When will the total number of people who have gone to space reach 1000?
The first human in space, Yuri Gagarin, orbited the Earth once on April 12 1961. The most recent successful manned launch delivered Sergey Prokopyev, Alexander Gerst, and Serena M. Auñón-Chancellor to the ISS as crew. Of the three only Gerst had already flown in space before, rendering Auñón-Chancellor and Prokopyev the most recent astronaut/cosmonaut as of 8 June 2018. Before their return they’re expected to orbit the Earth almost 3000 times.
In the 57 years between Gagarin and Prokopyev/Auñón-Chancellor more than 550 people have flown to space. Cosmonauts, astronauts, taikonauts, even space tourists.
But when do you think there will have been 1000 humans in space?
For the purposes of this question we will only count people who have reached orbit. Sub-orbital flights are explicitly excluded.
Metaculus help: Predicting
Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.
The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available. With tachyons you'll even be able to go back in time and backdate your prediction to maximize your points.
The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.
Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.
Note: this question resolved before its original close time. You earned points up until the question resolution, but not afterwards.

Metaculus help: Community Stats
Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.
When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
