Can Astronauts Wear Jewelry in Space?

Jewelry is often worn as a symbol of love, expression and identity. But can astronauts bring this touch of humanity into the cold, zero-gravity environment of space? The answer is yes, though it’s not as common or straightforward as wearing jewelry on Earth. As a jewelry lover, it's fascinating to think about astronauts wearing jewelry in space and how these personal items make their way beyond our atmosphere.

Space presents unique challenges that make wearing jewelry complicated. In microgravity, items that dangle can float unpredictably and potentially interfere with an astronaut’s tasks. Additionally, space missions have strict safety protocols, meaning any accessory must be made from materials that are hypoallergenic, non-corrosive, and free of sharp edges to avoid damage to sensitive equipment or injury to the wearer.

Yet, astronauts have found ways to bring small, meaningful pieces into space, adapting them to the constraints of their environment. Jewelry in space often carries deep personal or symbolic significance, offering emotional comfort and a sense of connection to Earth.

Here are a few notable examples:

During the 1972 Apollo 16 mission, Command Module Pilot Ken Mattingly lost his wedding ring in the spacecraft. Days later, during a spacewalk, the ring was spotted floating out of the hatch. Remarkably, it bounced off Mattingly's helmet and was retrieved by fellow astronaut Charlie Duke.

Mae Jemison, the first African American woman in space, brought her signature earrings aboard the Space Shuttle Endeavour in 1992. This allowed her to showcase her heritage and individuality.

NASA astronaut Cady Coleman brought jewelry and art created by her husband, glass artist Josh Simpson, during her mission on the International Space Station from 2010 to 2011. These intricate glass pieces included miniature planets, representing a personal connection to loved ones back on Earth.

Astronaut and researcher Kellie Gerardi wore a stack of colorful friendship bracelets during her Galactic 05 research mission in 2023. She wanted to express her personality and femininity and broaden society's expectations of what an astronaut looks like. Inspired by Taylor Swift's Eras Tour, Kellie's "Astronaut Era" bracelets symbolized the support and love she received from her friends and family.

In 2017, French astronaut Thomas Pesquet flew a pair of wedding rings belonging to his friends to the International Space Station. He returned them to Earth in time for their wedding, adding a unique touch to their ceremony.

As we can see, even in space, jewelry can play an important and touching role.
