Japan IAU Astrophysics Conference, JAXA Gears up for SLIM Lunar Launch to Investigate Moon

August brings a focus on Astronomy in Japan with Asia-Pacific Regional IAU Meeting (APRIM) to be held for first time in Koriyama, Fukushima Prefecture August 7-11. With more than 300 speakers, 20 exhibitors, approximately 500 attendees, the event is sponsored by National Astronomical Observatory of Japan, Mitsubishi Electric, Korean Astronomical Society, and more. Speakers and topics include Astronomers Jean-Gabriel Cuby on Scientific Capabilities of Canada-France-Hawaiʻi Telescope, Yuko Kakazu on Mauna Kea TMT (Thirty Meter Telescope) New Vision and Approach. Also presenting is Valentin Martinez Pille, USA National Solar Observatory, on first results from Daniel K Inouye Solar Telescope at Haleakala Observatory, Maui, and Valery I. Shematovich, Institute of Astronomy, Russian Academy of Sciences, on hot planetary coronas in Solar and extrasolar systems. Satellite meetings will be hosted at University of Aizu, Japan, and National Central University, Taiwan. Japanese Aerospace Exploration Agency (JAXA) continues to progress, preparing for Aug 26 launch of SLIM (Smart Lander for Investigating Moon) via H-2A rocket including secondary payload Spectroscopy Mission (XRISM) destined for GEO.  A joint project between JAXA and NASA, landing target is Shioli Crater within Mare Nectaris, 13° S latitude, 25° E longitude on near side of Moon. SLIM to test pinpoint landing technology with light weight probe system and perform high-resolution X-ray spectroscopic observations of hot gas plasma wind.

Roscosmos Making Final Preparations for Luna-25 Launch to Moon South Pole Region

Luna-25 Moon lander is awaiting launch atop the Fregat upper stage of a fueled Soyuz-2.1b rocket at Vostochny Cosmodrome, set to conduct the first lunar exploration by modern Russia. As inheritors of USSR space / Moon legacy including first satellite to orbit Earth (Sputnik 4, October 1957), first human in space (Yuri Gagarin, April 12 1961) and first robotic soft landing (Luna 9, February 1966), the 1-year nominal mission will clearly be of great significance and perhaps pivotal amid current strife. ~9 science instruments are aboard the NPO Lavochkin-built Luna-25 (1,750 kg wet / 800 kg dry): ADRON-LR neutron / GR regolith probe, ARIES-L exosphere plasma detector, LASMA-LR mass spectrometer, LIS-TV-RPM infrared spectrometer, PmL dust gauge, THERMO-L thermometer, a laser retroreflector, and STS-L panoramic imager. Lunar transfer is expected to take ~5 days followed by 3 or more days in 100-km circular polar orbit followed by 18 x 100 km elliptical landing orbit, depending on whether prime landing (69.545°S, 43.544°E) or alternate site (68.773°S, 21.210°E) is selected – both within 120 km of Chandrayaan-3 prime landing location due for arrival within hours or days of Luna-25. This mission, along with Luna-26 lunar polar orbiter (NET 2027) and Luna-27 South Pole–Aitken basin lander (NET 2028) comprise Russia contributions to the first ‘reconnaissance’ phase of the International Lunar Research Station.
