Modern rocketry is a pinnacle of engineering. It requires the right balance of multiple systems, and a deep knowledge of scientific principles such as fluid dynamics, aerodynamics, and chemistry. But a huge part of the brute force science done in rocketry has been ‘try and fail.’ Countless rockets have exploded in tests dating back to the cold war, and even though they are much less frequent today, there is still value in learning from explosive and expensive mistakes. Here is a compilation of rocket failures and testing from the last 70 years. ….because sometimes you have a day where you...
One of my first books on Astronomy was about the planets. It had a collection of pictures from the first missions to each of the worlds in our solar system. Seeing those photos, the planets felt so alien, so different, and the perspective was like something out a 1950s science fiction comic. But now, with modern advancements in imaging technology and rocketry, we can send heavier instruments to distant worlds, and see them in high definition. It changes the perspective and makes the world seem more familiar than alien, more livable and real. Take a look at the first picture...
As the capsule separates from the first stage rocket, the second stage booster takes over and sends Dragon into orbit around the Earth to rendezvous with it’s target a few hours from now. At this point the mission is a complete success from NASA’s perspective, but to Elon Musk and the rest of the SpaceX team, the real challenge is just beginning. They have to land that first stage rocket on a 300 x 170 foot barge in the vast ocean, or risk losing millions of dollars in their investment. Here’s how it went. Okay not so well, but arguably...
