Termination Shock
Climate scientists are warning against geoengineering, describing it as a game with potentially catastrophic results. Separately, NASA researchers are using solar wind forecasts to predict when the New Horizons spacecraft will reach the heliospheric termination shock. This boundary marks where the Sun's influence fades into interstellar space.

Termination Shock: Climate Risks and Space Boundaries
confidence 90%Climate scientists are warning against geoengineering, describing it as a game with potentially catastrophic results. Separately, NASA researchers are using solar wind forecasts to predict when the New Horizons spacecraft will reach the heliospheric termination shock. This boundary marks where the Sun's influence fades into interstellar space.
What's confirmed:
- Four climate scientists, including Michael Mann and Julia Slingo, warn that geoengineering could have catastrophic consequences.
- The New Horizons spacecraft is moving toward the heliospheric termination shock.
- Voyager 1 is the most distant human-made object from Earth.
- Voyager 1 is projected to be one light day from Earth in November 2026.
Still unconfirmed:
- New Horizons may cross the heliosphere boundary between 2029 and 2040.
- A startup raised US75 million to try reflecting the Sun to buy time for net zero.
