12-Extinctions: Space station splashdown

The International Space Station feels like a permanent fixture. It’s been up there since 2000! But earlier this year, NASA announced it is bringing the ISS back to earth in the 2030s as it plans for new space stations.

3-True story: A Martian on Earth

Tanya Harrison never thought she was going to be an astronaut. But she was determined to go to space. And she did just that – through satellites, first to Mars, and now looking back at our own third rock from the Sun as she uses satellites to map places near and far. We talked with her about what it’s like to be a Martian, making science more accessible to those …

Third Pod Presents: Stereo Chemistry – Searching for Mars’s missing water

More than 50 years of missions to Mars paint a clear picture of a cold, dry, desert planet. And at the same time, photographs, minerals, and other data tell scientists that Mars once had as much water as Earth, or even more. Why are the two planets so different today?

What’s It Like Pretending to Live on Mars?

If someone offered you the chance to drop everything, fly to Hawaii, and spend four months trapped in a dome with seven strangers in the name of science, would you do it? For writer Kate Greene, the answer to that question was a resounding “yes.” Greene was one of eight people selected to crew the very first HI-SEAS Mars analogue mission in 2013.

A Modern Way to Look for Aliens

If you were an ant living in an anthill in the Serengeti and you wanted to know whether an intelligent species lived on planet Earth, how could you tell? A particularly clever ant might pick up a radio signal and deduce that humanity exists, but how about subtler, indirect clues that, nevertheless, are a result of technological development?

From Athlete to Astronaut

Leland Melvin’s scientific career began during his childhood in Lynchburg, Virginia, when he created a fantastic explosion in his living room with an at-home chemistry set. Little did Leland or his family know at the time that he would become both a professional athlete and a NASA astronaut, flying two missions to the International Space Station.

Final Frontier? The Evolution of Planetary Science Missions

The latest episode of Third Pod from the Sun features an interview with planetary scientist Fran Bagenal, who has had a fascinating career working on NASA missions from Voyager to Juno and New Horizons. Currently working at the University of Colorado Boulder, Bagenal provides an overarching view of the different planetary missions going back a few decades and describes how the research and findings have built upon the innovations and discoveries that came before.

Earthrise

On 24 December 1968, humans witnessed our home planet rise over the horizon of another world for the first time. The crew of Apollo 8 looked up from the Moon to see the blue and white swirls of Earth poised above the stark grey lunar surface—a single oasis in a big, dark universe.

Final images from Cassini spacecraft

For the last leg of its journey, Cassini was put on a particularly daring orbit passing between Saturn and its rings which brought it closer to Saturn than ever before. This allowed scientists to obtain images of Saturn’s ultraviolet auroras in unprecedented resolution. The new observations are detailed in two new studies published in the AGU journals.

Forces from Earth’s spin may spark earthquakes and volcanic eruptions at Mount Etna

A new study suggests that polar motion and subsequent shifts in Earth’s crust may increase volcanic activity. “I find it quite exciting to know that while climate drives Earth’s spin, its rotation can also drive volcanoes and seismicity,” said Sébastien Lambert, a geophysicist at Paris Observatory in France and lead author of the study. The new findings, however, don’t allow scientists to forecast volcanic activity.

Third Pod Presents: Sci & Tell – Lori Glaze on Nudging Asteroids

It’s no exaggeration to say Lori Glaze’s impact on our understanding of the relationships between Earth and our nearest neighbors is volcanic. In fact, eruptions fascinated her since she was a pre-teen learning about the destructive volcano which buried the Roman city of Pompeii or carefully scraping ash from the Mount St. Helens eruption off the hood of the family car in Seattle in 1980.

Newfound Martian Aurora Actually the Most Common; Sheds Light on Mars’ Changing Climate

A type of Martian aurora first identified by NASA’s MAVEN spacecraft in 2016 is actually the most common form of aurora occurring on the Red Planet, according to new results from the mission. The aurora is known as a proton aurora and can help scientists track water loss from Mars’ atmosphere.

E23 – Between a Varnished Rock and a Hard Place

Scientists have been testing whether life exists on Mars for over 40 years, ever since the Viking 1 lander touched down on the Red Planet. Researchers often perform experiments on Earth to better understand the context of data collected by Viking 1 and subsequent landers – data that gives scientists tantalizing clues about the habitability of the Martian surface.

E22 – Diamond Anvils and the Heart of Jupiter

Physicist Marius Millot investigates the intimate atomic worlds of elements in order to understand the inner secrets of the largest planets in our solar system. Jupiter and its fellow gas giants Uranus, Neptune and Saturn are comprised mostly of the lightest element, hydrogen, with a dab of helium, heavier elements, and more complex molecules. But researchers want to know what lurks at the planet’s core, under all that cloud.
