SpaceX explains how its internet satellites will survive in orbit



Each flat screen has multiple high-throughput antennas and a single solar array. Each satellite weighs only 227 kg, so it's both light and lean. Despite their small size, they have a number of operational features. First, Hall engines driven by krypton to adjust their position in orbit and maintain the intended altitude. Each satellite also comes with a Startracker navigation system that SpaceX can use to precisely align them.

Even in the lower orbit of the satellites, a lot of garbage floats around, making a collision a risk. Satellites can track debris in orbit and avoid it autonomously. In addition, 95 percent of all components of this design will burn at the end of the lifecycle of any satellite in the Earth's atmosphere – SpaceX is committed to achieving 100 percent of that in the future.

The launch window is currently scheduled for Wednesday, May 15, 10:30 pm ET / 7:30 pm (PT), however, in the event that last minute changes need to be made (a delayed start would not be required) a backup window available exceptionally for SpaceX). These first 60 satellites mark the beginning of Starlink's global Internet connection, which will eventually cover approximately 12,000 satellites if the network is complete by the mid-2020s. Watch the start live here.
