摘要

Alph ewig was coordinating communications for SpseeX Dragon cargo flights to the I ntemational Space Station when he realized the growing commercial space industry would need its own data-relay network.As a mission operations engineer working in SpaceX's mission control room, Ewig was responsible for coordinati ng communications between the Dragon capsu'.e and SpaceX's mission operations center, NASA's mission operations center, the International Space Station, NASA's Tracking and Data Relay Satellites (TDRS) and multiple ground stations. When TDRS was available to piovide continuous communications links, SpaceX could monitor the spacecraft round-the-clock, delect problems and quickly resolve them. When SpaceX could not use TDRS because the constellation's time was claimed by other NASA missions, Ewig had to wait for the spacecraft to pass over one of about a dozen ground stations before he could send or retrieve data.
