When will a crewed spacecraft enter interstellar space for the first time?
For the second time in history, a human-made object has reached the space between the stars. NASA’s Voyager 2 probe, launched on August 20 1977, has now has exited the heliosphere – the protective bubble of particles and magnetic fields created by the Sun. The only human-made object to previously achieve this was Voyager 1, launched on September 5, 1977. Both of these craft are unmanned probes.
This question asks: When will a crewed spacecraft containing living and conscious human beings be confirmed to be outside of the Sun's heliosphere?
For the purposes of this question, the humans on the spacecraft must be both alive and conscious at the time that the spacecraft is confirmed to be outside the heliosphere. Humans in any kind of cryonic preservation, suspended animation, hibernation or other similar state at the time that the craft is declared to be outside the heliosphere are excluded, as are 'mind uploads' (a hypothetical futuristic process of scanning the mental state (including long-term memory and "self") of a particular brain substrate and copying it to a computer) that are hosted locally on the spacecraft, or any other kind of non-human consciousness.
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.
