The Starlink initiative has notably increased its satellite constellation, with around 7,000 satellites currently in orbit around the Earth. This ambitious project seeks to deliver high-speed internet access on a global scale, with a particular focus on underserved and remote areas. Nevertheless, the swift launch of these satellites has ignited conversations regarding their visibility, tracking techniques, coverage zones, historical evolution, and the implications for astronomical research.
Tracking and Observing Starlink Satellites
The “Starlink satellite train” has become a captivating sight for skywatchers, offering a glimpse of the future of global internet coverage. This dazzling spectacle occurs shortly after SpaceX launches a new batch of its Starlink satellites — part of the megaconstellation that provides high-speed internet worldwide. On clear nights, you may spot these satellites as they streak across the sky, resembling a string of bright, evenly spaced lights.
At a certain moment, each satellite ascends into its operational orbit. For observers, it means that they separate from the line. Once they reach this orbit, they become much harder to distinguish in the sky. However, they can still be seen with optics or captured on cameras.
Starlink satellites can frequently be seen with the naked eye, particularly soon after their launch, where they manifest as a series of bright lights resembling a “train” traversing the night sky. To ascertain their visibility in your vicinity, specifically in Multan, Punjab, Pakistan, several resources are available to assist you:
1. FindStarlink: This platform offers forecasts regarding the visibility of Starlink satellites tailored to your specific location.
2. Starlink Coverage Tracker: This tool provides real-time updates on the positioning of Starlink satellites and their coverage zones.
3. ISS Detector App: Initially created for monitoring the International Space Station, this application has been updated to include functionalities for tracking Starlink satellites.
These resources leverage your geographical coordinates to deliver precise timings and paths, thereby increasing your likelihood of witnessing the satellites. It is recommended to consult these tools regularly, as visibility can fluctuate due to factors such as orbital changes and atmospheric conditions.
Starlink Coverage
Starlink aims to provide worldwide internet access, particularly targeting regions where connectivity has been inconsistent or lacking. The configuration of its satellite constellation guarantees that every location on the planet is served by several satellites, ensuring uninterrupted and dependable internet service.
Starlink is officially compatible with Apple devices, allowing you to connect to its services from anywhere using your phone. Starlink now offers a backpack-sized “Starlink Mini” dish that you can carry anywhere to extend your coverage.
That number exceeds Shotwell’s April estimate that the company could put around 1,600 satellites in low Earth orbit this year, with continuous global coverage possible after about 28 launches.
In the same month, the US Federal Communications Commission approved SpaceX’s plan to expand its high-speed broadband access to more people by placing some of its Starlink satellites at a lower orbit than previously planned. The approval followed a December award of $885 million in grant funding from the FCC to help Starlink provide greater broadband access across 35 states.
Currently, Starlink operates in various countries and has intentions for additional growth. Individuals can verify the availability of services in their locality by visiting Starlink’s official website, which features an interactive map illustrating existing coverage zones and future expansion plans.
History of Starlink
The idea for Starlink was conceived in the mid-2010s, with SpaceX’s objective being the establishment of a network of low Earth orbit satellites designed to deliver high-speed internet access on a global scale. The initial test satellites, known as Tintin A and B, were successfully launched in February 2018, representing the project’s first venture into space. Following the positive outcomes of these prototypes, the inaugural group of operational satellites was launched in May 2019.
The company’s goal was to provide high-speed internet access to people around the world, with a focus on rural and underserved areas.
Starlink is a satellite internet constellation operated by SpaceX, providing broadband services to over 60 countries and aiming for global mobile phone service after 2023.
Starlink consists of over 5,000 small satellites in low Earth orbit, they are used for communication via radio and laser links. The satellites are mass-produced and launched using reusable rockets, reducing the cost and enhancing deployment speed.
Impact on Astronomy
The widespread deployment of Starlink satellites has generated considerable apprehension within the astronomical community. Astronomers have noted that the luminosity of these satellites can disrupt both optical and radio observations, potentially jeopardizing scientific research. When illuminated by sunlight, the satellites can produce streaks in telescope images, obscuring the visibility of celestial bodies.
This problem is particularly acute during twilight hours when the satellites are most prominent.
The vast fleet of Starlink satellites is interfering with astronomical observations, a study published in Astronomy and Astrophysics has revealed.
When astrophysicists observed 68 of SpaceX’s satellites with the Low-Frequency Array (LOFAR) telescope in the northern Netherlands, they detected unintended electromagnetic radiation emanating from onboard electronics on the satellites.
SpaceX CEO Elon Musk has come under some flak for the Starlink project, particularly because he has claimed many times that the satellites will have zero impact on astronomical viewing.
However, SpaceX does intend to continue working on an effective solution to the problem. They even have plans to introduce a ‘sunshade’ that could potentially block out light from the sun entirely. Many are still a bit worried about the overall impact of such a massive satellite network, but with cooperation from SpaceX and further observations and testing from astronomers, they may prove not to be a problem at all.
In light of these issues, SpaceX has introduced several mitigation measures. A significant strategy involves modifying the operational altitudes of select satellites. By lowering some satellites to approximately 350 kilometers, the brightness detected in astronomical images has been reduced by nearly 60%. This adjustment is intended to decrease the reflectivity and visibility of the satellites, thereby lessening their impact on astronomical observations.
Furthermore, SpaceX has been working in collaboration with the scientific community to devise and implement additional strategies to tackle these challenges.
These initiatives include the design of satellites using less reflective materials and the exploration of operational tactics that could diminish their visibility during critical observation times.
Nevertheless, the vast number of satellites continues to pose persistent challenges. Projections indicate that by 2030, more than 100,000 satellites may occupy low Earth orbit, not only from Starlink but also from other proposed constellations.
This unprecedented surge raises concerns regarding space traffic management and the risk of collisions, which could produce space debris and further complicate astronomical observations. The international astronomical community remains committed to advocating for regulations and collaborative efforts to ensure that the expansion of satellite constellations does not irreparably impair our capacity to study the universe.

How Does Starlink Internet Work?
Starlink operates on a satellite internet service technology that has existed for decades. Instead of using cable technology, such as fiber optics to transmit internet data, a satellite system uses radio signals through the vacuum of space. Ground stations broadcast signals to satellites in orbits, which in turn relay the data back to the Starlink users on Earth. Each satellite in the Starlink constellation weighs 573 pounds and has a flat body. One SpaceX Falcon 9 rocket can fit up to 60 satellites.
As with any satellite telecommunications service, Starlink involves beaming internet data via radio signals through the vacuum of space. Ground stations then broadcast those signals to orbiting satellites, which relay the data back to Earth-side users.
But what differentiates Starlink is the sheer volume and short, geospatial proximity of its satellites.
The user terminal connects to the satellite network, which then transmits the signal to the ground station, where it is then connected to the internet backbone. This allows for stable high-speed communications in every corner of the Earth, as planned by Elon Musk.
This operational altitude greatly diminishes latency, resulting in a faster and more dependable internet experience.

Is Starlink affected by weather?
Starlink is indeed susceptible to various weather conditions, including heavy rain, snow, thunderstorms, and strong winds; however, its engineering is intended to reduce the impact of these disruptions.
Rain and Storms: Intense rainfall and thunderstorms can diminish the satellite signal, resulting in temporary slowdowns or brief service interruptions. Conversely, light rain typically has negligible effects. everyone must know that Starlink’s performance is seriously impacted by rain – yes, the thing that falls from the sky more often than we’d like to admit. Rain can cause signal attenuation – a fancy term for signal weakening. So, while SpaceX’s Starlink satellites can dish out high-speed internet in clear skies, a rainy day might make you yearn for the days of dial-up.
Snow and Ice: The Starlink dishes are equipped with a heating mechanism to prevent snow accumulation. Nevertheless, if snow builds up around the dish or obstructs its line of sight, connectivity may be compromised.Snow has mixed effects on Starlink’s performance. Falling snow can interfere with signals like rain does, but accumulated snow presents a bigger problem. If snow piles up on a satellite dish, it blocks the signal completely.
Strong Winds: While the dish is constructed to endure high wind speeds, extreme weather conditions could potentially cause misalignment. wind will not be an issue. The Starlink dish uses a phased array antenna. It can track satellites flying overhead without having to physically move. This also means that small movements, such as those caused by wind, will not interrupt the signal.
Clouds and Fog: The impact is minimal, as Starlink operates at high frequencies that can penetrate most cloud formations. Thick clouds and heavy rain can attenuate the radio signals traveling through the atmosphere. This could degrade your signal or, in rare circumstances, cause a temporary disconnection. Such severe storms are uncommon and brief, so your signal should return to normal when the worst of it passes.
Pros & Cons to Starlink?
Starlink does present certain disadvantages alongside its advantages. One significant issue is the high cost, which includes an initial equipment fee of $599 and monthly subscription rates ranging from $90 to $120, rendering it more expensive than conventional broadband services. Furthermore, connectivity can be compromised by adverse weather conditions, such as heavy rain or snow.
I guess you’re here because you’ve probably heard people raving about Starlink and you want to check out what the inside scoop is.
Should you go for it and try it out? Will you really be able to make it work? What are the risks of trying to use Starlink for your connectivity, will it be as reliable and as amazing as people proclaim or will it just be another disappointment?
The advantages of going in for a satellite-based internet are far too many not to go in for it, he said. Undersea cables, which are now being used for global internet connections, can be cut due to war or accidents, Yogarajan pointed out.
Starlink’s biggest advantage is its ability to serve rural and remote areas where traditional internet services fall short. If you live in a location where fibre or even cable internet isn’t available, Starlink could be a game-changer. Its global coverage provides fast and reliable internet, even in hard-to-reach areas.
The extensive number of satellites in orbit raises additional concerns regarding space debris and light pollution, which can negatively impact astronomical observations. Moreover, users may experience latency and variations in speed due to satellite positioning and network congestion. Other limitations include restricted availability in urban regions and elevated power consumption. Nevertheless, as the network continues to develop, it is anticipated that many of these challenges may be mitigated.
