Introduction

The selected “case study is Hubble Space Telescope System” Engineering, an astronomical observation that operates in orbit. It is mainly used to carry several instruments that produce photometric, imagining, astrometric and spectrographic data via parallel and pointed observing programs. What I saw interesting in this case study was how the system engineering concepts were used during the Hubble Space Telescope and made after the Hubble Space Telescope project. It was also interesting to learn about the size of the Hubble Space Telescope that was almost the size of a larger bus and had a weight approximated to 24,500 pounds. The Hubble Space Telescope has observed about 13.4 billion locations, which means it has witnessed the light that has existed in the World in the “13.4 billion years ago”. Many scientists have understood how planets and galaxies form by using a telescope.

The principles products and activities that were used to develop this project includes the following; –

1.
“LP1, Early and full participation by the customer/user throughout the program are essential to success”.

2.
“LP 2, The use of Pre-Program Trade Studies (Phased Studies or Phased Project Planning in NASA parlance at the time) to broadly explore technical concepts and alternatives is essential and provides for a healthy variety of inputs from a variety of contractors and government (NASA) centers.”

3.
“LP 3, A high degree of systems integration to assemble, test, deploy, and operate the system is essential to success and must be identified as a fundamental program resource need as part of the program baseline”.

4.
“LP 4, life cycle support planning and execution must be integral from day one, including concept and design phases”.

5.
“LP 5, “for complex programs, the number of players (government and contractor) demands that the program be structured to cope with high-risk factors in many management and technical areas simultaneously.”

The development process used in the Hubble Space Telescope process was established at the start of the HST Project as a link between the astronomy community and NASA. It has external input to the Hubble Space Telescope operations and the NASA decisions regarding commencing design, necessity, on-orbit operations, and maintenance. The STScI makes sure there is early and full participation by users and customers that will be important in the final success. In the Conceptual design and architecting phase, the Hubble Space Systems uses the pre-program trade studies to access more technical alternatives and concepts. The example I noted in the case study is a selection of primary mirror size, which was initially 3 meters. Still, after cost trade studies that found the primary mirror meters below 2.4, NASA deducted the mirror to 2.4 meters, which led to a reduction in the cost. The extent to which this development process reflected on my understanding of the system life cycle is that it has equipped me with knowledge on how planets and galaxies get formed. I note that galaxies consist of billion. This development has also earned skills on explosions that take place when huge stars are burning out.

The best practices that were missing in the early years after the Hubble Space Telescope was launched in 1990 was that the main mirror was improperly grounded, leading to the spherical aberration consisting of telescopes capabilities. In 1993, the optics were amended to their initial quality through the servicing mission.

The deployment of the Hubble Space Telescope system was achieved by payload configuration from the Hubble Space Systems that was stored in the “shuttle orbiter payload bay” by the use of active keel fitting and the latch retention assemblies. Some control interface power, connect and disconnect umbilical and complex electrical interfaces, and a set up was done in “remote operation from the Orbiter flight deck.” Closed-circuit TV and berthing aids were available. Hubble Space Telescope is customized for light during the launching pad at the end of “prelaunch testing.” All-important bus electrical, key shutters, and heater get powered in the process.

The Orbiter powered the bus from prelaunch via the deployment and was observed by a computer system known as Orbiter; this gave the crews grounds to identify any computerized failure that may arise in the internal bus power. The deployment complete set operation can be described effectively with the significant deployment event 19. Examples can be seen in “LP 3, A high degree of systems integration to assemble, test, deploy, and operate the system is essential to success and must be identified as a fundamental program resource need as part of the program baseline”. The lesson I have learned is HSP helps collect light from the comic object so that we can be in a position to understand our universe.

The Hubble Space Telescope System will still be maintained in space by the astronauts responsible for upgrading and replacing the system. The system’s future evolution will be managed and planned until 2030 to 2040, with one successor known as James Webb Space Telescope (JWST). An example is when the astronauts were involved in replacing equipment “housed in the equipment section in the orbital replacement units.”
