I made it to 64… that was after many motocross wrecks, knocked out surfing, free style rock climbing disasters, 272 skydiving jumps, falling from a mountain in 1996 on a remote hiking trip, numerous being thrown, knocked off and various mishaps on horses… and no… I never learned when to stop. My body finally said “enough” and in 2020 I was in the hospital diagnosed with heart failure and put on a heart transplant list… fast forward to 2024 and I was taken off the transplant list and told by my cardio team… “we have no idea, how your heart repaired itself”… the future and journey ahead has just as many risks as before… but we survive from struggle and gain strength from what we learn… I never liked living “inside of the lines” although humbled these past few years… I would fly on Polaris Dawn in a minute
For the people worried about risk, they are blessed to live in a world where they feel safe. For some people though, risk is just part of the environment you are in to accomplish your goals. I didn’t think I’d live past my 20’s. The rest is just extra.
@@TheScottShepard I agree with you. We (myself included) tend to take what we have for granted. I try not to any longer… we are not guaranteed tomorrow
It is risky, yes, but so is a lot of what we do in life. We wouldn't be in space in the first place if we didn't take these risks, so I don't see this as too much of a problem. I will, of course, be hoping that everything functions correctly and that the crew will indeed return safely.
It is crazy that the gemini astronauts that did space walks in the early 60s is perfectly normal but the spaceX EVA is the biggest deal in the world. Anyways, I loved the video.
10:33 I was also a bit worried for the spacesuit, because "vacuum" is scary thing, but then I listened to the interview and they mentioned they literally already walked inside a vacuum chamber. I wondered about that a lot and I was sure they wouldn't risk that, but they did, so they're as prepared as you can be.
There also may be legal constraints on NASA accepting Jared Issacson's generous offer to repair the Hubble Space Telescope. Generally, federal law prohibits the Government agencies from accepting voluntary services. But I would love to see the Hubble repaired and upgraded. This looks like a risky and interesting mission. Thank you for the detailed preview. Best wishes to the crew. I am enjoying your videos here and your posts on Threads, Swapna.
Apollo 9 was only with a crew of 3. A few months before that was the Soyuz 5-to-4 crew transfer. After attaching in orbit both Soyuz 4 & 5 were depressurized. The pilots for each stayed in place while 2 crew spacewalked from 5 to 4. Both the capsules were repressurized and returned separately.
Swapna, at about 06:12 in this video... *_"Space is inherently risky because it is actively always trying to kill you."_* _Space_ is like _Australia,_ minus all the unique animals...😉
Humans have always performed risky things to advance knowledge. As long as all the participants know every risk and have a voice going forward when something that wasn't predicted happens, then that's really up to them. No one on the ground should really have the final say, only those with their lives on the line can make those final choices. Unanimous or abort, the only choice between that crew.
An excellent video! Perhaps because NASA has become so risk-averse, we need missions like this to test new technology and procedures. I'm sure NASA will eventually use the new SpaceX EVA suits, the Skywalker adapter, Starlink laser communications, etc, but their internal procedures make it difficult to allow this until the things have been properly tested. Almost a Catch-22, but this is where private missions like this break the deadlock. If the final Polaris mission succeeds this will surely accelerate Starship's crew certification process.
@@GordonSturrock I'm not saying that NASA's risk-aversion is bad, but at some point someone does need to take risks to move things forward and this is where missions like Polaris Dawn come in. I see the Polaris program as a logical extension to NASA's desire to delegate development work to commercial entities. NASA will integrate new technology once it's been properly tested, either under the umbrella of fixed-price contracts or as free submissions from companies and private individuals performing missions like this. It's actually a good delegation strategy that's working because of the growth in commercial opportunities in space.
@@victorkrawchuk9141 always chasing "technology". Isn't that what's killing us, or perhaps you haven't found out yet, that almost all of us will be dead soon?
Enjoyed hearing the detailed rundown of the risks! Personally, I am going to be the most worried about the suits (never tested in space) and whether the craft can re-pressurize ok. But, it's an exciting mission for sure!
Well done! This was quite good in discussing some of the details.about the mission that are directly relevant to risk-informed decision making in space medicine and human spaceflight more generally, Toward the end, it also nicely reviewed a wide range of practices that have been utilized in preparation for human spaceflight, both as analog environments for training and as sources of evidence about hazards and associated risk.Thank you for distilling complex scientific, technical, and operational content into plain language and an educationally effective presentation. For one of your next videos on Polaris Dawn, I personally would be interesting in hearing a bit more about the characteristics of the radiation environment at that altitude that are different from exposures in prior missions. Also, what are plausible design reference missions to which such difference are relevant? Thanks again.
I think in 10-20 years there will be more private citizens in space than professionals. So it makes sense that going forward LEO firsts will mostly be from those private citizens. I would absolutely volunteer for something risky to potentially move space flight forward. If the other Jared wants to hit me up, I science well. I'm excited to see the rest of the Polaris flights and to see what they get into testing. I'm especially excited to see the first crewed Starship flight.
Since there are plans for repetitive and long term space missions This is a place for building reliability All we need to have one crew coming up dead to sober people up
Great content, presentation, very informative Swapna. On what data did SpaceX rely on to determine that the Van Allen belt radiation exposure risk is acceptable?
The Eva SpaceX suit will always be connected to the spacecraft life support for this mission which is the white umbilical cord shown in an earlier trailer for this mission.
Great Video ! You speak Latin ? Does the HLS have an Air Lock ? Also does the HLS also have a LIDS Docking Port ? The Tech developed to return to the moon to stay, can take US and the world to Mars and beyond ! tjl
SpaceX spacesute work on lower psi than NASA spacesuit. Azote in the bloodstream must be cleared for 2 hours before venting.... Would be interested to understand the wall process
It will ultimately be interesting to learn if humans can live extra long in space or on Mars without having the Earth’s microbiome along. It seems that we not only have our own individual and unique microbiomes but constantly interact and exchange microbes with our environment as we move through it. This won’t be available on Mars. What might be the long term health effects?
I’m very curious about this as well. And we know about low Earth orbit but what about further out, with less (or no) protection from Earth’s magnetosphere? We have to figure it out
I saw another channel refer to the main astronaut of the mission as a thrill seeker, that is a dangerous place to have his mind for this. Apollo was all military who are trained to do it precisely a certain way but be ready to react to whatever happens. A thrill seeker will risk doing things that might end very badly without knowing how to deal with the repercussions. It may all work fine because they are not the first to do it, but they are using new equipment, so I am a bit nervous.
Yeh, its pretty risky, I’m not sure it’s too risky, modifications and unknowns, hopefully they make sure every system works before Polaris Dawn, if there is a leek, they can pressure again quickly, if that system works, so that is critical.
They are professionals and have done risk analysis. Same as racing cars on a track or scuba diving. There is new knowledge to be gained and I for one applaud Jarrod and colleagues for this mission which is end to end well examined for risk from everything Jarrod and SpaceX have documented.
Good explanations....I think it would have been much more relevant for this mission to go to the Hubble space telescope and to repair it...Just floating in space has no purpose...
Fam. So they supposed to go and try to fix Hubble when they don’t even know if the EVA works properly? You do realize that this mission HAS to come before that kind of mission right? Dragon also needs a robotic arm which it doesn’t have to my knowledge.
@@maniacslap1623 Yes..Perhaps Hubble only needs some small parts to be replaced with no need of a robotic arms. They will see if a Polaris 2 mission can be useful. NASA should have developped an improved Shuttle ( smaller, with falcon 9 design recoverable boosters, better tiles, best H2 tank insulation, etc...) instead of wasting money with a Starliner
I am curious why Elon Musk himself has not flown in to space. If I were him I would want to at least fly once just to experience weightlessness and the incredible views of the Earth. Jeff Bezos and Richard Branson both flew on very short flight just barely above the Karman line of 62 miles in altitude. So why hasn't Elon Musk flown at least one time as he's such as space "guru?"
Yes!! Through the lowest part of the Van Allen belts, what’s called the South Atlantic anomaly-which fun fact might be caused by pieces of another planet buried deep in the Earth’s mantle
You said that the thing you were most interested in was artificial gravity, well so am I, but you say nothing else about it! What kind if test or experiment are you referring to? How will they experiment and how will they go about this! Are just going to spin the capsule around? That is not going to work. Are they going to use a tether , abut a quarter of a mile long each way? You didn't tell us anything about it! It is the most important task of this whole flight and there is nothing about it! If they are just going to spin the capsule around, that will not prove or reveal anything! IT seems, according to y=the video or comments, that no one else has any interest in the test of artificial gravity! I'm pretty sure, what ever the test or experiments! Where is there more information abut this?
Why be glad that your tax dollars don't go to space exploration and research? If I could guarantee that my tax dollars all went to just that, I'd happily pay tax! What a weird comment from that person, though...
Not only is it risky (kind of), but it has no purpose. This is a vanity project by Isaacman. None of the stated goals of this mission requires humans. I'm getting tired of billionaires.
They have been practicing this like crazy for 2 years, with some of the best engineers on the planet backing them up. Jared Isaacman, Scott Poteet, Anna Menon, & Sarah Gillis are a kick ass crew. Since they are so experienced I believe they are doing all the Polaris missions including test flying the Starship. Jared even told NASA that he would fix the Hubble Space telescope on his dime, not the taxpayers but NASA like usual choked. If humans were adverse to risks, we would still be living in caves.
If the hatch fails to seal after the spacewalk is complete, we have four dead people. I think the rest is manageable. There is nothing to be learned on this flight which couldn't be postponed until there was a better way to egress the capsule in a vacuum. Reminds me of a tourist submarine that died a year ago, because the owner and financier, who was onboard, had a giant ego. Space is no place for egos. A small orbiting lab vessel they could dock with, equipped with a double airlock and extra air could have been built and sent up on an accompanying rocket. Plus, it could have been re-usable, so Polaris could perform more flights. The biggest thing we will learn from this one is whether or not four people can survive the opening and closing of the hatch in a vacuum.
It’s risky driving on the road…if we didn’t take risk we’d still be in the trees in the African savanna worrying about finding fruit and avoiding snakes…and other primates…life without risk isn’t worth living
You sound kind of pessimistic. Since the beginning of Space exploration risk is always present and has been in many other human endeavors. But how we learn, how we make progress? By taking risks and learning. That’s how humanity has reached the present status of civilization.
Fear mongering about space isn't cool. Yes of course there are risks, but someone hyping the risks isn't helpful. I'm blocking your channel and hope others do as well. No one needs this type of content.
Yes, this mission is risky. Extremely risky. It is a "thrill seeker" mission, not much different from the OceanGate Titan disaster. If someone wants to risk their life, and possibly kill themselves doing something stupid, that is their right. I am 65, and have done a lot of stupid things in my life. I am now seriously disabled, I have extensive joint and connective tissue damage, have a serious loss of mobility, and am in constant pain. I am also diabetic and have stage 3 kidney disease. Do I regret doing all the dumb things I have done? For the most part, yes. I could still have had a lot of fun without doing nearly so much damage to myself. Yes, some risks are worth it. But taking extreme risks just for recreational purposes is just plain STUPID. If I were SpaceX, I would not be participating in it. If someone dies, SpaceX will likely be blamed. And given the situation with the POS Boeing Starliner, and the fact that we now have two astronauts stuck on the ISS for another 6 months, I think this mission should be scrapped, and instead used to bring those astronauts home.
