REQUEST FOR SABBATICAL LEAVE. I am requesting a 100% sabbatical leave for the 2019-2020 academic year. Employed as a fulltime faculty member at Cerritos College since August 2005, I have never requested sabbatical leave during the past thirteen years of service. II. PURPOSE OF LEAVE Scientific advancements and technological capabilities, most notably within the last few decades, have evolved at ever-accelerating rates. Artists, like everyone else, now live in a contemporary world completely restructured by recent phenomena such as satellite imagery, augmented reality, digital surveillance, mass extinctions, artificial intelligence, prosthetic limbs, climate change, big data, genetic modification, drone warfare, biometrics, computer viruses, and social media (and that’s by no means meant to be an all-inclusive list).

Kostama, Astronomy, Department of Physics, P.O. Box 3000, FI-90014 University of Oulu, Finland ([email protected]). Introduction: Harmakhis Vallis is one of the four [e.g., 15–17]. Usually they have been excluded from major outflow channel systems that cut the eastern Hel- the crater counts because of the uncertainty of their las rim region of Mars (Fig. 1). It is ~800 km long and origin (primary vs. secondary crater). However, small located ~450 km south of Hadriaca Patera starting craters accumulate to the surface more quickly than close to the end of another valley, Reull Vallis. Due to larger ones, and thus the high spatial resolution is nec- the close position to the volcanic features, the channels essary in dating younger surfaces or small units where are suggested to have been formed by the mobilization there are only few large craters. In the case of Harma- and release of subsurface volatiles by volcanic heat [1– khis Vallis, the region has experienced significant re- 5]. Because Harmakhis Vallis cuts the surrounding cent modification and degradation, and thus, we can massifs of the cratered terrains, it is clearly one of the assume that the small crater population mostly post- youngest features in the region [6, 7]. dates the secondary craters forming larger impacts lo- cated in the older regions. Therefore, only the obvious clusters of secondary craters were excluded from the counts.

The origin of these objects is not known; while several have orbits that are stable on solar-system timescales, work by Rivkin et al. (2003) showed they have compositions that suggest separate origins from one another. We have obtained infrared (0.8-2.5 micron) spectroscopy of the two largest L5 Mars Trojans, and confirm and extend the results of Rivkin et al.

Introduction: While the surface of Mars may eralogy of deep impact craters was investigated using have had an active hydrosphere early in its history [1], TES, THEMIS, and CRISM data. it is likely that this water retreated to the subsurface Results: We identified ~40 craters of interest in the early on due to loss of the magnetic field and early northern hemisphere, the majority of which occur in atmosphere [2]. This likely resulted in the formation of western Arabia Terra – a potential upwelling zone of two distinct aqueous regimes for Mars from the Late interest [4].
