The program had three stated goals: orbit a manned spacecraft around the Earth‚ investigate man’s ability to function

On April 9‚ 1959‚ NASA’s administrator‚ Dr. Keith Glennan formed its first astronaut class‚ the Mercury 7. Project Mercury’s objective was to place a human spacecraft into orbital flight around Earth. It was to observe how the human body reacted in space conditions. Many questions appeared as to whether they would come back safely or if were they the right people to do the challenge. The selection process in order to be qualified for NASA’s project took awhile. More than 500 applicants qualified

The first moon landing in 1969 was one of the many historical events that left a question mark in the minds of people. It was also one of the most remarkable and significant events of world history. 1967 was one of the most brutal and bitter years for the Americans. The war in Vietnam up to the assassination of Dr. Martin Luther King‚ the American citizen‚ began to lose hope for their nation. Lyndon B.

Robert H. Goddard: Robert H. Goddard is the creator the first liquid-fueled rocket that has changed the usage and abilities of modern day spacecrafts. Although‚ he wasn’t respected during his engineering process‚ Goddard still strived to follow his dream of one day taking a rocket to the moon. ("Robert Goddard"‚ 2008). Robert H. Goddard invented the first liquid-fueled rocket‚ improving upon the previous basic space crafts‚ despite the extremely negative thoughts society had on his ideas as he started

Introduction A space suit is a garment worn to keep a human alive in the harsh environment of outer space‚ vacuum and temperature extremes. Space suits are often worn inside spacecraft as a safety precaution in case of loss of cabin pressure‚ and are necessary for extra-vehicular activity (EVA)‚ work done outside spacecraft. Space suits have been worn for such work in Earth orbit‚ on the surface of theMoon‚ and en route back to Earth from the Moon. Modern space suits augment the basic pressure garment
