The mission, initially scheduled for 11 November, has been delayed several times due to weather conditions and technical issues.
The payload will include a satellite built by the Polish-Finnish company Iceye, marking the first deployment under Poland’s “MikroSar” programme, alongside a constellation of three smaller satellites developed for the Polish Armed Forces under the “Piast” programme.
A research nanosatellite from the Polish company SatRev, based in Wrocław in southwestern Poland, will also travel on the same rocket.

The Iceye satellite, the largest of the constellation, is equipped with a radar sensor capable of imaging the Earth regardless of weather conditions.
The three Piast satellites will support both Earth observation and the training of military personnel and specialists in space mission operations.
The satellites will be launched aboard a SpaceX Falcon 9 rocket from the Space Launch Complex at the Vandenberg US Space Force Base in California.
The launch window opens at 7:18 p.m. Polish time (10:18 a.m. PST, 1:18 p.m. EST) and will last just under an hour.
The previous attempt was scheduled for Wednesday, 26 November, but was postponed shortly before liftoff.
The final decision on the launch will again depend on weather conditions and coordination by SpaceX.
