[@ultrajd]

I was 10 years old when the ISS construction began. Ironically, I was also in my current events class and we watched the launch of the first American module unity on TV. One thing, though that I recently have discovered is, we’ve discovered new ways to generate energy through the use of heat. Now I’m sure they’re already working on this but instead of just taking the majority of the waste heat from the station and radiating it out into space why not try and find a way to use it to Produce more energy? I mean yes, as stated in the thing, the station creates more than enough energy through its solar panels, but I would think that it would be a good idea to try to make something that could use that heat purely because of the fact that, obviously you would want to probably have as many redundancies as you can. The same thing could be said, for the hydrogen that is created through the electrolysis. I’m sure the hydrogen could be used either as a energy source or better yet perhaps use it as a form of thruster fuel. I’m sure all of this is far easier said than done. But , you know just figured I’d put in my two cents.

Or maybe packing more dirt on the moon could turn down the temp a notch or so

Since SpaceX began flying the Falcon 9 rocket in 2009, the cost of launch per pound has decreased from $10,000 per kilogram to roughly $2,500. Starship promises to lower the cost of launch even further.

[@korana6308]

[@ginamiller269]

[@stephenskinner4857]

I was part of the original design team. It was way more pound per launch than what you stated. It was $11,000 per pound. Converting kilograms of 2.2/ 1 = an aprox. cost of slightly under $4600/pound. It was way more than that. The project went over budget that drove 3 iterations and eventually more international partners to make happen. That's whyy the final design was named the International Space Station. - Stephen Skinner

[@craig620]

They covered two topics that I thought deserved better explanations. #1 Round versus square hatches. I'm sure each country had good reasons for their design choice. What are the pro's and con's of each design? #2 They spoke at length at how expensive it is to ship oxygen for breathing to the station. Then... lets extract the Oxygen out of H2O. Is there a water fountain in space that negates the shipping cost for water? Each pound of anything costs the same to ship, regardless of it being steel, aluminum, water or air. What factors are involved that give the oxygen extraction from water process the advantage?

[@korana6308]

My exact thoughts as well on #1, perhaps it was a deliberate design change as to not be compatible with each other. You'd be surprised how many thing were deliberately done differently just to be different.

[@Tallorian]

I can only speculate that round hatch and/or docking module better fits spherical capsules (also, more resilient structurally), which is how Soviet ships were from the dawn of space program; that's why it could have become a tradition (Soviet program included a lot of space docking and multiple space stations). Square hatch is likely more comfortable to pass through in a spacesuit, and Shuttles mostly needed hatches for spacewalks instead of docking, and they weren't supposed to undergo a lot of strain during return. Perhaps that's why it became the standard. Remember that Apollo program had a lot of docking involved during the missions, and its docking system was round at that time - probably for the same reason as Soviet capsules.

[@AerialWaviator]

This video appears to be almost 10 years old (guessing from ~2016). As of 2024, the ISS only have 5-6 more years of useful life remaining. By 2028 new (commercial) space stations will begin to take over its purpose in LEO. NOTE: just about every rocket shown in this video has been retired and replaced by newer more advanced launch vehicles. The cool thing is the cost of lifting mass to LEO has dropped from $10,000 in 1998 to under $1000 in 2024. Within a few years the new Starship booster will be able to launch structures the size of ISS in just a couple of launches, not the more than 20 SpaceShuttle launches required for ISS. Comparing ISS launched pre-2000 to Tiangong space station launch in 2021 shows how far human space flight has come. All the wires and cabling seen on ISS does not exist on Tiangong, as computers now use wireless technologies. Hard to believe that ISS was launched at the dawn of the internet age. What replaces ISS in 2030's will be even more amazing. Multiple commercial space stations are planned and currently under development.

They expel the hydrogen as a waste product after separating it from the oxygen in water. Why can't they use that expelled as a way to make adjustments to move the ISS? Maybe they do, but consider it less than a reason to explain it?

[@karstentopp]

To burn hydrogen, you need to compress it. Compressing hydrogen is hard. Compressor equipment is heavy. And, most importantly, to burn hydrogen, you need oxygen.... No, hydrogen is just waste.

[@TThoMusic]

@@karstentopp That's true but who said anything about burning hydrogen? Even without combusting it you could still use it as a propulsive gas.

[@karstentopp]

@@TThoMusic No. The impulse wold be ridicuoulsly small. To get anything remotely useful, you would need a heavy gas - not Hydrtogen, which is incredibly light - and at high pressure, whioch you will not have without a heavy compressor and a very heavy pressure tank. Rockets get by this by cooling Hydrogen until it is liquid and then use this high pressure liquid Hydrogen to burnit with liquid Oxygen. Liquifying H2 is energy intensive (and did I mention.. heavy?), something you don't have onboard ISS. Sorry, that H2 is just waste. Oh, and did I mention, that you need a bloody lot of hydrogen and oxygen to do useful things. The main tank for the shuttle was all storage for liquid H2 and O2 ...

[@Gt92279]

How do they continue to get oxygen? Wouldnt they run out of water?

[@karstentopp]

@@Gt92279 the ISS is reusing the air. They bind CO2 chemically and they only have to replace the actual used oxygen. Water is a waste in many processes and when you split H2O into H2 and O2, you minimise the waste, too. But humans not only … erm … urinate, they also exhale a lot of water.
