The cover for the first book in a long British YA series begun in 1957.
It's intriguing to me as being touted as "realistic space travel"--as realistic as a book for young readers in 1957 can be, anyway. It also uses weight as an excuse for a teenaged protagonist: the British rocket on-hand can't haul a full-sized man to the Moon and young Chris is only five feet tall.
...Which is doubly interesting because god forbid they use a woman pilot rather than rely on a rookie teen. Very 1957, IOW.
This turned up in a 1995 novel and anime television series called Rocket Girls.
The fictitious Solomon Space Association is developing the low-mass suits since their anemic one-lung LS-5 rocket can barely lift itself off the launch pad, let alone any payload. They are reduce to using 16 year old girls as astronauts (predictable for a Japanese anime). They only weigh 38 kilograms, instead of 60 kilograms of adult male astronauts. They take up less room in the control cabin as well.

Dwarfs are smaller than humans, but have a higher mass which negates their value to space flight.
