Introduction
You often face overwhelming technical challenges where failure means public disaster and lost investment. Traditional management models and rigid thinking fail when you must invent solutions to problems that have never been solved before.
Adam Steltzner and William Patrick show you how to build innovative organizations by embracing radical curiosity and rigorous discipline. You learn to navigate intense technical ambiguity through high-trust teamwork, constructive conflict, and absolute ego surrender.
The book guides you through six distinct phases of personal and organizational transformation.
- How do you transform from an undisciplined outsider into a rigorous engineer?
- What mental models help you solve seemingly impossible technical problems?
- How do you lead a high-stakes team through terrifying periods of total uncertainty?
1. From Chaos to Celestial Mechanics
Personal transformation and intellectual awakening begin when an individual confronts personal inadequacy through obsessive curiosity and rigorous discipline.
Curiosity acts as a spark that ignites a lifelong fire of thinking, exploration, and learning. A genuine spark breaks through educational paralysis and fear of failure, leading individuals out of dead-end paths into rigorous exploration of the physical world.
Extreme physical risk-taking in youth can stem from an underlying reaction against the paralyzing fear and denial seen in authority figures. Growing up with an intelligent father who refused to work out of fear of failure, children may cope by becoming human projectiles who push physical boundaries and break bones to escape that psychological cage. Adam Steltzner engaged in skateboarding in traffic and mountain biking at race-car speeds, breaking thirty-two bones before reaching adulthood.
A simple observation of celestial movement can trigger a profound intellectual awakening and shift one's life trajectory. Driving home from a band gig after midnight, Adam Steltzner noticed the constellation Orion shifting from the eastern sky to the western sky, which sparked his interest in celestial mechanics. Noticing basic astronomical patterns without any prior formal training can ignite deep intellectual curiosity about the physical laws governing the universe.
Success in demanding fields often relies on a constructive interference of personality disorders. Unusual personality traits and a desperate need to overcome personal inadequacies can combine to provide extraordinary motivation for mastering rigorous disciplines like math and physics. The author entered a monkish phase, shaving his head and abandoning music to catch up on missed education at the community college level after receiving an F+ in high school elementary algebra and geometry.
Dr. Stephen Prata at the College of Marin demonstrated the thrill of discovery, helping Adam Steltzner transition from a struggling musician to a physicist and engineer.
Groundbreaking engineering organizations thrive on a freewheeling, iconoclastic culture that embraces bold and unconventional methods. The Jet Propulsion Laboratory grew out of early rocket experiments conducted by self-taught enthusiasts in dry creek beds. This legacy of independence, unconventional beliefs, and risk-taking enabled the lab to lead American interplanetary exploration.
Early founders like Frank Malina and Jack Parsons blended rocket development with radical politics, alternative religions, and campfires in the Arroyo Seco, forming the Suicide Squad. The Jet Propulsion Laboratory occupies 177 acres of land rising into the San Gabriel Mountains, supporting five thousand regular employees and one thousand additional contractors in 1991, the year of the author's initial interview at the lab.
2. Mindsets and Engineering Philosophy
Effective problem-solving demands holding on to doubt, welcoming fresh perspectives, and connecting observable facts into coherent models.
Anxiety about unanswered engineering questions often drives you to jump into solution space too quickly. You must remain calm in openness and avoid assumptions until the deepest truth reveals itself.
While taking physics at the College of Marin, Steltzner wrote Hold on to the doubt! across his one allowed cheat sheet instead of filling it entirely with equations.
- Remain calm in the presence of openness and unanswered questions.
- Do not close off inquiry too soon to avoid running into incomplete solutions.
- Listen to all that the problem has to say without making assumptions until the deepest truth presents itself.
In October 1991, the author started working at the lab. NASA administrator Daniel Goldin challenged JPL staff in 1992 with the faster, better, cheaper approach, stating that a project with a twenty-for-twenty record proves they are playing it too safe. This strategy replaced massive, slow projects with smaller missions run by smaller teams, encouraging higher risk tolerance while NASA's budget was scheduled to shrink by 18 percent over the next decade alongside a reduction of 1,000 in JPL head count from its baseline of 5,500.
Newcomers possess a beginner's mind that spots operational gaps. Institutions must look past the awkward delivery of youthful observations to find essential virtues, while young employees need patience rather than expecting immediate advancement or recognition. At twenty-eight years old, Steltzner entered JPL and naively proposed creating a new cognizant analyst role to bridge the gap between designers and analysts, which his supervisor Frank Tillman viewed with total confusion.
True leadership and influence require stepping up and offering well-considered opinions without waiting for an official invitation.
Waiting around to be authorized to speak up or lead prevents you from gaining authority. Authority stems from high performance, well-articulated thoughts, and acting like the leader of a project before being officially appointed.
On the Champollion comet lander study, Steltzner broke down the complex anchoring problem into logical pieces and shared his reasoning with engineers Randy Lindemann and Chris Porter, leading to his official appointment by Dara Sabahi.
- Bring yourself to the team process by offering opinions in the absence of an invitation.
- Rise to the performance level of the job you want to have by simply doing the work.
- Exhibit leadership as a service function to facilitate collective performance rather than demanding power.
Cows represent raw data and observable facts without models, while bulls represent models, frames of reference, and causal connections between observations. Most engineering problems arise not from missing facts, but from failing to appreciate the links between them. When Mars Polar Lander was lost in late 1999, the team understood the basic facts, but failed to appreciate the connection regarding improper testing of a contact switch that could cause engines to fire prematurely at 80 meters or 262 feet above Mars.
High-performing technical teams embrace direct conflict and passion as necessary tools for uncovering physical truths. Stodgy missions rely on massive bureaucratic reviews and detached communication, whereas high-impact teams embrace fiery debates and emotional investment. Dara Sabahi stormed out of a meeting after Steltzner and Miguel San Martin improvised by proposing a separate daughter ship for the Comet Nucleus Sample Return mission instead of relying on a single vehicle.
3. Redesigning for Extreme Challenges
Simultaneous mission failures and increased payload requirements force a total architectural redesign and demand meticulous human-system engineering.
The Mars Climate Orbiter failed because of a mismatch between metric units and imperial pounds in a small-forces file, causing the craft to burn up. The Mars Polar Lander crashed because the computer mistook landing-leg deployment shocks for touchdown and shut off the engines prematurely 80 meters or 262 feet above the surface. Lockheed Martin built the 1999 orbiter and lander aiming to match the $350 million cost of Pathfinder, but both missions failed due to inadequate staffing and lack of thorough checks.
The maximum distance between Earth and Mars depends on orbital conjunction, reaching 249 million miles, while the minimum distance achieved once every twenty-six months is 33.9 million miles.
While Pathfinder's Sojourner weighed 25 kilograms or 55 pounds and relied on a stationary base station, the new Mars Exploration Rover or MER rovers Spirit and Opportunity weighed 173 kilograms or 381 pounds. They operated as autonomous field geologists with heavy scientific instruments, requiring a larger parachute, bigger rockets, and stronger airbags. The team realized that the stock Pathfinder landing system could not handle the much heavier rovers, prompting Dara Sabahi to recruit Adam Steltzner to lead structural and architectural changes.
Effective systems engineering requires designing the human communication network just as deliberately as the technical hardware. Because entry, descent, and landing components are tightly coupled across fluid mechanics, thermodynamics, and propulsion, engineers must work as an integrated collective rather than isolated specialists.
You can apply effective human-system engineering principles to your own projects:
- Understand teammates jobs as well as they do to build technical credibility.
- Encourage beginner-mind questions to push the team to deeper analysis.
- Limit frustration to specific behaviors rather than attacking the person.
- Host regular informal gatherings or team lunches to build trust and family feeling.
Steltzner instituted Thirsty Thursday pub crawls and rigorous team meetings, which helped engineers like Carl Guernsey and Ben improve each other's rocket and bracket designs through constant intellectual sparring.
During drop tests in Boise, Idaho, oversized parachutes repeatedly shredded because the structure was built to handle loads based on the uninflated model rather than the actual inflated shape. That shape placed opposite stresses on the Kevlar lines and seams. Testing the supersonic parachute on Earth required an altitude of 130,000 feet, and parachute drop tests were conducted in Boise in June 2002.
You can manage unforeseen physical behaviors in testing by applying specific diagnostic strategies:
- Bring in external troubleshooters and competitors for emergency triage.
- Utilize massive wind tunnel facilities to closely observe abnormal aerodynamic phenomena.
- Run parallel design and fabrication paths when time is too short for sequential iteration.
After multiple parachute failures, Steltzner brought in Langley troubleshooters Juan Cruz and Prasun Desai, consulted industry competitors, and eventually used Ames Research Center's wind tunnel with a test speed of 120 to 135 miles an hour to diagnose squidding caused by an oversized vent.
Decision-making driven by fear creates self-delusion, whereas curiosity-based exploration yields superior engineering solutions. Fear makes people demand fast, superficial answers because open questions cause anxiety, while curiosity allows engineers to pull apart and examine open questions calmly. Steltzner admitted that fear of not getting enough parachute drag caused him to push for excessive changes without fully listening to the balanced limits of the technical answers.
Leaders must be willing to look foolish and be wrong in public to encourage their teams to relentlessly hunt for the truth. People naturally fear being wrong and losing status, but intentionally taking the opposing side of a technical debate strips away ego and demonstrates that ideas matter more than hierarchies. Steltzner bet Rich Hund a beer at Lockheed Martin that he could not prove the structural need for a heat shield seal, taking the wrong side of the debate to force a deep engineering analysis that ultimately built camaraderie.
Intuition and subconscious data processing serve as an essential counterbalance to purely rational, minimal analysis. While explicit engineering relies on known knowns like mathematical equations, complex systems also require Spidey sense, an inner voice of judgment built from extrapolated experience that attempts to model unknown unknowns. Dara Sabahi trusted his Spidey sense to make bold architectural decisions, such as appointing Steltzner to lead mechanical systems on entry, descent, and landing despite his lack of traditional management experience.
4. Navigating the Dark Room
Overcoming insurmountable technical barriers requires surviving the terrifying Dark Room through absolute ego surrender and inventive mechanical solutions.
During the Mars Exploration Rover development, the team struggled for nearly a year with parachutes, air bags being destroyed by the Black Rock, and steel tapes breaking on descent-rate limiters before finding solutions through sheer persistence.
To guide your approach through difficult technical barriers, apply these methods:
- Stay calm and hold on to the doubt
- Listen to the problem without panicking
- Completely surrender the ego and stop trying to force existing solutions
- Allow the subconscious to combine with engineering judgment
Miguel San Martin designed transverse steering rockets backed by machine vision algorithms developed by Andrew Johnson to prevent air bags from hitting rocks at glancing, tearing angles due to parachute pendulum swings on Mars. The descent image motion estimation system and transverse impulse rocket system take multiple images of the ground, track craters and mountains, rectify the frames, and calculate ground speed to activate steering rockets precisely beneath the 20-meter or 66-foot bridle as the spacecraft descends at 150 miles per hour.
Engineers tested spare Pathfinder air bags at the Space Power Facility at Plum Brook Station in Sandusky, Ohio, finding that sharp rocks tore through up to six abrasion layers until the inner bladder solution was devised. The facility features a vacuum chamber 122 feet high and 100 feet in diameter, enclosed by concrete walls 6 feet thick with a 1 foot of steel lining, where air bags were tested at an impact speed of 30 miles per hour.
Tom Rivellini redesigned the descent-rate limiter for the 1,190-pound Mars Exploration Rover lander using a Kevlar line and capstan winch instead of a coiled stainless steel stainless steel tape, bypassing the spool entirely to prevent breakage under increased loads compared to the 800-pound Pathfinder lander. Following Spirit's landing, a tiger team investigated snatch force anomalies and successfully altered the parachute-deployment dynamic pressure from 830 to 835 pascals for Opportunity's landing after spending $650,000 on liquid nitrogen for vacuum chamber testing within a $1 million test matrix.
Effective engineering leadership requires balancing deep critical questioning with avoiding paralysis by analysis, while entirely stripping away personal ego and performance anxiety. When Steltzner accepted a pre-existing SA/SPaH core-sampling design for the Mars Science Laboratory without critical questioning because he feared appearing indecisive, it ultimately cost the team two years of development work.
When you design early spacecraft architectures, you must start small and aggressively reduce excess mass because hardware naturally accumulates weight during development. The Mars Science Laboratory team cut the initial rover mass from 900 kilograms or 2,000 pounds down to 500 kilograms or 1,100 pounds by eliminating one robotic arm and one RTG, though Curiosity eventually approached its original inherited weight before launching in 2011.
During a brainstorming session in room 201 of Building 158 in September 2004, fourteen entry, descent, and landing engineers conceived the Sky Crane architecture, which was later reviewed and approved by an external board including astronaut Harrison Schmitt in Monrovia, California.
To execute this complex landing phase for extremely heavy planetary rovers, you follow specific mechanical steps:
- Keep the descent stage and rover together until agile flying is complete and horizontal motion is killed
- Lower the rover on a bridle only when vertically positioned just meters above the surface
- Reduce throttle settings by half upon weight deposition to confirm landing via onboard logic
- Cut the cables with pyrotechnics and fly the descent stage away
This final deployment leaves a distance of 7.5 meters or 24.5 feet on the triple bridle between the rover and the descent stage while maintaining a continuous descent rate of ¾ of a meter or 2.5 feet per second toward the surface.
5. Organizational Art and Simple Truths
True leadership is the art of warping organizational structures to fit human personalities while relentlessly simplifying designs using Occam's razor.
The Jet Propulsion Laboratory operates as a federally funded research and development center administered by the California Institute of Technology rather than being government-owned. While traditional NASA field centers move slowly with civil service protections, JPL operates on a fire-at-will, merit-based approach that demands tangible delivery in exchange for greater operational freedom.
Making things too complex is a fast way to fail. You should aim for the simplest, lowest-risk solution that is just right enough.
- Check if your device or robot does what it is supposed to do as planned.
- Look for the simplest, lowest-risk way of solving a problem.
- Cleave away all that is not needed using Occam's razor.
When groups spend careers studying abstract mission concepts one or two decades away, they engage in contemplation that is not practical. The Langley Research Center team spent years studying aerodynamic flight and became emotionally committed to complex lifting solutions like trim tabs because they lacked real-world flight development experience. Paper studies often allocate 1.7 seconds to a spacecraft transition, creating a dangerous illusion of guaranteed success.
Langley advocated for a trim tab on the 4.7 meters or 15.4 feet launch vehicle nose fairing diameter to provide lift. The design created right-angle corners 10 inches in scale length and exceeded the 2 to 3 inches size limit for thermal protection material testing at Ames wind tunnels. Steltzner replaced the trim tab with a simpler weight-offset approach.
Lockheed Martin propulsion expert Kevin Johnson warned that placing descent stage engine nozzles beside the rover would cause severe radiative heating. The team dismissed him, but 6 months later verification proved the model underestimated heating, forcing 1 year of total time required to complete engine changes and verification ripples.
Control engineers often spend 5 times the effort to achieve a 10 percent greater return through optimization. Steltzner appointed Miguel San Martin to head guidance and navigation, applying an uncoupled spacecraft control approach across the history of JPL developing spacecraft controllers for nearly seventy years.
- Think carefully about the entire cast of team members and their stated or unstated wants and desires.
- Consider the strengths and weaknesses of everyone, including yourself, and how each might grow.
- Warp and distort the traditional project organization structure to conform to the specific individuals involved.
6. The Right Kind of Crazy
Defending radical engineering architectures to leadership requires taking full responsibility for communication and managing nonlinear material failures.
Adam Steltzner presented the unusual Sky Crane landing architecture to NASA administrator Mike Griffin at NASA headquarters in Washington, DC, wearing a blazer, jeans, and cowboy boots. Griffin ultimately approved it, stating it was "the right kind of crazy". The 90-minute review session included 30 people assembled in the small amphitheater for the NASA briefing. When presenting a radical engineering solution to high-level leadership, your goal is to win approval for the idea rather than scoring personal debating points against critics.
Effective communication requires taking full responsibility for the impact of information on the listener. Aerodynamicist Juan Cruz showed terrifying precursor videos of Viking-era parachutes melting and tearing apart at Mach 3+ to the review board, causing them to panic and demand two extra years of redundant testing. This mistake incurred an extra ten million dollars in costs over two years.
Complex materials can experience unexpected chemical or physical breakdown at moderate conditions. James Reuther from Ames Research Center called the author during his critical design review presentation to report that SLA-561V material tested for the Orion moon mission had mysteriously vanished under moderate heating conditions in the arc jet. The Mars Science Laboratory would hit the Martian atmosphere at 13,000 miles per hour. Lockheed Martin integrated PICA tiles into the new heat shield in nine months, a process that normally takes 18 to 24 months.
The team commissioned a single massive 21.5-meter parachute instead of the traditional two-parachute design, testing rigid parachute models in wind tunnels at Glenn and Ames research centers to understand wake-induced collapse. The single big parachute was planned to open at a Mach number of 2.25. The historical Viking mission parachutes had a diameter of 16.1 meters, while the new version measured 70.5 feet. Wind-tunnel tests observed wake collapse behavior turn on and off in a Mach number range of 1.5 to 2.4.
Chris Voorhees's mobility team inadvertently requested a waiver to skip Earth-gravity testing for the rapid wheel drop-and-jerk mechanism. This oversight forced the team to perform late nonlinear stress analyses using a hydraulic ram to prove the system would survive. Each of the five radar pencil beams had a width of 3 degrees. Rover mobility was deployed at an altitude of 20 meters above the ground in the Sky Crane maneuver. Six months passed before you or the author discovered the waiver had been requested without landing team oversight.
