Updates from Saturday's event below: When is the SpaceX launch tonight? The first opportunity to launch the Starlink 6-18 mission is at 11:38 p.m. EDT Saturday night, with more backup opportunities during a nearly four-hour launch window that extends until just after midnight. Should teams need it, SpaceX has four backup opportunities available on Sunday beginning at 8:41 p.m. EDT. What is the weather outlook for the next SpaceX launch: Weather conditions for the Starlink 6-18 mission, according to the Space Force's Space Launch Delta 45, are expected to be excellent. Forecasters with the Space Force's 45th Weather Squadron on Friday predicted a 95% chance of "go" weather conditions around the spaceport for Saturday's launch window. The only concern is a slight chance of lingering clouds from a coastal tropical system making its way out of the area over the weekend. "By Saturday evening, this system will be over North Carolina, leaving mostly dry conditions and northeasterly winds at the Spaceport," forecasters said in Friday's report. Recovery conditions for the booster landing attempt were listed as "low risk." Here's everything you need to know about Starlink 6-18: Cape Canaveral Space Force Station's Launch Complex 40 will host. The payload is the company's next batch of Starlink internet-beaming satellites. The 230-foot Falcon 9 rocket will follow a southeasterly trajectory threading between Florida and the Bahamas. If it launches on time, it will mark the Space Coast's 51st launch this year. No local sonic booms with this mission. The 130-foot first-stage booster will target a drone ship landing about eight minutes after liftoff. According to SpaceX, the first stage booster supporting tonight's mission is flying for the 17th time.
