I have to remind you that there were a whole series of robot landers that soft-landed on the Lunar surface well before humans did. The first was the Soviet lander Luna 9, which returned pictures (leading to a bit of a political row between the USSR, which sent the probe, and the UK, which had one of the few receiving stations capable of recovering the returned data, causing the USSR to claim the data was stolen when the UK published the pictures first). This was followed by multiple US Surveyor missions, as well as further Soviet Luna missions that soft landed. It is extremely unlikely that there will ever be any body where humans land that isn't first scouted by robot landers. The information these return about the environment is far to important for risk control of human landings to not get.

@atk05003

9 ай бұрын

The manned lunar landing tends to overshadow those earlier probes in most Americans' minds. (I also forgot about them until reading your comment.) I think part of it is that the US probes were a little less hyped, because they weren't first and because Soviet achievements were (and often still are) ignored or downplayed in the US for political reasons. Another part is that manned missions tend to be more exciting for the average person. It's good to remember that space exploration is hard enough that we don't want to throw things into the complete unknown. We take remote measurements before sending probes and we send automated probes before we send people.

The wording threw me too, but I guess Issac was just using a different definition of a robot explorer, since an immobile listening post/weather station is more 'observing' than 'exploring'.

Isaac surrounds himself with people that love space and that is great! But simply saying space is extremely popular among the general public is not accurate as he does early in this piece. I wish Isaac would do more of a deep dive into the history of space exploration funding as it relates to things like near term colonization and exploration.

A lunar manufacturing facility makes sense. Imagine producing space colony base modules for orbital insertion as an intact colony from lunar orbit, then once complete sending the colony to Mars, Venus, etc. as a finished and fully stocked package. A crew then travels with only that needed for the trip to the colony, to a ready and fully stocked colony facility once the colony is safely in orbit at the destination. This would reduce costs, increase safety, and allow more rapid colonization with larger colony facilities as there would be no issues with launching the entire payload and facility through Earth's atmosphere or gravity well. Instead of a minimally shielded tiny facility the size of a bus for a crew of a half dozen, we could send facilities with everything required to maintain a sustainable colony for up to 100 or more people including heavy radiation / impact shielding and artificial gravity habitats that include agricultural / hydroponics perhaps even manufacturing capabilities. One or more of these colony in box facilities could also be placed in Earth orbit as a very profitable space hotel for the rich, an orbital travel hub once orbital planes become the norm for high speed transcontinental travel, or as a replacement for current science / military stations like we have presently. These could also be tailored to manufacturing micro gravity products, or high G products, for all kinds of applications as well. Though these would likely be more advantageous in locations other than Earth orbit in this case. A lunar facility WILL pay for itself in the long run for those bold enough to risk the upfront capital investment to build it.

Hey Isaac. Could you use a solar system sized "gauss rifle" type of ringed orbitals in a kind of spiral formation to accelerate ships fast enough to make long distance journeys without acceleration being too fast as to harm life on board?

This subject is pure gold : )

I'd like to make a topic recommendation. When discussing solar sails too many people don't understand orbital mechanics and how one transfers between orbits and bodies. They seem to think that solar sails can only be used to accelerate away from the sun, or other source of light, when really they are used to increase, *_OR DECREASE,_* orbital velocity depending on which direction the light is reflected. If the light is reflected forward in the direction of orbital motion the sail will slow down the craft's orbital velocity moving it's orbit inward closer to the sun. Reflected backward it would increase orbital velocity moving it's orbit outward. This is how all movement within a gravity well works until one reaches escape velocity. I think if you could cover this, even if just a short aside within another topic, it would clear up some confusion for many.

1492 to 1776 - almost 300 years - seems like a reasonable estimate for the amount of time before independent nations start emerging from space colonies. The key insight here is that no nation is going to spend a lot of resources building a colony specifically to place beyond their own control. Also, that's only about ten human generations, so the genetic engineering to create viable colonists with zero-gee and radiation tolerance will probably take at least that long to develop into a population big enough for viable long-term colonies.

Clunkier, way more labour intesive as each stamp has to be aligned; but also capable of making better chips since you can mix whatever materials are the best for the application.

We should be at least somewhat better off, considering we've had centuries or millennia of societal and technological development since then. Still, it does paint an interesting, if not odd scene in one's head to imagine a setting akin to the Age of Exploration resting underneath the technological marvels of a 22nd-century human society.

there is no such negative centrifugal force, so it will always add more pressure, mimicking even higher gravity. higher gravity solutions are to put an orbital ring on the world at the location where gravity is equal to earths. An orbital ring works by having a ring made of iron or simular magneticly active material spining at faster then orbal velocities, then use magnetic levitation to support stationary platforms ontop of the ring. So the platforms do not orbit, but the ring does, and all of it experences earth gravity. Of course we have yet to build an orbital ring of any kind so. Who knows how difficult it will be? Not me nor anybody but darn it, if you love your planet you should put a ring on it.

Awsome...as allways

Our biggest problem isn't getting TO another planet...it's safely landing and taking off again and getting all the back that's troublesome

Step one: build an orbital ring, used as a telecommunications hub it should generate trillions in revenue Step two: gold rush, one gold/platinum/iridium rich asteroid would be worth quintillions. This would pay off the ring and much more A mad reckless scramble for gold can move entire civilizations, after that its easy sailing could be an interstellar civilization within a few centuries

Awesome video! However, I think you give EM too much credit. His track record to keep his promises is even worse than NASA. However, however, whatever we do in space we need to work on complete automation of the supply chain on earth.

26:13 Venus also has an abundant Energy source in the form of temperature gradient of its atmosphere.

It's a sad day when you've watched so much SFIA that the you can imagine all of the videos the poll offers.

For clearing space debris, in LEO, grab a chunk, throw it down towards Earth, floating up by that action. In higher orbit, grab a chunk and throw it up, floating down by that action. Repeat.

There should be an Orbital Satellite around the Earth and Moon (With 6 People) and a Moon Base on the Moon (With 24 People). Also too 6 Small Shuttles Spaceships. Plus 2 Land Bases on Earth (With 48 People each). Then go to Mars. After have an Orbital Satellite around Mars and later a Land Base.

Mars could be a major industrial hub for the Outer Solar System, and a stopover point for ships.

I have come to love Isaac Arthurs humor. lol

Has anyone considered life on earth includes a localize field aspect of collective life that will cause life not to function outside that field? We’ve only tested extended human missions in low earth orbit of ISS, very close, and Apollo missions to the moon for a week or so. But what if say human sanity breaks down over time beyond low earth orbit? Testing extended missions near the moon is softer than finding problems half way to Mars with no fuel to turn around quickly.

Awesome. was about to sleep but Now I Ain't. This Look Interesting!

Wonder if a magnetized netting system that can be deployed and controlled remotely would work for gathering debris floating in orbit, then perhaps flown back to ISS for processing or pushed towards earth to burn up in the atmosphere ?! If done a certain way it would be fairly small and the initial module shouldn't weigh much keeping costs down for transport, then every so often have it return to the ISS for upkeep and replacement of the net cartridges ?? Any thoughts ?!

You could build a huge economy between Venus and Mars. Venus has a huge surplus of CO2 and can use it to build an atmosphere on Mars. Freeze it into dry ice and launch it at Mars via orbital massdriver. Just crash them into Mars so it's super cheap a few hundred tons CO2 at a time. It would take centuries but eventually it would be done.

14:54 That's a mine about to be stepped on?

Colonizing the moon first is like colonizing greenland first because it's closer to europe. Mars has all the resources we need for an independent civilization and it's only 6 months away with current technology. Mars is the first step to becoming an interstellar civilization.

Getting places even in our solar system with current technology is going to take months or even years how are we dealing with life support systems for that length of time?

spaceflight re-usability was an issue because those manufacturing spacecraft were incentivized NOT to do it. bringing the per-pound cost of spaceflight was simply bad for business. just as actually delivering any given specific spacecraft was bad for business. additional profits were sustained in overruns, missed deadlines, and failed attempts (for example: the artemis project as a whole until privatization ruined it for politicians and defense contractors). in order to get to space in a way that might fulfill some of the promise of "2001: A Space Odessey" (which was wholly reachable), the entire structure delivering spaceflight needs gross overhauling, as it is the largest hurdle we face...
