The company was founded in 2002 to revolutionize space technology, with the ultimate goal of enabling people to live on other planets. What fault-tolerant measures were taken (when such a large underlying codebase powers it) and what efforts went into rad hardening? We recommend using r/SpaceX with Old Reddit. Given the significant importance of reliable software, the team leverages extensive approaches to testing. - Jeff, Yes, the entire software team took feedback from Bob and Doug on all aspects of the software. For starters, we designed the system to use end-to-end encryption for our users' data, to make breaking into a satellite or gateway less useful to an attacker who wants to intercept communications. Falcon 9, Grasshopper, and Dragon applications; and do the core What does the development cycle for flight simulators look like (for the Falcon systems, say)? ), but it's something we take very seriously. - Jeff, Contingency comes in many forms in our software.

The company has more than 3,000 of these partners, with 1,100 of them making weekly deliveries. I brought 50 key members of the Air Force software team to SpaceX to see how they build rockets and software. ), instead of refactoring existing code? You will be responsible for managing a team of six software engineers, developing highly reliable software systems, and keeping the standards of practice up to date. Control to support active missions. Different subsystems are generally isolated from each other, sometimes in the same computer, sometimes across different computers, with narrow interfaces between them. You will be responsible for managing a team of six software engineers, developing highly reliable software systems, and keeping the standards of practice up to date. They all run in time synchronization with each other, and the flight computer oversees all actions. Is the software composed of small (sometimes independent) modules, or is everything integrated in one big module? We have a distinct team in Flight Reliability whose main job is to calculate these numbers and ensure its kept up to date given various hardware and conops changes. https://www.coderskitchen.com/spacex-software-development-and-testing Matt Monson, who leads Starlink software team at SpaceX, has revealed that each batch of 60 Starlink satellites carries more than 4000 Linux computers … We can deploy a test build to a small subset of our vehicles, and then compare how it performs against the rest of the fleet. Building test cases we can run on the ground is a great way to answer these questions, and we do a lot of that, but it's not the only way.
