If you mean Hera the mission/spacecraft , there isn’t a user-facing way to “extend” an end-of-tour the way you would with a travel booking. The public information I found points to Hera being an ESA mission with a fixed schedule, not something you can change through a personal account or app.

What the search shows

Hera is described as a spacecraft mission to the Didymos/Dimorphos system, with launch and arrival milestones set by ESA. That means the wording “end of tour” is probably not a standard official feature name in the public mission material I found.

If you meant something else

If “Hera” is the name of:

  • a travel platform,
  • a game,
  • a workplace system,
  • or a forum/product nickname,

then I’d need the exact app, site, or organization name to give the right steps.

Best next step

Reply with:

  • the full name of “hera,”
  • where you’re seeing “end of tour,”
  • and whether you want to extend a booking, shift a deadline, or change a mission timeline.

Then I can give you a precise answer.
