Such endeavors not only contribute to broader scientific understanding but also train the next generation of researchers in mission design and execution.
Mission Subject and Science Objectives
The AtmoProbe Balloon Mission centers on examining the stratosphere’s response to climate change, with a particular emphasis on ozone layer dynamics and atmospheric mixing processes. The primary science goals involve measuring variations in key atmospheric parameters to assess how increasing greenhouse gas concentrations influence stratospheric stability (Smith et al., 2020). For instance, the mission seeks to quantify ozone depletion rates at mid-latitudes, which are critical for understanding ultraviolet radiation exposure on Earth’s surface. Additionally, objectives include analyzing temperature inversions and humidity profiles to model potential feedback loops in global warming scenarios.
These goals are grounded in current research highlighting the stratosphere’s role in climate regulation. As noted by Thompson (2019), stratospheric ozone acts as a barrier against harmful solar radiation, and its depletion could exacerbate surface temperature rises. By targeting these aspects, the mission addresses gaps in data from ground-based observations, providing high-resolution insights that complement satellite missions like those from NASA’s Aura satellite. Overall, the project aims to generate empirical evidence supporting refined climate models, fostering a deeper comprehension of atmospheric interconnectedness.
Mission Platform
The selected platform for this mission is a zero-pressure scientific balloon, operated under NASA Wallops Flight Facility’s balloon program. This choice is optimal due to its ability to achieve sustained flights at stratospheric altitudes, typically between 30 and 40 kilometers, without the need for propulsion systems (NASA, 2022). Unlike sounding rockets, which offer brief exposure times, balloons provide extended data collection periods, making them ideal for continuous atmospheric sampling. Wallops’ expertise in balloon launches, with over 1,700 successful flights since the 1960s, ensures reliable support and integration.
Furthermore, the platform’s cost-effectiveness and minimal environmental impact align with the mission’s constraints. Balloons can carry payloads up to 3,600 kilograms, accommodating the necessary instrumentation while allowing for recovery and reuse. This selection enhances the mission’s feasibility, as Wallops provides launch infrastructure, tracking, and telemetry services, minimizing risks associated with alternative platforms like aircraft or drones.
Mission Elements
Data collection will focus on temperature, pressure, radiation levels, ozone concentration, and humidity, gathered using specialized instrumentation. A radiosonde will measure temperature and pressure profiles, while an ozonesonde will detect ozone partial pressures via electrochemical reactions (Thompson, 2019). Additionally, a ultraviolet spectrometer will assess radiation flux, and a hygrometer will track water vapor content. These instruments, inspired by those discussed in NASA’s balloon technology modules, ensure accurate, real-time data acquisition.
Collection occurs at altitudes from 10 to 40 kilometers, targeting the troposphere-stratosphere transition where key dynamics unfold. Regarding biological elements, the mission incorporates a controlled experiment with up to 10 African clawed frogs (Xenopus laevis) in a sealed habitat module to study microgravity effects on amphibian physiology, though this is secondary. These frogs, known for resilience in variable environments, could survive the 24-hour duration with life support systems maintaining stable conditions (Smith et al., 2020). The integration of such elements demonstrates the platform’s versatility for multi-disciplinary research.
Research Team
The research team comprises undergraduate and postgraduate students from the University of Manchester’s Department of Aeronautics, collaborating with faculty advisors and NASA liaisons. As a university-led initiative, the group draws on academic resources, including simulation labs and data analysis tools, to develop the proposal. This structure promotes educational growth while ensuring alignment with Wallops’ guidelines for student projects.
Mission Duration
Planning for the mission is estimated at six months, involving design refinement, payload assembly, and safety reviews. Launch is targeted for September 2024, capitalizing on favorable weather at Wallops. Data collection will span 1,440 minutes (24 hours) during ascent, float, and descent phases, with telemetry providing continuous monitoring.

Mission Constraints
Several limiting factors shape the mission, including time, size, and instrumentation availability. Flight duration is capped at 24 hours due to balloon design and FAA regulations on airspace usage, restricting data volume (NASA, 2022). Payload size is limited to 100 kilograms to maintain buoyancy, constraining instrument complexity. Availability of specialized sensors, such as ozonesondes, depends on supply chains, potentially delaying timelines. Environmental constraints, like wind patterns at Wallops, may necessitate launch windows, while budget limitations cap funding requests at $500,000, as per similar projects (Thompson, 2019).
Mission Stakeholders
This research investigates stratospheric changes driven by climate factors, yielding data on ozone and temperature that benefits stakeholders such as NASA scientists for model validation, government agencies like the UK Environment Agency for policy formulation, and the public through improved climate predictions. Industry partners in aerospace could apply findings to satellite technologies, while international collaborators, including the European Space Agency, gain insights for joint missions. Ultimately, the public benefits from enhanced environmental awareness and potential advancements in weather forecasting accuracy.
