Project Hail Kary Continued

A KSP mod that recreates Andy Weir's "Hail Mary" ship from Project Hail Mary, updated for modern Kerbal Space Program.

Overview

Project Hail Kary Continued is an updated version of the classic Project Hail Kary mod, now compatible with KSP 1.8.x through 1.12.x. This update rebalances Astrophage for stock delta-V calculations, adds scaleable part families, and introduces additional engines and tanks inspired by Andy Weir's novel "Project Hail Mary".

Features

• Astrophage Resource: Rebalanced density and pricing so stock delta-V tools work without plugins
• Astrophage Engines: A complete family of drives powered by Astrophage
• Mini Astrophage Engine and Booster variant (0.625 m)
• Astrophage Propulsion System and Booster (2.5 m)
• Astrophage Heavy Drive (3.75 m)
• Astrophage Titan Drive (5 m flagship engine)
• Astrophage Vernor Engine (RCS thruster)
• Astrophage Fuel Tanks: Matching tank lineup for every stack size
• Mini Tank (0.625 m), 1.25 m Tank, 2.5 m Tank, Size 3 (3.75 m) Tank, and 5 m Superheavy Tank
• Optional TweakScale: Native configs let every engine and tank scale cleanly with TweakScale if installed
