Watch live: first #SpacewalkForAMS

In a special live transmission between ESA’s astronaut centre in Cologne, Germany, and the European laboratory for particle physics CERN in Switzerland, experts will provide commentary and insight throughout what is being described as the most complex series of spacewalks since the repair of the Hubble Space Telescope. Coverage of the entire spacewalk, including the opening two hours of expert commentary, will be streamed live on esawebtv.esa.int

Luca and his spacewalking partner NASA astronaut Andrew Morgan will exit the Space Station airlock at around 13:05 CET (12:05 GMT) equipped with special tools designed to maintain the cosmic ray detector, Alpha Magnetic Spectrometer AMS-02.

It is the first of at least four spacewalks the pair will perform to upgrade AMS-02’s cooling system and extend the experiment’s life.

As the lead spacewalker, known as ‘EV1’, Luca will wear a white spacesuit with red stripes while Andrew wears a white spacesuit with no stripes.

The pair will be supported by NASA astronauts Christina Koch and Jessica Meir who will operate the Canadarm2 robotic arm from inside the Station. This will help position Luca at to the hard-to-reach work site, located on top of the Station’s S3 Truss structure between a pair of solar arrays and radiators.

Speakers

Speakers at the European astronaut centre include ESA ISS Operations and Astronaut Group leader Frank de Winne, Head of ESA EVA Training Unit Hervé Stevenin, ESA Eurocom Team Coordinator Andrea Boyd and Stefan Schael, German AMS-02 Project lead and astrophysicist from RWTH Aachen University.

These speakers will be supported by scientists at CERN and a special pre-recorded interview with particle physicist and Nobel Prize winner Samuel Ting.

Viewers are encouraged to tweet their spacewalk questions to @esaspaceflight or @cern using the hashtag #SpacewalkForAMS. The live event will also be streamed via ESA’s Facebook page and CERN’s social channels.
