New analysis of one of Saturn’s moons suggests that it may harbor a liquid ocean. No, not the usual suspects – the new culprit is Mimas, the little moon with a big crater, which gives it more than a passing resemblance to the ‘Death Star’ from Star Wars.

Add Mimas to Europa and Enceladus as possible moons harboring ET.

The James Webb Space Telescope – Hubble’s successor – has successfully lifted off.
Now starts the “two weeks of terror” as it gets into position and unfolds. Fingers crossed! 🤞

The original article title?
“Astronomers Detect Secret Water Reserves in The Largest Canyon in The Solar System”
Science isn’t quite as catchy. The hydrogen may indicate water in the form of permafrost 3 feet and more under the surface.
The high-hydrogen region is about the size of the Netherlands, and overlaps with Candor Chasma, one of the largest canyons in the Valles Marineris system.
Looks like there may be some competition for who gets to land near here first…

Hang on, I think I’ve seen this before…
Oh.
Not such a great idea, then, to send them on an interstellar cruise…

Over the years, the SAA has been responsible for several spacecraft failures and even dictates when astronauts can and can’t perform spacewalks. As the space around Earth becomes filled with an increasing number of craft, what does the SAA mean for the future of spaceflight?

This post is from back in February 2021, but I just stumbled across it this morning and thought it was an interesting read.

This part caught my eye…
Radiation is a colorless, tasteless, and odorless enemy…
…and I couldn’t help thinking…
Iocaine powder?!?
It’s okay. I’m immune 😂
Anyway, the article linked above is food for thought. Whenever electronic objects pass through the SAA, which is where the loops of the Van Allen Belt dip perilously close to the Earth, the electronics get a massive amount of radiation and go haywire.
Seriously expensive to shield stuff up there — and as more and more satellites (and people) go up, so does the risk.

The blood, sweat, and tears of pioneering astronauts could literally turn Mars regolith into building materials.
First, however, they’d need to get the 3D printers there…

…while light cannot escape a black hole, its extreme gravity warps space around it, which allows light to “echo,” bending around the back of the object. Thanks to this strange phenomenon, astronomers have, for the first time, observed the light from behind a black hole.

Einstein has been proven right. Again.

Well, OK, technically it’s the mantle, not the crust.
But it is thick. Super thick. And no gradations like the Earth.
Extrapolating to the known surface geology of the rest of the planet, this suggests an average thickness of between 24km and 72km. By contrast, Earth’s average crustal thickness is 15-20km.

So what does this mean?
For one thing, it probably explains why there’s no breathable atmosphere on Mars.
Mars never developed a global magnetic field to block solar radiation. So it’s atmosphere was basically ripped right off.
And any terraforming attempts in the future would fail on a global scale. But maybe locally it might work…

Like other nations, China “regards Mars exploration as the preferred destination for deep space exploration,” Wang said.
https://abcnews.go.com/amp/Technology/china-unveils-ambitious-roadmap-human-mars-exploration/
China’s plan calls for setting up a permanently occupied base and a fleet of interplanetary craft. Probably it’s a good idea to first see whether it can meet its goal of landing people on Mars in 2033.
Of course, China is “willing to join hands with our counterparts and partners all over the world,” but it’s unlikely NASA, JAXA, ESA, and the UAE and other countries not named Russia will “cooperate.”
The next space race is here. Just wait until multinats actually decide asteroid mining is worth the risk and expense.

The inclusion of an ion propulsion system in a long-running, Earth-orbiting space station will give researchers a chance to test out the tech while astronauts are still close to home — and if it works as hoped, it could one day ferry explorers to Mars and even more distant destinations.
https://www.freethink.com/articles/ion-propulsion
That’s a big “if.”
Another is what the price will be, since no doubt this neat new tech won’t easily be shared among nation-states.
Just yesterday Chinese astronauts entered their new space station for the first time. They weren’t allowed into the ISS. Now they don’t need the ISS.
The old rivalries will follow humanity into space…but for how long will the rivalries remain…
