re: Something to consider before sending nano-probes speeding off into space

If they pass close enough to a star or even a large planet, the gravitational pull might be strong enough to slow it down

Simply turning off the laser propulsion prior to entering the solar system's heliosheath would be enough.

Dunno how much it will slow after having to push against solar wind the last few years, but it will probably be pretty big compared to the top speed.

Might only be a couple percent light speed.
