mass over on Reddit are discussing an old urban legend that NASA cosmonaut are write out with nitril capsules – or other mean value designate to lend about death – in face they should find themselves in a situation where all hope of a yield to Earth was recede .

" believably a weird question but maybe someone has some insights ? A Friend and I were marvel if astronaut take anything like cyanide condensation or something in case that there is an emergency where they are front inevitable demise , " Reddit user ClinkzZ90said in their interrogation . " For model when there are serious problems with biography backup system ( atomic number 8 , water and so on ) or in scenarios like a nuclear war with no hope to get back to ground . "

The unforesightful result to the question is no : NASA does not issue suicide capsules . However , the first cosmonaut to conduct a spacewalk , Alexei Leonov , state that he was issue with such a oral contraceptive prior to his excursion .

allow ’s start with NASA . The US space agency has never sacrifice cosmonaut self-destruction pills in case missionary post go wrong . Jim Lovell – who commanded theApollo 13 missionary station – explain that in infinite , they are n’t really necessary .

" masses often say , ' did you take a self-destruction pill ? ' or something like that . You did n’t [ need ] those . All you had to do was crank afford the slight valve to the hatching there … open up up the little vent valve … " he explained , per Smithsonian’sAir & Space Magazine , referring to the Apollo 13 delegation .

" Never would ’ve call back about it [ on Apollo 13 ] until all Bob Hope was lost . And then our idea was , if all hope was lost , if we went by the Earth — say we missed the Earth , and we were on an scope about the sunlight , if we had exceeded the escape velocity … .My idea was to arrest off , you roll in the hay , as long as we had options , as long as we could stand it , send back data … .We likely would have been farther out than anybody . And then , you know , then we would decide , you know , what to do … .Maybe we would have all committed suicide by opening up the outlet valve . And that would have been the end of the deal . "

The rumor that NASA astronautscarry suicide pills may have come from Carl Sagan ’s novelContactor its cinema adaptation , in which the main eccentric is issued with such a pill .

However , there is at least one spacefarer who claims to have been given a contraceptive pill , in case their mission went awry . This wasAlexei Leonov – who , on March 18 , 1965 , transmit the first - ever spacewalk , impound to his ship only by a tether5.35 meters ( 17.6 feet)in length .

Though the Extravehicular Activity ( EVA ) was in the end a winner , in that he channel the spacewalk and returned safely , Leonov did not have what you ’d call a great time out there .

" Leonov ’s Berkut wooing ballooned , making bend difficult . Because of this , Leonov was ineffectual to reach the shutter transposition on his second joint for his chest - ride camera . He could not take pictures of Voskhod 2 , nor was he able-bodied to recover the photographic camera mounted on Volga which commemorate his EVA for posterity , " David S. F. Portree and Robert C. Treviño explicate in the bookWalking to Olympus : An EVA Chronology .

During the manner of walking , making matters worse , his sweat begin to slosh around his courting , with the spaceman stating he was " up to his knees " in exertion . After a 12 - minute EVA , he return to the spacecraft , but the risk was not yet over .

" late accounts say that he violated procedure by entering the air lock head first , then got stuck sideways when he call on to end the outer crosshatch . This forced him to philander with dysbarism ( the ' crimp ' ) by lowering his wooing pressing so he could bend enough to free himself . Leonov latterly revealed that he had a suicide pill he could have bury if he had been unable to ingress Voskhod 2 and Belyayev had been force to leave him in cranial orbit . "

No other cosmonauts have spoken about being issue with such a anovulatory drug . As outlined above , if a mission were to overshoot or otherwise become stranded , there are very easy way todie in space .
