Abstract

Power generation in extreme environments, such as the outer solar system, the night side of planets, or other low-illumination environments, currently presents a technology gap that challenges NASA's ambitious scientific goals. We are developing a radioisotope power cell (RPC) that utilizes commercially available tritium light sources and standard 1.85 eV InGaP2 photovoltaic cells to convert beta particle energy to electric energy. In the test program described here, we perform environmental tests on commercially available borosilicate glass vials internally coated with a ZnS luminescent phosphor that are designed to contain gaseous tritium in our proposed power source. Such testing is necessary to ensure that the glass containing the radioactive tritium is capable of withstanding the extreme environments of launch and space for extended periods of time.

Scott Hudson Keywords: Optically injected circuits; Remote power; CMOS logic; Telemetry; Wireless biomedical implants; Contactless smartcards Abstract: This paper reviews the concept of optically injected logic circuits and investigates their implementation in nanometer CMOS technologies. Optically injected circuits are powered via an optical beam, i.e. they do not require a local power supply and distribution network. A complete set of digital cells has been designed and simulated, and key building blocks of the logic family have been fabricated and tested in a standard 180nm CMOS technology. The paper also discusses the design and implementation of optically injected circuits for clock distribution, input/output, analog-to-digital and digital-to-analog conversion. All these circuits are immediately applicable in wireless biomedical implants or contactless smart cards. They can also be used in other systems-on-chip (SoC), in which very low power operation can be replaced by remote-powered operation.

Abstract

Cosmic Infrared Background ExpeRiment-2 (CIBER-2) is an international project to make a rocket-borne measurement of the Cosmic Infrared Background (CIB) using three HAWAII-2RG image sensors. Since the rocket telemetry is unable to downlink all the image data in real time, we adopt an onboard data storage board for each sensor electronics. In this presentation, the development of the data storage board and the Ground Station Electronics (GSE) system for CIBER2 are described. We have fabricated, integrated, and tested all systems and confirmed that all work as expected, and are ready for flight.

19. A Custom Launch System for Satellites Smaller than 1 kg

Author

Patru, Dorin, Kozak, Jeffrey, and Bowman, Robert

Abstract

This paper presents the concept and design of a custom launch system for satellites with a mass equal or less than 1 kg. Current launch opportunities carry these satellites as secondary payloads to orbit. To date, no launch system has targeted a satellite of less than 1 kg as a primary payload. The case is made for an airborne, balloon based rocket launch. A four stage rocket using a hybrid propellant combination is proposed. With an assumed specific impulse of 235 seconds, four stages and a redundant structure to propellant mass ratio of 1/10, a burnout velocity of 9,200 m/sec can be achieved. Subtracting the velocity losses due to drag in the upper atmosphere, gravitation and earth rotation, a real burnout velocity of more than 7,600 m/sec can be achieved, which is sufficient to achieve Low Earth Orbit. The initial mass of the rocket and payload would be below 200 kg. For currently available zero-pressure balloons, this is an average payload which can be lifted up to 30 km in about an hour.
