Blue Marble in Tableau

Before the awe-inspiring photograph of the Pale Blue Dot, and the more recent image of an evening “star” in the Martian sky, the crew of Apollo 17 captured our home world in The Blue Marble (AS17-148-22727). Possibly the most reproduced photograph in human history, this piece of “viz art” I created using Tableau Public adds... Continue Reading →


Exospheric Effects of Lunar Industrialization

The Moon has an impermanent hold on its tenuous atmosphere. Its relatively weak gravity (1.62 m s-2), one sixth of Earth’s, struggles to hold onto the gas species that do exist in its exosphere environment. Though the Moon readily contributes gasses to its exosphere, external forces strip these away into a streaming tail. Fine dust... Continue Reading →

Spacecraft Habitable Volumes, Mission Duration

Currently reading Out of this World: The New Field of Space Architecture by A. Scott Howe and Brent Sherwood and wanted to reproduce a chart that they made: I included more instances of historic inhabited spacecraft than the original chart (above), as well as inhabited spacecraft that were docked to each other, combining their habitable...

3D Print Martian Moons

Download these STL files for Phobos and Deimos and 3D print your own Martian moons! Point cloud shape model of the largest of Mars' two moons, Phobos. This was made using data from the NASA Planetary Data System, plotted using R and the rgl library. (see my code here on Github) The enveloping red sphere... Continue Reading →

Lights, Water, Elections

What do watersheds, urban light pollution, and the 2012 presidential election have to do with each other? I don't know, but I made a map. I've combined these three disparate geospatial data layers to produce the image below of the lower 48 states (sorry Alaska, Hawaii, Puerto Rico, Guam, and other territories/insular areas of the...

Visualization of Solar System Objects

This interactive visualization was created using Tableau. All known objects with a radius greater than 400 km are represented along a logarithmic scale of their orbital semi-major axis (heliocentric distance in AU). The slider at the bottom allows you to select a range of heliocentric distances to zoom in on. Hovering your mouse cursor over... Continue Reading →

Lunar Artifacts Map

I created this map using Tableau several years ago to practice using the software. The data came from the "Catalogue of Manmade Material on the Moon" (pdf) compiled by NASA's History Program Office.
