Falcon heavy made it.

well elon chouldnt find a head for his rocket department as no one wanted to take the risk so he got educated and headed it him self, he put in alot of work himself

and to me he is greatest earth hero cause he is making our survival clearer and more realiable

it choulda been bill gates or a few other but it was musk

plus earth is doomed only in space will human reach our true future

in space, enviroments can be closely controled leading to longer safer life with out pollution in air and alot of natural disasters

humans will evole under these conditions

say we heading to planet 1000 years away we can slowly change eviroment to match evolving and adapting along the way where on earth we evolve for earth only in space will we become more powerfull then you can imagine (if we manage a good gravity system)

so the sooner we get on it the better where others lack musk steps up lol -realizes he is elon fan boy- -looks into others attempting space- yea no one can compare

I think that most that we can do is travel inside our own solar system. Everything else is just way too far away.
Going to Mars has 0 benefit because they would still be heavily dependant on suppllies and stuff from earth. Most realistic and useful thing is probably mining asteroids that are close to us.

[viznew]

to make it outside our solar system whould take a ton of work yes

plain ole ship, no wont make it (unless its massive)

but hollowed out astroids sent in huge packs as generational starships chould work (this heres is my familys rock for 14 generations)

but we need exposer to the space living conditions as soon as we can if we ever hope to adapt to survive those conditions

astronaughts should be rockstars touted around getting laid having babys from genes exposed to space

once earth is seen as 100% doomed or war/ disaster strikes there will be explorers that will rise to the challenge its human nature

Saturn's moon Titan might eventually be used as a source of fuel, since it's entirely covered with hydrocarbons. Some of the ice moons like Europa will probably be used for their resources, too.

The closer planets are more or less useless, Mercury for it's intense solar radiation and Venus due to the natural runaway greenhouse effect. If someone ever worked out a way of surviving the extreme conditions on Venus it might be useful, since it's believed to contain many of the same metals as Earth.

The gas giants are practical and solar bodies beyond that are much to far away.

The only things that I can see happening in space exploration in my lifetime are a moon base, asteroid mining and visiting Mars.

You know that all this environmental control is actually harder on the human body than living on this disease ridden planet, yes? Mammalian life is extremely complex and we rely on a lot of the "bad stuff" we run into during life to actually be healthier. They're finding a variety of viruses are actually inoculating the body against some of the stranger forms of cancer. We're just barely touching on the wild, varied needs of a healthy bio-culture in the body (mostly the gut).

Let's not forget that space itself is an extremely unhealthy environment. We still haven't figured out how to mitigate the effects of long term space living. The folks that are out there for more than a few months have to go through very vigorous rehab when they return to Earth.

We're a long way from making space safe and practical. The only way it's going to happen is if we can figure out a way to make the Alcubierre drive or something like it work. Otherwise we're stuck to Earth and Mars, maybe Venus if we can figure out a way to make that oven habitable. (Some have mentioned seeding it with algaes and organisms that are found around volcanic vents and such that could withstand the extreme environment.)

i see your point space is danger zone, and we eventually will prob master keeping humans alive in artifical eviroment (biodome taught us something) but if we set goals and over time prep for a very long cross galaxy trip, we chould and hopefully will escape the suns pull

picture massive astroid of heavy metal hollowed out with a rotateing rings spinning (artifical grav/ control/ magnetic feild generator) inside is where human spend most thier time
around this main astroid is 50-10 small astroids in formation every one heavy metals (with some prob huge ships and stratigic movement can steer the group if needed by moveing the small astroids and allow gravity to pull the main rock/ sling shot around other bodys in space, aslo can postion them in the path of something harmfull to block radiation or something till pass)

most the time little outside activy to conserve fuel

with a large number of these units and teamwork i think possiable, we may just sail past viable worlds collecting thier space junk and other rocks to substain us (resource are easier to locate in space)

if we control enough of these we chould in theory steer rouge plants and eventually just ride a couple of planets around the galaxy sling shoting them where ever we want

lol and i think iv gone into sci fi here lol just trying to convince myself its possable prob (video game idea thou its prob been done)

I think that there are only two major issus that affect human body when living in space for long term. Radiation and weightlessness.
There is a lot of various radiation in space, coming form the sun and what not. Perfectly filtering this out is a bit difficult.
Weightlessness could have a lot of very long term effects that we dont yet know, but the major issue is that without gravity of the earth, you lose lot of force in your muscles, because they dont have to support your own bodyweight. If you never plan to return to earth, this should not be an issue. What would happen to baby in that environment, would it grow to become normal even without the gravity of the earth, there is only one way to find out for sure.

Of course theres a ton of other issues. What if something gets broken? It might be impossible to repair without getting materials/things made with infrastructure that can only be built on earth, because it requires a lot of space and weighs a lot. Probability of being hit by some small flying thing increase the longer you would spend time in space, it could make a big hole in the wall or cause erosion, causing effects to the spacecraft on long term.

maybe Venus if we can figure out a way to make that oven habitable. (Some have mentioned seeding it with algaes and organisms that are found around volcanic vents and such that could withstand the extreme environment.)

Just throwing some organic things there wont make it habitable. For earth, it took billions of years to evolve from first cells to atmosphere with enough oxygen for the life on ground to even start developing.
Turning some planets that dont have oxygenous atmosphere into planets with suitable atmospheres for human life, thats a big big long long time project.

The two big issues we face in near earth orbit are solar flares and weightlessness. The first can penetrate the Van Allen belts that protect the Earth from cosmic radiation that would destroy all life. Otherwise, we can shield astronauts for short periods of time well enough from such things by building s a safe area on any ship.

Weightlessness is the big one. Long term weightlessness causes muscle and bone loss and joint issues. Current programs help mitigate it for anyone living aboard the ISS under 3 or 4 months, but those that stay there more than 6, IIRC, need to do rehab for at least a few months upon return to Earth.

Another thing I didn't mention: if we end up with permanent colonies on the lunar surface or Mars, anyone born there will likely be stuck there until they're old enough to go through very intense physical training due to the variance in gravity. This is an area of physiology we just don't know yet. Let's not even think about being born in space, even with artificial gravity. (Check out Wall-E if you haven't seen it. Simplified for the audience, but more or less accurate, and a fun show to watch about the nature of life and intelligence.)

But what if one was not planning to return to earth?
Somebody who would live his whole life in space, in weightlessness.
You would not need those muscles in that case.

It's not just muscle deterioration. The human body is not designed to live in zero gravity. Fluids build up in the eyes, blood doesn't flow properly, the heart can weaken and even the digestive system can mess up without gravity to help it. Unless people can find a way to fix the zero g problem, we aren't going anywhere fast.
