Powered by a revolutionary laser-driven stardrive, the first interstellar expedition would reach the double planet circling Barnard's Star -- and find a world of wonders and dangers beyond all their imaginings.
Another great Forward read is Rocheworld.
Forward was a physicist, and created settings that only a physicist would be likely to think of.
They were going to the Barnard Star, but it had binary planets where one was all water.
Good book (if I recall)..
Rocheworld (AKA The Flight of the Dragonfly) - https://en.wikipedia.org/wiki/Rocheworld
and
Dragon's Egg - https://en.wikipedia.org/wiki/Dragon%27s_Egg
The really hard way though is to do what Robert Forward did in "Flight of the Dragonfly [1]: it includes 30+ pages and 12 figures with technical details. He worked it all out at the level of a real mission proposal.
A key part of the story takes place on a planet-wide forest with giant trees and a Gaia-like sentience (Midworld), its maguffin is a galaxy-threatening superweapon (The Tar-Aiym Krang), and a significant character is a wise old floating robot/AI that uses fields to manipulate things (Culture drones).
This reminds me of Interstellar, where I recognised the books that the authors had taken their influences from, such as Rocheworld by Robert L. Forward, which also features helpful robots that fold up with arms that have smaller-and-smaller subunits.
