...starting a new thread for Hayabusa's sampling feedback and the return voyage.
After its nail-biting success in November, will there be enough fuel for the Falcon to make it home? -------------------- --O'Dave

According to the L/D of the Matsuura Shin 也... Bulletin * The possibility the bullet not being discharged is high * It has not recovered the thruster * Ion using the engine, attitude control (Correction: Speaking accurately, applying the function of the ion engine system, attitude control) * I To matte (Itokawa) as for starting even with most speed after 14 days * Concerning return undecided From blog: Paku http://translate.google.com/translate?u=ht...Flanguage_tools Brief summary from the blog: Matsuura' newspaper December 2nd. The chemical engine (the thruster) restart was tried, but small thrust is verified in earnest not to start. December 3rd, it was verified that the high gain antenna axis of the probe and the angle which the sun and the earth form have expanded to 20 or 30 degrees. As the attitude control method of emergency, the xenon gas for ion engine driving it starts the compilation of the operational software to the thing which does the attitude control with the injection. December 4th, it executes the attitude modification with the xenon gas injection. December 5th, the sun, the earth and the high gain antenna axis recover to 10 degree - 20 degrees, presently by way of the medium gain antenna communication does at speed of 256 bit /s. However, because the probe slowly is turning, as for the communication by the medium gain antenna intermittence ones such as 1 minute in 6 minutes. As of December 6th, it is (Hayabusa) quick the (Itokawa) ぶ, from the I To matte in gaze direction it is in the place of the 550km. As for distance from earth 2 hundred million 9000 ten thousand km. Presently just 1 basis the reaction wheel which remains verifies the recovery moving and the revolution with the 1000rpm. In the other word, now Hayabusa is around 550 km distance from Itokawa and is 290,010,000 kilometers from Earth. (almost just in the opposite side) The RCS z-axis still works at 1,000 rpm. Rodolfo |
