Ep. 688: What’s Next? Looking Ahead to Season 17

Once again, we’ve reached the end of a season here on Astronomy Cast, and it’s time for the summer hiatus. But the Universe never takes a break. What can we expect to happen over the summer while we’re catching up on our reading, building our gardens and planning for Season 17

Ep. 687: Prepping for the Moon

Ep. 687: Prepping for the Moon

We’re going back to the Moon. In the next few years humans will set foot on the Moon again, ideally this time to stay. But this will be different than the Apollo era, going to the scientifically fascinating, and difficult southern pole of the Moon. What needs to be done to prepare the way back to the Moon?

Ep. 686: Ice in the Shadows

Ep. 686: Ice in the Shadows

The permanently shadowed craters on the Moon are the focus of so much research. That’s because they seem to contain vast reserves of water ice. Water we could use for oxygen, propellant and so much more, but also, to help us understand where the Earth’s water came from.

Ep. 685: Manufacturing in Space

Ep. 685: Manufacturing in Space

Launching satellites from Earth is counter-productive. You’ve got to make a satellite that can handle Earth gravity, then the brutal flight to space, then deployment in orbit. What if you could build your spacecraft in space?

Ep. 673: How to See Satellites (or Avoid Seeing Them)

Ep. 673: How to See Satellites (or Avoid Seeing Them)

If you’re in dark skies and look up, you’re certain to see a satellite. Lots of them. But how can you know which one you’re seeing, and how can you improve your chances of a sighting? Today we’ll talk about how to see satellites, or avoid seeing them.

Ep. 672: Space Debris Removal

Ep. 672: Space Debris Removal

We’ve talked about the rising problem of space junk. Okay, we know it’s an issue. So what can be done about it? Today we’ll talk about ideas to remove space junk, making sure space is open to use for the centuries to come.

Ep. 671: The Consequences to Breaking Space Laws

Ep. 671: The Consequences to Breaking Space Laws

Last week we talked about the laws that govern space exploration. This week the rubber hits the road. What are the consequences for actually breaking these rules? Are they really going to stop anyone?

Ep. 670: Governing Space – The Outer Space Treaty of 1967

Ep. 670: Governing Space – The Outer Space Treaty of 1967

The Universe was inaccessible for most of human history, but the first tentative steps to space in the 20th century made humanity realize that science fiction was becoming science reality. New rules would have to be written to govern how we used this limitless expanse. Today we’ll talk about the Outer Space Treaty of 1967.

Ep. 667: JWST First Science Results

Ep. 667: JWST First Science Results

Astronomers came together in January to present their newest research, and not surprisingly, the Winter AAS meeting was heavy on news from JWST. What were some of the new results that were announced?

Ep. 661: Looking Back on the Missions That Ended

Ep. 661: Looking Back on the Missions That Ended

It’s always sad to say goodbye, but when we send our robotic emissaries out into the cosmos, it’s just a matter of time before they shut down. Today we’re going to say goodbye to a few missions which have reached the end of their lives. But they were very good robots.

Ep. 659: Clear Skies, Bright Satellites

Ep. 659: Clear Skies, Bright Satellites

Light pollution is a big problem, and it’s only getting worse — not just near cities but everywhere thanks to increased satellite constellations. How bad is the problem, and how can we fix it?

Ep. 658: Space Exploration Horror Stories

Ep. 658: Space Exploration Horror Stories

We’re recording this episode on Halloween, so how could we resist but take advantage of this opportunity. Space is already terrifying enough, you know, with the vast endless emptiness, incomprehensible mysteries, and uncaring coldness. But here are some scary stories to spook it up a notch.

Ep. 655: 65 Years of Space: Sputnik 1 Anniversary

Ep. 655: 65 Years of Space: Sputnik 1 Anniversary

It’s been about 65 years since the Soviets launched the first orbital satellite into low Earth orbit: Sputnik 1. Now there are thousands of satellites in orbit, with tens of thousands on the way. Let’s look at the impact that Sputnik had on the history of spaceflight.

Ep. 652: The Rocket Race Toward Reusability

Ep. 652: The Rocket Race Toward Reusability

Last week we talked about how single-use rocketry has changed over time, and the role it still plays in launching payloads into orbit and beyond. Today, we’ll address the stainless steel elephant in the room and talk about the shift to reusability.

Ep. 651: Artemis and the Decline of Single Use Rockets

Ep. 651: Artemis and the Decline of Single Use Rockets

On the day that we’re recording this, NASA’s Space Launch System is about to blast off. But everyone is expecting it’ll be delayed to October. When it does launch, it’ll be the most powerful rocket on Earth. Well, until Starship blasts off. Are we about to see the end of single-use rockets and enter the era of reusable rocketry?

Ep. 650: First Light for JWST

Ep. 650: First Light for JWST

Well, this is it, we’re finally going to talk about the James Webb Space Telescope. After decades of development, delays and budget creep, the powerful infrared observatory is at its final home at the L2 Lagrange Point. Yesterday we saw the first scientific images from the telescope, and according to Pamela’s rules, we’re finally allowed to talk about it.

Ep. 646: Long Term Future in Space

Ep. 646: Long Term Future in Space

We always say that we’re living in golden age of space and astronomy, but it feels like things are just accelerating. What does the long-term future hold for our place in the Universe?

Ep. 645: The Future of the ISS

Ep. 645: The Future of the ISS

The International Space Station has been continuously inhabited for over 20 years now, serving as a peaceful collaboration between space-faring nations. But it’s a machine, and it’s getting old. In addition, the Russian invasion of Ukraine has made things complicated. What’s the future for the ISS?

Ep. 640: Survey Science: Newest Projects and Results

Ep. 640: Survey Science: Newest Projects and Results

There are general-purpose telescopes and missions that astronomers can use to study specific objects. And there are survey missions that look at the entire sky, which astronomers can use to answer questions about the Universe. We’ve talked about surveys in the past, but the landscape is changing fast so it’s time for an update.

Ep. 630: Things We Can Look Forward To

Ep. 630: Things We Can Look Forward To

In a rare moment of weakness, Pamela has decided she’s open to the possibility that a future exists. That missions, telescopes and spacecraft are going to be built and they’re going to do some science. Today we’ll talk about what we’re looking forward to before she changes her mind and ruins Fraser’s naive optimism for the future.

Ep. 629: The Cost of Delays

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

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

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. 625: End of the Year Review

Ep. 625: End of the Year Review
