When will 100 people or more be in space, or on any astronomical body other than earth, simultaneously?
As of September 2019, the record for the greatest number of humans in space at one time is 13. This has happened three times, once in 1995, and twice in 2009.
This question asks: When will 100 people or more be in space, or on any astronomical body other than earth, simultaneously?
This question resolves as the date when it's first true that 100 people or more be in space, or on any astronomical body other than earth, simultaneously. For the purposes of this question, a living human will be considered to be 'in space' if they achieve an altitude of at least 100km above Earth's mean sea level, or if they are located on any astronomical objects other than Earth.
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.
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.

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.
