Rocket Lab unveiled plans for its 'Neutron' reusable rocket, an advanced eight-ton payload class launch vehicle tailored for interplanetary missions and human spaceflight. Neutron will build on Rocket Lab's "proven experience" developing the "reliable workhorse" 'Electron' launch vehicle. Neutron will have a lift capacity of up to 8,000 kilograms to low-Earth orbit and 2,000 kilograms to the Moon.
