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.
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!
Youtubersmallstarshas proposed a concept that he calls theGravity Link Starship(GLS), a variation of SpaceX’sStarshipthat will be able to provide its own artificial gravity.
Hm, I guess we’re at the point where YouTubers have better ideas than NASA…
But who pays for this? is the several billion dollar question. Not just the construction of the “hub and truss” system, but the expense of getting it into space in the first place.
Seems like science fiction at this point. But still worth a read/look:
“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.)
After completing its first year of observations in the southern sky, NASA’s Transiting Exoplanet Survey Satellite has spotted some intriguing new exoplanets only 31 light-years away from Earth.
Um. “Only” 31 light years.
One planet is 22% larger than Earth, has a surface average of around 490ÂşF, and a year of just under 4 days.
Another is more than 6 times the size of Earth, is a balmy -64ÂşF, and a year of about 56 days.
