Summary
STARLINK-1635, also known as Starlink 1635, is a communication satellite belonging to SpaceX's Starlink constellation. It was launched on August 18, 2020, from the Cape Canaveral Air Force Station using a Falcon 9 launch vehicle. The spacecraft measures 0.2 meters in length and has a diameter of 2.8 meters with a span of 9 meters when its solar arrays are deployed. At launch, it had a mass of 260 kg and a dry mass of 248 kg. It is equipped with Ku/Ka-band payload equipment and optical inter-satellite links for communication purposes. The satellite uses krypton ion thrusters for propulsion and relies on solar arrays and batteries for power.
Starlink is a satellite constellation developed by SpaceX with the aim of providing global broadband internet coverage. Thousands of small satellites are deployed in low Earth orbit (LEO), enabling high-speed internet access even in remote areas. However, the rapid increase in satellites raises concerns about space debris and the potential for collisions, which can lead to further debris creation and endanger other spacecraft. Additionally, the sheer number of Starlink satellites can affect astronomical observations by increasing light pollution. Proper deorbiting plans and international coordination are essential to mitigate these challenges and ensure long-term sustainability in space.
