Press Release
...Japan Aerospace Exploration Agency<br />Press Release<br /><br /><br />Advanced Land Observing Satellite 'DAICHI' (ALOS) Power Generation Anomaly<br />April 22, 2011 (JST)<br /><br /><br />Japan Aerospace Exploration Agency (JAXA)<br /><br /><br />The Japan Aerospace Exploration Agency (JAXA) has been operating the Advanced Land Observing Satellite "DAICHI" (ALOS) exceeding its design life of three years, and even after its target life of five years. However, at around 7:30 a.m. on April 22 (JST), we found that the satellite shifted its operation mode to the low load mode (*1), and all the onboard observation devices were turned off due to power generation precipitation. The anomaly was detected through relayed data via the Data Relay Test Satellite "KODAMA."<br /><br /><br />Since then, the power generation has been rapidly deteriorating, and we currently cannot confirm power generation.<br /><br /><br />The DAICHI was launched on January 24, 2006.<br /><br /><br />JAXA is investigating the cause of this phenomenon while taking necessary measures.<br /><br /><br />*1: Low generation mode: the mode to save power consumption to maintain the minimum function of the satellite.JimOhttps://www.blogger.com/profile/14320277948525739714noreply@blogger.comtag:blogger.com,1999:blog-15164221.post-25691431876259943322011-04-22T12:17:36.304+02:002011-04-22T12:17:36.304+02:00An my above comment, substitute "USA 193"...An my above comment, substitute "USA 193" for "USA 129"....SatTrackCam Leidenhttps://www.blogger.com/profile/08711764306071043709noreply@blogger.comtag:blogger.com,1999:blog-15164221.post-11749545862982337342011-04-20T19:49:03.372+02:002011-04-20T19:49:03.372+02:00Hi Jim,

Unless there are clear arguments as to why IGS 1B is less of a danger (for example, if there is much less fuel left as my "educated guess" suggests: or if it has a tank that is structurally much weaker than that of USA 129 and more likely to be destroyed upon re-entry), IGS 1B is indeed "the next case".SatTrackCam Leidenhttps://www.blogger.com/profile/08711764306071043709noreply@blogger.comtag:blogger.com,1999:blog-15164221.post-71785333110851162152011-04-20T19:44:42.689+02:002011-04-20T19:44:42.689+02:00Good alertness!

Now let's keep our eyes on it.<br /><br />I wrote up the media debates and mistakes in 'New Atlantis' magazine:<br />http://www.thenewatlantis.com/publications/down-in-flames It was based on my own professional space operations experience and my long friendship with key personnel on the DoD project, including former astronaut Kevin Chilton, the then-commander of the US Strategic Command in charge of the project.<br /><br /><br />Perhaps this time we can help refute the pessimistic warning with which I closed my 'New Atlantis' article on the mass media misinformation about the true<br />USA-193 hazards: "A well-defined and thoroughly-researched <br />technological hazard assessment has been buried in misinformation. <br />This does not bode well for the next time a space hazard requires action."<br /><br />I guess the 'next time' is now.JimOhttps://www.blogger.com/profile/14320277948525739714noreply@blogger.com
