to preserve the precious fuel.

Thanks for clarifying that, as for the fuel, well someone is going to have to take a pod or something out there with a fresh gas can!

Tower successfully extended 😀

Great news!

Doubtless one of many... but with graphics of the various deployments:

Hopefully this doesn't happen! 🙄

Some great info in this video.

I grabbed 5 x 300s exposure last night and crated a GIF.  Conditions appalling but scope aimed at where the Ephemeris said and the only thing moving is highlighted.

I can't get the animated GIF to work on any website other than opening it on my computer

Might on Twitter?

[NenoVento]

Maybe convert it to video and upload it to youtube?

Literally cannot wait to see this picture if it ever gets made. This seems like a very "real" object to image, not that the ultra deep fields are not real, but M82 is a target most are very familiar with so very excited to see JWSTs take on it!

Reaction to first image, when we get it.

I made a video of it in DaVinci Resolve from the five still subs.  See if this works on whatever Fourm software SGL is using.  Conditions were dreadful but we had about 30 mins of semi clear sky.

Just left of centre and slightly above the centre line.

I see it!  Thanks for all the effort!

Nice one @kirkster501. Took me a while but found it eventually. Good going given how dim it looks 👍.

I've just seen a bit on the beeb about unfolding the solar shield.  A big object made of 5 thin sheets of 'foil' which sounds somewhat delicate.  The first thing I wondered about was how such an object is protected from 'impacts' from meteors etc. ?

You just run the Ephemeris tool to get the JWST coordinates for your location and then enter them into Stellarium.

I keep trying this and Stellarium crashes everytime, there is even a report about it at https://gitmemory.cn/repo/Stellarium/stellarium/activity?page=7

What am I doing wrong? 🤔 

Using TLE's from https://celestrak.com/NORAD/elements/tle-new.txt

I wondered the same regarding micro meteorites and stuff, maybe they’re very sparse way out there away from earth where there’s debris speckled around earth from countless launches and stuff. One would think that sun shield would look like a spaghetti strainer after a few years.

There's a bit of info here re meteoroid damage to the sun-shield.  https://jwst.nasa.gov/content/observatory/sunshield.html

Interesting, thank you!  They obviously didn't watch 'Gravity'!

Webb Seperation from Ariane 5

This real-time video shows the separation of the James Webb Space Telescope from the Ariane 5 launch vehicle and the subsequent solar array deployment.

This video shows the view from Ariane 5’s upper stage, taken by a camera manufactured by Irish company Réaltra Space Systems Engineering.

Over about the next two weeks, NASA will provide broadcast coverage, a media briefing, and other updates on major deployment milestones for the James Webb Space Telescope, the world’s largest and most powerful space science telescope.

Broadcasts of milestone events will air live on NASA TV, the NASA app, and the agency’s website.

This might have been asked before, but according to the latest tracking, the JWT is nearly half way, day 5? So are we to expect it to slow down? I have noticed it’s has slowed a little. But it’s another three weeks plus, I haven’t come across the explanation for this but some one on here might have, if you have can you drop a link for me…mia.

[Ouroboros]

It certainly has slowed hasn’t it? A few days ago I recall it doing 5 miles/second. It’s under half a mile per second now.

As long as it doesn't go negative...
