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.

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!

“What is the evidence against the possibility of life on Mars?” Levin wrote. “The astonishing fact is that there is none.”
Uh, no, sorry. That’s an illogical fallacy called “begging the question.”
Often phrased like this: “Absence of evidence is not evidence of absence.”
Or, as a friend once joked, “Just because you haven’t found any aliens doesn’t mean there aren’t any!”
Well, yeah, but that doesn’t prove anything except that we just don’t know.
See, science doesn’t work like that. It demands skepticism, careful theorizing based on positive evidence.
And replication.
If findings can’t be independently confirmed and reproduced by an outside observer, then the evidence isn’t strong enough.
Sorry. No smoking gun. Yet.
(Believe me, if scientists knew that Mars had life, we’d hear about it ad infinitum. Carl Sagan put it best: Scientists are terrible at keeping secrets.)

“Once you’ve exploited the solar system, there’s nowhere left to go.”
Frankly, the idea that we puny humans could ever even begin to damage the solar system is laughable.
What would be more worrisome is who – or what – would be doing the work. Why hire people if you could make robots to do the work for you?

In February of 2017, a team of European astronomers announced the discovery
of a seven-planet system orbiting the nearby star TRAPPIST-1. Aside from
the fact that all seven planets were rocky, there was the added bonus of
three of them orbiting within TRAPPIST-1’s habitable zone. Since that time,
multiple studies have been conducted to determine whether or not any of
these planets could be habitable.
What’s up with the boring names?
I propose we call them Liesl, Friedrich, Louisa, Kurt, Brigitta, Marta, and Gretl. The most habitable is Kurt, because he’s so magnetic.
But the star, of course, is Maria.
Buh-DUM-dum.

As a kid I remember reading about “Vulcan,” which people used to think existed between Mercury and the Sun but always orbited on the opposite side.
Completely fictional, of course.
But…
Vulcan made a comeback as the fictional home of Spock in Star Trek. It was said by Star Trek creator Gene Roddenberry to be orbiting around 40 Eridani (also called HD 26965), a triple star system in the constellation of Eridanus “the river” in the southern hemisphere just 16 light years distant. In September 2018, astronomers at the University of Florida in Gainesville found a “super-Earth” exoplanet orbiting exactly where Vulcan was said to be.
There is only one logical conclusion…

The three choices fit IAU naming regulations and are associated with mythological creatures and figures that reflect aspects of 2007 OR10’s physical properties, which include rock, water ice, possibly methane ice, and a surface that’s red in color.
Your three choices?
Gonggong (共工, the bringer of floods 洪 and chaos)
Holle (which I always thought was Hulda or Holda)
Vili (which I knew as Wela in English class)
At least these scientists learned an important lesson from our recent past…
