Spin Stability Of Sounding Rocket Secondary Payloads Following High Velocity Ejections, Weston Mcclain Nelson
Spin Stability Of Sounding Rocket Secondary Payloads Following High Velocity Ejections, Weston Mcclain Nelson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Auroral Spatial Structures Probe (ASSP) mission is a sounding rocket mission studying the effects of solar energy on space weather. ASSP requires the high speed ejection (up to 50 m/s) of 6 secondary payloads to gather the required data. The scientific instruments on the secondary payloads require that the payloads are stable in flight with coning angles of less than 5º, where the coning angle is the amount the payload is allowed to “wobble” about its spin axis. The secondary payloads are also required to have their spin axes aligned with 25º of the local magnetic field lines. Current …

Small Satellite Conference
Six years ago, CNES started R&D studies related to telemetry in X band, with the goal of providing to micro satellite platform manufacturers a low cost but high performances X band transmitter. The promising results achieved have led to the decision to develop a transmitter for ESA PROBA-V spacecraft to be launched in 2013. The first flight models have been designed in only 18 months and will be delivered to ESA in February 2012. In the same way, CNES is now studying a solution to download telemetry in X band for cube and nano satellites. The aim is to provide …

The Antarctic Broadband Demonstration Nanosatellite: Fast Internet For The Bottom Of The Earth, Grant Bonin, Robert Zee, Michael Brett, Jan King
Small Satellite Conference
High bandwidth communications is the largest sector of the commercial satellite industry. While micro- and nanosatellites have yet to service this market on a commercial basis, it is expected that such spacecraft will play an increasing role in the communications industry, with initial applications likely to be in niches that cannot be readily or easily addressed by traditional service providers. Antarctica is one such niche. Communication needs in the Antarctic are increasing rapidly, with high growth rates in operational and scientific activities across the continent. Traditional space and terrestrial communication solutions will not be able to meet these needs in …

The Iss As A Launch Platform For Phenomena Of Interest, Phillip Anderson, Bryan Bingham, Charles Swenson, Chad Fish, Joshua Martineau
Small Satellite Conference
The lower ionosphere/thermosphere (150 to 350 km) is the boundary between the sensible atmosphere of the Earth and space. This region receives energy and momentum from both the sun (ultra-violet light and electromagnetic energy coupled via the earth’s magnetosphere) and the lower atmosphere (turbulent waves). These processes act as system drivers and feedback elements, but are still poorly understood, making the weather in this region unpredictable. Few observations of these processes and their coupling are available and no validation of the predicted fundamental neutral or plasma processes has been accomplished. Although almost immeasurable themselves, these atmospheric changes have very measurable …

Small spacecraft have an enviable history of changing the economics of space. Space development and exploration has historically been costly, and going beyond Earth orbit even more so. However the cost-performance balance of small spacecraft has increased to the point where new commercial business cases using space infrastructure can be enabled. This paper outlines SSTL’s approach to low cost missions, and its validity to exploration, in particular the Moon. The political environment for supporting space missions, particularly exploration in the United Kingdom is covered, including study activities building the case for a national exploration programme and their fit to strategic …

Micro-Inspector Spacecraft An Overview, Hannah Goldberg, Juergen Mueller, Leon Alkalai
Small Satellite Conference
JPL has completed design of a small (< 5 kg) spacecraft capable of visual inspection of a host vehicle with support from NASA’s Exploration Systems Mission Directorate (ESMD). The Micro-Inspector is designed to have a minimal impact on the host with respect to mass, size, cost, interface, and integration. On orbit, the host provides the separation signal to the Micro-Inspector, ejecting it to autonomously maneuver about the host taking images and communicating them back to the host in real-time. The Micro-Inspector is capable of receiving commands for additional utility. After operations are complete, the Micro-Inspector will go through an end of life disposal, ensuring it is at a safe distance and minimal risk to the host. The Micro-Inspector spacecraft features an FPGA based avionics design with embedded processors, miniaturized celestial sensors and a MEMS-based IMU for navigation, structured light system for hazard avoidance, triple-junction solar cells for power generation and lithiumion batteries for power storage, and a low pressure butane propulsion system, all in a compact and integrated structure, allowing the Micro-Inspector to operate in close proximity to another space object. Extra mass and volume can be used for additional sensors other than visual inspection to provide a more complete analysis of the local space environment. This paper describes the multi-mission utility of the Micro-Inspector and presents an overview of the spacecraft system and subsystem designs, description of a typical inspection mission scenario, and initial hardware demonstrations of key subsystems, partially integrated with each other in a Micro-Inspector testbed at JPL.

Cost-Effective Earth Observation Missions Outcomes And Visions From The International Iaa Study , Rainer Sandau, Larry Paxton, Jaime Esper
Small Satellite Conference
Cost-effective Earth observation missions – how can they be achieved, what are the cost drivers, what are the application areas, and what are the possible obstacles and how are they surmounted? A recently published study1,2 provides a single reference of all aspects connected with cost-effective missions. This paper concentrates on some of the outcomes of that study. User communities which start to conduct or participate in Earth observation missions using small, economical satellites, and associated launches, ground stations, data distributions structures, and space system management approaches are likely to find this information useful.

The Rise And Fall Of The Capital Asset – An Investigation Into The Aerospace Industry Dynamics And Emerging Small Satellite Missions , Stanley Kennedy, Jr., Todd Mosher, Quinn Young
Small Satellite Conference
Many studies have been conducted over the years on the relationship between spacecraft design, mission utility, cost/complexity, and the Aerospace community’s ability to “commoditize” spacecraft designs and/or missions. During the Fifties and Sixties, spacecraft were limited by launch vehicle throw-weight and technical performance limitations, particularly computer processing speeds. During the Seventies and into the Eighties the personal computer revolution enabled more and more processing capability to be utilized in spacecraft bus and mission designs. This resulted in industry developed, large, “Capital” assets that took years to design, develop, integrate, test, and eventually operate. These systems, due to the very nature …

The modular microsatellite concept developed by SSTL has been remarkably successful. It has been used on over 25 missions in the last two decades for a wide range of applications and customers. Its design philosophies are discussed, which have permitted the design to evolve over time, and in particular has permitted space missions to benefit quickly from the continuing development of emerging terrestrial commercial-off-the-shelf technologies. Breakthrough technologies are discussed which have led to increases in capability and utility of small satellite missions. Furthermore, it will be shown that the execution of frequent missions brings its own benefits in providing a …

Lunette: Lunar Farside Gravity Mapping By Nanosat, Henry Spencer, Kieran Carroll, Jafar Arkani-Hamed, Robert Zee
Small Satellite Conference
One significant item of unfinished business in lunar exploration is the mapping of the Moon’s notoriously-irregular gravitational field. This is of interest to science because it sheds light on the lunar interior, to exploration because it may help find useful resources, and to engineers because it is important for planning and operating missions in lunar orbit. Past mapping efforts have been severely hampered by the impossibility of Earthbased tracking of spacecraft over the lunar farside; the farside parts of the resulting maps are of questionable reliability. Many lunar-orbiter proposals have envisioned solving this with subsatellites, but none has yet flown. …

Small Satellite Mars Missions Using Electric Propulsion, Me Price, Ns Wells, Aj Ball, Jc Zarnecki, Fw Taylor
Small Satellite Conference
Two small satellite concepts are presented for low cost Mars system exploration. Both concepts use solar electric propulsion (SEP) to move from a low velocity Earth escape orbit to captured Mars orbits, and so are able to make use of smaller launcher vehicles, while still providing significant payload accommodation, despite their small size. Both missions achieve their Mars system operational orbits in less than 20 months from launch. The Mars Global Atmosphere Survey (MGAS) mission design has a launch mass of 120kg. It uses a QinetiQ T5 ion engine, with around 24kg of Xe propellant, which provides sufficient ÄV for …

Preliminary Design Of A Very-Low-Thrust Geostationary Transfer Orbit To Sun-Synchronous Orbit Small Satellite Transfer, Chris Rampersad
Small Satellite Conference
Small satellites have proven their viability for conducting meaningful missions at a fraction of the cost of larger satellites. Correspondingly, the demand for small satellite missions is increasing as is the need for more sophisticated low-cost satellites. To enable these more advanced missions, this paper analyzes the feasibility of using a low-thrust propulsion system to transfer to a mission orbit from a readily available launch opportunity. Speci¯cally, a geosynchronous transfer orbit (GTO) launch to a sun-synchronous orbit (SSO) small satellite trajectory is examined. The transfer from GTO to SSO orbit is designed using a direct optimization method. Due to the …

Small Satellite Conference
Solar sails have been studied in the past as an alternative means of propulsion for spacecraft. Recent advances in solar sail technology and the miniaturisation of technology can drive these systems much smaller (< 5 kg mass, < 10 m sail diameter) than existing sails, while still having a high delta-V and acceleration capability. With these unique capabilities of miniature solar sails, called solar kites, some very unique space science missions can be achieved which are difficult to be implemented using conventional propulsion techniques. One such unique candidate mission is to study the Earth's magneto-tail. The paper lays out the main design features and technologies of a solar kite mission/platform and demonstrates that a cluster of solar kites with science payloads can provide multiple, in-situ measurements of the dynamic evolution of energetic particle distributions of the rotating geomagnetic tail of Earth. With a unique design, a solar kite proves to be an efficient, affordable and versatile solution for the mission analysed with a significant science return.

The BRIght-star Target Explorer (BRITE) mission plans to make photometric observations of some of the brightest stars in the sky, which are also among the intrinsically most luminous stars, in order to examine these stars for variability with a precision at least 10 times better than that achievable using ground-based observations. Because of the brightness of the target stars, a very small (3cm) aperture telescope collecting light for a camera equipped with a CMOS detector will suffice. The small aperture size and low power consumption of the CMOS detector are compatible with nanosatellite size and power constraints, and so BRITE …

Small Satellite Conference
Recently, there has been an increased interest in using nanosatellites in space science missions due to many unique science mission architectures that are only possible with a nanosatellite constellation. Hundreds of small and lightweight nanosatellites can form an intelligent constellation acting as a distributed network of instruments. In this way, measurements can be obtained that are not possible with traditional single spacecraft architectures. Such a constellation could take simultaneous, in situ measurements of dynamic phenomena in the Earth’s magnetosphere. This type of data is considered to be a critical element in the NASA Sun-Earth Connection (SEC) roadmap. Currently, the SEC …

APL examined technology and space segment options for the polar orbiting spacecraft of the National Oceanic and Atmospheric Administration (NOAA). The principal finding is that the choice of satellite configuration, rather than the particular technology of flight hardware, is the dominant factor that can reduce space segment costs when viewed over a mission life-cycle. For example, the study shows that fewer than half the number of individual instruments-- many of which are quite expensive-- need be purchased and launched over a 15 year period if each of NOAA's polar orbiting satellites were implemented as four small spacecraft rather than one …

Pulsed Plasma Thruster Technology For Small Satellite Missions, Roger Myers, Steven Oleson, Melissa Mcguire, Nicole Meckel, Joseph Cassady
Small Satellite Conference
Pulsed plasma thrusters (PPTs) offer the combined benefits of extremely low average electric power requirements (1 to 150 W), high specific impulse (~ 1000 s), and system simplicity derived from the use of an inert solid propellant. Potential applications range from orbit insertion and maintenance of small satellites to attitude control for large geostationary communications satellites. While PPTs have been used operationally on several spacecraft, there has been no new PPT technology development since the early 1970's. As a result of the rapid growth in the small satellite community and the broad range of PPT applications, NASA has initiated a …

Small Deep Space Mission Telecommunications, G.K. Noreen, A.L. Riley, V.M. Pollmeier
Small Satellite Conference
Unique requirements imposed on deep space telecommunications, such as operation at extreme ranges, have historically led to high cost, one-of-a-kind spacecraft telecommunications systems. Yet future deep space missions must fit within severe cost, mass and power constraints. JPL recently completed a study to find ways of reducing telecommunications cost for future deep space missions. Study team members surveyed designers of proposed deep space missions to characterize their telecommunications needs and design constraints. They identified and evaluated alternative telecommunications systems architectures capable of satisfying these needs and constraints. They traded spacecraft capabilities against DSN capabilities to determine optimal flight/ground combinations. The …
