Main Facts: Accelerating Commercial Space Operations
In a recent broadcast of Space Minds—a video and audio podcast series produced by SpaceNews—host Mike Gruss sat down with Laura Crabtree, Chief Executive Officer and co-founder of Epsilon3, to discuss the structural and operational transformations required to scale modern space companies. Crabtree, a former SpaceX systems engineer and astronaut trainer, offered crucial insights into how aerospace organizations can optimize their internal workflows, streamline assembly, integration, and testing (AI&T) procedures, and drastically reduce the time needed to bring space systems from concept to flight readiness.
At the core of the discussion is a pressing industry challenge: while spacecraft technology, propulsion, and payload capabilities have advanced rapidly over the last two decades, many operational workflows, testing protocols, and compliance procedures remain tethered to outdated methods. Epsilon3, under Crabtree’s leadership, develops software platforms engineered specifically to modernize build, test, and operational workflows for complex engineering projects across space, defense, and advanced manufacturing sectors.
During the interview, Crabtree emphasized that the key to increasing organizational velocity lies in dismantling legacy operational roadblocks—specifically those surrounding procedure management, real-time data collection, hardware testing, and regulatory certification. By shifting from static paper binders or unintegrated digital documents to dynamic, web-based operating platforms, space startups and established prime contractors alike can execute hardware assembly and flight operations with significantly higher efficiency, safety, and traceability.
Chronology: The Evolution of Spaceflight Procedures and Workflow Tools
To understand the operational bottlenecks currently facing the space industry, it is necessary to examine how procedures and test operations have evolved over the past six decades.

+-----------------------------------------------------------------------------------+The Apollo and Space Shuttle Eras (1960s–1990s)
During the early decades of human and robotic spaceflight, procedure execution relied entirely on paper documentation. Engineering sign-offs, step-by-step assembly guides, and test check-lists were printed in massive flight and ground operation binders. Any modification to a procedure required manual "redlining"—writing corrections on physical paper—followed by lengthy peer-review cycles before reprinting. While this process maintained strict oversight for missions like Apollo and the Space Shuttle, it was resource-intensive, slow, and prone to human error in record-keeping.
The Commercial Space Revolution (2000s–2010s)
The rise of commercial space companies in the mid-2000s fundamentally disrupted hardware design and launch cadence. Companies like SpaceX introduced rapid iterative development, building and testing hardware at an unprecedented pace. During her time at SpaceX, Laura Crabtree was directly involved in this transition, serving as a dragon systems engineer and playing a pivotal role in training NASA astronauts for the historic Crew Dragon Demo-2 mission in 2020.
However, as commercial space scaled, many companies struggled with software infrastructure. Teams often relied on a mix of legacy enterprise software, custom-built internal scripts, and basic spreadsheets. While these custom tools worked for single missions, they frequently failed to scale when manufacturing turned to mass-production satellite constellations or frequent launch schedules.
The Rise of Purpose-Built Aerospace Software (2021–Present)
Recognizing that aerospace companies across the globe were spending valuable engineering hours reinventing operational software tools internally, Crabtree co-founded Epsilon3 in 2021. The objective was to provide an off-the-shelf, secure, and flexible operational platform designed explicitly for complex hardware testing, assembly, and mission control.
By 2024, as space access expanded globally, SpaceNews launched its Space Minds podcast series to provide a platform for industry executives like Crabtree to share strategies on how modern management, agile engineering, and specialized software tools are shaping the future of space exploration.
Supporting Data: The Quantitative Pressure on Aerospace Testing and Assembly
The demand for software optimization in the space industry is driven by clear economic and operational metrics. Over the past decade, the global space economy has expanded rapidly, placing unprecedented demands on assembly line efficiency, testing throughput, and regulatory compliance.
Global Launch Cadence Acceleration
The frequency of orbital launches has surged dramatically over the last five years, creating immediate operational pressure on launch site operations, range management, and launch vehicle preparation.
| Year | Total Global Orbital Launch Attempts | Commercial Constellation Satellites Deployed |
|---|---|---|
| 2019 | 102 | ~500 |
| 2021 | 145 | ~1,800 |
| 2023 | 223 | ~2,900 |
| 2024 (Proj.) | 250+ | 3,500+ |
Operational Bottlenecks in Hardware Manufacturing
According to industry studies on aerospace manufacturing performance:
- Administrative Drag: Engineers and technicians in traditional aerospace environments spend between 30% and 40% of their time searching for documentation, manually filling out paper/PDF test logs, or re-entering test telemetry into separate tracking databases.
- Error Rates in Manual Data Entry: Manual transfer of assembly sign-offs and test values results in non-conformance logging delays, extending the timeline for Root Cause and Corrective Action (RCCA) investigations by up to 50%.
- Testing Delays: Hardware-in-the-Loop (HITL) and integrated assembly testing frequently represent the single largest delay in spacecraft schedules. Streamlining live procedure execution and real-time telemetry tracking can reduce total assembly, integration, and test (AI&T) cycle times by 20% to 35%.
These statistics highlight why operational platforms have transformed from minor IT back-office conveniences into core operational infrastructure for space companies attempting to remain competitive in a capital-constrained market.
Expert Insights: Laura Crabtree on Operational Bottlenecks and Safety
In her conversation with SpaceNews host Mike Gruss on Space Minds, Laura Crabtree drew upon her extensive operational background to break down the specific strategies companies can use to eliminate bottlenecks without sacrificing mission assurance.
Modernizing Assembly, Integration, and Testing (AI&T)
Crabtree noted that one of the most common mistakes emerging space companies make is treating software as an afterthought during hardware development.
"When you look at how hardware moves through a factory floor or a test site, the friction almost always happens at the intersection of execution and data capture," Crabtree highlighted during the podcast. "Engineers need real-time feedback. If a technician is executing a critical test sequence on a propulsion system or a satellite bus, they shouldn’t be fighting with a static document or waiting days for sign-offs. They need software that acts as a live, interactive partner in the shop floor and control room environments."
Removing Bottlenecks in Certification and Testing
Verification and certification represent major hurdles for commercial companies, particularly those supplying hardware to NASA, the U.S. Space Force, or commercial launch providers. Testing must be fully documented, auditable, and traceable to specific engineering requirements.
Crabtree pointed out several operational techniques to overcome these roadblocks:
- Single Source of Truth: Unifying manufacturing execution, procedure running, and anomaly tracking under one software interface eliminates discrepancy gaps between design and operational teams.
- Automated Anomaly Capture: Enabling technicians to automatically flag anomalies during test execution ensures that non-conformances are immediately routed to quality engineers, avoiding downstream assembly delays.
- Iterative Test Execution: Building procedure frameworks that allow rapid revisions while maintaining a complete historical audit trail ensures companies satisfy strict regulatory requirements without halting shop-floor activity.
Balancing Speed with Flight Safety
Addressing concerns that rapid execution might compromise mission success, Crabtree emphasized that digitized, modern operational systems actually increase flight safety. Human spaceflight training—such as her work preparing crew members for SpaceX flights—requires absolute fidelity in procedures. Digitized workflows enforce strict constraints, prevent skipped steps, record precise timestamped data, and ensure that only fully qualified hardware makes it to the launch pad.
Strategic Implications for the Aerospace Ecosystem
The insights discussed in the Space Minds episode reflect a broader paradigm shift across civil, commercial, and national security space sectors.

+------------------+ +-------------------+ +-------------------+1. National Security and Defense Acquisition
The U.S. Department of Defense and the Space Development Agency (SDA) are increasingly prioritizing rapid acquisition models, shifting away from multi-billion-dollar single satellites toward proliferated architecture in Low Earth Orbit (pLEO). National security space acquisitions now require defense contractors to build, test, and launch hundreds of satellites on tight deadlines. Modern procedural and operational software platforms enable defense prime contractors to adopt agile software practices required to meet these rapid delivery timelines.
2. Democratization of Spaceflight Capabilities
Historically, only major prime contractors with massive internal IT budgets could afford to build proprietary software suites to support hardware assembly and flight operations. Off-the-shelf enterprise platforms like Epsilon3 level the playing field, allowing venture-backed startups and mid-tier aerospace suppliers to operate with the same operational efficiency and rigor as industry giants from day one.
3. Long-Term Exploration and Deep Space Operations
As the space industry prepares for long-term lunar habitation under NASA’s Artemis program and the commercial transition of Low Earth Orbit post-International Space Station (ISS), ground and space operations will grow increasingly complex. Distributed systems, autonomous hardware, and off-nominal remote troubleshooting will require highly flexible software environments.
The ongoing discussions highlighted by Space Minds illustrate that the future of space exploration depends as much on the software infrastructure governing ground execution as it does on rocket engine efficiency or orbital mechanics. By modernizing procedural execution, eliminating testing friction, and integrating continuous feedback loops, the aerospace industry is establishing the operational foundation required to sustain high-cadence, cost-effective spaceflight for decades to come.
