Advanced Land Observing Satellite 3 (ALOS-3), also called Daichi 3, was a 3-ton Japanese satellite launched on March 7 2023 which failed to reach orbit. It was to succeed the optical sensor PRISM (Panchromatic Remote-sensing Instruments for Stereo Mapping) carried on the ALOS satellite, which operated from 2006 to 2011. The ALOS-2 satellite and the ALOS-4 satellite carry synthetic-aperture radar.

The satellite was launched as the payload on the first launch of the H3 rocket in March 2023. A failure of the second stage engine to ignite led to the rocket along with its payload ALOS-3 being destroyed by use of Flight Termination System (FTS) to prevent risk of falling debris.
