Showing results for "Space Science" in 20th Century

When Ed White, clad in his gleaming space suit with a large American flag on his left shoulder, eased himself outside his Gemini spacecraft in 1965, Americans had a new space hero. They also learned a new acronym: EVA, short for extravehicular activity, more commonly known as "spacewalking." Though few understood the tremendous risks White was taking in his twenty-two-minute space walk, Americans watched with immense pride and patriotism as White, tethered to Gemini 4, propelled himself around the spacecraft with a pressurized oxygen-fueled zip gun.

In Apollo's Legacy, space historian Roger D. Launius explores the many-faceted stories told about the meaning of the Apollo program and how it forever altered American society. The Apollo missions marked the first time human beings left Earth's orbit and visited another world, and thus they loom large in our collective memory. Many have detailed the exciting events of the Apollo program, but Launius offers unique insight into its legacy as seen through multiple perspectives.

A fascinating piece of historical scientific writing, written in 1913 by E. Walter Maunder (F.R.A.S.), the superintendent of the Solar Dept. at the Royal Observatory in Greenwich. The book is a snapshot in time showing the evolution of thinking on the solar system and cosmology. The author considers, in fine detail, the plausibility of life on other planets within our solar system, the requirements for such life, and the barriers that life faces.

On October 4, 1957, a time of Cold War paranoia, the Soviet Union secretly launched the Earth's first artificial moon. No bigger than a basketball, the tiny satellite was powered by a car battery. Yet, for all its simplicity, Sputnik stunned the world.
