When musicians play a lively tune, they often find themselves spontaneously tapping their toes and moving about to the pulsing beat. But when Ellen Ochoa played her flute at work one day in 1993, she couldn’t be spontaneous at all. If she hadn’t made careful plans, she could have been blown about the room, just by playing one long note on her flute. That’s because she was an astronaut working on the U.S. Space Shuttle as it circled Earth more than a hundred miles out in space. Gravity is so weak far out in space that astronauts—and any of their gear that isn’t fastened down—will float about inside a space craft. Blowing air into her flute could have created enough force to actually send Ochoa zipping about the space shuttle cabin. So, to keep herself in place as she played, she had to slip her feet into strong loops attached to the floor. Dr. Ochoa, now the director of NASA’s Johnson Space Center, was the first U.S. astronaut to bring a flute on a space mission, but she wasn’t the first to make music in space. Nearly thirty years earlier, in December 1965, two astronauts onboard the Gemini 6 space craft played a musical joke on mission control officials down on Earth. Those astronauts—Walter M. Schirra, Jr., and Thomas P. Stafford—told mission control that they saw an unusual object near their spaceship, a satellite perhaps, moving from North to South. They said they would try to pick up some sound from this mysterious object. Then they used the harmonica and bells they had secretly brought with them on that December mission to surprise folks listening down below by playing “Jingle Bells.” In recent years, other astronauts have brought musical instruments on space missions to help lift their spirits, especially those who spend many months on the International Space Station. Like Dr. Ochoa, these astronaut musicians have to make adjustments, such as using a bungee cord to attach an electronic piano keyboard to a pianist’s leg. Some astronauts have composed music in space, including Canadian Chris Hadfield. On May 6, 2013, he sang the song he wrote—called “I.S.S. (Is Somebody Singing)”—in a live TV broadcast from the space station as thousands of Canadian schoolchildren sang along with him down on Earth.

Do you ever feel spaced-out before you take a test? Yes or no, let’s go! 1. TRUE or FALSE? It’s possible for a spacecraft to fly from Earth to Venus, to Mars, back to Earth, then to Saturn, out to Pluto, back to Jupiter, and come home to Earth on one tank of fuel. 2. It’s possible for a spacecraft to fly all over the solar system on one tank of fuel because of: a. the sling-shot effect b. gravity assist c. swing-by d. all of the above e. none of the above The sling-shot effect, also known as a swing-by or gravity assist, is used to accelerate a spacecraft. Acceleration means to change the speed and/or the direction of a moving body. A spacecraft that is speeding up, slowing down, or following a curved path is accelerating. Gravity accelerates objects everywhere in the Universe. When you ride your bike up a hill it takes a lot of effort to make it to the top because the Earth is massive compared to you, and gravity pulls you toward its center. When you coast down the other side, gravity is your friend! Spacecraft can use the gravity of a planet to accelerate. Picture a spacecraft falling toward a planet. The spacecraft will crash unless it steers away. 3. As a spacecraft accelerates toward a planet, the motion of the planet is also affected by the gravity exerted by: a. the spacecraft b. the Sun c. cosmic rays d. both (a) and (b) e. both (b) and (c) f. all of the above g. none of the above All bodies in space, no matter how big or small, exert gravity on each other. Planets stay in orbit around the sun because of gravity. A planet is also affected by the tiny mass of a spacecraft. Gravity assist was used to increase the speed of Voyager 1 by 36,000 mph on its swing by Jupiter, which sling shot it to Saturn. And Jupiter slowed down infinitesimally, at a rate of 12 inches per one trillion years. 4. The person who discovered the math for using gravity assist to accelerate a spacecraft from planet to planet to planet…was: a. Aristotle (384 B.C. to 322 B.C) b. Galileo (1564-1642) c. Sir Isaac Newton (1643-1727) d. Katherine Johnson (1918- ) e. Michael Minovitch (1936- ) END OF TEST! DON’T STOP WORKING. START TALKING. ASK QUESTIONS. GO TO THE LIBRARY TO FIND THE ANSWERS.

 In 1983, shortly before she became America’s first female astronaut to participate in a mission, Sally Ride faced a press conference. Reporters raised questions they would never have asked a man. “Will the flight affect your reproductive organs?” one inquired. “Do you weep when things go wrong on the job?” queried another. A third wondered, “Will you wear makeup and a bra in space?” Tonight Show host Johnny Carson joked that the flight was delayed because Sally had to find a purse that matched her shoes. It wasn’t just U.S. media. The Soviet Union had already sent two women into space. When one of them arrived at the space station, a male cosmonaut (the Soviet term for astronauts) said, “An apron is waiting for you in the kitchen.” By this point, Sally had mastered parachute jumping, water survival, coping with weightlessness and the massive G-forces from a rocket launch, and other highly demanding skills. She flew jet planes. She had a Ph.D. degree in physics from Stanford, one of the nation’s top universities. She helped develop a robotic arm for use on the space shuttle. She was a nationally ranked tennis player who decided not to turn pro because she preferred science. The general public seemed more accepting. On launch day at Florida’s Cape Canaveral, thousands of people wore “Ride, Sally, Ride!” T-shirts, from the lyrics of the pop song “Mustang Sally.” The mission went flawlessly, and Sally flew again the following year. She was scheduled for a third flight in 1986, but it was scrubbed when the Challenger space shuttle blew up. Sally left the space program soon afterward. She was passionate about encouraging young people—especially girls—to become involved in STEM (Science, Technology, Engineering, Math). Here are some of the things she did toward that achieving that goal.
Sadly, Sally Ride died of cancer in 2012 at the age of 61. Shortly afterward, President Barack Obama awarded her the Presidential Medal of Freedom. It is the nation’s highest civilian honor.

In spring 1665 a college student named Isaac Newton studied natural philosophy, what we call “science.” Back then, a good student could learn everything to know about the natural world. But plague, the Black Death, came to England. Cambridge University closed. Isaac went home to Woolsthorpe. For two years Isaac thought about his studies during four years at university. He’d always been thoughtful—not the best at games, making friends, or minding sheep. But everybody knew Isaac Newton liked to think. Folks told time by the sundial he’d drawn on a wall. Home at Woolsthorpe, Isaac’s learning about science and math bubbled up in his head like yeast rising in a loaf of bread. So... Newton unplugged. His mind roamed like that of an artist or composer. He was driven by the need to create—not paintings or symphonies, but questions. “Why do things always fall down?” “Why does the earth move around the sun? “Why doesn’t the moon fall onto the earth?” “Does everything ‘up there” work like things work ‘down here?’” Isaac Newton answered his questions with three science rules, Newton’s Laws of Motion. At Woolsthorpe, Newton grappled with the concept of moving objects. He worked out the math to find the area under curves. He called this math fluxions. Today we call this calculus, useful for launching rockets or tracking TV signals. Once back at Cambridge, Newton said nothing until he read someone else’s paper on fluxions. Newton published a better paper. Soon he was Cambridge’s top math professor. Isaac Newton wondered another twenty years. He played with prisms in a dark room and theorized that white light comprises the visible spectrum of red, orange, yellow, green, blue, indigo, and violet. He practiced alchemy and chemistry, looking for the legendary philosopher’s stone to turn base metals to gold. In 1687, Newton published our most important science book, the Principia. In the Principia, Newton showed how laws of gravity and motion work the same at great distances—far off in space, or in your classroom. We accept these ideas, but in 1687 many still had medieval beliefs that sun, moon, planets, and stars all traveled in their own crystal spheres. Yes, Newton wondered about A LOT:
