Week in Space Data, every Friday.

The whole ascent, low on the horizon. This is the Space Coast itself: you will see the pad, hear the rumble a few seconds after ignition, and feel a Falcon Heavy or SLS in your chest.
Liftoff itself is behind the curve of the Earth, but the rocket rises into view within seconds and you follow it for two to three minutes. Night and twilight launches are spectacular.
Directly across the river from LC-39; free, crowded for big launches.
Closest public beaches to SLC-40 and SLC-41; Jetty Park has a parking fee.
Paid, closest sanctioned viewing for select launches.
Making the trip? The full Cape Canaveral viewing guide has the pad-side spots, road closures and timing.
The whole ascent, low on the horizon. Cocoa Beach & Titusville is about 17 miles (27 km) from SLC-40, Cape Canaveral SFS, bearing 6° (N). Liftoff itself is behind the curve of the Earth, but the rocket rises into view within seconds and you follow it for two to three minutes. Night and twilight launches are spectacular.
Face N (6°) toward Cape Canaveral. The rocket rises from that point on the horizon and arcs downrange: for Cape Canaveral launches that generally means east or northeast over the Atlantic.
Two to three minutes for the first stage, sometimes longer at night when the second-stage plume is sunlit. Twilight launches, just after sunset or before sunrise, produce the biggest, longest-lasting displays.
