During Artemis II, four astronauts will see the lunar surface as few humans have—and possibly, parts of the Moon’s far side that no one has seen before. Learn what lunar science questions NASA hopes to answer through the astronauts' eyes with lunar geologist Kelsey Young. And those astronauts will also be subjects of science. Jancy McPhee, associate chief scientist of NASA’s Human Research Program, explains how studying human health on Artemis II will prepare us for exploration deeper into space than ever before.

During Artemis II, humans will fly Orion—NASA’s next-generation spaceship designed to take us to the Moon and beyond—for the first time. Tour Orion with Branelle Rodriguez, the vehicle manager for Artemis II, to hear about the support systems that keep astronauts alive and how exactly you use the bathroom en route to the Moon. Then, pop the hood of NASA’s most powerful rocket, the Space Launch System, with David Beaman, one of its key architects.

In 2022, NASA launched Artemis I, an uncrewed test flight of the rocket and spacecraft that will send humans to the Moon. Go inside Firing Room 1—the nerve center for Artemis launches—and hear from the engineers who launched Artemis I, including the intricate procedures they developed just to fuel the rocket correctly. Now NASA is ready to launch Artemis II—and to send humans around the Moon.

This year, four NASA astronauts will fly around the Moon and back for the first time since the Apollo program. Their mission is called Artemis II. It’s a key test flight that will set the stage for Artemis III, when humans land on the lunar South Pole for the first time and set up a long-term presence there. In this episode, meet your intrepid Artemis II crew: commander Reid Wiseman, pilot Victor Glover and mission specialists Christina Koch and Jeremy Hansen.

The James Webb Space Telescope is doing something astronomers dreamed about for decades: peering into our universe’s early past, a period known as cosmic dawn. A new NASA documentary—also called Cosmic Dawn—chronicles the inside story of Webb’s design, construction, and launch. John Mather, who won the 2006 Nobel Prize for Physics, proposed the telescope and led its science team for decades. In this interview, Mather talks about his life, his research, and the pre-dawn phone call telling him he had won the Nobel Prize.

Have you ever dreamed of spending a day in space? Humans have lived aboard the International Space Station for 25 years—or more than 9,000 consecutive days. In this episode originally published in 2021, experience a day in the life of astronauts Shane Kimbrough, Megan McArthur, and Thomas Pesquet living and working on the International Space Station. 

In the space between stars, dark clouds of gas, dust, and ice mingle in a chemical laboratory unlike any on Earth. Ewine van Dishoeck, an astronomer who studies molecules in space and who helped develop an instrument aboard NASA’s James Webb Space Telescope, explains how Webb is revealing new details about the formation of stars and planets. This research could help unlock a key question about Earth: how did our planet end up with water and the ingredients for life? 

NASA’s James Webb Space Telescope is hard at work answering our biggest questions about the birth of our universe and faraway galaxies. But some astronomers are pointing its powerful eyes much closer to home. In this episode, Caltech astronomer Katherine de Kleer explains how Webb is rewriting our understanding of objects within our solar system–from space rocks in the asteroid belt to the icy and volcanic moons of Jupiter and Saturn.

Some exoplanets—like a gas giant with rain made of glass and 5,000-mile-per-hour winds—sound like worlds dreamed up by a science fiction writer. But they’re real. From light-years away, scientists can uncover details about planets orbiting distant stars and even ask whether some exoplanets could support life. Néstor Espinoza, an astronomer at the Space Telescope Science Institute, explains how NASA’s James Webb Space Telescope is revealing new details about exoplanets, especially rocky worlds like Earth.
