-JAXA confirmed that the [[IKAROS]] spacecraft has generated the expected acceleration from the pressure of sunlight. This effect has been predicted for over a century since [[wikipedia:James Clerk Maxwell|James Clerk Maxwell's]] studies of electromagnetism. Every spacecraft flown since [[wikipedia:Sputnik|Sputnik]] has been affected, to varying degrees, by sunlight pushing on it. Several [[Category:Missions|missions]] have used solar pressure to their advantage. This is the first time a spacecraft specifically designed to propel itself on sunlight - a true solar sail - has done so. Congratulations to the [[IKAROS]] team on their accomplishment! I look forward to seeing what else [[IKAROS]] will accomplish in the days to come.

-* I saw Mir and the [[Web Links#Past Missions | Znamya 2.5 space mirror] tonight at about 6:55 pm pacific standard time, about an hour after sunset from the countryside near Tacoma, Washington in the U.S. The two spacecraft rose from west by northwest and were separated by about 1 degree. The lead spacecraft was much brighter than any satellite I have ever seen, so I assume it was Znamya 2.5, even though the mirror did not fully deploy. About halfway across the sky, they winked out as they passed into Earth's shadow.

 * Znamya 2.5 space mirror failed to open today for its scheduled illumination test. The mirror snagged on an antenna of the Progress resupply spacecraft from which it was deploying. After two unsuccessful attempts to free the mirror and continue deploying it, mission controllers are considering ending the experiment.
