Overview of #287 Butch Wilmore — He Was Stranded in Space for 286 Days (Shawn Ryan)
This episode features retired U.S. Navy Captain and recently retired NASA astronaut Butch Wilmore. Ryan and Wilmore cover his 40-year service career (25 years with NASA), 464 total days in space (including 32+ hours across five EVAs), flying in five different spacecraft (Space Shuttle, Soyuz, ISS, Starliner, Crew Dragon), and the story behind being unexpectedly extended on orbit for 286 extra days after Boeing’s Starliner test flight problems. The interview mixes technical detail (suits, thrusters, carrier ops), candid mission storytelling (combat flights, shuttle launch, the Starliner anomaly), and reflections on leadership, faith, family, and preparation. Wilmore also summarizes lessons learned and why transparency and rigorous testing matter in human spaceflight.
Key topics covered
- Butch Wilmore’s background: Tennessee upbringing, football, electrical engineering, Navy aviator, test pilot, then NASA astronaut.
- Naval aviation and combat experience: A-7, F/A-18, carrier takeoffs/landings, Desert Storm missions.
- NASA career highlights: STS-129 (Space Shuttle), Soyuz long-duration missions, multiple spacewalks (total ~32 hours), commander roles.
- Starliner OFT/crewed flight problems: sequential thruster anomalies, degraded control, docking decisions, inability to return in Starliner.
- Extended stay on ISS: how the crew coped (food, routines, SpaceX Dragon seat modifications), return on Dragon.
- Spacesuit and EVA tech: costs, complexity, EVA preparation and hazards, SAFER jetpack.
- Spaceflight engineering lessons: testing, fault tolerance, software & hardware validation, mishap classification and institutional trust.
- Faith, leadership, family, and resiliency: Wilmore’s Christian faith as a guiding principle; leadership style and family priorities.
- High-level take on Mars and deep-space challenges: communications latency, atmospheric braking limits, need for in‑space manufacturing.
Notable quotes / soundbites
- “It’s a privilege to serve your nation.”
- “Aviate, navigate, communicate” — priorities when things go wrong.
- “Don’t get famous on a spacewalk.” (If you get untethered, you’ve failed.)
- Bible summary Wilmore uses as life anchor: God the Father planned to present God the Son with a redeemed humanity — repentance and trusting Jesus is the ultimate, eternal purpose.
- On Starliner: he emphasized preparation, transparency, and that NASA must ask the people who were on the controls when classifying controllability issues.
Timeline & career highlights (concise)
- Grew up in Mount Juliet, Tennessee; EE degree, played college football.
- Navy aviator → test pilot; flew A-7, F/A-18; 8,000+ flight hours, 663 carrier landings.
- Joined NASA; first shuttle flight STS-129 (Atlantis, Nov 16, 2009).
- Soyuz long-duration mission (2014–2015) — multiple months on ISS.
- Conducted multiple EVAs (five EVAs total across missions; ~32 hours).
- Commanded Boeing Starliner’s first crewed flight (OFT issues followed by crewed test).
- Ended with cumulative 464 days in space; was stranded an extra 286 days before returning on a Crew Dragon.
The Starliner incident — what happened (summary)
Mission intent
- Crewed test flight: verify rendezvous/docking, docked operations, undock and deorbit, and landing — certify a new U.S. crewed spacecraft.
Anomaly sequence (as Wilmore describes)
- Several thrusters (aft-firing clusters on service module) displayed reduced thrust; multiple thrusters were taken offline by the vehicle (FITR — Fault Indication/Response).
- Losses progressed from 1 → 2 → 3 → 4 thrusters down; spacecraft control degraded though crew maintained proximity and attitude manually.
- Crew and ground worked test firings to recover thrusters; some were recovered, others remained degraded.
- Wilmore emphasized the tactile feel: “control felt different” — precise on Day 1, then sluggish as thrust levels were reduced.
- Ground assessments, helium manifold leaks (small leaks existed; by return seven of eight manifolds showed leaks of some sort), and inability to fully bound the failure left Starliner unsuitable for crewed return.
- NASA initially classified it as a “high-visibility close call”; Wilmore argued for—and NASA later reclassified it as—a Type A mishap. A thorough investigation followed.
Outcome for the crew
- Crew docked safely to ISS and remained; mission became a long-duration stay.
- Because Starliner could not be confidently used for crew return, SpaceX Dragon seats were adapted (engineering foam seats/pallets) so the stranded crew could return safely.
- The crew returned on Crew Dragon after months on orbit (286-day extension for Wilmore and colleagues).
Technical and operational insights listeners found valuable
- Spacesuit/EVA tech:
- EMU (U.S. spacesuit) cost range: roughly $5–7M; a single EVA drill ~ $2M.
- EVA prep takes many hours (about 5 hours before hatch opening for purge & checks).
- SAFER jetpack exists as a contingency for an untethered astronaut.
- Onboard spacecraft flight control:
- Spacecraft operate with multiple fault tolerance layers; losing multiple thrusters rapidly can reduce attitude control to unsafe levels.
- FITR (fault detection) can automatically isolate underperforming thrusters.
- Carrier aviation:
- Carrier landing stopping distance is very short (touchdown to stop ~300ft); runway distances aboard ship vs. 7,000+ ft conventional runways are a dramatic difference.
- Night carrier landings remove peripheral cues — pilots rely on the visual landing aid (“the ball”) and centerline lighting.
- Long-duration living:
- ISS is modular volume comparable to several buses end-to-end; spares, cargo arrivals, and logistics require choreography.
- Food and life-support contingency planning matters — Wilmore used spare bags of food left on station early in the extension.
- Physical effects: fluid redistribution (puffy face), muscle and bone loss, neurovestibular impacts; intense daily exercise required (approx. 2–2.5 hours/day).
- Deep-space challenges:
- Mars entry/landing is hard because its atmosphere is thin (~1% Earth) — conventional aero-braking is much less effective; scaling mass to land humans is a fundamental engineering problem.
- Communication latency with Mars (minutes up to ~42 minutes round-trip) makes autonomy a requirement.
Leadership, faith, and personal lessons
- Leadership: surround yourself with experts, empower people, avoid micromanagement, focus on the mission, and replace people who cannot perform.
- Faith: Wilmore repeatedly points to Christian faith as foundation — contentment and perspective come from trust in God (“be anxious for nothing…”).
- Family: family sacrifice is constant in military/astronaut life; Wilmore intentionally flew items for his daughters to preserve legacy (rings, wings, flag from an EVA).
- Preparation: repeated mantra — “Preparation, preparation, preparation.” Test extensively and be ready for failure modes.
- Integrity & transparency: Wilmore stresses honest communication and that technical decisions must be supported by full reporting (and that astronaut input is critical for classifications tied to controllability).
Practical takeaways / recommendations
- For engineers & program managers: prioritize end-to-end hardware/software integration testing (iron bird, ASIL), aggressively pursue failure-mode discovery, and be transparent about mishap classification and root causes.
- For leaders: hire competent people, trust but verify, and focus on mission-critical priorities when under pressure.
- For individuals: build preparation and faith-based resilience; maintain relationships and leave a legacy intentionally.
- For space advocates: recognize the difference between publicity and safety; encourage investment in autonomy, in‑space manufacturing (3D printing), and robust entry/decel tech for deep-space goals.
Book / resources mentioned
- Butch Wilmore’s book: Stuck in Space: An Astronaut’s Hope Through the Unexpected (captures his Starliner story, faith perspective, and life lessons).
- Wilmore’s missions: STS-129 (Atlantis), Soyuz long-duration, Starliner crewed test (anomaly), Crew Dragon return.

Final impression
This episode is a mix of technical insider detail and human reflection. Wilmore provides unusually candid, tactile descriptions of what controlling a spacecraft feels like under degradation, how astronauts prepare and live on orbit, and why institutional integrity and rigorous testing are essential. He frames the Starliner episode as both an engineering/mishap case study and a faith-anchored story about resilience, duty, and stewardship of family and country — useful to listeners interested in aviation, human spaceflight, leadership, and personal faith.
