Science-fiction books were very influential for me as a teenager.
Although I read some early fantasy (like Bradbury's Martian
Chronicles), my real love was hard science fiction,
especially books by Arthur C. Clarke, Issac Asimov, Andre Norton (a
pseudonym for a woman writer) and Robert Heinlein. Their books
inspired me to go into aerospace engineering, leading at last to
being part of the team that built Sojourner Truth, the Mars rover
that was landed by the Pathfinder mission in 1997, and, finally, to
leadership of the U. S. Mars Exploration Program.
"Penguins are 10 times older than humans and have been here for a very, very long time," said Daniel Ksepka, Ph.D., a researcher at the National Evolutionary Synthesis Center (NESCent). Dr. Ksepka researches the evolution of penguins and how they came to inhabit the African continent.
Because penguins have been around for over 60 million years, their fossil record is extensive. Fossils that Dr. Ksepka and his colleagues have discovered provide clues about migration patterns and the diversity of penguin species.
