Robot performs surgery — on pig intestines

January 27, 2022

They slice. They dice. They perform complicated microsurgery without the aid of doctors…

US researchers say a robot has successfully performed keyhole surgery on pigs all on its own – without the guiding hand of a human. Furthermore, they add, the robot surgeon produced “significantly better” results than humans.

OK, that’s neat. But.

Hands up, who wants to have their intestines spliced together by the Terminator v. 1.0?

The Death Star has an inner ocean

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.

Should Pluto and Ceres be “planets”?

Demoted by the IAU in 2006, the Once and Future “9th planet”

…a study announced in December from a team of researchers in the journal Icarus now claims the IAU’s definition was based on astrology — a type of folklore, not science — and that it’s harming both scientific research and the popular understanding of the solar system.

I’m not sure I agree that moons of Jupiter and Saturn should be classified as “planets,” but frankly I see little difference between “dwarf planets” and “planets.”

Plus it wrecks the song I learned to remember the order…

World’s largest space telescope has liftoff

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! 🤞

Trace Gas Orbiter finds traces of hydrogen underground in the Valles Marineris

December 16, 2021

A.k.a., the “Great Canyon of Mars”

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…

The DART has lift-off

Technically, the two asteroids the DART is aiming at are a “binary” (they orbit each other).

The BBC’s explanation is pretty good.

They don’t even mention Bruce Willis until the final sentence.

Hang on, I think I’ve seen this before…

Oh.

Not such a great idea, then, to send them on an interstellar cruise

The spacecraft-killing anomaly over South America

October 6, 2021

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.

AstroCrete…a “blood-curdling” building technique for Mars

September 18, 2021

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…

Light from behind a black hole

July 31, 2021
MThomas

…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.
