The thing is, I'm supposed to be working on an estimate but I got sick of doing math so I came here to relax.
Yeah, link up a dozen or so starships in a giant rotating ring to build a sort of artificial gravity ferris wheel O'Neal cylinder variation. We probably want to send two fully self sufficient space stations like this in order to have redundant life support infrastructure orbiting Mars. Probably set one up orbiting Diemos and the other orbiting Mars. Establishing something of an economy between a Diemos colony, Mars Colony, two space stations, and Earth/Earth’s moon makes a Mars Colony realistic. Just establishing a base on the surface of the moon is so risky. Two redundant space stations for Martian crews to retreat to gives so much more security. In the best case scenario, a simple economy exchanging resources between the surface and orbit would spur innovation and motivate real permanent settlement.

(trying to spread this idea around, since better for it to be in the open than hidden away) One form of immortality does seem increasingly close to being "cracked": the brain-in-a-jar approach. There are artificial hearts, ECMO machines are able to regulate blood oxygen (being used when ventilator doesn't cut it for a COVID-19 patient that has had their lungs damaged/collapsed), and dialysis as artificial kidneys.

@@Xerox-1961 brilliant post. Can’t believe how much/little money has gone into this so far… the point about the F35 illustrates perfectly what Eisenhower was talking about in his farewell address…
A Hohmann transfer orbit doesn’t involve firing the thrusters for most of the trip. You perform a transfer burn from earth orbit, coast until you are close to the moon, then do a capture burn to enter lunar orbit. So while the initial and final burns will take much longer, they’ll still be a fairly small portion of the trip - so maybe an extra day, but the 5 day number will be broadly correct.
from playing around in KSP, the lower power of the new hall effect thrusters shouldn't have to much effect on the time to get to the moon, it will only have an effect on the time it takes to execute the burn.
By definition, that is part of the time it takes to get to the moon. In Apollo, it was the time they began their trans-lunar injection burn until they braked into orbit. With hall-effect, it's the same, except they'd have to execute a dozen such burns at the low point of each orbit.

There was NEVER a lunar orbiting space station proposed until it was realized that the SLS wasn't powerful enough to get the heavy Orion capsule into a low lunar orbit (although the Saturn 5 could get the Apollo capsule and it's lander into LLO). The only experiments you need to do while orbiting the moon is to test different types of radiation protection for 'deep' space and this sure doesn't require a multi-billion dollar space station. As far as Mars goes, no past proposals (dating back to Werner Von Braun) suggested a requirement for a lunar space station. The LOP-G is just a money project to get money to the traditional aero space contractors like Boeing, Lockheed and Northrup Grumman. We should go with something like the earlier proposed European Lunar Village concept.
It is not “just” a pork project. It gives astronauts a place to work in lunar orbit, plus a place to transfer between Orion and HLS. Not only that, but it could be later expanded into a shipyard for building anything from probes to the entire craft that will take a crew to Mars or Venus. Let’s be honest, bigger is better for that trip, and getting something big off of Earth is insanely expensive. Better to mine the materials on Luna and build it in lunar orbit. A Martian HLS or Venusian atmospheric buoyancy craft can be sent up from Earth to rendezvous with the much bigger craft, then be used for landing and ascent.
Its been re-renamed to just "Gateway" now. (Probably good since "LOP-G" is cumbersome.) iHAB and ESPRIT have been co-manifested on SLS Block 1B launches for Artemis IV and V, and Orion will dock them to to Gateway. If the landing itself gets pushed back, the missions will still go to Gateway ensuring no part of the program getting delayed will prevent returning at least to Lunar orbit!
Last I heard they were struggling to keep the mass of iHAB low enough to keep it comanifested on SLS. If the mass goes too high they can likely still launch on another launcher, but then the EUS won't have a good justification on Artemis IV.
@@jamesrwinters Actually B1B had their co-manifested payload situation improve with CDR. The iHab already had a huge mass reduction (to Cygnus diameter) due to fears that the EUS would be cancelled during the Trump administration. But EUS has been fully funded by congress the entire time (ignoring the administration's requests.) Meanwhile the Biden administration has fully supported Block 1B along with Congress. EUS is happening on Artemis IV forwards regardless of payload, metal is already being bent for the first EUS. Block 1B is actually pretty far along. Along with the first test casings for the BOLE boosters for Artemis XIII. (Block 2)

At 4:08 you say orbital velocity is somewhere between 10 and 20 thousand meters per second. I'm not sure where you got those numbers from, but orbital velocity for a low earth circular orbit is about 8000 m/s, and is slower for higher circular orbits. That's for circular orbits. The speed at the low point (perigee) of an elliptical orbit could be higher, but only for the lower parts of the orbit, and would be
so 866sqft is actually very useful once you realize that ceiling height is basically standardized in the USA to about 10 ft so 8660 cubic ft or 245 cubic meters so basically 1/2 of a new york apartment worth of space
Just getting started on the video, but you & the whole team are AMAZING! This is like the 4th video today from the various channels.... and I watch em' ALL !!!
The Lunar gateway sounds like the most complicated way to solve these problems. It sounds like its designed by a commitee who all want a piece of the manufacturing pie. Starship plus crew dragon, job done.
Great video! For the record, LOP-G was just a placeholder name that was used until 2018 or so. Since then it's just been called "Gateway" or the "Deep Space Gateway".
A hohmann transfer will always take roughly the same amount of time once a craft is up to speed and its apoapsis is high enough for it to get caught in the target bodys gravity well if everything is where is it should be in the orbit. The only problem with ion thrusters is their thrust to weight ratio and getting up to that speed may take several burns taking advantage of the oberth effect by burning closer to periapsis but taking time doing orbits in between burns. Or a less efficient big burn while passing periapsis but losing energy burning radail in and out. A low thrust to weight ratio engined craft would also have to start burning retrograde earlier once it reached its target bodys gravity well. The great thing about ion thrusters though is their efficiency and the craft wouldn't have to do a hohmann transfer and could burn for longer picking up more speed as long as it had enough ∆v and could slow down again once it was approaching or in the target body gravity well. Don't let anyone ever tell you video games can't teach you anything all that was learned playing Kerbal Space Program.
Yes, KSP FTW! 🚀 But keep in mind that for human missions to the moon, they'll most likley not go for the standard homann transfer. During Apollo they aimed for a free-return-trajectory, which is quite a bit faster. About three days to the moon, I think.
Yeah, I'd be surprised if they'd do anything but a free return trajectory when they have humans on board. For uncrewed missions, I would assume they'll go for whatever is cheapest, which I assume is whatever requires the least fuel. Not because of the cost of the fuel, but because of the weight. Less fuel = more cargo capacity. Thoughts?
I actually don't know how people on phones can use TH-cam, with all the pre-roll, mid-roll and sponsorship announcements. 100% unusable imo, thank jeebus for Pi-hole and ad blocker.

The Science of Dreams would be an interesting Topic for soon. Why do we dream and more importantly: When is the much-needed Tech discovered that makes you sleep dreamless? Me and others really need it.
$332 million is such an insultingly small budget for something like this. Hell, the US just completed a $10 billion aircraft carrier. God forbid we put that money towards something like NASA.
Just one small problem. NASA hasn't hired enough astronauts to crew both the ISS and Moon missions. Also, when they first started training astronauts for the ISS it took 5 years - an undertaking that now only takes 2 years. In deciding on various timelines for moon missions, they used current ISS training time as a model despite the fact that they should have used the earlier duration as we will again be training new people on new equipment and procedures just like in the early days of the ISS. The normal time to hire crew from the time of the announcement of their missions is 2 years. Add that to the 5 years for the first class of moon bound astronauts and you get 7 years. So the earliest any new hires could be readied for a lunar mission is 2029. And they were concerned about the lunar spacesuits not being ready until 2025. Now a moot point.
"NASA hasn't hired enough astronauts to crew both the ISS and Moon missions...they used current ISS training time as a model despite the fact that they should have used the earlier duration..." This doesn't sound like a problem that NASA has itself, so much as it sounds like a problem that you have with NASA.
@@alexanderstone9463 How is this not a NASA problem? If they don't have enough astronauts to crew both missions one of them will be stalled until there are enough. As for my feelings toward them, I try to call it as I see it. They, like any institution, have good and bad points. This issue seems pretty important to the missions NASA is committed to so their apparent inaction is a valid point to call out.
@Terp My point is that they have not always allowed safety or protocols to get in the way of their deadlines, or rather, those who oversee it haven’t allowed it to. In short, I can imagine them changing the requirements rather than the training, and simply ignoring the old protocols. This might not strike you (or me) as “safe”, but NASA can be a little cavalier at times. As for why they would be so cavalier, it’s simple, they don’t have the money not to be. Because of the ever constant changes in their funding, they repeatedly have to guess about what they’re training their astronauts to do. Faced with this uncertainty I think it’s perfectly realistic to believe that that they will just be like “Eh, what was good enough for the ISS will be good enough for the Lunar Gateway” and then just rewrite the rules to justify this policy.
The musical cue at about 17:08, the start of “Operation and Orbit”: what is it? I know it from somewhere but can’t place it and it’s been driving me crazy every time Simon plays it!
Added context, Hall-effect thruster have the potential for acceleration up to ~30% the speed of light in a vacuum, though currently we can only get between only 10-15% the speed of light with them (theoretically). A Hall-effect thruster is a type of Ion thruster.
Instead of putting the LOP-G in an orbit based on communications needs how about putting some communications satellites into moon orbit? Has that been looked at and were any conclusions drawn?
Great video overall and a good resource for public info on the station Some small errors: -Astronauts do not travel using the ppe -falcon heavy will not transport crew -the station can not be used for mars missions due to its orbit this would take more fuel than departing from Earth
I think this is a good middle-step between Earth and Mars. Better to practice and refine our methods, technology and knowledge on a smaller, closer to home project before sinking the teeth into something MUCH more complicated. Besides, if these are successful and might even find exploitable resources it might help ignite more appetite for a Mars mission.
YES, YES, beautiful really in my limited mathematical comprehension of trigonometry. A famous physicist said some thing about gravity and space time and that one effecting the other in a funny saying he used about how they interact together. I would need to look it up for the precise saying he used.
With Hall effect thrusters you’d likely need to “burn” at perigee to raise your apogee scores of times and have some breathtaking battery capacity. For robotic transfers sure but for manned transfers I highly doubt they’ll use Hall effect thrusters. Likely more for inertial dampening, rcs, and station keeping.
This is all great, but I'm still holding out for taking off in a rocket from Earth and landing it directly on the Moon, Duck Rogers style. But no reverse gear on the rocket engine.
The main purpose of this is to maintain a constant communication with a base at the south pole, which a small, unmanned satellite could do just as well. Manned lunar missions would save fuel by going straight from earth orbit to low lunar orbit, with rendezvous there if necessary. If its a lab to study deep space exposure, just say that. Or whatever it really is.
Excellent. Thank You for great up to date information. Artemis is delayed by technical problems and a hurricane presently. Hopefully a successful and safe launch and mission in the near future.
16% of US total federal spending is on defense. Social Security, federal transfers, Medicare, Medicaid, and other means tested welfare programs make up over 70% of US total federal spending. Also since we now have a space defense force chances are defense spending will go towards some long term space programs.
Now, imagine for a while, that since the end of the Cold War, the ammount of funding for US military and NASA was swapped. We would be living on Mars by now.
Thought: Would you consider making a video on Nauka and Prichal? Two ISS modules which have launched and joined with the ISS since you made your ISS video when you launched the channel.
THANK YOU for calling it by its name: The Canadarm. So rarely do Americans refer to it by its actual name. Invented, developed and created in Canada and named by an elementary student. It’s a point of pride in Canada and it always bothers me seeing American news sources refer to it as “the space arm” or something insultingly generic. So I thank you for calling it by its actual name.
I'm in the states and only ever heard it called the Canadarm. I would be ticked too, hearing media figures call it a space arm, not least because it underscores how airhead influencers ruined engineering in general..
Simon’s disembodied consciousness on a screen, 2,000 years from now, telling our descendants about Earth & hairless apes while they’re on some far-flung planet in the galaxy
Wouldn't it be better to have one ship that specializes in going from the Earth to an Earth-orbiting space station and then have another ship that specializes in going between the Earth space station and the moon (like they did in the movie 2001)? Couldn't you just use the moon as a launching point for interplanetary missions?
It would be more efficient. But don't forget that space is still incredibly dangerous for astronauts. That's why the Orion space craft is engineered to allow a safe return return to the Earth at any point during a mission, just in case something goes wrong. You couldn't do that if you first had to transfer to another vessel.
"Chemical rocket engines are the only engines able to overcome the earth's gravity" Seems Simon isn't familiar with Project Orion "ol' boom boom" the nuclear bomb powered rocket.
damn anti space based nuclear weapon orbiting satellite treaties for stopping us from traversing space with the use of literal nuclear bombs and a big spring
I am generally in favor of not using nuclear bombs on the Earth because of fallout and blast wave concerns, but once already in space this would be an excellent means of propulsion.
Yes and also the nuclear salt water rocket (untested) and nuclear thermal rockets (tested on Earth but never flown: the DRACO project is meant to actually fly one). So there are 3 nuclear rocket designs.
Yeah. Though it isn't emphasized as much as the Moon stuff, realistically Moon wouldn't need LOP-G. However Nasa needs LOP-G and LOP-G needs Moon to get funded... So Moon LOP-G it is. There real job is to put astronauts there to see pretty much "how good or bad humans do in cosmic ray deep space environment". The mentioned in video Deep Space Habitat had an officially listed out *500 day mission* expansion module planned. Since 500 days is the simulated needed flight time for the most common Mars mission concept. So yeah wonder wonder what the LOP-G is about? DSH was way more clear on the nose name about the main job. Guess that is why it didn't stick around.
Yes, yes, the Esprit module... but what about the United Colors of Benetton module? Or the 80s Banana Republic module with safari clothes? Or an Orange Julius module?
I understand that the James Webb Telescope uses chemical thrusters and that they are the main limiting factor on it’s lifespan. I’m sure NASA considered electric thrusters but probably thought they weren’t quite ready yet? Just curious.
Could also have to do with response time. Sure, electric thrusters would have a much greater lifespan, but chemical thrusters can reposition it much quicker.
Bear in mind that simply saying "pints" is problematic as US pints are around 20% smaller than Imperial pints, and the larger Imperian pint is more widely used for things like beer, at least outside the insular US. Same for gallons, naturally.

A Hohmann transfer orbit doesn’t involve firing the thrusters for most of the trip. You perform a transfer burn from earth orbit, coast until you are close to the moon, then do a capture burn to enter lunar orbit. So while the initial and final burns will take much longer, they’ll still be a fairly small portion of the trip - so maybe an extra day, but the 5 day number will be broadly correct.
18:48 most people would point this out as an inaccuracy but since I’m obsessed with COLS, I’m gonna say this is some good foreshadowing from you
from playing around in KSP, the lower power of the new hall effect thrusters shouldn't have to much effect on the time to get to the moon, it will only have an effect on the time it takes to execute the burn.
By definition, that is part of the time it takes to get to the moon. In Apollo, it was the time they began their trans-lunar injection burn until they braked into orbit. With hall-effect, it's the same, except they'd have to execute a dozen such burns at the low point of each orbit.

There was NEVER a lunar orbiting space station proposed until it was realized that the SLS wasn't powerful enough to get the heavy Orion capsule into a low lunar orbit (although the Saturn 5 could get the Apollo capsule and it's lander into LLO). The only experiments you need to do while orbiting the moon is to test different types of radiation protection for 'deep' space and this sure doesn't require a multi-billion dollar space station. As far as Mars goes, no past proposals (dating back to Werner Von Braun) suggested a requirement for a lunar space station. The LOP-G is just a money project to get money to the traditional aero space contractors like Boeing, Lockheed and Northrup Grumman. We should go with something like the earlier proposed European Lunar Village concept.
I would love to get more info on this?
Do you have actual proof?
@@RuralJuror420 proof, sls does not have the physical capability to put orion in LLO nasas own number say so
It is not “just” a pork project.
It gives astronauts a place to work in lunar orbit, plus a place to transfer between Orion and HLS. Not only that, but it could be later expanded into a shipyard for building anything from probes to the entire craft that will take a crew to Mars or Venus. Let’s be honest, bigger is better for that trip, and getting something big off of Earth is insanely expensive. Better to mine the materials on Luna and build it in lunar orbit. A Martian HLS or Venusian atmospheric buoyancy craft can be sent up from Earth to rendezvous with the much bigger craft, then be used for landing and ascent.
Its been re-renamed to just "Gateway" now. (Probably good since "LOP-G" is cumbersome.)
iHAB and ESPRIT have been co-manifested on SLS Block 1B launches for Artemis IV and V, and Orion will dock them to to Gateway. If the landing itself gets pushed back, the missions will still go to Gateway ensuring no part of the program getting delayed will prevent returning at least to Lunar orbit!
Last I heard they were struggling to keep the mass of iHAB low enough to keep it comanifested on SLS. If the mass goes too high they can likely still launch on another launcher, but then the EUS won't have a good justification on Artemis IV.
Well he's clearly just future proofing for when it gets re-re-renamed
@@jamesrwinters Actually B1B had their co-manifested payload situation improve with CDR. The iHab already had a huge mass reduction (to Cygnus diameter) due to fears that the EUS would be cancelled during the Trump administration. But EUS has been fully funded by congress the entire time (ignoring the administration's requests.) Meanwhile the Biden administration has fully supported Block 1B along with Congress.
EUS is happening on Artemis IV forwards regardless of payload, metal is already being bent for the first EUS. Block 1B is actually pretty far along. Along with the first test casings for the BOLE boosters for Artemis XIII. (Block 2)

We don't need a small NRHO space station to make going to mars possible
No mention of how starship is being used as the liner lander? It's honestly hilarious when you compare the size of starship to the gateway
At 4:08 you say orbital velocity is somewhere between 10 and 20 thousand meters per second. I'm not sure where you got those numbers from, but orbital velocity for a low earth circular orbit is about 8000 m/s, and is slower for higher circular orbits. That's for circular orbits. The speed at the low point (perigee) of an elliptical orbit could be higher, but only for the lower parts of the orbit, and would be
Absolutely love when you do space videos! 🚀

The Lunar gateway sounds like the most complicated way to solve these problems. It sounds like its designed by a commitee who all want a piece of the manufacturing pie. Starship plus crew dragon, job done.
Nah. Just Starship.
Great video! For the record, LOP-G was just a placeholder name that was used until 2018 or so. Since then it's just been called "Gateway" or the "Deep Space Gateway".
Science, knowledge and curiosity focused Megaprojects are like cakes they don't come often but god are they good to savor
A hohmann transfer will always take roughly the same amount of time once a craft is up to speed and its apoapsis is high enough for it to get caught in the target bodys gravity well if everything is where is it should be in the orbit.
The only problem with ion thrusters is their thrust to weight ratio and getting up to that speed may take several burns taking advantage of the oberth effect by burning closer to periapsis but taking time doing orbits in between burns.
Or a less efficient big burn while passing periapsis but losing energy burning radail in and out.
A low thrust to weight ratio engined craft would also have to start burning retrograde earlier once it reached its target bodys gravity well.
The great thing about ion thrusters though is their efficiency and the craft wouldn't have to do a hohmann transfer and could burn for longer picking up more speed as long as it had enough ∆v and could slow down again once it was approaching or in the target body gravity well.
Don't let anyone ever tell you video games can't teach you anything all that was learned playing Kerbal Space Program.
Yes, KSP FTW! 🚀
But keep in mind that for human missions to the moon, they'll most likley not go for the standard homann transfer. During Apollo they aimed for a free-return-trajectory, which is quite a bit faster. About three days to the moon, I think.
Yeah, I'd be surprised if they'd do anything but a free return trajectory when they have humans on board. For uncrewed missions, I would assume they'll go for whatever is cheapest, which I assume is whatever requires the least fuel. Not because of the cost of the fuel, but because of the weight. Less fuel = more cargo capacity.
Thoughts?
Two sentences in, and I knew you were a Jeb kinda guy.
He needs a fantasy projects channel covering babylon 5 or ds9 etc...
4:07 no, anything orbiting Earth with a periapsis above the atmosphere at 200km will be going anywhere from 7.8km/s to about 11km/s

Just one small problem. NASA hasn't hired enough astronauts to crew both the ISS and Moon missions. Also, when they first started training astronauts for the ISS it took 5 years - an undertaking that now only takes 2 years. In deciding on various timelines for moon missions, they used current ISS training time as a model despite the fact that they should have used the earlier duration as we will again be training new people on new equipment and procedures just like in the early days of the ISS. The normal time to hire crew from the time of the announcement of their missions is 2 years. Add that to the 5 years for the first class of moon bound astronauts and you get 7 years. So the earliest any new hires could be readied for a lunar mission is 2029. And they were concerned about the lunar spacesuits not being ready until 2025. Now a moot point.
"NASA hasn't hired enough astronauts to crew both the ISS and Moon missions...they used current ISS training time as a model despite the fact that they should have used the earlier duration..." This doesn't sound like a problem that NASA has itself, so much as it sounds like a problem that you have with NASA.
@@alexanderstone9463 How is this not a NASA problem? If they don't have enough astronauts to crew both missions one of them will be stalled until there are enough. As for my feelings toward them, I try to call it as I see it. They, like any institution, have good and bad points. This issue seems pretty important to the missions NASA is committed to so their apparent inaction is a valid point to call out.
@Terp My point is that they have not always allowed safety or protocols to get in the way of their deadlines, or rather, those who oversee it haven’t allowed it to. In short, I can imagine them changing the requirements rather than the training, and simply ignoring the old protocols. This might not strike you (or me) as “safe”, but NASA can be a little cavalier at times.
As for why they would be so cavalier, it’s simple, they don’t have the money not to be. Because of the ever constant changes in their funding, they repeatedly have to guess about what they’re training their astronauts to do. Faced with this uncertainty I think it’s perfectly realistic to believe that that they will just be like “Eh, what was good enough for the ISS will be good enough for the Lunar Gateway” and then just rewrite the rules to justify this policy.
Maybe do an episode on "fragging" that occurred during the Vietnam War.

Added context, Hall-effect thruster have the potential for acceleration up to ~30% the speed of light in a vacuum, though currently we can only get between only 10-15% the speed of light with them (theoretically). A Hall-effect thruster is a type of Ion thruster.

Only to find out Moon cheese tastes just like cheddar, with just perhaps a touch of wendslidale.
Instead of putting the LOP-G in an orbit based on communications needs how about putting some communications satellites into moon orbit? Has that been looked at and were any conclusions drawn?
Yes, I believe China is doing it…
Great video overall and a good resource for public info on the station
Some small errors:
-Astronauts do not travel using the ppe
-falcon heavy will not transport crew
-the station can not be used for mars missions due to its orbit this would take more fuel than departing from Earth
I think this is a good middle-step between Earth and Mars. Better to practice and refine our methods, technology and knowledge on a smaller, closer to home project before sinking the teeth into something MUCH more complicated.
Besides, if these are successful and might even find exploitable resources it might help ignite more appetite for a Mars mission.
The cannonball actually never "turns." It actually travels in a straight line. It's the space around the mass it's orbiting that's curved.
Its all relative
YES, YES, beautiful really in my limited mathematical comprehension of trigonometry. A famous physicist said some thing about gravity and space time and that one effecting the other in a funny saying he used about how they interact together. I would need to look it up for the precise saying he used.
With Hall effect thrusters you’d likely need to “burn” at perigee to raise your apogee scores of times and have some breathtaking battery capacity. For robotic transfers sure but for manned transfers I highly doubt they’ll use Hall effect thrusters. Likely more for inertial dampening, rcs, and station keeping.
This is all great, but I'm still holding out for taking off in a rocket from Earth and landing it directly on the Moon, Duck Rogers style. But no reverse gear on the rocket engine.

"The power of a rocket engine, in the palm of my hand"
The main purpose of this is to maintain a constant communication with a base at the south pole, which a small, unmanned satellite could do just as well. Manned lunar missions would save fuel by going straight from earth orbit to low lunar orbit, with rendezvous there if necessary. If its a lab to study deep space exposure, just say that. Or whatever it really is.
Excellent. Thank You for great up to date information. Artemis is delayed by technical problems and a hurricane presently. Hopefully a successful and safe launch and mission in the near future.
330 million? It would cost more than that just to get all the components launched
16% of US total federal spending is on defense. Social Security, federal transfers, Medicare, Medicaid, and other means tested welfare programs make up over 70% of US total federal spending. Also since we now have a space defense force chances are defense spending will go towards some long term space programs.
Now, imagine for a while, that since the end of the Cold War, the ammount of funding for US military and NASA was swapped. We would be living on Mars by now.

THANK YOU for calling it by its name: The Canadarm. So rarely do Americans refer to it by its actual name. Invented, developed and created in Canada and named by an elementary student.

So I thank you for calling it by its actual name.
I'm in the states and only ever heard it called the Canadarm. I would be ticked too, hearing media figures call it a space arm, not least because it underscores how airhead influencers ruined engineering in general..

VIDEO STARTS AROUND 7:12
Wouldn't it be better to have one ship that specializes in going from the Earth to an Earth-orbiting space station and then have another ship that specializes in going between the Earth space station and the moon (like they did in the movie 2001)? Couldn't you just use the moon as a launching point for interplanetary missions?
It would be more efficient. But don't forget that space is still incredibly dangerous for astronauts. That's why the Orion space craft is engineered to allow a safe return return to the Earth at any point during a mission, just in case something goes wrong. You couldn't do that if you first had to transfer to another vessel.
Really good video Simon! Inspirational!

damn anti space based nuclear weapon orbiting satellite treaties for stopping us from traversing space with the use of literal nuclear bombs and a big spring
I am generally in favor of not using nuclear bombs on the Earth because of fallout and blast wave concerns, but once already in space this would be an excellent means of propulsion.
Pretty sure it's a bad idea to launch things from earth using nukes. Also, can you actually call a bomb an 'engine'?
Yes and also the nuclear salt water rocket (untested) and nuclear thermal rockets (tested on Earth but never flown: the DRACO project is meant to actually fly one). So there are 3 nuclear rocket designs.

Your comparisons are NOT pointsless. They make sense.
I would like an inflatable habitat added to the LOP-G.
The LOP-G is also a test spaceship for trips to Mars and back.
Yeah. Though it isn't emphasized as much as the Moon stuff, realistically Moon wouldn't need LOP-G. However Nasa needs LOP-G and LOP-G needs Moon to get funded... So Moon LOP-G it is. There real job is to put astronauts there to see pretty much "how good or bad humans do in cosmic ray deep space environment".
The mentioned in video Deep Space Habitat had an officially listed out *500 day mission* expansion module planned. Since 500 days is the simulated needed flight time for the most common Mars mission concept. So yeah wonder wonder what the LOP-G is about?
DSH was way more clear on the nose name about the main job. Guess that is why it didn't stick around.

If I ever get into Congress, I'm going to vote for a 100 billion dollar funding boost to NASA.
I understand that the James Webb Telescope uses chemical thrusters and that they are the main limiting factor on it’s lifespan. I’m sure NASA considered electric thrusters but probably thought they weren’t quite ready yet? Just curious.
Could also have to do with response time. Sure, electric thrusters would have a much greater lifespan, but chemical thrusters can reposition it much quicker.

Bear in mind that simply saying "pints" is problematic as US pints are around 20% smaller than Imperial pints, and the larger Imperian pint is more widely used for things like beer, at least outside the insular US. Same for gallons, naturally.
