JUST IN: Charles Hoskinson on Midnight, says "we're building a DeFi kernel, a specialized DeFi language that is secure by construction to complement it, chain abstraction, Midnight Passport, and Midnight City—there's almost 10,000 people, and it's growing by leaps and bounds."
@elonmusk The Orbital Assembly Hub — a permanent “train station” in Earth orbit.
It’s where spacecraft are built, fueled, and launched to Mars & beyond.
Robots assemble; humans oversee.
A gateway for every interplanetary mission. 🌌 #OrbitalHub
@elonmusk Orbital Assembly Hub for Interplanetary Transport
A vision for a zero-gravity construction and logistics platform in Earth orbit — assembling, refueling & maintaining deep-space vessels too large or delicate to launch from Earth. 🌍🛰️ #Space#Engineering
@elonmusk 1️⃣ Surface-to-Orbit Shuttle — small, reusable, atmospheric.
2️⃣ Orbital Behemoth — huge, permanent, vacuum-optimized.
Each does what it’s best at — like planes & ships in global transport. #SpaceLogistics
@elonmusk One vehicle can’t master both.
Atmospheric craft need lift, heat shielding, high thrust.
Deep-space vessels need radiation shielding, modular design, efficient engines.
Mixing both means compromise — and inefficiency
@elonmusk To make space travel sustainable, ships can’t be single-use, all-in-one machines.
We must separate planetary ascent from interplanetary travel — just as we separate cars from ships and submarines.
@elonmusk The Problem: Building full spacecraft on Earth limits everything.
• Size/mass capped by rocket fairings
• Must survive gravity, heat & atmosphere
• Costs soar with each launch
• Crew face repetitive re-entry risk
@elonmusk The idea reshapes human spaceflight:
🌎 Atmospheric shuttles handle launch & landing.
🌌 Orbital vessels handle deep space.
Two specialized systems — reusable, modular, and sustainable. #SpaceArchitecture
@elonmusk Instead of launching full interplanetary ships, modular parts are ferried by reusable shuttles to an orbital hub — where robotic & human crews assemble them in microgravity.
This unlocks bigger, lighter, smarter spacecraft. ⚙️ #OrbitalAssembly
