Persistent poor weather forecast for tomorrow has resulted in another delay for Rocket Lab, as the company says it will not be making a launch attempt for the It's Business Mission on Tuesday.

"With conditions looking more favorable on Wednesday, we are targeting no earlier than 12:30 pm (00:30 UTC) Wednesday 27 June for launch," a Rocket Lab spokeswoman said.

The US orbital launch provider had hoped for a Tuesday launch, after two earlier scrubbed launches. It still has until July 6 to launch its first fully commercial payload into orbit from its launch facility in Mahia.
