One of humanity’s greatest achievements, the International Space Station is a $150 billion science laboratory hurtling around Earth at 17,000mph, its thin metal walls shielding astronauts from the most hostile environment humans have ever endured. Microgravity, the vacuum of space, extremes of temperature, micrometeorites - life here is perilous. To mark 25 years of continuous habitation onboard, Space Station We Have a Problem reveals how astronauts are only a technical glitch or software error away from disaster. From malfunctioning spacesuits and docking disasters, critical leaks and even the entire space station backflipping out of control, this is life and death played out in low earth orbit, coupled with the bravery and brilliance that each time, saves the day.

During a bizarre chapter of WWII, Nazi propaganda minister Joseph Goebbels decided to make a movie based on the sinking of the Titanic. This epic film was so large in scale that the Nazis were forced to divert men, material and ships from the war effort in order to complete it. Titanic was filmed aboard cruise ship SS Cap Arcona in the Baltic Sea. The movie’s director Herbert Selpin was arrested by the Gestapo over comments he made about the ship’s crew and he was questioned by Goebbels. Selpin was found dead the next day in his cell. The Gestapo’s verdict was suicide. Titanic never received the impressive premiere that Goebbels intended, being first shown in Nazi-occupied Paris in 1943. We reveal this little known but fascinating story by looking at the making of the film, as well as the fate of the German ship Cap Arcona.
