Zvezda Summary Flight Plan Here is a timetable for the launch and docking events that will bring the Zvezda service module up into space to join with the two existing modules of the International Space Station:Note: timetable assumes a July 12, 2000 launch. Launch is currently scheduled for about 1 a.m. Eastern Daylight Time (05:00 GMT). FLIGHT DAY | DATE | EVENT | 1 | 07/12/00 | -- Launch, ascent, orbit insertion
-- Antenna/solar array deploy
-- Motion Control System activation
-- Systems activation
-- Propulsion system preparation
-- Star-tracker activation and test
-- External black-and-white television camera test | 2 | 07/13/00 | -- Verification burn #1 (about one meter per second)
-- Verification burn #2 (about one meter per second)
-- Preparations for flight day: three orbit-raising burns
-- Solar-array test (first set of drive motors -- verifies accuracy of solar array positioning)
-- Inertial-navigation-system telemetry test
-- Star-tracker-navigation system test | 3 | 07/14/00 | -- Maneuver to attitude for raising burns
-- Perform two orbit-raising burns (about 16 meters per second and 26 meters per second)
-- Solar-array test (second set of drive motors -- verifies accuracy of solar array positioning) | 4 | 07/15/00 | -- Maneuver to burn attitude
-- Perform one-orbit correction burn (about 4 meters per second)
-- Regul-telemetry system test | 6 | 07/17/00 | -- Motion-Control System test
-- Inertial-navigation system test
-- Battery-cycling test
-- External black-and-white television camera test | 8 | 07/19/00 | -- Zvezda maneuvered to inertial docking attitude
-- Zvezda, Kurs and Regul systems tests | 9 | 07/20/00 | -- Telemetry analysis
-- Zvezda battery-current measurements
-- Solar-array system test
-- Zarya's Motion-Control System activated | 11 | 07/22/00 | -- ISS maneuvered to initial docking attitude | 13 | 07/24/00 | -- Two Zvezda rendezvous burns
-- Zarya Motion-Control System activated
-- Zarya docking mechanism extended
-- Unity systems powered down
-- ISS orbital-correction burn
-- Unity systems reactivated
-- Zarya Motion-Control System deactivated | 14 | 07/25/00 | -- One Zvezda orbit-correction burn
-- Zarya Motion-Control System activated
-- Final Zvezda maneuver to docking attitude
-- ISS orbital-correction burn
-- Zvezda automatic-rendezvous system (Kurs) activated
-- Solar arrays locked for docking
-- ISS (Zarya) automatic-rendezvous system (Kurs) activated
-- ISS docks to Zvezda
-- Solar arrays resume sun tracking
-- Zarya Motion-Control System deactivated
-- Hooks between Zarya and Zvezda closed for hard mate
-- Zvezda assumes attitude control of the ISS complex |
