Here's how to watch NASA astronauts Jessica Meir and Chris Williams conduct U.S. spacewalk 94
NASA astronauts Jessica Meir and Chris Williams will don their space suits and conduct a spacewalk outside the International Space Station on March 18, 2026, to prepare for the installation of two roll-out solar arrays. U.S. spacewalk 94 marks the first spacewalk outside the ISS in months, the fourth for Meir and the first for Williams. NASA will be providing the delightful facility of livestreaming this venture happening today, and here’s all you need to know to watch it live.
Everything you need to know about the U.S. Spacewalk 94 livestream
A spacewalk, also known as an extravehicular activity (EVA) in technical parlance, denotes any activity where the astronauts expose themselves in specialized suits to the weightless void of outer space, occurring outside of a space station or spacecraft. The Spacewalk 94 will commence at 8 a.m. EST; however, the comprehensive live coverage will begin at 6:30 a.m EST, as per NASA. We will see Meir and Williams exit from the orbiting laboratory’s Quest airlock to prepare the 2A power channel for future installation of the International Space Station Roll-Out Solar Arrays (IROSA), for about six and a half hours. The two astronauts are among the seven people currently working aboard the ISS as part of Expedition 74.
The coverage of this event will be available across multiple platforms like NASA+, Amazon Prime, the agency’s YouTube channel, and its X account. You can tune in accordingly, depending on your timezone, to watch the phenomenal astronauts undertake the strenuous journey outside of the ISS on any feasible streaming platform. You can also refer to NASA’s ‘Ways to Watch’ website, which offers a variety of information regarding their online streaming platforms, providing access to all the agency’s relevant programs and facilitating a comfortable viewing experience.
Experts from NASA, including Bill Spetch, operations integration manager for the International Space Station Program, alongside Diana Trujillo and Ronak Dave, spacewalk flight directors from the Flight Operations Directorate, have also previewed the upcoming spacewalk. This preview took place during a news conference at 2:00 p.m. EST on March 16 at the agency’s Johnson Space Center in Houston. You can also watch the live coverage of the news conference on the agency’s YouTube channel.
Spacewalk 94 and 95
The anticipated spacewalk 94, along with spacewalk 95, has been pending for quite some time. Originally slated for January 8, 2026, NASA astronauts Mike Fincke and Zena Cardman were expected to conduct the spacewalk on the day, but the space agency cancelled the venture due to a medical emergency with Fincke. Shortly after, an unprecedented medical evacuation of NASA's Space Crew-11 mission took place, cutting the mission short and postponing the spacewalk. The last spacewalk took place in May 2025, involving two female astronauts, Anne McClain and Nichole Ayers, as they exited the orbital outpost and completed a remarkably rare all-women spacewalk.
The upcoming spacewalks mark the 278th and 279th of their kind in the history of the International Space Station, while serving as the first for Expedition 74. The U.S. spacewalk 95 will also take place soon and will involve two NASA astronauts preparing the station’s 3B power channel for another IROSA installation. The agency will reveal the details regarding its date, time, crew involved and livestreaming information closer to the operation.
As the timer is ticking closer to the commencement of the daring spacewalk 94, get ready to watch the astronauts in their full glory, working in zero gravity in real time.
