Wow, CartoDB is going to Mars? Well kind of. We're looking for an extra special intern that will help the European Space Agency search for a martian landing spot and communicate it to the public through an interactive web map visualization of the ExoMars Rover landing sites. The goal of this project is to design and build an engaging visualisation that facilitates the understanding of key concepts for selecting landing sites, including scientific and engineering constraints. The intern will work with the ESA's Planetary Science Archive Team and CartoDB team to design and prototype the front-end web interface and support the identification and preparation of geospatial data products.
