The launch of a light-class booster by Rocket Lab, a U.S.-New Zealand company aiming to provide rides to orbit for small satellites, has been delayed to early next year after technical reviews, repairs and unfavorable weather combined to keep the test flight grounded this week.

With a fix in place for a propulsion system alarm that cut short a countdown in the final seconds Monday, U.S. time, Rocket Lab readied an Electron rocket for another try Wednesday night, but unfavorable upper level winds kept the booster grounded. The Electron rocket is awaiting launch on a test flight aiming to deliver three small commercial CubeSats to orbit from a remote New Zealand launch pad.

Rocket Lab counted down to the second test flight of its commercial Electron satellite launcher Monday, U.S. time, but a dramatic computer-commanded abort triggered moments after its engines ignited kept the light-class booster on its New Zealand launch pad for at least two more days.
