Summary
The Starlink-2547 satellite, also known as 2021-036L, was launched on April 29, 2021, from Cape Canaveral Air Force Station's Launch Complex 40 aboard a Falcon 9 launch vehicle. It is part of SpaceX's Starlink constellation and serves communication purposes. The satellite measures 0.2 meters in length with a diameter of 2.8 meters and spans approximately 9 meters when fully deployed, featuring solar arrays for power generation along with batteries. Its dry mass is 248 kilograms, and it weighed 260 kilograms at launch. Equipped with Ku/Ka-band payload capabilities (applied to all units) and optical inter-satellite links (found in some prototypes), the satellite uses Krypton ion thrusters for propulsion and has a box-shaped body with a pan configuration. The manufacturer is SpaceX, which also owns the satellite.
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.

GPS III SV10 | The Last of Its Kind, and the First of What Comes Next
On April 21, 2026, the tenth and final GPS Block III satellite reached medium Earth orbit aboard a SpaceX Falcon 9. Named for Hedy Lamarr, the actress whose 1942 frequency-hopping patent underpins modern GPS, SV10 closes a procurement that took eight years to deliver hardware and opens the optical-crosslink era that will define the constellation's next decade.
