Hundreds of animals have been launched into orbit because the daybreak of the area age. However to what extent have cats been concerned in such endeavors?
Within the days earlier than the primary astronauts had ventured into area, animals have been utilized by scientists to see whether or not it was potential for all times to outlive the consequences of spaceflight.
Animals have additionally been used to analyze numerous organic processes and the consequences of microgravity on these dwelling organisms.
A number of nations, together with the U.S. and Soviet Union, despatched animals into area. Among the many large number of creatures that have been launched into area—many in ethically doubtful experiments—have been canine, rodents, non-human primates, fish, frogs, spiders and bugs.
However have cats ever ventured into area?
What was the primary cat in area?
To this point, just one cat has ever made it into area—a feline dubbed Félicette who was launched into orbit in 1963 by the French area program.
Félicette—reportedly a stray picked up on the streets of Paris in keeping with some accounts—was certainly one of 14 cats chosen by the Centre d’Enseignement et de Recherches de Médecine Aéronautique (CERMA) for “coaching” to enter area.

This coaching concerned some testing in centrifuges and spending lengthy intervals of time in restraining clothes. The cats additionally had implants and everlasting electrodes positioned on them, Keith Crisman, a professor within the Division of Area Research on the College of North Dakota, informed Newsweek.
“This was France’s entry into the area race, making them the third nation to launch a civilian area company.”
Why would you ship cats to area?
The first purpose for utilizing the cats on the time was that nobody actually knew the impact of microgravity on advanced organisms like people.
“So, if the cats survived, it was assumed that people might as nicely,” Crisman stated. “These cats have been positioned in a number of—intense, I’d add—coaching conditions, which included compression clothes to forestall motion and even a high-g centrifuge. Additional, there have been loads of invasive assessments as nicely.”
French scientists finally narrowed down the group of 14 cats to 6 primarily based on their coaching conduct and general demeanor. Félicette was finally chosen attributable to her calmness and weight. Initially she was unnamed, merely designated with the tag C341. A backup cat, additionally unnamed, was additionally chosen.
On October 18, 1963 Félicette was launched atop a Véronique AG1 rocket from a web site in Algeria throughout the Sahara Desert. Throughout her journey, which lasted lower than quarter-hour, the cat reached an altitude of almost 100 miles, briefly experiencing weightlessness and forces of as much as 9.5 gs.
The cat managed to outlive the journey after the capsule carrying her efficiently indifferent from the rocket, parachuting safely again to the bottom.
What did scientists study from cats in area?
Through the coaching of the cats, electrodes have been positioned into their brains to permit for monitoring of neurologic exercise. This restricted their “coaching” to only some months to keep away from points with the electrodes.
“Talking of those electrodes, some have been set to observe neurologic exercise by means of placement in numerous places on the cranium and within the entrance sinuses, some have been positioned on both again leg to observe cardiac output, and two have been positioned on her entrance legs that may very well be used to stimulate electrical impulses for a response,” Crisman stated.
Félicette’s respiratory was monitored by a microphone on the chest and within the nosecone of the rocket. She finally spent round 5 minutes in microgravity but additionally skilled 9.5 gs on launch and seven gs on descent.
“To place that as compared, Shuttle astronauts skilled round 3 gs and the SpaceX Dragon experiences roughly 4 gs, much like Apollo astronauts on the Saturn V,” Crisman stated.
The info that researchers obtained indicated that the cat skilled an elevated coronary heart and respiration price on ascent and descent however this returned to a nominal price whereas in microgravity.
Regardless of surviving her extraordinary journey, Félicette was euthanized two months later—after she was named—in order that scientists might conduct additional research on her mind.
What number of cats have been in area?
Whereas Félicette is the one cat up to now that has made it into area, the French did additionally try and launch one other one of many feline cadets.
On October 24, 1963, a second launch was tried with a cat onboard however the rocket skilled a mechanical failure, taking pictures off at an excessive angle, with the animal perishing within the incident.
“The catstronaut didn’t attain area and because of the injury and size of time to succeed in her, succumbed to her accidents within the badly broken nosecone of the rocket,” Crisman stated.
All the remaining cats bar one have been euthanized on the finish of this system. The one one which survived escaped demise as a result of it had a response to the electrodes they usually have been eliminated. She was subsequently saved as a mascot for the group.

Within the Nineteen Forties, some cats have been utilized by the U.S. Air Power as a part of spaceflight analysis efforts. However these felines by no means made it into area. They have been utilized in microgravity motion assessments, which concerned inserting the cats on parabolic plane flights and releasing them. Scientists have been in a position to observe how they moved on this simulation of microgravity.
“On the time we had no thought if a human might even transfer in microgravity—there was additionally concern that their eyes might ‘fall out.’ So, the reply was to let cats free on the parabolic flight,” Crisman stated.
Félicette’s story has largely been overshadowed by these of different animals corresponding to Laika—a Soviet area canine who was the primary animal to orbit the Earth in 1957.
“Truthfully I believe plenty of that is because of the truth that the main focus was totally on the U.S. and U.S.S.R.,” Crisman stated. “Happily, Félicette does lastly have a memorial statue of her wanting as much as the sky.”
Following a profitable Kickstarter marketing campaign, a bronze statue of the cat was unveiled in 2019 on the Worldwide Area College in Strasbourg, France.
