In a short caption, the billionaire wrote, "It’s time. #GradatimFerociter." Gradadtim Ferociter is Blue Origin's motto and is Latin for the expression: "Step by Step, Ferociously."
The uncrewed New Shepard blasted off from a West Texas launchpad at Blue Origin’s Launch Site One at 12:50 a.m. ET Wednesday.
"A huge congrats to the entire Blue Origin team on another successful #NewShepard launch. #GradatimFerociter," Blue Origin tweeted following booster and capsule touchdown.
In an accompanying news release, Blue Origin said the 10-minute, 10-second test flight was used to "rehearse astronaut movements and operations for future flights with customers on board" and that the suborbital launch marked a "verification step" prior to flying with astronauts on board.
"For the first time, Blue Origin personnel standing in as astronauts entered the capsule prior to launch. These astronauts conducted a series of tests from within the capsule, including a comms check with the capsule communicator (CAPCOM), procedures for entering and exiting the capsule, and pre-launch preparations within the capsule," it wrote. "Following the crew capsule landing, the astronauts rehearsed post-flight procedures, hatch opening, and exiting the capsule."
However, it noted that while the capsule remained uncrewed for the flight, test dummy Mannequin Skywalker was on board for the ride as well as more than 25,000 postcards from the organization's nonprofit Club for the Future.
In the future, Blue Origin aims to launch as many as six civilian passengers and The Verge reported on Wednesday that the New Shepard missions had been gradually testing new hardware to cater to humans.
While the company has not announced when it will fly humans for the first time, human test flights were initially expected at the end of last year.
