Sarah Gillis Signed Memorabilia: First Woman to Perform a Commercial EVA

Sarah Gillis flew as mission specialist on SpaceX Polaris Dawn in September 2024. On Mission Day 3, she exited Crew Dragon Resilience and performed a spacewalk at approximately 700 kilometers altitude — becoming the first woman to conduct a commercial extravehicular activity. Gillis is a SpaceX astronaut operations engineer who trained the Crew Dragon astronauts — then flew herself. Her signed memorabilia represents one of the most undervalued entries in the current commercial space market.

Historical First: The Permanent Record Value

Collectors place enduring premiums on permanent firsts. Valentina Tereshkova, first woman in space (Vostok 6, 1963), commands $1,500–$4,000 for authenticated signed items today. Alexei Leonov, first human EVA (Voskhod 2, 1965), commands $2,000–$6,000 for signed items. Sarah Gillis holds the commercial-era EVA record for women — a category that will remain permanently attached to her name regardless of how many commercial missions follow. That permanence is the foundation of long-term value.

Gauntlet Gallery's Assessment

Gillis items are currently priced as if she were a mid-career commercial crew member with no distinctive record. That pricing is incorrect. She holds a permanent first that will be cited in history books. The entry point is now. In Gauntlet Gallery's collection framework, Gillis signed pieces belong in the same category as early Tereshkova items circa 1975 — not yet recognized at their long-term value.
