Reply to comment by Kal-El_Skywalker1998 in A New Mission Will Search for Habitable Planets at Alpha Centauri by Aeromarine_eng

The light sail carrying a wafer-thin sensor package is not meant to come back. One of the biggest challenges is figuring out how to slow it down as it approaches AC. What will most likely happen is the probe just zips through the system, grabs whatever data it can, and sends it back to Earth before flying on into nothingness. The alternative - slowing it down, redirecting it back toward Earth with orbital maneuvers, speeding it back up, and then having it actually reach us (not just zip through our system) - technically, we're not even close to that as a spacefaring species.

For all that to be true you need to have the power to lift all the heavy machinery required for mining and refining and building sub-surface habitats etc, and then accelerating it to the speed of the interstellar asteroid.

If you have all that sort of delta V available that buys a metric fuck tonne of radiation shielding.
