Boldly going where we already went fifty years ago

Have some Proxima Centauri with ESPRESSO
January 20, 2020
“Proxima is our closest neighbor in an immense universe. How could we not be charmed by it?”
Well, the planet may or may not exist (the confirmation data won’t be publicly available for another couple years).
And it is most likely not inhabitable — despite being dubbed a “Super-Earth” (which really only refers to size and not whether it’s “Earth-like” or not).
Still, regardless of these facts, the most important part of this article in Scientific American is the science:
“We tried different tools to prove ourselves wrong, but we failed. However, we have to keep the doors open to all possible doubt and skepticism.”
Yes, the astronomers tried to prove their own discovery was a mistake. That’s how it works, folks. Challenge your assumptions, not jump to conclusions. Continue Reading
New “habitable” Earth? 🌍
January 10, 2020
The newly discovered exoplanet, called TOI 700 d, is located about 100 light-years away from us and is roughly 20% larger than Earth.
Okay, not exactly close, but looking good…
A year on TOI 700 d takes 37 days.
Um. Wait. What?
One thing astronomers have discovered though is that TOI 700 d is tidally locked to its star, which means that one half bathes in eternal sunlight, and the other half always exists in darkness.
Oy.
And even better…
One of the burning questions is whether the planet has an atmosphere or not.
Is this really the best way to phrase this? 😂
I vote we pass on this one…
PS I’ve been trying futilely to get WordPress not to screw up the formatting. To no avail.
Khufu, I mean, Cheops is a go!

Ever wonder this about “Super Earths”?
Do they have atmospheres and how thick are they? What kind of clouds? Do they possess oceans on their surface? Do they have rings and moons? Cheops ought to be able to address such questions just from looking for these tiny dips in light during a transit.
ESA finally does something! Wow. Go Europe!
I love how BBC says “The Americans” when referring to NASA, as if a) American is an ethnic group and b) all NASA scientists are American.
But anyway…
Prof Didier Queloz, who won this year’s Physics Nobel for discovering the first planet orbiting a Sun-like star in 1995, was on hand to watch the launch.
You can watch/listen to his interview here.
ESA and NASA? Airbus? Still not ready? 🤦♂️

Right now, engineers have got a dummy rover practising the business of retrieving packaged rock samples. And, yes, the stand-ins really are whiteboard markers.
Yay! Whiteboard markers. Um. OK.
But different agencies and companies are finally working together?
Great!
Wait. What’s the catch?
It is, though, going to take more than a decade to achieve.
Sigh.
It’s life, Jim, but not as we know it. Maybe.

The pattern remains a mystery, but researchers are beginning to narrow the possibilities.
While the changes are most likely…geological in nature, planetary scientists can’t completely rule out an explanation involving microbial life.
Just as the Viking landers claimed? Uh-oh.
Or is it just chemicals (perchlorate, bleach-like substances) in the soil, releasing oxygen and methane depending on the amount of sunlight/heat?
How would this affect humans who set up camps in the low-elevations areas, where they could be closer to water?
Hm…
The exciting world of regolith oxygen extraction
October 25, 2019
Future moon settlers might benefit from oxygen extraction from lunar regolith as it can be used to create breathable air as well as a source for fuel. In addition, the newly found extraction method might also be useful for Mars colonization.
Regolith covers the Moon and Mars (and presumably many other potentially habitable rocky bodies).
Of course, the composition of regolith on the Moon differs from that of Mars.
But if the new method can extract sufficient quantities of both oxygen and hydrogen, there should be ample amounts for both human usage and rocket fuel.
(Yawn.) “Dry” science? Sure. But think of the (fictional) possibilities!
