Christina Koch posted a video showing balance difficulties during a blindfolded recovery test after the Artemis 2 Moon mission, joking that she’d have to wait to go surfing. Microgravity forces the brain to recalibrate motion signals, producing balance and proprioception issues similar to concussion or vertigo, which physical therapy helps treat. Koch spent 10 days in space (April 1–10); researchers are monitoring her and her crewmates as they readapt, while emphasizing exercise, nutrition, and mental‑health support. Koch said simple home comforts—like coffee on the porch—felt especially meaningful after the flight.
“Guess I’ll Be Waiting to Surf”: Christina Koch Details Post‑Moon Recovery After Blindfold Wobble Test

A week after returning from the Artemis 2 lunar mission, NASA astronaut Christina Koch posted a candid recovery clip showing her struggling to walk a straight line while blindfolded. In the video she wobbles and nearly falls, prompting attendants to step in; Koch lightened the moment on Instagram with, “Guess I’ll be waiting a minute to surf again.”
Why this happens: In microgravity, the brain adapts by downweighting or ignoring some of the body’s automatic motion signals. That retraining helps astronauts move and operate in space but can leave them dizzy, off balance, and disoriented on return to Earth—symptoms similar to concussion or vestibular disorders such as vertigo. Rehabilitation and physical therapy are therefore key parts of post-flight care.
What scientists know: NASA and international partners draw on decades of experience studying long-duration missions. The International Space Station (ISS) program has over 25 years of research, and Russia’s space station work stretches back to the 1970s. Those studies—published in thousands of papers—inform today’s recovery protocols and countermeasures.
Koch spent 10 days in space on Artemis 2, launching April 1 and splashing down April 10. That’s far shorter than the near-year she spent on the ISS during an earlier flight and much less than the typical six-month ISS expedition, yet even brief exposures to weightlessness can disrupt multiple systems: the sense of up and down, proprioception (awareness of limb position), and, over longer missions, bone density, muscle mass, and some gene-expression markers.
Countermeasures on Artemis 2: The Artemis 2 crew used scaled versions of station countermeasures: a balanced diet, targeted supplements, and a compact flywheel‑based resistance and cardio device for exercise. They also had access to remote medical support. Those measures aim to limit bone and muscle loss and to ease re-adaptation after return.
The crew and their milestone roles: The Artemis 2 team—Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Canadian Space Agency Mission Specialist Jeremy Hansen—made historic firsts on this flight. Koch, Glover and Hansen were, respectively, the first woman, the first person of color, and the first non‑American to travel beyond low Earth orbit on this mission.
Mental health and public attention: Psychological strain is an important part of spaceflight risk: long separations from family, confined living quarters, a high operational tempo, and the inherent dangers of the environment all increase stress. Artemis 2 crews also faced heightened scrutiny as the first humans to travel near the Moon in almost 54 years and because they agreed to unusually extensive livestreaming of daily activities.
“A simple and universally small thing. But it is also everything,”
After returning home, Koch shared her appreciation for ordinary comforts—like sharing a cup of coffee on a porch with a friend—underscoring how small, familiar moments can feel profoundly meaningful after spaceflight.
Bottom line: Koch’s blindfold wobble is a vivid, human glimpse into how microgravity alters balance and perception. Rehabilitation, exercise countermeasures, and psychological support help returning astronauts readapt, and the wealth of ISS-era research continues to guide those efforts.
