The fuel tanks of Progress are almost empty at the moment and the necessary fuel was transferred back from the storage tanks in Zarya module. The Russians quoted the (planned) velocity increase as 3.0 m/s (10 fps), but it is not clear to me, whether this is total change of two parts of correction summed, or 2 x 3,0 m/s (probably TOTAL impulse is meant). This correction (albeit used for increasing the mean height too) was rendered as test maneuver only. Another two-impulse correction is planned on 2002-03-13 with (total?) velocity increase of 6.7 m/s and similar scenario (ie. fuel + oxidizer transfer from Zarya module). --- Antonin Vitek Office: Main Library - Academy of Sciences of the Czech Republic Narodni 3, CZ-115 22 Praha 1, Czech Republic Phone: +420(2)21 40 32 55 **** Note change in phone no. **** Fax: +420(2)24 24 05 26 E-mail:AVITEK@LIB.CAS.CZ My satellite home page: http://www.lib.cas.cz/knav/space.40/index.html Home: Kytin 127, CZ-525 10 p.
