    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.

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

    #76 The Apollo program was the high point of the space age. From test flights, to lunar landings and the moon buggies
    2025/02/28

    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.

    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?

  • #73 NASA’s Project Mercury Monument has turned 60! It’s a tribute to America's first attempt at human space flight. The monument has a time capsule that is scheduled to stay sealed for 500 years! Let’s check out what's inside.

    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!

  • #72 The space pioneers from Earth weren’t humans, what? That’s right, long before humans launched into space, there were a whole team of dogs, monkeys, chimps, insects and more, who rode rockets to space. All in the name of research.

    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.

    One very famous space animal has her own statue.

    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.

    #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?
    2024/08/31

    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?
