The STS-100 mission launched for the International Space Station (ISS) on April 19, 2001 as the sixth station assembly flight. Main objectives included the delivery and installation of the Canadian-built Space Station Remote Manipulator System (SSRMS), or Canadarm2, the installation of a UHF anterna for space-to-space communications for U.S. based space walks, and the delivery of supplies via the Italian Multipurpose Logistics Module (MPLM) "Raffaello". This is an STS-110 onboard photo of Astronaut James S. Voss, Expedition Two flight engineer, peering into the pressurized Mating Adapter (PMA-2) prior hatch opening. The picture was taken by one of the STS-100 crew members inside the PMA.

As the Space Shuttle Discovery began its separation from the International Space Station (ISS), a crew member captured this view of the ISS, revealing new additions to the complex. Most of the Z1 truss structure is visible, along with the recently installed Pressurized Mating Adapter (PMA-3).

On Aug. 9, 2021, technicians ready the payload adapter (PMA) for mating operations in preparation for NASA’s Landsat 9 mission at Vandenberg Space Force Base in California. On one end, the PMA will attach to the second stage of a United Launch Alliance Atlas V rocket. On the other, it will attach to the evolved expendable vehicle secondary payload adapter – the piece of flight hardware that connects the spacecraft to the PMA. Landsat 9 will launch on the Atlas V from Space Launch Complex 3 at Vandenberg in September 2021. The launch is being managed by NASA’s Launch Services Program based at Kennedy Space Center, America’s multi-user spaceport. The Landsat 9 satellite will continue the nearly 50-year legacy of previous Landsat missions. It will monitor key natural and economic resources from orbit. Landsat 9 is managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland. The satellite will carry two instruments: the Operational Land Imager 2, which collects images of Earth’s landscapes in visible, near infrared and shortwave infrared light, and the Thermal Infrared Sensor 2, which measures the temperature of land surfaces. Like its predecessors, Landsat 9 is a joint mission between NASA and the U.S. Geological Survey.

KENNEDY SPACE CENTER, FLA. - Workers in the Orbiter Processing Facility bay 1 watch the progress of the Pressurized Mating Adapter-3 (PMA-3) as it is transferred to the payload bay of the orbiter Discovery. A component of the International Space Station, the PMA-3 will fly on Shuttle mission STS-92, scheduled to launch October 5. The mission will be the fifth flight to the Space Station, and the 100th Shuttle flight overall. PMA-3 provides shuttle docking port for solar array installation on flight 4A (mission STS-97 scheduled for November 30), and Lab installation on flight 5A (mission STS-98, scheduled for January 18, 2001).

International Space Station (ISS) contractors erect access scaffolding around the Pressurized Mating Adapter-1 (PMA-1) for the ISS in KSC’s Space Station Processing Facility. A PMA is a cone-shaped connector that will be attached to Node 1, the space station’s structural building block, during ground processing. The white flight cables around PMA-1 will assist in connecting the node to the U.S.-financed, Russian-built Functional Cargo Block, a component that supplies early power and propulsion systems for the station. Node 1 with two adapters attached will be the first element of the station to be launched aboard the Space Shuttle Endeavour on STS-88 in July 1998
