Kevin Gill ‘11G
InSight: RIVIER ACADEMIC JOURNAL, VOLUME 14, NUMBER 1, FALL 2018 EXPLORING THE UNIVERSE: Meet Kevin Gill ‘11G Michelle Marrone (From Rivier Today, Fall 2018) From the comfort of his lab chair in sunny, southern California, Kevin Gill ’11G has a view into outer space. As a Science Data Software Engineer at NASA’s Jet Propulsion Laboratory (JPL), he spends his time planning and designing technology in support of environmental science and space exploration, as well as data visualization and planetary imaging. His recent work not only produced the first-ever close views of Saturn, but also contributed to NASA’s team winning an Emmy Award. Kevin earned his M.S. in Computer Science at Rivier and has been designing software to render the unique images he gathers ever since. He used an algorithm he developed during his program at Rivier to generate hypothetical images portraying Mars as a vibrant planet with oceans, an oxygen-rich atmosphere, and a green biosphere. The images went viral and within a week his work was featured on major media networks—Discovery News, Fox News, Universe Today, and the Huffington Post. His work captured NASA’s attention and paved the way for his career move. “Rivier taught me many of the algorithms and development practices I still use today at NASA,” says Kevin. “In fact, I can trace the lineage of code currently running on NASA systems directly to my final master’s project at the University.” The systems and tools he develops support a range of scientists specializing in the areas of climate, oceanography, asteroids, planetary science, and others. -
PUTTING LIFE on MARS: Using Computer Graphics to Render a Living Mars
InSight: RIVIER ACADEMIC JOURNAL, VOLUME 9, NUMBER 1, SPRING 2013 PUTTING LIFE ON MARS: Using Computer Graphics to Render a Living Mars Kevin M. Gill ‘11G* Senior Software Engineer, Thunderhead.com, Manchester, NH Keywords: Computer Graphics, Mars, Life, Planetary Science, OpenGL Abstract This article describes the software, algorithms & decisions that went into the development of the Living Mars image project. This includes topics related to computer graphics, software development, astronomy, & planetary science. The purpose of the project was to create a visualization of the planet Mars as could look with a living biosphere. This makes no distinction as to whether this biosphere would represent an ancient or future, possibly terraformed planet. 1 Background Mars, named for the Roman god of war. Ancient civilizations have forever associated the planet with fear, war, and destruction. It is the color of blood, and “one of a handful of planets visible to the naked eye, and the only one of marked color, so the planet demanded attention (Pyle, 2012).” Ever since man has noticed it, there have been dreams and visions of life on Mars, from Giovanni Schiaparelli and Percival Lowell describing channels and canals to Robert A. Heinlein’s science fiction. Lowell, in particular famous for fantastic writings of Mars, asked “are physical forces alone at work there, or has evolution begotten something more complex, something not unakin to what we know on Earth as life?” (Lowell, 1895) Even more recent discoveries by NASA’s Curiosity rover have found proof that liquid water once flowed billions of years ago positing an environment that could have served host to life (Brown, 2013). -

Appendix I Lunar and Martian Nomenclature
APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject. For further references see: [AU Trans. X, 259-263, 1960; XIB, 236-238, 1962; Xlffi, 203-204, 1966; xnffi, 99-105, 1968; XIVB, 63, 129, 139, 1971; Space Sci. Rev. 12, 136-186, 1971. Because at the recent General Assemblies some small changes, or corrections, were made, the complete list of Lunar and Martian Topographic Features is published here.

Emended Descriptions of Genera of the Family Halobacteriaceae

In recent years, many novel species have been added to the established genera but, in many cases, one or more properties of the novel species do not agree with the published descriptions of the genera. Authors have often failed to provide emended genus descriptions when necessary. Following discussions of the International Committee on Systematics of Prokaryotes Subcommittee on the Taxonomy of Halobacteriaceae, we here propose emended descriptions of the genera Halobacterium, Haloarcula, Halococcus, Haloferax, Halorubrum, Haloterrigena, Natrialba, Halobiforma and Natronorubrum. The family Halobacteriaceae was established by Gibbons rRNA gene sequence-based phylogenetic trees rather than (1974) to accommodate the genera Halobacterium and on true polyphasic taxonomy such as recommended for the Halococcus. At the time of writing (September 2008), the family (Oren et al., 1997). As a result, there are often few, if family contained 96 species whose names have been validly any, phenotypic properties that enable the discrimination published, classified in 27 genera. -
