One human. One mission.
Advance humanity toward3.0 on the Kardashev scale
Sahil Chaudhary
I’m an aerospace engineer driven by a fascination with space, rockets, and the future of humanity.
I’m studying across engineering, physics, AI, energy, and other frontier fields with one long-term goal: help make Earth better, push humanity beyond the stars, and eventually turn today’s science fiction into real technology.

Interplanetary space. Where it began.
It started on the last bench.
Where it began
7th gradeIt started in the seventh grade, on the last bench of a classroom near the end of the school day. “If nobody has ever gone there, maybe one day we will.”

My best friend and I were talking about a video we had seen on black holes and wormholes — how black holes pull everything toward them, how strange wormholes are supposed to be, and how some theories suggest they could connect distant places, or perhaps something even stranger.
At some point, the conversation became simple:
We genuinely decided that someday we would try to go on a mission to a black hole.
I went home that day and started reading more.
One question became another. Black holes led to space. Space led to rockets. Rockets led to physics, engineering and eventually the much larger question of what humanity could become.
Rockets & ambition
9th gradeA few years later, around ninth grade, I discovered Elon Musk and became fascinated not only by rockets, but by the idea that an individual could decide to work on problems that looked impossibly large. That pushed me toward the idea of someday building a space company of my own.

From there, my curiosity kept expanding.
I started reading about people like Einstein, Stephen Hawking, Nikola Tesla and Michio Kaku. I became interested in biographies, philosophy, science fiction, and people like Steve Jobs who approached building in completely different ways.
Slowly, the dream stopped being only about rockets.
Aerospace engineering
That fascination eventually became concrete enough that I chose to study Aerospace Engineering.

I began thinking about interstellar spacecraft, advanced propulsion, Dyson spheres, artificial intelligence, energy, robotics and technologies that today still sound like science fiction.
Eventually I discovered the idea of civilization scales and Type III civilizations.
That gave a name to something I had already been imagining for years.
The long game
NowI know I may never see most of these things completed in my lifetime. I also know how extraordinarily difficult some of them are.

But I don’t think difficulty is a good enough reason not to move toward them.
So I’m trying to build my life in that direction — learning across fields, building things, starting companies, becoming a better engineer, and working on technologies that could move humanity even a little closer to that future.
I still want to see how far we can go.
The mission. A direction for a lifetime.
My mission is to spend my life helping push humanity toward a Type III civilization.
That ambition started with a fascination for space. As a kid, I became obsessed with black holes, wormholes, interstellar travel, and the idea that humanity could someday go far beyond Earth. What began as curiosity slowly became something much larger.
Over time, rockets led me to engineering. Engineering led me to physics, energy, AI, robotics, and the technologies that shape civilization itself. I started thinking beyond simply reaching space.
What would it take to build a civilization capable of surviving across planets, harnessing energy at extraordinary scales, constructing technologies like Dyson spheres, developing radically new propulsion systems, and eventually travelling between stars?
Most of those goals are far beyond what one person — or perhaps even one generation — can achieve. But that doesn’t make them meaningless.
I want to build technologies that move humanity in that direction: first by improving life and technological capability on Earth, then by helping expand civilization beyond it.
Earth is where the work begins.
The stars are where I want it to lead.
I don’t think the path starts with a spaceship.
Before SpaceX and Tesla, Elon Musk built Zip2 and X.com. That made something click for me: before trying to build the most capital-intensive technologies in the world, I may first need to build companies that solve real problems, create real value, and give me the resources, experience and network to attempt something much larger.
An earthly foundation
Build ventures
First, I want to build companies in areas such as AI, robotics, blockchain and other emerging technologies — not as distractions from the long-term mission, but as stepping stones toward it.
The goal is to spend a few years building useful companies, learning how to build teams, products, infrastructure and organizations, and eventually use that foundation to start the space company I ultimately want to build.
Access to space
Reusable rockets
Fully reusable rockets, launch systems, advanced propulsion and the technologies required to move humanity farther into space.
Somewhere to stay
Moon / Mars
The technologies required to turn temporary missions into permanent civilization: habitats, energy systems, resource utilization, manufacturing, robotics, transportation and life-support infrastructure.
Farther than orbit
Spaceships
Beyond rockets and planetary bases, I eventually want to work toward spacecraft designed for long-duration travel — vehicles built not just to reach orbit, but to carry humanity deeper into the Solar System and one day toward the stars.
The science underneath it all
Sci-fi engineering
Studying and building technologies inspired by biology and the nanoscale world — from nanorobotics and biomimetic machines to future systems that could improve health, manufacturing, exploration and survival in extreme environments.
New materials and manufacturing approaches — including areas such as graphene and nanomaterials — that could enable lighter, stronger, more efficient and more capable machines.
Intelligent systems that can reason, design, operate machines, automate scientific work and eventually help humans build and maintain complex systems both on Earth and beyond it.
A longer horizon
Type I / Type II / Type III
Help move Earth toward a more advanced and energy-abundant civilization.
Then keep pushing toward the kind of civilization that can operate across planets, stars and eventually far beyond them.
I don’t see these as separate interests. To me, they are pieces of the same long-term puzzle.
The exact path will change. The direction won’t.

From my internship report: CSIR NAL, Bangalore
Three months in the Computational & Theoretical Fluid Dynamics (CTFD) Division at CSIR National Aerospace Laboratories (18 Aug to 18 Nov 2025), working through meshing, SU2 simulation, ParaView post-processing and validation against experimental data.
NACA 0012 airfoil. Structured C-mesh and O-mesh with a boundary-layer extrusion in Pointwise and GMSH, inviscid Euler simulations in SU2 at several angles of attack, and Cp distributions and contours in ParaView.
RAE2822 supercritical airfoil. RANS with the Spalart–Allmaras model at about Mach 0.729 and 2.31° angle of attack. The shock location matched the experiment closely, with minor differences in pressure recovery near the trailing edge.
ONERA M6 wing. A 3D unstructured mesh refined around mid-span, run at about Mach 0.8395 and 3.06° angle of attack. Cp was compared with wind-tunnel data at y/b = 0.20, 0.44, 0.65, 0.80, 0.90 and 0.95, and the higher tip suction peak and the shock strengthening along the span were captured, with reasonable agreement.
Eglin wing-store separation. Mesh built in Pointwise, store translation and rotation scripted with rotation matrices from experimental positions (6-DOF), simulated in SU2, with forces, moments, trajectories and flow features post-processed in ParaView, plus mesh-independence and convergence checks.
Store Separation Simulation

Explore

Created and refined the mesh in Pointwise, configured flow and motion conditions in SU2, advanced the store through multiple time steps using scripting, and studied 6-DOF behavior including pitch, roll, yaw, translation, orientation, aerodynamic forces and moments.
The work involved rotation matrices, Newtonian mechanics, rigid-body equations, and post-processing of the separation trajectory.
