Hello all, Here is the latest manoeuvering schedule for Zvezda according to Vladimir Agapov on July 20 : Date Time,UTC dV,m/s Jul 20 02:47:38 4.76 Jul 23 01:22:42 7.46 Jul 23 01:54:33 10.24 Jul 24 00:37:21 3.00 He also explained : Zarya made two burns of dV=1 m/s on July 18 and Zvezda is manoeuvring to catch up on Zarya toward an "aiming point" at the 219th orbit of Zvezda over the South Atlantic at 00:13:31 UTC on July 26. At that point, Zvezda should be under Zarya at a relative distance in radial direction no more than 1.5 km and relative velocity along line of sight no more than 5 m/s. Relative distances and velocities in two other directions should be equal to zero. After that, Zarya is to fly around Zvezda from above (the aiming point) at a distance no closer than 300 meters and get in front of Zvezda for the final phase of docking. So Zarya should be the leading object in orbit at that time. Initial contact (docking) between both modules is now scheduled for 00:54 UTC on July 26. The exact manoeuvring scheme will be known after the final Zvezda manoeuvres on July 23 and 24.
