ISS045e152270 (12/01/2015) --- NASA astronaut Kjell Lindgren takes images of the Earth on board the International Space Station on Dec. 1, 2015 from the Cupola, the 360 degree viewing and robotic Canadarm 2 control area. Later this area will be used by Lindgren and NASA astronaut Scott Kelly to use the station’s Canadarm 2 robotic arm to reach out and grapple the Orbital ATK CRS-4 "Cygnus" spaceship full of equipment and supplies.

NASA astronaut Terry Virts of Expedition 43 on the International Space Station checks the remote control Canadarm2 on Apr.26, 2015. The Canadarm 2 is used to grapple arriving spacecraft and moving them to their docking ports.

S100-E-5018 (20 April 2001) --- One of the crew members of STS-100 aimed a digital still camera through Endeavour's aft flight deck windows to record this image of the cargo bay, backdropped against a scene of black space and Earth's horizon. Housed in the bay, beyond the docking mechanism in the foreground, is the Italian Space Agency-provided Raffaello cargo module, which is carrying several tons of equipment for the Expedition Two crew and racks of hardware for installation in Destiny which will be used for scientific research in the future. Raffaello, which is the second of three such logistics modules, will be berthed to the ISS on April 23 so its contents can be transferred to the station throughout the course of docked operations. Also in the bay is the 57-foot-long Canadarm2, which will be mounted on the Destiny Laboratory for future station assembly work. Endeavour's Canadian-built Remote Manipulator System (RMS) arm can be seen in its berthed position on the port side of the payload bay.

ISS043E122264 (04/17/2015) --- The Canadarm 2 reaches out to grapple the SpaceX Dragon cargo spacecraft and prepare it to be pulled into its port on the International Space Station. Robotics officers at Mission Control, in the Johnson Space Center Houston Texas will command the Canadarm2 robotic arm to maneuver Dragon to its installation position at the Earth-facing port of the Harmony module where it will reside for the next five weeks.

A Canadian "handshake" in space occurred on April 28, 2001, as the Canadian-built space station robotic arm (Canadarm-2) transferred its launch cradle over to Endeavor's robotic arm. Marning the controls from the shuttle's aft flight deck, Canadian Mission Specialist Chris A. Hadfield of the Canadian Space Agency (CSA) was instrumental in the activity. The Spacelab pallet that carried the Canadarm2 robotic arm to the station was developed at the Marshall Space Flight Center (MSFC) in Huntsville, Alabama.

A convoy of specialized support vehicles follow the Space Shuttle Endeavour as it is towed up a taxiway at NASA's Dryden Flight Research Center on Edwards Air Force Base, California, after landing on May 1, 2001. The two largest vehicles trailing the shuttle provide electrical power and air conditioning to the shuttle's systems during post-flight recovery operations. The Endeavour had just completed mission STS-100, an almost 12-day mission to install the Canadarm 2 robotic arm and deliver some three tons of supplies and experiments to the International Space Station. The landing was the 48th shuttle landing at Edwards since shuttle flights began in 1981. After post-flight processing, the Endeavour was mounted atop one of NASA's modified Boeing 747 shuttle carrier aircraft and ferried back to the Kennedy Space Center in Florida on May 8, 2001.

Also on board will be the Expedition Five crew who will replace Expedition Four on the Station. Launch has been rescheduled for Monday, June 3, between 4 and 8 p.m. EDT

KENNEDY SPACE CENTER, FLA. -- Expedition 5 Commander Valeri Korzun (RSA), left, talks with astronaut Tracy Caldwell during suitup for the scheduled liftoff of Space Shuttle Endeavour at 7:44 p.m. EDT. This is Korzun's 2nd Shuttle flight. 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. The MBS will be installed on the Mobile Transporter to complete the Canadian Mobile Servicing System, or MSS.

KENNEDY SPACE CENTER, FLA. -- STS-111 Mission Specialist Franklin Chang-Diaz suits up for launch, scheduled at 7:44 p.m. EDT, May 30, 2002. This is his seventh Shuttle flight, only the second astronaut to achieve that number. 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

KENNEDY SPACE CENTER, FLA. -- Before leaving KSC, the STS-111 crew and Expedition 5 crew stop to talk to media at the Shuttle Landing Facility. At the microphone is Commander Kenneth Cockrell. Behind him, left to right, are Pilot Paul Lockhart; Expedition 5's Commander Valeri Korzun, astronaut Peggy Whitson and cosmonaut Sergei Treschev; Mission Specialists Philippe Perrin and Franklin Chang-Diaz. Perrin is with the French Space Agency; Korzun and Treschev are with the Russian Space Agency. The crews have been taking part in Terminal Countdown Demonstration Test activities that include emergency egress training and a simulated launch countdown. Expedition 5 will travel to the International Space Station on mission STS-111 as the replacement crew for Expedition 4, who will return to Earth aboard the orbiter. Mission STS-111 is known as Utilization Flight 2, carrying supplies and equipment in the Multi-Purpose Logistics Module Leonardo to the International Space Station. The payload also includes the Mobile Base System, which will be installed on the Mobile Transporter to complete the Canadian Mobile Servicing System, or MSS, and a replacement wrist_roll joint for Canadarm 2. 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. Launch is scheduled for May 30, 2002
