JAXA has been addressing global precipitation-related issues under the Global Precipitation Measurement (GPM) Mission by utilizing the 3D precipitation product "Dual-frequency Precipitation Radar (DPR)" onboard GPM core observatory and multi-satellite precipitation product "Global Satellite Mapping of Precipitation (GSMaP)".
We are pleased to inform that the new website called "JAXA Climate Rainfall Watch" is now available, which provides information about extreme heavy rainfall and drought over the world (Fig. 1). You can easily monitor global extreme weather and climate by displaying accumulated rainfall in some temporal scale (daily, pentad, weekly, 10-days and monthly), indices related to extreme heavy rainfall (percentiles*) and drought (SPI**). A specified date after April 2000 can be selected.

Australia has naturally faced many droughts and bushfires, but conditions have been unusually severe this time. Sometime around September 2019, the bushfires continuously occurred around the state of New South Wales in southeast Australia. The fires had been spreading on a larger scale, and a number of massive fires had merged into a "Mega Fire" that was out of control. The fires are unlikely to end entirely even at the end of January 2020.

Figure 1 (left) Standardized Precipitation Index (SPI) in Australia calculated by GSMaP precipitation amount in a month (December 2019), (right)SPI calculated by GSMaP precipitation amount in three months (October-December 2019) in a same way. The relations between SPI value, the range of drought and frequency of phenomenon were classified by WMO (2012). In case SPI value becomes "-1.5 to -1.99", it indicates the situation of "Severe dryness" which happens "once in 20 years". In case SPI value becomes less than -2.0, it corresponds "Extreme dryness" which happens "once in 50 years". These condition shows the possibility of severe drought occurrence which leads to a big social impact.

In this article, we overview the case analysis for the Typhoon Kammuri which brought serious damages in Philippines in December 2019.
The Manila Observatory issued and updated the reports regarding to the Typhoon Kammuri. GSMaP data were utilized as a source of information to capture the status of the typhoon activities.

On October 3-4, 2019, senior managers met in Tokyo for a meeting of the International Space Exploration Coordination Group (ISECG), where JAXA had participated in this board. ISECG, which JAXA has been taking the Chair since 2018, is a coordination forum of 19 space agencies that aims to promote international space exploration.

The agency leaders reviewed the each country’s efforts toward human and robotic space exploration toward Moon and Mars. ISECG leaders also affirmed that the collaborative approaches are the key for the sustainable exploration and released a summary of the meeting.

TOKYO – On October 3-4, 2019, senior managers representing 11 space agencies gathered at a meeting of the International Space Exploration Coordination Group (ISECG) with the purpose of promoting coordinated efforts toward human and robotic space exploration on and around the Moon and Mars.

Hosted by the Japan Aerospace Exploration Agency, JAXA, as the current chair of ISECG, the participating space agencies reviewed the work of ISECG to foster increased space exploration.

In recognition of the growing global effort and momentum toward going forward to the Moon and Mars, the agency leaders affirmed the importance of collaborative approaches for space exploration. The organisations will be developing an updated reference lunar surface exploration scenario, recognising the shared goal of a sustainable operation on and around the Moon directly contributing to enabling human missions to Mars. The lunar surface scenario will be based on new and updated agency plans and their science goals and technology development strategies.

Sustainability is a key for promoting long-term human exploration. The leaders affirmed the roles of the U.S.-led lunar Gateway, which is critical to lunar surface missions, facilitation of scientific discovery, and future deep space exploration. The agencies also noted the shared interest and importance of potential In-Situ Resource Utilisation (ISRU), including the use of water ice on the lunar surface, which may create opportunities in the coming decades.

The leaders also reaffirmed the significant opportunities in the low-Earth orbit (LEO) including the crucial functions of the International Space Station for the preparation and demonstration of human activities toward the Moon and Mars. The agencies also noted the ongoing efforts in LEO to demonstrate advancing systems and technology readiness for upcoming exploration missions.

Under the growing global support and plans for space exploration, the leaders expressed their intent to engage stakeholders and to increase public support to realise sustainable exploration for future generations.

The leaders noted both the near- and long-term opportunities for increased collaboration. They also noted plans for space agency leadership to gather at the International Astronautical Congress in Washington, DC, later this month, to continue discussions on priorities and opportunities for cooperation. ISECG space agencies welcomed the Romanian Space Agency and Swiss Space Office as new member agencies, and also noted the Luxembourg Space Agency’s recent application for ISECG membership.

The meeting in Tokyo included representatives from the Italian Space Agency (ASI), French Centre National d’Etudes Spatiales (CNES), Canadian Space Agency (CSA), European Space Agency (ESA), Japan Aerospace Exploration Agency (JAXA), Korea Aerospace Research Institute (KARI), National Aeronautics and Space Administration (NASA), Polish Space Agency (POLSA), Russian State Space Corporation (ROSCOSMOS), Swiss Space Office (SSO), and the U.K. Space Agency (UKSA).

Japan Aerospace Exploration Agency has agreed to cooperate with Centre National d'Etudes Spatiales (CNES) on the study-phase activities in JAXA’s Martian Moons eXploration(MMX) mission and analysis of Hayabusa2-returned samples.
Hiroshi Yamakawa, President of JAXA and Jean-Yves LE GALL, President of CNES signed the two Implementing Arrangements for MMX and Hayabusa2 cooperation on June 26, 2019.

On the occasion of the visit by Mr. Emanuel Macron, President of the French Republic, to Japan, the exchange ceremony of the signed two Implementing Arrangements took place at the Prime Minister’s Office of Japan in the presence of Prime Minister Shinzo Abe and President Emmanuel Macron.

The MMX mission is planned to observe Mars’ two moons, Phobos and Deimos and to collect surface material from one of the moons to bring back to Earth. It aims to clarify the origin of the Martian moons and the process of evolution for Mars region and to improve technologies required for future exploration.
MMX is currently in the phase of preparation for developing a spacecraft and the launch is targeted in FY2024.

CNES will contribute to this mission by providing the near infrared spectrometer (MacrOmega) and the knowledge and expertise of the Flight Dynamics, as well as by conducting studies of rover which is to be equipped on MMX spacecraft jointly with German Aerospace Center (DLR).

Hayabusa2 is a successor of Hayabusa. By investigating the asteroid Ryugu（type-C asteroid）and collecting samples for return to Earth, it aims to clarify the origins and evolution of Earth as well as organic materials that formed the oceans and the life.
Hayabusa2 was launched on December 3, 2014 and arrived at Ryugu in June 2018. It is scheduled to return to Earth at the end of 2020.

Under this agreement, CNES will provide the infrared spectroscopy microscope (MicrOmega) to be equipped in JAXA Extraterrestrial Samples Curation Center. It will contribute to improve the analysis of asteroid samples. In addition, this agreement stipulates the data policy which defines how to share and manage data from the MicrOmega.
