The document summarizes a project to create a system for sharing crowd-sourced asteroid imagery and visualizing asteroid data. The team developed a website with features to display asteroid imagery, plot the orbits of 4000 asteroids around the solar system by highlighting individual asteroids and showing planetary orbits. They used Node.js, Angular.js, and webGL for rendering. Due to time constraints, some planned features like 3D rendering and impact risk analysis had to be removed. All code was made open source.

What Challenge and Who? We attempted two challenges simultaneously. The main feature of our system was to enable the sharing of crowd-sourced asteroid imagery. We also visualised asteroid data. Our team is composed of Matthieu Rigolot, Leon Pegg, Elias Khoury, Derek Jones, Freddie Barr-Smith and Florian Rathgeber
Initial Project Scope We attempted to implement a solution to the challenges of asteroid imagery sharing and asteroid data visualisation. We also planned to implement asteroid impact risk analysis. Our initial plan was to enable users to share imagery related to different asteroids and also to visualise asteroid orbits.
Ethos of Project We have made all code produced during this event open source in order to enable others to work on our code or to use it for their own related projects. Our initial goals of displaying asteroid imagery and plotting asteroid data were achieved.
Revision of Initial Scope Due to the evolution of the software throughout the project, several initial goals had to be jettisoned, particularly impact risk analysis. Another feature that had to be jettisoned was our initial prototype for a unique 3d engine in webGL to render the earth and orbital trajectory of asteroids.
Design - Homepage The homepage is sleek, minimalist and responsive.
Design - Results
Design - Visualisation This is perhaps the most impressive part of the system, where 4000 asteroids are currently plotted in their orbits around the solar system.
Design - Visualisation The selected asteroid is highlighted with a red circle. Its individual orbit is also plotted with a white dashed line.
Design - Visualisation The orbital path of all planets are plotted in concentric coloured ellipses.
Implementation Frameworks Used We used node.js with jade templating and attempted to implement the MEAN stack We used angular.js We also used webGL to render the planetary objects and asteroids and the entirety of the visualisation. We used MongoDB also for temporary storage of data and for future caching purposes
Calculation of Orbits We calculated the orbit of individual asteroids from the data provided by asteranks API. First we attempted to calculate the orbital trajectory of an asteroid Finally we used a parametric equation which calculated the point that the asteroid is at along an ellipse
Calculation Of Orbits
Data Sources Used Asterank We used the API for asterank, which interfaces with the Minor Planet Centre Database and elements of their visualisation Jet Propulsion Laboratorys - Solar System Dynamics Small-Body Database Browser
Social Media Presence
Future Plans We would have liked to have implemented asteroid impact risk analysis. All code is available on github After the event we plan to improve and maintain the code We hope our tool will be used by astronomers worldwide
