NASA’s next big space telescope is not only meant to unlock some of the mysteries of dark energy. It also is a pioneer in the naming of missions.
Scientific American recently said that the observatory, which launched on Aug. 30, is the first ever space telescope ever named after a real-life woman: American astronomer Nancy Grace Roman, who supported development of the iconic Hubble Space Telescope and was NASA’s first head of astronomy in the 1960s.
The story is very different when it comes to men. For example, NASA’s “Great Observatories,” which launched between 1990 and 2003, were all named after famous U.S. male astronomers or physicists: the Hubble Space Telescope (Edwin Hubble), the Compton Gamma-Ray Observatory (Arthur Compton), the Chandra X-ray Observatory (Subrahmanyan Chandrasekhar) and the Spitzer Space Telescope (Lyman Spitzer).
Indeed, relatively few spacecraft of any kind have borne female names over the years — and most of the ones that did were not honoring actual, real-life people.
For instance, a number of missions with female names took them from mythology (e.g., NASA’s Europa Clipper and China’s Chang’e moon probes). Others used female names not attached to particular individuals (such as NASA’s Clementine moon mission, and the European Space Agency‘s LISA, which is an acronym for “Laser Intraferometer Space Antenna.”)
A notable exception is Sojourner, the mini-rover on NASA’s Mars Pathfinder lander mission that was made famous again by the 2015 film “The Martian;” it’s named after Sojourner Truth, a Civil War-era abolitionist. Sojourner’s name was selected in 1995 from a worldwide naming contest for students and suggested by 12-year-old Valerie Ambroise of Bridgeport, Connecticut. Some other notable examples of missions honoring real-life women include:
- ESA’s long-delayed ExoMars rover Rosalind Franklin, which is now set to launch to Mars in 2028. It’s named after a British scientist who contributed to discovering the structure of DNA. (Part of the rover’s mission is to analyze potential biosignatures on the Red Planet’s surface.)
- The Cygnus International Space Station (ISS) resupply program, which is managed by Northrop Grumman. Multiple Cygnus freighters have been named after female NASA astronauts, including Janice E. Voss, Sally Ride and Kalpana Chawla, and one of them honored the American mathematician and “hidden figure” Katherine Johnson.
- Satellogic’s ÑuSat/NewSat series. It has commonly named satellites after female historical figures in science, such as Black American chemist Alice Ball, Polish physicist-chemist Marie Curie and Australian radio astronomer Ruby Payne-Scott.
- Canada’s GHGSat has a program in which employees name the company’s Earth-orbiting satellites after family members, which has generated names from real-life people like Eleonore and Penny.
- The U.S. Space Force nicknamed its GPS III Space Vehicle-08 “Ms. Creola Katherine Johnson,” another nod to the mathematician
What this means
Throughout history, the names of ocean-going ships — ships on the water, not spaceships — often have associations with women. The U.K.’s Imperial War Museums (IWM) suggests that women’s names are used due to two traditions. The first is that, very generally speaking, the word “boat” is a “female” word in some languages that use gendered nouns, but that is by far not universal, even among the imperial sailing powers of the 1400s to 1600s.
The second association, which seems more likely, is the notion of a mother, goddess or similar “female figure” guiding a crew, which we see in theaters right now with “The Odyssey:” Athena helps Odysseus, reflecting the ancient Greek epic story. (For example, figureheads — sculptures on sailing ship prows — were often, although not always, carved in the likeness of women, Royal Museums Greenwich states.)
There are famous sailing ships with female names that many Americans can cite, such as the nicknames for the three Spanish ships — the Niña, Pinta and Santa María — used by Christopher Columbus during his famed first voyage to the New World in 1492.
“There’s always been a tradition to name ships — and oftentimes after women,” Valerie Neal, emerita curator in the Smithsonian National Air and Space Museum’s department of space history, told Space.com. Neal’s research includes extensive work on female astronauts.
The U.S. space program has historically leaned upon mythological names of both genders for its missions, she noted, citing the Mercury, Gemini and Apollo human spaceflight programs as examples of male monikers. These days, Neal added, the education system is less tilted toward introducing children to old Greek or Roman myths, which may explain why it’s now more common to name missions after real-life individuals.
In the 1970s and 1980s, for example, “there was a big debate at the time of the space shuttle naming whether to name the space shuttles after historic figures, or after concepts,” Neal said. “One idea was even after Native American tribes.” (For example, Tafuna High School in American Samoa recommended the name “Hōkūle’a” for shuttle, as noted in NASA’s 1991 monograph “From Ship to Shuttle: NASA Orbiter-Naming Program”)
The space shuttles were ultimately named Columbia, Challenger, Discovery, Atlantis and Endeavour after “historic ships of exploration,” Neal said. You can read more about the origins of those names in this piece by The Space Foundation.
The Cygnus spacecraft “USS Janice Voss,” which flew to the ISS in 2014, was the first U.S. orbital mission known to Neal to be named after a woman. “She had had an affiliation with the Orbital Sciences Corporation, and so they wanted to honor her,” said Neal, referring to a previous company that managed the Cygnus program.
The flock of Cygnuses named after women — at least six of them, according to Neal — is “a good sign that people are starting to think of contemporary figures, or more contemporary, [and] naming spacecraft as a tribute to them, and to their contributions in science and exploration and discovery.”
Naming a flagship space telescope after Nancy Grace Roman is another good sign, of course. And choosing her for this honor makes sense; she was in “a class by herself — because her name is so directly associated with astronomy and large space telescopes” like Hubble, Neal said.
“It is recognizing her significance in the history of space exploration as a leader who made so much possible, through her own work as an astronomer, but then as an administrator and manager at NASA made possible the orbiting solar observatories, the orbiting astronomical observatories — and then Hubble and the other great observatories that followed.”
Roman’s name on the telescope, she added, is “elevated” because “her name coincides exactly with the spacecraft and its purpose, whereas the names of the astronauts that are attached to the [ISS] resupply missions … not all of them had any connection to the International Space Station. Several did, but not all.”
Neal said she’s hopeful that more women will see their names attached to space missions, including both those historical astronomers who saw “their bosses were getting all the credit” as well as the numerous non-male scientists making impacts in the field today.
“I think it’s entirely possible that, in time, there will be another major observatory named for a woman,” Neal added. She noted that recommendations from the science community every 10 years form the basis of new space missions, and that the next such “decadal survey” in astrophysics is expected to wrap up around 2030.
In the nearer term, NASA is considering ideas such as an ultraviolet telescope, an advanced X-ray imaging satellite, and the Habitable Worlds Observatory for launch in the 2030s or early 2040s, presenting more opportunities to attach female names to flagship space missions.
With thousands of flown or planned missions to space, and numerous parts making up each spacecraft, it is difficult to compile a comprehensive list of probes or instruments that have had female names. The following is therefore a partial list, though an extensive one. In no particular order, it includes:
- Telescopes/observatories: NASA’s Roman, ESA’s Gaia, NASA’s Pandora, the British-American Ariel V telescope, ESA’s NewAthena, ESA’s Ariel, ESA’s LISA, NASA’s TESS (Transiting Exoplanet Survey Satellite).
- Human spacecraft: Mercury Aurora 7, SpaceX‘s Crew Dragon Grace.
- Satellites/ISS missions: ESRO-1A and 1B’s nicknames of Aurora and Boreas, multiple Cygnus ISS resupply spacecraft, much of the Satellogic NuSat/NewSat constellation, several GHGSat spacecraft, Space Force‘s GPS III Space Vehicle-08 (nicknamed Ms. Creola Katherine Johnson), and the Russian Resurs-DK1 satellite’s multinational cosmic-ray module PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics).
- Moon: China’s Chang’e series, the Soviet Union’s Luna series, NASA’s Artemis program and missions, Intuitive Machines’ IM-2 lander Athena, JAXA’s Selene/Kaguya, NASA’s Clementine, the NASA ARTEMIS moon-orbiting probe.
- Venus: ESA’s Venus Express, the Soviet Union’s Venera series.
- Mars: ESA’s Rosalind Franklin rover, NASA’s Sojourner rover, JAXA’s failed Nozomi orbiter.
- Jupiter/moons: NASA’s Juno, NASA’s Europa Clipper.
- Asteroids: NASA’s Lucy, ESA’s Hera.
- Other hardware: Some spacecraft/rocket parts have female names (e.g. the US military’s Juno II rocket, Firefly Aerospace’s Miranda engine, ESA’s Europa and Ariane rockets).
The following at first glance appear to have female names, but either were not confirmed before this story’s deadline or were confirmed to have other origins:
- Japan’s MUSES Program (Mu Space Engineering Spacecraft), which may or may not reflect the English/Ancient Greek meaning of goddesses of knowledge.
- DoD’s ALEXIS (the Array of Low Energy X-ray Imaging Sensors) and JAXA’s Akatasuki (Venus Climate Orbiter) may not just reflect female names.
- NASA’s Uhuru, which is not named after the female “Star Trek: The Original Series” character but after the Swahili term for “freedom.”
- NASA’s Dawn is meant to reflect the solar system’s beginning, and not a person.
- The Soviet Vega series to Venus is meant to be VeGa, or as National Geographic once wrote, “a contraction of the Russian words for your dual targets, Venera and Gallei.”
