-One of the latest manifestations of miniaturization in space applications is the development of standardized nanosatellite. Recent achievements and future trends of Micro-Electro-Mechanical Systems (MEMS) technology have indicated that microtechnology is the critical technologies of future space programs. Enabling technologies for demanding applications will surely make use of MEMS based compo...

Long lead-time space-weather forecasting requires accurate prediction of the near-Earth solar wind. The current state of the art uses a coronal model to extrapolate the observed photospheric magnetic field to the upper corona, where it is related to solar wind speed through empirical relations. These near-Sun solar wind and magnetic field conditions provide the inner boundary condition to three...

This paper presents a 2009 status review of the ‘‘FOCAL’’ space mission studied by this author and others since 1992 and formally proposed to ESA for consideration after the year 2000. The FOCAL probe is intended to reach distances between 550 and 1000AU to exploit the huge radio magnification provided there by the gravitational lens of the Sun, as predicted by the general theory of relativity....

The Space Weather and Terrestrial Hazards (SWATH) experiment is a small, lightweight and inexpensive payload designed to place into 10wearth orbit a set of instruments for measurement and study of local space hazards. The SWATH instrumentation is designed to utilize the bus being developed for the Miniature Sensor Technology Integration program. The mission has three major scientific objectives...

In this paper, we present a summary of the scientific and technical work that has been pursued in the development of sensing, dynamic tracking, and intelligent acquisition systems for space applications. The most up-to date experimental results will be presented with emphasis on immunity to sun interference and compatibility with Inconel and geometrical target tracking. The paper will conclude ...

Several unexpected astrophysical observations can be explained by gravitationally captured massive axions or axion-like particles, which are produced inside the Sun or other stars and are accumulated over cosmic times. Their radiative decay in solar outer space would give rise to a 'self-irradiation' of the whole star, providing the time-independent component of the corona heating source (we do...

In this paper, we propose that the accelerated electrons in the quiet Sun could collide with the solar atmosphere to emit Hard X-rays (HXRs) via non-thermal bremsstrahlung, while some of these electrons would move upwards and escape into the interplanetary medium, to form a superhalo electron population measured in the solar wind. After considering the electron energy loss due to Coulomb collis...

In this study, by recognizing geographical location changes of the sun-path diagram, we present a selection of sustainable architectural guidelines that influence the climatic element of sunshine. For this purpose, after the introduction of triple zones of the earth in terms of how the sun is exposed(include:Tropical, temperate and polar), the function of the earth's curvature to create geograp...

In this paper, we present the obtained first scientific results from CSIR-NLC mobile LIDAR (LIght Detection And Ranging) and its validation/comparison with other ground and space-borne measurements. The LIDAR results are compared using aerosol measurements from the Stratosphere Aerosol Gas Experiment (SAGE) and Optical depth derived from sun-photometer employed under AErosol RObotic NETwork (AE...
