Implications of Microorganisms in Future Crewed Missions to Mars
Crewed deep space missions will likely become a reality in the coming decades. One of the most challenging issues associated with Mars is the lack of resources for sustaining human life. Microbes can be used to help humans settle on Mars. However, they can also be problematic since terrestrial …

Assessing General Propulsion Architectures for Fast Transit Times to Mars for Crewed Missions
<p>As NASA and commercial contractors, such as SpaceX, continue to develop their programs with Artemis and Starship, respectively, it is becoming more and more apparent that the program developments are ultimately for finding a way to put humans onto Mars. However, when we approach the current …

Multiobjective optimization of crewed spacecraft supportability strategies
Future crewed missions present a logistical challenge that is unprecedented in human spaceflight. Astronauts will travel farther from Earth than ever before, and stay in space for longer, without access to regular resupply or the option to abort and return home quickly in the event of an emergency. …

A Network Communications Strategy for Planetary Habitats
… communications infrastructure that best supports crewed missions into the broader habitat design process. In doing so, this thesis intends to harmonize the disciplines of space architecture, network architecture, and systems design.

Off the Orbit: Works of Art for Long-Term Space Travellers. Outline of a novel artistic practice
… for display in works of art on extended crewed missions. The study claims that, within the research area of human spaceflight, novel working methods should be developed that can integrate the artist into the scientific process. The extraordinary challenges of extended space exploration …

Entry, descent and landing vehicle design space exploration for crewed Mars missions
… in 2004, NASA has been preparing plans for a crewed mission to Mars in the next few decades. One challenge associated with crewed missions to the Martian surface is the comparatively large mass of planned surface elements which will require an increase of at least an order of magnitude in the …

Skyflower: A Reusable Tethered Lunar Landing System
… address small-scale payload delivery or crewed missions. The current state of the art lacks dedicated solutions for high-mass, uncrewed cargo delivery—a critical gap for enabling infrastructure deployment, in-situ resource utilization, and sustained lunar operations. This thesis …

Small Spacecraft Design & Machine Learning-based Approaches To Lunar Robotics Navigation
… has benefited from a series of successful missions, including flybys, orbiters, landers (crewed and robotic), rovers, and impactors. The next generation of lunar exploration will include a cis-lunar station, crewed missions, and in-situ resource utilization (ISRU)-based missions that will …

Utilizing Permanent On-Board Water Storage for Efficient Deep Space Radiation Shielding
<p>As space technologies continue to develop rapidly, there is a common desire to launch astronauts beyond the ISS to return to the Moon and put human footsteps on Mars. One of the largest hurdles that still needs to be addressed is the protection of astronauts from the radiation environment seen …
