Astronomy Cast Ep. 707: What Goes Into A Sample Return Mission? Moon & Mars by Fraser Cain & Dr. Pamela Gay Streamed live on Feb 5, 2024. We’ve sent robots to other worlds, but the amount of science we can deploy to another planet can’t compare with the vast science labs we have on Earth. That’s why more and more missions are for a sample return, bringing pieces of alien worlds back to Earth, where we study them with proper equipment.   This video was made possible by the following Patreon members: Jordan Young BogieNet Stephen Veit ( rhymes with right) Jeanette Wink Siggi Kemmler Andrew Poelstra Brian Cagle David Truog Ed David Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela

Astronomy Cast Ep. 706: China’s Space Program by Fraser Cain & Dr. Pamela Gay Streamed live on Jan 30, 2024. We’re so familiar with NASA’s exploration efforts in space, but you might be surprised to learn that China launches almost as many rockets as the US. They’ve got their own space exploration program that could soon bring humans to the surface of the Moon. Let’s give a brief overview of China’s space exploration plans.   This video was made possible by the following Patreon members: Jordan Young BogieNet Stephen Veit Jeanette Wink Siggi Kemmler Andrew Poelstra David Truog Brian Cagle Ed David Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela

Astronomy Cast Ep. 705: Water Worlds - Looking For Life Beyond Earth by Fraser Cain & Dr. Pamela Gay Streamed live January 17, 2024. Wherever we find liquid water on Earth, we find life, so it makes sense to search for water across the Universe, and hopefully we can find evidence of life. But what about worlds which are completely covered in water, oceans hundreds of kilometers deep. Can there be too much water?   This video was made possible by the following Patreon members: Jordan Young BogieNet Stephen Veit Jeanette Wink Siggi Kemmler Andrew Poelstra David Truog Brian Cagle Ed David Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela

NASA’s Juno spacecraft has completed dozens of flybys of Jupiter, seeing the planet from many angles and delivering some of the most beautiful images we’ve ever seen of the Jovian world. Now it’s focusing in on Io, sending home images of the tiny volcanic world from just 1,500 km away. And the best is yet to come.   This video was made possible by the following Patreon members: Jordan Young BogieNet Stephen Veit Jeanette Wink Siggi Kemmler Andrew Poelstra David Truog Brian Cagle Ed David Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela

Astronomy Cast Ep. 702: Moonshot 2024 - Go or No Go? by Fraser Cain & Dr. Pamela Gay Streamed live on Dec 11, 2023. With Artemis 1 completing its robotic flight around the Moon, we know that the SLS works. Next comes Artemis 2, with a crew of astronauts flying past the Moon. If that’s successful, we could see humans set foot on the Moon in December 2025. But there is a long list of challenges to consider that could delay things considerably. Go or no go for launch‽   This video was made possible by the following Patreon members: Jordan Young BogieNet Stephen Veit Jeanette Wink Siggi Kemmler Andrew Poelstra David Truog Brian Cagle Ed Gerhard Schwarzer David Nicholas Cunningham THANK YOU! - Fraser and Dr. Pamela
