New satellite propulsion system

[scaesare]

Portal Space is developing a new Solar Thermal Propulsion system for satellites, theoretically giving them much greater delta-V cpability.

Run by the guy who headed up Raptor design for SpaceX.

Like nuclear thermal, but with the nuclear bit staying in the sun.

That big fusion reactor up there is handy...

Fission.. fusion all the same when it comes to risk. You guys are not taking its dangers seriously. One day it is going to explode. Guaranteed. It is a mathematical and scientific certainty

delta v for dummies, I could understand it, thanks for posting

Well... different risks, right? The immediate fission vs. fusion byproducts for one... the long term potential risk of supernova for another...

But perhaps you are right, and we should consider decommissioning our local fusion reactor...

Not until my tomatoes are ripe damnit!
