# Astrophile
# Meaning
If you search for Astrophile you will come up with the following meaning:
A person who loves stars, astronomy
So if love watching sky, planets, stars or great admirer of work done by NASA, then you are an Astrphile.
# Motivation
Ever since I was always fascinated by stars, astronomic events but that much untill I first came to know about Voyager's Mission, an attempt to study the most distant planets of our solar system, in 2019. I was highly fascinated about how they are still in contact (as of 2021) after about 40 years of there services.
Thereafter I explored some later missions like New Horizon, Cassini, Hubble Space Telescope and others which deeply lighten my fire to understand and love more about astronomy.
# Education System
The most heart breaking thing that I feel about our current education system is the missing astronomy syllabus and the enthusiastic teachers. Astronomy is the most interesting subject which is generally fascinating to young students. This subject's application can be easily seen in real life by just waiting for sun to dusk.
I remember a quote from a great physicist:
Today our children are more busy with those grey color devices where the use of brain is considered illegal. Isn't its the best if our children could know more about missions, galaxies, pulsars, black hole? Don't know if that day would come or not but I am sure I wouldn't miss the journey
# The beginning
After i dwelt more into voyager i came to know that the current speed of Voyager 1 is about 27.2 Km/sec.
Can you just imagine how large is it?
It is covering 27 Km every tick of the clock. Such a huge velocity which would just take few seconds to reach anywhere in the world. Once I was imagining what feeling it would be to sit on this voyager with such enormous speed? But then I realise its a quite lonely journey with no mass surrounding, and its paving through the darkness of the space.
# Voyager 1 & 2
The twins were set off for a long never come back journey on 5 sept 1977 (Voyager 1) and its still 40+ years of active communication.
Fun Fact
Do you know it takes around 20 hrs for signal to reach from end to another ie from earth to voyager and vice versa. Its just huge time even though signal travels at light speed which is 3 lac Km/s.
The mission aim was to study the distant planets of our solar system ie Saturn, Uranus, Neptune. Its said that the planet position were the best at that time to reach these planets. Both the space craft successfully completed their mission and because of their performance the mission was extended beyond that to study outer solar system.
Some peculiar features of Voyager mission are:
# Gravity assist technique
Gravity assist or sling shot was the first ever technique used in real on voyagers to boost up their speed in their journey. As we all know we have a constraint on max speed that can be given to space craft, hence to cut out the travel time, voyagers were made to boost up their speed with the help of gravity assist of Jupiter. This caused the speed to multiply also leading to deviation in their path followed.
This is a very critical step, as slight mistake would cause space craft to either embed in the planet itself or is too far away to utilise gravity assist. Indeed what a great engineers mindset behind it. Hats Off!!!!
