There's a strange gap between the orbits of Mars and Jupiter, a gap where Bode's law says we would expect the fifth planet to be. There's no planet there, but there's something else that's just as amazing, it's the asteroid belt. Let's take a look at the four main asteroids and see what makes up the other million identified objects.

1 #77 The stranded astronauts are finally home after 9 months in space. Let’s see how Suni Williams and Butch Wilmore got home 6:09
Their planned 8 day visit to the International Space Station was turned on its head when NASA announced their Boeing Starliner capsule was unsafe to use. What did Suni Williams and Butch Wilmore do for those 9 months? And we check out the plan that was put together to get them home safely.

1 #76 The Apollo program was the high point of the space age. From test flights, to lunar landings and the moon buggies 10:45
After everything learned through Mercury and Gemini culminated in the seventeen Apollo missions. The first ten were all testing and rehearsals, but the whole program, and a whole era was characterised by Apollo 11, the first time humans set foot on the moon. Along with the triumph, there was tragedy and a very near miss, and one of the most underrated aspects of NASA's space program - the lunar roving vehicles that let the astronauts explore more than seven kilometres from the Lunar Module. This really was one of the most remarkable endeavours of science, engineering and teamwork. Let's dive in.

1 #75 NASA's Project Gemini was a spectacular program that bridged the gap from Project Mercury to Apollo. Gemini developed the incredible technology and techniques needed for the lunar program 10:59
Nasa had accomplished spaceflight with Project Mercury but the gap to Apollo was still huge. How do you dock two spacecraft in flight and how do crews live in a tiny spacecraft for lunar length flights. These are just a couple of the questions that NASA needed to answer. Gemini was just the project to resolve all of these issues. It was a proving ground, for learning, testing and practicing the skills needed for lunar missions. Gemini wasn't the first program to accomplish spaceflight, and it didn't include the most well known achievements, but it was a formidable project in its own right. Let's check it out.

Back in the late 1950s, NASA was formed. Its first job was to put together a human crewed spaceflight program and put an astronaut into orbit - safely. This was Project Mercury. There were some uncrewed developmental flights and then six crewed flights between 1961 and 1963, this was an enormously significant step toward the Apollo moon landings just six years later. So who were the Mercury astronauts and what was the mission profile of these first six crewed spaceflights?

Project Mercury was NASA’s first attempt at human crewed space flight. It sent Alan Shepard into space, and John Glenn into orbit, among four other landmark flights over 5 years. By 1963 it was done, and NASA was ready to launch Gemini, its next project. But being such a groundbreaking project, in 1964 NASA paid tribute to Mercury with a four metre high stainless steel monument with a time capsule that would remain sealed beneath it until the year 2464, five centuries later. What was so significant about Mercury? And what’s inside this time capsule? We could wait another 440 years, or just listen!

When Yuri Gagarin blasted into orbit in 1961 to become the first human in space, he was already 14 years behind the first animals from Earth. The fruit flies that were flew to space in 1947 were just the first of many different animals in the decade and a half before Gagarin’s orbital flight that were used to test equipment and living things’ capacity to survive and work in weightlessness. There were primates, dogs, mice and rabbits that crewed orbital and suborbital test flights. And the animal parade didn’t end when humans launched themselves to space, frogs, fish, spiders, chimpanzees, a cat and of course guinea pigs all played a role in advancing the space program.

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.

1 #70 The Boeing Starliner capsule's first crewed test flight has left two astronauts stranded on the International Space Station. What went wrong, and how are they going to get home? 7:05
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.

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.

Around the 21st of June every year is the June solstice. We might know that it’s the longest or shortest day of the year – depending on which hemisphere you’re in, but why does that happen? And we know of the Tropic of Cancer and the Tropic of Capricorn, but how does the solstice define them? Same with the Arctic and Antarctic circles. Does it fall on the same date each year?

In 1978, NASA changed the rules around who could be selected as an astronaut. Civilian engineers, doctors and scientists could be selected to fly on the then brand new space shuttle. Meredith Bagby joins us to talk about this group, whose social backgrounds were as diverse as their professions. For the first time, the group included women and people of colour. There were triumphs with astronauts like Sally Ride and Greg Bluford, and tragedy when four of this talented group were lost in the Challenger disaster.

Caroline Herschel is probably best known as the sister of William Herschel, the person credited with the discovery of planet Uranus, but there's a lot more to her than this. Caroline was a great astronomer in her own right, having made numerous discoveries using telescopes she helped make herself. She was also an outstanding musician and was the first female professional astronomer in the world, and was recognised with the Gold Medal of the Royal Astronomical Society.
