The Japanese Earth-Observation satellite ALOS, developed by JAXA and launched on 24 January 2006, had the objective to provide the user community with data of sufficient resolution to be able to generate 1:25,000 scale maps.
The mission included optical and an active L-band SAR sensor payload whose high-resolution data may be used for environmental purposes.
On 22 April 2011, the ALOS satellite was lost due to a power anomaly and completed its operations phase.

Following major development activities, which caused data access unavailability over the last months, ESA has now made all of its archived data from the PALSAR instrument available again. The new ground segment architecture allows for faster data access, as data requested by the user will be provided out of the archive and processed "on the fly". No more manual intervention for processing will be necessary on ESA's side. WB1 PALSAR data will become available in the next months.

As previously mentioned in the news of 25 April 2016, ESA is developing a new ground segment to offer the possibility to have online access to all of the ALOS data available at ESA.
ALOS AV2 PRISM data will be available for users from Q2 2017.
