ISS Expedition 51 is the mission name for the 51st long-term crew of the International Space Station (ISS). The mission began with the disengagement of the Soyuz MS-02 spacecraft from the ISS on April 10, 2017 and ended with the disengagement of Soyuz MS-03 on June 2, 2017.

Substitute team

Since Expedition 20, no official replacement team has been announced due to the permanent training for the six-person crew. Unofficially, the backup crews of the two Soyuz feeder spaceships MS-03 and MS-04 (see there) are considered substitute crews for Expedition 51. As a rule, these crews are deployed two missions later.

Crew exchange

On April 20, 2017 - ten days after the start of the expedition - the feeder spaceship Soyuz MS-04 docked with the ISS after a six-hour flight; the ISS crew was increased to five people.

The day before Soyuz MS-03 undocked with Oleg Novizki and Thomas Pesquet, Fyodor Yurtschichin took over the ISS command . Together with Jack Fischer and Peggy Whitson, who exceptionally stayed on board for a third expedition, he formed the initial crew of the subsequent ISS Expedition 52 .

Freight traffic

Cygnus OA-7 just before docking

On April 22, 2017, Commander Peggy Whitson and Thomas Pesquet used the Canadarm2 gripper arm and captured the Cygnus OA-7 cargo ship . Then the gripper arm was rotated by commands from the ground station so that Cygnus could be attached to the underside of the Unity module .

External works

Peggy Whitson on her first spacecraft mission

On May 12th, Peggy Whitson and Jack Fischer replaced an electronics unit on the spare parts platform EXPRESS Logistics Carrier (ELC) as part of an EVA . The replacement parts were brought to the station by Cygnus OA-7 . They also mounted a protective shield on the Pressurized Mating Adapter -3 (PMA-3), which was moved from the Tranquility module to the Harmony module in March .

On May 20, a multiplexer-demultiplexer (MDM) data relay box on the S0 grid element failed . Exactly this box was only installed on March 30, 2017 by Shane Kimbrough and Peggy Whitson with improved software during an external mission. These double redundant boxes control the functions of radiators , solar panels , cooling circuits and other station hardware. Since a failure of the other box, which is now active alone, would lead to massive restrictions in ISS operations, an unscheduled EVA was set for May 23rd. The spacecraft was carried out by Peggy Whitson and Jack Fischer. While Whitson was replacing the broken box, Fischer installed a pair of antennas for wireless communication on the Destiny laboratory module .
