The Personal Spacecraft Problem
In 2025, a seat on a Blue Origin suborbital flight costs approximately $200,000–$450,000 for 11 minutes above the Kármán line. SpaceX's Crew Dragon missions run $55 million per seat. The Polaris Dawn mission — the first commercial spacewalk — cost over $100 million per crew member.
These are extraordinary achievements. They are also proof that space travel remains an industrial-scale operation requiring teams of hundreds, months of training, and budgets measured in hundreds of millions.
The automobile was once equally exclusive. In 1900, fewer than 8,000 cars existed in the United States. By 1920, Henry Ford had shipped 15 million Model Ts at $260 each. The technology didn't change — the approach did.
CasDrive asks the Ford question for spacecraft: What would it take to make a personal vehicle that flies to Mars and parks in your driveway?
Three converging trends make this question less absurd than it sounds:
Propulsion physics is opening up. The Casimir effect — a measurable quantum force — suggests that vacuum energy is real and extractable. We are not at "engine" stage. But we are past "impossible" stage.
Materials science is catching up. Carbon nanotube fibers now achieve tensile strengths of 80+ GPa. Radiation-shielding composites have demonstrated 30% mass reduction over traditional aluminum. The trajectory is pointed in the right direction.
AI-accelerated design is compressing timelines. What took years of wind tunnel testing can now be simulated in days. CasDrive intends to leverage AI as a genuine design accelerator.
If you had told someone in 1900 that in 70 years, humans would walk on the Moon, they would have laughed. If you had told them that in 120 years, a private company would land rocket boosters on drone ships, they would have called you insane.
So: when will a personal spacecraft sit on a home landing pad? We don't know yet. But we intend to find out.
