On Nov. 26, spacecraft Hayabusa challenged the second trial to execute landing on and sampling from the asteroid Itokawa. Hayabusa team confirmed the whole process to have been implemented, and is sure that the team succeeded in sampling materials on the surface of an asteroid for the first time in world history. Detailed data to be sent from Hayabusa will further verify the sampling. Hayabusa started its last descent phase from the altitude of 1 km above Itokawa by command from earth around 10:00 p.m. Nov.25 (JST). It was followed by starting the vertical descent from around 6:00 a.m. Nov.26., and, around 6:25 a.m., Sagamihara Deep Space Control Room sent a command to continue the descent. Hayabusa challenged landing and sampling operation after a hovering phase. Hayabusa team is now sure, through the analysis of telemetry data, that a series of sequence for sampling was successfully done. Hayabusa then flew up to several kilometers altitude with normal solar paddles power, spacecraft attitude, etc. The spacecraft shifted to safe-hold mode because of its attitude dispersion during ascent, and Sagamihara Deep Space Control Room is now carrying out the recovery operation to three-axis control mode. It therefore takes a few more days to obtain detailed data relating the procedure. Instruments onboard are functioning very well. Spacecraft Hayabusa could find, on the surface of Itokawa, the Target Marker dropped Nov.20 among the images taken during descent phase on Nov. 26. On the Target Marker are etched 880,000 names from 149 countries. Left hand side image shows the area named "MUSES Sea" taken at 4:58 Nov.20, and right hand side image was taken at 6:24 Nov.26. A white light spot inside a red circle is the Target Marker with 880,000 names of the people.
