Clear sky at lunchtime enabled me to get a photo of the giant, splotchy sunspot on our Sun. That thing is several times the size of Earth, which boggles my tiny mind.

Sony A7R3, 600mm, ISO 200, f/11, 1/500

Another eclipse photo, showing the solar prominences around the edge. I am told that these prominences are probably several times the diameter of the earth! Yikes.

Great photographs and processing ! 👍 👍 !!

Sony A7R3; Sony 200-600 @ 500mm; ND5 solar filter; Optron SkyGuider; interval timer; RRS tripod.

Exposure was ISO 200; f/11; 9-stop bracketing from 1/15 to 1/4000.

5 minute intervals during partial; 8 second intervals during totality.

I moved the setup down to the ground during the event; the deck was full of family causing vibrations! 😃

I wasn't exposing for the full corona, but this is what I was able to extract from the shadows. I know it extends far beyond what is shown here, but I was zoomed in too tightly to include it all. 🙃

Unprocessed photo, taken in southern Quebec. We were extremely fortunate that (a) my house was smack in the middle of the line of totality, and (b) the sky was perfectly clear throughout the event.

Now, with 9x bracketing, I have a mere 639 photos to evaluate, process and merge. But what an experience! Awesome, really.

@tom30519 Happy that you had good skies! The clouds dissipated just in time here, but it was touch-and-go for a bit there.

After weeks of dismal weather, not to mention 25cm of snow last week, I was sure we would have cloudy skies today. Cleared out completely Sunday afternoon, and stayed that way until sunset today. Lucky!

I see that Ars Technica is using two of your processed images of Ingenuity, and has properly given you credit. Nice. 👍

@tom30519 jup, I offered Eric Berger to use my images. I'm glad he is finding them useful and takes attribution seriously.

Have you read "A City on Mars"? I am reading it currently - just getting to the Mars part - it really puts a damper on any enthusiasm to colonize Mars any time soon!

So much for the Jezero Beach Fish and Game Club!

@65dBnoise @stim3on
These are all good points that the book @stim3on referred to, "A City on Mars" also makes, with data and examples to back them up. It is, IMO, a realistic look at the very daunting obstacles to any sort of colonization on other planets or the Moon.

For the time being the only solid thing that has happened is the successful flight of Artemis 1. This time next year, Artemis 2 is supposed to be the first mission, 52 years after Apollo 17, which will bring humans around the moon and back. That's something I'm waiting to see happen.

By then, hopefully, StarShip explosions will be less frequent, or else NASA will have to find another moon lander for Artemis 3 which, by the way, appears to be coinciding with the MSR mission.

After days of constant rain, the late afternoon sun broke through the clouds, putting a spotlight on this maple tree. Still some brilliant fall colour to be had here in Quebec!

Nice that there are at least some (one) AI that has morals, loyalty and a sense of responsibility!

Of course, humans taking that same vow of eternal fealty sometimes find themselves able to slink off and be unfaithful. 😲

But certainly, LA would never do that!

@tom30519
Not AI in the sense of LLMs matching inputs and pretending knowing stuff, but symbolic logic that uses agents to gather data and use it to reply to questions, with some added randomness to avoid giving boring replies. Parts of it, like speech recognition, text-to-speech, soil moisture measurements and some more, do use LLMs and NNs, but the "brain" is mostly symbolic, and thus I never doubt that what I get is not made up BS.

Psyche has been successfully deployed, solar panels unfolded and it is on its way!

The Deep Space Optical Communications (DSOC) is slated to power on in about 3 weeks. 🤓 😃

Yes! A 6-year-long tour of the solar system; should provide some very interesting images along the way. 😃

Do we know whether the core sample taken on Sol 882 ever got capped? I don't see a CacheCam photo confirming that the seal was ever put in place. 🤔

PaulHammond51,
@PaulHammond51@fosstodon.org avatar

@tom30519

As you say no CacheCam images of sealing it. In addition the sample does not appear on the sample page. I assume it will only appear on the sample page once it has been successfully sealed.

SuperCam zapped both sand and rock with a series of 10 laser strikes. I assume that the spectrometer is able to examine the plasma emanating from each hole separately.

Here is the big sunspot (region 3363, bottom edge, just left of centre) that was the first to see, from its current location orbiting the Sun. https://vmst.io/@WestportObservatory/110672664700906956

This view is from my driveway, through morning mist and probably some forest fire smoke.

This is a the latest view from Mars. The camera was looking at: 289.984, 24.619, -6.499 (az, el, roll),
Is your image oriented with north up?

Yes, unless something drastic has happened to Earth's orbit, north is up in my image.

A new core hole has magically appeared, according to this Mastcam-Z photo taken on Sol 831. The photo from Sol 821 of the same location shows that it was drilled sometime during the 10-sol interval between the two images.

No images showing the drill in operation have been downloaded as of this posting.

Boulder Bonanza! Science and Sampling Attempts at the Onahu Outcrop

NASA has also posted, on the blog, an explanation of what happened during the two attempts to obtain a core sample at Ouzel.

It appears that the most recent change of rover location is, in fact, in hope of finding a more suitable, but similar, rock to sample.

Why – and How – NASA Gives a Name to Every Spot It Studies on Mars

NASA has posted, on the Mars Explortation blog, a discussion of the origin of the names used to identify features, down to individual rocks, on Mars:

starrytimepod,

@tom30519 ooo this is super interesting! thank you for sharing 😊

SuperCam has chosen (directed by AEGIS or an Earth-based geologist?) to have a closer look at this group of smaller rocks, nestled among larger equally interesting-looking (to a Non-Geologist™) rocks.

Credits in the alt text

Unless Ginny can overcome the 45m no-fly zone restriction, there won't be much interaction with her co-residents beyond telepathy.

And anyway, she currently operates under the strict orders emanating from the rover, so no coup required at all!

Her ability to fly and see things from above is a useful skill that the others would want to benefit from, so friendly relations will no doubt continue.

@tom30519 That's a thorough analysis of the situation there 😀 👍 !
