Need your input

Hello there, This is a survey for my UX design project , where I need to design an website for ordering custom printed T shirts. To begin the process I need to conduct interviews about the project, If you are willing to be a part of my UX design journey and interested to share your thoughts, Kindly will the form to share thoughts, Your input means a lot. And share with the people who are interested to share their thoughts. If you are available please fill the form. I guarantee it will be fun activity,  Link to form:    https://forms.gle/potVXeUByvUUeKph7

Starlink mission

Why starlink?
          The SpaceX , founder Elon Musk introduce this mission Starlink.The aim of this mission is to provide continues internet globally with low letancy at speed but how?

How starlink works?
          Now you are reading this blog through your mobile or PC which is connected to internet,this internet you are getting is through cable providers or satellite communication.But cables are much cheaper and faster than satellite communication then why Elon Musk plans satellite connection.

When you use the internet through satellite communication,it produce 0.5 second letancy because these satellites are orbit around Earth at 22,000 to 35,000 km from the Earth surface and these are called as geostationary satellite

How Elon Musk plans?
           To reduce the latency mentioned above,the satellites will place in low Earth orbit because at Geostationary orbit it is difficult to connect the signals from satellite because it moves to some other place and the connection would be lose.

To avoid this problem Elon Musk planed to place the satellites as in constellation at low Earth orbit,it results to place more satellites to cover the Earth globally,and it requires nearly 12,000 satellites

By constellation,if an satellite in your view moves an another satellite will cover you and you will have a connection throughout,and there will be no latency,
this was not the first satellite constellation
The GPS you are using is by an constellation of satellites at Geostationary orbit.

Launches:

            Elon Musk is planned to launch nearly 12,000 satellites may be will increase up to 42,000 satellites by this time over 302 satellites were launched into the low Earth orbit ~(340 km - 1350 km), they launch 60 satellites per launch the with Falcon 9 rocket.By 2021,they planned to operate internet connection globally.

           This was not the new idea in 1990s the company called teledesic planned this constellation internet but they give up because at that time the cost is too expensive to launch

One web,Blue orgin(Amazon),telesat all these companies doing the same but SpaceX leads these companies because they have their own rockets,satellite,boosters.
