Are there any ISP Numbers
ISP = Specific impulse, not internet service provider.
It's a measure or rocket fuel economy.
For example the Dawn probe, which rendezvoused with Ceres and Vesta asteroids, had thrusters with a specific impulse of 3,100 s and produce a thrust of 90 mN.
Without ISP numbers, it's just a press release.
