First for Richard Branson

First for dyke on the moon

nth for propane fuelled engines.

Would tracked vehicles like halftracks or tanks make sense on Mars?

>>12766920
they're an utter bitch to work on and need quite a bit of maintenance so outside of heavy equipment i'd say no.

deldaiih

Most likely, but they haven't been done due to weight limitations

>>12766923
what a lot of boosters

>>12766920
No. We will use spider tanks on Mars.

>>12766927
wew ere looking into gatting moar of them
but we were banned

>>12766942
'elf and safety gone mad. it should be every mans right to own as many boosters as he wants, and fire them as he pleases.

So... What's /sfg/ toiling with in KSP?

FTS is installed for tomorrow's attempt.

>>12766994
Those are the explosive charges right?
>>12766970
Last thing I made was a KSP ripoff of a JPL lander. I had a manned rover/skycrane combo, packed inside of a head shield with parachutes. I turned on realism overhaul and tried to see how fast I could reenter from orbit while trying to nail a landing back at the spaceport

>>12767008
did you buy or pirate ksp

>>12766922
+ work exactly as well across all pressure environments
+ all terrain, won't be bashed apart going over rogs
+ no exotic components
- heavy
- occasional maintenance or replacement (no different from meme-alloy wells)
Treads are the best if you don't have autistic weight requirements, prove me wrong

>>12767015
wheels* not wells

>>12766913
I hope we get some inevitable new glenn crash pictures

>>12767014
Bought it. It’s not that expensive but it should be free. Fucking thing runs on the clunkiest coding ever

>>12766917
Dream Chaser may be using propane. Also there's a smallsat launcher using it, but I forget which one.

>>12767019
They will be on that shit like Roswell

>>12767015
you've never thrown a track in the middle of nowhere and had to get it back on. doing that in an eva suit would be hell.

>fucked up the current active thread
I'm sorry, I'm just going to repost.

>>12766471
Honestly, I was seriously considering how easy it should be to make something like this nowadays. There's a bunch of shitty university cubesats being launched nowadays, all that it takes it for one to have an actual computer and not just a shitty microcontroller for you to be able to take it over. I know some missions that have this, however their security is usually high for communication requirements. I want to write up a report on how much it would cost to launch your own private tracker/p2p file sharing server that you could talk to with UHF or something. Just the bare minimum to make it off-world and untouchable by some government agencies. I think that it is still much too expensive for pirates, but it should definitely be possible in a few years.

>>12767020
its 40$

>>12767029
Theres been this thing where Pirate bay tried to launch their satellite to circumvent some regulations but it didnt work

Do you think you can fuel a rocket with pure seethe?

explain this shit

>>12767025
I know it's a bitch, but I don't see how the alternative is better. It's not treads vs. traditional wheels where the debate has a lot of nuance. The best we have is basically unshod wagon wheels made out of meme materials.

>>12767037
I fucking wish, I'd be on Titan by now.

>>12767030
I think when I got it, it was cheaper? It was 2012 and I was in 8th grade so my parents bought it for me. For reference I am now graduated from college (and I still suck at ksp)

>>12767041
skycrane attachment?

>>12767041
They were broken with explosive charges unironically

>>12767041
That's the root of the electrical umbilical. When you see the skycrane lowering the rover, there's one cord of the 4 that looks curly, that one connects the rover and skycrane and gets mechanically cut at when the skycrane flies away.

>>12767037
Ask the EM drive guys

>>12767050
more info on cutting mechanism?

>>12767044
if you've got the ability to put heavy tracked machinery on mars surely you can use vehicles with non-meme wheels like on any standard 4x4.

>>12767056
If Mike McColluch can actually get a QI drive to work, it might as well be powered by copium and seethium. The academic side of physics will be so pissed off

>>12767060
explosive shaped charge.

>>12767063
Rubber doesn't work so well in near-vacuum or extreme temperatures, let alone both.

>>12767035
Care to elaborate, or link to story? This should be perfectly possible nowadays, however the state that is responsible for the launch is still legally responsible for whatever hardware they put out there, so I can imagine that they would never get this approved this easily.

>>12767072
eh i'm out if ideas then. tracks it is. if in 30 years time i see you trying to fix one on the edge of some crater i'm walking right on by though.

>>12767060
https://psemc.com/high-speed-pyro-cutters/

It’s essentially just a tiny shaped charge. Similar devices are used to separate Rocket stages

Finally new rogg images yes

>>12767047
>Sharing a thread with the zoomest of zoomers
Honestly keep at it anon, good to see you here. This only makes me feel old...

>>12767079
WOW this is cool

>>12767079
I never thought that I'd get excited by seeing a bunch of roggs, but the fact that we can even get these images brings tears to my eyes...

>>12766970
I have been playing plenty of RP-1 lately, trying to find a solid start stratergy to get orbit by 1953 but research times or construction times keep fucking me.

>>12767079

>>12767079
these rogs are making me salivate what the fuck is wrong with me

here we can see a bunch of rog specimen bathing in the sun, and looking behind them we can see a cliff which is a common rogg formation

>>12767099
you thought they were going to have their bomb designs sat out there on the internet for any tom, muhammed and chang to look at?

The 4ASS thing is real, or is it the product of the farmer anon?

>>12767107
they seem very excited about that rog formation. they keep going back to it.

>>12767108
>bomb
It's an M-80 in a tube, I don't think it's exactly a state secret. What are they afraid of, rogue wire-cutting terrorists? Scissors exist.

This may be for /sqt/, but does Mars have winds? I suppose that it could have them, but I am not sure

>>12767120
Rails lines are iron, at least where I live. Besides, aren't abandoned houses a far easier source of copper for methheads and the like to strip from? Even then I don't think some crackhead is going to use a loud explosive-cutter charge to cleanly separate chunks of pipe while stripping a house in the middle of the night.

My fault in expressing. The railways have some cables nearby, which are made of cooper. So it would be possible to strip kilometers of cooper wires with a little bit of preparation

How did the farmer anon originally share his writeup? I'm a geologyfag and I could give a writeup on the geology summary of Mars, the geology of different areas and what to expect depending on where you land, and the geology of all these Perseverance photos. It would take me a while but I could share my results

>>12767138
>notable contributions to the space industry include engines that look like pipe bombs whos inventors suddenly stop posting,
I laughed at this

>>12767117

>Biological treatment of perchlorate is very similar to denitrification, and denitrifying bacteria have been found to be capable of degrading perchlorate.

>>12767184
So why don't we just shower Mars in thousands of tons of bacteria?

>>12767190
Hey we might have a use for that perchlorate
>The dominant use of perchlorates is as oxidizers in propellants for rockets, fireworks and highway flares. Of particular value is ammonium perchlorate composite propellant as a component of solid rocket fuel. In a related but smaller application, perchlorates are used extensively within the pyrotechnics industry and in certain munitions and for the manufacture of matches.[4]

This is going to take for fucking ever. But share what you would like in the report. As of right now I'm going to base it off of the Roadside Geology book series (if you are familiar):
• Introduction
• Crash course of geological history of Mars
• Modern surface comparison of Mars with Earth
• Likely spots for colony and the local geology of said areas

>>12767369
Why does it take them two weeks to start driving?

>>12767380
Mars weather basically covers the entire planet surface in a fine oxidized dust. As soon as rovers like Curiosity drilled or brushed rocks it revealed rocks of different colors.

>>12767382
Turn on the rover, take pictures, figure out exactly where you are and where you want to go, take more pictures, construct VR environment to walk around in, take more pictures, have several staff meetings, take more pictures.
There's lots to do first anon!

>>12767382
First week is to gradually upgrade both rover computers from flight software to surface ops software and then the rest of the time is to commission all the systems to verify everything is functional and working safely.

Does anyone else unironically like watching the Everyday Astronaut? I enjoy his videos on specific topics because they’re fun and are 20-30 minutes long. I also like his livestreams because he’s very informative. I know he’s a bit uh “DUDE SCIENCE” but I still like Tim’s stuff.

>>12767383
>the whole planet rusted
Why was water being there ever even a question?

>>12767387
His videos where he delves deep into the engineering numbers to compare various systems are nice. He just goes a little too far on politics on his livestreams.

>>12767388
Ever released chlorine gas into a lab with metal impliments around? Shit rusts instantly

Hellas Planitia in the southern emisphere would be a good place for a colony. Highest atmospheric pressure on Mars and confirmed water. During the summer there could liquid water with the combination of temperature and pressure. I'm going to pop a dome there and start experiments in growing Antarctica flora there.

>>12767403

>>12767434
I think the complexity of Raptor is overstated, the workings are pretty simple and just metallurgically intense

>>12767431
>krystalposter sneaks into boca chica and slaps a krystal nude on a raptor

>>12767440
true. it's no more mechanically complex than a modern 4stroke. just has to deal with a lot more and doesn't (yet) benefit from mass production in the millions.

Who knows but if it was OldSpace they would’ve shut down engine production until it was fixed

>>12767493
rocket engines by definition operate on the edge of failure. The margin between being useful and failing is quite thin. This is also where the difficulty comes into play: faults in the system are magnified by the intense conditions, meaning that compared to other engines a rocket engine has to go further in the approach towards perfection.

>>12767505
They looked stenciled on, nothing that could break probably. My guess is that they want to move away from numbers on the Raptor bells, but after the last one went unnumbered and everyone noticed, they made it as big as possible for shits and giggles.

>>12767594
The Apollo 14 episode from "From the Earth to the Moon" is pretty kino

>>12767583
Look at all those dead pixels from radiation

>>12767602
Curiosity landed at the bottom of an ancient lake bed where things slowly layered in. Perseverance landed at a previously more active river delta location. More rapid erosion and geological events.

>>12767612
Just imagine how many more interesting roggs we've been missing out on.

>>12767602
Well Gale Crater is pretty interesting too, but they chose it for it's high volume of sedimentary rocks that outcrop (because it is believed to be a dry evaporite lake). Jezero Crater is a bit different. It is floored by basalt, like the rest of the surface, but the difference is that it had a huge inlet of water which lead to a delta. Instead of evaporite sed rox everywhere like we see with curiosity, Perseverance sees tons of basalt that has been weathered by water, along with active sed rox deposited as part of the delta system

>>12767567
I'm always preoccupied by massive cringe when people pronounce it "Jizz-erow" to think about anything else
It's from Proto-Slavic and you should read it "Ye(h)-zeh-ro"

>>12767523
I hope not

>>12767621
Out of all of the possible landing sites across Mars, Jezero is definitely in the top 10. The only other places I think need to be explored (hopefully by humans) would be the general layout of Valles Marineris, all those mysterious holes and lava tubes, sites with known avalanches, and places with active chemical serpentine cycles (likely from ancient hydrothermal vents). I would also add carbonates to this list but I'm pretty sure Jezero has a ton of them and it's one of the main goals of Perseverance

>>12767610
no silly those are just the ground stars

>>12767637
Now that JPL has confirmed the terrain detection/navigation landing system works, they will be more confident about selecting even harder to reach interesting landing spots

>>12767629
Im slavic and I say jizzero would be weird otherwise

>>12767647
Yeah I don't disagree but also we are about to send humans to Mars. A human can do in 2 days what a rover can do in 2 years. Although we should be wary that the initial colony will be at one spot and the rest of Mars could still use rovers for a while. I think the (new) way of doing it should be JPL just sending a rover/skycrane along as part of cargo starships. Rovers could be landed across the entire surface and then the JPL landing coding could help them get to places

>>12767637
Great thats just 3 more Mars missions before we can think of Titan or Europa
>>12767647

Oh well Titan is vastly more based than Mars in every way. I was just throwing out food for thought

>A human can do in 2 days what a rover can do in 2 years
disagree at this point it doesnt make much sense to send Humans if your goal is science. A rover does more science than a human it just takes longer for a rover and rover missions are much cheaper

>>12767664
My point was that we will (soon) have the ability to get geologists on the surface. They can hammer out rocks and soil samples and bring them back to a lab where they can use all the tools a rover has, but better. Rovers are built with mass in mind and thus have bare-bone science equipment. For example perseverance has a raman spectrometer, mass spectrometer, etc. but they are very very fundamental. SpaceX would be able to land WAY better equipment for labs that could do so much more

>>12767664
A dude with a shovel can do more in an hour than any lander or rover has done. No spacecraft has ever done a true deep core sample of Mars ever

>>12767636
yeah, pretty clear that that was pushing things too far.

Speaking of the Starlink 19 entry burn failure, I was trying to make sense of the anomalous plume seen before telemetry loss. It's shooting out towards the side. If the booster was still approaching sea level in a nominal, upright, orientation, wouldn't this plume be instead facing towards the camera? Does this imply that the booster was falling sideways at this point? What do you guys think?

Where is the geology guy? I hope he is doing well

>>12767664
“Science” is a fucking retarded goal. Colonize or prepare to colonize, or it’s a retarded waste of time and the people who say space exploration is a waste of money are objectively right.

Elon is an idiot, a true moron in ever sense of the word. The reusable rocket technology SpaceX spent years developing is self defeating because its more efficent to use a expandable rather than a reusable Falcon 9 on a pro-rated basis. $62 Million for 22,800kg into LEO with an expendable F9 means a price of $2720/kg. $50 Million for 15,600kg into LEO with a reusable F9 means a price of $2720/kg. You are literally spending almost $500 MORE per kilogram going reusable, it would be cheaper for SpaceX to fly the F9 expendable from now on and it would have been better if they never fell for the re-usability meme at all.

>"B-B-B-B-BUT RESUABILITY MEANS SAVING MONEY"
Not if the ammount per launch saved it offset by a reduction in payload capacity, sure a reusable F9 costs 20% less than expendable, but also has 32% reduction payload capacity. It gets even worse with the Falcon Heavy. Which can put 63,400 kg into LEO when Expandable for 150 million, as opposed 28,400 when reused for 90 Million, $2350/kg vs $3630/kg respectively a difference of over $1000/kg.
Why is musk considered a genius again? Is paying more per Kilogram to LEO, using rockets in thier inferior configuration, some big brained idea that only SpaceX could have pulled off?
Let's face it, re-usability is a meme. You all fell for it because the heckin' Muskerino convinced you it was smart and that you were smart for believing him, using his only real talent marketing.

>inb4 "Shill"
>inb4 "Thunderfag pls go"
>inb4 "So how much is ULA/Blue Origin/Roscosmos/ect paying you?"
>inb4 "Who at SpaceX hurt you?"
>inb4 some other irrelevant lockument
Don't even bother to copepost, there's no getting around the fact that SpaceX is welfare leech no different than a sheboon and her 5 nigglets fathered by 4 different men. SpaceX making up their losses on commercial flights with largess from the government isn't innovative. Its just Musk stealing another idea from many who proceeded him, and pretending that its his own.

If reusability was more expensive, then SpaceX simply wouldn't offer it as an option.

No one knows. I’ve seen speculation that it’s because the booster lost control and started to turn and ended up breaking apart because of the forces. It’s also been noted that there’s a possibility of an engine eating itself on shutdown and spewing bits of debris out. One thing is certain though, and it’s that if SpaceX wants to keep testing reusability, they’ll have to take it easier on the cores. At least Superheavy does RTLS-only

So fucking kino wow. Also they almost fucked up the entire mission. The Euros had shitty programming that almost made the entire mission unable to communicate with Cassini. IIRC they barely got away with it by using some quick hack they had to send to the lander, but they still ended up only getting half the data they were supposed to.

>>12767411
I can tell you've worked with a lot of plumbing. It's "load bearing" until they actually connect the plumbing. If it was an oldspace engine, they probably would have spent 5 years developing a custom piece of resting equipment for it.

The good thing about SN9 is that everything up until relight worked the same as SN8, so I feel more comfortable about that phase of the flight now. I'm a bit worried about an engine failure on ascent though, since it's weird that they've had so many problems otherwise but have performed so reliably with that. Also, there are still ways that it could land hard or tip over even if the engines work on landing.

>>12767981
Keep telling yourself what you want to believe, it might even help you pretend that you're a really woman as well.

>>12767991
An engine failure on ascent scares me too seeing as Raptors have a shitty record with static fires. That would be embarrassing to because it would legitimately be backwards progress. I’ve been worried about the ascent since SN8

That WISPR can do this comes as a complete surprise to the Parker team, according to Angelos Vourlidas, the WISPR project scientist from the Johns Hopkins Applied Physics Laboratory (APL). This device is “tailored and tested for visible light observations,” said Vourlidas in the NASA statement, saying they “expected to see clouds, but the camera peered right through to the surface.”

“WISPR effectively captured the thermal emission of the Venusian surface,” added Brian Wood, an astrophysicist and WISPR team member from the U.S. Naval Research Laboratory, in the NASA release.

WISPR, it would seem, has an unexpected capacity, namely the ability to detect near-infrared wavelengths of light. If confirmed, NASA says this could alter the scope of the missions to include investigations of dust around the Sun and also within the inner solar system.

>>12768113
https://www.nasa.gov/feature/goddard/2021/parker-solar-probe-offers-a-stunning-view-of-venus

That aspect of the image took the team by surprise, said Angelos Vourlidas, the WISPR project scientist from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, who coordinated a WISPR imaging campaign with Japan’s Venus-orbiting Akatsuki mission. “WISPR is tailored and tested for visible light observations. We expected to see clouds, but the camera peered right through to the surface.”

>>12768105
The Apollo lunar module costs $380 milllion in today’s dollars. It could put 5 tons into the surface of the moon when deployed from low lunar orbit. The descent stage masses 10 tons so the whole thing was about 15 tons.

If you use Methalox or Hydrolox on the descent stage instead you get about 1 km/s extra delta v, which would allow you to land on the moon from a trans lunar injection.

The vehicle has a mass of 15 tons so it can be launched straight to the moon using an expendable Falcon heavy. FH expendable costs $150 Million plus $400 Million for our upgraded lander and that means you can put 5 tons into the lunar surface for $550 million. For reference, a Delta IV Heavy costs $350 million per launch

>>12768099
He's been quoted as saying that a reusable Falcon 9 FT launch goes for about $50 million, the rocket when expendable is $62 Million. 50/62 is .8, so a reduction of 20%.

>>12768112
Launching 45 tons of cargo on two expendable F9s ($124 million) in 2, 22.5 ton payloads is more economical than launching on three reusable F9s ($150 million) in 3, 15 ton payloads.

TOP PRIORITY MISSIONS:
• Venus lander
• Venus sample return mission (not impossible but it would be a logistical nightmare)
• Titan mission ASAP, Dragonfly is based but it's going to take forever to launch
• Europa-clipper style mission WITH LANDER so we don't have to wait 20 years
• Cassini-style mission to visit Uranus or Neptune. Needs to be launched ASAP because it will take a LONG time to get there if we want it to go slow enough to actually be able to enter orbit
• No more fucking Mars missions, no more asteroid missions, no more climate satellites

>>12768123

I disagree on the Mars mission part. We need an ISRU lander that can mine ice to see if it’s possible.

>>12768126
If the cost of a launch really was going down as much as its said, that should be reflected in the prices if its not being kept artificially high past what's marginally profitable. I thought Musk wanted to reduce launch prices?

>>12768135
>that should be reflected in the prices if its not being kept artificially high past what's marginally profitable.

The launch market is not particularly elastic, and he's still the cheapest option while increasing his margin. Why wouldn't he charge as much as he could get away with when he's paying for two Manhattan Project scale technology R&D efforts that could make or break the company at the same time?

Oh also of note is the fact that Sedna is about to approach Perihelion. It will still be far as fuck at its closest approach, but theoretically [theoretically] we could launch something that could land there and then just sit and transmit. 10,000 years from now it will be at aphelion and rival that of the voyager probes lmao

Venus is objectively useless in it's current state, but was potentially habitable in the distance past. It's an interesting candidate for terraforming, and learning how Venus went from a garden planet to literally hell is probably important to make sure it doesn't happen elsewhere.

Just because you can't colonize the surface doesn't make it useless. There is a lot to be learned from a geology standpoint by sending a rover sturdy enough to waddle around down there and collect data. It could be done pretty cheaply as well
