Not a bad idea. Got any other Artemis conspiracy theories? 😂

was hoping others might chip in tbh. We're bound to be able to think up some more once it gets to the moon 😉 

[DaveL59]

oh dear, this don't sound good for future launches

 

might solve the starlink issue for our imaging friends tho 😉

What moon? You mean that hologram in the sky?   The one that comes up every night and glitches sometimes so that it comes up in the day?

we're all living on a huge stage set I tell you, all roads lead back to here. Truman show on a large scale 😉

That's a good one for the flat-earthers! 😂😂

"All roads lead to Rome". They weren't wrong. Just walk for long enough, starting from Rome, and you'll get back to the same spot.

hehe yeah, I think a lot of the problem is no WDR, or at least it can't handle the very bright close surface so it's washing out. Lower shutter/exposure but enough to grab Terra in the background wouldn't be long enough to show any stars etc. Getting stars of course, longer exposure, total burn out of the ship in the image and likely flare across a big chunk of the pic too.

Smartphone cameras have built in HDR modes.  You'd think they'd have it in "space" cameras by now.  It's not rocket science (it's imaging science) to quickly take multiple images at multiple exposure levels and then use a bit of processing software to quickly combine them into an HDR image.

some IBM thing up in Scotland that we remotely accessed

I was on one of the last IBM mainframe CPU design teams in Poughkeepsie, NY, that worked in ECL logic in the late 80s/early 90s.  That was some fun stuff to design in compared to CMOS.  15-way OR dotting combined with 8-way AND blocks allowed for very shallow but very wide decoder/selector circuits.  Also, emitter-follower drive capabilities allowed for enormous fanout, negating the need for buffers.  Switching to CMOS was a shock as it required relearning gate-level circuit design.  You couldn't get nearly as much logic done in a single clock cycle, so you had to increase your logic's pipeline depth quite a bit leading to increased latency.  You also had to add a lot of buffering due to terrible on-chip CMOS gate drive capabilities, further increasing pipeline depth.  It took about a decade for IBM flagship CMOS mainframes to surpass their bipolar counterparts in sheer performance.  Of course, they also shrank from ~12 enclosures to 1, with a commensurate drop in power consumption and cooling needs.

Ooh, that's nice...does the Earth look a bit distorted to anyone else?

It’s not distorted! Everyone knows it is flat! 
The reason things seem round is because of the camera lense. 
If they made oblong camera lenses then all would appear correct and we could all throw away our coma correctors.

Incredible.  I recognise and understand every individual word but have no idea what you are talking about lol.

Waaaaay too advanced for my crease-less brain.

Artemis never happened. They obviously recycled the Apollo footage, which was also fake by the way 🤣

Wow. Now *that* is a job I would have loved. Very jealous. I've worked in IT all of my life but have always felt that I missed some of the most interesting eras of computing.

I expect tho that part of the problem in a scene as that one is that the close extra bright body of the ship is too extreme in the range for them to handle so be able to also pick out the marble. Same for the stars as the marble is too bright. Anything's possible tho but depends how much they could spend on the sensor and processor tech and fit the image into a small data stream. Not too bad an image tho given its limitations, hopefully they'll get better as the mission progresses.

tho that first pic looks like a model offset from an old mouse mat 😉

Of course. That was why they spent so much effort remastering the Apollo pics ... they knew that 21st century conspiracy theorists would expect much more detail than their 1960s forebears.

They didn't do a very good job - the rockets don't even look the same!

The old ones sure looked more polished didn't they?

These new ones look like they're covered in rust, screams of kwaliti innit 😉

Looks like one of my old mouse mats from 20 years back. That was grey and fabric covered, looked just like that after lots of use as it started to wear. Someone must've been dumpster diving and saved it just for a staged pic 😉

tis patina innit, from the decades of storage of that big unpainted metal cylinder. Guess they're following the USA trend for Rat Rods

[DaveL59]

hmmm will there be another SLS launch...

 

 

[Ags]

The SLS is like any other vehicle: the moment you drive it off the lot it loses half its value!

[DaveL59]

sounds like there's a few glitches tho, some RAM ECC events relating to the star trackers and something else being open uncommanded. Missed the start of their briefing.

See the First Stunning Photos of the Earth and Moon From Artemis 1!

Odd title, considering that I can see more of the Earth with my own eyes and more of the moon through my 2 inch telescope 🤣

Now this is a much better image ^^^^^

And Artemis 2 is TENTATIVELY scheduled for 2024. I'm just not sure if we could stand the suspense again--perhaps we will have so, Artemis 2 flight AKA Should Launch Someday, date pending.
