Will the Hubble Telescope resume operations in its three-gyro configuration before the end of 2018?

On Friday, October 5th the Hubble Telescope was placed in Safe Mode because one of the gyroscopes it uses to direct and stabilize its movement failed. This was not unexpected as this particular gyro had been exhibiting end-of-life behavior for the past year. Two similar gyros have already failed. Back in 2009 six new gyroscopes were installed, and the remaining three are enhanced. An Anomaly Review Board is currently investigating the issue.

From NASA:

If the outcome indicates that the gyro is not usable, Hubble will resume science operations in an already defined “reduced-gyro” mode that uses only one gyro. While reduced-gyro mode offers less sky coverage at any particular time, there is relatively limited impact on the overall scientific capabilities.

As of question creation, the Hubble Telescope is still in Safe Mode. NASA seems confident that it will exit Safe Mode and resume scientific operations soon.

Will the Hubble Telescope resume operations in its three-gyro configuration before the end of 2018?

If the Hubble Telescope resumes three-gyro configuration for any duration of time and thereafter ceases that configuration—to enter reduced-gyro mode or for any other reason—the question still resolves positive. Note that the question resolves negative if the telescope resumes operations but is only in reduced-gyro mode through the end of 2018.


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.

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.
