Space Apps Challenge 2017

EXPLANATION

Shadowfax allows the public to interact with eighteen satellite missions and three instruments that are aboard the International Space Station (ISS). These spacecraft missions and instruments are current NASA missions which are focused on Earth observation.

This web based application obtains the most recent Two Line Element (TLE) data from NORAD to propagate the orbits of the satellites and the ISS around the earth using the SGP4 propagator. Shadowfax allows the public to select one, multiple or all the spacecrafts as well as the duration the propagation.

The application also displays a projection of the Earth sensing instruments ground track for select sensors aboard the satellites and the ISS. This allows for the visualization of satellite sensor co-location.

Also available are various viewpoints from which to view the spacecraft motions. These viewpoints include a 3-D globe view, 2-D map view, and spacecraft jockey view (view of the spacecraft) all with panning and zoom capabilities.

Please keep your arms and legs inside the vehicle at all times.
