The Saturn 5 was a monster, capable of sending humans and a lander to the Moon and bringing them back again. But the number of heavy lift rockets since then has gotten pretty sparse. Now, with tens if not hundreds of thousands of satellites in the works, giant new space telescopes and multi-ton lunar landers in development there are heavy lift solutions to match. So let’s talk about them! From yesterday's Saturn V to today's Ariane VI, rockets capable of launching large telescopes or small space stations in a single go are modern marvels. They are also wildly dangerous, and not exactly compatible. Let's look at today's fleet of rockets and just what they're accomplishing.

Well, we’re just a couple of weeks away from summer hiatus and so it’s time to give you some homework. Here’s our list of stuff we’ve been reading watching and playing. This should fill the Astronomy-Cast-shaped hole in your media landscape. On the plane, on the beach, from the passenger seat in a car, summer is a time for escaping into a good book, video, or game. From classics to the latest releases, here are our recommendations for keeping your brain occupied while your body is renewed.

We’re about to take a much needed 2 month hiatus. But just because we’re not here doesn’t mean space stops existing and doing things. Today, let’s give a preview of the big events due to happen in space this summer so you can prepare yourself and make sure you don’t miss a thing! From meteors to moon landings and more, join Fraser and Pamela as the look at what you can enjoy this summer, after we go to hiatus in July.

Mars is cold & dry today, but the evidence is growing that it used to be warmer & wetter. with seas & oceans that covered large parts of its surface. With the additional findings of the chemicals for life, the search for life on Mars is getting pretty interesting! New results from Perseverance and Curiosity describe a past Mars with complex chemistry and water. But did it have life?

Today we continue our mini-series; evaluating the science of various sci-fi franchises. We did Star Wars last week, this week tackle Star Trek. From transporters to warp drives, from phasers to photon torpedos. Let’s tackle what Star Trek gets right and wrong about science. Let's look at the science of our galaxy, some day far in the future.

May the fourth be with you! Isn’t that what people say on the international holiday known as Star Wars Day? Today we’re gonna talk about the science in everyone’s favorite sci-fi fantasy stories. Which of it is real, and which is essentially magic? Let’s find out! Let's look at the science of a galaxy long ago and far away. (Did you just hear the theme music in your head? We heard it start in our head!)

Last week we talked about samples from other worlds delivered to Earth by meteorites. But sometimes you’ve gotta do the job yourself. Visit the far off place and bring the samples home. And today we’re gonna talk about China’s Chang’e sample return program. How they’ve delivered rocks from different parts of the Moon, and how this sets the stage for their upcoming human lunar missions. 

The Chinese space program is step by step testing the technologies necessary for humanity to return to the surface of the Moon. From orbiting comms satellites, to landing sample return missions, the Chang`e missions are exploring new places in new ways. In today's episode, we discuss the Chang`e 6 sample return.

Even though humanity has returned samples from a fraction of the worlds in the solar system, the cosmos has delivered many more without us having to lift a finger. Meteorites. We have meteorites from the Moon, Vesta and even Mars! What have we learned about these rocks from other worlds? Space missions to other worlds cost millions to billions of dollars, and if we want to know exactly where space rock samples come from, we need to spend the big bucks for sample return. But, if it's good enough to know "this rock came from somewhere on that world," space offers an amazing delivery system in the form of meteorites. Come learn about the search for, identification, and science of meteorites from other worlds.
