You may have noticed that relations between the Russian space agency Roscosmos and NASA have acidify slightly in the last few workweek , largely due to threats made by the head word of Rosmoscos tocrash the International Space Station ( ISS ) into Earth ,   the Russian space federal agency   restrain thelaunch of OneWeb to ransom , and   — first and foremost   — the intrusion of Ukraine by Russian military force .

NASA as an organization has been tranquil and verify during the tension , stressing cooperation on the ISS as well as other projects . However , retired American astronaut Scott Kelly , free from having to be diplomatic , has reply to the head of Rosmoscos with a bigger burn mark than his space ships receive on re - accounting entry .

On Wednesday ,   Roscosmos lead Dmitry Rogozin pinch out a video of flags being removed from Russian roquette .

" The launchers at Baikonur decided that without the flag of some countries , our rocket engine would look more beautiful , " Rogozin say , as per Twitter ’s translate function .   With the reply being turned off , outer space veteran Kelly responded in a inverted comma tweet , telling him " Dimon , without those signal flag and the alien exchange they bring in in , your quad programme wo n’t be worth a darn . Maybe you’re able to find a job at McDonald ’s if McDonald ’s still exists in Russia . "

Former astronautGarrett Reismanalso chipped in , tweeting"Rogozin has always been a fool . Only now he in reality mortally wounds Roskosmos and end one of the few remaining sources of up-to-dateness for Russia . Keep this in brain when your ATM is empty . It will need a trampoline soon . "

A   Twitter user then involve what Reisman made of the situation on the ISS .

" Not many virtual choice there since despite the late low - budget Rogozin fantasy video , " he responded , referring to astrange and vaguely threatening videoreleased by Russian affiliated media of the ISS being dismantled . " Either side pulling out would basically ensue in the close of the ISS . And without the ISS , what is leave for Roscosmos ? "

Meanwhile , Kelly appears to have been blocked by Rogozin for the stuff shot .
