Updates on Euclid: It was lost...

Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! The European Space Agency's Euclid Mission has just finished commissioning but it didn't all too smoothly, let's talk about why!

Cheers for the update. You have taken a complex topic and repackaged it, into something easy to digest and understand 👍👍👍

[miket-jj]

We know the risks and we take them because we care. And if things go wrong we learn. This isnt a baking competition. Good luck to all on this one. Looking forward.🙂

Euclid is so cool.. im sure these mega geniuses will make a workaround for the stray light problem. thanks for keeping us up to date ❤

[johnlewis]

With such massively complex instruments things are bound to go awry. It’s got to be almost impossible to foresee every eventuality, great vid!

[theemissary]

Nice video and all, but my heart dropped when I read the comment "It was lost..." Glad it's still there and working.

[DavidBrant]

Fingers crossed for a bright (but not over-exposed) future. Bring on the space data! 🙌🏼 ❤🎉

[RalfTenbrink]

Great video. Very interesting to hear about all those issues.

So glad Euclid made it through and turned things around, can you imagine the disappointment if we had not had her sending back these beautiful data gifts. Thanks as always #1 @SpaceMog . Your vigour and message encourage me to continue. 💝💖💗💓

So beautiful that I can't concentrate

Poor Euclid...Maybe with patience we'll find out that the way it is was actually useful for something else

[BZAKether]

I guess that for great and ambitious missions things tend to go wrong all the time. I remember the many Space Shuttles missions that were needed to get the Hubble Space Telescope working (Some say that it would have been cheaper to make another telescope), and James Webb got so many delays that I wondered if it was going to be launched at all. But in the end, everything was worth it.

[AndersWelander]

We must have a telepathic connection because I have been thinking for a few days now that I wanted an update about Euclid. :-)
So if they have officially finished commissioning then I assume they fixed those issues.

Sounds like there are lots of lessons here for the next team to build observatories to be deployed in space. Expensive lessons, but still.

Thanks for the great content! You always explain things really well!

EDIT: A question popped into my mind just after writing the above: Has there ever been a suggestion to use the Sun-Venus or Sun-Mars L2 points, or even other L points, for observatories? It just occured to me that Sun-Earth L2 observatories are great in their way, but being stuck there limits where an observatory can point (depending on the design, they might not even be able to point away from the sun). By spreading similar observatories out to a couple of different places around the solar system, one could effectively always have something that can quickly be redirected to a place where something unforeseen is happening. I suppose the counter-argument is that then one might just as well spread observatories out in solar orbit without regard for L points.

The Earth has in itself to be the perfect planet I say.

I know EXACTLY where Euclid is at all times. You can find it at 41.5931° N, 81.5268° W 😜

SolarEnenrgy: enigmatic or problematix, the joys of excitement... and, space rocks💚❣{\} ;x

[thomasseiler]

Again and again this Finagles or Murphy's law is so pitiless. But not seldom, there is someone who can fix it. Hope dies last. Wish you all a good time.Dankeschön

[EscapeRealityMedia]

Poor telescope it had a very hard life 😢
don’t worry though it’ll become a happy telescope soon like all of us it just needs some time to figure things out

[flatisland]

..or as Manfred Mann would say: Blinded by the Light

[stevenyee]

The animation shows Euclid panning up and down during the survey. I would think the spacecraft is mostly stationary and take surveys as the sky appears in front of it?😳
