Summary

The satellite identified by NORAD CAT ID 56335 and OBJECT ID 2023-058U is a Starlink satellite launched on April 27, 2023, from Vandenberg Space Force Base (AFWTR), SLC4E launch pad using the Falcon 9 launch vehicle. It measures 0.2 meters in length with a diameter of 2.8 meters and a span of 9 meters. The satellite has a dry mass of 260 kilograms and was launched at a mass of 300 kilograms. Equipped with a Ku/Ka-band payload and an optical inter-satellite link, it uses Krypton ion thrusters as its motor and solar arrays along with batteries for power. Its shape is described as "Box + pan" and it serves the purpose of communication as part of the Starlink Group 3-5-19 constellation managed by SpaceX (SPXS).

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.
