Space and stuff

Very good episode of Sky At Night: Exploring Jupiter. Ganymede, one of the moons, is the largest moon in the solar system, even larger than Mercury and is thought to have a liquid water ocean below the icy crust. ESA are sending a JUICE probe there, that will eventually go into orbit around it.

Also, found this easy-to-read article about matter. However, there is a theory that matter repels anti-matter.

Bananas!😂

“The force of this matter-antimatter repulsion could explain why the Universe is expanding at an accelerating rate, eliminating the need for dark energy and possibly dark matter.”

Gammerz The thing with a lot of physics is there are issues with mathematical symmetry in the equations - for example that x squared and (minus x) squared both equal the same thing. So a lot of physics equations work in two directions and physicists kind of have to look at the universe and decide which way it goes. And they don’t always get it right first time.

So perfect clear skies as it was getting dark and I decide to get the scope outside on its go-to mount and also setup the equatorial mount for the camera to do wide shots for the meteor shower. While it’s still getting dark enough I spot Jupiter not too far above the horizon and set the scope to it. Fantastic view although small and I could see all the moons.
Not far along from Jupiter was Saturn, so target that on the software and the scope lines up and there it is, rings and all in my eye-piece, first time I’ve seen it properly like that!!!
Start setting up the camera for some meteors and 10 minutes later it gets windy, cloud completely covers the sky and it starts to rain 😭😭🤬🤬
One wee bonus though as I was setting up the scope I was sure I could hear someone walking up my drive but couldn’t see anything, turn my red headlamp on and about 5 feet from me is a Badger!! he soon scarpered off, must have been looking for the blue light district

This should happen (wether and safety checks allowing obviously) tonight.

As much as I love the BE-3 engine you have to wonder about how Mr Bezos is feeling. 😀

Well there’s a surprise. I wonder what the common element between Amazon and the Space Penis is? Could it be Mr Space Penis?

Note to BO: if your going to try and claim that it’s all nonsense don’t create and advertise the new position of diversity and exclusion officer 14 hours before a fairly web published and damaging essay into your corporate culture is published.

Pirates didn’t get it - oddly that was a serious concern.

Why the human race continues to promote sociopaths to the highest levels of power I’ll never understand.

Brave can’t properly credit the origin of this but …

why are space wars always depicted with laser weapons, when in reality a single stone thrown at high speed can damage a lot of things? not just a single stone….
once upon a time…
a small scout ship was being pursued by a larger attacker. the scout electronics were better, and the ecm prevented the corvette from hitting it with lasers or missile fire. on the other hand, the scout didn’t have a beam weapon got enough to do more that scorch the paint of the warship
in desperation, the scout pilot dismounted the furniture from his salon, and everything else that wasn’t bolted down and was not critical to the operation of his ship. all this debris was loaded into the cargo airlock.
he carefully computed his orbit around the world he’d been exploring, the path of the corvette, likely course changes, etc…and at the right instant jettisoned the bric a brac.
two orbital passes later, the cloud of debris blindsided the corvette at 6 km/s….
the couch from the salon, a nice comfy thing that could recline into a bed, tore through the engineering section of the hunter…..
upon returning to base, during debriefing, there was skepticism that a sleeper couch could kill a warship
the scout rewrote his report, indicating that he’d destroyed the enemy with…a futon torpedo.

Sorry 🤭

Brave it’s crazy. This was literally the plot of the first five minutes of the film ‘Gravity’, and that ended with effectively the destruction of everything that lives in low earth orbit. I genuinely don’t know what the hell they were thinking.

Gammerz

With GPS guided weapons needing satellites plus the intel they can supply, achieving “space supremacy” will move the battlefield into space. It’s a just matter of time.

Is there a groan emoji?
