The Scientific Committee on Solar Terrestrial Physics (SCOSTEP) is an interdisciplinary body of the International Councilfor Science (ICSU). The main task of the committee is to organize and conduct international program on solar-terrestrial physics(STP) of finite duration in cooperation with other ICSU bodies. The committee was founded in 1966, and has carried out
various international programs such as International Magnetospheric Study (IMS: 1976-79); Solar Maximum Year (SMY: 197981); Middle Atmosphere Program (MAP: 1982-85); and Solar-Terrestrial Energy Program (STEP: 1990-97). Four Post-STEP
programmes over the period 1998-2002 include: STEP-Results, Applications, and Modeling Phase (SRAMP); International Solar
Cycle Study (ISCS); Planetary Scale Mesopause Observing System (PSMOS); and Equatorial Processes Including Coupling(EPIC ). After that, Climate and Weather of the Sun-Earth System (CAWSES: 2004-2008) and CAWSES-II(2009-2013) werecarried out. Detail of the current program, VarSITI (Variability of the Sun and Its Terrestrial Impact) will be presented by anothertalk, but this paper will introduces the history, the structure and the activities of SCOSTEP, and relations with other internationalbodies.

Dept. Earth and Space Science, Osaka University

The COmmittee on SPAce Research (COSPAR), frequently consdiered as ”International Union of Space Sciences”, was established by the International Council of Scientific Unions (ICSU) in October 1958 to continue the cooperative programmes ofrocket and satellite research successfully undertaken during the International Geophysical Year of 1957-58. The ICSU resolution
creating COSPAR stated that the primary purpose of COSPAR was to provide the world scientific community with the means
whereby it may exploit the possibilities of satellites and space probes of all kinds for scientific purposes, and exchange the resulting data on a cooperative basis. Therefore, COSPAR is an interdisciplinary scientific organization concerned with progress on aninternational scale of all kinds of scientific investigations carried out with space vehicles, rockets and balloons.COSPAR’s objectives are carried out by the international community of scientists working through ICSU and its adhering national academies andinternational scientific unions. Under the rules of ICSU, COSPAR ignores political considerations and considers all questions
solely from the scientific viewpoint.
COSPAR has 8 scientific commisions and several panels:
Commission A Space Studies of the Earth’s Surface, Meteorology and Climate
Commission B Space Studies of the Earth-Moon System, Planets, and Small Bodies of the Solar System
Commission C Space Studies of the Upper Atmospheres of the Earth and Planets Including Reference Atmospheres
Commission D Space Plasmas in the Solar System, Including Planetary Magnetospheres
Commission E Research in Astrophysics from Space
Commission F Life Sciences as Related to Space
Commission G Materials Sciences in Space
Commission H Fundamental Physics in SpaceThe main event of COSPAR is biannual scientific assembly, where usually more than 2000 scientists gather from all over theworld. In Japan, COSPAR activity is supported by Science Council of Japan.

International Center for Space Weather Science and Education, Kyushu University

ISWI stands for International Space Weather Initiative. It is a global scientific effort to advance space weather research byinvolving developing nations. Space weather research requires data from ground-based observation from all over the world. Thisrequires the cooperation of developing nations. To enable this, developed nations must support education efforts in developing
nations – this is International Capacity Building. ISWI makes use of existing ground-based arrays. One such array is MAGDAS,
which has 72 magnetometers installed all over the world. The MAGDAS Project is managed by ICSWSE of Kyushu University.
The contributions of MAGDAS to ISWI are outlined in this talk. It is the hope of ICSWSE that the members of AOSWA and otherresearchers of Asia will join the International Space Weather Initiative, which was initially established by the United Nations.

We present science objectives of Software-type Wave-Particle Interaction Analyzer (SWPIA), which will be realized as a software function of Langmuir probes (LP) running on the DPU of RPWI (Radio and Plasma Waves Investigation; PI: J.-E. Wahlund,IRF-Uppsala, Sweden) for the ESA JUICE mission. SWPIA conducts onboard computations of physical quantities indicating
the energy exchange between plasma waves and energetic ions. SWPIA cannot be achieved without onboard inter-instruments
communications, which will be realized by efforts of RPWI, PEP (Particle Environment Package; PI: Stas Barabash, IR-Kiruna,Sweden) and J-MAG (JUICE Magnetometer; PI: M. Dougherty, ICL, UK). By providing the direct evidence of ion energization
processes by plasma waves around Jovian satellites, SWPIA contributes scientific output of JUICE as much as possible withkeeping its impact on the telemetry data size to a minimum.
SWPIA measures the energy transfer process between energetic particles and electromagnetic plasma waves [Fukuhara et al.,EPS 2009; Katoh et al., AnGeo 2013]. SWPIA will be firstly realized in the ERG satellite mission in the Earth’s inner magnetosphere to measure interactions between energetic electrons and whistler-mode chorus. We will apply SWPIA to ion-scalewave-particle interactions occurring in the Jovian magnetosphere. SWPIA clarifies where/when/how heavy ions are energized bywaves in the region close to Ganymede and other Jovian satellites. In SWPIA of RPWI for JUICE, we focus on the interactions
between energetic ions (a few to tens of keV) and ion cyclotron waves (typically less than 1 Hz). SWPIA uses wave electromagnetic field and ion velocity vectors provided by RPWI sensors and PEP, respectively, with referring three-components of the
background magnetic field detected by J-MAG. SWPIA measures a relative phase angle between the velocity vector vi of i-th
particle of charge qi and the wave electric field vector at the timing of particle’s detection (E(ti )) and computes an inner productof W(ti ) = qi E(ti ) · vi , where W(ti ) corresponds∑ to the variation of the kinetic energy of the i-th energetic particle. We accumulate
W for detected particles to obtain Wint = i W(ti ), and we expect statistically significant values of Wint for the case of themeasurement at the site of efficient wave-particle interactions. In this presentation, we discuss details of the implementation ofSWPIA of RPWI and inter-instruments communications among RPWI-PEP-J-MAG of JUICE.

THE ATMOSPHERIC CHARACTERIZATION FOR EXPLORATION AND SCIENCE(ACES) INSTRUMENT SUITE FOR MARS.

The Atmospheric Characterization for Exploration and Science (ACES) instrument suite is designed to address the highest
priority, lower atmosphere goals and investigations identified by MEPAG[1] and to address both exploration technology Strategic Knowledge Gaps (SKGs)[2]. The ACES instrument suite measures atmospheric dust properties, fundamental atmosphericparameters, and the energy inputs that drive the atmosphere in ways that far exceed previous landed experiments.
The data to be returned by ACES is the compre-hensive and necessary type of information that has been sought after by
the atmospheric, aeolian, and Entry, Descent, and Landing (EDL) communities since the Viking Landers provided the first in
situ glimpse of Martian meteorology. The intervening experiments since Viking have only marginally increased the knowledge
necessary to address Mars Exploration Program and Human Exploration and Operations Mission Directorate (HEOMD) goals;
continuing to repeat these meteorological experiments is an exercise in diminishing returns.
In addition to temperature, pressure, and relative humidity, ACES measures for the first time airborne particle concentrationand size distribution, 3D wind components, and infrared and visible radiative fluxes. By combining the unique capabilities ofACES to de-termine turbulent eddy momentum fluxes and dust characteristics, ACES also measures the wind stress that lifts
sand and dust.
The ACES instrument sensors may be accomodat-ed on a rover (Figure 1) or an a stationary lander. A boom for wind andtemperature and in some cases vis and IR radiation flux minimizes potential thermal, mechanical and radiative contamination by
the space-craft.
ACES is strengthened by internationally contribut-ed sensors and electronics from the U.S.A., Finland, Denmark, Canada, andBelgium. The ACES science team is comprised of exceptional scientists and engi-neers from each of these countries.
Details on the capabilities and response of each in-strument, power requirements, accommodation, ob-servation strategy, anddata products and volume will be detailed in the talk.

SASAKI, Sho1∗ ; YOSHIKAWA, Akimasa21Dept. Earth and Space Science, Osaka University, 2 Dept. Earth and Planetary Sciences, Kyushu University

International collaborations are becoming an important aspect of successful planetary and space science projects. In today’s
research environment, scientists and engineers from all over the world must work increasingly together in a variety of research
projects, including ground-based observations, laboratory experiments, data analyses, archival studies, and numerical experiments. For future advancements in planetary and space sciences, it is important to consider the role of international collaboration, and facilitate interactions among researchers at all career levels from countries all over the world. However, international
collaboration comes with its own set of challenges.
Here in this session, we discuss recent recent achievements and current status of various international projects and also we
confirm roles of international organizations which are mostly scientifically-oriented.
