HOUSTON (NASA PR) — Astronauts Akihiko Hoshide of the Japan Aerospace Exploration Agency (JAXA) and Thomas Pesquet of ESA (European Space Agency) will venture outside the International Space Station for a spacewalk Sunday, Sept. 12.

NASA will provide details about the procedures scheduled for the upcoming spacewalk during a news conference at 2 p.m. EDT Friday, Sept. 10, from NASA’s Johnson Space Center in Houston. Live coverage of the news conference and the spacewalk will air on NASA Television, the agency’s website, and the NASA app.

This will be the first spacewalk, or extravehicular activity (EVA) conducted by two international partner astronauts out of the space station’s Quest airlock. U.S. EVA 77, originally scheduled to take place Tuesday, Aug. 24, will focus on attaching a support bracket in preparation for future installation of the orbiting laboratory’s third new solar array. NASA astronaut Mark Vande Hei is recovering from a minor medical issue and will provide support for Pesquet and Hoshide from inside the space station.
