What's next?
NASA will now analyse data gathered by the three humanoid passengers who occupied the Orion spacecraft.
Faux astronaut Moonikin* Campos, occupied the commander's seat to test the new NASA spacesuit. A pair of mockup female torsos named Helga and Zohar will report back on space risks that are unique to female bodies, which have never been near the moon.
*Moonikin is a mashup of moon and manikin.

Below, a nice picture of the capsule recovery.

Just my autistic nature, but I had severe insomnia as a result of your image, Galu.
Surely there were FIVE buoyancy balloons, not THREE? I inevitably counted them. 🙁
I have resolved the matter and can now get some sleep:
It was a trick of the camera angle. I was worried I had been transported to in alternate reality. 😆

ESA has remained tight-lipped regarding Shaun since Orion's return to Earth.
I'm beginning to think the cuddly character may have been abducted by aliens! 👽
Where’s the AI for that statement?
I can only guess 🙂
Looks like the white paint did not hold up so well on reentry 🙂
Quiet the accomplishment, but I have my reservations on why anyone would want to live in a hostile environment. All for the advance of science and mankind I guess or we’d still be living in a tepee 🙂

It does make sense. 200 years ago we could accurately calculate the positions and paths of heavenly bodies. It just took some budding scientists years. Computers do it much faster but you can go to any accuracy manually also if you are willing to spend the time.

And let's not forget that the complex calculations required to send Alan Shephard into space in 1961 and John Glenn into orbit in 1962 were performed by a team of human computers, most of whom were women who either had degrees in mathematics or were simply very good at mathematics.
Their story is told in Margot Lee Shetterly's book, Hidden Figures: The American Dream and the Untold Story of the Black Women Mathematicians Who Helped Win the Space Race, and dramatised in the film Hidden Figures.

And the Hugo & Nebula winning alternate history The Calculating Stars by Mary Robinette Kowal... based on the premise every mission must have an onboard Computer (lady astronaut). Kowal says she wrote the novel before Hidden Figures came out.
"An alternate history of spaceflight that reminds me of everything I loved about Hidden Figures" - Cady Coleman, Astronaut.
I must check it out! I see it's Kowal's first book in the Lady Astronaut series.

My current Mathematical problem is this:
Looks simple enough. Just glue things back together. But wait! Broken undetermined wires too! And a 2.2uF capacitor.
I can do this...might take my eutectic soldering iron too. 🙂

I read somewhere that you were about to embark on repairing some "Hi-Fi equipment" belonging to the neighbours, Steve.
This Sony speaker presents an electrical challenge that will certainly not require the application of Rocket Science to overcome!
It looks like there was never any absorbent material on the enclosure walls. Perhaps it's better that the sound bounces around inside!
For a similar reason, I would not bother trying to upgrade the 'crossover'. 2.2 uF capacitors must have been invented for precisely this situation! 😉

This man, Urbain Le Verrieur was a gifted calculator:
He is famous for discovering the 7th magnitude planet Neptune just by calculation of the perturbations of Uranus' orbit to within 1 degree in 1843. A telescope quickly found it.
He also calculated ananomolous precession of the perihelion of Mercory in 1859. Instead of 532' per century, it was measured nearer 574'.
This is caused in classical mechanics by the pull of other planets.
The discrepancy he guessed might be the hypothetical planet Vulcan near the sun. Turns out it is a General Relativity effect:
https://en.wikipedia.org/wiki/Tests_of_general_relativity#Perihelion_precession_of_Mercury
In Star Trek myth, Vulcan orbits Eridani 40 A.
The little blue star was the first white dwarf discovered at 16 light years.
https://en.wikipedia.org/wiki/40_Eridani
Newton's mechanics also predict a tiny deflection of light by the sun. But only half of Einstein's value of 1.75'. This is a tiny deflection. Only
about 10% of Mercury's maximum apparent size at 12' Or 12 arc seconds. Amazing accuracy and observation for the C19.

If, as Newton did, you imagine that light consists of particles which have mass then you get a deflection of light that is half of Einstein's value.
What Newton didn't know was that the 'particles' of light have an invariant mass (aka rest mass) of zero.
Just for interest, I thought I'd share examples of Murphy's Law ( Anything that can go wrong, will go wrong...) on trips to the Moon:
Apollo 7.
All the astronauts came down with a vicious Cold after 1 day. They were sneezing and snuffling throughout.
To the extent they refused to wear NASA protocol helmets on re-entry and landing. Preferring to be able to apply handkerchiefs to their snooters when sneezing.
NASA denied them the traditional medals afterwards and they never flew again. I think that was unsympathetic. 🙄
Apollo 13 hardly needs mentioning. Surely they should have skipped from 12 to 14? 😳
Apollo 15.
One of the Astronauts smuggled some postage stamps onboard, though his team-mates never grassed him up. These were later sold by a German stamp dealer for huge profits as Moon Stamps, and doubtless a cut to the Astronauts, which they doubtless planned on giving to Charity.
NASA decided it was a serious error of judgement, and the Astronauts never flew again. AW, what harm in a bit of Capitalism and Free Enterprise? 🙁
Good News tonight is I have bought a serious Telescope to observe The Moon and the rings of Saturn and the moons of Jupiter and other things for a mere £10 at the Charity Shop:
Most excellent. Fusion Science 360mm focal length, 50mm achromat objective and 20mm, 10mm and 4mm eyepieces and 45 degree prism and right-angle eyepiece tube. I leave you to the calculations.
Sadly skies obscure tonight, but I am excited to see what it can do. We are going there. 😎
Best Regards, Steve in Portsmouth, UK.

My lasting memory of Apollo 15 is when Commander David Scott dropped a hammer and falcon feather simultaneously in order to demonstrate in a vacuum that gravity accelerates all objects at the same rate regardless of their mass.
A falcon feather was carried aboard the Lunar Lander because of its call sign, which was Falcon.

A refractive astronomical telescope with 50mm aperture and 360mm focal length will give 18x magnification with the 20mm eyepiece, 36x with the 10mm and 90x with the 4mm.

Is it just me? when I look at that Apollo 15 image I see the shadow of a guy in a hat playing a saxophone !
