SpaceX has launched yet another batch of Starlink satellites – a full complement of 60, the standard size for its current Falcon 9-based Starlink missions. This brings SpaceX's total to just around 1,000 in active on orbit, taking into account the handful that were experimental or have been de-orbited to date. This follows SpaceX's opening of orders for Starlink to anyone in a current or planned coverage zone.
Starlink is a global satellite-based data network powered by small, low-Earth orbit satellites. Historically, broadband satellites have been large, expensive spacecraft positioned much further out from Earth in a fixed orbit, providing service to a single coverage area. Because of their distance from Earth and the way they connect to base stations, coverage has been very high-latency and relatively inconsistent (which you'll recognize if you've ever tried to use Wifi on a flight, for instance). SpaceX's constellation-based approach sees the satellites positioned much closer to Earth, which improves latency, and also has the satellites orbiting Earth and handing off connections between one another, which in theory provides more consistent coverage – particularly as the size of the constellation grows.
Eventually, SpaceX intends to provide coverage globally from Starlink, with an emphasis on offering service to areas. where coverage has been weak due to ground infrastructure challenges in past. For now, however, coverage is limited, though SpaceX recently expanded its closed beta to an open one, with anyone able to sign up via the Starlink website after an address check, and place an order, including a deposit with the full amount for the hardware kit to be charged once it ships.
Starlink's hardware includes a small satellite receiver dish for installation by the customer at their service address. The service itself costs $99 per month, while the equipment is $499 (one-time fee). This does seem steep, but SpaceX CEO Elon Musk said on Twitter recently that the plan is to have the costs come down over time, once the significant initial investment is recouped. He also noted that the plan is still to spin off Starlink and have it IPO eventually, once the company "can predict cash flow reasonably well."
