University of Florida Thesis Or Dissertation Formatting DELAY TOLERANT NETWORKING FOR CUBESAT TOPOLOGIES AND PLATFORMS By PAUL MURI A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA 2013 1 © 2013 Paul Muri 2 To my beloved parents, Theresa Muri and David Muri; and to my colleagues, friends, and family who believe in me 3 ACKNOWLEDGMENTS I would like to express my sincerest gratitude to my academic advisor, Prof. Janise McNair, for her invaluable guidance and continuous support throughout my undergrad and graduate studies at the University of Florida. Her openness and encouragement of my ideas helped me become a better researcher. Without her excellent advice, patience, and support, this doctoral dissertation would not be possible. I would like to thank all of my committee members, Prof. Jenshan Lin, Prof. Jasmeet Judge, and Prof. Norman Fitz-Coy, for serving on my committee. The committee’s valuable comments and constructive criticism helped to improve this dissertation greatly. I also would like extend my appreciation to the Wireless and Mobile System laboratory colleagues. They always gave me valuable suggestions, generous support, and fruitful “jam sessions” during my graduate studies at the University of Florida. I thank all of my labmates, Gokul Bhat, Obul Challa, Max Xiang Mao, Sherry Xiaoyuan Li, Jing Qin, Jose Alomodovar, Krishna Chaitanya, Dante Buckley, Ritwik Dubey, Bom Leenhapat Navaravong, Dexiang Wang, Jing Jing Pan, Gustavo Vejarano, Seshupriya Alluru, Eric Graves, and Corey Baker, in no particular order. All of them made my days in the lab more enjoyable. This work was supported by a NASA Office of the Chief Technologist’s Space Technology Research Fellowship (NSTRF) grant number NNX11AM73H. I would like to thank Dave Israel, Tom Flatley, Gary Crum, Jane Marquart, Greg Menke, and Faith Davis at NASA Goddard Space Flight Center for providing equipment and expertise. 4 The work from Chapter 3, and Chapter 4 was partially supported by IRAD grants from Lockheed Martin's Information Systems & Global Services (LM IS&GS) group, and the Advance Space Technologies Research & Engineering Center (ASTREC). This work was also partially supported in part by the National Science Foundation (ECCS-0901706). Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation. Last, I would like to thank my parents, Theresa Simpson Muri and David Muri, for their love, support, and sacrifice.

HaneVEER MSc Thesis Aerospace Engineering Orbital lifetime predictions An assessment of model-based ballistic coecient estimations and adjustment for temporal drag coecient variations by M.R. Haneveer to obtain the degree of Master of Science at the Delft University of Technology, to be defended publicly on Thursday June 1, 2017 at 14:00 PM. Student number: 4077334 Project duration: September 1, 2016 – June 1, 2017 Thesis committee: Dr. ir. E. N. Doornbos, TU Delft, supervisor Dr. ir. E. J. O. Schrama, TU Delft ir. K. J. Cowan MBA TU Delft An electronic version of this thesis is available at http://repository.tudelft.nl/. Summary Objects in Low Earth Orbit (LEO) experience low levels of drag due to the interaction with the outer layers of Earth’s atmosphere. The atmospheric drag reduces the velocity of the object, resulting in a gradual decrease in altitude. With each decayed kilometer the object enters denser portions of the atmosphere accelerating the orbit decay until eventually the object cannot sustain a stable orbit anymore and either crashes onto Earth’s surface or burns up in its atmosphere. The capability of predicting the time an object stays in orbit, whether that object is space junk or a satellite, allows for an estimate of its orbital lifetime - an estimate satellite op- erators work with to schedule science missions and commercial services, as well as use to prove compliance with international agreements stating no passively controlled object is to orbit in LEO longer than 25 years.

    SSC17-X-02 Breaking (Space) Barriers for 50 Years: The Past, Present, and Future of the DoD Space Test Program Barbara Manganis Braun, Sam Myers Sims, James McLeroy The Aerospace Corporation 2155 Louisiana Blvd NE, Suite 5000, Albuquerque, NM 87110-5425; 505-846-8413 [email protected] Colonel Ben Brining USAF SMC/ADS 3548 Aberdeen Ave SE, Kirtland AFB NM 87117-5776; 505-846-8812 [email protected] ABSTRACT 2017 marks the 50th anniversary of the Department of Defense Space Test Program’s (STP) first launch. STP’s predecessor, the Space Experiments Support Program (SESP), launched its first mission in June of 1967; it used a Thor Burner II to launch an Army and a Navy satellite carrying geodesy and aurora experiments. The SESP was renamed to the Space Test Program in July 1971, and has flown over 568 experiments on over 251 missions to date. Today the STP is managed under the Air Force’s Space and Missile Systems Center (SMC) Advanced Systems and Development Directorate (SMC/AD), and continues to provide access to space for DoD-sponsored research and development missions. It relies heavily on small satellites, small launch vehicles, and innovative approaches to space access to perform its mission. INTRODUCTION Today STP continues to provide access to space for DoD-sponsored research and development missions, Since space first became a viable theater of operations relying heavily on small satellites, small launch for the Department of Defense (DoD), space technologies have developed at a rapid rate. Yet while vehicles, and innovative approaches to space access.

  • FASTSAT a Mini-Satellite Mission…..A Way Ahead”
    Proposed Abstract: Under the combined Category and Title: “FASTSAT a Mini-Satellite Mission…..A Way Ahead” Authors: Mark E. Boudreaux, Joseph Casas, Timothy A. Smith The Fast Affordable Science and Technology Spacecraft (FASTSAT) is a mini-satellite weighing less than 150 kg. FASTSAT was developed as government-industry collaborative research and development flight project targeting rapid access to space to provide an alternative, low cost platform for a variety of scientific, research, and technology payloads. The initial spacecraft was designed to carry six instruments and launch as a secondary “rideshare” payload. This design approach greatly reduced overall mission costs while maximizing the on-board payload accommodations. FASTSAT was designed from the ground up to meet a challenging short schedule using modular components with a flexible, configurable layout to enable a broad range of payloads at a lower cost and shorter timeline than scaling down a more complex spacecraft. The integrated spacecraft along with its payloads were readied for launch 15 months from authority to proceed. As an ESPA-class spacecraft, FASTSAT is compatible with many different launch vehicles, including Minotaur I, Minotaur IV, Delta IV, Atlas V, Pegasus, Falcon 1/1e, and Falcon 9. These vehicles offer an array of options for launch sites and provide for a variety of rideshare possibilities.

The O/OREOS (Organism/Organic Exposure to Orbital Stresses) nanosatellite is the first science demonstration spacecraft and flight mission of the NASA Astrobiology Small- Payloads Program (ASP). O/OREOS was launched successfully on November 19, 2010, to a high-inclination (72°), 650-km Earth orbit aboard a US Air Force Minotaur IV rocket from Kodiak, Alaska. O/OREOS consists of 3 conjoined cubesat (each 1000 cm3) modules: (i) a control bus, (ii) the Space Environment Survivability of Living Organisms (SESLO) experiment, and (iii) the Space Environment Viability of Organics (SEVO) experiment. Among the innovative aspects of the O/OREOS mission are a real-time analysis of the photostability of organics and biomarkers and the collection of data on the survival and metabolic activity for micro-organisms at 3 times during the 6-month mission.
