Space Solar Power As An Enabler For A Human Mission To Mars, Corey Bergsrud, Jeremy Straub

Jeremy Straub

Space Solar Power (SSP), a technology based on the collection and aggregated transmission of light from the sun, offers an opportunity to create a deep space electrical infrastructure in order to provide the required level of power to a prospective Mars settlement. Several approaches to this challenge are presented and compared. Under the first approach, several Solar Powered Satellites (SPSs) are positioned in space between the Earth and Mars. These SPSs will capture large amounts of solar energy and transmit this energy in a focused beam via laser or microwave to relay SPSs until the energy finally reaches its Mars …

Space Solar Power Satellite Systems As A Service Provider Of Electrical Power To Lunar Industries, Corey Bergsrud, Jeremy Straub, James Casler, Sima Noghanian

Jeremy Straub

Space Solar Power (SSP) systems are poised to deliver significant benefits on Earth and elsewhere. SSP systems are based on the concept of collecting large amounts of solar energy in space and relaying the energy, in the form of microwave or laser radiation, to a receiving array that converts the transmitted energy into usable energy at the destination. An increase in space enterprise dictates the requirement for a continuous supply of energy in order to maintain human-supporting and robotic operation. SSP systems can form a part of the solution to this need. They can be utilized as a service provider …

Enabling Interplanetary Small Spacecraft Science Missions With Model Based Data Analysis, Jeremy Straub

Jeremy Straub

Small spacecraft operating outside of Earth orbit are significantly constrained by the communica- tions link available to them. This is particularly true for stand-alone craft that must rely on their own antenna and transmission systems (for which gain and available power generation are limited by form factor); it is also applicable to ‘hitchhiker’-style missions which may be able to utilize (quite likely very limited amounts of) time on the primary spacecraft’s communications equip- ment for long-haul transmission.

This poster presents the adaptation of the Model-Based Transmission Reduction (MBTR) frame- work’s Model-Based Data Analysis (MBDA) component for use on an interplanetary …

Open Beyond Orbit: Using The Designs From The Open Prototype For Educational Nanosats Outside Of Earth Orbit, Jeremy Straub

Jeremy Straub

This paper presents an overview of the Open Prototype for Educational NanoSats (OPEN) and its prospective use in interplanetary missions. OPEN is framework to facilitate the low-cost creation of CubeSat-class spacecraft via using publically available (provided by the OPEN project) de- signs, software, fabrication instructions and test plans. The base open configuration is designed to be able to be produced with a parts budget of under $5,000. Despite this low cost, it is a very ro- bust spacecraft (with capabilities meeting or exceeding many of the vendor-kit solutions which cost eight-or-more times this amount).

Two approaches for using the OPEN …

Design, Fabrication, And Testing Of An Emr Based Orbital Debris Impact Testing Platform, Jeffrey J. Maniglia Jr.

Master's Theses

This paper describes the changes made from Cal Poly’s initial railgun system, the Mk. 1 railgun, to the Mk. 1.1 system, as well as the design, fabrication, and testing of a newer and larger Mk. 2 railgun system. The Mk. 1.1 system is developed as a more efficient alteration of the original Mk. 1 system, but is found to be defective due to hardware deficiencies and failure, as well as unforeseen efficiency losses. A Mk. 2 system is developed and built around donated hardware from the Naval Postgraduate School. The Mk. 2 system strove to implement an efficient, augmented, electromagnetic …

Feasibility Of Microsatellite Active Debris Removal Systems, Karsten J. James

Master's Theses

Space debris has become an increasingly hazardous obstacle to continued spaceflight operations. In an effort to mitigate this problem an investigation of the feasibility of a microsatellite active debris removal system was conducted. Through proposing a novel concept of operation, utilizing a grapple-and-tug system architecture, and by analyzing each resultant mission phase in the frame of a representative example, it was found that microsatellite scale systems are capable of fulfilling the active debris removal mission. Analysis of rendezvous, docking, control and deorbit mission requirements determined that the design of a grapple-and-tug system will be driven by sizing of the propellant …

Open And Openorbiter: A Needs-Responsive Solution For The Small Satellite Community, Jeremy Straub, Atif Mohammad

Jeremy Straub

The Open Prototype for Educational NanoSats (OPEN) is an initiative launched at the University of North Dakota, as a public service to the nation and the world. The OPEN team is working to create a design, set of implementation instructions and a testing plan for a 1-U CubeSat (which can also serve as a basis for a 2-U or 3-U CubeSat with limited modifications). These will be made publically available to facilitate the low-cost implementation of CubeSat programs at other institutions. The target of the designs is to allow fabrication with a parts budget of approximately $5,000. This is, thus, …

The International Trafficking In Arms Regulations: Precluding Innovation In Academic Spacecraft Engineering — Or Are They?, Jeremy Straub, Joe Vacek

Jeremy Straub

Government regulations and uncertainty about their enforcement can be a significant barrier to innovation. In business, it is undesirable to consume time and other resources developing a product that cannot be sold or which requires navigating significant bureaucracy for each sale. In academ-ia, where limited funding is available prior to the submission of a grant pro-posal and receipt of an award, proposal-stage compliance costs can derail a project long before it begins. This paper reviews the International Traffick-ing in Arms Regulations (ITAR) and their impact on spacecraft research in academia, private research labs and industry. It reviews the exemptions available, …

Risk Analysis & Management In Student-Centered Spacecraft Development Projects, Jeremy Straub, Ronald Fevig, James Casler, Om Yadav

Jeremy Straub

Student involvement in any engineering project introduces an element of risk. This risk is particularly pronounced with small spacecraft projects, as a failure of the spacecraft on-orbit can result in a complete failure of the mission. However, student involvement in these projects is critical to allow research aims to be accomplished, in a university setting, and to train the next generation of spacecraft engineering professionals. The nature of risks posed by student involvement is discussed and a framework for assessing and mitigating these risks presented.
