While the full version of Kerbal Space Program is now a paid product owned by Take-Two Interactive, the old demo versions have historically been made available for free by Squad, the original developers.
However, a word of caution: The official links for the 0.15 Demo on the Kerbal Space Program website have largely been retired in favor of newer demo versions or the full store page.
For those seeking the specific 0.15 build, gamers often turn to archival software repositories.
If you buy via Steam, you can download any previous version, including v0.15.
Note: GOG Galaxy also offers legacy downloads, but their archive usually starts around v0.18. Steam has the most complete historical library.
Kerbal Space Program 0.15 is a fascinating piece of gaming history. It allows you to see the humble beginnings of the complex physics simulator that would eventually teach millions about orbital mechanics.
If you are looking for a free download, the safest bet is to download the Official Demo. If you want the specific 0.15 experience, it is highly recommended to purchase the game (which often goes on sale for a low price) to support the developers and then access the legacy files through legitimate channels. Avoid "cracked" downloads to keep your PC safe from malware.

If you are looking for older versions or the demo, here are the legitimate ways to find them: 1. The Official KSP Demo
Squad released a free demo version of KSP (based on early versions like 0.13.3) to allow players to try the game. While version 0.15 specifically added features like spaceplanes and the SPH (Spaceplane Hangar), it was a paid update.

Use the dropdown menu to see available previous versions. (Note: 0.15 may not always be listed, as Steam's archive typically starts at version 1.0 or slightly earlier). 3. The KSP History Project (Community Archive)
The KSP community has a long-standing "Ancient Versions" thread on the Official KSP Forums. Users often share links to the very early freeware versions (prior to 0.14, which is when the game became paid). Freeware versions: Versions 0.7.3 through 0.13.3 were free.
Version 0.15: This was the second paid release. There is no legal way to download 0.15 for free unless you purchased the game during its early alpha stage. ⚠️ A Note on Safety
