Summary
VEP 4, CE-SAT-1E & TIRSAT launched on a Mitsubishi Heavy Industries H3-22 from Yoshinobu Launch Complex LP-2, Tanegashima Space Center, Japan on February 17, 2024 at 00:22 UTC. The launch window ran from 00:22 to 04:06 UTC. It was Mitsubishi Heavy Industries's 50th launch, 2nd this year and humanity's 6,621st orbital launch attempt. It was the 2nd H3-22 flight and the 1st this year. The payload was bound for Sun-Synchronous Orbit (SSO). CE-SAT-IE, one of 3 catalogued objects, reached a 676 × 689 km orbit inclined 98.1°. 3 objects from this launch are catalogued, all of them payloads.

About this launch
New test flight of the H3 ordered following the failure of the inaugural launch of H3 in March 2023 with ALOS-3. Main payload is VEP 4 (Vehicle Evaluation Payload 4), a 2.6 tonnes mass simulator payload that will be carried on the 2nd test flight of the H3 rocket, instead of the ALOS-4 Earth observation satellite as originally planned. It will be deployed after the 2nd de-orbit burn is completed to test the payload separation mechanism. 2 hitchhiking secondary payloads have been selected in June 2023: * CE-SAT-1E - 70 kilograms class optical Earth observation satellite from Canon Electronics Inc., similar to the previously launched CE-SAT-1. * TIRSAT - 3U cubesat by Japan Space Systems and other institutes to test an infrared sensor for Earth surface observation purposes.
