A cleaner future with Stoke
Stoke’s high-efficiency engines significantly reduce harmful emissions, creating the lowest environmental impact of any existing or proposed rocket.

Earth deserves better.
Most rockets today rely on solid rocket boosters or kerosene-based engines, both of which release harmful emissions into the upper atmosphere. According to a recent study by the American Geophysical Union:
- Kerosene engines account for 70% of all rocket-driven global warming impacts, emitting black carbon soot that traps heat 500x more effectively than aviation emissions.
- Solid rockets account for 28% of rocket-based warming and release ozone-depleting chemicals like chlorine and aluminum oxide.
There’s a better way.

Nova is different.
Our liquid natural gas/liquid oxygen first stage and liquid hydrogen/liquid oxygen second stage combine to form the world’s most efficient fully reusable rocket.
These clean fuels eliminate black carbon emissions — the single most damaging factor in today’s orbital launches — and reduce rocket-driven global warming by 98%.

Stoke is working to build a sustainable, scalable space economy by unlocking space mobility.
