Where to look
A rocket lifts off below the horizon for distant viewers, then climbs into view as it gains altitude and flies downrange. Closer to the pad you'll see it within seconds; a few hundred miles away it can take three to six minutes to rise over the horizon. Find an open view in the direction shown for your city and start watching at liftoff.

Before you go
- Launch times change: scrubs and delays are common. Re-check the day of.
- Clear skies matter. Low cloud near the pad or along the trajectory can hide the rocket.
- Twilight launches are the most dramatic; daytime launches are the hardest to see at distance.
- Trajectory and timing here are estimates from a representative ascent profile.
