In 1992, scientists sent 230 hornets into space to see if they could build a nest without gravity; after 8 days, they returned without building oneDuring a 1992 space mission, the Endeavour shuttle became home to 230 hornets, prompting scientists to investigate how these insects build ...- In 1998, scientists sent 4 pregnant swordtail fish and 200 babies into space; near the end of the mission, the fish suddenly began swimming in continuous loopsIn an unprecedented experiment in 1998, swordtail fish were launched into orbit on the space shuttle Endeavor to explore how life persists ...
- In 1983, three pregnant guppies flew on Cosmos 1514 for five days; one later gave birth to 25 healthy fry and produced six more healthy broods after returning to EarthIn 1983, three expectant guppies journeyed aboard the Cosmos 1514 biosatellite as part of a Soviet experiment exploring the effects of micr...
- In 2019, Nickelodeon sent green slime to the ISS for eight demonstrations; the tests offered insights into liquid containment and hydroponic plant watering researchAstronauts on the International Space Station engaged in a fascinating experiment with Nickelodeon's iconic green slime. This unexpected pr...
- In 2024, ESA flew bouncing hexapods to 256 km on a Swedish sounding rocket; six minutes of microgravity showed how complex grains collide and transfer energyA Swedish rocket successfully launched miniature brass crosses designed for microgravity research. Scientists are investigating how these i...
- In 1997, NASA grew Brassica rapa on Mir for 122 days to test a full life cycle; seed-to-seed cycles succeeded, but space-grown seeds were smallerIn an exciting development, researchers have achieved seed-to-seed cycling of plants in microgravity environments, demonstrating gravity in...
- In 1979, Cosmos 1129 flew five female and two male rats for 18.5 days and allowed them to mate; no normal pregnancies resulted in flight, while a later ground study produced healthy littersCosmos 1129, a Soviet biosatellite, conducted groundbreaking research on rat reproduction in space. Through ground simulations that mimicke...
- In 2015, fruit flies were sent to International Space Station to study how microgravity and the space environment affect the innate immune systemIn 2015, fruit flies were sent to International Space Station to study how microgravity and the space environment affect the innate immune ...
- Scientists made gravity act on an atom in a quantum superposition — the surprising result could bring Einstein’s theory and quantum physics closer togetherPhysicists have directly linked quantum mechanics and Einstein's gravity theory. An experiment used ultracold atoms in quantum superpositio...
- In 1994, NASA flew four Japanese red-bellied newts on STS-65 for nearly 15 days; two adults died, but 32 newt eggs hatchedSpace Shuttle Columbia's 1994 mission studied animal reproduction in zero gravity. Four red-bellied newts and medaka fish were part of biol...
- In 1958, a mouse nicknamed Minnie Mouse was sent to space by the United States Air Force under the first Mouse-in-Able (MIA-1) mission aboard a two-stage Thor-Able rocket but the animal didn't survive the flightIn 1958, a mouse nicknamed Minnie Mouse was sent to space by the United States Air Force under the first Mouse-in-Able (MIA-1) mission aboa...
- In 1994, 300 young male fruit flies flew for 14.5 days on IML-2; repeated video showed their locomotor activity rose sharply while they were in microgravityIn 1994, fruit flies were launched into space, revealing significantly heightened activity levels in microgravity. These flies aged more ra...
- In 1951, two female stray dogs named Dezik and Tsygan became the first mammals to successfully cross the border of space and return aliveIn 1951, two female stray dogs named Dezik and Tsygan became the first mammals to successfully cross the border of space and return alive. ...
- In 1961, Liberty Bell 7 sank after Gus Grissom's flight; 38 years later, crews recovered the capsule from more than 15,000 feet beneath the Atlantic OceanFor thirty-eight years, astronaut Gus Grissom's Liberty Bell 7 spacecraft lay lost beneath the waves. A skilled salvage expert ventured int...
- In 1970, NASA launched two bullfrogs into orbit to study vestibular function; over six days, the animals provided hours of data on balance in weightlessnessIn 1970, an extraordinary experiment sent two frogs, Pierre and Tee-Nom, into orbit around Earth. Researchers closely examined their inner ...
- In 1966, NASA launched Biosatellite I with 13 biology experiments and more than 10 million organisms; its retrorocket failed, and the spacecraft was never recoveredIn 1966, NASA's Biosatellite I mission attempted to carry over ten million organisms into orbit, but a retrorocket malfunction led to the c...
- In 1967, NASA flew flour beetle pupae on Biosatellite II for 45 hours; radiation and weightlessness raised wing abnormalities in flight from 29.9% to 44.8%During the 1967 Biosatellite II mission, flour beetles displayed notable wing deformities, underscoring how weightlessness amplified the ad...
- In 1947, the military sent fruit flies 67 miles into space to test radiation risks. 11 years later, NASA was founded in 1958, with animal flights underway in America now1947 mission was part of a larger American effort to understand whether living organisms could survive the journey into space. Beginning in...
- In 1967, Biosatellite II irradiated parasitic wasps for 2 days in orbit; females later laid as many eggs as controls, and hatchability remained excellentA 1967 NASA mission sent parasitic wasps into orbit around Earth. These wasps showed surprising resistance to radiation damage while in spa...
- In 2005, NASA flew five thick-toed geckos aboard Foton-M2 for 16 days without food or water; all were recovered with no apparent negative health effectsFive geckos orbited Earth for sixteen days without food or water. Researchers studied how weightlessness affects these cold-blooded animals...
