Despite what Elon Musk says, colonizing Mars will most definitely accelerate climate change on Earth, & the YT algorithm is clearly smart enough to know this 😂
Honestly, these bots do way more harm than good when it comes to drawing attention to issues that we should actually care about. They take way too many things out of context and overall damage otherwise worthwhile narratives and causes.
A "Brief" history of Mars Opens video - ~1 hr 45 min. That's the undersell of the year in my book. I am going to have to break it into a couple viewing sessions but it's great so far. But then again, I expect nothing less. Your content is always top notch; all the facts and nothing but the facts.
As part of the New Jersey General Electric team that decoded the final temperature telemetry for the mars spacecraft that exploded propellant lines around Mars, we saw some pretty high temperatures. It turns out that O-ring seals for valves normally opened after launch allowed fuel and/or oxidizer to pass through the O-rings into the feed lines for the thrusters over the course of the interplanetary trip. It was a communications satellite bus pressed into service as a Mars orbiter. Our Denver branch mixed up the english and metric units. Thanks for the retrospective. Extremely well done.
Currently listening to this while part of a sailing crew crossing the Mediterranean. One, thanks to starlink. Two, makes me think about what future crews crossing the sea of space between Earth and Mars will endure.
My guess on SpaceX's proposal is "We'll do it with Starship". You know, just in case it gets anywhere near Mars before the end of the decade (It won't, by the way, SpaceX has done fairly little space exploration for a company which literally made that its name)
That is their proposal. I can't imagine why a for-profit launch provider would go off doing scientific work on their own, without anyone paying them to do it. They're not a space agency and that's not how any of this works.
@@DKiSAerospaceHistory Well, if they wanna put colonies on Mars, they're gonna have to send those probes eventually. Just saying. Sure, they could wait for NASA to lay the groundwork for them, but try going up to investors and saying "Yeah so we could send our own probes, but that is, like, expensive, so instead we'll just wait until others get around to it. I swear we'll colonize Mars eventually though!" and then convince them to give you funding for the project. Hell, even if they fund it out of pocket, and if Starlink ever gets anywhere close to what they want it to be, they probably could, our current scientific understanding of Mars isn't anywhere near where we'd need it to be in order to build anything resembling a self-sustaining colony. Before you can even think about going there, you're gonna need to find a good spot. That means finding a good water supply (I don't know about you, but scraping the entire surface of Mars off to get to the water ice beneath it doesn't sound like a sustainable plan long term) nearby sources of all the materials you might wanna have, ideally a lava tube for shelter in case of solar storms, and in the middle of all that, a nice, open space to build the colony in. We are still at least a decade away from finding such a place, simply because anyone has yet to send any sort of equipment geared to actually finding such spots. And that is not even mentioning all the orbital infrastructure you might want to have in place before placing your colony down. And sure, you can wait for NASA and others to send those probes, but do you really wanna wait that long when you have the technology to build and send those things here and now? Same thing for colonizing the Moon. They have the tech to start doing the groundwork for that now. Why wait for NASA and others to do the groundwork in however many years it takes Congress to push the funding for it through when you could get started on that today and get there before NASA even gets approval? Not to mention we'll need to do long term work on the Moon anyway, just to make sure all those fancy systems we think up for Mars actually work. The Moon isn't a perfect analog, but it's closer than Earth. (And yes, i know about Artemis, but that's hardly comparable; we're talking about astronauts staying for a few weeks at a time vs long term habitation, ISS style, plus extensive mining and refinery efforts, that's an apples and oranges comparison) And besides, every tech company has an R&D department, but if you don't even know what you are researching and developing for, you can't do R&D, so these things would be neat to know ahead of time.
Without SpaceX's rockets, American space exploration efforts would have fallen behind the Chinese space agencies years ago. They build and sell spacecraft to explorers, the company itself doesn't do the exploring. A small fleet of Starships flying back and forth from Mars every transfer window is a whole new level of exploration compared to throwing one experiment at a time on modified ICBMs.
I've volunteerd on a JPL-project at Zooniverse to help building an AI-model which should assist the next rovers with autonomously driving on Mars. Getting images to classify with parts of Perseverance and Curiosity in high detail is very interesting, made me appreciate everyone behind these incredible projects even more! Our work increased the accuracy from 41% to 91%, can't wait to see these next generations of rovers in action.
Sojourner is still my favorite rover. I remember in early middle school, we had an assembly where someone who worked on the program spoke on the program. I think that might have been one of my favorite assemblies ever.
Thank you for this very comprehensive history of our exploration of Mars. I've been fascinated by the Red Planet since I was a kid, mainly because I have a personal connection to one of NASA's programs - my grandfather worked on the Viking project. In fact, I think he was responsible for my very early interest in science and space.
I came here from Venus - your Venus video, in which you cleverly mention this video. I refuse to say advertise as this implies overselling and not living up to expectations which this exceeds. Glad to have found your channel and now subscribed. Having classified on citizen science projects such as Planet 4 and A1Mars, and now Cloudspotting on MARS it's always good to see martian landscape shots.
I love it when a RU-vid video says “brief” in the title, yet the video is basically a full length feature film. Also, space. This vid is gonna be a 10/10, I can feel it
Hey, small update to your video! Recently today an InSight lander experiment got reviewed and published and showed evidence of liquid water under the surface of mars. Great video!
Just throwing it out there but I would absolutely love to see that Mars Habitat video. No pressure ofc, but so much of the coverage of them is about barely thought out concepts and art projects and so little about the real science and work being done on them. Hell yes I want a video with your level of detail.
Great video, thx for uploading. The lenght is not a problem, there used to be places called cinemas, where they showed full lenght movies in one run and people had no problem sitting trough it (and getting totally ripped off, by paying about 10x too much for popcorn and paying to watch 10minutes of adds). Here i have a pause button. I actually want longer videos, to have more to enjoy. Keep going and have fun!
The more you look into Cassini, the wilder it really was. Imo we haven’t done anything that crazy since. Would be cool to see a Cassini deep dive video.
3 : 24 "Aristotle for instance noticed that Mars would pass behind the moon and therefore must be further away." which is the oldest Eric Dubay pre-debunking I now know of. GreaterSapien just did 134 & 135 which includes another claim of Moon transparency which is impossible if Mars is occulted by the Moon showing it is further away.
It sounds like Mars exploration could benefit from something like a windshield wiper to periodically sweep dust off the solar cells. A number of missions could have been extended by the application of such a device.
I was 23 at the time when Spirit snd Opportunity landed. I was working for the DOJ in my country back then. I started every work day in the office with me opening the NASA website to see the latest updates from those two rovers from the time I was sleeping. I was definitely hooked for years, LOL. Back then, there was no RU-vid, no Facebook, no Twitter.
I think leaving soil sample tubes scattered on the surface was an extremely stupid idea. They should have all been stored on the rover for a simpler single retrieval to a return lander.
I wonder… since dust on solar panels seems to be the main cause of death for various probes… are there any efforts to figure out a system to clean the panels?
In short, it's too expensive and heavy. It's easier to design them to work for a limited lifespan. Or, like more recent rovers, reject panels and use RTGs.
@@gorgonbert I believe NASA has done some preliminary work on using electrical charges to repel dust from solar panels and other systems. Like DKiS said, it's just easier, cheaper and less of a mass penalty to either do nothing, make solar panels slightly more efficient or use an RTG.
I bet, when humans colonize Mars, we're gonna build museums around the Vikings, Spirit, Opportunity, & more. Have it encased in glass, visible from everywhere in the building. Seems only natural given 1) Those are pieces of history & 2) We're sentimental
@@DKiSAerospaceHistory Sorry. I thought it was pretty obvious that it was just a joke at the expense of the opening line of VO, which is a little distorted. But if you actually wanna know; the narration/VO is very loud and distorted at first; it improves, but then there are variations - albeit slight - in the level and the distortion of voiceless alveolar fricatives in the VO throughout. If you're using a compressor on your voice, a higher ratio and slower attack might help (or, use a compressor if you're not); possibly a de-esser; and, to make sure the distance of your mouth from the mic is consistent from one recording session to another. Use your pop filter as a guide. But it could also be an artefact of compression during rendering or from RU-vid's compression. Aside from the few minor audio things, it was a brilliantly made documentary. I enjoyed it immensely. Great work!
