Q&A with Elon Musk, SpaceX’s founder and CEO

The mission will send the ViaSat-3 F3 satellite to a geosynchronous transfer orbit. Liftoff from Launch Complex 39A at NASA’s Kennedy Space Center is scheduled for 10:13 a.m. EDT (1413 UTC), at the opening of an 85-minute window.

The Federal Communications Commission has granted a request by SpaceX to begin launching spacecraft for the company’s Starlink broadband network to a lower orbit than originally planned, overruling protests by competitors and clearing a major regulatory hurdle before the launch of the first batch of Internet satellites from Cape Canaveral in May.

A commercial supply ship owned and operated by SpaceX arrived at the International Space Station on Saturday, delivering a pair of NASA experiments to demonstrate satellite refueling techniques and monitor changes in Earth’s forests, along with a special holiday menu of turkey, candied yams, cranberry sauce and shortbread cookies.
