NASA Astronauts Complete 7-Hour Spacewalk at ISS

Floating 250 miles above Earth, NASA astronauts Chris Williams and Jessica Meir spent over seven hours working outside the International Space Station on March 18, 2026. Their mission? Prepare the orbital laboratory for a major power boost.

The duo completed tasks that will allow future crews to install new roll-out solar arrays. These advanced panels will provide extra electricity to support critical systems on the aging space station.

Before venturing outside, Williams underwent a spacesuit fit check inside the Quest airlock on January 2. The verification process ensures the suit is airtight and comfortable, a crucial safety step before any spacewalk.

Floating in the vacuum of space for seven hours and two minutes requires intense physical endurance and mental focus. The astronauts worked methodically through their checklist while orbiting Earth at over 17,000 miles per hour.

Why This Inspires

This spacewalk represents more than routine maintenance. The new solar arrays will help power the station through its final years of operation and support its safe, controlled return to Earth when that time comes.

Williams and Meir's work ensures that critical research can continue aboard the ISS. Every experiment conducted there, from growing food in space to testing new medical treatments, depends on reliable power.

Their collaboration also showcases the teamwork essential for space exploration. Success in orbit requires trust, preparation, and people working together toward a common goal.

This successful spacewalk keeps humanity's most ambitious science project running strong.
