Open-source space software · SPX
The planets, the stars and the Earth for the web, drawn from the numbers of NASA, JPL and the IAU, checked against them, and free to use under the MIT licence.
Ready today
Each one is an npm package with a live demo, an embed page you can drop into any site, and guides in English and Japanese.
The solar system
The Sun, the planets, the dwarf planets and their moons, as clean line drawings, a shaded 3D look or NASA surface maps, at their real sizes and tilts.
npm i @johnmorrisdotca/wakusei-planets
The stars
The stars you can see, and the Sun's neighbours, as data and as sky charts you can turn, zoom and search.
npm i @johnmorrisdotca/hoshi-stars
The Earth
A globe for the web: country outlines, day and night, city lights and clouds, centred on where you are, with satellites on their real orbits.
npm i @johnmorrisdotca/chikyu-earth
In development
We are building a game where you design rockets from real parts and fly them on real orbits, through the same solar system the packages above describe: true positions, true distances, true moons.
The rockets are open source already, so you can use them in your own work today.
Line drawings and 3D views of real rockets, every variant with sourced sizes. Assemble a rocket from parts, stack it and separate the stages.
Built on public science
Each package credits its sources in its NOTICE file and documents how accurate it is and how that was tested.
Who makes it
Space Program X is made by John Morris. For now the packages are published from his own GitHub account and npm scope, johnmorrisdotca, and they will stay free and open source.
