A government committee is expressing concerns over the time it is taking to issue licences for the first launch of satellites into space from UK soil.
The Virgin Orbit plane and rocket arrived at Cornwall Airport Newquay in October ahead of the mission.
The Science and Technology Select Committee said it was “disappointed” the launch had not yet happened.
UK space regulator the Civil Aviation Authority (CAA) said it “continues to work proactively with all parties”.
The committee published a report into UK space strategy and UK satellite infrastructure on Friday.
