Japan Aerospace Exploration Agency (JAXA) launched their X-band defense communication satellite-3 aboard the 4th H3 Launch Vehicle at 15:48:00(JST) on November 4, 2024, from the Tanegashima Space Center.
The Launch Vehicle flew as planned and is being targeted to GEO at 35,786 km from Earth, with the satellite release approximately 29 minutes and 11 seconds after liftoff — the separation of the Kiranemki 3 satellite (also called DSN-3) X-band MILSATCOM satellite-3 was confirmed.
The H3 Launch Vehicle, developed in conjunction with Mitsubishi Heavy Industries (MHI) is Japan’s new mainstay launch vehicle. JAXA’s goal is to provide “easy-to-use rockets” that offer flexibility, high reliability, and great cost performance, developed by always remaining mindful of the users’ perspectives.
These developments are being advanced by the collective efforts of JAXA together with various Japanese companies.
