Twenty-seven asteroids have been named in honor of African American, Hispanic, and Native American astronauts, and one cosmonaut, who have helped expand our horizons beyond Earth and to inspire the next generation of space explorers.

Among the 27 people who inspired these new asteroid names are Stephanie D. Wilson, Joan Higginbotham, and Ed Dwight Jr., a captain in the U.S. Air Force who became the first African American astronaut trainee in 1961. José Hernández, who developed the first full-field digital mammography imaging system, also inspired an asteroid name.

The full list of astronauts and their namesake asteroids was released on February 23 by the Minor Planet Center, an organization affiliated with the International Astronomical Union (IAU), that’s responsible for the identification, designation and orbit computation for minor planets and other objects. Up until now, these asteroids had provisional names indicating their time of discovery. All 27 are located in the asteroid belt between Mars and Jupiter.

(103738) Stephaniewilson and (103739) Higginbotham were named after women who have made significant contributions to space exploration. On top of distinguished engineering careers, both were selected in 1996 to join NASA’s Astronaut Group 16, nicknamed “The Sardines” because of its large class size of 44 candidates.

As an electrical engineer at NASA’s Kennedy Space Center in Florida, Higginbotham worked on 53 space shuttle launches between 1996 and 2007. As an astronaut, she launched from Kennedy aboard the space shuttle Discovery to the International Space Station (ISS), where she served as a mission specialist on an assembly mission.

Wilson, an aerospace engineer, worked for several years at NASA’s Jet Propulsion Laboratory in Pasadena, California, as a member of the Attitude and Articulation Control Subsystem team for NASA’s Galileo spacecraft. After becoming an astronaut, she traveled to the space station three times, logging more than 42 days in space. Today, Wilson is on NASA’s Artemis Team of astronauts, one of whom will become the first woman to set foot on the Moon.

Consecutively named asteroids were chosen for Wilson and Higginbotham in a nod to the fact they were selected as astronaut candidates in the same class.

Asteroid (92579) Dwight was named after Ed Dwight Jr., who was born in 1933 in Kansas City, Kansas. He recounts in a media interview being stunned by a newspaper article profiling a black pilot, a revelation of unimagined possibility. This set him on his own pursuit of flight. After making it to the rank of captain in the U.S. Air Force, he was recruited to be the first African American astronaut trainee. In the astronaut program, he encountered deeply entrenched racism, was eventually forced out, and resigned from the Air Force in 1966. Dwight chose a wildly different path after this major setback, returning to his early love of the arts by reinventing himself as a sculptor of African American history. He created more than a hundred memorials globally and many thousands of other artworks.

José Hernández, the astronaut behind asteroid (122554) Joséhernández, was born into a migrant farming family and spent his youth working in the fields. When he was in high school, Hernández was inspired by Franklin Chang-Díaz, a long-time astronaut who flew seven space shuttle missions from 1986 to 2002. Hernández went on to receive bachelor’s and master’s degrees in electrical engineering, worked on X-ray lasers, developed the first full-field digital mammography imaging system, and then became an astronaut. Hernández traveled on the space shuttle Discovery to the ISS in 2009 on a mission to deliver a Multi-Purpose Logistics Module. Now asteroids (122554) Joséhernández and (115015) Chang Díaz can inspire the next generation of space explorers.  

“It’s an honor and a privilege to name these asteroids in recognition of fellow space explorers while also adding to the message of the power and value of diversity for all human endeavors,” said Marc W. Buie, an astronomer who discovered the 27 asteroids in the last couple of decades. Buie is a Boulder, Colorado-based astronomer at the Southwest Research Institute, which is headquartered in San Antonio, Texas.

Buie is also a co-investigator on NASA’s Lucy mission, which will launch atop the Atlas V 401 rocket from Cape Canaveral, Florida, on October 16, 2021. Its 12-year mission — the first of its kind — is to study seven Trojan asteroids that are among the two swarms of space rocks that circle the Sun, leading and following Jupiter in its orbit. Lucy will also fly by one main-belt asteroid.

The asteroid-naming proposal to the IAU, an organization that approves and certifies the names of astronomical objects and features, was a team effort by scientists and students involved with Lucy. It was led by Cathy Olkin, deputy principal investigator of the Lucy mission at Southwest Research Institute, and Keith S. Noll, a planetary astronomer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, who serves as Lucy project scientist.

“Last summer a group of us got together to honor a diverse group of astronauts who have traveled to space and the pioneers who paved the way for these explorers,” said Olkin. “But there are many more, and we hope to add their names to the sky in the future.”

Besides Olkin and Noll, the research and citation writing group included Katherine Kretke, Lucy communications lead; Carly Howett, Lucy instrument scientist; Donya Douglas-Bradshaw, Lucy project manager; Edward ‘Beau’ Bierhaus, Lucy scientist; Jake Olkin, graduate student at University of Michigan; and Zach Olkin, undergraduate student at Georgia Tech.
