This is when Thanos strikes right? I'm p excited.

Good news everyone! One of Hubble's gyroscopes is back after a seven year nap.

Hopefully testing goes well and Hubble can get back to work.

We're back up as well in a mixed gyro configuration

[TsingTao]

Hell yeah!

[BerenTebogo]

There's been a lot of, I guess genuine discussion, but actually conspiracy theories, about why both Chandra and Hubble had gyro issues at the same time. Some of it is just well meaning "well I don't understand" and a lot of it is just full force fucktarded.

The reality is that they were COMPLETELY unrelated. They are both old missions. Hubbles gyros were made with the fact that they can be serviced in mind. Chandra is too far away to ever be serviceable and it is a 20 year old mission. This is the first hiccup we've had with gyros. Despite this being the first issue, we've switch to a mixed configuration and are retiring that gyro until/unless the every other gyro eventually fails. It is likely still totally fine and usable and this was just a tiny anomaly that doesn't represent a true failure, but we have more gyros and there is no reason to risk it.

[TsingTao]

Yeah, no reason not to play it safe. You want to add as many years to the mission as possible, put that gyro to sleep until you absolutely need to return it to service.

[BerenTebogo]

There is a very real possibility that in 10 years we have no x-ray telescope. Lynx is looking unlikely at this point and Athena is also pretty iffy.

You're gonna look real stupid when the aliens arrive next week.

Love me a good conspiracy theory

How long were the old gyros supposed to last for? Also what is the status on the JWST aside from it running over budget?

I don't know about JWST. SoonTM. But we cancelled our coordinated observations that were planned with them through the end of 2019.

And lifetime for Hubble's gyros is also a "I don't know" but mainly because I don't really care what is going on at Hubble unless it affects me.

Goodbye old friend.

i don't understand that. why not leave it on? it could capture some interesting shit just by happenstance.

The DSN has limited uplink resources and costs money to be run. It'd be a 100% waste of time to try to receive data from Kepler especially since it only can store so much at any given time so we'd miss most of it anyway if we just look randomly. Any time spent connecting to Kepler is time that the DSN isn't doing other things that AREN'T expected to be absolutely nothing.

Also costs time and money to have people push the data through a pipeline that transforms it into viewable/usable data especially when the expectation is that it's going to be absolutely nothing.

I remember visiting JPL last year and they were talking about the DSN and how scientists/agencies have X amount of time that is laid out to receive data. I always wondered how far in advance they had to submit their requests...

Most are standing orders. When shit goes down (i.e. Chandra and Hubble) there is always furious running around trying to get extra time on an existing comm. pass, extra comm. passes, etc. Most of the "oh shit!" telecons that I'm on always has someone running around in the background trying to get DSN to extend our 1-2 hour uplink time if they can or get us an extra comm. a few hours later. About 6 hours after Chandra when into safe mode a few weeks ago the DSN was scheduled to go down for maintenance for like 18 hours. Made everything WAY worse as we only had the 1.5 hours to get as much data as we could before the blackout.

https://eyes.nasa.gov/dsn/dsn.html If you click on Goldstone 26 (DSS-26) you'll see that we starting comms right now that has a total duration of 45 minutes. (Now being 1:54pm EST)
