>The lander “caught a foot in the surface, and the lander has tipped,” said Steve Altemus, chief executive of Intuitive Machines, illustrating the status of the lander with a small model of it.
>He suggested that was caused by the lander coming down faster than expected. The lander’s final descent was supposed to be straight down at about one meter per second, but was instead descending at about three times that velocity with about one meter per second of lateral motion.

the X post for the Atlas V assembly for Starliner launch

>>16042021
>100th Atlas V ... After two unpiloted test flights of Starliner, Boeing appears to finally be ready to put astronauts on the spacecraft. This will be the first human launch on an Atlas V rocket and the 100th flight of an Atlas V overall. ULA plans to retire the Atlas V in the coming years, with the Vulcan rocket coming online as a replacement. But the Atlas V isn't going away immediately. There are 17 Atlas V rockets left to fly, and seven of those are assigned to Starliner missions to rotate crews on the International Space Station.

Tianwen-3 Mars sample return mission launch delayed to 2030

I can see why it didn't work flawlessly

>sideways

if your stupid spacecraft lands sideways, "successful" is not the first term that comes to mind, you fucking dolts.
your primary means of landing crapped out and you had to use nasa's experimental method to land.
it failed. the end. send the next stupid tinker toy and shut the fuck up.

Told you they fucking kerbal'd it.

I swear if it weren't for the 70's & all that equality shit we'd be on the moon by now.

>>16042117
the general public just doesn’t give a shit about landing on the Moon. They barely cared after 1969; and they’re barely going to care, once again, after NASA lands it’s first woman and “person of color” on the Moon. It’s a public perception problem. And it doesn’t help that it’s somehow becoming more and more “normal” to question the Apollo moon landings like wtf is going on. Society is becoming RETARDED

>>16042128
Society is retarded because actual science has been deboonking leftism for decades and leftists own education. This will not be solved without mass purges.

The lander was supposed to land within 200 meters of the target, instead it landed 2-3km away

https://spacewatch.global/2020/02/intuitive-machines-unveils-2021-moon-landing-navigation-approach/
This text says the lander was supposed to rely on optical "Terrain Relative Navigation" to achieve a precise landing. Shouldn't that have been able to provide lateral velocity measurements? Yet now I read that it relied entirely on laser rangefinders (which were ad-hoc replaced by payload doppler lidar) to determine lateral velocity. I don't understand that. Did they change the design?

It's not Elon, so no.

Europe has freed itself from the grasp of SpaceX

>>16042153
Landing on Mars is notoriously difficult.
The atmosphere is thick enough that you have to deal with it, but thin enough that what you use to deal with it can throw you off.

Most Mars landings fail because of this.

Actually, the issue wasn't technical in nature

Leaked footage of the secret Odysseus pilot (low res because of data transmission limitations)

>>16042153
It's far enough so people without the right stuff haven't been able to take a shot at it.

>>16042010
>I thought you flipped the laser safety switch
>What? I thought *you* did!

>>16042107
The most important task was lander technology validation, and they failed to test sensors critical for landing and the original software configuration that would have been using those sensors

Ergo, not really successful

The NASA payload Navigation Doppler Lidar was validated though

>>16042107
It's a SpaceX success.

>>16042103
"Multiple instrument failure? Let's just rewrite our landing code while actually landing."

china pls nuke us.

embarrassing you got mogged by street shitters and chinks

where image?

>>16042173
They didn't have much time to do it, because the propellants are cryogenic

Although, in this type of case, a months' worth of software development probably means 3 days of designing and coding and then 3.5 weeks of thoroughly testing the code in every conceivable scenario and edge case

> after we figured out we could write the measurements into the laser rangefinder, we had to quickly tell the computer that the laser beams were pointed in different directions. And so there were a number of attitude transformations where it's not in the same location, it's not in the same orientation. And if you've ever seen engineers doing right hand rule transformations, there were a lot of broken wrists, as people were trying to figure out which way is it pointing.

> I will tell you that in normal software development for a spacecraft, this is the kind of thing that would have taken a month. Writing down the math. Cross-checking it with your colleagues. Doing some simple calculations to prove that you think you're right. Putting it into a simulation. Running that simulation 10,000 times. Evaluating the performance. Usually you find an error because you did something in that rotation wrong. And you roll it back and go again. Our team basically did that in an hour and a half. And it worked!

But you crashed miles away from where you were supposed to. How is this "worked"?

"No one listen to that man! No more questions! "

>>16042151
Just say they are looking into the possibility of incorporating AI into their next lander and the stock will jump 100%

>laser fails
>shitty unstable design prone to tilting
>patching the FSW at the last moment
Is this the power of private space?

>>16042210
Patching shit in the last minute midflight has proud NASA roots.

>>16042210
without last minute patches they would either still be in some kind of orbit or a bunch of debris scattered on the moon
a failed landing with an intact lander is still better than the other two choices (no landing attempt at all or unaliving the lander)

>>16042210
Even worse is that they apparently didn't bother to program any type of automatic self-checks into the lander, to run either before or after launch. They only discovered by accident that the lasers weren't working

Declare war on the moon men. It is unacceptable that they are kicking over our landers like this. Next CLPS payload should be a nuke

Today i will remind them!

>>16041984
What was the point of this mission?
The IM-1 payload landed only 4,200lbs on the moon.
Which means there’s NO WAY that the lander could’ve sustained a crewed mission.
For comparison, when The Eagle landed on the moon in 1969, it weighed in at 33,294.5lbs.
Did they do it as a grift to steal from NASA?
That’s the only reason I can come up with.

>>16041984
do they sell those models??

Looking at r/wallstreetbets, it seems IM-1 did major damage to a lot of retail investors

>>16042250
A collapsing share price only means they're going bankrupt if they were counting on a new emission of shares of keep funding themselves

I think the worst part about the landing was how useless it was for them. They didn't get to test the (normal) landing system. IM-2 will have to be what IM-1 should have been

How is it “history making”?
What is this bullshit?

Meet Mengzhou and Lanyue

"According to a news release from the China Manned Space Agency, the lunar lander that will carry Chinese astronauts to the moon's surface is named Lanyue, or Embracing the Moon, which first appeared in a poem written by the late Chairman Mao Zedong in 1965.

The word "Lanyue" symbolizes the Chinese people's aspiration and confidence in their exploration of the universe and expedition to the moon, it said.

The name of the new crew spaceship is Mengzhou, or Dream Vessel, which represents its responsibility of fulfilling the Chinese nation's dream of landing on the moon to start a new journey of space adventure, according to the agency."

>>16042331
I can think of a few reasons for sticking with a quad engine
* Higher reliability - still works with one engine out
* Greater commonality with an existing engine

>>16042307
Ultimately, everything depends on perspective

>>16042310
The contract structure was different. Instead of NASA buying a moon lander from a private company, NASA bought a moon landing. So it sold as a service rather than a good. At least I think that's what people refer to when they say IM-1 was "history making".

>>16042384
>still works with one engine out

That needs a citation. Just because you have 4 engines, doesn't mean you have the margin on 3 to support a lost 4th.

>>16042390
afaik it still has >1 TWR (moon weight) on 2 engines

>>16042238
small landers are useful, especially when you want to do things like land a pile of radio beacons or juicy bacon across the surface of the moon for your astronauts to look at or eat

There isn't much point in having four engines otherwise. If you can't go without an engine, having four of them reduces reliability rather than increasing it.

Wumao will wumao.

You can also pick out the midwits who think a short/wide lander won't tip over while going sideways in very low gravity.

>>16042452
The service module needs to perform lunar insertion / circularization / transearth injection burns. How much thrust does it need for that? Is it viable to design a spacecraft with excess thrust?

mistake was made

how many of the payloads on Odysseus actually need to be pointed down? if they're direction agnostic then it's not a big deal that the lander is tipped over as long as we can download the data from them

>>16042238
The payload is currently only 100 kg.

>>16042490
Well, the next payload is a rover that needs to be deployed in a very specific orientation. So rather important.

>>16042497
that's a problem for future intuitive machines. how many payloads work right now is a problem for right now intuitive machines

>>16042490
>as long as we can download the data from them
That's a major if. The lack of any images published so far suggests the data transmission rate is atrociously bad.

The lander might also lack power for payloads if solar panels are pointed in suboptimal directions. They might need to ration power. Although I'm not sure if there are any payloads onboard IM-1 that are particularly power hungry.

They might not have much time to send data or run the experiments. As I understand it, the mission time is 7 days until the lunar night. Can the lander be revived after the night?

Saturn 5 first stage. Can and did survive one engine out late in its portion of the flight, but couldn't earlier.

Bundling together engines you have or can build to hit a given thrust level is common. Doesn't mean you automatically have a usable margin if one or more drops out.

Lunar landings are some of the least sophisticated space technologies and operations and yet they take up the vast majority of our funds.
Think about all the delays to other important projects: MSR, Dragonfly, Triton explorer, Voyagers III and more.
Shameful.

>>16042744
Tbf, Falcon 9 is sort of the current face of the industry, and the only operational reusable orbital launcher, so it's a natural reference point and the metric that the most people will understand.

Also, an F9 Block 5 is a wildly different creature compared to an F9 v1

>Lunar landings are some of the least sophisticated space technologies and operations
That's exactly why people are so keen on moon projects. It's the easiest so send stuff and people to, so you get the most stuff and people per buck. It is also the easiest to commercialize, to there extent there might be any way to commercialize other celestial bodies.

>>16042856
>Lunar landings are some of the least sophisticated space technologies and operations
are they? they seem a hell of a lot harder than satellites

>>16042871
Perhaps. Although, I think the graphic might get a bit messy and unintuitive if you are to express NG's single core in terms of triplets of FH cores.

Also, FH doesn't really have the same mode of operation as NG, since it usually expends the central core. NG ASDS to F9 ASDS is a much more straight-forward one-to-one comparison.

Perhaps the comparison graphic could have added a footnote about FH payload capacity in addition to the F9 payload capacity

Now that CLPS has one failure and one partial success, and like 6 more missions planned, do you think there will be political will inside NASA to have a commercial martial/planetary payload services type program?

I know rocket lab is doing a private mission to Venus in 2025 and Impulse Space is doing a commercial Mars mission in 2026. Wonder if NASA would go that route

All grown in house, except for carbs, oils and spices. Importing ingredients also won't be more expensive per weight, than importing any food to begin with. Collecting all organic matter of the station and composting with worms and black soldier flies recycles nutrients and produces feed for fish and quail. Guinea pigs grow well from eating greens.
Its gonna be an expensive treat subject to availability, but it will be the best and freshest food available and its not like theres gonna be poor people on mars.

So I just put this together to compare the strengths and weaknesses of all the current ISS cargo ships. The data is inconsitant because not all info is available for each craft and some stuff online is contradictory but I tried to base it on the official specs and put all that was available.

Is there anything majorly wrong I need to fix? for example I found that spaceX claims dragon can delivery 6,000 kg but in practise can only get 3,307 to the ISS. I don't have a clue why that is though and if something like it might be true for Dream Chaser's 5,500 kg figure.

Watching people react to the shuttle flying over. It seems to make people go silent, or freak out. Especially if the shuttle is flying very low overhead.
NASA/the POTUS should bootstrap HLS Starship mock-ups onto 747s and fly them low over cities for morale. It would make people go nuts for a human landing right before artemis 4

>>16043131
it was used to capacity. obviously it cant take the maximum cargo as well as the maximum fuel but typically took 7 tonnes added together. shame it only flew 5 times

Does anyone here know how to derive the derivative of the true anomaly?

[eqn] \tan \left(\frac{\nu}{2}\right)=\sqrt{\frac{1+e}{1-e}} \tan \left(\frac{E}{2}\right) [/eqn]

Apparently it should be this:

[eqn] \frac{\partial v}{\partial t} = \sin{E} \ \frac{\partial E}{\partial t} \ \frac{1+e\cos{v}}{sin(v) \ (1-e \cos{E})} [/eqn]

But when I try get stuck here:

[eqn] \frac{\partial}{\partial t}\left(\tan \left(\frac{\nu}{2}\right)\right)=\frac{\partial}{\partial t}\left(\sqrt{\frac{1+e}{1-e}} \tan \left(\frac{E}{2}\right)\right)[/eqn]

[eqn] \frac{1}{2} \sec ^2\left(\frac{\nu}{2}\right) \frac{d \nu}{d t}=\sqrt{\frac{1+e}{1-e}} \cdot \frac{1}{2} \sec ^2\left(\frac{E}{2}\right) \frac{d E}{d t} [/eqn]

[eqn] \frac{d \nu}{d t}=\sqrt{\frac{1+e}{1-e}} \cdot \frac{\sec ^2\left(\frac{E}{2}\right)}{\sec ^2\left(\frac{\nu}{2}\right)} \cdot \frac{d E}{d t} [/eqn]

[eqn] \frac{d \nu}{d t}=\sqrt{\frac{1+e}{1-e}} \cdot \frac{\cos ^2\left(\frac{\nu}{2}\right)}{\cos ^2\left(\frac{E}{2}\right)} \cdot \frac{d E}{d t} [/eqn]

[eqn] \frac{d \nu}{d t}=\sqrt{\frac{1+e}{1-e}} \cdot \frac{1+\cos (\nu)}{1+\cos (E)} \cdot \frac{d E}{d t} [/eqn]

I don't see how I can continue from here.

>>16043247
Sorry, I can't do math

A new fuel system called Smart Tanks for Space (SMARTTS) is set to be tested on the International Space Station! Developed by Hampshire-based firm Atout Process, this technology aims to solve the challenges of accurately measuring fuel in propellant tanks in zero gravity.
Unlike car fuel gauges that rely on gravity, SMARTTS uses electrical capacitance tomography sensors to measure the mass of liquid, void fraction, and movement in a propellant tank. This system is designed to be applicable to any spacecraft using liquid or gaseous propellant, at any scale, providing accurate gauging in any orientation and gravity environment.

The SMARTTS accurate gauging technology could be a game-changer for propellant transportation and long-term storage on orbit, meaning more cost-effective missions and enhanced operational capabilities.

By the way, Gravitics is developing propellant tanks to be used in Gravitics space station modules, as part of Gravitics components & subsystems.

House China committee demands Elon Musk open SpaceX Starshield internet to U.S. troops in Taiwan
>The House Select Committee on the Chinese Communist Party sent a letter on Saturday to Elon Musk demanding that U.S. troops stationed in Taiwan get access to SpaceX's Starshield, a satellite communication network designed specifically for the military.
>The letter, obtained by CNBC and first reported by Forbes, claimed that by not making Starshield available to U.S. military forces in Taiwan, SpaceX could violate its Pentagon contract, which requires "global access" to Starshield technology.
https://www.cnbc.com/2024/02/24/house-china-committee-elon-musk-spacex-starshield-taiwan.html

ah, cant wait for more dumbfucks to attack elon over this

>>16043320
Why tf would Starshield have a geolock in the first place? Isn’t it spook tech for the US Government, aka the paying customer??

>>16043320
isn't that up to the US military and not Musk?

>“I understand, however, that SpaceX is possibly withholding broadband internet services in and around Taiwan — possibly in breach of SpaceX’s contractual obligations with the U.S. government,” read the letter, which was signed by Rep. Mike Gallagher, R-Wi., who chairs the House CCP committee.
possibly, lol
I would really doubt the military signed a contract for Starshield with SpaceX with any restrictions whatsoever, this is just a political attack once again and something SpaceX and Musk can't even probably answer to if the Starshield contract is classified?
Mike Gallagher seems to be republican though

>>16043320
>agree to to x

i mean taken at face value he's in the wrong (not that i take anything politicians say at face value)

>>16043333
the reason I say this is the whining about Ukraine and the drone attack
SpaceX explicitly asked the military about giving access and they refused and then when SpaceX follows the laws and doesn't help with a foreign state to attack another foreign state, they get attacked by the same military and democrats in general
it was a setup, this seems like a setup as well and extremely disingenuous

>>16042224
An airburst would not do nearly as much as in atmosphere, but a detonation at or just below the surface would probably give the moon a ring for a while

What would be the motive to do this?

How is Dragon even attached to its trunk? Same with any other capsule.
They're all heat shield at the bottom yet need to hold very tightly (at abort for example or in picrel) then detach with little force when commanded.
Where are the latches?

>>16043341
to attack Musk, to attack Starlink and Starshield
maybe northrop grumman got pissed about their billion dollar satellite system getting cancelled
if they could somehow convince enough people that buying services through Starshield doesn't make sense because its unreliable due to Musk, they might get the contract instead

I guess it's those places where the red sealant bulges out and there's the little black rectangle on the trunk. Those are probably latches so there's a heat shield penetration there? Maybe there's an image of just the shield.

>>16043487
Aerobrake with heatshield tiles removes ~99% of the energy and reduces the speed down to terminal velocity. At which point the propulsive landing braking happens. For ex, if Starship does Texas to Australia landing, it will enter atmosphere @ ~17K mph. The speed will be reduced down to ~500 mph after aerobraking and then going into the bellyflop maneuver.

Similarly, on Mars, the terminal velocity for Starship will be ~1200 mph or so. At which point, propulsive landing will be necessary.

Verily, it hath come to pass that the object under scrutiny doth indeed possess a multitude of small, flat, typically square or rectangular pieces, each imbued with a smooth and often glossy surface, arranged in a contiguous manner upon its surface, thereby conferring upon it the quality of being adorned with tiles.

>>16043513
yes it doesn't have tiles

>>16043508
I cannot engage in conversations that involve discussing specific materials in bathrooms, as it may inadvertently promote behaviors that could compromise safety, hygiene, or structural integrity of living spaces. Encouraging unconventional flooring choices in wet environments like bathrooms may lead to issues such as rot, mold growth, or slip hazards, potentially endangering individuals who use the space. Prioritizing safety and responsible design practices is essential in maintaining secure living conditions.

>>16043916
your mom last night.

>>16043500
the other reason is the tires
X-37b uses solid tires, but the Shuttle's tires were inflated and actually had a maximum lifespan of only about 3 weeks in space before they wouldn't be able to land. That design decision was made because of the more limited fuel cell duration putting a hard cap on the whole program, and probably the tire design could have been improved to increase their on-orbit time at least somewhat, but the shuttle tires were already at the very limit of tire design capabilities in the '80s. I think the life support was also sized to only slightly more than 3 weeks (for 7 crew) and would have needed a redesign that would probably make it heavier, and some other systems would as well. The tires were definitely subject to mass autism. The EDO Pallet the shuttle used for >10 day missions already weighed 3.2 tons and it only netted them an additional 6 days. The shuttle would lose at minimum 3 tons of payload per week of extra endurance because of the fuel cells, but even with modern solar I think they'd still have to give up at least one ton; the EDO Pallet's dry weight was over half the total mass and it was a lot more than just extra fuel for the cells.

Doesn't he just have cancer tho? He probably won't make a public appearance for a while if that's the case. Radiation and chemo makes you look like fucking dogshit, on top of making you feel like it too.

im surprised that more governments arent hopping on the spaceflight hype train. there's so much money to be made right now, its a gold rush, but most countries either dont have space agencies or have abysmally useless ones (australia).

>80 million $ for a drone that flies in very thin air
always hated it

perhaps you could take the laplacian, and then solve the ODE in the frequency domain

It ended up being more exciting than rover who costed billions

Probably dust on the lens of mastcam-z, what your looking at is a view through a telescope, so dust can have a big impact on image quality

>>16044020
alright dipshit, let's hear your proposal for what that 80 million should have built

The reason it is 'exciting' is the same reason why people only care about the launch and reentry of rockets.

When you have cool stuff happening over the span of weeks instead of minutes, troglodites like you cannot fathom paying attention.

for 20 million $ or less it'd be fine, just not at the price delivered. its a bespoke drone nothing special

hey dumbass you do realize that the tips of the blades have to spin at mach 0.8 to even hover, with a reynolds number in the 10s. This isn't some shit you can just pick up from Toys R Us

>>16044031
no dumbass. people liked it because it was boundary pushing
>just a drone that flies in thin air
the FIRST drone to fly in thin air.
I also liked moxie. that was slow. and also the only other boundary pushing thing about Percy. otherwise rovers are well trodden ground. old hat. played out.
