This is why launch pads have lightning towers.
Lightning crackled today (Aug. 27) over Launch Pad 39B at NASA’s Kennedy Space Center in Florida, which will host the highly anticipated liftoff of the agency’s Artemis 1 moon mission on Monday morning (Aug. 29).Â
The bolts came close to the Artemis 1 stack — a Space Launch System (SLS) megarocket topped by an Orion crew capsule — with several even hitting Pad 39B’s lightning towers.

There’s no cause for alarm; the towers were doing their job, shunting dangerous strikes away from valuable spaceflight hardware. One of 39B’s three towers was similarly struck in early April during an Artemis 1 fueling test, for example, and the SLS and Orion emerged unscathed.
Artemis 1 is the first mission of NASA’s Artemis program of lunar exploration, as well as the debut flight of the SLS. The powerful rocket will launch Orion on an uncrewed mission to lunar orbit that will last six weeks from liftoff to splashdown. The main goal is to demonstrate that both vehicles are ready to start launching astronauts to the moon and other deep-space destinations.
The weather isn’t great on the Space Coast today, as the lightning strikes show. But it’s expected to clear up considerably by launch day; weather forecasters with the U.S. Space Force say there’s a 70% chance that Mother Nature will cooperate on Monday morning.
If the weather or technical issues nix that liftoff attempt, however, NASA has two backup opportunities in the current launch window to shoot for — Sept. 2 and Sept. 5.
