Revenge from the future: A temporal interference of the Space Race

This is an ASB timeline where a time traveler from our modern era goes back to the past and altered the course of the Space Race, to minimize Russian achievements during the period as a revenge for their invasion of Ukraine.
== Prelude ==
On February 24th 2022, Russia invaded Ukraine. During the summer, it turned into a stalemate which forced Putin to unleash a tactical nuke. This sent horrors around the world, but this would be bested when the world later found out that a SETI service has been abused to exhort aliens to threaten and attack Russia to stop the latter from "becoming the threat of the galaxy". Pandemonium ensued in Russia as many scramble to get out. To the full surprise of almost all humans, the threat was fulfilled when the aliens come.
Fast forward to 2030. The aliens have left, bringing along a human who wanted to go irrevocably with them alongside a space ark. The human would then enact a spiteful revenge against Russia, by travelling back in time through wormholes to 1957.
== Timeline ==
1957: The arrival of the time traveler on September 11st. After landing in spaceship, he commanded it to go back to hide in space while walking to New York City, where he was then immediately swarmed and arrested by NYPD officers due to being obviously strange-looking within the city. After claiming that he was a time traveler, the case was taken over by federal authorities. His claims about the impending launch of Sputnik on October 4 was then validated when it proceeded as in history. Wernher von Braun then got involved and instructed his personnel to believe him.
1958: The time traveler managed to get Pioneer 1 probe to the Moon and beyond; however fearing that divulging too much knowledge may cause the timeline to be more unpredictable, the time traveler decided to be very selective in doing that. Although this generated a lot of controversy, this course of action was reluctantly agreed upon.
1959: Soviet Union sent their first Luna probes to the Moon and captured images of the far side as usual. Fidel Castro took control of Cuba.
1960: Thanks to the time traveler's efforts, Mercury-Redstone 1 mission got off the ground.
1961: NASA's Alan Shepard is launched into space on March 9th, more than a month before Yuri Gagarin's flight into space. Despite being the first in space, they are soon wrecked by a sense of inferiority when USSR boasted about their "higher, better, further" flight. Hence, a race to the Moon soon followed. Later that year, Wally Funk became the first women in space, but again not in orbit.
1962: Mariner 1 probe's programming error was fixed in the last minute and thus launched into space. Kennedy made the Moon speech.
1963: Kennedy was incapacitated during the assassination attempt in Dallas. He then resigns the presidency and handed it over to the vice president. Valentina Tereshkova became the first woman to orbit the Earth. A sole primitive space station mission dubbed "Mercury-Atlas" is launched, with Alan Shepard, now one of the first men to enter space twice. 
1964: KGB got hold of intelligence that a time traveler was secretly helping the Americans to beat them in the space race. They then sent out agents to kidnap or kill him where they succeeded in incapacitating him instead.
1965: The NSA reluctantly orders the time traveler to go back into his spaceship, now at Area 51 and to fly into space to stop any Soviet pursuit attempts, with the condition that he may land again after a long time has passed. Alexei Leonov made first spacewalk.
1966: Different from OTL, a woman named Irina Solovyova made woman's first spacewalk.
1967: Apollo 1 caught fire and killed its crew. Soyuz 1 made a hard landing and permanently crippled Vladimir Komarov.
1968: Apollo 8 is the first manned mission to reach and orbit the Moon.
1969: Neil Armstrong is the first man on the Moon. Kennedy passed away later that year.
1970: Thanks to a forewarning by the time traveler, the Apollo 13 mission went as planned to the Moon and back. The Apollo missions went all the way to Apollo 20 before conclusion.
1975: Apollo Soyuz docking mission.
1981: Launch of Space Shuttle.
1985: Peace activist Samantha Smith lived all the way instead of dying, because of a warning by the time traveler left before leaving.
1991: Fall of communism in the Soviet Union. Secret documents about the "supposed" time traveler then leaked out, although it was dismissed as a conspiracy theory on the level of ufology then.
1996: Russia launched a probe to Mars.
2001: 9/11 attacks, however a day before the time traveler landed again on Earth, having exploited the theory of relativity to spend a long time. Although it was too late then, he incidentally averted the crash of Flight 93 when he warned a soon-to be victim about that, causing the terrorists in that plane to be arrested by flight marshals. The time traveler then went to his home country to stay hidden for the next 13 years.
2008: Summer Olympics in Beijing, China.
2014: Ukraine goes into civil war as OTL. The crash of the Malaysian Airlines flights 370 still happened. Wrecked with guilt, the time traveler turned himself in to the NSA. Because the risk of leak was judged to be "too high", he was then confined in secret bases. Malaysia Airlines 17 did not get shot down.
2015: The New Horizons space probe flew by Pluto. Ukraine war enters a frozen state.
2016: Hilary Clinton was elected as the President.
2017: North Korea conducts many underground nuke tests.
2018: US edged closer to a nuclear war with North Korea. This was then prevented when a maverick buyout plan to bribe their elites was put into action.
2019: Protests in Hong Kong, however it resulted in the fulfillment of some core protesters' demands and a milder national security law.
2020: COVID-19 outbreak, although it was far more limited due to advanced forewarnings by the time traveler and the development of novel antiviral treatments which isn't the case in OTL. As a result, the outbreak was treated akin to SARS or Ebola in OTL. Due to an economic slump, Putin begin to build up forces and threaten to invade Ukraine. A redux of this timeline's OTL 2022 then happened forcing him to back down. The time traveler and his counterpart would then leave the Earth in a similar fashion as OTL later.
