Will Parker Solar Probe survive its 24 loops around the sun while getting just a few million miles away from the surface of our star?

The Parker Solar Probe rocket lifted off from Cape Canaveral, Florida.

The probe is set to become the fastest-moving manmade object in history. Its data promises to crack longstanding mysteries about the Sun's behaviour.

Over the course of seven years, Parker will make 24 loops around our star to study the physics of the corona, the place where much of the important activity that affects the Earth seems to originate.

The probe will dip inside this tenuous atmosphere, sampling conditions, and getting to just 6.16 million km (3.83 million miles) from the Sun's broiling "surface".

"I realise that might not sound that close, but imagine the Sun and the Earth were a metre apart. Parker Solar Probe would be just 4cm away from the Sun," explained Dr Nicky Fox, the UK-born project scientist who is affiliated to the Johns Hopkins Applied Physics Laboratory.

"It will also be the fastest man-made object ever, travelling at speeds of up to 430,000 mph [690,000km/h] - New York to Tokyo in under a minute!" she told BBC News.

Resolution is positive if the Parker Probe is still transmitting valid data to Earth as of its 24th Perihelion, and at least some of those approaches have been within target specifications of the flight plan.

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.

Community Stats

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.
