Will Mars Remain an Impossible Dream?

@SallyForth Thank you, I never heard of this Movie!

Oh, it's pretty eerie. Not to mention depressing. It positively drips with... well, I can see why it resonates so deeply with a certain demographic.

I've heard it is the middle of a trilogy of films indulging in such depression, but I don't think I've ever heard of the other two.
 
Why NASA's Perseverance rover keeps taking pictures of this maze on Mars (LINK)

"The maze is a calibration target — one of 10 for Perseverance's Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals instrument, otherwise known as SHERLOC. Perseverance detects organic compounds and other minerals on Mars that could indicate signs of ancient microbial life. To do that accurately, the system must be carefully calibrated, and that's where this Sherlock Holmes–inspired tool comes in."

AI says ... "According to NASA, the SHERLOC maze is solvable."

Can NA💲A'💲 troubled Mar💲 💲ample Return mission be 💲aved?​

Can we really outspend China...so we can say "our rock collection is bigger than yours!"

"There appears to be an unofficial robotic space race underway involving the Red Planet. Both the U.S. and China are scripting strategies for bringing goodies back to Earth from Mars via their respective Mars Sample Return (MSR) endeavors."

"For America, things are currently happening in real-time on Mars. NASA's Perseverance rover is busily wheeling about within the ins and outs of Jezero Crater, biting into and snatching primo chunks of Mars for eventual pick-up by a future MSR mission. But early on, for NASA, the space agency found itself caught between a Mars rock and a budgetary and timing hard place. The space agency's plans for MSR eventually rang a price tag upwards of $11 billion. Additionally, NASA estimated that samples of Mars dirt, rock, and atmosphere wouldn't be returned to Earth until 2040."
"That plan, as blueprinted by NASA and its cooperative MSR partner, the European Space Agency (ESA), was unacceptable and declared so by NASA leadership. What followed were a set of studies for NASA, from within and outside the agency, to help pinpoint avenues to cut MSR costs and shorten the calendar time for return to Earth of prime-time Mars collectibles. Now, yet another shoe is set to drop thanks to an additional review by an independent committee looking into the MSR program."

Mars trilogy - Wikipedia

en.wikipedia.org en.wikipedia.org
The Mars trilogy is a series of science fiction novels by Kim Stanley Robinson that chronicles the settlement and terraforming of the planet Mars through the personal and detailed viewpoints of a wide variety of characters spanning 187 years, from 2026 to 2212. Ultimately more utopian than dystopian, the story focuses on egalitarian, sociological, and scientific advances made on Mars, while Earth suffers from overpopulation and ecological disaster.

These were good books. I could imagine a TV series based on them.
 
This item is dubious and critical of a project on the docket:

The TRUTH about the Moon base is now coming out, here's their disclosure plan

It seems to be about building a nuclear reactor to produce power for Moon Base use. Er, and there is a railroad involved as well. Surprise, surprise, what's given as reasons boil down to "national security."

But I'm not sure this skeptical reporting is as sane or as honest as those pushing for these things. The entire thing might also be part of an information war with China with no real substance to it. Yeah, I'm getting cynical.
 
How can we go to Mars in a single day?

Scott:
Practically, it is not currently possible for lots of reasons. But why stick to the practical? Here is a few ways we could get to Mars in a single day:

  1. Teleportation: You could beam yourself there. Light travels fast enough to cover the distance to Mars in less than one day. All you need for this to work is a functional teleportation device and accurate destination coordinates (so you don’t end up in empty space where Mars was previously when you pressed the “go” button). Make sure you pack a teleportation device with you though. If you don’t, you will end up stuck on Mars with no way to beam yourself back.
  2. Warp Drive: It works in Star Trek, so it must be possible, right?? I think the best way to design this is an engine that curves spacetime tightly in front of the direction you want to move and expands it behind you. This allows you to ride like a surfer through the spacetime continuum. The best part is that you don’t actually move much, per se. The spacetime moves around you. This enables you “travel” much faster than the speed of light without the acceleration effects crushing you into goo. There are minor considerations like how to avoid the compressed spacetime from ripping you and your ship apart into its component elementary particles and energy and the necessary physical theory that would permit such technology from being developed, but otherwise, it should be straightforward.
  3. IID: The Infinite Improbability Drive works by calculating all of the probabilities that you find yourself at any given point in the universe and then specifying a particular improbability to become actualized. I have no idea how this would ever be possible, but Douglas Adams says it is in the Hitchhiker’s Guide to the Galaxy so I am going to assume it is.
  4. Star Gate: This one requires you to tow a portal or gate out to another location such as the surface of Mars. The other side of the gate is here. Because the two are somehow entangled, you just activate it and then you can step through. Wear warm cloths and a pressure suit. The physics are a little hazy but I did see it done in a movie and read about it in “Ring” and other books by Stephen Baxter.
Those are few way I can think of off the top of my head.
