Science fiction, actual science, history, and personal ranting about life, the universe, and everything

Still, they persevered!

Great job, NASA! Landing on Mars is always a tricky business.

Now all Perseverance has to do is find traces of life, save it without contamination, and then wait for another rocket, another rover, and a satellite to get in orbit so the samples can be sent back to Earth.

Piece of cake, right?

Sorry, there’s no “Planet X”

This doesn’t exist, but it’s a cool drawing.

Critics of the Planet Nine claim said the apparent clustering of the discovered TNOs might only be because that’s where telescopes were looking or were most sensitive.

If you are looking to find evidence to prove your theory, it’s much easier to find what you’re looking for.

You should instead try to find evidence to disprove your theory, and then ask at least two more people you don’t know (or even better, generally disagree with) to try to find evidence to support your theory.

“Seek and ye shall find” is a terrible way to support a claim. Have the courage to challenge your beliefs.

Also, it’s Planet X, not 9. Pluto is a planet. So there, Neil deGrasse Tyson. :-p

Maybe there is Hope, after all

Congratulations, UAE! The Hope Probe (al-Amal) successfully entered Mars orbit on February 9th.

Made in the US (Boulder, Colorado) and the United Arab Emirates (Dubai) and launched from Japan, it shows what hat can be accomplished through international cooperation instead of competition.

Maybe it is truly Hope, after all, and not just for Arab states.

Sorry, Venus is just a lot of gas

There’s a reason I didn’t post a while ago about the supposed “there’s life in the clouds of Venus” finding.

It was just a big load of gas.

Sorry, folks. Venus is a big rotten egg. 🥚

Magnetic reconnection plasma thruster: Not too fast, not too slow, juuuust right

February 4, 2021
MThomas

A crewed mission to Mars may be more practical thanks to a new rocket concept developed by Fatima Ebrahimi, a physicist at the US Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), that uses magnetic fields to generate thrust.

Looks good so far…

…although it’s just a computer simulation right now and the magnetic thruster model hasn’t even been built yet.

Ah, well, just repurpose an existing ion thruster, right?

Hmm. I’m not a rocket scientist, but.. 🚀

All-civilian space flight? Uh. Don’t sign me up.

The CEO of an online payment company is the perfect leader for an emergency in outer space.

OK, hands up who thinks this is a really super dumb and risky idea but isn’t terribly surprised by the super dumb and risky things Musk continually blurts out? 🤷‍♂️

35 Years Ago: Remembering the Challenger

January 28, 2021
MThomas

It’s hard to believe that it’s been 35 years since the disaster that claimed the lives of all seven Space Shuttle Challenger crew members.

I remember it well. Being sent home early without being told. Watching the TV news at home in silent shock with my parents and younger siblings, tears streaming down our faces.

President Reagan’s speech at Congress, made in the place of the traditional State of the Union address, ended with “they slipped the surly bonds of Earth…and touched the face of God.” Probably the finest and most decent thing he ever did (even my parents, who voted for Jimmy Carter and Walter Mondale and intensely disliked Reagan and everything he stood for, couldn’t help but be moved by his words that day).

Thoughtless jokes circulated our school the next week or two. (“What’s the last thing Christa MacAuliffe said to her husband? “You feed the dog; I’ll feed the fish.”)

Even today, we focus on the school teacher who died and almost ignore the rest of the crew. Something like three dozen schools now bear her name. But NASA engineers have never forgotten. They just find it so difficult, so painful to write and talk about their friends and colleagues who perished.

There was a morbid fascination with the way in which the Challenger crew met their fate. My friends came up with all sorts of gruesome stories they claimed to have “heard,” mostly about body parts washing up on beaches around the Caribbean.

The fact is, we were traumatized. Kids do all sorts of insane things to hide their fears, insecurity, and general inability to answer the question what am I supposed to feel/do/say about this?

Challenger marked a turning point in the US space program. It set NASA back in many ways but also provided great insight into what needed to be fixed, what needed to be done to push forward our knowledge of space and the great beyond.

There is/was no going back. Humanity is a space-faring race and must continue to strive to reach beyond its grasp…”Or what’s a heaven for?”

Remember, honor.

Emulate.

Onward and upward.

The One Small Step Act: Only for US?

January 16, 2021
MThomas

It’s a small step. It applies only to companies that are working with NASA; it pertains only to U.S. lunar landing sites; it implements outdated and untested recommendations to protect historic lunar sites implemented by NASA in 2011. However, it offers significant breakthroughs. It is the first legislation from any nation to recognize an off-Earth site as having “outstanding universal value” to humanity, language taken from the unanimously ratified World Heritage Convention.

https://astronomy.com/news/2021/01/neil-armstrongs-bootprint-and-other-lunar-artifacts-are-now-protected-by-us-law

The author believes this shows that “nonpartisan” desire to journey to space and preserve human heritage.

Hmm.

Well, I do agree with the assessment that it’s only a matter of time before the Moon is occupied by multiple political entities (China, India, Russia, the US, ESA…) and probably even a few private enterprises as well. Will the private company-sponsored missions agree to abide by a US law?

We’ll see.

Tardigrads…In…Space…I mean, On the Moon…

December 28, 2020
MThomas

Despite the impact, scientists believe that if anything survived the crash intact, it may well have been the tardigrades. The microscopic creatures were sandwiched between micron-thin sheets of nickel and suspended in epoxy, a resin-like preservative that acts like a jelly — potentially enough to cushion their landing.

I, for one, look forward to our lovably cute waterbear overlords…
