As Spaceship Earth transports us through space at an orbital speed of over sixty thousand miles per hour there is a debate over the destination of mankind’s next deep space conquest. Some propose that we go back to the Moon to reap its mineral wealth and establish colonies to pave the way for further steps to deep space. Twice since the cancellation of the Apollo lunar program NASA has tried to revive the return to the Moon goal and failed. Today NASA is preparing for sending humans to the planet Mars. That goal is also failing. It’s been nearly fifty years since mankind left the Moon and today we don’t even have the capability to send our astronauts to the space station.This book presents a paper trail of letters and emails that disclose why our human space endeavors always end on a trajectory to cancellation. It also provides solutions made by concerned American aerospace engineers and the ominous warning of another deadly space disaster. The reader is challenged not to remain silent after reading The NASA Letters.
