A final panel session titled 'Prospects for Space Prefecture Kanagawa' featured Kanagawa Prefecture Director of Industry and Labor Nobu Kuroiwa, JAXA Institute of Space and Astronautical Science Director Masaki Fujimoto, Sagamihara Mayor Kentaro Motomura, Mitsubishi Electric Executive Officer and CTO Tomonori Sato, and Koji Yamaguchi as representative director of the Next-Generation Space Systems Technology Research Association and summit executive chair, moderated by television announcer Gido Tsujooka.
The performance deadline for the joint research between Ebara Corporation and JAXA is March 31, 2026.
Ebara Corporation and the Japan Aerospace Exploration Agency (JAXA) signed a joint research contract dated December 26, 2025 to verify performance and develop electric pumps for Orbital Transfer Vehicles (OTVs).
JAXA envisions using OTVs to efficiently transport satellites, probes, and supplies to deep-space destinations like the Moon and Mars.
The joint research contract between Ebara Corporation and JAXA covers electric pumps for OTVs intended to transport multiple satellites to destinations such as the Moon and Mars.
JAXA is considering adopting electric pumps for OTVs to enable simpler engine systems and easier thrust output control and to support infrastructure for future reusable exploration vehicles.
Japan Aerospace Exploration Agency (JAXA) will provide several components for the Ramses mission, including a solar array and a thermal infrared imager.
The Ramses mission may launch as a rideshare with JAXA’s Destiny+ mission aboard a Japanese H3 rocket.
Dell Technologies’ deployment of PowerScale for JAXA ISAS establishes an IT foundation intended to support further advancement of space science research.
JAXA is conducting a cause investigation into second-stage motor combustion anomalies for the Epsilon E-21 motor.
JAXA will conduct a ground static-fire test of the M-35a motor to confirm that it does not contain the same causal factors as the E-21 combustion anomalies.
JAXA will test a re-adapted motor around mid-2026 for the first Epsilon-S Block 1 launch.
JAXA has deferred the larger update of the Epsilon second-stage motor designated E-21.
Epsilon-S Block 1 can support a JAXA high-altitude glider mission to SSO with a maximum satellite mass of 400 kg.
JAXA is considering full-scale motor combustion tests as the final confirmation step to identify the cause of the anomaly.
JAXA plans to use simulated propellant in part of a full-scale motor and to implement a motor design that can stop combustion mid-burn to reduce the risk of explosion during full-scale testing.
Epsilon-S Block 1 can support JAXA’s space technology demonstration acceleration program (JAXA-STEPS) with a target payload mass of roughly 100 kg (TBD).
JAXA will adapt the existing Epsilon second-stage motor as the M-35a for an interim Epsilon-S Block 1 vehicle.
Analysis involving JAXA and external specialists identified vacuum-induced adhesion between metals in space as a likely cause of the metal spheres’ failure to release.
JAXA’s Institute of Space and Astronautical Science (ISAS) has a research facility located in Kanagawa Prefecture.
