Live coverage: International Space Station crew lands in Kazakhstan

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.

Rocket Lab’s first mission of 2020 lifted off from New Zealand’s North Island at 9:56 p.m. EST Thursday (0256 GMT; 3:56 p.m. New Zealand time Friday) with a secret payload for the National Reconnaissance Office, which owns the U.S. government’s fleet of intelligence-gathering spy satellites.
