Why rockets don't fly straight up?

The Science Behind Rockets: Why They Don't Just Fly Straight Up


• Rockets, the vehicles that take humanity beyond Earth's atmosphere and into space, take a path that may appear contradictory to the untrained eye. They bend towards the horizon rather than shooting straight up. 

• This apparent diversion from vertical rise is not a defect in the design, but rather a carefully calculated strategy based on the difficult physics of space travel. We'll look at the science behind why rockets don't just fly straight up in this blog post.

• The Vertical ascension: 

Rockets begin their trip with an explosive vertical ascension. This phase enables them to quickly escape the Earth's dense layers of atmosphere, minimizing aerodynamic drag and the energy necessary to pierce through the air.

• The Gravity Turn:


When a rocket reaches a critical altitude, it begins the critical gravity turn. This controlled rotation shifts the rocket's orientation away from the vertical axis and toward the horizontal. The goal of this maneuver is twofold: to take advantage of the Earth's spinning speed and to reduce air resistance.

• Efficient Energy Use: 


Reaching orbit requires more than just reaching a given height; it also requires reaching a certain velocity. To balance the gravitational force and stay in orbit, rockets must fly sideways at incredible speeds. Rockets efficiently use their energy by changing from a vertical to a horizontal trajectory in order to achieve the required orbital velocity of around 28,000 kilometers per hour (17,500 miles per hour).

• Understanding Orbital Mechanics: 


Understanding orbital mechanics is critical in understanding the curved trajectory of rockets. Getting into orbit requires a delicate balance of gravitational forces and forward propulsion of the rocket. The gravity turn keeps the rocket moving horizontally, allowing it to enter and maintain orbit around the Earth or other celestial bodies.

• Maximizing Efficiency: 



Rockets' seemingly paradoxical journey is a tribute to the efficiency of energy and resources. Rockets minimize fuel consumption and increase efficiency in reaching the needed orbital speed by following a trajectory that mixes vertical and horizontal motion.

Gaganyaan Mission: India’s First Step to Human Spaceflight

Image
  Indian's journey in space exploration  • India has made amazing advances in space, from Mars exploration to lunar landings. Now, the country is set to take a huge step forward with the Gaganyaan mission, its first human spaceflight program.  • This historic endeavor will make India the fourth country to launch humans into space, after the United States, Russia, and China. What is the Gaganyaan mission?  Image Courtesy: ISRO, Wikipedia • The Gaganyaan mission, led by the Indian Space Research Organisation (ISRO), aims to send Indian astronauts (Vyomanauts) into space. The mission will deploy 2-3 humans in Low Earth Orbit (LEO), approximately 400 kilometers above Earth, for 5-7 days.  Mission Objectives   Image Courtesy: ISRO, Wikipedia • Send humans into space and return them safely. Create advanced technologies, such as life support systems and safe re-entry methods. Prepare India for future space missions, such as interplanetary exploration. Key Componen...

Extending Human Ability: The Fascinating World of the Third Thumb

Image
The third Thumb: • Designer Dani Clode has unveiled the Third Thumb, a 3D-printed thumb extender that has the potential to redefine the limits of human ability and enhancement. • The Third Thumb is a one-of-a-kind device that the user controls with his or her toes. This enables seamless interaction with the human hand, resulting in an intuitive and natural extension of the body.  • This project is more than simply a tool; it is an experience and research catalyst that calls into question our knowledge of prosthetics and augmentation. It makes us reevaluate what it means to be able-bodied, emphasizing the original meaning of the word " prosthesis " - not just to replace, but to add and extend. • The Third Thumb is currently being developed for neuroscientific research in partnership with the Plasticity Lab at University College London and Cambridge University.  • This study delves deeply into the mysteries of neuroplasticity, investigating how our brains can adapt to manage a...

The invention of time: Why do clock runs clockwise?

Image
• Time is a natural phenomenon, but the methods we use to measure and track it are human inventions. Humans invented timekeeping devices for a variety of reasons, including: • To plan and coordinate activities : It was difficult to coordinate operations that took place over long spans of time before the development of clocks and calendars. Farmers, for example, had to know when to grow and harvest crops, and merchants had to know when to send commodities. • To control religious rituals : Many religions do rituals at specified times of day or year. Muslims, for example, pray five times a day, while Christians celebrate Easter on the first Sunday following the first full moon after the spring equinox. • To keep track of the passage of time :  Humans have always been fascinated by the passage of time, and timepieces enable us to quantify and track how long things take. This can be useful for a variety of purposes, including event planning, appointment scheduling, and progress tracking...
