Three atmospheric crises. One programme. Polar orbiting spacecraft capture CFCs before they reach the stratosphere and inject ozone directly into the Antarctic polar vortex. Water delivery ships replace what glaciers no longer provide for two billion people. The Sahara becomes a continent of farms. The asteroid belt has the water. The factory builds the fleet. The infrastructure already exists.
Chlorofluorocarbons — CFCs — destroy stratospheric ozone by a catalytic chain reaction. One chlorine atom from a single CFC molecule can destroy up to 100,000 ozone molecules before it is deactivated. The Montreal Protocol stopped new CFC production in 1987. The legacy inventory — 15 to 20 billion kilograms distributed through the atmosphere — continues to leak from ageing refrigeration equipment, foam insulation, and old air conditioning systems. CFCs have atmospheric lifetimes of 50 to 100 years. The ozone layer will not fully recover until mid-century at the earliest. Unless we remove the CFCs.
Every CFC molecule is carbon + chlorine + fluorine. All three are useful at L4. The factory needs exactly these chemicals — and currently has to ship them from Earth. The ORP eliminates several Earth-origin manifest dependencies.
Mountain glaciers are the freshwater timing mechanism for two billion people. They store winter precipitation and release it through spring and summer — the buffer that keeps rivers flowing when seasonal rainfall stops. When glaciers disappear the rivers become binary: flood in winter, dry in summer. Agriculture, drinking water, and hydroelectric power fail simultaneously in the dry season. The glaciers are not coming back on any timescale relevant to the people who depend on them. The water must come from somewhere else.
160 to 250 billion tonnes of fresh water per year that glaciers used to deliver but no longer do, above what increased rainfall compensates. This is the minimum annual replacement volume to prevent agricultural collapse and drinking water failure for up to 2 billion people within the next 30 to 50 years.
6,000 to 10,000 years ago the Sahara was green. Lakes, rivers, hippos, crocodiles, and human settlements across what is now hyperarid desert. Monsoon rains penetrated further north. The vegetation itself maintained the moisture cycle — leaves reflect radiation, roots hold water, transpiration humidifies the air, rough canopy draws in Atlantic moisture. The Sahara transitioned from green to desert in a few thousand years when orbital forcing reversed. The physics of a Green Sahara is not hypothetical. It happened. It has two stable states — desert and green — and a tipping point between them. Push enough water into enough of the Sahara to establish 15% vegetation cover across a connected region and the system flips. Natural rainfall does the rest.
The Parched Planet programme as currently specified — 30 ships, polar orbit — delivers 0.12 km³/year. It is a demonstration mission. The gap between demonstration and full programme scale is bridged by one thing: the L4 factory manufacturing rate. The water exists. The asteroid belt contains enough to fill Earth's oceans several times over. The constraint is how fast the factory can build ships.
| Programme level | Volume (km³/yr) | Fleet size | Ship mass required |
|---|---|---|---|
Demonstration Current Parched Planet spec |
0.12 | 30 ships | Seed ship manifest |
Glacier Emergency Replace annual deficit |
160–250 | ~50,000 ships | ~500M tonnes — less than half of asteroid 2020 XL5 |
Emergency + Sahara Trigger Minimum programme |
560–650 | ~150,000 ships | ~1.5 billion tonnes. Multiple belt bodies. Factory Year 3–5. |
Full Programme Emergency + complete Sahara |
~2,100 | ~525,000 ships | ~5.25 billion tonnes. 20-year factory programme. Self-funded from Speculāris revenues. |
Water supply is not the constraint. C-type asteroid 2020 XL5 alone contains 112–224 million tonnes of water. The asteroid belt as a whole contains more water than all Earth's oceans combined. At full programme scale — 2,100 km³/year — 50 years of operations consumes 0.01% of accessible C-type water inventory. The factory builds the ships from the metal fraction of the same asteroids that supply the water. The programme is self-contained.
Three crises. One programme. The same factory. The same asteroid water. The same delivery infrastructure. The ozone hole that formed over Antarctica while the world was building refrigerators. The glaciers that fed the Indus for ten thousand years, melting in one century. The Sahara that was green when the first cities were being built, waiting for the water to return.
The asteroid belt has been holding this water for 4.6 billion years. The factory is being built now. The first ships launch at Month 4.4 of L4 arrival. The demonstration is proof of concept. The full programme is the natural consequence of scaling what the factory already does.
The glacier that feeds the Indus has been melting for a century. The people downstream have been waiting for someone to notice. We noticed.
Speculāris — On the cutting edge.
Ozone repair. Glacier replacement. Sahara greening. All enabled by the same factory, the same water, the same delivery fleet.
