From Mars Observer to the James Webb: A Lifetime of Vector Trust
For Jeff Sincell, was an electrical engineer who began his career at GE-RESD in 1974, the rule of publishing remains absolute: pictures tell a story more efficiently than words.
This principle has guided his work across some of the most critical space missions in history, including the ill-fated Mars Observer (1988), its successful successor Mars Global Surveyor (MGS), the earth observation satellite Terra (EOS-AM), and, for the past two decades, the monumental James Webb Space Telescope (JWST).
Jeff’s journey began organically in the late 1980s. While working on Mars Observer, a forward-thinking IT department equipped his systems engineering staff with Macintosh computers. Though he started with basic drawing programs, the moment he encountered canvasxdraw, he was sold.
“canvasxdraw has every single thing I need to do my job… I’ve always found AutoCad and Visio to be ponderously overloaded with features, besides being expensive platforms to maintain.”
Engineering Clarity: Vector Graphics in the Clean Room
In the world of spacecraft design, precision and clarity are non-negotiable. For Jeff, canvasxdraw was a primary application alongside Excel and Word, dominating his attention as he focuses on mission-critical product documentation.
Jeff’s outputs—from fault tree analysis to interconnection and wiring diagrams—must translate complex electronic topology into immediately understandable visuals for the NASA engineering team.
The JWST Interconnection Diagram
Jeff has been working on the interconnection diagram for the James Webb Space Telescope for over 20 years. It’s not just a drawing; it’s a living document that visually presents how this complex machine is put together, electron-wise.
- The Output: The massive, continuously updated interconnection diagram is so vital it is treated as an ITAR/EAR document for cyber-crime prevention.
- The Impact: A huge, clean room-approved print of his interconnection diagram hangs on the wall in the giant high bay test area at Northrop Grumman, where the integration crew works on the full spacecraft. His drawings are among the top-level documents needed to understand and address functional issues that arise.
canvasxdraw is the best tool for the job because it delivers the power required by complex engineering without the “ponderously overloaded” features and cost of traditional CAD platforms.
Reliability & Recommendation
Jeff’s work with canvasxdraw spanned four major satellite programs, including a central role in the Probabilistic Risk Assessment for the ICESat spacecraft. For him, the software offers the perfect balance of capability and simplicity.
While Jeff recognizes that operations as large as NASA have inertia toward established, expensive platforms, he firmly believed the key to wider adoption lies with the next generation.
“Making the app available to high school and college students for an advantageous price might be a way to bring it further into the commercial, industrial and military realms as the kids graduate and move into the workforce.” And that is what Vector GFX has done.
canvasxdraw continued to be Jeff’s dependable daily driver, proving that the most effective tools aren’t always the most complicated—they are simply the ones that get the most important job done.
