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.)
The craft is at a very awkward angle. A picture, captured by the small baseball-sized robot called Sora-Q – which was ejected from Slim moments before touchdown – showed the lander face-down on the lunar surface.
That left its solar panels facing away from the sunlight and unable to generate power. The decision was taken to put the lander into sleep mode – and conserve what power remained – less than three hours after it landed.
That tactic appears to have worked. A change in the direction of the sunlight has now “awoken” the craft.
As previously reported, JAXA did achieve its goal of a “precision landing” — as some put it, a “pinpoint” touchdown within 100 meters of the intended target — within 55 meters, although if all had gone as planned, it would have been within 10 meters.
That’s far, far closer than previous Moon landings.
Too bad SLIM is essentially standing on its nose. But at least this is a beginning. Japan has now become the fifth country (US, USSR, China, India) to successfully “soft land” an object on the Moon.
And the robots it brought with it are pretty amazing. And tiny.
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 🖖)
Way back in 2015, my good friend Rami Z Cohen came to me with an idea for a story. He had written two or three scenes about a group of asteroid hunters who stumbled upon something bizarre. The idea of mining asteroids was news at the time (and still is, although probably too expensive right now and not a worthwhile investment until we actually get some people in space who need metals without relying on NASA/ESA/JAXA/ISRO/etc).
So Rami and I began to email ideas back and forth for a few weeks, then we started to flesh out his characters and plot. I wrote a synopsis and outline and we hashed out the background.
ESA image. Gateway is planned to be much smaller and more cramped than ISS (about 1/6 the size).
NASA and its international partners see Gateway as a key platform to support the agency’s Artemis moon program and to build the technology required for future deep-space missions. Although the first elements of the small space station are expected to launch before the Artemis 3 mission lifts off in 2025 or 2026, NASA previously said that those astronauts will not use Gateway to “make that mission have a higher probability of success.”
While it’s a good idea to see some planning for this, I think maybe NASA should focus on getting Artemis 1 to work properly before they go on about Artemis 3 and 4.
Taking advantage of Gateway’s orbit far away from Earth’s protective magnetic field, three instruments will study risks due to radiation from the sun and from cosmic rays. Scientists hope this knowledge can help inform future long-term missions to the moon and Mars.
Since Gateway will orbit the Moon and not the Earth, the biggest problem will be preventing astronauts (and instruments!) from getting fried by solar radiation. Scientists need to come up with materials to shield people on Gateway and the Moon, or else we’re going nowhere…
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.
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.
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.
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…
“If we want to develop the Moon as an outpost, a gateway to deep space, then we need to carry out many more explorations to see what sort of habitat would we be able to build there with the locally-available material and how will we carry supplies to our people there,” Mr Annadurai says.
Chandrayaan-1 was India’s first successful Moon launch in 2008 — it deliberately crashed in order to measure the amount of water at the South Pole.
Chandrayaan-2 was only partly successful, as it did put an orbiter around the Moon, but the rover crashed. (The orbiter is still there, sending back information on a regular basis.)
Now, Chandrayaan-3 aims to finally land a rover and do some research exploring.
Let’s hope they can get it to land safely this time…
