Animal spaceflights paved the way for the first human astronauts, and today, creatures big and small continue to space travel, advancing our knowledge of how the zero-gravity environment impacts all beings and aiding research down on Earth.
Supercluster.comâs Astronaut Database is a compilation of every human and creature with a spaceflight experience. Chief creative officer Jamie Carreiro worked to compile all the non-human space travelers, which includes hundreds of fruit flies, 40 dogs, 30 primates, seven bats and one cat.

âWeâre the ESPN for space,â Carreiro said of Supercluster.com. âLetâs say youâre a baseball fan -- you want to look at the stats of that pitcher, or you want to see how many three-pointers your favorite NBA star got to provide context for a story, we want to create that same kind of presence for space travelers, for astronauts (and) for researchers in the long term.â
Recent entrants to the database include NASA Astronaut Victor Glover following his first spaceflight in the SpaceX Dragon spacecraft; also Gloverâs crew mates, Mike Hopkins, Shannon Walker and Soichi Noguichi -- and a Baby Yoda doll that the SpaceX Crew-1 astronauts brought along with them.
By popular demand, the site now also tracks the plush toys used as zero-gravity indicators by astronauts.

Carreiro said the Supercluster database team quickly realized it couldnât tell the story of human spaceflight without including the first living beings to go to space.
When spaceflight was still a concept, NASA and the then-Soviet Union first sent up primates and dogs. These animals were subjected to vigorous testing and often cruel treatment as humans attempted to learn what they could from them in order to leave Earth.
âEven if they couldnât choose to make the sacrifice, they are akin to those explorers who may have tried to cross the Arctic, and that made it, and you know, we can honor them, similarly, even if they didnât make the choice,â Carreiro said.
Only one cat named FĂŠlicette, of France, ever achieved spaceflight. Carreiro said people can draw their on conclusions as to why felines werenât used again.
âWe jumped immediately to dogs and primates because we wanted to get close to higher-order mammals to try and figure out like, âOK, can we send a person up there?ââ Carreiro said.
Without the monkeys, apes and dogs, Carreiro said there would be no first human spaceflight by Russiaâs Yuri Gagarin or first American spaceflight by Alan Shepard.
âThose stories are such a mix of optimistic and happy, and also a little bit tragic, frequently, because the animals canât give their consent, and because they donât always come back,â Carreiro said.
In the Soviet Union, the dogs sent to orbit in the 1950s and 60s werenât well-known breeds. Instead, the Russians used strays.
âMost of them were just street dogs because the logic being that if we pick up a mutt on the street, itâll probably be hardier both genetically and in its attitude. Itâll be more able to deal with different stimuli and unusual situations,â Carreiro said of the first space dogs.
The dogs often became the pets of the scientists who trained them, spending time at their homes and playing with their children, which presented a problem when they didnât return.
The first dog launched by the Soviets, Laika, actually did not return alive.
âAt first, the Soviet Union covered it up and they said, âThis dog is alive and well,â for days, but it likely had died within two hours of the launch,â Carreiro said, adding that was especially hard on the scientists who had developed a connection to Laika. âOne of the scientists kissed it on its nose just as they were closing the capsule, and that dog didnât return.â
After, the Russians improved life-support systems and many other dogs repeatedly went to space, returning home.
During one Soviet mission, a spacecraft with two dogs inside was meant to acquire a signal from another spacecraft flying by, but before that could happen, the space dogs alerted engineers to the approach.
âThe dogs in the capsule were barking because they had seen the capsule outside the window. And they were like, âOh my god, there it is.â So (it was) like a dog with a mailman, or the delivery truck or whatever,â Carreiro said. âThere was just this truth to that of like, âOh, yeah, we sent dogs to space, and theyâre still dogs. Theyâre still doing dog stuff ... thereâs someone at the window, who is that?â and they are protecting their spaceship.â
The record for most spaceflights by a living thing is actually shared by two humans and a dog, because a dog flew seven times during the Soviet era, and no human has beat that record yet, Carreiro said.
Fast forward about 50 years past the first achievements in human spaceflights: Animals that now go to space stay on the International Space Station as part of ongoing research happening inside the orbiting laboratory. This category includes mice, rats, ants, fruit flies and spiders. These creature stories are sometimes harder to track down, Carreiro explained.
âMany of the entries weâre seeing in here are drawn from research papers, where we know that an experiment was done in space. And then we go to the research paper to find out the population of insects that that experiment was run on,â Carreiro said. âSo, some of these entries, youâll see like, 15 harvester ants that most likely was recorded as part of an experiment, and then we go in and find that thatâs what had to be there.â
The spiders who have lived on the ISS were a little easier to learn about, including a red-back jumping spider called âNefertiti the Spidernaut.â
In 2012, an 18-year-old student from Egypt wanted to know if a jumping spider would be able to catch its prey in zero-gravity. His experiment was selected as part of an international competition. It turned out Nefertiti could hunt in space, no problem.
After launching from Japan on a cargo supply mission to the ISS, NASA astronaut Suni Williams oversaw Nefertitiâs experiment.
âI think sheâs been eating well,â Williams told the students and celebrity scientist Bill Nye in a 2012 video.
âI saw her stalking a fruit fly, unbeknownst to that poor little fruit fly, and she was looking at it and she was going real close, and all of the sudden, *Chook* she jumped right on her, and it was amazing!â Williams said. âI think the spiders absolutely adapted in space. It was incredible to watch.â
Many of the insects launched to the ISS live out their short lives there, but Nefertiti came back to Earth and lived out her days at the Smithsonian.
Nefertiti was only expected to have a lifespan of about a year. When she died in December 2012, NASA wrote a moving obituary for the jumping spider that included references to âCharlotteâs Webâ and key moments in her short life.
âNefertiti didnât spin a web like Charlotte; her kind never could. But the red-back jumping spider earned a classy nickname, Spidernaut, as well as a bunk at the popular Insect Zoo of the National Museum of History of Washington for her out-of-this-world exploits,â the post read.
But Nefertiti is far from the only arachnid to visit the space station, and definitely not the last insect or mammal to achieve spaceflight.
The first space dogs live on through their descendants today. The strays who survived were tremendously famous, and their puppies were highly sought-after. Soviet leader Nikita Khrushchev gifted President John F. Kennedy a dog named Pushinka, whose mother, Strelka, was one of the first dogs to fly into space.
