Delayed Vostok I

Overview
In OTL Vostok I human spaceflight mission was nearly undone and delayed by a wonky door and an overweight spacesuit. What if the delay did happen?

Timeline
Early 1961: Due to the Vostok I space capsule's wonky door and the overweight spacesuit, Sergei Korolev decides to postpone the human spaceflight mission. Point of divergence.

May 5, 1961: U.S. astronaut Alan Shepard became the first man in space after being launched into a suborbital trajectory in the Freedom 7 capsule.

May 12, 1961: The Vostok I mission finally flew with Yuri Gagarin as the first person to orbit the Earth.

February 20 1962: John Glenn is the first American in orbit.

July 22 1962: NASA's Mariner 1 is successfully launched to fly by Venus.

1964: Leonid Brezhnev took USSR's helm.

1965: Alexei Leonov is the first person to conduct a space walk.

1966: USSR cosmonaut Irina Solovyova became the first woman to conduct a spacewalk in the Voskhod 5 mission. Meanwhile Soviet's Luna 9 became the first spacecraft to soft land on the Moon. On the other side of the Atlantic, USAF launched the boilerplate of the Manned Orbiting Laboratory (MOL) space station into orbit, which was labelled OPS 0855.

1967: In this TL the Soyuz 1 tragedy didn't happen at all.

1968: Apollo 8 flew around the Moon as in OTL.

July 4, 1969: The test firing of Soviet N1 rocket is successful.

July 20, 1969: NASA astronaut Neil Armstrong is the first human to land on the Moon.

September 1969: Test flight of MOL 1 which was a first unmanned Gemini-B/Titan IIIM qualification flight (Gemini-B flown alone, without an active MOL)

February 1970: MOL 2 the second unmanned Gemini-B/Titan 3M qualification flight (Gemini-B flown alone, without an active MOL) is launched.

October 1970: A Soyuz 7K-LOK spaceship carrying Yuri Gagarin and Vladimir Komarov flew around the Moon. This alone caused a major shock to Americans regardless of Apollo 11.

December 1970: The U.S. launched the world's first space station with James Taylor and Albert Crews as the station crews who will stay on orbit for 30 days.

April 1971: USSR launched their first space station Salyut 1.

October 1971: Alexei Leonov became the first Soviet citizen to step foot on the Moon after landing with an LK (Lunniy Korabl) spacecraft.

1972: USSR launched the second manned lunar landing mission to the landing site of Luna 9 spacecraft.

1973: USSR launched the third lunar landing mission which made Irina Solovyova to become the first woman on the Moon.

1974: Unlike in OTL, NASA launched Pioneer H into the interstellar space. USSR landed a man in the lunar south pole.

1975: An Apollo spacecraft docks with a Soyuz spacecraft, marking the end of the Space Race.

1981: NASA launched the first space shuttle "Columbia".

1984: Soviet space probe Vega 1 flew by Halley's comet.

1988: Soviet space probes Phobos 1 and Phobos 2 is successfully commenced in this TL.

1989: NASA interplanetary probe "Galileo" is launched to Jupiter.

1996: NASA Mars probe Sojourner is launched.

2003: Europa Orbiter is sent to the namesake Jovian moon with the aid of a Space Shuttle. Concurrently NASA launched Deep Space 4 to comet Tempel 1. Unfortunately the Columbia space shuttle tragedy happened as in OTL.

2008: The Large Hadron Collider went online.

2010: In this TL NASA's Constellation program is not canceled by the USA. Japanese spacecraft IKAROS became the world's first interplanetary solar sail spacecraft.

2011: NASA retired its space shuttle fleet.

2016: Donald John Trump is being elected as the President of the United States. Exoplanet Proxima Centauri b is discovered. NASA launched Neptune orbiter to the gas giant.
