SpaceX successfully hit a milestone with the successful launch of a recovered orbital rocket booster. Founder, CEO and CTO Elon Musk told the public it had taken fifteen years to reach that goal, and the next step would be to run spacecraft with a 24-hour launching and landing cycle. The company’s long-term mission is to colonize Mars. The SpaceX website currently advertises 473 job openings. Almost half are for engineers and a third are for technicians. Miscellany include a lobbyist, a cook, and a barista. Not to be outdone, Jeff Bezos’ Blue Origin, which is also developing reusable rockets, posted 92 openings on its website. Half Bezos’ openings will also be for engineers, and another quarter of the hires will be technicians and management. Bezos’ miscellany include university outreach specialists and staff attorneys to help negotiate launch contracts. At last count, Bezos’ New Glenn launchers were 84 feet taller than Musk’s Falcon Heavy rocket.
