Another mission to check out is the upcoming SunRISE mission to study CMEs, or coronal mass ejections from the Sun. The mission is going to involve a fleet of 6 small "cubesat" spacecraft to study solar radiation and charged particles in the solar wind. Recently there was a public talk on the mission released by the Jet Propulsion Lab that goes into more details. Fun trivia fact.. Anime fans will probably recognize the name Sunrise in a different context. The mission naming is a complete coincidence, but there are anime fans working on the project and they've had had a bit of fun with it. As I've posted before the 6 spacecraft are informally named after Cowboy Bebop characters.

Congratulations to India on successfully landing their craft near the south pole of the Moon. It'll be interesting to see what pictures and data it's rover vehicle sends back.

Space ships, rockets, robots, a unique metal world.... what's not to like?

Full article here (nasa.gov). This is something that I've been thinking for a while now, ever since Mike Brown at Caltech started coming out with his data on dwarf planets in our own solar system. We have already observed hundreds of potential dwarf planets there, and given the difficulty of making such observations and the fact that the volume of the space we're talking about there is so huge then there may very well be thousands of such planets, many of them Mars-sized or even larger. Thing is, at such huge distances from the sun the orbits of those planets are only very loosely coupled to our star. Even here in the inner system there is ample evidence that the orbits of even Jupiter, the largest planet, have been disturbed at some point(s) in the solar system's history. It would not take very much of a disturbance to knock planets both 100s of times smaller and further from the sun than Jupiter loose entirely and turn them into rogues. Over the billions of years our solar system has wandered the galaxy there must have been many opportunities for such disruptions. It may even be that -most- of the planetary real estate in space is not in orbit around a star. It will be very interesting to see what Roman comes up with. Before Kepler we only knew of a few extrasolar planets. Kepler found thousands more, but its search method could only find planets orbiting stars. (And even then it was biased towards very large planets.) Roman gives us a whole new method for finding extrasolar planets. I can hardly wait to see what it can tell us. Edit: Here's a 'tubie on the same subject..

Not sure I'm on board with the "new physics" aspect but I do agree that it is definitely interesting data.

A recent analysis of Betelgeuse data suggests the star is in the late stages of core-carbon "burning" in terms of nuclear fusion. That would mean that it may be only decades away from going supernova, not centuries or millennia as has been previously supposed. That would be a pretty awesome sight to see. Paper Here

Or at least they think they know it is connected to oscillations in the planet's magnetic field.

Where's Wald.. er.. I mean Ingenuity. (Hint... it's right there next to the rock.)

New details of the ~350yo supernova from the James Webb space telescope... https://www.esa.int/Science_Exploration/Space_Science/Webb/Webb_reveals_new_details_in_Cassiopeia_A

This one ought to be good for a few dramatic moments, including the landing and launch from Mars caught on camera by the rover. https://mars.nasa.gov/msr/

This post will contain spoilers for the anime Madoka Magica, the 12 episode anime. I just recently finished watching the anime episodes of Madoka Magica, which gives a take on many philosophical questions, one of them being related to physics and I really thought it was worth exploring. The problem is as follows: In this universe, there's a civilisation of seemingly advanced magical creatures that are described as feeling no emotion (or those that do are considered mentally ill), and they wish to make 'progress'. They have sought means to harvest energy to make up for the rise of entropy for a long time, and their answer was to harvest the emotions of the human race. Their sadness, rage, happiness, their whole souls, basically. They do this by providing each person who makes a contract with them magical powers, turning them into a magical girl. Once they give up their soul, the human is subject to harvest energy from distorsions in reality that corrupt and cause the suffering and death of people. It doesn't sound too bad... does it? Later, it is revealed that the humans are eventually destined to return the good they've done for the world, in the opposite way. Because of giving up their soul, they are prone to losing themselves and becoming the very distorsions they used to destroy, only this time causing all the pain back that they once thought they avoided. The advanced civilisation creatures don't care, for their lack of emotions, and they've been thriving off of humanity's suffering for as long as history knows. My personal belief is that when the question comes up, 'what's the price of an eternal civilisation?', my firm answer is that there is none that are worth the exploitation of other beings. The exploitation of other planets, living creatures. I believe the universe should die at one point. Entropy does its thing, and that will be the end of it. If you were given the choice, would you accept to extend the life of the universe? If so, what's your purpose and reasons?

A new asteroid named "2022WJ1" was detected.. and just a few hours later detonates in the air over Niagra falls. Barely even enough time to say, "oh, shit!" Fortunately it was only a few feet across. The real news here of course is that it was detected before impact. This is only the 6th time we've managed to do that. As usual Scott Manley has some good coverage of it in this week's space summary.

“It is surprising that people do not believe that there is imagination in science. It is a very interesting kind of imagination, unlike that of the artist. The great difficulty is in trying to imagine something that you have never seen, that is consistent in every detail with what has already been seen, and that is different from what has been thought of; furthermore, it must be definite and not a vague proposition. That is indeed difficult.” —Richard Feynman The Quotable Feynman (ed. Princeton University Press, 2015) - ISBN: 9781400874231

"Here we present 4.5 yr, 16-band photometry of Betelgeuse between 2017 and 2021 in the 0.45–13.5 μm wavelength range making use of images taken by the Himawari-8 geostationary meteorological satellite." Cool stuff, at least for a space nerd like myself. (And yes, this is what I do for recreational reading these days. I might need professional help. ) https://www.nature.com/articles/s41550-022-01680-5

Just a concept at this point but wouldn't that be cool? The mission would even include a probe to drop into the planet's atmosphere. I'd want to see Triton close-up too, though with its orbit it might be difficult to get anything more than a few awkward flybys.

If this holds up it would be an amazing find!

(Been looking at latency numbers for the past couple weeks at work. Nice to see results.)

Interesting theory. Nice tie-in with string theory too. Is ST finally becoming useful?

Impressive explosion no doubt, but quite a lot of interesting science to be done as well. No doubt there will be more info coming out momentarily but as usual Scott Manley does a pretty good job of putting together a summary and initial commentary on the event..
