With its Atlas V and Delta IV rockets, ULA sends payloads into space that cover a wide range of topics, from deep space and interplanetary exploration missions that expand our understanding of the cosmos to weather, telecommunications, and national security satellites that safeguard and enhance life on Earth.
In our life, launch vehicles, often known as rockets, are essential. Satellites are sent into space by rockets, where they can start their vital mission. Among the many things we would be unable to do without rockets are usage of cell phones, viewing of many of our favorite TV shows, weather forecasting, GPS navigation, and solar system exploration.
This is how it operates: the rocket's potent main engine ignites and generates thrust upon liftoff. The rocket's payload accelerates as it moves away from the launch pad due to thrust. Typically, a rocket can lift more than 6,000 pounds at speeds exceeding 22,000 miles per hour thanks to its more than one million pounds of power. This is the same as the energy produced by thirteen Hoover Dams, eight horses' worth of weight, and fifteen times the speed of a bullet!
The launch vehicle delivers its payload to the intended orbit or on the specified trajectory after exiting Earth's atmosphere. When positioned correctly, the payload can start doing the tasks that improve our quality of life, increase our enjoyment, and aid in our education.
The Rocket Terminology
Jettison: to dispose of, to throw away
Liftoff is the moment a rocket takes off and starts to fly.
A satellite's or spacecraft's orbit is its route as it circles the planet Earth or another planet.
satellite: a spacecraft launched into Earth's or another planet's orbit
A spacecraft is a vehicle designed to travel across space.
Thrust is the force that a rocket engine produces that moves forward.
A moving object's trajectory is the path it takes through space.
