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…
A NASA mission has observed a supermassive black hole pointing its highly energetic jet straight toward Earth. Don’t panic just yet, though. As fearsome as this cosmic event is, it’s located at a very safe distance of about 400 million light-years away.
The two planets are in circles that kind of look like, er….let’s just call the whole thing a cosmic donut (the outer “halo” is the protoplanetary disc of gas and dust from which planets eventually coalesce).
We already know that more than one object can share the same orbit; Jupiter has a collection of 120,000 asteroids following its same path around the Sun, for example. Earth has one, too. But although it’s theoretically possible, astronomers have never discovered two whole planets sharing the same orbit around a star before.
Hmm…the language here is a bit misleading. The two objects are technically not both “planets.”
The article comments later on that the object in the dotted line circle is “a cloud of debris about twice the mass of our Moon trailing a bit behind the innermost gas giant” in one of its LaGrange points (where “Trojan” asteroids follow gas giants such as Jupiter and Saturn). So it’s way too early to say that “two” planets formed in the same orbit.
Still, this is the first time that astronomers have spotted two such objects this close to one another in the same orbit. Who knows if both will remain viable (the debris cloud could become partly or mostly absorbed by the gas giant with the rest either being expelled or thrust into separate orbits).
So why is this called a “cosmic unicorn”?
Apparently because although such Trojans “are allowed to exist by theory, but no one has ever detected them.”
Um. OK.
So, like, totally NOT at all like this? Kind of a bummer, really…
“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…
Scientists have suspected for a long time that this tiny moon of Saturn may be the best place in our solar system to look for life.
Now they have confirmed evidence of all six crucial elements necessary for life to exist (life as we know it, anyway): carbon (C), hydrogen (H), nitrogen (N), oxygen (O), phosphorus (P), and sulphur (S). If present as a phosphate, essential for DNA and RNA to exist, the discovery of phosphorus on the 310-mile-wide Enceladus may indicate life of sort sort, perhaps at a microscopic level beneath the icy surface.
One guess is that the oceans of Enceladus have at least 100 times more phosphorus than the Earth’s oceans. That would make for quite the carbonated fizzy pop. Methane has already been seen coming out out of various “ice geysers” (a.k.a. cryovolcanoes). Since methane results from rotten organic material, there logically should be something alive out there.
Now we just have to get back out there and figure out a way to find them.
Of all the asteroids they modeled, the one with the largest risk of impact was a kilometer-wide asteroid known as 1994 PC1. Over the next thousand years, the probability that 1994 PC1 will cross within the orbit of the Moon is a paltry 0.00151%, hardly worth worrying about.
Thanks to Glen Hill over at Engagin’ Science (formerly Scientia, which apparently was far too Latin- and science-esque for search engines to handle) for bringing this (not-so Earth-shattering) info to my attention.
Sorry, folks. Hollywood was once again wrong (sigh).
…Ispace engineers observed that the estimated remaining propellant was “at the lower threshold and shortly afterward the descent speed rapidly increased.”
Led by the European Space Agency (ESA), the mission will orbit the largest planet in the solar system and explore its icy moons, which scientists think could support living organisms.
JUICE will explore three possible ocean-bearing moons – Europa, Ganymede and Callisto. Under their icy surfaces are thought to be huge oceans of water – a crucial ingredient for life as we know it.
The “Jupiter Icy Moons Explorer” is the first time an ESA-headed project will visit another moon.
If it launches successfully, of course.
Lift off in less than seven hours from French Guiana!
Great job by Alzajeera, although “Earth is about 4.1 times the size of Europa and is believed to have a young and active surface that may vent water vapour to space via plumes and geysers.” is a bit misleading (Europa, not Earth, is believed to have…)
The astronauts will be the first humans to fly in the vicinity of the moon in more than 50 years. They will also be the first to launch aboard NASA’s next-generation megarocket and Orion space capsule. The crew will not land on the moon but will swing around the celestial body, testing the performance of the Orion spacecraft, before returning to Earth.
