>>15157990

>>15157990
It took the right man for that to happen.

im surprised we dont have a time system yet for the moon. apparently we're working on it though and should have one in a few years.

>>15157992
>falcon heavy
>super heavy
>super
lifting a few more tons to orbit than F9 does not a super heavy make. learn the difference betweem heavy lift and super heavy lift or get off /sfg/

>>15157788

>>15158005
By American definition anything that lift more than 50 tonnes to LEO are super heavy lift rockets. Which both Falcon Heavy and SLS are above. By the Soviet/Russian definition it's 100 tonnes to LEO, which neither Falcon Heavy or SLS reach (64 tonnes and 95 tonnes to LEO respectively).

Also, boring as shit gimmick of a bait btw.

>>15158008
AAHHHHHHH THE FREENCHHHH

>>15158009
It should be ≥ 150 T from here on out

>>15158001
Probably because for 50 years, hardly anything was done with the moon, other than bouncing lasers off of a little mirror. Even when people did try to land stuff, it often just crashed.

>>15158008
Instead of calling people "gay faggoty retards" I will now use the more inclusive language of "people with gay, faggoty, and retarded tendencies".

Reminder SLS is such garbage fucking rocket that Energia, at half the fucking size, no upper stage and only meant to deliver payloads to LEO, has a higher TLI payload capability than it.

>>15158015

>>15158001
Not enough people there to warrant it. How did time work during Apollo? Was it some universal time or did they just go off of Houston time? I’m a fan of Houston time, it’s also Starbase time so it would work well if SX keeps mission control there for Starship stuff. And Artemis will probably be whatever Apollo used
>>15158008

>>15158054

>>15158030
it's called the Senate Launch System for a reason. not all congress, not the house, not the president. Bill led the team that decided what parts would be made in what states and by whom. He is the ultimate father and champion of SLS and no amount of revisionist history will change that

>>15157881
No this is their JPL separate proposal for NASA's bi/tri-annual lottery for who among their centers they get to pick next to fund a mission for that will take 10 years to develop (and better luck next time to the other proposals)

Isn't our space program just great

Bill Gerst of SpaceX says they’re hoping for the 33 engine static fire next week, but there’s still work to do

>>15157656
The truth hurts.

>>15157932
This image isn't to scale and it bothered me. So I did some calculations based on WA DC GIS data, latitude/longitude, pixels, and sheer autism, and determined the Wilbur Wright Federal Building is about 420 feet long, or a little longer than the height of a SS/SH stack, but shorter than the full height of the OLIT. Starship itself is only 160 feet tall, so it should be about half as long as it is in that picture to realistically appear to scale. You're welcome

"It's not well known that Skylab reached its orbital altitude with the expended S-II stage still attached. After 10 minutes, the S-II was separated and allowed to reenter the atmosphere. For that brief time on 14May1973, NASA had orbited a wet-dry workshop with 1,680 m^3 of pressurizable volume. The pressurized volume of the ISS is 913 m^3."

Cayambe is actually on the equator, not just close to it like Mt. Kenya. And there's this...
>Cayambe's peak is the point of Earth's surface farthest from its axis; thus, it rotates the fastest as Earth spins.
And Ecuador is more politically stable than Kenya but obviously if we're restricting sites to Africa, it doesn't qualify. Cayambe being volcanically active in recent memory is kind of a downside.

Why the fuck would you build a space elevator in a mountain anyway?

>>15158147
That part of Florida is a thin line of connected suburban sprawl following the line of the Atlantic coast. There are some high rise condos/hotels on close to the beaches at various parts, but Titusville (the area across from Cape Canaveral on the mainland) is mostly 1-2 story buildings. It's kind of a shithole imo, but I'm sure there are people who like it.

>>15158535
Shelby leaving will probably put a damper on new agencies moving into Huntsville, but there's more than enough stuff already there for it to continue to grow as an aerospace hub. Marshall, MDA, Redstone, and the contractors that sell to them will continue to grow the local economy, while the arrival of space command (assuming that goes through) will bring even more money in.

Additionally, Shelby's successor is his chief of staff. While she won't hold the committee positions that allowed him to hold so much sway, she does have the contacts and experience necessary to move into that role over time.

>>15158590
Funny that pic related is now Alabama's senior senator. Not sure about Shelby's replacement having much power. While she may know the right people, there's a big difference between dealing with someone who you've exchanged favors for decades and someone who was their assistant (even if Chief of Staff). I'm sure she'll want to move in his footsteps but everyone else is going to smell blood in the water and come after assets they wouldn't have dared go after while Shelby was in power. The location of Space Command will be a big sign of if there's going to be a large momentum shift or not.

>>15158623
I think you're right about the dynamics at play in terms of congress. It'll be interesting to see what happens.

Huntsville's blob of space/defense contractors and agencies (combined with its low cost of living) will continue to drive growth organically in the short term, but losing that congressional influence could be a major problem over the next few decades.

The only reason why spaceplanes are based desu. Also the only reason why a flyback booster should be built.

>>15159079
Falcon Heavy uses flyback boosters

>>15159079
I think it really depends on how reliable they can get propulsive landing.

If it has like a 1% crash rate and people are trying to use the same booster hundreds of times, that shit's going to add up.

>>15159079
Flyback boosters have a horribly mass penalty though. Something like 1/4th the booster mass is the rocket itself, compared to about 1/10 for a VTVL rocket stage.

>>15159100
Falcon has zero redundancy in landing. Starship can at least lose 1/3 engines and be fine.

>>15159108
Doesn't have to be efficient or practical. I just want to see it done so humanity can say "yeah we did it."

Why doesn’t the US government subsidize smallsat launchers based on solid fueled missiles like China does
>Inb4 Minotaur, Taurus, Pegasus
All of those are $50+ million per launch and fly once a year max. You think they’d be cheaper

>>15159150
He's an investors for OpenAI. An early round seed funder too

>>15159153
Is Tom actually gay or was it a misclick?

>>15159159
Minotaur C, my beloved

>>15159134
It's not a huge stretch to see them doing it. They dropped their mega-constellation ideas from the big five-year plan they just published, but they are building and launching an absurd number of satellites even without that. They're going to try to launch at least seventy Long Marches, and most of those will be LM-2/3/4s which will be lifting satellites in trios if their 2022 performance is any guide. A few of their newspace sino-minotaurs are going to try for a regular flight cadence and most of their payloads are going to be things like cubesat clusters, so the number of overall spacecraft is going to add up fast.

>>15158638
I actually enjoyed it immensely and am looking forward to the next instalment.

I never read the books though so maybe that's why I'm not disappointed.

>>15159159
Because the US has multiple commercial smallsat launchers who developed their own liquid engines.

>>15159159
They're expensive because they hardly ever fly. The more you launch a rocket the more flights you have to spread its yearly GSE and production line upkeep across. A lot of the Minotaurs are built using decommissioned ICBM stages and are legally restricted to government payloads, which don't show up very often. Pegasus had the problem of using propulsion and major subsystems that was designed by and purchased from subcontractors, which didn't help the price.

There's also the problem that direct government subsidization of launch vehicles was something we raked Russia, Ukraine, and China over the coals for when they were trying to get into the western commercial market. Anything that overtly hypocritical would be just begging for political or economic retaliation from our foreign competitors. There aren't any real winners walking down that road.

China's main goal with their new small launch companies isn't to get cheaper launch vehicles. It's a side benefit, but the main thing they're after is growing their pool of internal spaceflight talent. Handing off a IRBM to some bright-eyed young engineers and asking them to build a launch vehicle is a pretty slick way of mass producing talent.

>>15159134
A cubesat is a "spacecraft," this metric is meaningless

>>15159182

That song became popular for being used in a film about a tragic ship doomed to sink.

>>15159226
It’s interesting how “weird” early space startups were. Nowadays, everyone builds kerosene or methane smallsat launchers and scales them up. Back then, you had hybrid motors, clusters of five or six identical boosters, random collections of solid motors. Truly an odd time.

What’s interesting too is that most of them had jack shit in terms of money. SpaceX lucked out by having Elon; even Kistler imploded due to a lack of money

The problem wasn't having the foam, it was the foam being CFC-free because think of the baby ozone layers, NO EXCEPTIONS!
The foam was needed because hydrolox is such a total bitch to keep cold. I wonder if it would even have liquefied oxygen out of the air, that would be so fun to have oxygen dew all over the fucking place.

> The RDRE differs from a traditional rocket engine by generating thrust using a supersonic combustion phenomenon known as a detonation. This design produces more power while using less fuel than today’s propulsion systems and has the potential to power both human landers and interplanetary vehicles to deep space destinations, such as the Moon and Mars.

>Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, and primary collaborator IN Space LLC, located in West Lafayette, Indiana, are confirming data from RDRE hot fire tests conducted in 2022 at Marshall’s East Test Area. The engine was fired over a dozen times, totaling nearly 10 minutes in duration.

> The RDRE achieved its primary test objective by demonstrating that its hardware – made from novel additive manufacturing, or 3D printing, designs and processes – could operate for long durations while withstanding the extreme heat and pressure environments generated by detonations. While operating at full throttle, the RDRE produced over 4,000 pounds of thrust for nearly a minute at an average chamber pressure of 622 pounds per square inch, the highest pressure rating for this design on record.

> Additional milestones achieved during the test include the successful performance of both deep throttling and internal ignition. This successful demonstration brings the technology closer to being used with future flight vehicles, enabling NASA and commercial space to move more payload and mass to deep space destinations, an essential component to making space exploration more sustainable. Because of NASA’s recent success with the RDRE, follow-on work is being conducted by NASA engineers to develop a fully reusable 10,000-pound class RDRE to identify performance benefits over traditional liquid rocket engines.

did you loose control because of lost signal or when staging? if its lost signal then thats because the ground stations dont cover the entire earth and when flying over the pacific you often loose signal. if its when staging you likely dont have the right amount of avionics and need to fix it in the editor

How is that any different, your dome will get dusty. I guess you could eject the dome eventually but still. The chynease had both passive and active dust resistant measures on their rover and it worked well for a while but now it seems even their precautions couldn’t save it in the end

>>15159950

so why aren't there more electric ships if its supposedly easier than electrifying cars?
i mean you could be right and there is some other things affecting the commercialization than physics and I tried to find out the general equations affecting the energy expenditure of cars vs ships, but maybe it isn't just cars (linear) and ships (sublinear) with respect to mass

even with electric cars the scaling is superlinear, as the batteries themselves weight something and thus doubling the the amount of batteries won't just double the range as you also double the mass from the batteries
