Since 2008, the Japan Aerospace Exploration Agency (JAXA) has carried out annual domestic balloon campaigns from Taiki Aerospace Research Field (TARF). Productive results have been obtained by many projects in academic fields such as atmospheric science, space engineering, cosmic-ray physics, and astronomy. In 2013, an 80,000-m3 balloon made from a 2.8-[Formula: see text]m ultra-thin polyethylene film reached an altitude of 53.7 km, equaling the world record for the altitude of an unmanned balloon. In 2015, JAXA carried out a balloon campaign from Alice Springs in Australia as a precursor of future sustainable overseas activities to compliment the domestic ones at TARF. In this paper, we discuss recent highlights of and future prospects for Japanese scientific ballooning.

Air Shower Array

The Telescope Array is the largest hybrid cosmic ray detector in the Northern hemisphere designed to measure primary particles in 4 PeV to 100 EeV range. The main TA detector consists of an air shower array of 507 plastic scintillation counters on a 1.2 km square grid and fluorescence detectors at three stations overlooking the sky above the air shower array. The experiment and its recent measurements - spectrum, composition, and anisotropy - is reviewed. Recently the construction of the TA Low energy Extension (TALE) detector, which consists of an additional fluorescence detector and an infill array, was finished. TALE lowers the energy threshold of TA down to 4 PeV. We are also constructing the TAx4 detector to increase statistics in particular at the highest energies. The current status and the future prospects of these new TAx4 experiments is reported.

The quest for the elusive dark matter (DM) that permeates the Universe (and in general the search for signatures of physics beyond the Standard Model at astronomical scales) provides a unique opportunity and a tough challenge to the high energy astrophysics community. In particular, the so-called DMindirect searches—mostly focused on a class of theoretically well-motivated DM candidates such as the weakly interacting massive particles—are affected by a complex astrophysical background of cosmic radiation. The understanding and modeling of such background require a deep comprehension of an intricate classical plasma physics problem, i.e., the interaction between high energy charged particles, accelerated in peculiar astrophysical environments, and magnetohydrodynamic turbulence in the interstellar medium of our galaxy. In this review we highlight several aspects of this exciting interplay between the most recent claims of DM annihilation/decay signatures from the sky and the galactic cosmic-ray research field. Our purpose is to further stimulate the debate about viable astrophysical explanations, discussing possible directions that would help breaking degeneracy patterns in the interpretation of current data. We eventually aim to emphasize how a deep knowledge on the physics of CR transport is therefore required to tackle the DM indirect search program at present and in the forthcoming years.

The Social

Social studies of science have flourished within the last decades, making use of numerous intellectual tools from a high variety of academic fields in the social sciences and the humanities (sociology, anthropology, cultural studies, etc.). Game theory, however, has been one tool that has not been put to use too often, in spite of the obvious importance of strategic considerations in the negotiations between the relevant actors in research episodes. In this chapter, the authors illustrate the use of game-theoretical concepts and techniques with the analysis of a nascent research field: asteroid mining.

Endocrine Disrupting

Widespread concerns continue to be raised about the impacts of exposure to chemical compounds with endocrine disrupting activities. To date, the percolation of endocrine disrupting chemical (EDC) effluent into the aquatic system remains an intricate challenge abroad the nations. With the innovation of advanced oxidation processes (AOPs), there has been a consistent growing interest in this research field. Hence, the aim of this paper is to focus one such method within the AOPs, namely, heterogeneous photocatalysis and how it is used on the abatement of EDCs, phthalates, bisphenol A and chlorophenols in particular, using TiO2-based catalysts. Degradation mechanisms, pathways, and intermediate products of various EDCs for TiO2photocatalysis are described in detail. The effect of key operational parameters on TiO2photocatalytic degradation of various EDCs is then specifically covered. Finally, the future prospects together with the challenges for the TiO2photocatalysis on EDCs degradation are summarized and discussed.

Now days we are sending many satellites into the space which are mainly useful for communication. Till now we have sent many satellites and we have dropped many things in the space like those dead particles revolves around the earth in Low Earth Particles (LEO). This derbis became a problem. It will be a risk to other particles which are revolving in LEO. If we doesn’t take any steps it will lead to collisions and destroy all communication system. The Japan Aerospace Exploration Agency (JAXA) Aerospace Research is studying a micro-satellite space derbi removal scheme. This paper discuss about the Key technologies, strategies and specifications of removing derbis satellite

In 2008 two collections were published: the Handbook of Public Communication of Science and Technology, edited by Massimiano Bucchi and Brian Trench, and Communicating Science in Social Contexts: New models, new practices, edited by Donghong Cheng and five other scholars from China, Canada, Belgium and Australia. These books try to define and draw the boundaries of science communication’s field from both a theoretical and empirical point of view. But do we need to establish it as a distinct research field? For a number of decades, a growing community of scholars and communicators is trying to reply positively to this question, but the need to look outside the disciplinary boundaries, to other academic fields, is still vital.
