Astronaut Zena Cardman Films Spectacular Northern Lights Over U.S. — “See If You Can Spot Houston”

Zena Cardman, a 38-year-old NASA astronaut aboard the ISS, filmed vivid green, purple and red auroras over the United States on Nov. 17 and posted the footage to Instagram. Cardman — a commander on the SpaceX Crew-11 mission that launched Aug. 1 — challenged viewers to spot Houston and Florida in the same frame. Experts linked the display to one of the strongest solar storms in about 20 years, an event that can disrupt satellites and delayed a planned U.S. Mars rocket launch.

Astronaut Zena Cardman Films Spectacular Northern Lights Over U.S. — “See If You Can Spot Houston”

NASA astronaut Zena Cardman captured vivid bands of green, purple and red aurora sweeping over the United States from the International Space Station on Nov. 17. The short video, shared on her Instagram account, provides a rare orbital view of the aurora borealis.

“I’ve still never seen aurora from below, but up here, it’s a frequent show. Last week’s was especially good,” Cardman wrote. “See if you can spot Houston, Florida, and the northern lights all in one frame, before we head out across the Gulf and some great lightning storms over South America at sunrise.”

Cardman, 38, is serving as a commander on NASA’s SpaceX Crew-11 mission, which launched on Aug. 1. As the ISS passed over North America she filmed the colorful display, and followers on social media responded with awe, describing the footage as "incredible" and "epic."

What caused the display

Space weather experts said the event coincided with one of the most powerful solar storms in roughly two decades. A strong eruption on the Sun hurled charged particles toward Earth; when those particles strike the upper atmosphere they excite gases and produce the glowing curtains of the aurora.

Why it matters

Beyond its visual spectacle, a major solar storm can disrupt satellites, communication systems and other electronic infrastructure. Officials also reported that heightened solar activity contributed to a delay of a planned U.S. Mars rocket launch.

The video highlights both the beauty and practical significance of space weather and shows how the International Space Station offers a unique platform for observing these global phenomena.
