>>14996796
let me guess
It will be a little bit of moon footage with large chunks of someone talking in front of CGI slides

>>14996818
I could accept Gateway for political reasons if it was the only thing existing in Artemis for political reasons, but hell if we are going to be stuck with SLS can at least they invest right into a moon surface station?

>>14996809
I hope not, otherwise Artemis will fail as well. I'm optimistic, I would assume getting the upper stage to flip was pretty tough. The booster is big, but it just comes straight down like Falcon. The catching system still seems like bullshit though

>>14996824
I dunno I think a station in lunar orbit is cool
if they actually use it to stage manned landings I wouldn't complain but it'll probably be a once every few years deal

Janus is canceled.
You can say thanks to JPL.

>>14996824
Starship HLS makes surface moonbases cheap. Gateway is the correct place to spend money because there's no private sector demand for interplanetary manned solar-electric spacecraft yet.

>>14996818
>just announcing Japanese astronauts will be allowed to go to Gateway
And here I thought extension would mean an additional module

>>14996853
I guess Gateway is worth as an experiment for staying on deep space for extended periods of time, both for human health and technology matters.

>>14996855
It does.

What about DragonXL?

>>14996864
That's still going on (although will possibly be Starship).

Even though I know it means they're figuring out ways to cooperate without involving diplomats and their respective governments, the barter system used amongst international space agencies to avoid paying each other money will always look weird to me

>Earth! This is from Orion's Optical Navigation Camera on Flight Day (FD) 2! These cameras are being calibrated on this flight for future missions to be able to safely return the crew without any ground communication!
>Optical Navigation works by measuring the Earth or Moon diameter and limb (sunlight/darkness interface) to calculate how far and where Orion is relative to the body. Typical state (position) navigation is calculated by the radiometrics of the ground DSN signals.
>P.s. should also note this is one of those safety features/upgrades Artemis can have that Apollo did not thanks to advances in computing and optics in the last 50 years

>>14996929
you probably right, just a basic engineering pic

>>14996958
Cynder

>>14997000
Probably less, desu. The SLS is outrageously late and expensive because of the need to reengineer orangetankbad to take vertical loads. The center core for Jupiter III could have been made of aluminum.

Reminder that orange tank is made from thick curved plates of aluminum alloy that have 95% of the material milled out of them and are then friction stir welded to each other.

>Since 2010, Aerojet Rocketdyne has conducted over 520 tests of multiple configurations.
Over a decade without any meaningful achievements. Is there something wrong with RDE? The only relevant milestones I remember is the liftoff in Poland and the in-orbit test from Japan.

>>14997025
Could it have been possible to make it a balloon tank or would the SRBs break it?

>>14997024
Yes

Now that's an angle

>>14997000
You wouldn't need to completely redesign the shuttle hardware it's still side-loading. Don't forget that even with that, half the cost in SLS is Orion. Even assuming identical launch costs it's still a vehicle capable of sending several hundred tons to LEO.
>>14997003
Except for when there is. Like that.

>>14997036
>mun legacy hardware
it would have been an expensive piece of shit with a low launch cadence.

And?

>>14997050
Oh no, someone stole my white elephant, how terrible!

>>14997046
You were asking why people shit on it and that's the reason.
There's only so many engineers in the world and taking up a decade of their time on a rocket with arbitrary constraints where they could do so much better with them removed is an incredible waste.
We've done it twice now with the Shittle and SLS.

>>14997062
It looks like they're mounting grids to hang stuff off.

>>14997000
>>14997011
>>14997036

The Jupiter III stack doesn't require major redesigns of any major components. You just slap 2 shuttle external tanks and 4 shuttle solid boosters onto a stock Saturn V second stage. Individual launch costs may be slightly higher than the SLS, but far less money would need to be spent on engineering.

I can't seem to find any information on what engines they chose for the core stage if not RS-25's.

"EARTHERS could be here," IRyS thought, "I've never been in this orbital plane before. There could be EARTHERS anywhere." The solar wind felt good against her spacecraft's magnetic sails. "I HATE EARTHERS" she thought. HERE COMES HOPE reverberated through her entire crew module, making it pulsate even as the cost-plus Tang circulated through her powerful healthy veins and washed away her (merited) fear of anti-satellite missiles. "With a spaceship, you can go anywhere you want" she said to herself, out loud.

Booster static fires are increasing in engine count. Once all 33 fire at once it's time for a full WDR and then we're just waiting on the license.

>>14997230
Now that SLS has launched, the FAA has removed the indefinite hold on licensing the Starship demo

>so much for solar sails
Retard, Lightsail 2 wasn't intended to completely overcome atmospheric drag and LEO is so easy to access that most spacecraft there will have plenty of propellant for station keeping. Practically any non-demonstration solar sail mission will be launched into a much higher orbit.

>>14996932
Basically remember how in Apollo 13, they basically held the Earth within line of sight and then burned for 30 seconds despite the RCS system completely fucked so that their angle would have been sharp instead of shallow for reentry? That's basically what this is. Using the idea of that, but baked into the safety system so that in event of all loss of communication with Earth due to some catastrophic hardware failure, the onboard computer can keep track of the Earth and return home.

Pretty cool.

Inverse square law. They make the most sense in the inner system, which has been mission starved for decades. Japan did use one for a Venus mission (IKAROS), and NEA Scout is staying inside Mars orbit. For the outer system they make the most sense as hybrid "power sails" to carry thousands of square meters of photovoltaics at low mass, but that tech isn't ready yet. NEA Scout is a precursor for that per NASA, and that new 30% efficient helicon thruster design would work well for that.

The problem with Starlink is that the antennas are pointed in exactly the wrong direction to talk to something headed out into deep space. We're probably going to end up ditching a big radio dish based network for lasers anyway.

Some preliminary work, sure, but I don't know how far they might have gone beyond "here's what we're learned from LS on Dragon and here's how we think we can expand on those capabilities." The only real way to check would be to see if there's a public notice about NASA paying out for a life support related HLS milestone.

I do RDE research. There's a shit ton of experimental work being done on them in propulsion labs, but no one's anywhere close to delivering one as an operational propulsion system. I haven't read the paper from the Japanese flight test yet, but I think it was around a 6 second burn, which is fairly long in this field. I think the record burn time for any RDE is around 2 minutes or something like that. I don't think we'll see any serious implementation of RDEs until the late 2020s at the absolute earliest.

As far as I'm aware, AR has probably done more RDE research than any other corporate entity (at least publicly). Their lack of progress is more due to the immaturity of the technology than anything else. A few startups have latched onto RDEs recently as well, but I'm fairly skeptical that they'll get anywhere at this stage. AFRL and other government entities are doing a ton of work on them too.

I just noticed how NASA talks A LOT about ancient life on Mars. Seems they believe it likely existed.

>>14997695

>>14997697
to distract from the fact they absolutely refuse to search for present life

>>14997697
more like they know it’s a popsci selling point for public interest, and by extension congressional interest
also the fact that it was a water world with sedimentary rock deposits that is somewhat easy to get to (at least america has gotten really good at getting there) makes it worth studying as an analog to earth
I don’t think it’s so much about “there are ayyys there!” as it is “these are really interesting conditions”

>>14997699

>>14997697
They believe it's a possibility. I've asked about where to find fossils on Mars here for this reason. But it might be just a meme like the martian canals used to be in the end.

>>14997697
The case is fairly strong. Current belief is that there was liquid water at one point, which is the gold standard for habitability. Life developed on Earth pretty soon after it was first habitable, and it's likely that even a relatively short window on Mars could lead to the same.

>fairly strong
fairly strong relative to almost every other place in the solar system, just to clarify

>>14997716
Not really. The case is much stronger for the various icy moons in the outer solar system, but those are much harder to investigate because of:
>Distance makes communication very slow
>It takes forever to reach there with the gravity assists
>The probe would need to dig very deep into the ice to reach the underground seas, the only exception is Titan's hydrocarbon lakes.

Who DeSantis would pick to run NASA in a possible term with him?

>>14997731

>>14997722
I think Titan and Europa are more likely to contain life right now, but Mars is equally, or more, likely to have contained life at some point in the past. If life somehow exists anywhere else in the solar system then it almost certainly exists on all 3 of them.

>>14997695
>>14997709
>>14997713
where are the radiators?

>>14997737
But as I said, they're harder to explore. Compare the time Dragonfly will take to reach Titan vs the time a Mars probes takes to arrive.
In another point, I think there is still a case to be made for Venus. The chances of life there are much harder, but if there is It's easier to find. There is no need for tunneling through kilometers of ice and if you find something it won't be dead like Mars, and life in a planet without water would be much more groundbreaking.

>>14997731
DeSantis would dump contracts with SpaceX and put ULA back at the front. Manned space travel would end.
DeSantis is just a talking head for globohomo.

>>14997752
Venus is a bitch to explore too, even though it's closer. The surface conditions are absolutely nightmarish and the atmosphere isn't much better, especially since its weather patterns are absolutely insane. I have a hard time thinking life could survive there (even if it's wildly different than Earthers), and if it is there then it would be nigh impossible to find with present technology. Honestly Titan is probably the best choice since it has a shitload of organic compounds, and any life forms would be really interesting since they'd have to be very different from anything on Earth. Europa is cool and all but there's no clear evidence that it has the same access to carbon and nitrogen that Titan (and Earth) have, even if subsurface conditions are absolutely perfect to sustain early Earth organisms.

As an aside, I think Titan is the most interesting celestial body and hope that they send more probes there. The thick atmosphere and oceans also mean there's much more possible variance to mission, compared to Mars which basically just needs rovers, and that makes them way more interesting.

>>14997731
DeSantis is do fucking based. Any chance he gets he gives Elon mad props

>>14997781
Titan is severely underrated in the common mind. It angers me that solar system charts never try to include the major moons of the solar system, and people rarely talk about them. Titan is the only place other than Earth that we know there is liquid on the surface and barely anybody outside of enthusiasts and scientists know that.

>>14997772

>>14997599
Why don't they just download the video files the same way they do with the Mars orbiters and landers? It takes longer but then you don't have to wait for the Orion to return to Earth.

>>14997752
Venus is literally Hell with 800 degree surface temperatures, crushing atmospheric pressure and acid raining down everywhere. The only life that could possibly exist there is something like the xenomorph from the Alien movies.

>>14997808
upper atmosphere

>>14997790
Yeah. There's a lot of interesting places which get ignored because no one cares enough and it's a hard sell for the few people who do when they're fighting with a dozen other missions. Private funding isn't particularly promising either since there's little profit and launch costs are only like 10% of the overall mission price.

I just hope that *someone* books a Sedna mission, since we're close to a launch window that occurs every 12,000 years and it would give data about the solar system that can't really be obtained elsewhere.

>>14997814

Now that you mention it, I hope too, and I have been so disappointed with space exploration that I won't be surprised if they waste this opportunity.

>I won't be surprised if they waste this opportunity

In the late seventies and early eighties every space agency put together proposals for missions to Halley's Comet for when it swung back through the neighborhood in 1986. NASA had several ideas in the vein of the Mariner Mark II series, but a rendezvous would require a rocket in the same weight class as the Saturn V and the various flyby proposals weren’t seen as able to produce enough good data. There were some vague plans to have Galileo launch earlier so it could perform a flyby while on route to Jupiter but this was also rejected due to the need to add additional debris shielding to the probe.

Meanwhile, ESA launched Giotto, Japan launched Suisei and Sakigake, and The USSR redirected Vega 1 and 2 after their flybys of Venus, forming what would be called the “Halley Armada.” Giotto and the Vegas were fairly large multi-instrument probes, but Japan’s entrants were 140 kg dinksters launched on the equivalent of a multi-stage bottle rocket and they still managed to do useful UV spectroscopy during their flybys.

Never discount NASA’s ability to pass on opportunities for the dumbest of possible reasons.

>>14997842
/sfg/ was literally the first place on the Internet to notice NEA Scout talking to the DSN. NASA hasn't acknowledged it yet.

The more I learn about NASA, the more I hate them.
They can put amazing effort but only if it is for a grand, "first", flashy project, but they are retarded about everything else.
Imagine how much they could do If they dedicated a Saturn V class rocket to send probes all round instead of just sending an astronaut to put a flag on the moon.
I'm honestly sad Europa Clipper won't go on the SLS, the trip would be so much quicker than the Falcon Heavy option.

>>14997873
>shitting on Apollo
this must be bait

>>14997873
Thats not because of their choices, most of NASA'a blunders are because the government refuses to fund them more.
The Space Shuttle being a big, potential ticking bomb was entirely on the government demanding NASA for the Shuttle to be capable of doing way too much shit like deploying satellites, when originally they just wanted a small ship to ferry astronauts and some cargo to LOE, something like the Dream Chaser, and not the gigantic, sluggish fridge it ended up being.

>>14997880
Don't get me wrong, I love Apollo and it was fair for the time, but I hate the prospect that Artemis is just going to be a repeat.
Waste a bunch of money with SLS. Fuck around the moon for a bit. Get cancelled when the US inevitably gets into another war and needs to pump money into it. Another 50 years stuck in LEO.

spacex cant just build rockets out in a field

>>14997867
Wondering if these missing cubesats are still stuck inside the upper stage

>>14997888
We now have a relatively thriving private space industry to pick up the slack when Artemis starts to decline

>>14997884
I don't hate their scientists, but the NASA administration is part of the problem since they work for government interests with the contractors.

>>14997855
Watching it now. I like it so far. He’s talking about methane recondwnsers

>>14997893
That's why I'm hoping on the success of Starship, and I'm optimistic about it, but there is still a fear that it could fail despite everything, and the only ones "trying" to make something like it are fucking Blue Origin.

>>14997888
Thats why NASA is giving billions for Starship's development, they know its just a matter of time before the government snaps and slashes SLS production like they did with the Saturn V.

>>14997873
>just sending an astronaut to put a flag on the moon
yeah…
Also, Apollo/Saturn V only was viable because it was flashy and grand. They never could have justified spending an equivalent sum on probes, even if it would have arguably led to more scientific knowledge. What makes me optimistic is that manned spaceflight has potential for a strong commercial market which can provide manned missions to the Moon and even Mars, leaving NASA to focus on the stuff which will never be commercially viable while purchasing rides/launches as needed.

>>14997903
This is pretty much my most optimistic scenario for space exploration.
The private sector focuses on direct commercial applications and the dirty works like rockets, while state agencies like NASA focus on missions that are not profitable like rovers and telescopes.
I'd like a scenario were there are more than a single flagship at once.

it's pretty good. spin primes are even more batshit than he mentions though.
they pump a whole lot of oxygen through the injectors as well as methane.
they must be running it at a mixture ratio they deem safe enough.
thus any oxygen vapours already existing from the pre-chill process take it over the edge to an explosive mixture.
