The Automation Of Analysis Procedures For The Citizen Cate Experiment Eclipse Data, Logan Jensen, Michael Pierce
Honors Theses AY 17/18
The Citizen Continental-America Telescopic Eclipse Experiment deployed 68 volunteer-operated telescope and camera systems across the United States to collect continuous data of the August 2017 solar eclipse. For any one location the eclipse lasted 2.5 minutes, but in total the nationwide CATE network collected data on the full 93 minutes of eclipse across America. The wealth of data collected contains more than 110,000 calibration and eclipse images and takes up 1.5 terabytes of memory. To become scientifically applicable, all these images needed to be corrected for systematic errors caused by the equipment and for human error. The ...
Education, Support, And Results For Wyoming Participants In The Citizen Cate (Continental-America Telescopic Eclipse) Experiment, Gabriel Miller
Honors Theses AY 17/18
Throughout the spring and summer of 2017, the Citizen CATE (Continental- America Telescopic Eclipse) Experiment was active in Wyoming and across the contiguous United States, with the goal of achieving an unbroken line of citizen- operated telescopes and cameras along the path of totality for the August eclipse. Eleven sites were active in Wyoming, composed of teachers, students, amateur and professional astronomers, and interested members of the community. In two large educational sessions, as well as several localized practice events, these groups were trained to use the telescopes and cameras provided for them. Working closely with the National Solar Observatory ...
An Investigation Into The Suitability Of Sulfate-Reducing Bacteria As Models For Martian Forward Contamination, 2018 University of Arkansas, Fayetteville
An Investigation Into The Suitability Of Sulfate-Reducing Bacteria As Models For Martian Forward Contamination, Maxwell M. W. Silver
Theses and Dissertations
The NASA Planetary Protection policy requires interplanetary space missions do not compromise the target body for a current or future scientific investigation and do not pose an unacceptable risk to Earth, including biologic materials. Robotic missions to Mars pose a risk to planetary protection in the forms of forward and reverse contamination. To reduce these risks, a firm understanding of microbial response to Mars conditions is required. Sulfate-reducing bacteria are prime candidates for potential forward contamination on Mars. Understanding the potential for forward-contamination of sulfate-reducers on Mars calls for the characterization of sulfate-reducers under Mars atmosphere, temperature, and sulfate-brines. This ...

Experimental Investigation Of A New Spiral Wingtip, 2018 International Islamic University - Malaysia
Experimental Investigation Of A New Spiral Wingtip, Naseeb Ahmed Siddiqui, Mohamed Aldeeb, Waqar Asrar, Erwin Sulaeman
International Journal of Aviation, Aeronautics, and Aerospace
Experiments on the relative merits and demerits of slotted wingtips mimicking a bird’s primary feathers have been performed. The real emargination length of feather tips, their flexibility and curved shapes during cruise are considered in the present study. The experiments were performed at a Reynolds number of 3.7 x 105 on a symmetric flat plate half wing of aspect ratio 3. Lift, drag and pitching moments were measured using a six component aerodynamic balance. Four different shapes inspired by bird primary feathers have been analysed. The rigid curved tip performed the best increasing the L/D ratio ...
The Earth's Magnetosphere, 2018 University of Montana
The Earth's Magnetosphere, Soren Ormseth
Undergraduate Theses and Professional Papers
The Interstellar Boundary Explorer (IBEX) is an Earth orbiting satellite launched in 2008; designed to map the boundary of our Solar System. In this presentation, we focus on how data collected by the IBEX-Hi sensor can be used to map the distribution of hot ions within the Earth's magnetosphere. As opposed to other satellites, IBEX images the magnetosphere from afar rather than by going through it. An improvement on the previous imaging techniques was developed, and we compare the new results to the old.
The Relationship Between The September 2017 Space Weather Event And The Crustal Magnetic Field Of Mars, Camella-Rosa C. Nasr
Undergraduate Honors Theses
In September 2017, the Imaging UltraViolet Spectrograph (IUVS) on the Mars Atmosphere and Volatile Evolution Mission (MAVEN) spacecraft detected a global aurora event that took place as a consequence of an unexpectedly strong blast from the sun. The most widespread of these detected auroras is diffuse aurora, which was confirmed to be global aurora. This global aurora was seen at lower altitudes and has been discovered to be directly related to the detection of highly energetic solar outbursts. These outbursts are typically energetic electrons precipitating downwards (Schneider et al., 2015). I was interested in learning more about the aurora that ...
Determining The Small-Scale Structure And Particle Properties In Saturn's Rings From Stellar And Radio Occultations, 2018 University of Central Florida
Determining The Small-Scale Structure And Particle Properties In Saturn's Rings From Stellar And Radio Occultations, Richard Jerousek
Electronic Theses and Dissertations
Saturn's rings consist of icy particles of various sizes ranging from millimeters to several meters. Particles may aggregate into ephemeral elongated clumps known as self-gravity wakes in regions where the surface mass density and epicyclic frequency give a Toomre critical wavelength which is much larger than the largest individual particles (Julian and Toomre 1966). Optical depth measurements at different wavelengths can be used to constrain the sizes of individual particles (Zebker et al. 1985, Marouf et al. 1983) while measurements of optical depths spanning many viewing geometries can be used to determine the properties of self-gravity wakes (Colwell et ...
Shape Modeling And Boulder Mapping Of Asteroid 1992 Uy4, 2017 Murray State University
Shape Modeling And Boulder Mapping Of Asteroid 1992 Uy4, Nicholas Duong
The structure and history of near-Earth asteroids are important to
study because they collide with Earth, sometimes with significant consequences for
climate and the survival of many species, including our own. If NASA is ever to deflect an asteroid on a collision course, it is crucial to know as much as possible about its size, composition, structure and boulder distribution. The boulder
distribution in turn helps to map the asteroid's gravitational field.
1992 UY4 is a near-Earth asteroid discovered in 1992. In August 2005, UY4 made a
``close" (for space) pass of Earth, about 15x farther than the Moon ...
Detection Of Survival And Proliferation Of Sulfate Reducers Under Simulated Martian Atmospheric And Soil Conditions, 2017 University of Arkansas, Fayetteville
Detection Of Survival And Proliferation Of Sulfate Reducers Under Simulated Martian Atmospheric And Soil Conditions, Sergio Mosquera Mora
Theses and Dissertations
Numerous studies have tried to determine the survivability and proliferation of microorganisms under simulated Martian conditions. Furthermore, most of them have been focused on the ability of these microbes to cope with high brines’ salt (NaCl) concentrations inherent of the Martian surface. However, there are not studies related to the ability of bacteria to survive on subsurface environments that have increasing concentrations of sulfate compounds. For this research, a group of microorganisms known as sulfate-reducing bacteria or simply sulfate reducers were chosen due to their ability to use sulfate compounds as terminal electron acceptors to produce metabolic energy, their tolerance ...

Facing The Sun, Frank Prendergast, Muiris O'Sullivan, Ken Williams, Gabriel Cooney
December 2017 marked 50 years since archaeologist Michael J. O’Kelly first observed the solar illumination of the burial chamber in the Neolithic passage tomb at Newgrange during the period of the winter solstice. O’Kelly subsequently recorded direct sunlight entering Newgrange through the ‘especially contrived slit which lies under the roof-box at the outer end of the passage roof’ on 21 December 1969. The discovery of this historic phenomenon, dating back over 5,000 years, captured the public interest and imagination at that time and ever since. In this major article published in the Winter 2017 edition of Archaeology ...
Physical Properties Of Faint Meteors Through High-Resolution Observations, 2017 The University of Western Ontario
Physical Properties Of Faint Meteors Through High-Resolution Observations, Dilini Subasinghe
Electronic Thesis and Dissertation Repository
Small, faint meteors (with masses between 10-7 and 10-4 kg) were once part of an asteroid or comet, and collide with Earth's atmosphere daily. Studying meteors is an effective way to survey the physical properties of their parent bodies. Meteor light curves and orbital information is easily obtained from wide-field observations, from which meteoroid structure can be inferred through meteoroid ablation modelling. A high-resolution narrow-field camera can provide much more detail about the poorly understood ablation processes and physical properties of the meteoroid. The goal of this thesis is to better understand the physical properties of meteors ...
Ion-Scale Wave Properties And Enhanced Ion Heating Across The Low-Latitude Boundary Layer During Kelvin-Helmholtz Instability, 2017 Embry-Riddle Aeronautical University
Ion-Scale Wave Properties And Enhanced Ion Heating Across The Low-Latitude Boundary Layer During Kelvin-Helmholtz Instability, T. W. Moore, K. Nykyri, A. P. Dimmock
In the Earth's magnetosphere, the magnetotail plasma sheet ions are much hotter than in the shocked solar wind. On the dawn sector, the cold-component ions are more abundant and hotter by 30–40% when compared to the dusk sector. Recent statistical studies of the flank magnetopause and magnetosheath have shown that the level of temperature asymmetry of the magnetosheath is unable to account for this, so additional physical mechanisms must be at play, either at the magnetopause or plasma sheet that contributes to this asymmetry. In this study, we perform a statistical analysis on the ion-scale wave properties in ...
Solar Eclipse Induced Atmospheric Turbulence Effects On High Altitude Balloons, 2017 University of North Dakota
Solar Eclipse Induced Atmospheric Turbulence Effects On High Altitude Balloons, Fnu Anamika, Denise Buckner, Peter Henson, Jennifer Fowler, Nanette Valentour
2017 Academic High Altitude Conference
The North Dakota Atmospheric Education Student Initiated Research (ND-AESIR) team launched a balloon during the total solar eclipse in Rexburg, Idaho. After the umbra’s passage, the balloon experienced unexpectedly high levels of atmospheric turbulence. Video footage taken from the payload displays the conditions, and analysis of flight path data models created from the iridium GPS confirm that unusually violent turbulence occurred. These forces caused the key rings holding the bottom of the parachute to the payload train to rip open; the balloon and parachute flew away and the payloads free fell to the surface from an altitude of 68 ...
Eclipse Ballooning Stem Outreach For Elementary, Middle, And High School Education, 2017 University of North Dakota
Eclipse Ballooning Stem Outreach For Elementary, Middle, And High School Education, Peter Henson, Fnu Anamika, Denise Buckner, Marissa Saad, Caitlin Nolby
2017 Academic High Altitude Conference
To promote Science, Technology, Engineering and Mathematics (STEM) education through ballooning, the North Dakota Space Grant Consortium (NDSGC) organizes an annual Near-Space Balloon Competition (NSBC) for students in grades 6 - 12. Students across the state of North Dakota have the opportunity to launch experiments into a near- space environment. The students learn how to write proposals, design payloads, and analyze data. They learn through an active, inquiry-based style that will prepare them for real-world engineering and critical thinking jobs. In 2016, NSBC proposed Great American Eclipse as the theme for the competition, thus the students were focused on designing heliocentric ...
On The Dawn-Dusk Asymmetry Of The Kelvin-Helmholtz Instability Between 2007 And 2013, 2017 Embry-Riddle Aeronautical University
On The Dawn-Dusk Asymmetry Of The Kelvin-Helmholtz Instability Between 2007 And 2013, Z. W. Henry, K. Nykyri, T. W. Moore, A. P. Dimmock, X. Ma
Using data from Time History of Events and Macroscale Interactions during Substorms (THEMIS), a statistical study was performed to determine whether a dawn-dusk asymmetry exists in the occurrence rates of the Kelvin-Helmholtz (KH) instability during Parker-Spiral (PS) and Ortho-Parker-Spiral (OPS) orientations of the interplanetary magnetic field (IMF). It is determined from the data that there is a strong preference toward the dawn side during PS orientation, and although a preference to the dusk side during OPS is suggested, this requires further study for an unambiguous confirmation. The uncertainty in the OPS result is due to a low number of events ...
Creating An Experimental Learning And Research Driven Spacesuit Lab For Erau, 2017 Embry-Riddle Aeronautical University
Creating An Experimental Learning And Research Driven Spacesuit Lab For Erau, Ryan L. Kobrick, Erik Seedhouse
Ryan L. Kobrick
This paper evaluates key functional data parameters that must be considered for suborbital spaceflight participants wearing pressurized suits for intravehicular activity (IVA). Data parameters of an analog spacesuit worn in an analog flight environment were obtained from 40 civilian participants using the Suborbital Space Flight Simulator (SSFS) at Embry-Riddle Aeronautical University (ERAU) while donning Final Frontier Design’s (FFD) fully pressurized third-generation spacesuit as part of their training for Project PoSSUM (the Polar Suborbital Science in the Upper Mesosphere Project). The physiological data collected included: blood pressure, electrocardiograms, heart rate, grip strength, and skin temperature. These parameters were measured using ...
Velocity-Dependent Inverse Cubic Force And Solar System Gravity Tests, 2017 Embry-Riddle Aeronautical University
Velocity-Dependent Inverse Cubic Force And Solar System Gravity Tests, Quentin G. Bailey, Daniel Havert
Higher mass dimension terms in an effective field theory framework for tests of spacetime symmetries are studied. Using a post-Newtonian expansion method, we derive the spacetime metric and the equations of motion for a binary system. This reveals an effective inverse cubic force correction to post-Newtonian general relativity that depends on the velocity of the bodies in the system. The results are studied in the context of laboratory and space-based tests including the effects on solar-system ephemeris, laser ranging observations, and gravimeter tests. This work reveals the coefficient combinations for mass dimension 5 operators controlling CPT violation for gravity that ...
Influence Of Velocity Fluctuations On The Kelvin-Helmholtz Instability And Its Associated Mass Transport, 2017 Embry-Riddle Aeronautical University
Influence Of Velocity Fluctuations On The Kelvin-Helmholtz Instability And Its Associated Mass Transport, Katariina Nykyri, Xuanye Ma, Andrew Dimmock, Claire Foullon, Antonius Otto, Adnane Osmane
Kelvin-Helmholtz instability (KHI) and associated magnetic reconnection and diffusion processes provide plasma transport from solar wind into the magnetosphere. The efficiency of this transport depends on the magnetosheath and magnetospheric plasma and field properties at the vicinity of the magnetopause. Our recent statistical study using data from the Time History of Events and Macroscale Interactions during Substorms spacecraft indicates that the amplitude of the magnetosheath velocity fluctuations perpendicular to the magnetopause can be substantial. We have performed a series of local macroscale 2.5-dimensional magnetohydrodynamic simulations of the KHI during strongly northward interplanetary magnetic field and with the initial plasma ...
