Astronomy has been an inherently visual area of science for millenia, yet a majority of its significant discoveries take place in wavelengths beyond human vision. There are many people, including those with low or no vision, who cannot participate fully in such discoveries if visual media is the primary communication mechanism. Numerous efforts have worked to address equity of accessibility to such knowledge sharing, such as through the creation of three dimensional (3D) printed data sets. This paper describes progress made through technological and programmatic developments in tactile 3D models using the NASA Chandra X-ray Observatory to improve access to data.
