Oops. I said meteors per minute, but I meant meteors per hour. I can't believe both Anton and I missed that during the edit. I wish it was 150 a minute - a full-on meteor storm.😞
When I heard that I literally did a spit take. Started wondering if I could convince my wife to go out for a winter camping trip out west to watch this meteor storm!
Questions for your Monday questions show. is there ever an encounter a blackhole can have with another object and lose? (be destroyed) Is an antimatter black hole possible? If we could move an antimatter blackhole and push it towards a regular blackhole would the explosion be powerful enough to cause the blackhole to lose enough density to stop being a blackhole? I've recently seen some new youtube channels with titles like "750 new galaxies found beyond the observable universe!". I realize that these are largely ai channels with clickbait titles, so I always block them from my feed, but is there a way to actually detect things beyond what is beyond the observable universe based on its interaction with things we can actually see? I feel like star trek has lied to us. If we were actually able to move at warp speed through space, is there any possible way that we would be able to see things the way they show it on TV? If we're flying at warp speed, and trying to shoot another ship ahead of us, what good would phasers be when they're going faster than the speed of light? Thanks!
@@Jameson1776 again this is why I blocked them, but while I'm sure we can't see beyond it, and that's why we call it the observable universe, I'm wondering if there is any way to infer what might be there based on gravity or something else, even if we can't detect it currently.
They can't even build bridges and buildings properly yet they launch stuff into space. Check out The China Show to see how bad their building quality is.
@@I-0-0-I The CCP only cares about things that further their agenda. If their rockets crashes against other rockers, they feel better that it's not their concern.
Remember Gilligan's Island back in the day? Starliner is like the boat that took Gilliigan 'and company' to the island (a 3-hour tour). [of course the boat worked fine, it was the storm]
FYI: C3PO really sucked at math: The chances of successfully navigating an asteroid field are 100%. The average distance between objects in our Asteroid Belt is a nice round figure: 1,000,000km - or 2.5 times the distance from the earth to the moon.
150 _visible_ meteors per hour perhaps. but I'm sure there are 150 pieces of space debris becoming incandescent while coming into that atmosphere per minute, so technically correct even though your eyes didn't detect them?
@@apple54345 Meteoroids: These rocks still are in space. Meteoroids range in size from dust grains to small asteroids. Meteors: When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. Meteorites: When a meteoroid survives a trip through the atmosphere and hits the ground, it’s called a meteorite.
people also forget the ramp up and down and usually only go at the maximum and then it´s inevitably gonna be cloudy. been catching some very nice perseids already
Unfortunately the wildfire smoke makes seeing meteors in the summer a lot harder. The ones i do see are definitely shifted to red/orange just like a sunset.
@@asymdelegate Are you asking whether they are at risk? The answer to that is, the increase in risk is almost nothing. It IS a small increase, but tiny.
Not sure why but this made me think of the time I towed one of the larger asteroids into a Kerbol Orbit in my KSP 1 (modded) that was extremely elliptical and screamed through the upper atmosphere every orbit at about 80km closest approach. I thought it looked very nice.
I have a question for you that is a little bit more technical: Who is creating all this stock footage and 3D models of planets galaxies, asteroids and so on. Do the space agencies hire artists that work for their communication department, or is it independent creators or scientists ?
Moon atmosphere.As I understand it, space walks have the spacesuits using pure oxygen at 5 pps. Could the spacesuit be replaced with spandix applying the pressure instead of oxygen? Of course some kind of fish bowl would be needed for breathing.
11:45 For comparison, the distance from the Sun to Saturn averages 9.5 AU and from the Sun to Uranus averages 19.2 AU. Our outer planets have large moons that would be analogous to planets in that system.
1:15 As I understand it, a trail sort of follows a comet because of other influences. The trail also gets wider like a contrail from a high up jet. Eventually, the comet can be in parallel with an earlier version of it. Also, the comet can produce voids in the trail by affecting one part so much that it doesn't meet up with the Earth for many cycles around the Sun.
Boeing Starliner: Next launch to the ISS they send up the guy who decided that NOT installing remote systems was a good idea, and He gets to fly it back ... .. . 🏔
Can you expand on what makes Starship such a game changer over the Falcon 9, capacity aside? Thank you So much for your podcast! It is my all-time favorite.
the idea is that it can take that large capacity, and send it to the moon, or with an in-orbit refuel from a second one, send it to mars. The large capacity is the object, the rest of the ship is for the goal of using that cargo space to multiply its usefulness on missions. This is huge because we currently have trouble sending a couple tons- it'll increase single mission size to nearby planets and our moon by about 5x to 10x, if all goes well, or even further *or faster* if they use a smaller payload. I wonder... what kind of things don't do well in a tin can in space, but want to land quickly? I think the mars plan is to use about 5-6 launches to send some beginning supplies slowly and efficiently, then 2 more launches to send a barebones manned cabin as fast as possible. that's how I'd do it, anyway.
@@nubnubbud Thank you for the reply. I am eager to see how it all unfolds. I love the rate things are happening to today and how much is being learned. Exciting days ahead!
It worries me a bit when people talk about mining for water on the moon or on asteroids for the purpose of fueling spacecraft - because it's technically not a renewable resource, right? Do we have any estimates on how long water on the moon will last under a complete colonization, depending on how we use it? What about in the solar system? And is water being replenished in some capacity across the solar system?
Hi Fraser . Here in Australia it’s winter , yes, but right above us is the centre of our galaxy Scorpio and Sag, they have many clusters and nebulas to view , Saturns rings are edge on , it always looks odd to me when it’s like this. So yeah winters alright for me. 🙏🏼🥁🌟
Never realized graphine is that recent. Having been thought of it decades ago by an arts teacher, when I used s non permitted pencil in a colour drawing to give sheen to part of an eye. Graphite is amazing. Structure it right and you get graphene or diamant. Remember people convinced we could never make diamant out of it. Sure we can, I said. They tried and succeeded. Never say can't be done. Think how could it be done. You might fail at it. But assuming it can't be done brings no innovation for sure.
Why don't they send the next CrewDragon up with 6 seats and just have 2 of them empty or strap some extra cargo into the seats? Maybe put a tow hook onto it so it can hook onto Starliner and tow it away from the ISS. Edit: before someone says it, the second one is /S
They didn't just bring back rocks. The also brought back lots of regolith. The made a bunch of core samples which sampled the soil several yards deep into the moon's surface. I'm surprised China found graphene when NASA didn't. NASA might want to recheck some of the sample to see it there any they have in storage. They still have lots of the stuff.
I've never had the pleasure of seeing the perseids. I'm going to be imaging the heart and soul nebulae soon, which are close to perseus, I hopefully will catch at least one of them on an sub. Although, seeing as starlings exist telling them apart is difficult.
Thanks for acknowledging there's another hemisphere, Fraser. Other channels just said the Perseids are the best because it's summer. Okay, I understand there is no time for these clarifications, but you did it.
I saw two shooting stars, two unknown man made craft with steady light and 3 aircraft. We call this phenomenon "rain of stars", and I think it is over-rated. They are bright enough to see within a city. The Moon was off.
The TV show The Ark mentioned the Trappist 1 system. It's an ok space show...if you don't wear your scientist hat. There are a lot of inaccuracies, but it's still a fun ride.
Apparently that’s a bit of a concern if they don’t use it for the return bc they have to upload the remote/autonomous control software to return it unmanned and there’s a risk it just bricks the whole control system.
Moon Mass discplament of space/gravity complexities mixed with environmental decay onsome order of magnitude scale or degree is expected . Perception management of the day was just extreme and it was so weak it was drowned out in passing. To really get inside up close views of these planetary systems will truly help answer much more grand questions we struggle with. And the oxygen rocks along with elements & processes jwst surprising us with do really spark the need for raising up today's kindergarteners to become a judgment of reform using all these new computational tools of hardware we will be building out the next couple decades.
What happens if there is some type of emergency on the ISS, and Starliner is still docked to it? Can Starliner be disconnected/jettisoned in short order?
$*it happens, at some point we need to find a way to mine all the debris. China not the first one to leave garbage in orbit. Can you imagine if there was alien visit and they see all the trash in orbit.
Moon graphene is interesting to me but less as a resource than as something that could potentially be a product of space industry. What if graphene could be produced in earth orbit?
Long March is a pretty mature system. I wonder if they tried to copy the SpaceX dispensing method? That is spinning the second stage before release, and overdid it?
I know how much you love "Why don't they just...?" questions. I also know that at present the dragon and Starliner docking rings are incompatible (according to Scott Manley), but why don't they just modify a cargo Dragon mission with a compatible ring, dock with Starliner and deorbit it safely, if they can't get Starliner's hardware to behave within safe margins. They can then separate and Starliner can still perform re-entry and landing autonomously as if nothing happened, but most of the concerns from NASA I hear are concerning near-ISS maneuvers and the full performance of the deorbit thrusters. If that part of the risk can be handled by the Dragon, then Boeing can have its bird back and no one has to worry about the safety of the ISS. Of course, that requires the Cargo Dragon to have enough spare delta-V to deorbit itself and half-fueled Starliner.
If accretion disks on binary stars are orbiting on the same plain, and conditions are just right - in regards to lengths of orbit - could the stars swap planets on a regular basis? Could some stars have 'figure of 8' shaped orbits?
Is there a pattern of China’s satellites in the higher altitude behaving fine but those at the StarLink level breaking up? Are they taking out the competition?
In the video there's an animation of meteors streaking thru the sky and they're mostly going in a similar direction but some are at very different angles. When I look it up the internet says they pretty much go the same direction. So, are the radically different ones in this video a mistake by the animator or is the internet not keeping up with times. A little help please. Thx
I have filmed the moon's blue glow hundreds of times. It's quite beautiful when you get zoomed in on it and you can see the color change with your own naked eye. You get a better picture of it using a cell phone or a DSLR camera. Technically the the Moon is still within the Earth's atmosphere but it has enough pool to capture its own atmosphere as well.
I think there are problems with the dark oxygen story. I don't see how those nodules could possibly be splitting water into hydrogen and oxygen for more than a few weeks. The act of producing the voltage to split the water would cause corrosion of the nodules. The story sure sounded fishy to me.
That ISS external camera recording the docking is either end of life, or it is a Russian SECAM camera and the receiver is assuming it is either PAL or NTSC... In both cases everyone would probably be a lot happier if it got replaced with a GoPro.
cargo dragon has the capability to get to the iss without anyone on board. I would be very surprised if crew dragon does not have the same ability. I see no reason why a crew dragon cannot go up as a resupply mission and Butch and Sunni could return on that. suits could be carried on the same mission. there is no reason for there to be a missed mission just get the star liner out the road so they can return safely. once the dragon has been unloaded there is no reason for it to stay at all.
@frasercain thank you! It just occurred to me that China hurts themselves if they polute their intended orbit so I would like to think they will try to make sure this doesn't keep happening
as to your question of what is the difference between an asteroid and a star... how about one reflects light from other sources and the other IS A SOURCE OF LIGHT!!!!
question is how high quality is the graphene on the moon?! this is natural accruing graphene that's amazing yet I'm wondering how high quality these things will be!
I got up early and went outside to watch a good meteor shower, but these pesky bright streaks kept zipping across the sky and distracting me. Oh well, maybe next time.
