SENTRY

Survey and Early Notification of Threatening Reentry

A Kerbal Space Program mod that alerts you to asteroids on impact trajectories and incoming comets.

Features

• Alert window for asteroids and comets
• Filter by asteroids, comets, flybys, and impacts
• Audio alerts for important events
• Stock alarm clock integration to stop timewarp when asteroids hit the home body
• Stop timewarp when a threatening asteroid is discovered

If you have Kopernicus installed

This should work with the stock asteroid system as well as the Kopernicus asteroid system (though I haven't tested it), but you won't get comets with the Kopernicus asteroid system, which is active by default if you have Kopernicus installed (it's a dependency for most planet packs and Parallax Continued). You can switch to the stock asteroid system by changing
UseKopernicusAsteroidSystem = True
to
UseKopernicusAsteroidSystem = Stock
in GameData/Kopernicus/Config/01_DefaultConfig

Dependencies

• Click Through Blocker
• Toolbar Controller

Installation

• Install all dependencies
• Copy the SENTRY folder to the GameData folder of your KSP install

I used Claude Code for the plugin code. I'm not proficient with C# or the KSP codebase. That said, this isn't slop. Human thought, planning, and testing went into this.
