“A bird cannot fly with one wing only. Human space flight cannot develop any further without the active participation of women.” -Valentina Tereshkova Sally Ride was the first American woman in space, launched aboard the space shuttle Challenger in 1983 amidst controversy. At 32, she was the youngest astronaut in history, surrounded by questions such…

“It was a strange lightness, a drifting feeling. Zero gravity. I understood that everything that once seemed solid and immovable might just float away.” -Lisa Unger If you want to experience zero gravity, all you need to do is go to space, turn your rocket off and feel that weightless sensation, right? Except, from up…

“One way or another the first stars must have influenced our own history, beginning with stirring up everything and producing the other chemical elements besides hydrogen and helium. So if we really want to know where our atoms came from, and how the little planet Earth came to be capable of supporting life, we need…

“The very closest stars would require many years to visit, even traveling at the speed of light, which is impossible according to Einstein’s theory of relativity. Today’s fastest spaceships would require 200,000 years to travel to Alpha Centauri, our closest bright star. The energy required to send a hundred colonists to another star, as Frank…

“I’m coming back in… and it’s the saddest moment of my life.” -Ed White, at the end of his first spacewalk A great many of us had dreams of becoming an astronaut when we were younger, and many of us still have that dream today. But turning that dream into reality involves a lot of…

“…axions are potentially detectable through their weak coupling to electromagnetism…” -Aaron Chou We know, from hundreds of years of experience with the laws of physics, that momentum is strictly conserved, and therefore a reactionless drive is impossible. What’s not impossible is an engine that has a reaction that’s simply invisible, or otherwise undetectable to us.…

“The law of the conservation of momentum is the basis of the static thrust equation, the law of the conservation of energy is the basis of the dynamic thrust equation. Provided these two fundamental laws of physics are satisfied, there is no reason why the forces inside the resonator should sum to zero.” -Roger Shawyer,…

“There will be peace when the people of the world, want it so badly, that their governments will have no choice but to give it to them. I just wish you could all see the Earth the way that I see it. Because when you really look at it, it’s just one world.” -Superman So,…

“We are what we are, and we’re doing the best we can. It is not for you to set the standards by which we should be judged.” -Captain Picard, Star Trek: The Next Generation Fifty years ago, on September 8, 1966, the first episode of the original Star Trek premiered. It introduced a vision of humanity’s…

“All of the books in the world contain no more information than is broadcast as video in a single large American city in a single year. Not all bits have equal value.” -Carl Sagan For every action, there’s an equal and opposite reaction. While Newton may not be the final word in mechanics anymore since…
