Logo SSI - History, Design,Usage Guidelines & Download (2026)

TL;DR

The SSI logo is the visual identifier of the Stanford Spaceflight Initiative (now known as Space Systems International) and the Safe Superintelligence Inc. It has evolved through four major versions (2012, 2015, 2020, 2024). Each version reflects a shift in branding focus-from a Stanford “S” with a rocket to a clean, abstract symbol usable worldwide.

1️⃣ What the SSI logo is & why it matters

Why it matters: A consistent logo builds trust, protects intellectual property, and ensures SSI is instantly recognizable across research papers, grant applications, and media coverage.

2️⃣ Design Mechanics - How the logo is built

• Geometry: A 45° rotated hexagon (60 mm side) encloses a stylised “S” formed by two intersecting arcs (radius 30 mm).
• Colors:
  • Primary: #0064A4 (deep teal) - used for the “S”.
  • Secondary: #00A9E0 (gradient accent) - optional for digital media.
• Typography (when paired with logotype): Montserrat Bold, 24 pt, letter-spacing 0.5 pt. Learn more about the BTS SIO cyber security pathway in the BTS SIO cyber security guide.
• File formats: SVG (vector, 100 % scalable), PNG (transparent, 300 dpi), EPS (print-ready).

3️⃣ Use Cases - Where & how to apply the logo

Key rule: Preserve a clear-space margin equal to the height of the “S” on all sides; never crop or rotate the logo.

5️⃣ Quick-Start Embedding Code (HTML/CSS)

<!-- SSI logo - responsive SVG -->
<img src="/assets/logo/ssi-logo-2024.svg"
     alt="SSI - Safe Superintelligence / Stanford Spaceflight Initiative"
     style="width:120px; height:auto;">

/* Ensure contrast on dark backgrounds */
.logo-ssi { filter: invert(0%); }   /* use on light bg */
.logo-ssi.dark-bg { filter: invert(100%); } /* use on dark bg */

Q2: Do I need to pay a licensing fee?
A: No, the logo is free for non-commercial and academic use. Commercial use requires a signed agreement.

Q3: What if I need a monochrome version? For insights on critical OpenSSL vulnerabilities, see the OpenSSL 2025 vulnerability analysis.
A: Convert the SVG to black (#000000) or white (#FFFFFF) while preserving the clear-space margin; this is permitted for one-color print runs.

Q4: How often is the logo updated?
