Terran-R, Neutron, Nova, Eclipse. Gonna be sweet. Also, Terran-R is really big. About 85-90% the thrust of New Glenn.

@LACYF50 I'm a very happy Cursor customer. I think it's more obvious than Twitter was.

3%. It's being valued at 3% of everything else. For a platform with millions of developers. That has the potential to make or break SpaceX's AI push. Yeah, it's probably worth it as an equity swap.

Roughly 6X entire investment in Starship program. Is whatever this thing is worth 6x the money you have ever put into the foundation of your company's entire future. Its 6x more valuable than, everything...? As with all things AI, this cannot be made sense of.

@brickmack It's much less common than other industries but it does exist. Most of the cases I've seen came from people who already got into the industry then companies were willing to take them even remote only.
It's going to be tough to break in as remote.
English
@Morgan628 Are there any space software jobs at all with remote work as an option? I want to work in the space industry but there's just none anywhere near me, and moving across the country isn't financially realistic anytime soon. Best I got was artist jobs, fun but that's all short term
English
All true, but also don't be afraid to give the STEM side a shot if that's what you really want.
I started college over at 30 because I didn't have a stem degree. It was rough but I knew what I wanted. It is possible and there are people who will give you a chance.
cait@RockettLord
If you want to work in the space industry but don’t have a STEM degree here are all sorts of other options available: Journalists and communicators! Videographers and photographers! Executive Assistants! Accountants! Finance and business! Learning specialists! Human resources! Every space company needs a plethora of humans in all types of role to be successful in meeting their goals! If you need help with finding other space companies that complement NASA and their goals (most hardware is built by companies that have contracts with NASA!) check out the post I will link in the comments 👇👇

@IanDodds_ @connorkapoor Opportunity is always circumstantial. Really good and driven people will keep pushing until they get through somewhere but it still requires someone to give you a chance.
Luck and timing always matter. I got crazy lucky with how I got my specific job.
English
@Morgan628 @connorkapoor In my experience the good ones will break through, they dont need any exceptions. they are not fazed by hr filters! not sure how many good ones fall through the cracks though
English
I’ve been interviewing a lot of folks over the last few weeks for entry level engineering roles;
If there was one piece of advice I could give to everyone in a engineering related field
You NEED to have examples of things you’ve built, with your hands. Senior projects are usually kind of bullshit and do not make a portfolio.
English
@IanDodds_ @connorkapoor That one is harder. I referred one of my company's best engineers who never went to college because I met him doing amateur rocketry stuff. As much as I am willing to hire diverse backgrounds it's hard to get through HR filters to land on someone like me's desk.
English
@Morgan628 @connorkapoor Do you think there is a limiting factor to get the interview in the first place? Like a key word filter?
English
@IanDodds_ @connorkapoor Honestly that's easy. If you really did the work at the depth needed to learn the fundamental skills and knowledge it'll come out in talking about the project.
English
@connorkapoor Inversely, how do you guage someone who has built a lot of projects, can speak about them in detail, but does not have an engineering degree or prior engineering role?
English
That's my boss.
Funny story, I was so early at Impulse I interviewed him.
Tons of open roles on both my team and the rest of spacecraft software.
Impulse Space@GoToImpulse
“We’re building software that directly shapes the mission’s success.” We sat down with Atta Kashmiri, Spacecraft Software Manager at Impulse, to break down what it’s like to develop the tools, infrastructure, and flight-critical systems that keep the Mira and Helios programs moving forward – and how it feels to get your hands on real flight hardware.

@Graham_117 @A_J_Higgins It's fantastic for the outer solar system.
Maybe we break through with some other tech that is better, but NEP could be pieced together with existing technology (no engineering miracles).
If we wanted to we could go build it today.
English
Yes, can't see NEP ever being competitive in the inner solar system. Outer system may be different, eventually.
It often seems like proponents of NTP/NEP haven't really updated to account for the huge improvements in chemical rockets + solar PV in the last 20 years.
Andrew Higgins@A_J_Higgins
Quick reality check: — Nuclear electric propulsion (NEP) won’t shorten Mars transit times. — We don’t have a space‑rated 25 kWe reactor — and even a crash program to develop one would take a decade. — Inside Mars’ orbit, solar electric propulsion already outperforms NEP.
English
@DJSnM @XPichner @peterrhague I was thinking even shorter term than that.
Casey did a post a while back looking at how some mass trades look at the lunar south pole locations just for keeping a base running through the long occasional nights. Even for that it could be worthwhile.
English
@XPichner @Morgan628 @peterrhague Exactly. Lots of regolith processing strategies require lots of heat, photoelectric is a very inefficient way to do this in terms of area per watt.
English
This is one of those ideas that seems neat but is terrible in a world where batteries have scaled.
Photovoltaics+batteries have won in a landslide.
Volcaholic 🌋@volcaholic1
China’s solar power plant in Dunhuang uses around 12,000 mirrors to focus sunlight onto a central tower, heating molten salt to extreme temperatures. That heat is stored and used to generate electricity on demand, including after sunset.
English
@XPichner @DJSnM @peterrhague No birds, no clouds.
I'm unconvinced it's better than photovoltaics (haven't looked at detailed proposals) but it seems plausible.
Even in the near perpetual sunlight locations there are rough long stretches of darkness that make battery mass to bridge the gap huge.
English
English
@docentdemagogue The other thing is that this requires the sunlight to be directional to be effective. It completely goes to shit in overcast conditions.
Photovoltaics take a big hit but still generate meaningful power.
English
@Morgan628 Turns out maintenance on a structure full of pipes that cycles between ambient and sun temp every 24 hours is not cheap
English
I have tickets for a big group 70mm Imax screening in a week.
I don't know if I have the willpower to resist seeing it on my own first. I know I'm going to see it repeatedly in theaters regardless.

You have no idea how much it means for me to have the opportunity to save the Earth with the guy who lambasted James Cameron for using Papyrus.

Go watch #projecthailymary and see Ryan Gosling and Mallory McMorrow save the EARTH

@chr1sa @faraz_r_khan The majority of SpaceX engines are not printed. There are some specific parts on Raptor that are.
There are other engines that are mostly printed, but the material properties are inferior compared to using more traditional methods.
English
@faraz_r_khan And yet almost all modern rocket engines, including the SpaceX ones, are now metal 3D printed
English
For years, 3D printing has been relegated to a prototyping technology, not a production one, on the grounds that it was too slow and expensive to compete with injection molding at scale.
That's now changing with massive-scale print farms in China (see link in comments). As a result, the economic crossover point for using 3D printing rather than injection molding is shifting rapidly to the right.
