Providing Effective Student Feedback: Effects Of Sociotropy, Student-Teacher Connectedness, And Expressed Disappointment And Praise On Students' Self-Esteem And Motivation, Emily Davied

All Graduate Theses and Dissertations, Fall 2023 to Present

This study examined how different types of teacher feedback (i.e., expressed pride, expressed disappointment, and near-neutral feedback) impact students’ motivation to learn and self-esteem. It also explored whether such effects vary depending on students' personality and how connected they feel to their teacher. Undergraduate students (N = 221) imagined receiving feedback from a teacher and completed surveys assessing their motivation, self-esteem, sociotropy, and connectedness with the teacher. The results showed that feedback expressing disappointment lowered students' self esteem compared to expressing pride and lowered students' motivation compared to near neutral feedback. Although sociotropy (i.e., dependence on others' approval) and teacher …

Balancing Root-Zone Oxygenation And Rhizosphere Stability: The Impact Of Aeration And Hypoxia On Hydroponic Plant Growth, Christian D. Baker

All Graduate Theses and Dissertations, Fall 2023 to Present

As the global population and food demand continue to increase, growers must look to innovative and sustainable methods for plant cultivation. Hydroponics is a popular method of sustainable plant cultivation where plant roots are suspended over a liquid nutrient solution. Hydroponics uses less water compared to traditional agriculture because there is no evaporation or solution runoff. It also maximizes land use, requires fewer pesticides and herbicides, and enables year-round cultivation in controlled environments. However, indoor hydroponic systems rely on artificial lighting, which has higher energy costs than traditional farming methods. Optimizing growing conditions is therefore critical to ensure long-term economic …

Design, Qualification, And Implementation Of Modular Spacecraft Radio Testing Enclosures For Small Satellite Missions, Dexter Stewart

Small Satellite Conference

As small satellite missions evolve, spacecraft platforms increasingly integrate radio-frequency (RF) antennas to support telemetry, command, and inter-satellite communication links that must be verified following full system integration. Recent changes in launch site safety policy, most notably SpaceX’s ban on over-the-air (OTA) testing, have created a critical gap in the ability to qualify spacecraft communication systems during testing at the launch site. This paper presents the design, qualification, and implementation of modular RF containment enclosures, known as ’antenna hats’, developed to enable safe, non-OTA testing of fully integrated small satellites. The antenna hats are self-contained enclosures that interface directly with …

Shining A Spotlight On Maritime Dark Traffic, Alex Da Silva Curiel, Darren Jones, Rob Knight, Rupert Taylor, Leo Jofeh, Sir Martin Sweeting, Per Atle Våland, Simon Flack, Patrik Mandelin, Håkon Heier

Small Satellite Conference

The ability to support Maritime Domain Awareness from space using Synthetic Aperture Radar (SAR) has been successfully demonstrated in the past, however practical challenges in achieving the necessary area coverage, temporal coverage and spatial resolution for a practical system has eluded wider adoption. Yet demand for Maritime Surveillance has increased in recent years, to protect important maritime energy and communications infrastructure, fisheries, and maritime reserves, and especially for maintaining national security and territorial integrity. A novel approach to the SAR payload design solves these challenges, and smallsat technologies have also matured to the point where a High-Resolution Wide-Swath (HRWS) system …

Development Of A Design Tool For 3d-Printable Cold Gas Thruster Systems For Nanosatellite Missions, Mikolaj Szyszka, Katherine Smith

Small Satellite Conference

Currently, there are 5219 Nanosatellites and CubeSats in orbit [1]. A decade ago, this number was only 800 [1], with forecasts predicting a total of 14,000 small satellites in orbit by 2033 [2]. However, out of the ones that are currently operational, only about 5% are equipped with a propulsion system. Omitting the electric and classified thrusters, cold gas systems are the most popular due to their simplicity and ease of operation. This shows a general lack of manoeuvrability and agility within small satellites in orbit. The proposed C.O.N.E tool aims to bridge the gap between nanosatellite manufacturers and simple …

Design And Validation Of A Modular Cubesat Framework For In-Space Assembly, Michael Kuhl, Jonah Goldstein, Kerri Cahoy

The Orbital Locker (ORLO) project at the Massachusetts Institute of Technology explores this shift in space operations with a prototype-scale demonstration. Standardized satellite sub-U modules are stored within a free-flying mothercraft and assembled on demand by an onboard Cartesian gantry robot, which electrically and mechanically mates the modules into complete 1U and 2U CubeSats as a prototype-scale demonstration. Once assembled, the CubeSat is electrically verified and deployed from the mothercraft into its target orbit.

The ORLO prototype integrates a locker frame, Cartesian gantry robot, …

I Think I'M Falling For You: Xvi Mission's Final Days In Orbit, Lee Jasper, Erika A. Chavez, Andrew A. Knuth, Adam T. Reinelt, Cameron Shideler, Jayce Thedford, Declan Byrne, Michael Dompke

Small Satellite Conference

The Air Force Research Lab’s (AFRL) Small Satellite Portfolio (SSP) created the XVI CubeSat which was launched on SpaceX’s Transporter 8 in June of 2023. 

XVI remained operational from June 2023 until its deorbit on January 7, 2026. Throughout its lifetime, the team maintained the vehicle and used XVI for experimentation and training purposes. However, due to the sun's low activity around this time frame, and intentionally lowering the drag/cross sectional area of XVI on orbit, the spacecraft was able to stay in orbit for months beyond its initial predicted re-entry. 

Between January 4th and January 7th, XVI was tracked …
