Japan lands on the Moon — for just a few hours

January 20, 2024

A Japanese robot has successfully touched down on the Moon but problems with its solar power system mean the mission may live for just a few hours.

The Smart Lander for Investigating Moon (Slim) put itself gently on the lunar surface near an equatorial crater.

Or SLIM, if you want to actually write acronyms properly (snark).

Also, it’s JAXA, not Jaxa. And NASA and ESA, not Nasa and Esa. But I digress.

Anyways, kudos but too bad yet another space mission failed. At this point I’m wondering how on Earth NASA managed to land people on the Moon so successfully in the 1960s and 1970s without killing half of them in the process. We can barely manage to get a tiny robot rover the size of a marble to land (see the link above for the picture of the “hopper” and “shape shifting” ball…curious about the “shape shifting” bit…)

Another failure from the private sector

“We continue receiving valuable data,” the company said in a statement, “and providing spaceflight operations for components and software relating to our next lunar lander mission, Griffin.”

Well, yeah, great. But the Peregrine lander still is a failure. Propulsion leak. Solar panels that didn’t open in time.

And NASA is counting on these privately operated products to get people back to the Moon? And they’ve delayed the Artemis again by another year?

When I was in school, we were all talking about people on Mars, living in permanent communities in the 2020s. And we can’t even get a tiny Moon lander to work right.

Sigh. And after BBC posted “Vulcan rocket” I so had my hopes up. (“The Vulcan rocket,” not “Vulcan rocket,” Spock 🖖)

There is a difference between being alone and feeling alone; being isolated and feeling isolated; being rejected and feeling rejected. Reality and emotive perception have no relation, except that which the mind projects. Eliminate the projection, and the reality allows itself to become revealed.

Only I can permit this reality to become revealed; only I can perceive, how can another remove this perception from me, if I cannot myself? No one can rely on me, if I do not rely on myself. No one can be helped by me, if I do not help myself.

No one can help me not feel alone, if I cannot do it myself. Being alone is a function of reality and circumstance; feeling alone is a function of myself, not dependent upon external stimuli. This feeling is one I must remove myself. I cannot be two, if I cannot be one.

O Isis OSIRIS-REx!

September 16, 2023
MThomas

Currently, OSIRIS-REx is located at a distance of 7 million km from our planet. On September 24, OSIRIS-REx will drop a capsule with samples of asteroid matter, after which it will enter the earth’s atmosphere and land on the territory of the Utah Test and Training Range.

https://universemagazine.com/en/osiris-rex-is-on-a-course-for-earth/

The tiny spacecraft launched back in 2016 and reached the asteroid Bennu in 2021.

One main reason for this mission is to find out what Bennu is made of. After the asteroid spewed out tiny “micromoons,” OSIRIS-REx successfully collected a tiny soil sample. By “tiny,” I mean less than 50 to 60 grams. And it couldn’t actually land, since the asteroid is too small to have enough gravity to support the spacecraft.

Now we have less than two weeks to find out what’s in the soil — assuming the capsule is retrieved without incident. And then OSIRIS-REx will head back out to visit yet another asteroid (Apophis) in 2029.

Yes, that famous “planet-killer” the media screamed about a few years ago as “the most dangerous asteroid in the world.” (uh. “in the world”?) It will “only” approach within 38,000 km in April 2029, but could possibly collide in 2036.

No problem.

A story must be more than merely a story. It must be an examination, of the human heart, of the mind, of the spirit. Of experience and existence. A simple recapitulation of one’s personal past or the delusional suffering of a dysfunctional suburban American family have no merit. Overcoming the reality we believe we live in, debunking fiction and elevating the truth, that is worthwhile.

Today I talked to virtually no one for the first time in quite a while. It’s almost like meditation. Reminds me of what L said when we were out drinking Friday night (as usual). She and G were talking about scuba diving, about how being underwater hearing only your own breath and hardly being able to see anything unless it’s right in front of you gives you a feeling of being alone in the universe, a feeling of vulnerability and isolation, of insignificance. I commented, “That’s just like meditation.” No reaction.

I don’t need to go scuba diving in the Philippines to experience such a feeling. 

Chandraan-3 rover finds…sulfur on the Moon?

September 1, 2023
MThomas

c/o ISRO

India’s Moon rover is making tracks…

One main reason for landing at the Moon’s South Pole is that the presence of water would help us build permanent settlements…

This region on the moon is an attractive place for humans to build a lasting presence due to the fact that water ice is located underfoot. Future moon-dwellers can potentially tap into that water for consumption, or even to create rocket propellant, instead of depending on water shipped from Earth.

https://www.space.com/chandrayaan-3-sulfur-surprising-composition-lunar-south-pole-soil

Another reason has now been found…iron, manganese, aluminum, titanium…and “surprisingly” sulfur. Why should they be surprised? It’s already been established that the Moon has ice, and sulfur forms every time hydrocarbon and sulfates combine. Plus sulfur obviously results from volcanic activity, and it’s likely the Moon was volcanic when it first formed. And sulfur is also produced through nuclear fusion – i.e., the Sun.

So what can we do with this knowledge?

Having a more complete chemical composition of the lunar south pole area means future travelers to — and possible inhabitants of — the region can also plan for what else they don’t need to bring from Earth. In particular, some scientists have suggested moon-dwellers could use sulfur in bits of infrastructure such as building materials, solar cells and batteries.

Hmmm…I think more studies are needed first…define “bits,” for example.

[Written during my first trip to China]

My legs, especially my left calf, still ache from Hua Shang. That experience alone justifies my whole trip. I walked 6 km starting at about 1pm. Stopping only once for maybe 15-20 minutes for a Sprite and a flashlight, I reached the North Peak (Bei Feng) at a little after 5. I really should have continued to the South Peak (the highest at 2160m), but at just before a particularly treacherous climb, a stranger offered to take my picture. He did this twice later; he then asked me where I was going, so because I told him North Peak, he led me to the North Peak Hotel. I signed into an expensive room, thinking a locked door proof against bag theft — but unnecessarily, as there were no other guests at all! I got a TV, a washbasin (no running water) and access to outdoor lavatories (Must have been the “private bath” the guidebook lied about). Public toilets basically meant an open outhouse shitting down the rock face — so much for sacred mountain vibes.

I slept and, waking at 4 am, set off to climb the Blue Dragon. Only then did I know why one traditionally climbed the mountain at night: to conquer fear. Once I began, I could not return. Grasping the iron-link chain with one hand and flashlight with the other, all I could see were tiny, steep steps underfoot and clear stars overhead. Most stairs were about 60º, but several inclined more, and at least one near the beginning of the Blue Dragon was almost vertical, certainly 80º. At the very end, just before the sunrise viewing point, was the actual peak (2100m). From atop an enormous boulder crowned with pine trees and a lone camp light came the voices of two crazy park workers, exhorting all to brave the true East Peak. A guide at the bottom told me to be careful before I attempted to climb the rock. But as I realized the steps were actually more than 90º, and that my pack was pulling me backward as I yanked myself up on the chains, I gave up and went down again after about 10 feet.

When I returned after watching daybreak, I looked down at the Dragon and could only marvel at my audacity; I had come alone at night, scared half out of my wits, with heavy packpack and asthma and glasses and only 1 free hand, and I had climbed steps narrower than the width of my foot. With sheer rock cliffs on both sides and only a single metal chain between me and a quickly plummeting death. I did it. I have nothing left to fear.

New (possibly) interstellar comet on a one-way trip…

August 24, 2023
MThomas

Comet Nishimura’s orbit means that this is likely its first and final trip through the inner solar system. It is possible that the comet originated outside our star system, which would make it the third known interstellar object ever detected, following ‘Oumuamua — which some astronomers speculatively suggested was an alien spacecraft — and Comet 2I/Borisov

https://www.livescience.com/space/comets/new-potentially-interstellar-comet-will-be-visible-to-the-naked-eye-next-month-before-leaving-our-solar-system-forever

Discovered just two weeks ago by an amateur Japanese astronomer (after whom the comet is now named), the comet Nishimura will approach Earth at its closest on September 13th. But it will be at its brightest about five days later as it approaches the Sun.

Its fate?

Astronomers don’t know when the possible interstellar interloper will depart the solar system. However, it is also possible that the intense force of the comet’s solar slingshot will rip its solid nucleus apart, according to NASA. 

Also, its nucleus gives off a “green glow,” which is the result of sunlight breaking apart dicarbon, or diatomic carbon. So getcher geek on, chemical lab rats!

Chandrayaan-3 successfully lands on the Moon!

Taken just prior to landing…the “image” shown of it actually landing was not real but a simulation.

India and Russia had been locked in a race to the lunar south pole. The Luna-25 spacecraft that crashed was the first moon-landing spacecraft launched by Russia’s space agency in almost five decades. Roscosmos officials said Sunday they lost contact with the lander after it fired its engines in preparation for a descent to the surface.

https://www.nbcnews.com/news/world/india-chandrayaan-3-landing-moon-south-pole-rcna101296

It wasn’t much of a “race,” tbh. India had been planning this for years, while Russia randomly launched a craft that had virtually no chance of succeeding.

Congratulations, ISRO! You should have some company over the next couple of years. Here’s hoping that international cooperation and not competition will lead humanity to permanent settlements on the Moon. Mars, and beyond…
