An Interview: with a Space Scientist

with contributions from Homer E. Newell, Jr.

The great Russian space scientist, Tsiolkovsky, said, "The Earth is the cradle of humanity, but mankind will not stay in the cradle forever."^{Quoted in Soviet Space Exploration: The First Decade by William Shelton, pp. 12, 13;}

The universe is the domain of man. For centuries men have thought they were trapped on the earth and couldn't get away. Going to the moon, Mars, or Venus is a matter of expanding our human concept of what our place is in the universe.

That reminds me of what Mrs. Eddy writes, "Pilgrim on earth, thy home is heaven; stranger, thou are the guest of God."^{Science and Health, p. 254;}
