On the 11th, a press release of the advanced radar satellite "DAICHI-4" (ALOS-4) was held at Mitsubishi Electric Kamakura Works.The launch is scheduled for 2024, and will carry on the mission of ``DAICHI'', ``DAICHI 2'', and ``DAICHI 3'', which unfortunately failed to launch, and will expand Japan and the world with an observation device using the world's first technology. I'll watch over you from space.
... First stage of H3 rocket No. 3The original plan was for the Type 30 to be equipped with three LE-9 engines, but it was changed to the Type 22, equipped with two LE-9 engines and two solid rocket boosters. Both engines will be installed at Tanegashima Space Center....On March 21, 2024, the Japan Aerospace Exploration Agency (JAXA) and Mitsubishi Heavy Industries unveiled the third vehicle of the "H3" rocket at the Mitsubishi Heavy Industries Nagoya Aerospace Systems Works (Tobishima Village, Aichi Prefecture). Regarding the satellite to be launched with Unit 3, JAXA is envisioning the Earth observation satellite ``Daichi-4'' (ALOS-4).
QuoteThe new STA is intended to cover multiple launches using H2A and H3 launch vehicles during which Comtech’s monitoring services will be required. The first launch using an H3 rocket (F3) is expected to occur as early as June 15, 2024, which would be covered under Comtech’s current STA if launched on that date, but with a launch window extending until July 31, 2024, more than a month after the current STA’s expiration. The payload to be placed in earth orbit will be Advanced Land Observing Satellite-4 (ALOS-4)/SSO to be launched from Tanegashima Space Center (“TNSC”) in Japan.The second identified launch, which will use an H2A launch vehicle (F49), is expected to occur at the end of the third quarter of 2024. This satellite is an Information Gathering Satellite (IGS)/SSO and is also to be launched from TNSC. Additional launches using these same classes of launch vehicles may also be scheduled during the STA period...

Launch Result of the Advanced Land Observing Satellite-4 “DAICHI-4” (ALOS-4) aboard the third H3 Launch Vehicle (H3 F3)July 1, 2024The Japan Aerospace Exploration Agency (JAXA) launched the Advanced Land Observing Satellite-4 “DAICHI-4” (ALOS-4) aboard the third H3 Launch Vehicle at 12:06:42 (JST) on July 1, 2024 from the Tanegashima Space Center.The Launch Vehicle flew as planned, and approximately 16 minutes and 34 seconds after the liftoff, the separation of the “DAICHI-4” was confirmed.JAXA appreciates all for the support shown in behalf of the launch of the third H3 Launch Vehicle.
Status of Advanced Land Observing Satellite-4 "DAICHI-4" (ALOS-4)July 1, 2024The Advanced Land Observing Satellite-4 "DAICHI-4" (ALOS-4) was successfully launched on the third H3 Launch Vehicle (H3 F3: Flight No.3) from the Tanegashima Space Center at 12:06:42 on July 1, 2024 (JST).The full deployment of its solar array paddles was confirmed by telemetry data received from "DAICHI-4" at the JAXA Mingenew Station, Australia at 12:25 on the same day (JST).Following this, the signal from "DAICHI-4" was received at the Santiago Station in Chile at 12:59 (JST), and it was confirmed that "DAICHI-4" is now in nominal condition with Sun Acquisition Mode.JAXA including the ALOS-4 Project Team will continue to work together with the prime contractor, Mitsubishi Electric Corporation, and other companies and organizations involved in satellite operation.
