Introduction
Gordon Gartrelle earned his PhD in Aerospace Science - Planetary Science at the University of North Dakota in December, 2019. Gordon does research in Asteroid Spectroscopy, Icy Outer Solar System bodies, Remote Sensing, and Astrobiology He is currently focused on the spectral variations of D-type asteroids, their surface geochemical properties, and potential ties to terrestrial meteorites.

Asteroids are the origin point for most meteorites impacting Earth. Terrestrial meteorite samples provide evidence of what actually occurred in the early solar system at the formation location of the meteorite, and when it occurred. The ability to connect a meteorite sample to an asteroid parent body provides its starting location as a meteoroid. T...
D-type asteroids represent a complex mystery related to the accretional history, composition, and dynamical migration of Outer Solar System objects. These spectrally featureless bodies have revealed few clues while raising many questions over four decades. D-types are dark, difficult to observe and perhaps contain unaltered primordial material. D-t...
D-type asteroids are a prime example of the many dark, low-albedo asteroids which do not reflect sufficient light to reveal detectable mineral absorptions. While D-type asteroids are relatively rare in the inner solar system and the main asteroid belt, they are dominant among the Jovian Trojans. In this study, we have applied Shkuratov radiative tr...
The definitive discovery of another form of life from beyond Earth will answer one of our most fundamental questions: Are we alone in the Universe? This announcement will be the most significant in history. It will have impact on every facet of our lives and affect everyone on Earth. Ensuring the announcement is handled properly represents an oppor...

Lightcurve study of the asteroid 846 Lipperta indicates a very long rotation period, most likely P = 1641 ± 23 h, and a lightcurve amplitude of 0.3 mag during the apparition of 2010-2011. This makes it one of the slower rotators with well-determined lightcurve parameters.
