Juno The Spacecraft Essay

946 words - 4 pages

There are many spacecrafts in our solar system that are observing planets, discovering new things, and even looking for signs of life. One of these spacecrafts, Juno, was sent into space on Friday, August 5th, 2011. Its main purpose is to travel to Jupiter and explore this giant gas planet a little more in depth. Despite the fact that it has been travelling for many years, it still has a little more than 2 years left till it reaches its destination. This is a long time travelling through the harsh surroundings of space. There are many factors that had to be considered while building Juno, such as the use of materials.
Materials is an important factor that is taken into consideration because ...view middle of the document...

Another major factor to be controled is how to protect the electronic instruments from radiation, since there are lots of radiation waves in space. The engineers of Juno solved this problem by designing a radiation vault which would shield Juno’s sensitive electronics from harmful radiation. This vault is built out of titanium. The titanium walls basically absorb the electrons and protons, and protect the spacecraft’s instruments and solid-state electronics. Titanium is a great material to use in spacecrafts because it is lightweight, strong, not dense, corrosion resistant and plentiful in nature. Though, the aluminum insulation also helps protect Juno from radiation by reflecting radiation off of its surface.
There are many limitations, though, as to what Juno can do, and where it can go. For example, Juno, which runs on solar energy, would not be able to journey far off into our solar system, or out of our solar system, because it would have nothing to fuel itself. This is because the sun’s solar rays will not be able to reach far out into the solar system, thus it will not function. Another limitation is that Juno will not be able to enter Jupiter’s atmosphere. This is due to the fact that Jupiter’s atmosphere is very dense and is composed of many harmful materials, such as methane, ammonia, oxygen, nitrogen, and many more.
There are also some implications during the building of spacecrafts, such as environmental and economical. One environmental implication is that, in order to obtain the titanium, it has to be mined. Now, mining is a long, hard process which causes pollution. This is bad because, since there would have to be mistakes that have been made, it would take more titanium to mine. There are also economic implications, along...
