I read the book about 1965. Involves identical twin girls. One was sent into space. The twin on earth responded/had the same feelings as the sister in space.

    This is super vague, can you please add some more details? And even check out How to ask a good story-ID question? to see if it helps jog your memory.

    Plot-wise, Ship-Sister, Star-Sister by Robert Silverberg seems to be a good match, but (a) it was published in 1973, and (b) it's a novelette, not a novel (it was expanded into the novel Starborne, but only in 1996.)

Some of the later 'Chris Godfrey of Unexa' series by Hugh Walters has a pair of telepathic girl twins who provide communication between the ship and Earth.

  • I was thinking of that myself. The first Walters book I ever read was Mission to Mercury in which the young male heroes first meet the girl who will be part of their crew on the trip to Mercury. I think the excuse was that when you got so close to the sun, its radiation would scramble any attempt to maintain communications with Earth via regular radio. So having a telepathic communications officer could be very useful.

  • Did this include the "had the same feelings" element mentioned in the question and lacking in Time for the Stars? You get my upvote anyway. This seems like a better fit. Commented Jan 24, 2018 at 18:20
  • Yes. At one point the people on the ship are preparing to enter hibernation pods, and they forget their pre-sleep injections. The girl feels her sister on Earth having hers; which reminds them.

  • Yes! I remember reading several in this series when I was in elementary school (5th and 6th grades). Made me love science fiction. My neighbor's daughter worked for NASA as a mathematician and programmer, and I would banter about space travel with her at Christmas visits.

Despite the lack of detail I will guess this is Time for the Stars, by Robert Heinlein. It was published in 1956.

Pat and Tom are identical twins who are found to be able to communicate telepathically. Tom is sent to space on a colony ship while Pat remains behind, providing a means of communicating between ship and Earth.

Unlike the question, Pat and Tom are boys. There are other identical twins split the same way, who are girls.

  • There are, however, twin girl pair communicators on the same ship as Tom, and on other ships.
