In addition to the delivery and installation of the Mobile Base System (MBS), this crew dropped off the Expedition Five crew members at the orbital outpost, and brought back the Expedition Four trio at mission's end.

KENNEDY SPACE CENTER, FLA. -- In the IMAX-2 Theater at the Visitor Complex, NASA Administrator Sean O'Keefe conducts the Administrator's Briefing for specially invited guests attending the launch of mission STS-111. The briefing is a regularly scheduled event in KSC's prelaunch activities. STS-111 is the second Utilization Flight to the International Space Station, carrying the Multi-Purpose Logistics Module Leonardo, the Mobile Base System (MBS), and a replacement wrist/roll joint for the Canadarm 2. Also on board will be the Expedition Five crew who will replace Expedition Four on the Station. Launch is scheduled for May 30 at 7:44 p.m. EDT
