Earth has a new moon! well, for about 8 weeks anyway. Asteroid 2024 PT5 has been captured by Earth’s gravity and will be in orbit until late November 2024. This is really unusual and there have only been a few confirmed mini moons in the past. Our new temporary neighbour is only about 11 metres across and won’t be visible to anyone who doesn’t have a professional large-scale telescope, but we’ll know it’s there! and although it will only stay for about 2 months, 2024 PT5 will be back again in 2055.

Boeing’s Starliner space capsule blasted off for its first crewed test flight in early June. Great news right? Turns out, no. After arriving at the International Space Station, some technical problems meant that it couldn’t be used to take its crew of Barry ‘Butch’ Wilmore and Suni Williams back to Earth. The two astronauts were left with no way to get home.

The two capsules already docked at the space station couldn’t be used, so the astronauts were stranded.

Let’s find out what happened to Starliner, why couldn’t the other capsules be used, and how are the Starliner crew going to get home?

NASA's Curiosity rover touched down on Mars in August 2012, and it's been exploring the Red Planet all that time. There have been some amazing discoveries and it's travelled over 30km but it has just made the most scientifically significant discovery of its 12 year career, and did it simply by running over a rock! One of Curiosity's wheels crushed a rock. It had looked just like any other orange martian rock, but when it shattered under Curiosity's wheels, it revealed breathtaking yellowish green crystals inside, that turned out to pure sulphur. Unheard of on the Red Planet. Let's check it out!

As I write this, just a couple of days have passed since the Chang'e 6 sample return capsule touched down with its historic payload. The first sample of rock and soil from the far side of the moon touched down on Earth. This has the potential to unlock some of the secrets from the side of the moon that we never see from Earth, why is the lunar crust thicker? Why are there fewer 'seas' on the far side? And what lies beneath the lunar crust?
All of this against the background of a surface operation out of direct communication from Earth. Incredible!

In September 2023, Greg Brennecka stopped by to preview the return to Earth of the OSIRI-REx asteroid Bennu sample return capsule. The sample landed safely and the mission scientists like Greg Brennecka have started their analysis. Some of our toughest questions are being answered by the data already. How old is Bennu? Is there organic material? Where was the asteroid formed? Is Bennu different from what we expected?
But hasn't been all smooth sailing. The mission team had to go into full innovation mode to overcome some early difficulties.
And we've only just begun!
Listen in to this fascinating chat with Greg.

Titan. The largest moon in the Saturnian system has been a candidate as a habitable world ever since NASA’s Cassini mission sent back the first radar images of its surface in 2004. Astrobiologist Dr. Catherine Neish of Western University in Canada has spent years studying Titan, and has just published a study on the habitability of Titan. Catherine joins us to step through the findings, what is needed for life? Is there enough of it on Titan? And does it all come together?

Space and cosmology throws up some strange effects sometimes, none stranger than spaghettification. Stephen Hawking coined the term for the stretching out that happens when you get close to a black hole. Let's take a look at what it really is, how it works, and if we should have anything to fear from spaghettification...

Houston-based aerospace company Intuitive Machines produced the first private mission to land on the moon. The Odysseus lander is just 300 km from the lunar south pole, investigating water ice and demonstrating the capabilities of NASA’s Commercial Lunar Payload Services program (CLPS).

But space is difficult and not many projects go perfectly first time. Is Odysseus ok? Let’s find out!
