"This time, however, rather than the poor weather that aborted Falcon 9’s first three launch attempts, the fourth scrub was caused by a cruise ship fouling the range and trespassing inside a US Coast Guard keep-out zone that’s been public for the better part of a week."
"By all appearances, the ship responsible appears to have been Royal Caribbean’s Harmony of the Seas, which was headed straight into the Coast Guard’s keep-out-zone about 20 minutes before liftoff and veered south – away from the zone – around 10 minutes later. However, that’s not certain as a large number of cruise ships operate in or around the southeasterly corridor Falcon 9 was scheduled to overly between Florida and the Bahamas, making it possible that a different ship was at risk of entering the keep-out zone dozens to hundreds of miles downrange."
"While just a part of rocketry, this scrub was particularly annoying because it came on a day with near-perfect weather after three consecutive weather-related scrubs. The US military’s 45th Space Wing had also explicitly warned boaters and the general public of the unusual southerly launch trajectory and encouraged them to double-check exclusion zones. Further, had Falcon 9 been able to launch, perfectly clear skies and a liftoff scheduled about 15 minutes after sunrise could have created a spectacular light show visible for one or several hundred miles in every direction as Falcon 9 rose back into direct sunlight. The weather forecast on CSG-2’s backup window (6:11 pm EST, Jan 31) still predicts excellent conditions but clear skies are never guaranteed."
"Ultimately, a fouled range – and, in general, any non-technical launch delay – is just an inconvenience for SpaceX and its customer. Nonetheless, each scrubbed launch likely costs the company several hundred thousand dollars and wastes hundreds or even thousands of work-hours. Additionally, given SpaceX’s plans for as many as 52 Falcon launches this year, a few days of delays can quickly become a significant issue if repeated multiple times. With any luck, that won’t be the case and CSG-2’s fouled-range delay will be just a fluke for SpaceX and the Florida launch range."
"Thanks to the cruise in question, SpaceX now appears likely to have a Falcon 9 launch scheduled on Monday, Tuesday, and Wednesday (Jan 31, Feb 1, and Feb 2). CSG-2 continues to target a 6:11 pm EST (23:11 UTC) liftoff – just on January 31st, this time around. SpaceX will likely delay Starlink 4-7 another 24 hours, pushing the mission to sometime around 2pm EST (19:00 UTC), February 1st. Last, Falcon 9 remains on track to launch the NROL-87 spy satellite mission remains around 12:18 pm PST (20:18 UTC), February 2nd. There’s a possibility that Starlink 4-7 is now NET February 3rd but that has yet to be confirmed. Beyond those three missions, SpaceX has as many as three more Starlink missions tentatively planned for February after NROL-87."
