Far Rainbow (Russian: Далёкая Радуга, romanized: Dalyokaya Raduga, pronounced [dɐˈlʲɵkajə ˈradʊɡə]) is a 1963 science fiction novel by Soviet writers Boris and Arkady Strugatsky, set in the Noon Universe.

Leonid Gorbovsky, whose Tariel II has delivered scientific equipment to Rainbow, pays a visit to Matvei Vyazanitsyn, the general director of the planet, then returns to his ship, when the ominous news come.

Robert Sklyarov witnesses the Wave destroying semi-automatic charybdis Wave-stopper tanks and tries to pilot one manually to give his friends time to flee.

At this time, Gorbovsky personally takes the hard decision on who is to be saved (same as Robert not long ago) and announces that only the children will be transported onto the orbit on Tariel II.

Tariel, dismantled from the regular spaceship to the status of life raft and leaving behind parts of her machinery as well as her captain, lifts off when the Waves (both northern and southern) are a few kilometers away from the Capital.

Shortly before the two reach it, Gorbovsky, Camill, Sklyarov and Turchina (in peace with Robert again in their last minutes) sit on the beach not far from the city and watch a team of null-T-testers float their blind team-mate toward the southern Wave, while he is playing a song on the banjo.
