How Lying In Bed For 60 Days Helps Astronauts

How Lying In Bed For 60 Days Helps Astronauts

In space, microgravity changes the body. Body fluids shift from the legs toward the head, the back of our eyes flatten, we lose muscle strength, our bones lose some of their density, and even the amount of blood pumped by the heart with each beat drops. To learn more about how microgravity affects the human body and develop new ways to help astronauts stay healthy, scientists are asking dozens of volunteers to spend 60 days in bed with their heads tilted down at a specific angle. This research approach tricks the body into reacting very similarly to how it would if a person was aboard the International Space Station for a longer-term mission. Join Andreas Joshi, a volunteer who agreed to be part of this bedrest work, and two NASA scientists leading the study. They’re investigating different ways to combat space-based muscle loss and improve astronauts’ sense of balance by, among other things, teaching volunteers like Joshi to play video games with their feet.

Why the Moon’s Icy South Pole is a Hot Target for NASA

Why the Moon’s Icy South Pole is a Hot Target for NASA

The Moon’s South Pole is a bizarre landscape. Mountain ridges glow in perpetual sunlight while deep craters freeze in billion-year-old shade. Yet hidden in the depths of those shadowed craters, under temperatures almost three times colder than the frostiest day in Antarctica, lurks something familiar–water ice. In the future, that ice could sustain human explorers or be broken apart into hydrogen and oxygen to refuel rockets. Join Brett Denevi, Artemis III geology team lead, to learn why NASA plans to land astronauts on the Moon’s South Pole later this decade. Then with Michelle Munk, NASA space technology chief architect, meet the robot Moon landers scouting ahead of Artemis which will drill beneath the regolith and test technologies designed to help future human explorers survive the Pole’s extreme conditions.

Europa Clipper's Voyage to Jupiter's Ocean Moon

Europa Clipper's Voyage to Jupiter's Ocean Moon

As NASA’s Europa Clipper spacecraft leaves Earth, it carries a message: we, too, are made of water. Europa—one of Jupiter’s moons—is a top candidate to support life, thanks to its ocean of liquid, salty water capped by a layer of ice. Lynnae Quick-Henderson, a planetary scientist at NASA, explains how Clipper will search Europa for the building blocks of life. The mission is also a message in a bottle, bringing a greeting from one ocean world to another. Hear how Ada Limón, the Poet Laureate of the United States, used NASA’s mission as inspiration for her poem “In Praise of Mystery: A Poem for Europa” and why she thinks everyone—even space nerds—should step back and appreciate our connections to the universe and each other.

An Asteroid by Any Other Name With Special Guest Latif Nasser

An Asteroid by Any Other Name With Special Guest Latif Nasser

The idea of an asteroid from outer space crashing into Earth has captured the imaginations of science fiction directors for decades. But here at NASA, we take potentially hazardous near-Earth objects seriously. We have a planetary defense office that plans for every scenario—we’ve even practiced nudging an asteroid off course with spacecraft. But there are tens of thousands of objects in near-Earth space, and the first step in protecting against potential impacts is spotting, tracking and managing every single one of them. Learn how NASA does just that from Joe Masiero, a scientist on the asteroid survey mission NEOWISE. Then, join friend of the show Latif Nasser, co-host of the podcast Radiolab, to untangle the mystery of a strange space rock that’s not quite a moon but not quite a normal asteroid, either.

Sun Series: You (Yes, You!) Can Help NASA Study the Sun

Sun Series: You (Yes, You!) Can Help NASA Study the Sun

How often do you think about your nearest star? Though it may not seem like it from here on Earth, our trusty Sun is a place of mystery. Take a good look at its influence on our planet – through the otherworldly experience of eclipse, maybe, or the aurora – and you might get "sucked" in... to a citizen science project, that is. Join NASA Sun scientists like Liz Macdonald and volunteers like Hanjie Tan to listen to crickets fooled by the false night of an eclipse, discover new colors in the aurora, and hunt for comets hiding in the plasma of our Sun’s atmosphere. And learn how you can get involved in NASA science while experiencing our nearest star firsthand. This is episode three of the Sun and Eclipse series from NASA’s Curious Universe, an official NASA podcast.
