Watch Rocket Lab Try to Launch an Electron Rocket to Orbit From New Zealand


This weekend, a small rocket company will try to launch its first commercial mission.

It will not be nearly as big a spectacle as the maiden flight of SpaceX’s powerful Falcon Heavy rocket in February, which propelled Elon Musk’s sports car on a trajectory beyond Mars. But Rocket Lab’s Electron is a harbinger of a new breed of rocket — small, cheap, able to be launched frequently — that could prove much more important in the future of how companies send swarms of smaller satellites to orbit.

Rocket Lab will be streaming the launch on the internet from its launch site in New Zealand.

The launch window stretches for nine days, four hours each day. The first opportunity will be on Sunday at 4:50 p.m. New Zealand time. (In the United States, it will still be Saturday, and it will be a late-night show, or 10:50 p.m. Eastern time).

Just like technology on Earth, satellites are getting smaller and now can be launched on smaller rockets. Companies and governments now also see benefits to designing constellations of small satellites to perform tasks that were once handled by one giant, expensive satellite. With this approach, the failure of one satellite can be handled by moving around the remaining satellites. It is also quicker and cheaper to send up a replacement.

There are at least 150 firms working on small rockets, although most probably will never get off the ground.

Some of the most promising are Virgin Orbit, started by billionaire Richard Branson; and Vector Launch and Firefly Aerospace, started by alumni of SpaceX.

Two other promising companies are Relativity Space, which looks to 3-D print most of its rocket, and Gilmour Space, based in Australia.
