Watch Rocket Lab launch its second orbital mission of 2019 late tonight

Update: Delayed and they’ll be trying again 24 hours later, so come back tonight. Fairing of the Falcon-ODE payload. All told, its contents comprise 180 kilograms, or nearly 400 pounds, the heaviest load Electron has yet taken off with. Lift-off is set for 6 PM local time in New Zealand, which corresponds to 11 PM Pacific time here in the U.S. If weather impinges on the opportunity, no worries — this launch window stays open for two weeks. You can watch the whole thing starting a few minutes before 11 at Rocket Lab’s website.
