Will the James Webb Telescope Launch prior to 2020?

The Hubble Space Telescope was launched into low Earth orbit in 1990 and, after a servicing mission in 1993 in order to correct the telescope's optics, it began delivering pictures of the universe of unprecedented quality.

The question of what Hubble's replacement should be was soon posed and in 1996 the planning for Hubble's successor, the James Webb Telescope, started.

Regrettably, the project became plagued by cost and schedule issues. The launch year was set to 2007 in 1997 with a budget plan for 0.5 billion dollars; currently the budget is set at 8.8 billion dollars and the telescope is scheduled for launch between March and June of 2019.

It is asked:Will the James Webb Telescope be launched prior to January 1st, 2020 at 00:00 UTC?

For positive resolution, the boosters of the rocket carrying the telescope must start firing before January 1st, 2020 at 00:00 UTC, rather than the telescope having to have arrived at the L2 Lagrangian point by that time.

The closing time for the question has been set, due to lack of a better idea, to the 49th anniversary of the Apollo 11 Moon landings.

Resolution shall be by credible media report.

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.

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.
