Tonight NASA's Double Asteroid Redirection Test impacts on the moon Dimorphos of the asteroid Didymos.
The goal: Change Dimorphos' orbital period by 10 minutes.

I made a countdown that will count until the last second before the impact: https://earthmoon.glitch.me/space/specials/dart-impact-countdown/.

This puts the impact at 05:14:20 UTC on September 27, 8 hours later than the actual time.

Added after 4 hours 36 minutes:
Impact has now happened (~20 minutes ago, even though EarthMoon's countdown says there are about 7.5 hours left...)
NASA article and images, in case you missed it.

Didymos looks similar to Bennu if you ask me. Very cool that we finally got to see an asteroid moon up close!

The countdown worked correctly for me.
Maybe it's just the time zone offset.
