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

Fast-growing launch provider Rocket Lab is launching its second orbital payload of the year late tonight by our reckoning, early in the evening at the launch site in New Zealand. It will carry three experimental satellites to low Earth orbit, and you can watch it live.

The launch is Rocket Lab’s fifth orbital mission, and while it aims to eventually provide launches at a cadence of weeks, it’ll be some time before that’s possible — for now every couple months is what they can manage. But with $140 million in new funding, that should change pretty quickly.

The payloads going up tonight/tomorrow are:

  • SPARC-1: The Space Plug and Play Architecture Research CubeSat is an Air Force Research Lab they’re working on with the Swedish for years now. It’s a new design for a 6U craft with a reconfigurable orbital radio transceiver, intended to “support live experimentation with different waveforms and protocols useful to communications missions.” Plus a camera for checking out the scene up there.
  • Falcon ODE: This Orbital Debris Experiment will release two stainless steel ball bearings on known trajectories in space that will help calibrate ground-based debris-detection systems.
  • Harbinger: A scary-sounding small satellite and the heaviest single micro-sat to be lofted by Rocket Lab’s electron launch vehicle so far. This one, also from the Air Force, uses a synthetic aperture radar to observe Earth regardless of illumination or cloud cover. It’s a demonstrator for rapid production techniques and standardized parts meant to accelerate deployment of new spacecraft.

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, there’s 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.
