• #82 Apollo-Soyuz at 50! It’s been a half century since this incredible project. The first international space mission.

    In 1975, an incredible and unlikely partnership resulted in the docking of a NASA Apollo capsule and a Soviet Soyuz spacecraft in Earth orbit. The cold war opponents worked together to overcome not only engineering challenges, but the rivalry and suspicion of the cold war.

    This cooperation led to the Shuttle-Mir program in the 90s and the present day International space station. They all began with the spirit of cooperation from Apollo-Soyuz.

  • #81 After centuries of Earth’s rotation slowing down, it’s now speeding up and making the days shorter. But you’d never notice.
    Jul 31 2025

    Send us a text

    Earth’s days had been getting longer since observations began. Every century, the length of the day would increase by about two milliseconds. Like… clockwork. In recent years, something strange has been happening, the days have started getting shorter as the rotation of the Earth has been speeding up. Even more strangely, we don’t really understand why.

  • #80 Plants on the Moon. An Australian team of biologists and engineers are really sending a mini greenhouse to the Moon.
    Jun 30 2025

    Send us a text

    An Australian team of botanists and engineers are working on a project that might make or break the future of long term, long distance space occupation. They're growing plants. Not that unusual, but they're trying to grow them on the Moon. Plants produce oxygen and they are food, essential elements of living away from Earth.

    Let's check out the plan to experiment with germinating seeds in shoebox sized 'lunariums' on the Moon within the next 12 months.

  • #79 Launched in 1972 for Venus, Kosmos 482 failed to escape Earth orbit — and finally returned in May 2025, after 53 years in space
    May 31 2025

    Send us a text

    Kosmos 482, was a Soviet spacecraft launched in 1972 on a mission to Venus, but a technical glitch meant it never made it past Earth orbit. Designed to withstand the hellish surface of Venus, its lander remained in space for over 50 years, but this relic of Cold War space exploration has finally returned, re-entering Earth’s atmosphere decades after its failed journey. Though the mission never reached Venus, Kosmos 482’s dramatic, delayed descent closes a half-century chapter in space history.

  • #78 The Andromeda Galaxy is a cosmic neighbour that’s going to collide with our Milky Way Galaxy. Should we panic?
    Apr 30 2025

    Send us a text

    No need to panic. Yet! We’ll be fine for the next 4 or 5 billion years, but Andromeda is heading our way. The Andromeda Galaxy was the first object to be identified as being outside our own galaxy, and it introduced us to extragalactic astronomy. And that’s not all. It can teach us more about dark matter and it could be home to billions of planets.

    It’s a very cool neighbour, but one day - it’s kinda going to move in!

  • #76 The Apollo program was the high point of the space age. From test flights, to lunar landings and the moon buggies
    Feb 28 2025

    Send us a text

    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.

  • #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
    Jan 31 2025

    Send us a text

    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.
