This thruster is used for both ensuring the correct orbital position, as well as for orbit raising and orbit lowering. While the specific impulse (ISP) of krypton is significantly lower than xenon’s, it is far cheaper, which further decreases the satellite’s manufacturing cost.Įach Starlink satellite is equipped with the first Hall-effect krypton-powered ion thruster. To further cut costs, Starlink’s propulsion system, an ion thruster, uses krypton as fuel, instead of xenon. To decrease costs, each satellite has a single solar panel, which simplifies the manufacturing process. The Starlink satellites are also equipped with an autonomous collision avoidance system, which utilizes the US Department of Defense (DOD) debris tracking database to autonomously avoid collisions with other spacecraft and space junk. This reduces the number of ground stations needed, allowing coverage of the entire Earth’s surface, including the poles. This allows each satellite to communicate directly with other satellites, not having to go through ground stations. The satellites also include a star tracker, which provides the satellite with attitude data, ensuring precision in broadband communication.Įach Starlink v1.5 satellite is also equipped with an inter-satellite laser communication system. Each Starlink satellite is equipped with four phased array antennas, for high bandwidth and low-latency communication, and two parabolic antennas. This is near the recoverable payload capacity of the Falcon 9 to LEO, around 16 tonnes.Īs small as each Starlink satellite is, each one is packed with high-tech communication and cost-saving technology. Due to this flat design, SpaceX is able to fit up to 60 Starlink satellites and the payload dispenser into the second stage, while still being able to recover the first stage. SpaceX developed a flat-panel design, allowing them to fit as many satellites as possible into the Falcon 9’s 5.2-meter wide payload fairing.

This profit will largely finance SpaceX’s ambitious Starship program, as well as Mars Base Alpha.Ī stack of 60 Starlink v1.0 satellites prior to be encapsulated into Falcon 9’s payload fairing. Once Starlink generations 1 and 2 are complete, the venture is expected to profit $30-50 billion annually. After 28 launches SpaceX achieved near-global coverage, but version 1 of the constellation will not be complete until all five shells are filled. Starlink is currently available in certain regions, allowing anyone in approved regions to order or preorder. The low-Earth orbit constellation delivers fast, low-latency internet service to locations where ground-based internet is unreliable, unavailable, or expensive. The first phase of the constellation consists of five orbital shells. Starlink is SpaceX’s internet communication satellite constellation. Starlink Group 5-5 marked the fifth launch to this Starlink generation 2 shell this is not the same shell 2 as Starlink generation 1, despite being gen 1 satellites. Starlink Group 5-5 marked the 76th operational Starlink mission, boosting the total number of Starlink satellites launched to 4,161, of which ~3,859 are still in orbit around the Earth. The Falcon 9 lifted off from Space Launch Complex 40 (SLC-40), at the Cape Canaveral Space Force Station, in Florida, United States.
