Astronauts name SpaceX spaceship 'Endeavour' after retired shuttle

May 30, 2020

— The first NASA astronauts to launch from the U.S. since the end of the space shuttle program have named their commercial spacecraft after one of the retired winged orbiters.

Doug Hurley and Bob Behnken revealed the name of their SpaceX Crew Dragon capsule during a live broadcast from Earth orbit, about three hours after they lifted off from NASA's Kennedy Space Center in Florida on Saturday (May 30).

"I know most of you, at SpaceX especially, know it as 'Capsule 206,' but I think all of us thought that maybe we could do a little bit better than that," Hurley said, in part addressing the team in SpaceX's mission control at the company's spacecraft and rocket assembly facility in Hawthorne, California. "So without further ado, we would like to welcome you aboard capsule 'Endeavour.'"

Hurley said there were a couple of reasons why he and Behnken chose the name.

"One, because of this incredible endeavor [that] NASA, SpaceX and the United States has been on since the end of the space shuttle program back in 2011," he said, referencing the space agency's commercial crew program that led up to their orbital launch, the first in nine years from a U.S. launchpad and the first-ever by a commercial company.

"The other reason we named it 'Endeavour' is a little more personal for Bob and I. We both had our first flights on shuttle Endeavour, and it just meant so much to us to carry on that name. So that is what we decided to go with," he said.

Hurley's first launch was as the pilot of the shuttle Endeavour's 23rd mission, STS-127 in 2009. Behnken preceded him aboard orbiter by two flights, launching as an STS-123 mission specialist the year earlier.

Behnken flew again on Endeavour on STS-130, the orbiter's penultimate mission, in 2010. Hurley also flew a second time on the space shuttle, but aboard Atlantis, as the pilot of the final flight of the shuttle program, STS-135 in 2011.

The Crew Dragon Endeavour has little in common with the space shuttle, having been designed by SpaceX to be a 21st century vehicle.

"We're doing [this] in a brand new spaceship," said Behnken, "that is a lot different than its namesake — Endeavour, the space shuttle — in that it has touch display screens that allow us to accomplish most of the interfacing requirements that we have."

Although the shuttle orbiters, including Endeavour, were upgraded with "glass cockpits" that replaced many of their analog dials and gauges with digital displays, they were flown using buttons, switches and a physical hand controller (or stick). By comparison, SpaceX's Dragon is outfitted with touchscreens and can fly autonomously, though it too have some buttons for key functions and commands.

The crew's decision to christen their capsule continues a tradition that dates back to the early U.S. space program.

"[This] is a tradition that we have had over the years with spacecraft going way back to the Mercury-era," said Hurley, "a tradition that has been carried on ever since with all of our space vehicles."

The original U.S. spacemen, the Mercury astronauts, were the first to give names to their capsules, beginning with Alan Shepard's "Freedom 7" (the seven being in reference to the pilots being collectively known as the "Mercury 7"). Later, the Apollo astronauts chose names for their spacecraft, in part to serve as call signs for when they were flying their command modules and lunar modules separately.

The first four space shuttle orbiters to launch into space were named by NASA for "sea vessels used in world exploration." Endeavour, which was built to replace the ill-fated shuttle Challenger, was named in a national competition for schools after the HMS Endeavour, the ship which took Captain James Cook on his 18th century voyage of discovery.

The Crew Dragon Endeavour is now the third U.S. crewed spacecraft to bear the name, after the retired orbiter and the Apollo 15 command module Endeavour that orbited the moon during the fourth moon landing mission in 1971. It also is the second commercial crew capsule to be named after a historic ship (by way of the space shuttle's namesake).

In December 2019, NASA astronaut Suni Williams was given the honor of picking the first name given to a CST-100 Starliner, Boeing's commercial spacecraft that will also fly crews to the space station. Williams, who is assigned to launch on the first operational Starliner mission, chose "Calypso" to honor Jacques Cousteau's ocean research vessel.
