The first launch of the H3 Launch Vehicle (H3/TF1)

Mar 7, 2023

The first H3 Launch Vehicle (H3/TF1:Test Flight No.1) launched the Advanced Land Observing Satellite-3 (ALOS-3) “Daichi-3” from the Tanegashima Space Center, on 7 March 2023, at 01:37 UTC (10:37 local time). Because the second stage engine did not ignite as planned, a disctruct command has been sent and the mission was declared lost. The H3 Launch Vehicle is JAXA’s “new flagship rocket aiming at achieving high flexibility, high reliability, and high cost performance”. H3 is designed to offer several variants with “two types of fairings, two or three first-stage engines (LE-9), and zero, two or four solid rocket boosters (SRB-3) to deal with various payload sizes and orbits”.
