Have you ever think of accessing internet and ordering pizza while you are somewhere in the middle of amazon forest, a BIG YES ! soon it will happen through Space X starlink mission. Starlink is a satellite constellation being constructed by Space X to provide internet access. The constellation will consist of thousands of mass-produced small satellites in low Earth orbit (LEO), working in combination with ground transceivers. SpaceX also plans to sell some of the satellites for military, scientific, or exploratory purposes. The SpaceX satellite development facility in Redmond, Washington houses the Starlink research, development, manufacturing, and on-orbit control operations. The total cost of the decade-long project to design, build, and deploy the constellation was estimated by SpaceX in May 2018 to be about US$10 billion.
The first phase of this project was started back in 2015 with the first two prototype test-flight satellites launched in February 2018. Its second phase and its first large deployment of constellation satellite was conducted in May 2019 when the first 60 operational satellites were launched.
This company is aiming to launch 1584 satellites which weigh about 260 kg each. This will expected to come to service globally on by late 2021 and 2022. Space X will launch it beta version of this service in U.S and Canada in august 2020.
But launching large number of satellite into orbit leads to increase in space junk and space debris. These starlink satellite will orbit at the distance of 600 km from the earth surface, later it may lowered into 550 km or below. This will also affect the astronomical observation through telescope in earth which will receive the light reflected by these satellites. On Starlink 2, one of the satellites has an experimental coating to make it less reflective, and thus impact ground-based astronomical observations less. A June 2020 launch included one satellite with an experimental sunshade.
Space x will launch 58 more new starlink satellites to join its ever-growing broadband internet megaconstellation in orbit Saturday,June 13 2020. As of now space x (June 4) launched 482 starlink satellites. they plan to launch 60 more per Falcon 9 flight, with launches as often as every two weeks in 2020. In total, nearly 12,000 satellites are planned to be deployed, with a possible later extension to 42,000. The initial 12,000 satellites are planned to orbit in three orbital shells:
First: approx. 1,584 in a 550 kilometres (340 mi) altitude shell, then
Second: approx. 2,825 Ku-band and Ka-band spectrum satellites at 1,110 km (690 mi), and
Third: approx. 7,500 V-band satellites at 340 kilometres (210 mi).
but for launching such large amount of satellite it cost a lot, to cut down the cost of launches space x recovered their old spacecraft boosters. Currently the company has successfully recovered 53 first stage boosters and GO Ms. the Falcon 9 has proven that the same booster can launch and land five times,
SpaceX CEO and founder Elon Musk has previously stated that the company will need at least 400 Starlink satellites in orbit to offer "minor" broadband coverage, and at least 800 to provide "moderate" coverage. With this launch, they are more than halfway to that moderate coverage goal.
The main objective of this mission is to provide the users around the world with constant, high-speed internet access. The company plans to achieve that by launching a massive constellation of broadband internet satellites.

Users on the ground would then operate a small terminal no bigger than a laptop to gain internet access.
