The only differ of the JWST vs HST was the zoom range & resolution of the camera. Because JWST is a *weather space telescope* ( thermal sensor detection in pixel image), NO color, everyone was joked with heat variations into color scale. JWST is technically 23+years outdated concept, plus created twice. An unfolding glass fragile mirrors of a umbrella in space. Today you can do the same thing with individual relfect/refract telescopes vs each 18 hexagon JWST mirrors or 100+multi sets of insecta-eye position camera, zoom sync, you would get the same optic + more & resolution × sync special effects. Yet it would be far smaller, far rugged, far lighter then HST or JWST.
Well all I Know is this upcoming American Holiday will be filled with Bud Light Blackberry Seltzer Water! It's Healthy and Refreshingly cool! I only drink American Seltzer! But Bud Light Blackberry Seltzer is my Favorite!!
If Sagittarius A is facing head on towards Earth from our perspective, it makes me wonder if it were to really start to begin to get active again would the astrophysical jet be directly pointed at us? 🤔
My thought exactly! The way black holes seem to warp light around them so you can "see" the back side makes me wonder if they are really sure of the angles of view.
Why is the style of debris ejection from the asteroid surprising..? Genuine question! As that asteroid was only a small moon of the larger one, then it makes sense to assume its made of less stuff (obvs). I like to imagine it as a rice crispie treat, where all these big rocky pieces of puffed rice have accumulated together over time, leaving tiny "cracks/gaps" that are then slowly filled by fine particles or left over debris from previous impacts. Because the "finer stuff" is situated oddly in these cracks, that would then be the cause of the "random" expelling of material from the Asteroid upon impact. Please someone, tell me if I am being totally blind to the obvious reason as to why this is an incorrect guess? I'm genuinely not sure why they expected the small asteroid to be so "tough/solid", considering it's just an accumulation of variously sized materials, lightly held together by gravity/other forces. Am I being dense??? Fraser, could you clarify this?? Thank you!
QUESTION: If Dragon Hubble-servicing is feasible, I wonder if HST's retiring (Earth-pointing) NRO siblings could be upgraded and boosted as space-pointing HST replicas... and maybe even hold laser hands for some optical interferometry? Or maybe its more efficient to just put new stuff up?
@@martinzitter4725 Fixing telescope after 20 years in space is probably more expensive than building new one. Building costs are very high, because weight must be minimized. If we don't need to minimize mass, building costs will fall.
Fraiser, Did you ever know of or meet my grade school science teacher? Mike Reynolds. He was a top five finalist to go up un the fatal Challenger Space Shuttle. The reason he wasn't picked is because he knew too much and they wanted a more "lay person's" perspective. He was very active in the world of astronomy and the SOLE reason it keeps my interest. Of all my teachers, he had the longest and biggest impact on my life. One year in 8th grade changed my life.. Our school had an observatory. I mean a real one. It was building with a dome. Neptune Beach, Fl. (Jacksonville). It was 1978 so I can't quote the dimensions. But it was the largest telescope in the south east USA at the time. Mike passed a couple of years ago. He was the head of the University of North Florida (UNF) science department..... R.I.P. Mike for your influence. Thank you too Frasier for your teaching and updates.
What an absolutely MIND-BLOWING asteroid impact!! *Just NOW I realized, I saw it live, but at the time I brushed it aside and thought it was a rerun, of another mission lolol
Fascinating updates, thank you. You mentioned Europa will tentatively launch in 2024 and arrive at Enceladus in 2030. Is there a reason why it will take six or so years to get there, or would that timeline be considered normal due to the optimum course changes the mission requires? Does it have another side mission en route?
Europa Clipper was going to launch on SLS originally, but, due to all the SLS problems and its limited production rate (just enough for Artemis), NASA had to beg Congress to let them launch it on something else. That something else turned out to be Falcon Heavy. An SLS launch would've been more direct, while a Falcon Heavy launch means more gravity assists will be required. Wikipedia has the full details, I think.
This fellow is a model for all journalists to follow. He studies complex subjects and then describes them in a compelling way using language the average person can understand.
They were lucky that they found the culprit for all those prematurely failed gyroscopes on Hubble in time for the final (5th) service mission. Turned out the manufacturer of the bearings was using inferior materials and fudging the documents to save cost. So they ordered the bearings for the 5th service mission from a more reliable source, and these haven't failed yet, despite operating many times longer.
I say, use Starship to bring Hubble back down, overhaul it here, and re-launch it. That sounds "easier" (if more expensive) than strap-on engines. And you get a refurbished scope when you're done.
Regarding the brown dwarf with sand in it's atmosphere, how do we define/determine sand? I.e. what does the actual observation boil down to? Solid silicates?
Excellent video ! exciting times for laymen like me, who find most of the technology mind boggling ,But at the same time very exciting.Thanks for your dedication!
For asteroid mining, one of the biggest issues right now is the processing the ore into usable materials, couldn't we just do that step on earth? Move the asteroid into a gentle reentry trajectory, maybe slap on a simple heat shield and land it in a shallow lake, then pick up the pieces from the lake? You'd lose some material but wouldn't need the massive amount of infrastructure in space
Interesting space news week. I agree Hubble is getting pretty long in the tooth but it will be great if its life expectancy can be extended cost effectively.
Believe it or not, Enceladian geological features are named after characters and places in "The Tales of the One Thousand and One Nights" or simply "The Arabian Nights".
Gravity tractor is really the only economical solution. You not only divert it, over a long enough period of time you can park it in a useful orbit and use it as resources. That pays for the cost of diverting.
The ice moons are fascinating - even if I live another 25 years I'm not sure if they will find life on one of them before I pass on, but I sure wish they would. That would be amazing!
Yvette Mimieux still out there?!? 😰 They should have saved money by waiting for a real threat to use DART. Then, if it didn't work, we could always try again on the next one. 😜🤪 They're probably going to want to service the Hubble if they're going to rendevous with it. That takes a little more work.
1. Launch to space with minimal mass, but plenty of fuel. 2. Gather up some mass by collecting smaller asteroids or land on moon to get some mass. 3. With this new higher mass "craft", use moon and other planets to slingshot and gain speed to slam into a large asteroid.
I'm excited about enchiladas I seen all of the mission photos of the whole system, I believe there's living organisms under the ice all the organic compounds are there
I am sure it would be possible to boost Hubble’s orbit - but what about repairing and replacing the telescope’s instruments? The Telescope is well beyond its designed lifetime and has operated much longer than the expected 5 year lifetime after the last servicing mission in 2009, a launch I had the privilege of watching with the pilot of the first Shuttle flight 28 years earlier and 3 time Shuttle Commander Bob Crippen. It is no good boosting the orbit only for the instruments to fail soon afterwards due to the inevitable effects of operating for so many years in space. So how do NASA and Space X propose to service the Telescope now that the Shuttle has long since retired and therefore its payload bay is no longer available to hold the Telescope in position while repair and servicing missions are carried out? I hope it can be done, but we need to know how.
Just finished watching the whole of your video with a great deal of interest and wondered what the distance is from the black hole and this blob of gas, clearly not a small object travelling at considerable speed, i would suspect that it will take a while before the magnetic field of the black hole really starts to deforming this object, i wonder , as it is a gas in the main weather it will create as much game radiation as say a solid object. Great show, thanks a lot.
I wonder if the shape of plume reflects the spacecraft. Like where the fuel tanks were etc... you see this sort of thing with shaped charges or the pattern of the combustion in an engine tracing back to the arrangement of the injectors. It didn't have a uniform density.
Weather didn't delay SLS or cause it to rollback. Weather issues are a consistent thing in Florida. There failure to deal with the hydrogen leak in time is what caused this. If you sit on the pad long enough in Florida wind or lightning is just fact.
Cost of Hubble rescue mission vs Hubble replacement mission? Per year of service life? Accounting for better tech? I wouldn't be surprised if replacement wasn't a better deal.
No it's an emergent electrical vortex storm analogue to the red eye of Jupiter that churns through the ionized particle hub that orbits up to 2 AU from Sag*. It's not a discrete object, it's a ball lightning plowing through the dense inner accretion disk. That inner region is quite dense and very complex patterened due to coriolis storms. These coriolins storms take the shape of columns perpedicular to the orbit around the SMBH, and over time the columns join into one - then electrical fields coalesce into that column and the flow of electrical field is constant - a mixture between a particle accelerator and lightning storm. One day we will officially label SagA* to be "Azathoth" and this highly dynamic vortex will henceforth be labelled as Nyarlathotep. In a few decades we will discover HIGHLY anomalous emission patterns emerging from this disk region and for many centuries we won't know what causes these, only that there may be a very strange "mega engineering" component at work here. Something is intentionally doing something something with intent and purpose there, and it has been doing so for millions of years at the very least.
If we go to Saturn's moon we should introduce/inoculate some building blocks for life/microbials, plant and animals. Might serve some interesting data in the far future.
Momentum of Dart was passed onto Didimoon. This transfer was exactly known before this experiment. But energy of Dart kicked some material away from moon. How much this kicked it is unknown.
Hey there Fraser, you crazy cosmological man! Just curious: what is the closest that Juno could flyby Europa, and still have sufficient escape velocity? For example, could it buzz that world at say, 100 km's above? Would also be really nice to see a more gentle/slow crash of Juno, eventually into Europa at mission end. I know NASA is worried about contamination, but it's hard to believe Earthly bacteria would survive being splattered across the surface of Europa, and then a subsequent prolonged possible multi-million year journey down through miles and miles of ice, to the ocean below? Could it?
1st priority would be to raise Hubble's orbit so that when something breaks or some consumables are all consumed out even if it's further away there will be less of a "it was a good run but now it's over" argument that would give those who don't want Hubble to say that now's the time since it's low.
