Human Space Flight Quotes & Sayings

Three years after the United States ended the space shuttle program, the American space agency today announced the return of "human space flight to U.S. soil." NASA has chosen two spaceships, the Boeing CST-100 and SpaceX Dragon version 2, to bring American astronauts to the International Space Station. The program will cost $6.8 billion. — Anonymous

Politicians and the government have become too interested in short-term gains. Of course, if you look at the direct financial returns in the short term, human space flight is expensive. But they need to look longer term. — Helen Sharman

The single simplest reason why human space flight is necessary is this, stated as plainly as possible: keeping all your breeding pairs in one place is a retarded way to run a species. — Warren Ellis

Retain the vision for space exploration. If we turn our backs on the vision again, we're going to have to live in a secondary position in human space flight for the rest of the century. — Buzz Aldrin

Basically, most good science in space flight has to do with the behavior of the human body in space. That is where we are lacking info, and where info can only be obtained by flying in space. — Charles Simonyi

Other anatomical changes associated with long-duration space flight are definitely negative: the immune system weakens, the heart shrinks because it doesn't have to strain against gravity, eyesight tends to degrade, sometimes markedly (no one's exactly sure why yet). The spine lengthens as the little sacs of fluid between the vertebrae expand, and bone mass decreases as the body sheds calcium. Without gravity, we don't need muscle and bone mass to support our own weight, which is what makes life in space so much fun but also so inherently bad for the human body, long-term. — Chris Hadfield

In this age of space flight when we use the modern tools of science to advance into new regions of human activity, the Bible ... remains in every way an up to date book. Our knowledge and use of the laws of nature that enable us to fly to the moon, also enable us to destroy our home planet with the atom bomb. Science itself does not address the question whether we should use the power at our disposal for good or for evil. The guidelines of what we ought to do are furnished in the moral Law of God. — Wernher Von Braun

I'll tell you, being involved in human space flight, it is an emotional endeavor. I think it brings in the highest highs and the lowest lows. — Ellen Ochoa

I believe that the time has arrived for medical investigation of the problems of manned rocket flight, for it will not be the engineering problems but rather the limits of the human frame that will make the final decision as to whether manned space flight will eventually become a reality. — Wernher Von Braun

One of the major problems with long-term deep space human flight is the requirement for radiation shielding. — Buzz Aldrin

A bird cannot fly with one wing only. Human space flight cannot develop any further without the active participation of women. — Valentina Tereshkova
