For over fifty years, man has been yeeting himself and his devices into the aether. After the first satellite was launched, The United States of America and Union of Soviet Socialist Republics had a decade long dick measuring contest which culminated in the USA landing two straight, white, cisgender males on the moon. Since this event is generally considered the greatest ever achievement of mankind, people thought "Well, can't top that. Might as well stop trying." And so the zeal for space exploration died down...That is, until today!

Welcome to the new space race! Enthusiasm for outer space hasn't been this high in decades, and this time instead of just superpowers, It's also billionaires who are trying to one up each other to get to the final frontier.

The players:

The National Aeronautics and Space Administration is the United States' agency responsible for their space program. As of the time of this writing, it's administered by Bill Nelson, A former astronaut and Senator. Until recently, NASA did most of the heavy lifting earlier in history that paved the way for what is currently being done in the US, so even though they may be expensive, slow, and inefficient, they at least deserve some credit for getting things off the ground. They are building a heavy lift rocket called the Space Launch System, or SLS, which will cost around $2,000,000,000 per launch, and will put people on the moon again, even though they already did that.

SpaceX is the space exploration company of Elon Musk, who wants to colonize Mars because he has run out of stuff to do on Earth. They are building a heavy lift rocket called Starship, which will be totally reusable and will (supposedly) reduce the cost per pound to orbit substantially. It will be the biggest rocket ever flown. SpaceX already has had success with a partially reusable rocket, the Falcon 9.

Virgin Galactic and Virgin Orbit belong to Sir Richard Branson, that guy that kinda looks like your uncle. Galactic has a rocket plane that can take people into space (debatably, since not everyone agrees how high up space starts) but can't go into orbit. Orbit launches small rockets into orbit off of an airplane.

Blue Origin is a company owned by Jeff Bezos, CEO of Amazon, the company that wants to enslave mankind. Blue Origin has rocket called New Glenn that goes straight up and down, but can't get to orbit. They are planning the build two other rockets: New Shepard and New Armstrong, both heavy lift rockets, but we haven't seen much of them. They are developing their BE-4 engines for use by themselves and for United Launch Alliance, but they are late, and ULA CEO Tory Bruno wants his engines NOW!

Of course there are others, such as Roscosmos, JAXA, ULA, and more, but if I covered every government agency and contractor, this would go on forever. This op is mainly meant to cover the eccentric billionaires who fight each other on twitter. Add more as you see fit, and discuss any space flight news, launches, history, and technology.
 
media sperging about the billionaire space race is gay. musk has already won and he's going to save humanity whether they like it or not. there is not a single cause more important than making humanity interplanetary, interstellar, intergalactic, and interdimensional, in no specific order.
 
It sucks that space travel seems to have regressed. It also sucks just how hard space travel seems to be.

If "flying saucers" - "reactionless drives" - actually worked, getting into space would be much cheaper. A ship could just float up into space with a steady supply of power, or even use some material like "cavorite" to defy gravity. But in real life, reactionless drives appear to be BS, so the only way to get into space without space elevators is with fast-burning rockets. Annoying stuff like "delta-V" and "specific impulse" are things, and every gram counts.

And then once one gets into space, FTL doesn't seem to work, as "Heim theory" (hyperdrive and hyperspace) seem to have been disproven, and "warp drive" (Alcubierre drive) seem to have issues that make it impossible to use. So we seem to be stuck with slower-than-light travel, which has serious problems unless the ones doing the interstellar travel are some kind of machine. Even manned interplanetary travel is hard, what with travel time at slower-than-light, physiological limits and hazards like radiation and hostile environments.

tl;dr: It seems we're stuck on this dumpster fire loony bin of a planet until we die, unlike in fiction where space travel is easy.

We won't be able to go to the stars until we shoot all the joggers into the sun. We went from first airplane to walking on the moon in 60 years. Then all the civil rights nonsense started and we've made no meaningful gains except litter our orbit with satellites.
 
Nuclear technology has the answer again! or at least an answer. CRISPR will eventually help harden our worthless meatbags against radiation, and perhaps greatly expand our lives. whether that's solved before we can just upload ourselves, who can say. i'm personally in favor of a nanomachine virus that slowly replaces your meat brain with electronics over time. interplanetary travel is easy with orion drives, and fast interplanetary travel is possible with nuclear salt water rockets. interstellar (to a few close stars) is even possible within a human lifetime with NSWR. certainly these both have their issues. but they are infinitely more solvable than the massive amounts of energy and negative matter though to be required to create Alcubierre warp drives and wormholes. they are also both extremely difficult to develop safely on earth. with space infrastructure powered by starship, it can safely be developed on the moon... or mars... or mars' moons... take your pick. don't be a nasty liberal and get scared of a little nuclear detonation.

one of the very interesting potentials of starship is in disposable probes. that might sound like it runs contrary to the purpose, but a cut down starship is actually cheaper compared to the typical total cost of a deep space probe mission on disposable rockets. if you aren't planning on landing at all, or if you're landing on a body without an atmosphere, or with an atmosphere that's too thin to do a belly flop, you can remove the atmosphere optimized engines. you can also remove the small header tanks that they use during the flop. you can fit so much science in that bad boy. and save on engineering costs trying to shave off every gram and compact every instrument to fit in restrictive fairings on other rockets. hell, starship is so big, you can fit a few other, smaller, orbital capable rockets in it, like the rocket lab electron. imagine, if you would, a starship mothership, that goes to saturn, or jupiter, and it's just chock full of probes and landers to go explore all the major moons. wow
 
a nanomachine virus that slowly replaces your meat brain with electronics over time.
That's metal as fuck.
I think that would just kill you and replace you with a self-aware copy of yourself that thinks its you. Personally, I think modifying our body chemistry would be a better way of doing this.

massive amounts of energy and negative matter though to be required to create Alcubierre warp drives and wormholes.
It actually may be possible, Dyson Spheres can solve that energy problem. Additionally, we will probably have access to Fusion power. Imagine every car and vehicle running on a Fusion generator. That would be sick.
 
I like the Starlink concept. Obviously it Is going to be used by the military-industrial complex and the rural internet part is just a bonus for them farming folks.

really? to me, this is the only way to go digital and retain yourself. that's the entire point - it's a slow process that happens over time... years, possibly decades. meat brains are already incredibly adaptable to damage, but they can't regenerate at all.. so essentially the virus would intentionally damage and destroy your brain cells. but replace them with artificial versions. the meat should then utilize these pathways after the fact as it heals its functions. your contiguous experience of consciousness shouldn't be interrupted. my personal belief is that the experience of consciousness is "you". "you" are an ephemeral electrochemical reaction, informed by the arrangement of pathways in your brain. if that reaction stops... "you" die. a clone of you might arise from your embedded memories and experiences... but it won't be "you". if you get what i'm saying. scanning your brain and uploading it to a computer is just a clone. non-wormhole based teleporters would be ontological suicide... but to the outside world you would yet live. etc. i mean, we don't know, obviously. but it doesn't make sense to me that "I" would arise if my brain was simply scanned and copied. or, that "I" would be "me" if somehow my brain activity stopped and I was revived - say, with cryo preservation. it would be like hibernating your computer... you pick up where you left off.. but it's not the same session.

It actually may be possible, Dyson Spheres can solve that energy problem. Additionally, we will probably have access to Fusion power. Imagine every car and vehicle running on a Fusion generator. That would be sick.
the energy requirements are something we can theoretically achieve with technology that is probably possible, yes, but i've never seen them described as *only* requiring a lot of energy. they're supposed to also require negative matter, which is not something that has been proven to exist. i mean, sure, things can always change - but the various types of nuclear engines are the most-possible options achievable with current technology.
 
Apogee on YouTube has a few neat videos about current events in space exploration.

 


 
they can complain all they want, but if you want to do something more than take pictures and go home, it's REALLY hard to argue with 100 tons payload to lunar surface... hell, even more if you reduce the fuel tank size and just make a version of starship itself into a permanent base once it lands.
 
They are stacking SN20 on BN4 now.

Tis a beautiful sight to behold. I wonder how long until it launches. It looks like they haven't finished putting tiles on.
The booster doesn't need any heat tiles. Only the belly half of the ship needs tiles. It will be facing down during the belly flop maneuver. It looks like some of the tiles fell off but otherwise most of them are on.

Even if the FAA is not ready to let this launch, SpaceX can spend at least a couple of weeks on cryo tests and static fires. They also probably need more tanks than what you see on the left to supply the rocket with propellant. They were moving one around with that orange crane around the same time as the stacking.

Oh, I know that. I was talking about the ship. It looks like there are still tiles missing on the belly.

Regardless, it looks like it was just a fitting test, as ship 20 is back in the high bay.
