Electron

An attempt to place three small satellites in orbit on an experimental test flight was halted Friday after two ships strayed into a keep-out zone offshore Rocket Lab’s privately-owned launch base in New Zealand, delaying the Electron booster’s second demonstration mission at least 24 hours.

The second test flight of Rocket Lab’s privately-developed Electron satellite booster could take off from New Zealand as soon as Friday night, U.S. time, after technical problems and high winds kept the rocket grounded during a series of launch attempts in December.

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.
