Stellarium is universally considered to be the best. There's a phone app that's very useful when you're outside, but there's also a desktop version. For greater autism, there's Heaven's Above, which gives more information (pic related). I also like to use https://james.darpinian.com/satellites/ because it tells you any passes ahead of time. The information from all 3 is very accurate for ISS passes (I've used it before), but I haven't used it for anything else.

OFT in August 2021

>>14756872
Would've happened if they got the greenlight.

>>14756883
Would have flown, possibly worked or failed the first time. Few months later, another batch of OFT, then another, then another, every 2-3 months.

>>14756822
I used a couple of those a year or so ago to see when the most recent Starlink train was passing overhead and got to see them because of it, very cool.

Reminder to /sfg/ that typical radiation dose rates in deep space are not a big deal, all of that radiation apart from cosmic rays are easy to fully block, and cosmic rays are only difficult to block on vehicles which must move from A to B, as big stations and ground habitats can trivially afford to use enough shielding material to block everything.
Reminder to /sfg/ that low gravity conditions aren't the same as freefall conditions, and the relationship between human health and reduced gravity is likely to follow either a sigmoid curve or a square root curve, not a linear or exponential curve. Also, with spin gravity, surface gravity becomes irrelevant to health, and in fact a lower surface gravity makes building an orbiting spin habitat much easier (with low enough surface gravity it's easy to do upright spinning cylinders directly on the surface, too).
So uh basically there's no practical barrier to colonizing the entire universe except for getting off of this high gravity rock in the first place.

https://files.catbox.moe/3s210i.mp4

>>14756895
Humans can survive in low gravity perfectly fine. The only reason you'd need spingrav is if you want your children to be able to travel to other higher gravity planets and places, like a Martian traveling to Earth. Pretty fucking important, but technically not a necessity.

>>14756883
They still haven't handed in their 5000 word essay on Texan history. Until then they are simply unable to launch.

theoretically you could most likely do this with the jovian radiation belts as well, even if just in localized areas around the moons, as its still the same type of particles.

>>14757296
how am i the retard? you're the one who didn't know about something thats been discussed on sfg hundreds of times before

>>14757284
It's charged particles, you can in principal use a long tether with an electromagnetic field to deflect those charged particles and neutralize them (which lets the high velocity particles simply leave the Earth's magnetic field). Tricky but not impossible with modern materials and shit.

Earth's radiation belts are kind of not a big deal at all, but this concept becomes much more interesting if you look at discharging Jupiter's very powerful radiation belts. A significant reduction in belt intensity would mean a simultaneous decrease in the challenge of exploring everything in the Jovian system within Callisto's orbit.

>>14757276
>Freefall is identical to zero G

>>14757052
It's like being in the interplanetary space between the two planets but since the Sun is blocked half the time, the dose is halved. Shielding is really just a mass problem, easily solved on Mars through covering the habitation with regolith but for the transit future astronauts will likely just have to accept the non-life-threatening dose or perhaps pay a premium to stay on a large Aldrin cycler spacecraft that would transit Earth to Mars in 146 days. It would have far fewer mass limitations, so very protective shielding is easily achievable and it would serve as a destination for multiple outgoing ships. The alternative is a faster transit but near-term propulsion will likely be limited to 3+ months.

>>14757302
>>14757311
What about inducing some kind of planetary lightning bolt that shoots the radiation into the poles?

Puny humans will never become interplanetary lel

>>14757334
Transfer to Mars, Venus, and many asteroids is short enough to just eat the dose, but transfer to anything farther will require better shielding solutions/propulsion options. ~4.5 months to Mars is fast enough to avoid a big dose. Jupiter in 12 months for example is too long, would result in significant dose. However, by the time we are even considering real human missions to Jupiter, we will likely have the orbital construction technology to simply build gigantic spacecraft with negligible shielding mass fractions that still provide an Earthlike radiation environment (a 2m thick blanket of HDPE plastic shielding masses far too much for a Starship sized vehicle, but for a Hindenburg sized vehicle it's feasible, and for a vehicle the size of several ocean freighters stacked together, it's minimal).

Half-true. Earthers will never become interplanetary due to flaws inherent to Earther culture, but Spacers will due to their superior cultural identity.

>>14757352
Are you really that stupid, or only trolling? It's a mere carnival ride with no chance of reaching an orbit. New Shepard is like driving up the Matterhorn in a bus instead of climbing Everest.

>>14757526
Yeah cyclers only make sense if they are actually very large and offer things that a departing spacecraft cannot. Since we're gonna have Starship, a cycler necessarily needs to be much larger than Starship to make sense.

>>14757355
If you are freefalling to earth, you are doing so because G.

0 G would be no free falling, because theres no up or down to fall too, there's no falling.

Feeling free falling is feeling gravity push and or pull you down

>>14757572
you're retarded if you can't reason they feel the same.

>>14757403
Could external and internal ship chamber shielding help? Like safety deposit box inside safes inside a safe inside a bank vault in a bank vault in an armoured room in a bank?

Any possibility of a moving tread like outer shell as a possible active deflector to richochet particles away? Or do these particles pierce everything, and if the outer shell is spinning the radiation would pierce it and possibly even be accelerated by it?

>>14757582
Well sky diving you would feel the air.

There is no reference point so falling towards a massive mass at a steady rate feels like not moving at allz if there is no wind resistance, there is nothing to feel.

So it's kinda like you are trapped in a large feathery cushion and gently walked with it some distance

>>14757563
UHMWPE + nano epoxy made of reactive graphite to create a more bonding is good light radiation shielding material.

In general polyethylene material works well as anti-radiation, but with UHMWPE + nano epoxy, it works quite a bit better too. We can make anti-radiation clothes/suits out of it , or just put a cover around the ship/crew quarters with it and it would provide a decent protection. And the material is already widely used so its cheap too.

Snate part 2. Mostly good but ends in catastrophic failure

>>14757704
Yeah so the answer is, the human mind/brain/body is designed to detect a change in state, and if it is experiencing a constant, a constant motion, it experiences an equilbrium of that moment, and that equilbrium expresses itself to the human, as stillness

>>14757572
doesn't matter to the biological systems we're talking about so basically fuck you.

>>14757704
Consider picking up a log in the woods, with an amoeba on it, and walking 100 yards, does that amoeba sense any changes, and is it only because a lack of detector ability, or as long as the log is picked up and carried smoothly, the amoebas immediate environment will not vibrate and shake.
Though if you are carrying the log and it bounces every step you take, wouldn't this vibration get to the amoeba?

>>14757572
>Feeling free falling is feeling gravity
There is no "eyes closed" experiment you can do to detect the difference between falling in a 100 G gravitational field and falling in a 0.00001 G gravitational field. They feel identical because they both feel like no acceleration at all. This is because gravity isn't actually accelerating you, it's accelerating the region of space you occupy, and you just come along for the ride. When you stand on Earth or Mars, the force you feel is actually repulsion due to the Pauli exclusion principal acting between the electrons of the ground and your body, as the space you're in continues flowing down towards the center of mass of the planet, but you are prevented from following it. While standing on Earth, you need to accelerate 9.8m/s per second just to stay in place, and this is accomplished through quantum mechanical effects as I mentioned.

>>14757590
One concept is to have the main vehicle be very lightly shielded, basically only good for typical solar wind, and to have a much thicker but smaller internal shield surrounding a small volume of space which people can shelter inside if there's a major solar flare. These flares result in perhaps 10,000x as much radiation flux for a few hours, then abate. This tiny shield still weighs several tons but it's far lighter than shielding the entire vehicle to that degree. Also, astronauts can use it as their sleeping cabin during normal operations to help reduce some cosmic ray dose during a long transfer.
Radiation particles move at a significant fraction of the speed of light, so the movement speed of any object is irrelevant.
Also, stop being a fucking retard and go google these basic questions.

>>14757635
Fundamentally blocking radiation requires mass in the path of the radiation, so while some materials are slightly better or worse than others, even the best possible material is still going to require several thousand kilograms per square meter of habitat wall area to produce an Earthlike radiation environment on the other side.

>>14757806
I predict disintegration on reentry, booster simulates its "landing" in the gulf fine though

>>14757965
If you could ask the smartest humans on earth a question or a few in these space relates fields, what would they be, provide me with example of what non retarded non basic questions look like.

If I had that opportunity I would have made sure to do my homework beforehand so that I can ask a question with value and not bother those people with asking about "babbies first irradiation" level of basic information.

What got you into spaceflight in the first place?

>>14757980
What are the radiation particles, protons andor photons?

Why would the moving shields not work,
It's like foosball, if you just grab the sticks and move them back and forth, as opposed to leaving them stationary, when tossing the ball at the goal from every direction.

Like if there were 10 or so nesting concentric ovals around the ship, all rotating with padded space in between.

Can't prevent the Sun from shitting out flares and can't do anything to reduce cosmic radiation flux. The VA belts are the only thing that can be "drained" and they don't matter at all even before you're as far away as geostationary orbital altitude.

>>14758779
SpaceX has faced minimal issues with getting permits for non-orbital tests, the only major issue was getting a license for an orbital launch. Arkansas wouldn't help with that. All it would do is split up development between BC and another site and complicate logistics. And it'd make moving the boosters between the OLP and the highbays and working on them impossible, since they'd be in arkansas.

>>14759040
But why?

>>14759104
Too expensive to upkeep. They're getting a barge like SpaceX.

>>14759104
because it's a retarded design. they're doing either a drone barge just like spacex or only RTLS.

>>14759104
Turns out they didn't want to waste time/effort on $100 million dollar ship, when you could just do it on a barge landing like SpaceX did for what is essentially the cost of materials + labor

>>14759104
they bought it way too early before they had nailed down what they wanted it for and it turns out they don't need it

>>14759112
(the implication is that they will not be launching rockets)

>>14759107
>>14759108
Well that answers one of the whys, but why in Brownsville? The irony of that is beyond words. I'd think that would be the last place Bezos would have it scrapped even if he had to pay an extra hundred million just to have it not be there.

>>14759118
because brownsville has a major port with a lot of shipyards that can do it, presumably

>>14759091
they didnt think to like lease the damn thing when glenn got closer to reality? even funnier is I think Blue is contracting the same company as SpaceX for drone ships haha

>>14759131
i get the impression sometimes that 99% of /sfg/ posters care more about blue succeeding than bezos does. obviously they were planning on having new glenn flying by now but when his team told bezos that it was still years away he just accepted it and scrapped the boat instead of firing the dead weight and taking charge of the operation.

>>14759108
>RTLS
Any indication that they'll try RTLS? They probably could, but payloads light enough to RTLS the booster might be light enough to fly on cheaper rockets. BO also has the pad to the north of New Glenn's pad, and there's been some activity there lately, so maybe they could put a pad there.

>>14759142
for as big as it is new glenn seems to really underperform on its stated LEO payload. with something its size you ought to be able to RTLS and still get 50 tons to orbit.

>>14757563
Really all you need to do is create a magnetic field, earth's magnetic field does a pretty good job of protecting us already. It isn't even all that strong so I don't think it'd need much power.

Speaking of RTLS, are there any numbers on the payload difference between Starship with Superheavy RTLS and Superheavy landing at a downrange site?

There are many visual models of different things in the mathamatics and sciences, one of theoretical fundamental physics positions is to provide the appearance and understanding of Gravity (and Electromagnetism, among other things), 60 or so years ago the image of the 2d semi sphericle coordinate 4d graph space is shown.

60 years later has there been any progress on 4d depicting masses interaction with the gravity field (the Sun making the Planets orbit it). I have seen really good computer simulation, animation, 4d graphics in video and videogame and art, I bet it can be done if someone knows how to tell the computer graphic simulators what the math and observation say the gravity field is to be represented as in a 4d model as to cause the Sun to cause the Planets to orbit it

Guys whats the most exciting, impactful, giant leap event in spaceflight and rocketry by this time next year?
What's the biggest thing to look forward to the next year or so in spaceflight

SOLAR/BATTERY CHAD RISE UP

>>14759229
You might want to follow the response chain.

>>14759239
There was never an indication SpaceX will build 1 MW of nuclear power. Musk has stated in the past he will build MW of solar panels, over and over again.

if you're designing a solar-system-wide laser thermal propulsion network where would you want to put all your beams? i'm guessing sets of 4 in stationary orbits around all planets would be a must just for burning out of low orbit.
would sticking some in cycler orbits between planets be worth it to speed up transfers or would those be useless for non-hohmann trajectories?

We will mine uranium on mars far outside earther jurisdiction

>>14759232
We'll have to see what fuel they end up picking for NTP but they all seem to be targeting the same HALEU that everyone designing new reactors wants to use.

It's anticipated that demand will outstrip supply by 2030 unless something's done about it: https://www.energy.gov/ne/articles/what-high-assay-low-enriched-uranium-haleu

Elon said solar and nuclear.

How will long lasting long working ai robot builder drones be powered? And their thrusters?

Say 100 or 1000 robots are constructing a solar array energy to battery storage space factory, how are they and the eventual factory being powered?
And what is the deal with thrusters on the robots, that can only be a gas propellent method, solar to electric could never provide thrust for mechanic bot?

>>14759343
Yeah at dickshit concentrations - point to me where you'll find an unconformity, placer or granite-hosted deposits on Mars faggot. You'll have to process retarded quantities of regolith in order to get worthwhile quantities of uranium

>>14759366

>>14759377
He said solar and nuclear.

>>14759379
on Earth, not Mars.

>>14759376
It's underground retard. Some geologist you are, don't know how rocks work?

>>14759260
Fuel availability isn't what makes the prospect of nuclear power on Mars nonsensical, it's the mass, the cost, and the limited output of a single monolithic reactor that could fit within Starship or the immense challenge of building a reactor on-site.
>>14759250
Most planets don't have good cycler orbits, Mars is the exception. A laser thermal burn can be done in a single pass with just one laser ground array. For high delta-v and long duration transits, laser electric would be better, and those lasers should be located at a Lagrange point for constant beaming over months. Chemical propulsion would inject the craft into a higher energy orbit to decrease time spent spiraling out of the gravity well.

John Drury Clark's Ignition. It can get pretty technical but honestly you can just gloss over the technical terms and read the funny stories. Think of him like your crazy boomer uncle telling war stories.

>>14759496
As I understand it we're pretty sure that Mars has a pretty extensive cryosphere - which is basically analogous to groundwater on earth but frozen. It can get pretty warm on Mars during the summer (like ~20 ºC near the equator) - that coupled with any salt in the ice makes it not unreasonable to suggest that you could get some brief bouts of liquid water flow through and out the sides of any escarpments that cross the cryosphere table. Pretty sure there are lava tubes on Mars as well but who the fuck knows what's inside them, probably ice and feldspar

>>14759473
I've got a chunk of the Campo del Cielo and a slice of the Seymcham meteorite.

>>14759543
It's like Early Life but for rocketry

>>14759343
I went and dug up the Gamma Ray Spectroscopy paper - excuse the crap resolution - the author was a fucker who didn't include a good figure. You can see that Th concentrations barely exceed 1 ppm at best - and given standard association trends on Earth you can confidently assume that U concentrations will be even lower. Compare that to even the shittiest uranium ore deposits on Earth which will have hundreds if not thousands of ppm and the best ones which have ~10-30 wt%.

>>14759550
Might actually be a strat, I've heard more than a few stories of people ripping unreleased data from graphs

>>14759552
I'm pretty sure the GRS data are freely available for all, the paper just did all the legwork of interpretation - background correction etc.. Those stories sound pretty dreadful though. I think in this case it's more that they're a dumb boomer who doesn't know what a jpeg is.

>>14759473
No but I live near the proposed splashdown site of Starship OTF 1, so whatever happens with it I might be able to get in on the action. If it disintegrates on re entry, and pieces get scattered in the ocean, floating bits like the material between the hull and tiles will eventually end up on shore. I know it's a stretch to actually get a part in my possession but a man can dream

>>14759561
The one that comes to mind is https://www.universetoday.com/112008/are-the-bicep2-results-invalid-probably-not/

They took the data off a graph presented on a slide

>>14759566
Ahh, that doesn't seem particularly egregious but they probably could have asked the Planck team for the data and they'd probably have given it. It seems it was just needed for a correction so they could still have cited the Planck team, just write "in prep." when referring to the data lel.

Thanks, why didn't Juno directly launch?
If its because of fuel, will starship solve this?

why not

>>14760050
It takes twenty years, that's the issue. And once it gets there it won't have enough fuel to explore the system so it'll just be stuck in a high altitude orbit until it either dies (if it didn't already die on the way there), or it gets flung out of the system by a moon
Keep in mind that once the probe got the it would've been 40 years old

>>14760100
Pioneer 10 weighed just 258 kilos, Juno is 3.625 tons.
There's also the difference between Pioneer 10 being a flyby mission and Juno being an orbiter, Juno likely would've needed far more fuel to slow down at Jupiter if it was a direct launch

Not really, it has more delta-v remaining once reaching space due to the flight profile of Atlas and the high Isp of hydrogen fuel but a hypothetical Starship kickstage would use methalox to simplify the ground support equipment and to maximize the propellant mass that can actually fit in the payload bay.
>>14759851

A large crater on the moon?

Or maybe launching large number of self-assembling module on Starship?

Imagine launching 100s of 9 meter diameter dish just like Starlink. Each one of those modules would have individual maneuvering capabilities as well as capability to sync in a swarm. In case of damage to one of those module, the each module can be de-orbited and a new one can be launched. Modules will have millimeter level accurate actuators such that when one modules join another module, they can control the accuracy of the gap for a uniform level accuracy.

It would only cost SpaceX ~$4B to design/build/launch them.

Its such a tiny amount for a years worth of contract. Assuming each dish costs $2500 and they pay $500 per month, that's about 200 units of Starlink, assuming commercial rate. If there's business rate that costs double, then the unit could be 100.

>I'm certain a small nuclear reactor could be made in sections and shipped to mars.
It's not that easy, even on Earth the SMRs marketed as truckable would actually have onsite construction periods that span months. PWRs found on nuclear submarines wouldn't work for space, a high operating temperature is required to make the radiator size/mass reasonable and instead of a simple but massive steam turbine it would use a supercritical co2 turbine which in itself is a challenge to create. Will SpaceX spend tens of billions developing a multi-MW reactor for Mars that would be worse than solar in everyway that counts? No. Will a small 40 kWe Kilopower reactor be used for emergency power? Possibly but it's not required.

>>14760204
his whole argument is that spacex won't have enough demand for starship to launch enough to spread out the dev cost, but this ignores starlink launches, artemis launches, and the fact that SpaceX will be replacing commercial falcon 9 launches with starship launches

>>14756758
Galaxy brain idea:
Life is a Newmann probe / terraforming device. Life's goal is to terraform the host planet, produce an intelligent lifeform via evolution and have that lifeform colonize/terraform other planets. Once the lifeform's electromagnetic signature is big enough for the alien creators to notice it, it means it's time to wipe the main lifeform and take over the planets.

Sure, its now paying things off in dues, and in hindsight its worth it. But hindsight is almost always worth it. So it's revisionist faggotry. The lying to your face contradiction is unbelievable.

How much cheaper does sending shit to orbit need to be before we can send manufacturing into space? I heard the starship is supposed the drop the costs by ten fold but i don't know how much of that is true.

What the fuck are you even trying to say retard? Of course would need a lot less fucking delta V launching from the Moon than Earth.

It was the first manned mission to Jupiter, it didn't launch "From the moon", it launched from the construction facility where it was built in Moon Earth L2.
>Why there
In universe, engine development happens on the Moon because it's the only place with enough room. Materials come from Earth, there is a large base on the Moon to support large scale manufacturing and they have large stores of Helium-3 for fuel (It has a fusion drive)

>>14760693
Planetes is also the single most /sfg/ piece of fiction to ever exist.

>>14760693
take the Farquhar pill

>>14760450
Earth-Moon L2 to escape dV requirement: 440 m/s
LEO to escape dV requirement: 3210 m/s
>Goal is to have <2 year trips to Saturn.
Not really achievable with chemical propulsion and an orbiter mission would be way slower, it would likely use electric propulsion so rather than the difference in delta-v being that impactful, the main advantage is that it would spend far less time spiraling out of Earth's gravity well.

That's dumb.

Nope.

>>14760494
that's for l4/l5 where you can't take advantage of oberth at lunar perigee on your trip back down into earth's gravity well. l2 will save you like 500 m/s over that.

Wtf??? We're letting Elon launch valuable US assets now? How many people did he bribe to get this sweetheart deal, this is so fucked. All his rockets do is BLOW UP!!

It's not so much cheaper than reliable and practical as well, many corporation wouldn't mind paying million per launch if they new they could do it anytime, reliably. Being able to assemble stuff in space without needing 8hours EVA but with remote-robots would also be necessary.

Then you need some actual market, a reason to send stuff up there. SpaceX is trying to create it with Starlink subscriptions to found whatever they do at a loss.
If we can get the mining industries into it they would insist on space-dock and robots ship, doing it cheap and efficient instead of boasting with manned flag delivery mission.

Why the fuck did Russia fumble their space race lead so bad?

incredibly underrated orbit

>>14760856
Couldn't sustain it. Couldn't sustain development speed and cost.

Same reason Boeing/Lockheed/Grumman cant compete against SpaceX.

>>14760880
Is this the Chinese station? Looking pretty good.

>>14760883
correct

It's already over, the Uranus Orbiter and Probe will be powered by three shitty RTGs instead of solar array or a fission reactor. I'd post the PDF but the file is 10 megabytes and I'm too lazy to resize it. It's the last one here

you're a bonerfied retard

>>14760909
Why are you upset?

>>14760906
Mate fission reactors have expensive r and d. RTGs aren’t as good but are cheaper

>>14760928
Or NASA should just stop prioritizing low power limited science missions. Kilopower will already be developed for Artemis, the issue isn't cost it's reliability. Despite the conservative mission profile, JPL will get billions and they'll still manage to fuck something up.
>>14760933
What specifically?

>>14760856
The only time the USSR was ever in the lead was right at the beginning. They all thought Kennedy’s moon challenge was just political bluster so they played their petty politburo games and let NASA build up its lead in heavy-lift rockets. The R7 was an exceptional starter but even the Molnyia couldn’t do much past LEO. The Soviets didn’t get ANY real heavy lift capability until the Proton in 1967. By that point America already had the Titan IIIC, Saturn IB, and was just eight months away from launching the first Saturn V, while the N1 was still 15 months out from its first explosion.

also nuclear costs too much.

>>14760972
It’s decently possible

>>14760961
Not really, the reason was because they only looked at rockets through a military perspective and had little interest in pursuing unneeded heavy lift capabilities. Only reason UR-500/Proton even got approved was because it was pitched as a TSAR bomb ICBM. There was no real drive to actually land a person on the moon from the people in charge, hence why development of the N1 only got approved right before Kruschev got ousted and why the development started in late 1965 on a pathetic budget being spread over several design bureaus, that only got funding approved by doing the same ICBM pitch.

The Soviets never saw it as much of a race with the US to the Moon. They didn't care enough to put any real effort into it like the US did. They were happy with the propaganda wins they were able to manage and were mostly interested in military applications.

Agreed, so RTGs should be off the table

>>14760715
your soul is weighed down by gravity, please watch all four hundred episodes of Universal Century Gundam in order to understand /sfg/

RTGs are not nuclear and are 1000x cheaper
