Summary Draft 2

 ATLAS V ROCKET LAUNCH SYSTEM STAGE 1


The article "Atlas 5 launch timeline for Starliner’s Orbital Flight Test" (2019), briefly introduces Atlas V, an expendable launch vehicle for payloads, and its launch sequence. The launch series consists of two stages and this summary aims to explain the functions and features which aid the first stage of launch.

 

According to NASA (n.d.), the Atlas V features a common core booster which is powered by a main engine called "RD-180", and several additional rocket boosters. The common core booster functions to propel the rocket. The RD-180 engine is further controlled by another feature, a guidance computer, during launch (Clark, 2019).

 

The function of the solid rocket boosters is to provide additional thrust at liftoff from its initial grounded position and an Atlas V can hold up to 5 additional boosters (ULA, n.d.). Afterwards, it will jettison and the rocket proceeds to the next stage of its launch sequence.

Descriptive Reflection

 Subject: Self Introduction   Dear Professor Blackstone I am writing this letter to properly introduce myself to you. My name is Muhammad Daniel bin Rosli, and I currently am enrolled as a first year in the Robotics Systems Engineering (RSE) course in Singapore Institute of Technology (SIT) and I am from your UCS1001 module. I graduated from Singapore Polytechnic with Diploma in Electrical and Electronic Engineering.   I had chosen to enroll in my current course in SIT due to my great interest in programming. During my years in polytechnic, I had barely touched about programming. That short moment however was enough to sway me, and I have chosen to pursue a career path revolving programming since then. The idea of writing code itself was honestly quite enticing. Strings of words that I write down are then executed to give me exactly what I asked for. I love logic and rationale, so it gives me satisfaction to just write code.   A weakness I believe I hav...

The Importance of communication skills for engineers

    "Developing excellent communication skills is absolutely essential to effective  leadership. The leader must be able to share knowledge and ideas to transmit a  sense of urgency and enthusiasm to others. If a leader can't get a message across  clearly and motivate others to act on it, then having a message doesn't even  matter."   Gilbert Amelio, former President and CEO of National Semiconductor Corp. As someone in charge, having amazing ideas in your head amounts to nothing if there is not a team member who understands how you express it.
