You have to be very careful to choose your optimization metrics well. "Reusability" as a technology is fantastic because it let's us put more payload in orbit. Optimizing for "minimum engines thrown away" or "common design" is bad if it hurts the ability to operate.

Starship is on Raptor 3 and still no where close to mission ready. Since 1981, a total of 46 RS-25s were used for the 135 Shuttle launches and what is coming up on the 2nd Artemis flight. Starship threw away more than that in only 2 flights.

@EverestBrady @bennbuilds More and more each day. Spindle Uptime and % of parts made in house are both great KPIs. Ultimately the goal is to move a lot to high volume forming processes though.

I also recommend investing in a machine shop, at any scale!
Zane Hengsperger@zanehengsperger
what’s stopping you from taking out a loan and firing up this bad boy in your garage?

We're building some really cool stuff here @reflectorbital and you should come build with us!
Ben Nowack ☀️🌎🪞@bennbuilds
Built a space mirror, launching soon

@RockettLord I've been trying to get an internship @bps_space for years man...

Wanna work/intern for a space company but you’ve exhausted all of the job apps for NASA & SpaceX?? I gotchu! Below is a thread of some of the coolest space companies in the business. From rockets to satellites to payloads, its all here👇✨ 🚀

What a fantastic AstroAwards! Great to see friends, talk rockets, show off @reflectorbital, secure the thinnest of victories in space trivia, and enjoy my favorite DJ set! Huge thanks to @FireflySpace for hosting us for one heck of a static fire!

@AI_in_LEO @TiagoNugent @reflectorbital Hi! happy to discuss what we can - specularity is critical for our mirrors for exactly the reason you mentioned. Achieving that specularity requires novel mirror systems that aren't present on our conference demo units, and don't work in an atmosphere/under gravity.
English
@TiagoNugent @reflectorbital I've inquired in quite a few places and have never gotten an answer on that one. I think they're aware of it. But it exists as a technical issue keeping their goals from reality which they cannot publicly discuss because investors would pull out.
English
we used the @reflectorbital mirrors to give the blue ghost panels anboost
Firefly Aerospace@FireflySpace
We’re honored to receive an Astro Award! Congrats to the Firefly team whose relentless dedication made Blue Ghost Mission 1 a success! This is just the beginning. With more missions booked, we're building on this achievement to continue supporting the growing lunar economy.

I really hate it the take "you learn more from mistakes." If there's one way to do it right and a million ways to do it wrong, doing it "wrong" is incredibly low signal.
It can force you to grow your understanding of a problem, but nothing is stopping you from just doing that.
Philip Johnston@PhilipJohnston
Unfashionable truth: You learn a lot more from success than from failure! 🤓

Real Engineering features Reflect!
I remember when Real Engineering told Zipline’s story. Incredibly cool for Reflect to now be in the spotlight!

Real Engineering @RealEngYT explores the future of space-based solar and features our Chief Engineer, Charlie Garcia @Astro_Chuck. From megastructures of the past to lightweight reflector satellites, the future of clean power is getting closer.

I got to talk with my friend @TheBrianMcManus from Real Engineering about the incredibly cool mirror technology we're working on here at Reflect.
English
This is *the* coolest thing to see, and I've made a lot of mach diamonds.
Tristan Semmelhack@4TristanS
You still have no idea how big this reflector is. This is a real image
English
Way to go @blueorigin and the thousands of people who worked hard to make this one happen! What a beautiful landing!
English
I've been informed that this was the very first production @Prusa3D Core One L to ship. So excited to run it!

@Belstain @starsailing11 @andrewmccalip Super old post I know, but I feel compelled to point out that I made the above tweet with a full CNC shop in my garage 😅
English
@starsailing11 @andrewmccalip @Astro_Chuck True. Cnc is awesome, and people don't always know just how awesome it can be.
English
I did a little experiment this morning.
CNC processes can be ridiculously quick. Most people don’t have exposure to what an efficient process can do. Just because it takes a shop 4-10 days to get you the part, doesn’t mean there are days of labor in your part.
When I was writing the Amazon/Gigafactory thoughts, this is what I had in mind. How fast can a single programmer + 3ax CNC work cell go from CAD to part on the desk? What’s the lower physical limit to go through all the steps? No automation, no exotic equipment, no templating.
A comment from last weeks discussion gave me in idea.
Head to head on the same part, what is faster, CNC or 3d printing?
So I woke up this morning at 5am and gave myself 3 hours to do this experiment. CAD up a sample geometry with some representative features and time all the operations along the way. It has a few tight seal bores, threaded blind holes, features on both sides, wrench flats, and a few bolt patterns. Nothing special, just representative of what an average job shop part might be.

Love this team!
Reflect Orbital@reflectorbital
Happy Halloween from the Reflect Orbital team! 🎃
English
This team is killing it with the technical renders. Oh and @InversionSpace is pretty cool too.
Brian Mac Mághnais@TheBrianMcManus
We have been working on this reveal with Inversion for a few months now. Highest level animations we have ever made. Those parachute sims 🧑🍳 💋
English
Cool idea, probably should just build an orbital propellant depot. This makes the most sense if you're going somewhere one-way, fast.
Payload 🚀@payloadspace
The UK Space Agency announced a £150,000 contract to fund the study of a new kind of in-space OTV. The spacecraft is designed to use autophage propulsion—meaning, it uses and burns a fuel tank that is itself made of fuel—to change its orbital trajectory. payloadspace.com/uk-funds-desig…
