Hello all, welcome to yet another blog where I’ll be explaining rocket science and breaking the concepts into simple principles of physics. Today we shall get to know how SpaceX’s Falcon9 booster-stage lands with precision. But why only Falcon9?? I mean orbital rockets have been in existence since the 1950s’ but there had been no vertically landing rockets until 2015. It may seem surprising but the concept of vertical landings is pretty old. So, why we didn’t see any of the vertical landing rockets? Hold on, this article will solve all your doubts, so without much further ado let’s dive in he ..read more

    “The most bizarre, the most absurd, the most crazy prediction that quantum mechanics makes is, Entanglement.” ~ Walter Lewin, 2014  Everyone of us taking some interest in quantum mechanics, must have heard of this perplexive phenomenon, “Entanglement”. What is it simply? Does it really happen? How does it help? Let’s dive right in to find out! Do checkout our previous introductory article on quantum entanglement for more learning! What is Entanglement?   Entanglement is a theoretical prediction that comes from the equation of quantum mechanics! Any two particles can ..read more

A conclusion is simply the place where you get tired of thinking  ~ Dan Chaon, Stay Awake Hello all, Happy Basant Panchami, and welcome to the final blog of this series, where I will try to answer some frequently asked questions about the mighty Saturn-V and the moon missions in general. The previous 4 articles were about the history, engineering, engines, and missions of the rocket (highly recommended going through them, please give them a read). I tried to cover the rocket from every possible angle in all four with a generalized approach. But today I shall be concluding this series, bu ..read more

That's one small step for man. One giant leap for mankind. ~ Neil Armstrong Hello readers and welcome back, it has been quite a journey exploring the Saturn-V. In our path, we came across 3 major milestones; 1st one was the history of the development of the rocket, then we got an overview of the whole machine, then we got to know the propulsion system or the engines of the rocket, if you haven’t read them, you are missing out on a tonne, links are provided go and check it out first. Hope you are back after reading all of them. So, welcome back again!! Today, we are going to see th ..read more

Inside the F-1 engine Hey again everybody, in our journey about studying the mighty Saturn-V, till now we saw the history of its development and got a basic overview of the rocket if you haven’t read them yet, I highly recommend going through them now as the previous blogs play a vital role in setting up the context of this blog. But what is this blog really about? As is evident from the topic mentioned above, we’ll be learning about the engines today. A vehicle can only be called a rocket if it has a rocket engine, rocket engines are reaction engines meaning that spew out fluid that ..read more

Happy Makar Sankranti/Pongal and thank you, readers, for the tremendous love and support in my previous article on the History of Saturn-V. If you haven’t read that yet, I would highly recommend giving it a read, this will help you to get the context of this article (click here to read it). In this article, I will be giving you the machine overview and try to answer the question, what this Saturn-V actually is. So, without much further ado, let’s get to the point. The Machine Overview: Getting the Rough Idea Saturn-V is a 3-stage vehicle, with each stage namely; S-IC first stage, S-II sec ..read more

The mighty Saturn-V delivered humans to the moon in just about 3 days. Standing at a whopping height of 110m, weighing nearly 3 million kilograms on the launch pad, and having a payload capacity of 140,000kg to the low earth orbit, this beast continues to be the most powerful rocket that mankind has ever built. But, why did the rocket only function for a short span of only 6 years (from 1967 to 1973) despite its exceptionally successful track record? How come a machine from the late 1960s stands unbeaten to this date? Answers to these questions (and many others) can ..read more

First of all, I wish all my beloved readers a very happy and prosperous new year 2022. I wish in this new year, we all can learn many new things and can apply those for the betterment of mankind. Before reading this article, I will highly recommend you to read the part-1 article in this series of Insane engineering of SpaceX’s Merlin Engine for better understanding. In this article, I will be introducing you to the basic concept of Turbopumps used in cryogenic engines. In later articles, we can use this knowledge for understanding Merlin’s design and functionality. So, let’s start… Now you ha ..read more

In today’s aerospace world, SpaceX needs no introduction. Being the largest private space technological company, SpaceX proved everyone wrong. But, to make this happen in the first place, they need a solid and reliable engine for their rocket’s and here they introduced their Merlin Engines. Known for their sheer power and reliability along with the reusable nature of the rockets, the SpaceX’s brought the launching cost dramatically lower than previous generations of rockets. Elon Musk - Founder, CEO and chief engineer of SpaceX To introduce you to the insane engineering they used for ..read more

International Space Station – an iconic satellite-laboratory orbiting our earth with a speed of about 7.66 km/sec, already inspired a whole new generation of future space scientists to dream big. Although, it was not the first space station introduced to the world. Both USA’s Skylab and Soviet’s Mir, inspired to create ISS. But this time, India also wants to join the elite league. As already, India is preparing for its first ever human space flight, ISRO’s chairman confirmed about Indian Space Station. It will be undertaken after the success of Gaganyaan mission that is, India’s first human ..read more
