Despite beliefs of crazy life on some crazy planet, if there was a planet like our somewhere out there, and its pretty likely given the amount of stars we see out there, life there would certainly mmic ours at some stage. we are the model of what life is in the universe.
thank you very much ! I was searching about this topic and I had many doubts, now I would say Catherine solved them all in this video, it was very clear!
Hi I am an Architectural student from De La Salle University Dasmarinas, currently taking my thesis entitled " Artificial Photosynthesis R&D facility " which aims to pursue PEC prototyping, can I ask for your expertise, that can provide pivotal information towards an R&D facility.
SP7 wax fuel was never well characterized. Wax has low melting temperature, shrinks and cracks... it is just structurally bad compare to polymer alternatives. Equally important, thay failed to understand the combustion process, following traditional well documented challenges with hybrid propulsion...would lead them to fight O/F-shifts, less performance and combustion efficiencies. The biggest failure in my mind is that the team failed to see the that by choosing hybrid propulsion for this case with fairly low TRL and IRL, they had to cover a more lengthy and costly development path compare to choosing either state-of-the-art liquid or solid propulsion.
Wow talk about overcomplicating it I can tell you exactly how frequency com works how it's formed and how it deforms I can tell you the building blocks of frequency combs something fundamental I discovered not too long ago. also a basic understanding so basic you'll be amazed just by using multiplication formula. a frequency comb based on a gear or clockwork is a complicated approach to something that is not what it is with the uncertain formula that will give you uncertainty is absurd. Frequency and magnetic attraction has something that's very similar to each other. like frequencies cancel
Great presentation! Thanks for the fantastic slides and explanations! Is there any updated version which contains the DFG process instead of the f-2f-self-referencing?
It's amazing that so many people (including me) are playing the computer game Kerbal Space Program (often with Realism Overhaul etc) and only so few of us seem to watch this excellent presentation explaning how the real Mars probes are designed and why. Then again we have youtubers with hundreds of thousands of view just showing rather boring construction work on the SpaceX Boca Chica site. Maybe we can learn that making a presentation video like this is a great start but there is just a bit of extra work to do e.g. to collaborate with the famous space-youtubers to get (some of this) presentation work in front of a larger audience. Anyway thanks a lot for the interesting presentation.
Great stuff. The SparkFun tie-up should expand the market for you even more (that's how I got interested). I'm particularly keen on remote camping and emergency scenarios. InReach does a decent job of those, but your cost model is better. More important IMHO is your open APIs on the cloud and device sides - that will allow lots of inovation. Thank you!
Interesting historical summary. I guess all dreams we have in the present people have had for a long time. Hopefully it gets off the ground soon, at least before the Voyagers go silent.
I had just been born when the voyagers approach to Jupiter. When I was five years old, my dad took us out to West Texas to visit the McDonnell observatory. I can still remember looking through the telescope, First at the craters of the moon, and second at a distant star cluster. What made the strongest impression on me though was in the gift shop of all places. I remember seeing all of the posters and books festooned with beautiful photos of Saturn, taken during the very recent Voyager fly-bys. My mom even bought me a little picture book with that one particular false color image of Saturn. You know, that image that makes it look almost like a rainbow. To my five year old mind, that must’ve been what the planet really looked like, and I absolutely loved it. My favorite image of Saturn now is the backlit panorama of the rings taken by Cassini. My dad bought me a subscription to astronomy magazine, and I remember eagerly awaiting each new issue to see what new pictures we’re coming out from the voyagers. From Uranus to Neptune. Even though I was far too young to of had any sort of connection with the Voyager program, for some reason I always felt a very deep emotional attachment. I remember being really upset when I found out the Voyagers would never come back to earth, but would be lost forever in space. I have not yet read Jim Bell‘s book, but I plan on picking up a copy. I really enjoyed the Farthest documentary also. That kind of took me back to when I saw many those images for the first time. The Voyagers have definitely shaped my own interests in astronomy and science. And by extension, they are helping me to shape the interests of my own children. It still amazes me, that after all this time, those two spacecraft are still functioning so far away from the planet that sent them. Truly one of the most amazing accomplishments humanity has achieved.
@CTU/crooked feds-remember this? I wrote software to do any of what you see here in components to be arranged in any order you want. It's in the public domain but you bitched and called it classified! You tell me my stolen degree is classified so you can try and shove me into your illegal political shit? Then I suffer? That's what's classified! Cover up the illegal stuff you're doing, make me the fall guy, kick me aroynd and what the hell does the FBI do? Watch and tell me to do your job and interfere with me telling DOJ of your crooked stuff?
Honestly I don't know how I got to this video. I'm not in astrophysics. I guess I've just been thinking a bit too much about black holes and dark matter. I'm just an artist. Good talk (8 years after the fact), send help.
PYRAMIDS: Perhaps we should build space habitats, on the Moon and Mars, just as our ancestors built the pyramids. They are the most economical use of 3d printing, inflatable habitats, and multiple story building. They also provide the most economical and quickest way to guard against micro-meteorites and radiation. You must ensure that you can move machinery, equipment & stores to the appropriate level within the habitat, and pyramids provide a smooth ramp to every level. This approach basically involves blocks of polymer-infused regolith, surrounding a space filled with tamped loose regolith, containing walled empty space for habitation, or even just stacked inflatable modules, and a helical ramp just inside the blocks, with access to each level, to move things around. Robots could collect and distribute regolith, make blocks of amalgum, tamp regolith, move equipment critical stores and habitat structural elements into place. And just why would you need windows, if you have cameras outside and video projectors inside the habitat? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-j4cdDT1ZvAA.html
