Abstract
Space travel from our planet made its bow to the modern world on Friday, October 4, 1957, when Soviet scientists launched an earth satellite. The sphere weighed 184 pounds, was equipped with a radio transmitter, had a speed of 18,000 miles per hour, and began circling the globe at a height of about 400 miles each 96 minutes, or 15 times a day. Within a short time after the launching, it was spotted and reported from various observation posts here and abroad.This article can also be found at the Monthly Review website, where most recent articles are published in full.Click here to purchase a PDF version of this article at the Monthly Review website.
