Rocket Lab called off a launch attempt Tuesday, U.S. time, in New Zealand after encountering a technical problem during the countdown for the company’s first commercial satellite launch. Tuesday’s countdown came after a four-day delay to resolve problems with a downrange tracking station and wait for improved weather.

A Japanese H-2A rocket launched at 5:58 p.m. EDT (2158 GMT) Sunday from the Tanegashima Space Center with the Emirates Mars Mission’s Hope orbiter, the UAE’s first probe to Mars.

Rocket Lab scrubbed a planned launch from New Zealand Wednesday with 10 small Earth observation satellites for customers in the United States and Japan. Officials have not confirmed a new target launch date for the Electron rocket.
