Hmm, it should definitely show up on Satellite as well, at this link:

I'm not sure what the issue is — the only thing I can think of is that the event was not published to any of the default relays that Satellite uses for non signed in users. Are you signed in to Satellite? If you sign in Satellite will connect to your preferred relays so the event might show up.
