Por NASA Podcast #Recomendado Tweet Gravity Assist: It’s Raining Diamonds on These Planets Uranus and Neptune are two of the many exciting and mysterious objects in our universe that the James Webb Space Telescope will soon begin to explore. Temperature and pressure conditions are so extreme on these planets that carbon atoms could be crushed into diamonds in their atmospheres. And did you know that Uranus orbits on its side? Learn more about these planets and the Webb telescope’s upcoming observations from astrophysicist Naomi Rowe-Gurney, our guest on this week’s Gravity Assist.

Por NASA Podcast #Recomendado Tweet Gravity Assist: Meet a Space Weather Scientist, with Yaireska Collado-Vega Our Sun lights up the solar system, but it’s as not calm or predictable as it may seem. Flares and explosions called coronal mass ejections unleash fast-moving particles and radiation that pose dangers to spacecraft and astronauts alike. Yaireska Collado-Vega leads a team at NASA’s Goddard Spacecraft Center that is studying the solar weather environment so that robots and people exploring space can be protected. In this episode of Gravity Assist, she describes the excitement and challenges of understanding space weather, and how she got to be a NASA scientist.

Por NASA Podcast #Recomendado Tweet Gravity Assist: The History of the Future, with Steven Dick People have long wondered whether there is life beyond Earth, but it is only recently that scientists have been able to apply the tools of space exploration to go after this question. In 1996, the Allan Hills 84001 Meteorite shook the world as scientists debated whether it had tiny fossils inside of it that came from Mars. The consensus is that this rock does not contain Martian fossils, but the questions it raised energized many researchers. Today, the field of astrobiology is looking at how life arose on Earth and where else in the solar system and beyond life could exist. Beyond these scientific investigations, there are also philosophical questions one could ask. Would we be ready as a society for such a groundbreaking discovery? Astronomer and historian Steven Dick tells us there are many approaches to consider and many questions we should ask ourselves to get ready, in case extr...

Por NASA Podcast #Recomendado Tweet Gravity Assist: The Moon's Holy GRAIL, with Maria Zuber Neil Armstrong and Buzz Aldrin landed far from where they had anticipated because, 50 years ago, we didn't have a complete understanding of the Moon's gravity. Recent maps of the Moon's gravity have taught us a lot about its overall shape, and have been invaluable for lunar exploration. Maria Zuber, principal investigator of NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission, reflects on the twin spacecraft and their implications for future investigations.​

Por NASA Podcast #Recomendado Tweet Gravity Assist: The Moon Quakes! With Walter Kiefer Just like earthquakes help scientists figure out what's going on inside our home planet, moonquakes have taught scientists a lot about the interior of the Moon. NASA's Gravity Recovery And Interior Laboratory (GRAIL) mission has also given us a clearer picture of the Moon beneath its surface. Seismic activity on the Moon is one area of scientific interest as NASA makes plans to send the first woman and the next man to the Moon by 2024.

Por NASA Podcast #Recomendado Tweet Gravity Assist: When the Moon Was Like a Magnet, with Sonia Tikoo From lunar samples brought back in the Apollo program, scientists have figured out that the Moon once had a shield around it called a magnetosphere, just like the Earth has today. As NASA prepares to send humans to the Moon, and eventually on to Mars, scientists are exploring the Moon's magnetic past.

Por NASA #Recomendado Tweet Gravity Assist: The Sun’s Mysteries with Thomas Zurbuchen Back in August, NASA launched the Parker Solar Probe to study the Sun’s corona—its very outer edge. Parker will sail as close as 4 million miles from the Sun—a record for any space agency in the world—and survive temperatures up to 2,500 degrees Fahrenheit. In this week’s episode of Gravity Assist, Thomas Zurbuchen, the Associate Administrator of NASA’s Science Mission Directorate, joins NASA Chief Scientist Jim Green to discuss the mysterious we still need to solve about the Sun, and more! https://ift.tt/2UzVTfA via IFTTT
