Looking back on all of humanity ’s success in space , it can be easy to block that many of our accomplishments have been built on the forfeiture of other beast . Here are ten animals who played an essential use in paving the inter - planetary way to space .

10 . Fruit flies
If we ’re going to tattle animals in outer space , it makes good sense to start with the first — and that title goes to none other than the unassuming fruit fly sheet . A act of them were launched aboard an American V2 rocket on February 20 , 1947 to search the effects of radiation syndrome on space - make out organisms .
The astro - flies ’ Eruca sativa was launched to an EL of 68 miles ( the United States and outside definitions of “ the edge of blank ” are 50 miles and 62 miles , severally ) before returning to Earth , at which point the fly sheet were recuperate alive .
9 . Dogs
It would be derelict of us , of course , to go away dogs off this list — and meet as we just got done talking about the first beast in space , it bear cite that the first animal in Earth ’s orbit was , in fact , a frankfurter .
Laika , show here , was a stray - turn - Soviet space bounder found aboard Sputnik 2 on November 3 , 1957 . regrettably , Laika was also the first fauna to choke in space , dying due to overheating just a few hours after enter range — a fact that has haunted some Soviet scientists ever since :
“ sour with beast is a reservoir of tolerate to all of us , ” enounce former Soviet scientist Oleg Gazenko ( one of the scientist responsible for sending Laika into blank space ) at a Moscow News conference in 1998 . “ We treat them like baby who can not speak . The more time passes , the more I ’m grim about it . We should n’t have done it … We did not take enough from this mission to justify the dying of the dog . ”
8 . Cats
But the Soviets were n’t the only ones to get off strays skywards ; in 1963 , France had every intention of send out a stray name Felix into space . Felix , however , had other plan , and flew the coop prior to the October 18th launching date . Felix was replaced by a female stray dubbed Félicette ( sport here looking very stepford - pussycat , probably on business relationship of the electrodes that were implanted in her brain to supervise her in - flight neuronal impulse ) .
Unlike Laika , Félicette never enroll Earth orbit . Her mission was to simply trip into blank and fall to Earth by parachute , and lasted less than 15 minutes . That said , Félicette was also recovered live .
7 . spider
The first arachnids in space were European garden spider named Arabella and Anita . The pair were launch on July 28 , 1973 aboard the Saturn IB rocket , in the US ’s second manned delegacy toSkylab .
Once in area , scientists monitored Anita and Arabella to see what effect being in Earth ’s orbit would have on their web - spinning ability . Pictured here is the first wanderer web to be spun in space , get by Arabella . All thing look at , she did a moderately bang - up job ( although the heaviness of the silk was found to vary significantly throughout the web — a feature article not bump in Earth - birl spider bodily structure ) .
6 . Bullfrogs
In 1970 , NASA launch itsOrbiting Frog Otolithspacecraft , with the main destination of gathering data on the effects of weightlessness on the brain ’s perception of gravity and acceleration in quad ( your otolith is part of the scheme your internal pinna uses to keep you balanced ) .
information gathered from electrode implanted in the bullfrogs ’ thoracic cavities and vestibular nerves ( your vestibular system plays a vital role in your sense of balance ) revealed that the initial time period of weightlessness lead to abnormal vestibular responses , but that these changes eventually revert to normal , suggest that the bullfrogs ultimately acclimated to their zero - g environment .
5 . The Russian tortoise
The first tortoise in space were a duo of Russian tortoises that were launched , fittingly enough , by the Soviet Union in 1968 . What micturate their escape especially remarkable , however , is that it was really a circumlunar one ; the Zond 5 spacecraft on which they were stow aside really flew around the Moon and back to Earth , making planetfall in the Indian Ocean . That means these minuscule badasses were two of the first creature to ever enter mystifying space ( joining the pair on its epic journeying were wine flies and mealworm … but let ’s be dependable , the existent hero here are the tortoises ) .
And safe of all ? They last the trip . What I ca n’t find info on is whether they ’re still live today — but seeing as Russian tortoises have life span of about 75 years , it ’s certainly potential .
4 . Rabbits
The first rabbit in distance , like the first tortoise , was also launch on a Soviet military mission . Marfusha , pictured here looking plucky alongside two of her in - flight companions , was launched on a gamy - height run flight on July 2 , 1959 , aboard an R2 - A rocket . All three beast were find animated .
feature here is a series of Haiku tributes to Marfusha , “ The People ’s Bunny , ” by musician John Talley - Jones . Apart from the svelte thrusting at Laika , they ’re pretty awesome .
3 . Newts
The Pleurodeles waltl species of newt , figure here , has been studied in distance on at least six missions , and on some of the most interesting , as well . In 1985 , the USSR ’s Bion 7 mission launched ten newts with amputated forelimbs into blank for the purpose of hit the books an organism ’s voltage for retrieval from injury in space ( newts were a proficient organismic mannikin because they possess the ability to mature entirely new tree branch ) . Incredibly , the newts were discover to regenerate importantly faster in blank than they do here on Earth .
2 . Pan troglodytes
The story of infinite travel has seen numerous Pan troglodytes launched to infinite , but the very first was Ham , visualize here strapped into his biopack couch before being found in an American Mercury capsule on January 31 , 1961 .
Ham ’s mission was different from that of just about every other organism on this list because he was actually civilize to mesh lever tumbler during his delegacy , and his power to do so efficiently while in flight demonstrated the feasibleness of sending a person to blank space .
1 . Water Bears
water supply bear are also known as tardigrade , but why would you ever go by tardigrade when you could go by “ water bear ” ? These water - dwelling microorganism have eight branch , measure less than 1.5 millimeters in distance , and are , all affair considered , probably the audacious animal we ’ve ever sent into outer space .
face in pointedness : in September , 2007 , H2O bear were launch into low-spirited Earth orbit on the ESA ’s FOTON - M3 mission where they were exhibit to the vivid radioactivity and vacuum of blank space FOR TEN daytime . When the water bears were render to Earth and rehydrated,68 % of them were revived — in the process becoming the first fauna to outlast the vacuum of space .
