Using Nanosats As A Proof Of Concept For Space Science Missions: Quakesat As An Operational Example , Scott Flagg, Tom Bleier, Clarke Dunson, John Doering, Louis Demartini, Paul Clarke, Lew Franklin, Jeannie Seelbach, Janine Flagg, Mary Klenk, Victor Safradin, Jamie Cutler, Allen Lorenz, Eric Tapio

Small Satellite Conference

Several previous satellites (Cosmos 1809 and Aureol-3) had detected anomalous extremely low frequency (ELF) magnetic field signals prior to and after large earthquakes around the early 90's. There were questions regarding signal levels, signal structure, frequency ranges, timing, and the ambient noise environment that made it difficult to specify larger science satellites to thoroughly test the theory that ELF might be a precursor signal to large earthquakes. An inexpensive nanosat (QuakeSat) was built, launched in June 2003, and flown to help determine the design parameters and values needed to build a research satellite for this mission.

The Most Microsatellite Mission: One Year In Orbit , Simon Grocott, Robert Zee, Jaymie Matthews

Small Satellite Conference

The MOST (Microvariability and Oscillations of Stars) microsatellite, launched from the Plesetsk Cosmodrome in Russia on June 30, 2003, has had a very successful first year in orbit. MOST is an astronomical science mission designed to measure brightness variations as small as a few parts per million in bright nearby stars. This application demands a pointing accuracy that is not normally associated with microsatellites. One requirement for the MOST mission was that the spacecraft point the boresight of the science instrument (a 15-cm optical telescope feeding a CCD camera/photometer) to an accuracy of 25 arcseconds. In practice, the MOST attitude …

On Brown V. Board Of Education's 50th Anniversary: To Integrate Or Separate Is Not The Question, Thomas Kleven

ExpressO

By ending official apartheid, Brown represented a great victory in the struggle for racial justice in the United States. Following more than a decade of inaction as a result of its “all deliberate speed” formulation, and in response to the then prevailing sentiment among the proponents of Brown, the Supreme Court began to push for the integration of school districts that engaged in segregation by law or practice. This integrationist push lasted from the late 1960s to the late 1970s. Beginning in the mid-1970s the Court began to limit the remedies for segregation by law or practice, and beginning in …

Platform For Attitude Control Experiment (Pace): An Experimental Three-Axis Stabilized Cubesat, Jung-Kuo Tu, Shi-Hua Wu, Chen-Chi Chu

Small Satellite Conference

Owing to their low cost, fast development time, and multi-discipline educational purpose, CubeSats have been widely advocated by universities in recent years. However, few have employed three-axis stabilization schemes due mainly to the limitation of power and mass. The PACE, Platform for Attitude Control Experiment for short, is a three-axis stabilizing CubeSat developed at the National Cheng Kung University. It is a 20x10x10 cm3 double cube satellite weight less than 2-kg. A miniature momentum wheel is employed to achieve stability alone the pitch (orbit normal) axis. Magnetic coils are used to generate control torques to stabilize roll and yaw axes. …

The Supreme Court Limits Lawsuits Against Managed Care Organizations, Timothy Stoltzfus Jost

Scholarly Articles

In Aetna Health Inc. v. Davila, the United States Supreme Court revisited the question of whether the Employee Retirement Income Security Act (ERISA) precludes state lawsuits against ERISA plans. The Court held that ERISA preempts damage actions brought against managed care organizations under the Texas Health Care Liability Act because ERISA itself provides the exclusive remedy for challenging ERISA plans' coverage decisions. The Court suggested, however, that health plans might be liable for treatment decisions made by employed physicians. It also volleyed back to Congress the question of whether ERISA beneficiaries should have any remedy for damages caused by coverage …

A Novel Approach To A High Speed, Large Memory Spacecraft Data Storage Unit, Louis Piché, Blair Gordon, Kjell Magnussen, Len Laba

Small Satellite Conference

A high capacity Data Storage Unit is key to the store and forward mode of operation for numerous science and commercial missions and services that generate very high data volumes at high data rates. This paper introduces just such a commercial service in the form of the CASCADE service. In order for this service to succeed, one of the key spacecraft components is the Data Storage Unit, or DSU. Besides high capacity, the Data Storage Unit needs to have a relatively random access, low power consumption, and a reasonable size and mass. There are currently two storage technologies that appear …

The Use Of Small Cell Lithium-Ion Batteries For Small Satellite Applications, Chris Pearson, Carl Thwaite, Nick Russel

Small Satellite Conference

During solar eclipse, spacecraft rely on batteries to power all on-board electrical systems. Advances in battery technology have lead to lighter products that, in turn, allow spacecraft to fly heavier and more capable payloads. AEA Technology has pioneered the current state of the art in the space community1: Lithium-ion battery technology. Traditionally space batteries were composed of a single series connected string of cells. The cells are sized (in terms of capacity) according to mission requirements and so cell qualification programmes for individual missions are common. The small cell approach involves taking Commercially available Off The Shelf (COTS) Lithium-ion cells, …

University-Class Satellites: From Marginal Utility To 'Disruptive' Research Platforms, Michael Swartwout

Small Satellite Conference

The last ten years have seen a tremendous increase in the number of student-built spacecraft projects; however, the main outcome of these programs has been student training and, on some occasions, extremely low-cost space access for the university science community. Because of constrained resources and an inherently-constrained development team (students), universities have not been in a position to develop 'disruptive' space technologies; in order to secure launches, they are forced to build low-capability, high-margin systems using established design practices. However, universities have one inherent advantage in developing 'disruptive' space systems: the freedom to fail. Experimental failure is a basic element …

Real-Time Mission Planning For Responsive Space Lift, Brian Horais, Joe Guerci

Small Satellite Conference

The 2002 Mission Need Statement for Operationally Responsive Spacelift (ORS MNS) “establishes the requirement for responsive, on-demand access to, through and from space. It also requires on-demand, flexible, and cost effective operations.” [RDT&E R-2 Exhibit, PE 0604855F]. A number of activities have been initiated to respond to this mission need, such as DARPA’s RASCAL and FALCON programs, but their primary emphasis is on the launch vehicle. Responsive Space Lift is a function of the launch vehicle, the payload and the process support. Launch vehicles must be capable of inserting payloads into the desired orbits within hours, payloads must be checked …
