around the launch site or where?
starbase has 3 major sites that are kilometers away from each other
the launch site, the factory site (which has employee housing and other random shit next to it) and masseys test site where they do cryo tests now and will do static fires soon
they built some retaining wall around the launch site, but I kind of doubt they are going to build it all around

I guarantee that thing could still fly but nasa is filled with PUSSIES who are terrified of the idea of pushing the envelope.

>>15995614
Even if it did fly I doubt they could control it.

>>15995614
nah this time it wouldn't work, shit would probably not even take off, they barely managed it with the current setup as is

the back fell off

Thought so.

>IVO CEO (Richard Mansell) claims that E Labs (a reputable testing company) validated his rocket engine’s thrust.
E Labs (link below) only says that they did “durability testing” which I believe involves subjecting the engine to vacuum and temperature ranges. (1) This whole space feels like the cold fusion nonsense. (2) If you read Mansell’s twitter feed – he sounds remarkably similar to Elizabeth Holmes. He mostly responds to cheerleading comments, but not to specific questions. Fact: The “IVO Quantum Drive” was placed in orbit on November 11, 2024 and yet here we are 10+ weeks later and he is tweeting about/promoting a children’s book he wrote a decade ago.

>He is also evasive about investors. Note: They MUST be investor funded since they have no products/revenue streams. And for a tech company their website is a joke – it has nothing of substance on it. IVO was founded back in 17 or so to provide “remote” charging tech.

That is pretty sus

>>15995604
I’ve only read headlines, not detailed articles or anything. Does NASA have a likely cause for the damage? I guess it just stressed / strained itself one too many times? Or did it land too hard on a rogg or something lol

>>15995638
it's over

https://arstechnica.com/space/2024/01/nasas-mars-helicopter-has-made-its-last-flight-above-the-red-planet/
> One week ago, during a simple hover test flight, NASA lost contact with Ingenuity for several hours. This is when it apparently broke one of its four blades. Later, mission operators restored communications by asking the Perseverance rover to perform long-duration listening sessions for Ingenuity’s signal.
> Before that flight, on the helicopter's 71st flight in early January, the helicopter was supposed to traverse a long distance of nearly 1,200 feet (358 meters), reaching an altitude of 40 feet (12 meters) and spending nearly 125 seconds airborne. NASA had sought to reposition the helicopter for future flights to survey new areas of the Martian surface. However, during that flight, Ingenuity made an unplanned early landing.

>>15995643
https://spacenews.com/ingenuity-mars-helicopter-mission-ends-after-72-flights/
> “Whether or not the blade strike occurred, which led to the communications loss, or there was a communications loss and a power brownout which then led to the rotor strike, we will never know,” he said, because of a loss of data during the incident, but added that the project team would try to piece together their best guess of what happened with the data they do get.
> One possibility is that the featureless terrain that Ingenuity was flying over may have confused the helicopter’s navigation system. Such systems work by tracking features on the surface and correlating them, throwing out spurious ones. “The danger is when you run out of features, you don’t have very many to navigate on. You’re not able to establish what that consensus is and you end up tracking the wrong kinds of features,” said Håvard Grip, the “pilot emeritus” for Ingenuity, on the call.
> In such a scenario, he said, the helicopter may think it’s moving horizontally away from its target landing site and overcorrects. “It’s likely it made an aggressive maneuver to try and correct that upon landing, and that would have accounted for sideways motion and tilted the helicopter,” he said. That could either have caused a blade to strike the ground or to lose power before landing.

so the problem may have been with the navigation system getting confused by a featureless landscape and faceplanting due to that

https://arstechnica.com/space/2024/01/a-japanese-spacecraft-faceplanted-on-the-moon-and-lived-to-tell-the-tale/
> But at an altitude of around 160 feet (50 meters), something went wrong with the spacecraft's propulsion system. Less than a minute before touchdown, one of the engines suddenly lost thrust, and moments later, a down-facing navigation camera caught a glimpse of what appeared to be one of the engine nozzles falling away from the spacecraft. JAXA said engineers believe the engine failure was likely caused by "some external factor other than the main engine itself." Officials are still investigating to determine the root cause.
>The spacecraft continued descending on the power of its remaining engine, but it became more difficult to control the lander. The thrust from the single engine imparted a sideways motion to the spacecraft. Normally, SLIM would have used thrusters to tilt itself from the vertical orientation necessary for the final descent and into a position to plop itself on the lunar surface along the spacecraft's long axis. SLIM had five crushable landing legs to absorb the force of the gentle impact.

For many years, across multiple administrations, Pentagon officials have lamented their inability to share information with other countries and commercial partners. Inherently, they argued, this stranglehold on information limits the military's capacity to connect with allies, deter adversaries, and respond to threats in space.

With a planned launch in 2031, EnVision is expected to conduct an in-depth study of the planet from its inner core to its upper atmosphere with the aim of providing a holistic view of the planet’s history and climate. The mission will include contributions from NASA, with the agency supplying a Synthetic Aperture Radar and Deep Space Network support for critical mission phases.

> - The Texas Parks and Wildlife Department (TPWD) has delayed today’s vote on the proposed land swap SpaceX requested for 43 acres of Boca Chica State Park to expand Starbase in exchange for giving TPWD 477 acres SpaceX owns near the Laguna Atascosa National Wildlife Refuge. The environmental group Sierra Club sent a letter stating, “… we don’t believe TPWD followed code in the way it provided the public with notice about this controversial proposal. The agency also failed to provide public notice in Spanish and in Spanish-language news outlets...” Cameron County Judge Eddie Treviño, Jr. was also critical of the land swap. The discussion is now scheduled for the 27th of March and the commission meeting is the 28th. I highly encourage everyone to go to the TPWD website and voice your opinion.

could scientists use starlink in some way as a ghetto inferometer? starlink satellites are linked together by lasers just like LISA will be. yeah LISA is millions of km apart, but LIGO is just 4km apart, which is far less than the 3000km apart that starlink is.

>With more than 8,000 space lasers across the constellation, Starlink satellites are able to connect thousands of kilometers apart, beyond the view of ground stations, and maintain pointing accuracy to enable data transfer up to 100 Gbps on each link
https://twitter.com/Starlink/status/1706719043460514101
https://en.wikipedia.org/wiki/LIGO

What if all anti-SpaceX troons were just thrown into the vacuum of space

>>15996073
I think there was some research about this recently, some german paper or something that would use LEO constellations to passively do something

>>15996073
No, there are no optics for interferometry. You also can't do it computationally as there is no phase information in whatever sensor they use. It's also difficult, LISA has to compensate for the pressure of the solar wind to keep its test mass on a drag free orbit. Obviously something starlink couldn't do, they don't even have test masses. They also dont use reaction wheels to avoid disturbance.
Gravitational waves is the ultimate autism, everything needs to be near perfection. There are groups who work solely on just sticking bits of the optics together.

>>15996095
Shut the fuck up chud

>>15996073
I don't think that's possible; the way a gravity wave interferometer works is shining laser beams down fixed distances to produce an interference pattern. Gravity waves minutely change the lengths between those fixed points, which changes the interference pattern in predictable ways. Without fixed reference points, you can't really build a gravity wave inteferometer.

OH NO-

Reminder that we predicted 3 years ago this drone will fly for years. It's so simple that it just doesn't have many failure modes. I remember an early press conference where the Indian that worked on the helicopter said it won't last long and that it could fail either because the springs in the legs could break or some solder on the chips inside could break.

door

>>15996416
If it hadn't chipped the blade on a rock it'd still be A-ok to fly today. What made it lose contact and come down hard in the first place, did Percy lose line of sight with it or something?

I firmly believe some type of flying drone will play a part in the future of Martian exploration. Also do any geologybros know if vegetation affects topography. Does it influence the shape of mountains?

>>15996421
Somewhat, vegetation does limit weathering.

>>15996423
Roots hold soil together, but also break up rock.

>>15996423
would there be any difference between south and north side of mountains since the vegetation of the norther side might grow slower(due to less light)

>>15996430
The sun shouldn't be a factor since it position in the sky changes over the course of the day and also because its not a point source. The big factor is the difference in rain as one side of a mountain chain is going to be in its own rain shadow, but that also depends on how tall the mountains are.

>>15996435
will different rain on the north and south side of the mountain cause topographical differences

The most interesting part is that it's CASIC doing it. Until very recently, they've only had a very minor role in the Chinese space program, and so far only in the niche of small solid-propellant launch vehicles designed for launching military reconnaissance satellites during wartime. That they're developing a medium-lift liquid-propellant reusable launcher suggests CASIC intends to partake in the Chinese space program in a major way, the way CASC currently is.

Maybe, but I suspect that rocket is simply intended to be a normal boring conservative rocket whose raison d'etre is that it's quicker to develop and field than a new reusable rocket while still being more cost-effective for Guowang/G60 launches than any of SAST's CZ-6/6A/6C are

>>15996489

>>15996491
Monocore XLV is clearly a job program and repurposing/consolation prize for losing the CZ-10 bid that may be slightly useful at gathering flight data for the YF100K before it’s used on CZ10, but it seems they still want to derive a multi core version out of it, if SAST really do dedicate themselves to it it may be worth reusing

Vulcan, Ariane 6, and H3 are all slightly more modern redos of the Atlas V/Delta IV, Ariane 5, and H-IIA, so it's a bit more like they're stuck in the very early 2000s.

https://spacenews.com/northrop-charges-on-lunar-gateway-module-program-reach-100-million/
> Northrop received a $935 million fixed-price contract from NASA in July 2021 to build the module, which is based on the company’s Cygnus cargo spacecraft. HALO will provide initial living accommodations on the Gateway and includes several docking ports for visiting Orion spacecraft and lunar landers as well as additional modules provided by international partners. It will launch together with the Maxar-built Power and Propulsion Element (PPE) on a Falcon Heavy.

https://spacenews.com/zeno-to-recycle-decades-old-radioactive-material-to-fuel-its-radioisotope-power-systems/
> Under the agreement with DOE, Zeno will have access to a large supply of strontium-90, a radioisotope created as a byproduct in nuclear fission reactors. The company will use the material to build radioisotope power sources, or RPS systems. These are compact devices that convert heat from isotopes into electricity. NASA for decades has used RPS systems for deep-space missions, but these systems are fueled by plutonium-238, an isotope that is in limited supply. Zeno designed an RPS system for small satellites fueled by strontium-90.

>>15996612
iirc its because Falcon Heavy is at its max weight limit with PPE+HALO

This launch contract was a mistake, 3m cuck modules and severe mass penalties, it should've been Starship or maybe Artemis II

Gateway itself was a "mistake" from an engineering perspective, but it might be necessary from a programme being kept alive/political perspective
perhaps it can be ignored after some habs get landed on the moon

https://payloadspace.com/firefly-aerospace-tapped-to-compete-for-us-spy-sat-launches/
> It has plenty of competition. Among others, the NRO contract has on-boarded Rocket Lab’s Electron rocket, SpaceX’s Falcon variants, and Northrop Grumman’s rarely flown Minotaur and Pegasus rockets; United Launch Alliance’s Vulcan rocket is likely to be certified as well. Virgin Orbit was a provider in the program, but SLIC’s first and only task order turned out to be Virgin’s last launch attempt, a January 2023 failure that teed up the company’s bankruptcy later in the year.

Interview with Dongfang Hours. Someone that covers the Chinese space industry specifically.

>>15996584
Is this why SpaceX boight a 737??

>>15996716
stopped watchin that dude after realizing it was just chicom propaganda and not an objective insight into their space program. disappointed

>>15996723
SpaceX buying 737 could be a sign that they're planning to utilize it more for large cargo. Possibly shipping starlinks/engines/etc.

>>15996727
what was it he said that made you think that specifically?

>>15996728
Maybe they are going to reverse engineer it andbuild the first true space plane

>>15996731
nice try, propaganda department

>>15996727
Sounds like a space fan that wanted to cover a niche topic.

>>15996584
their window of opportunity came and went
VTVL is the new meta

>>15996727
>>15996745
NSF is propaganda too. Good luck finding a critical take of SpaceX/NASA on there

>>15996728
what if they use it to carry starships to the cape, shuttle style?

>>15996184
just take a shower, the dangerous chemicals are all broken down or neutralized by water

As a so1boi I will not tolerate any criticism of SpaceX. They shit on SpaceX=I stop giving superchats

>>15996751
>critical take of SpaceX
there is no such thing; nothing to criticise

>>15996736
so you have nothing then lol

>>15996731
Mustve been something in one of these videos. Dont care to rewatch

>>15996325
oh is that Clear

>>15996770
are you sure it wasn't just describing what they are trying to do and it sounds too good to be true (like someone not awarae of space stuff listening to what SpaceX has achieved and is trying to do sounding like propaganda)

>>15996775
no it's a japan girl (18) who draws rocketgirls

>>15996782
I dont watch propaganda for the same reason I dont watch uninformative drivel, so there's no difference

>>15996787
you missed my point
a person uninformed with SpaceX achievements and what they are trying to do with Starship, i.e. demolishing and humiliating basically all of the worlds space industry, would sound like propaganda
but its true
just like the chinese actually developing falcon 9 clones very rapidly would sound like propaganda to someone being an US oldspace or europe space fan and more accustomed to their glacial pace

>>15996786
>starship is dark-skinned
Hnnnnnnnnn

>>15996820
Other rockets are usually mainly white, with black (or the case of SLS, orange) accents, while Starship is metallic grey and black, so this makes sense.

>>15996727
Dongfang is basically only good for giving interviews of chink companies that aren't too closed, otherwise it's really surface level.

He doesn't have the connections that could give some insight on the actual behind the scenes of chinese governmental and private programs, and he also doesn't have the sheer china-watching autism to make informed guesses over the continuous analyses of details over decades.

Still a decent digest for someone who's not interested in chinese spaceflight

As far as French Space-China-watchers are concerned, Phillipe Coué and East Pendulum are/were better

>>15996838
Dongfang is as close as a westerner can cover and probably one of the only covered source for Chinese space industry.

>>15996589
skill issue

>>15996852
World is more interconneted, DF is a Frenchman+HKer, a HKer and a Westerner could easily have better mainland sources.

Also autistic china watching still works, just like it worked for decades, just like autistic soviet-watching worked in the 70s/80s

>>15996913
Russia tried to sell China the RD-180 back in 2015 after they got hit with the first round of post-chrimea sanctions and it became clear that ULA wasn't going to be allowed engines from them in the future. China pulled some shit negotiations where they insisted they buy the tech needed to make the engines themselves instead of just making a few bulk purchase. Russia didn't like that deal any better than they did when Aerojet Lockheed made it back in the mid-nineties. It didn't help that China's half of the deal (selling Russia space-rated electronics to replace the ones now blocked by western sanctions) all turned out to be trash.

There's a possibility that they might sell some RD-191Ms to India for use on the kerolox version of the LVM-3, but it looks like ISRO is committing to get the NGLV out to the pad as quickly as possible, so the window for that partnership is pretty slim. There's a chance they could sell some RD-275s to North Korea for use on future versions of their rockets, but that's not a huge market either.

>>15996930
>>15996913
Everyone realized that multiple cheap engines >>> sophisticated engines
1 set of RD-180s can go on a 3.8m diameter first stage... but you can just use 9 200k lbf engines, lol

>>15996939
Actually, the 2016 version of the Long March 9 would have used 12 RD-180s.

What's the point of the second tower?

>>15996969
flexing on the FAA

>>15996969
Virtually no point

>>15996969
Launch cadence, the ability to do work on a tower and continue launching, an oopsie during a landing will not halt launches.

>>15996969
So if they blow up 1 of them they aren't set further behind

>>15996969
They legally cant launch from the second tower, and only 5 launches per year allowed anyway because the sound is too loud. the foundatation for a new mount would take 2 years to settle concrete anyway, just like before, and at least another year to outfit the mount. it's a 4 year process

>>15996983
Does it really take 2 fucking years for the concrete to cure?

Bong anons this is your chance
https://twitter.com/TypeForVictory/status/1750794122242166941

>>15996983
getting the license for another identical tower won't take as long, nor won't building it this time as they have experience with the previous one
they aren't building on the mudflats, but on the spot of an old suborbital pad so it will have settled ground already
and what the fuck are you talking about with 2 year concrete? lmao
it took maybe 3 months to drill and pour a new foundation for the pad after IFT-1, why would it take that much longer this time?
its going to take 1.5 years perhaps, not 4 and they can start doing some stuff in parallel

>>15995568
They should charge it to the max and then let it take off and look how high it can go before it rips itself apart with damaged rotors.

You start with "RD" which stands for "Raketnyy Dvigatel," or, Rocket Engine. Then you put a number after that. The numbers are vaguely sequential but don't follow any strict rules. Some numbers were skipped or intentionally picked because the designer in charge liked/didn't like them,

>>15997009
Only thing you need to know is that most of the people who developed those engines rotted away in some gulag.

SpaceX wasn't really "supposed" to win, the lander contract was supposed to go to a national team of oldspace contractors led by Blue Origin
but some people went rogue and picked it between administrations (it was clearly the best choice though)
Starship makes SLS look absolutely retarded, that is why oldspace and their supporters and cronies in NASA hate it and their supporters in congress
if it didn't exist, the SLS jobs programme could be kept running for much longer but now it risks being cancelled pretty early on after it is shown what starship can do and how cheaply

>>15997116

And that's just the rocket design, they've spent $24bn over the past 13 years meanwhile SpaceX has had to create a new rocket programme from scratch, new site, engines, tanks, FCS's etc... with only $5bn in less time.

And there absolutely is favouritism for old space at NASA all of the Gateway mock-ups show a BO HLS design, not a single photo on the sites images link shows SpaceX's HLS.

>>15997241
I think that dropping the Ariane 6 PPH was a mistake. A lot of the A6's delays have come from how badly Europe's let their liquid propulsion experience decay since the creation of the Vulcain. European solid fuel hasn't been the best lately but at least their skills are still reasonably current. A mostly solid Ariane 6 would have launched a lot closer to its original flight date.

.... you do realise PPH still used the Vinci+APU which is still one of the main cause of delay
Vulcan 2.1 was a relatively easy development compared to it
Now PPH (w/o A5ME, both being funded would be worse than A6) screwing over the whole Vernon-Mureaux astronautics jobs bassin from 2019 onward could possible have been beneficial if these skills - the main one in large cryogenic propulsion and Rocket structures in Europe - had been quickly reoriented toward RLV development, but that’s a tall order

they keep using that word, but the nature of a balloon means it will never actually leave the atmosphere, as in get above the karman line. Heck, 30km isnt even anywhere near the 50 mile NASA definition of outer space.
Virgin Galactic does the same shit.

WW3 is unlikely to happen anytime soon unfortunately. Just a bunch of small proxy wars.

>>15996523
>>15996538
What has it achieved so far?

>>15997377
Are we under two weeks now?

>>15997736
I wonder which two weeks is longer, IFT3 or the memedrive test?

>>15997724
First thing was proving that you could fly anything in that thin-ass excuse for an atmosphere.
It also did some aerial mapping that helped navigate the rover a little faster than the usual JPL standard speed.

>>15997724
The rover? almost nothing. drilled a few cores that will never return to Earth, it has no science payload on board so it cant do science. it hasnt taken any cool pictures like curiosity.

MOXIE made a few grams of oxygen

Now we have to wait for the Federal Building Agency license

i hate sounding rockets so much its unreal

Brainstorming ideas on how to make digging tunnels easier. Anybody got any ideas? Best I have come up with is a sort of water jet cutter that cuts up all the rock as it goes.

based retard. It has a neutron spectrometer for detecting subsurface water/minerals. It has a ground penetrating RADAR that can see layers up to 100 m deep. Also the all important weather instrument and other standard stuff. It has currently taken 327,304 pictures, many of which are cool.
but hey, the last year its mostly been travelling, it arrived at the foot of the delta jan last year and 1 year later it has reached the top already.

>>15997906
Reminder that we have heard almost nothing of the science that RIMFAX (ground penetrating radar) has done so for for unknown reasons. Perseverance also has a microscope and several spectrometers.

Dunno, Boring Company is experimenting with various techniques.

BIG NEWS

>>15996983
>only 5 launches per year allowed
It's been increased to at least ten

>>15997724
I'm pretty sure it's the only thing that's ever actually demonstrated ISRU

>>15997922
but why

We should focus on the Moon first.

>>15997927
So HWY4 won't be filled with hundreds of cars.

>>15997932
The moon is a distraction

The parking garage is at the production facility, which already has a lot of parking and where almost nobody parks on the side of the road. Further down at the launchpad is where the need a visitor parking lot

Just noticed that the Senator Administrator is a few days away from overtaking Bridenstine's term length

>>15997927
Probably so that they can free up other land for more productive stuff. They're clearly very limited on how much land they have.

Pamela Melroy is on CNN running her fat mouth and trying to blame all the Artemis delays on SpaceX.

Welcome to election cycles.

>>15997981
She's a NASA official in HEOMD so it seemed relevant.

>>15997909
>for unknown reasons
it's more likely that a bunch of geologists are bad at communicating their data, all of the data can be found using the analysts handbook https://an.rsl.wustl.edu/m20/AN/an3.aspx

>>15997909
I literally just saw some shit about that on twitter yesterday but scrolled past cause it was boring

>>15998000
Checked, no shit

>>15997993
looks like noise to me. Can anyone in the know break down what I'm looking at

>>15997910
looks retarded. looks like its taking a dump

>>15998005
A 2D slice of the Martian ground structure about 10-20cm deep, RIFMAX isn't that important but hey, geologists.

>>15997189
I miss this little beast

I need to know the history of Jezero crater bros

>>15998018
If reading obscure planetary science forums taught me anything it's that those layered rocks mean water.

>>15998018

>>15998021
it doesn't take a lot of looking to see river beds in and around jezero crater
