Spaaaaace (Part 1)

:thinking:

  1. I don’t buy the existence of “empty space”. If there’s nothing in it, how can it have distance between things and therefore be “space”?
  2. Whose maps define “up”? :new_zealand: :australia: would suggest McArthur’s Universal Corrective Map of the World.


…not that I’m just s**t disturbing for fun, or anything… :innocent:

Caballero, A. (2022). An approximation to determine the source of the WOW! Signal. International Journal of Astrobiology, 1-8. doi:10.1017/S1473550422000015

Abstract
In this paper it is analysed which of the thousands of stars in the WOW! Signal region could have the highest chance of being the real source of the signal, providing that it came from a star system similar to ours. A total of 66 G and K-type stars are sampled, but only one of them is identified as a potential Sun-like star considering the available information in the Gaia Archive. This candidate source, which is named 2MASS 19281982-2640123, therefore becomes an ideal target to conduct observations in the search for techno-signatures. Another two candidate stars have a luminosity error interval that includes the luminosity of the Sun, and 14 candidates more are also identified as potential Sun-like stars, but the estimations on their luminosity were unknown.

Interesting, but based on more assumptions than I’m comfortable with.

An egghead at the Beijing Institute of Tracking and Telecommunications, writing in a peer-reviewed domestic journal, has advocated for Chinese military capability to take out Starlink satellites on the grounds of national security.

According to the South China Morning Post, lead author Ren Yuanzhen and colleagues advocated in Modern Defence Technology not only for China to develop anti-satellite capabilities, but also to have a surveillance system that could monitor and track all satellites in Starlink’s constellation.

The NASA InSight research mission has provided our first look at the red planet’s interior. Now, the lander is set to power down by December 2022, bringing the four-year-long scientific endeavor to a successful end.

No news here, just a lovely photo from APOD:

Please clean me…

The apollo astronauts brought small hand brushes to clean the lunar rover. Mars missions should have an articulating solar panel cleaner

Do you believe If these panel could move/tilt from time to time, the Robot could get rid of the dust? At least It could drop the dust and get some sunlight.

No. The dust clings due to static charges. It has to be physically removed. Regolith clung to the Apollo equipment for the same reason.

On Earth those guys all drove Corvettes and probably polished them every Saturday, so no surprise there…

Those pesky unbalanced electric charges!

So it’s better to invest a little more resources in research and install an efficient way to clean these panels. These probes and robots are very expensive, losing them after a while because of the Martian dust seems to be throwing money away.

Can’t we just polarize the hull plating?

Not without reversing the neutron flow and spinning the tachyons counter-clockwise. Or something.
Stale jokes aside, the biggest obstacle to anything working long-term on the Moon is probably Regolith, and on Mars it’s dust.
Proper atmospheres are nice to have.

Venus it is then… :thinking:
