Are you ready to take the risk of the International Space Station falling < p > subsequently, NASA did not directly respond to Rogozin's remarks, but said it would continue to cooperate with the Russian Federal Space Agency "to maintain the safe and sustainable operation of the international space station." < p > when Biden announced the "devastating sanctions" against Russia on the 24th, he said, "we estimate that more than half of Russia's high-tech imports will be cut off, which will attack their ability to continue to realize military modernization and weaken their aerospace industry, including their space program." < p > the briefing released by the White House on the same day did not specify the specific sanctions or restrictions on Russia's space program, but said that the United States and its allies would "ban the export of sensitive technologies throughout Russia, mainly aimed at Russia's defense, aviation and marine departments, and cut off Russia's access to cutting-edge technologies." The technologies involved include semiconductor, telecommunications, encryption security, laser, sensor, navigation, avionics and maritime technology. "These strict and continuous controls will cut off Russia's access to cutting-edge technology." The White House statement wrote < p > British Prime Minister Boris also questioned the future of the international space station in his speech on the 24th. "I have been widely supportive of continued artistic and scientific cooperation." Speaking in the house of Commons, he said, "but under the current circumstances, it is difficult to see that these conditions can continue to be normal." < p > after the United States announced the sanctions, Dmitry Rogozin, director of the Russian Federal Space Agency, sent seven tweets, entitled "sanctions for Alzheimer's disease"（ САНКЦИИ АЛЬЦ-ГЕЙМЕРА）” < p > he wrote: "Biden said that the new sanctions will affect Russia's space program. Well, we need to clarify the details: do you want to prevent us from obtaining radiation resistant space microelectronic equipment? You have done it in 2014, and as you have noticed, we are still building our own spacecraft. We will do this by expanding the production of necessary components and equipment at home Achieve this goal. " < p > "do you want to ban all countries from using the world's most reliable Russian rockets to launch their spacecraft?" Rogozin then asked, "you have done so. You plan to impose sanctions on our launch vehicles from January 1, 2023, and finally destroy the world space competitive market. We all know that this is not news, and we are ready to take action." < p > "do you want to destroy our cooperation on the international space station?" Rogozin then asked the third question, "you have done this by limiting the communication between our astronauts and American astronauts in the training center." < p > Rogozin also angrily criticized Musk's space X company, "your talented businessmen polluted the low earth orbit with garbage." Last December, China sent a note to the United Nations that the "star chain" satellite launched by the US space exploration technology company (SpaceX) approached the Chinese space station twice. For safety reasons, the Chinese space station assembly has implemented emergency collision avoidance twice < p > Rogozin reminded that the orbit and position of the international space station are controlled by the Russian engine, "if you prevent cooperation with us, who will save the space station?" Rogozin asked, "the international space station went out of orbit uncontrollably and fell into the United States or Europe? Another possibility is that this 500 ton building fell into India or China. Do you want to threaten them with such a prospect?" < p > Rogozin continued: "the international space station will not fly over Russia, so you bear all the risks. Are you ready?" < p > finally, Rogozin quipped: "gentlemen, when planning sanctions against others, please check whether those who formulate sanctions have Alzheimer's disease. Just in case, avoid sanctions falling on you." Rogozin reminded the United States: "as a partner, I suggest you don't act like an irresponsible player and deny the statement of 'sanctions for Alzheimer's disease'. Friendly advice." < p > it is reported that the international space station was jointly built by the United States, Russia, Japan, Canada and the European Space Agency. It is divided into two parts - the Russian orbital module and the American orbital module < p > NASA astronaut Garrett Reisman said: "the Russian segment can't work without the power of the US side, and the US segment can't work without the propulsion system of the Russian side. So you can't break up peacefully. You can't consciously separate." < p > at present, four American astronauts, two Russian astronauts and one European astronaut live and work in this orbital outpost < p > cnn25 reported that a NASA spokesman did not directly respond to Rogozin's remarks, but said that "we will continue to cooperate with all international partners, including Rosneft, to ensure the continuous and safe operation of the international space station." < p > in response to the latest US sanctions, a NASA spokesman said: "the new export restrictions will continue to allow us Russian civil space cooperation. NASA has no plans to change its support for on orbit and ground station operations. The new export restrictions will continue to allow us Russian civil space cooperation." < p > after NASA's statement, Rogozin also tweeted: "NASA confirms its willingness to continue cooperation with the Russian Federal Space Agency on the international space station. At the same time, we will continue to analyze the new sanctions measures of the United States to elaborate our response measures."
