The Tianzhou-2 cargo spacecraft successfully docked with the core module of the tianhe ship launched earlier in the early morning of May 30, sending several tons of materials to the Tiangong space station, and then the manned spacecraft Shenzhou XII will be launched this month, and the three astronauts will be sent to the Tiangong space station and will launch a three-month residency mission!
Can humans reproduce in space?
With the official launch of the construction of China's space station, a large number of popular science articles on space and space stations have attracted a large number of readers, and in these reader groups, there is a topic of super high attention, that is, can humans reproduce in space? Then the next question is whether countries have carried out reproduction plans in space?
From the perspective of human reproductive principles, does space support reproduction?
On July 31, 2020, a paper published in Science Advances said that the movement of male sperm swimming towards the egg is a confusing spiral, a way of swimming with minimal energy consumption, completely unlike the up-and-down swing pattern that scientists took for granted before!
The distance of sperm swimming is only a few tens of centimeters, but its length is only 50-60 microns, which is no less than an abnormal marathon, and only the first place can be combined with the egg, and I have to admire that it is indeed the best and the best luck sperm can get this privilege!
The microgravity environment in space, the sperm swim is obviously smoother, although the help is very limited, but it is always positive, so does the space environment really help men and women to conceive when reproducing?
The first question is whether the eggs can appear as scheduled? The time for eggs to wait for sperm is not long, so it is necessary to appear in the appropriate place at the right time, but the time of female ovulation is not fixed, it will be greatly affected by the external environment, and the space microgravity environment will affect the female ovulation period, so this is the first obstacle!
The second obstacle is the male problem, NASA aerospace physiology expert Wolpe has said that men in the weightless state of blood distribution equally, compared to the Earth is less likely to physiologically react, and male hormones will also begin to decline after leaving the atmosphere, which is another obstacle!
The third problem is how the two parties in a microgravity environment can be together, because in this state, even a small reaction force will be far away, so there has been a possibility of testing the two together! But according to Italian-American writer Vanna Bonta and her husband, who have simulated on a gravityless plane in Europe, even with the assistance of restraint belts and Velcro, the operation is still very difficult!
Sex in space, where have we come?
In June 2015, Pornhub(P), the world's largest sharing site, launched a crowdfunding project on its official website, with the aim of raising $3.4 million in 60 days, asking Johnny Sins and Eva Lovia to stage a Sexploration.
But unfortunately, only 236086 dollars was completed, 6% of the target was completed, and the zero gravity aircraft of the European Space Agency was almost the same, and it was exempt from going to space!

The civilian copycat troops failed, so how is the national team fighting?
In May 2007, the British "Guardian" revealed a shocking news that shocked the world, the famous French popular science writer Pierre Kohler in the "Final Mission Mir: Human Adventures" described NASA in 1996 to complete the Sex in space mission, and the completion of this mission is STS-75!
But it is a pity that this is a oolong message, because the 7 astronauts who flew in the STS-75 voyage mission are all men, if the news is true, is the amount of information contained in it a bit large? However, the problem is that the requirement of reproduction is a physiological function, which is by no means what "large amount of information" can contain!

But there was a great opportunity to try a mission in history, and the only time in about 60 years since the launch of the spacecraft by humans, because in this mission, a couple of astronauts flew into the sky together!
Did the astronaut couple test it?
The astronaut couple, Mark C. Lee and Jan Davis, were assigned to the same crew on the STS-47 mission, with Mark Lee as the Payload Commander (PLC) and Jan Davis as the mission specialist.
At 10:23 a.m. on September 12, 1992, the STS-47 mission of the space shuttle Endeavour took off from the Kennedy Space Center to the space station. As early as the 1980s, NASA stipulated that astronaut couples could not fly together, of course, this was to prevent accidents, but Mark Lee and Jan Davis were secretly married a few weeks before the launch, and NASA wanted to redistribute at this time, it was too late, so they had to let them fly together!

The mission includes biotechnology, electronic materials, fluid dynamics, and human health in the life sciences, cell division and hatching of frog eggs, etc. Of course, this mission is also an excellent human reproduction experiment, because they are legal couples, but NASA strictly refuted the rumors of human reproduction experiments in this mission!
And pointed out that although the space shuttle is much more spacious than the spacecraft, the internal space can not do such a behavior to maintain privacy, and reproductive experiments also have great difficulties, so there is no intimate behavior during the mission!
Mark Lee and Jan Davis later divorced for some reason, but both couples refused to answer the intimacy during the mission! According to the speculation of the good people, in fact, their refusal to answer is originally an answer, but everyone can't know the details, and there is no scientific data disclosure!

In addition to the United States, of course, there is Russia in the national team, but in April 2011, Valery Bogomolov, deputy director of the Moscow Institute of Biomedical Problems, said:
There is no official or unofficial evidence of the existence of sex in space experiments in the Soviet Union or Russia.
As the third oldest manned spaceflight, China started the latest, but made the fastest progress, and is building the Tiangong space station, so will there be space reproduction experiments in the future? Friends with ideas can leave a message!
