Ep. 629: The Cost of Delays
With all the success of James Webb so far, it’s looking like science’s huge gamble is going to pay off, but there were years of delays and budget overruns. What impacts did these delays have on science, careers, and the future of space exploration?
Ep. 628: The Sun Revisited
Once again, it’s time to take a look at the Sun. You know, ongoing thermonuclear explosion of fusing hydrogen that’s right over there. Fortunately, there’s a fleet of spacecraft and ground observatories ready to give our best ever view of the Sun.
Ep. 627: Mercury Revisited
It’s been about a thousand years since we last looked at Mercury, so we figured it’s time for an update. What new things have we learned about Mercury, or even new questions? Fortunately, there’s a mission on the way to help get us some answers.
Ep. 626: Terrestrial Planets — Mercury, Venus, Earth, and Mars
We continue our refreshed tour of the Solar System, checking in on the inner terrestrial planets: Mercury, Venus, Earth and Mars. What have we learned about their formation, evolution and what they might tell us about other planets in the Universe?
Ep. 625: End of the Year Review
We’ve reached the end of 2021, and this is the last episode of the year. Let’s look back at the big space events of the last year and talk about what we’re looking forward to in 2022.
Ep. 624: Small Rocky Bodies (Including Phobos and Deimos)
We’ve talked about the icy objects of the Solar System, today let’s talk about space rocks. There’s a surprising variety of rocky material in the Solar System, and each object has a story to tell about the history and formation of the planets, moons and other rocky bodies.
Ep. 623: NEOS: Concern or Nah?
Are asteroids dangerous? Just ask the dinosaurs, and they’ll tell you a sad story of fiery death. It turns out we’re in a shooting gallery of space rock and metal, and somewhere out there there’s one with our name on it. Should we be worried or are the risks so minimal to be irrelevant?
Ep. 622: Rocky Moons and Giant Asteroids
A rock is a rock is a rock, right? Across the Solar System there are giant rocky asteroids and even rockier moons. What’s the difference between these two families of objects, and where did they come from?
Ep. 621: Gas Giants
For the longest time, the only gas giant planets we knew about were Jupiter and Saturn. But now in the age of extrasolar planets, astronomers have discovered thousands of gas giants across almost as many star systems. What new discoveries have been made about gas giants, both here in the Solar System and across the Milky Way?
Ep. 620: Why Getting to the Outer Worlds is So Difficult
Good news! Over the next few years, we’re going to see a flotilla of new missions headed to Jupiter and Saturn. Why aren’t we seeing more missions to the outer planets, like Uranus and Neptune? It turns out, those places are far away. Today let’s talk about the challenge of exploring the outer Solar System.
