NASA scientists now know more about how space travel affects the human body. They were able to study the genes of identical twins. One who went into space for a year and one who stayed on Earth. Since they share the same DNA profile, scientists had a chance to study changes to their bodies as well as changes to their DNA. The study showed that genes do change in space and remain changed even months after returning to Earth. Listen to learn more about how space travel can change human DNA.

Scientists have discovered evidence of gravitational waves, which show ripples in space and time. A new machine has made it possible for scientists to observe space in a whole new way. Recently, the machine picked up vibrations from the collision of two black holes. The discovery comes a few months after the very first detection of gravitational waves. With these tools, scientists can look at the universe in a new way. In this story you will hear the signal from the black holes converted from gravitational waves to soundwave.

NASA is preparing to launch a spacecraft that will measure and report space weather and provide live images of Earth. The idea to provide Earth’s images for the public to view started with former Vice President, Al Gore, in 1992. He believed everyone should be able to view and study the earth. The satellite’s ability to measure space weather will help prevent against damaging effects on earth from things like solar storms that can damage electric power grids. After more than a decade, Gore’s vision is becoming a reality. Listen to hear more about this new satellite.

Scientists recently made an exciting discovery. They spotted three, earth-sized planets beyond our solar system. Though scientists have found many planets in the past, these particular ones are special because they may potentially support life. They each orbit a reddish “dwarf star” that is smaller than our sun and much cooler. Scientists used to ignore these dwarf stars, but now we know that such stars can produce planets worth studying. Scientists will continue to analyze these planets to find out more about their atmospheres and properties. Listen to hear more about these three newly-discovered worlds.

Astronauts live and work in small spaces. If they were to stay in space for years at a time, they would need a larger place to live. The problem has been how to pack something large into a small space capsule. The solution may be an inflatable room. NASA is now ready to test a new inflatable habitat. It will be sent to the International Space Station for a trial. Listen to hear more about this invention.

After living in space for almost a year, NASA astronaut Scott Kelly returned safely to Earth. Kelly stayed aboard the International Space Station, conducting experiments and taking photographs of Earth. Throughout the year, he was able to communicate with people at NASA and update them on his activities and status. Researchers at NASA have also tracked Kelly’s physical and mental health after one of the longest missions in space. Listen to the story to hear more about this astronaut’s admirable and historic journey.

This story is about astronaut Ronald McNair, as told by his brother Carl. They grew up in racially-segregated South Carolina. Carl tells about when Ron came up against segregation laws that he didn’t understand as a child and how that shaped his life as a young African-American in the rural south. But his life ended tragically. Listen to this story of Ronald McNair’s journey.

Every spring and fall Americans turn the clocks back or forward one hour to make the best use of the daylight. It’s called Daylight Savings Time. When the clocks are turned back in the fall, it will be brighter in the mornings as we go to school and to work. New research shows this time change has a big downside: an increase in crime. By looking at crime patterns, researchers discovered that robbery rates increase when it's darker for a longer time in the evenings. Listen to this story and have students gather evidence for a debate about whether or not we should keep Daylight Savings Time.

NASA's Mars Reconnaissance Orbiter shows dark streaks flowing down Martian slopes. When the streaks are widest, there is evidence of water molecules. When the streaks shrink in the cold, water disappears. The water is not the same as a stream on Earth, but more like a hint of wetness. Although scientists are not entirely sure where the water source is, they say it could be from a salty underground reservoir or soaking up moisture from the atmosphere. Listen to hear how water can be important for future explorations on Mars.

Individuals who make extraordinary contributions to science often begin as regular people with a passion. This was certainly the case for Alan Guth, the physicist responsible for our understanding of how the universe formed after the Big Bang. Guth’s love for physics was sparked in high school and continues to drive his work today as a professor at MIT. Listen to learn more about his journey from a small town in New Jersey to physics textbooks around the world.

Gravity keeps our feet on the ground, it creates a curve ball, and it can also be used to find new planets. The star at the center of our solar system maintains life on Earth and its gravitational pull creates the orbit of planets. But our sun is just one of many stars in an ever expanding universe. Alpha Centauri is the closest star system to our solar system and new technology is allowing us to better understand our neighbor. Observations of Alpha Centauri date back to 1592, but it wasn’t until 2012 that astronomers in Chile were able to identify a planet orbiting one of the stars in Alpha Centauri because of its gravitational wobble. Listen to learn more about the properties and potential of this new planet.

In 2024 crews of four will be sent to Mars with the goal of creating a permanent human settlement there. The mission is being planned by a non-profit organization in the Netherlands called Mars One. 200,000 people applied to be one of the first four people to make this all expense paid trip. Mars One has narrowed the applicants down to 100. Shirelle Webb, a 22 year old college student from Texas has made the cut. Listen to learn why she wants to be considered for the one-way trip.
Current Event February 24, 2015
The sun is a star that sits at the center of our Solar System. It provides heat and a gravitational pull for all of the planets that orbit it. Scientists have long believed they knew what the sun was made up of and how it worked. When new evidence upset the balance between theory and observation, a solar physicist set out to reproduce the way the sun functions in a laboratory. Listen to hear more about how the sun works.

It is difficult to conceptualize the magnitude of our solar system but the journey of the Voyager spacecrafts can help. In September 1977 NASA launched the Voyager spacecrafts to gain information about the far off giant planets in our solar system. The spacecrafts and the project endured after studying Jupiter, Saturn, Uranus and Neptune and continued to travel away from earth and through our solar system. Thirty-five years after Voyager 1 left Earth, and over 11 billion miles away, it became the first man-made object to leave our solar system and enter interstellar space. Listen to learn what researchers have been researching from the edge of our solar system.
