  • 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.

  • The Dynamics and Control of the Cubesail Mission — a Solar Sailing
    © 2010 Andrzej Pukniel. THE DYNAMICS AND CONTROL OF THE CUBESAIL MISSION—A SOLAR SAILING DEMONSTRATION BY ANDRZEJ PUKNIEL DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor in Philosophy in Aerospace Engineering in the Graduate College of the University of Illinois at Urbana-Champaign, 2010 Urbana, Illinois Doctoral Committee: Professor Victoria Coverstone, Chair Professor John Prussing Professor Rodney Burton Professor Gary Swenson ABSTRACT The proposed study addresses two issues related to the slow emergence of solar sailing as a viable space propulsion method. The low technology readiness level and complications related to stowage, deployment, and support of the sail structure are both addressed by combining the CU Aerospace and University of Illinois-developed UltraSail and CubeSat expertise to design a small-scale solar sail deployment and propulsion experiment in low Earth orbit. The study analyzes multiple aspects of the problem from initial sizing and packaging of the solar sail film into two CubeSat-class spacecraft, through on-orbit deployment dynamics, attitude control of large and flexible space structure, and predictions of performance and orbital maneuvering capability. ii ACKNOWLEDGEMENTS The following work would have not been possible without the continuous support and encouragement of my advisor, Professor Coverstone. Her patience, scientific insight, and enthusiasm are a rare combination that fosters a unique research environment. It allows the students to develop both as highly competent engineers as well as young individuals. Few advisors sincerely care for their students’ personal development as much as Professor Coverstone and I consider myself privileged to be part of her research group. I would also like to thank Professors Rod Burton and Gary Swenson as well as Dr.

Significa pues que muchos de ellos no han alcanzado el espacio y fueron destruidos. Se señala en primer lugar (a la izquierda) su nombre, seguido de la fecha del lanzamiento, el país al que pertenece el satélite (que puede ser otro distinto al que lo lanza) y el tipo de satélite; este último aspecto podría no corresponderse en exactitud dado que algunos son de finalidad múltiple. En los lanzamientos múltiples, cada satélite figura separado (salvo en los casos de fracaso, en que no llegan a separarse) pero naturalmente en la misma fecha y juntos.

IAC-15-D2.5.7x31069 IODINE PROPULSION ADVANTAGES FOR LOW COST MISSION APPLICATIONS AND THE IODINE SATELLITE (ISAT) TECHNOLOGY DEMONSTRATION John W. Dankanich NASA MSFC, USA, [email protected] Daniel M. Schumacher NASA MSFC, USA, [email protected] The NASA Marshall Space Flight Center Science and Technology Office is continuously exploring technology options to increase performance or reduce cost and risk to future NASA missions including science and exploration. Electric propulsion is a prevalent technology known to reduce mission costs by reduction in launch costs and spacecraft mass through increased post launch propulsion performance. The exploration of alternative propellants for electric propulsion continues to be of interest to the community. Iodine testing has demonstrated comparable performance to xenon. However, iodine has a higher storage density resulting in higher ∆V capability for volume constrained systems. Iodine’s unique properties also allow for unpressurized storage yet sublimation with minimal power requirements to produce required gas flow rates. These characteristics make iodine an ideal propellant for secondary spacecraft. A range of mission have been evaluated with a focus on low-cost applications. Results highlight the potential for significant cost reduction over state of the art. Based on the potential, NASA has been developing the iodine Satellite for a near-term iodine Hall propulsion technology demonstration. Mission applications and progress of the iodine Satellite project are presented. I. INTRODUCTION high density propellant alternatives, assessed The NASA Marshall Space Flight Center (MSFC) performance of the BHT-200 flight thruster operated on Science and Technology Office is continuously iodine and are maturing a 600W iodine Hall thruster assessing technology options to enhance or enable system.

Bilén Professor of Engineering Design, Electrical Engineering, and Aerospace Engineering Thesis Advisor Michael M. Micci Professor of Aerospace Engineering and Director of Graduate Studies George A. Lesieutre Professor of Aerospace Engineering Head of the Department of Aerospace Engineering *Signatures are on file in the Graduate School iii ABSTRACT CubeSats are small satellites that conform to combinations of a standard 10×10×10 cm form factor. Currently, CubeSats have limited propulsion options because their restrictive size. This thesis details the design and initial testing of a CubeSat-scale microwave electrothermal thruster. The goal of this research was to lay the groundwork for future thruster designs that could be incorporated into CubeSat propulsion modules. As part of this work, a prototype thruster head with a 17.8-GHz microwave resonant cavity was designed per dimensions determined from previous research and machined for experimentation. The candlestick antenna used in the design was optimized by varying its height above the bottom of the cavity and examining the reflected power measurements on a network analyzer. The rest of the testing setup was assembled for use with helium propellant. The power system consisted of a microwave signal generator driving a traveling-wave tube amplifier.
