Blue Origin has finished its big rocket.

Jeff Bezos, founder of the space company and, tweeted on Monday photos of Blue Origin's first-assembled BE-4 engine. Two more will be completed shortly, he said.

The BE-4 rocket is part of efforts to end US dependence on the Russian-built RD-180 engine, according to the Blue Origin website. The BE-4 engine is already four years into development and will be flight-ready by 2019, the website said.

Last week, The Washington Post, also owned by Bezos, reported Blue Origin had delivered a white paper to NASA and the administration of President Donald Trump that proposed establishing a colony on the moon. The seven-page document reportedly emphasized cargo missions over transporting people to the lunar surface.

Maybe one-day shipping will be an option.
