PLD Space's test is set to be its first step in the race to put small satellites into space and capture a slice of a potential trillion-dollar market.
The launch from a military aerospace research centre in Huelva, southern Spain, would have been the first in Western Europe by a private company.
Europe's efforts to develop capabilities to send small satellites into space are in focus after a failed orbital rocket launch by Virgin Orbit from Britain in January.
PLD Space's "Miura 1" rocket, named after a breed of fighting bulls, is as tall as a three-storey building and has a 100-kg (220-lb) cargo capacity.
