Starlink has not only introduced new ideas into the manufacturing process but has also led to new ideas around data ingestion and storage. “When you try something new for the first time, like you change a fundamental configuration of the rocket, it’s important to be able to analyze that data,” says Sepanloo. SpaceX has helped pioneer the idea of reusable rockets, which makes data on flight performance especially interesting. The second stage is discarded after use, but the booster (first stag...

For the team focused on the software outside of the vehicles, the big change has been less about the programming languages they use and more about the diversity of projects they support. “The interesting thing to me is that we have scaled what essentially feels like four parallel businesses: commercial payload delivery with Falcon, human spaceflight with Dragon, a global internet service provider with Starlink, and interplanetary transport with Starship,” says Sepanloo. Oh, and don’t forget t...

In the monolithic applications SpaceX used at the time, some applications were on a homegrown JavaScript framework and other applications started moving to KnockoutJS. “In 2014, we started building a new architecture. Fun fact, our old solution was called DS9, and this new approach was called TNG, because our team loved Star Trek,” says Madonia with a laugh. The team began using AngularJS and considering the idea of microservices. “One problem with a monolith is that you have to deploy all of...

Steven Sepanloo, a Software Engineering Manager on the team, ran us through their software stack and how it’s shifted over the four and half years he’s worked at SpaceX. “It’s been evolutionary and not revolutionary until recently. Four years ago, we had AngularJS, C#, and an MSSQL relational backend, which was a very standard transactional stack for a single-page web application. Those applications still exist, but we’ve moved over to using Angular for newer applications.” The team has also ...

From purchasing and receiving raw material, creating and executing work orders to build spacecraft, tracking quality escapes and change management, and implementing procedures to launch a rocket, the system needs to be robust enough to handle the manufacturing and launch of a Falcon 9. This rocket could be carrying cargo or humans to the International Space Station or delivering satellites to orbit; reliability is a top concern. “One example of our applications is a part management system tha...
