Overcoming Triskaidekaphobia in Modern Aerospace
For decades, the number 13 has carried a heavy weight in space exploration. From the harrowing experience of Apollo 13 to the deliberate avoidance of the number in shuttle designations, triskaidekaphobia—the fear of the number 13—has occasionally influenced mission planning.
In the past, this superstition led to complex workarounds. For instance, NASA managers once replaced the intuitive numbering system after the ninth space shuttle mission. What should have been STS-13 was instead designated as STS-41-C. This data-driven system used the fiscal year, launch site and launch order to avoid the unlucky number, a decision driven by former NASA Administrator Jim Beggs.
However, a trend is emerging where agencies are shifting from avoidance to embrace. The upcoming SpaceX Crew-13 mission represents a pivotal moment, marking the first time NASA has assigned a crew to a mission “13” since the Apollo 13 era. This shift suggests a move toward honoring legacy rather than fearing historical anomalies.
Visual Legacies: How Mission Patches Map the Future
Modern mission patches are evolving into complex storytelling tools that bridge the gap between historical milestones and future ambitions. The Crew-13 emblem is a prime example of this trend, utilizing “imitation” as a form of respect for those who paved the way.

The design incorporates several strategic nods to the Apollo 13 astronauts. Key elements include:
- The Golden Dragon: A dual reference to the SpaceX capsule and the golden horses found on the Apollo 13 insignia.
- The Orbital Bridge: The dragon’s tail wraps around Earth, symbolizing a connection between the International Space Station, the moon, and Mars.
- Classical Design: The use of Roman numerals (“XIII”) and the omission of crew names directly mimic the design elements from nearly 60 years ago.
By integrating these symbols, NASA is not just identifying a flight but creating a visual lineage that connects the early lunar missions to the current era of commercial crew rotations.
The Collaborative Bridge to Moon and Mars
The composition of the Crew-13 mission highlights a continuing trend of deep international integration. The crew consists of Jessica Watkins and Luke Delaney from NASA, Joshua Kutryk from the Canadian Space Agency, and Roscosmos cosmonaut Sergey Teteryatnikov.
This multinational team will serve as members of Expedition 75 and 76, conducting scientific investigations and technology demonstrations. These efforts are not isolated; they are essential building blocks for the next phase of exploration. The goal is to prepare humans for future missions to the moon and Mars, benefiting people back on Earth.
We are already seeing this progression in action. Recent milestones include the Artemis II mission, a crewed flyby of the moon that broke the distance record previously set by the Apollo 13 crew. Notably, astronauts Reid Wiseman and Christina Koch—who previously flew on Soyuz TMA-13M and Soyuz MS-13—were part of this record-breaking journey.
