Advanced Land Observation Satellite (ALOS), also called Daichi, is a 4-ton Japanese satellite. It was launched from Tanegashima island, Japan on 24 January 2006 by a H-IIA rocket. The launch had been delayed three times by weather and sensor problems. This was the first Japanese launch since July 2005.[not verified in body]

The satellite contains three sensors which will be used to map terrain in Asia and the Pacific. JAXA hopes to be able to launch the successors to ALOS during FY2011. For minimizing risk JAXA plans to split the mission up into two satellites. [1][Full citation needed]

On 8 January 2008, it turned out that ALOS had lack of accuracy.[2]

The satellite automatically switched to a power-saving mode at 2230 GMT on Thursday 21 April 2011. Later that day, all onboard power was lost.[3][Full citation needed]
