A robotic spacecraft made history Thursday becoming the first privately built craft to touch down on the lunar surface, as well as the first American vehicle to accomplish the feat in more than 50 years.
A study published this weekend in the journal Monthly Notices of the Royal Astronomical Societyproposes that the oldest star in the Milky Way is a faint white dwarf that is about 10.7 billion years old and shining roughly 90 light years away from Earth.
Mimas, the smallest and innermost of Saturn‘s major moons, is believed to generate the right amount of heat to support a subsurface ocean of liquid water
But it demonstrates the fact that water may in fact be common in space, opening the possibility of finding life on celestial bodies with older (much older) water sources.
(FYI: Mimas orbits Saturn once every 22 hours, and is affected by tidal forces from Saturn that appear to have melted part of its icy surface.)
OK, so my post about a big ole spider got the most likes of any post in ten years of blogging about science.
I have so not got the zeitgeist of the 2024 blogosphere lol – anyway, thanks, all, for the “likes”! Although one person used AI to write a very meaningless comment about arachnophobia. What’s the point, man?
By the way, back to science and space stuff. I forgot to post about the Europa Clipper project back in October.
So here you go. (It’s too late to add a message, but the project obviously is going to take some time arriving there, and you can supposedly hear US Poet Laureate Ada Limón read her poem online, although I’ve had trouble with the audio lately:
“Arching under the night sky inky with black expansiveness, we point to the planets we know, we
pin quick wishes on stars. From earth, we read the sky as if it is an unerring book of the universe, expert and evident.
Still, there are mysteries below our sky: the whale song, the songbird singing its call in the bough of a wind-shaken tree.
We are creatures of constant awe, curious at beauty, at leaf and blossom, at grief and pleasure, sun and shadow.
And it is not darkness that unites us, not the cold distance of space, but the offering of water, each drop of rain,
each rivulet, each pulse, each vein. O second moon, we, too, are made of water, of vast and beckoning seas.
We, too, are made of wonders, of great and ordinary loves, of small invisible worlds, of a need to call out through the dark.”
The so-called Big Ring has a diameter of about 1.3bn light years, making it among the largest structures ever observed. At more than 9bn light years from Earth, it is too faint to see directly, but its diameter on the night sky would be equivalent to 15 full moons.
This is important because it contradicts the so-called “cosmological principle” that everything in the universe is basically evenly distributed.
Just thinking about it, though, it makes little sense to assume that galaxies are all evenly spaced. Assuming the Big Bang was a single point should not imply even spacing of anything.
FWIW the “Big Ring” is evidently more a corkscrew shape, directly aimed at us. Evidence of “cosmic strings”? Maybe.
This is not as interesting as technology that will allow us to build hotels and colonies at LaGrange points or communities on Mars, but it’s still interesting. Sorta. Maybe?
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…)
“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.
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.
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.
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.
