NASA's crewed moon return is drawing ever closer.
Aerospace company Lockheed Martin has finished building the Orion capsule that will fly on the uncrewed Artemis 1 test mission around the moon next summer, U.S. Vice President Mike Pence announced Saturday (July 20) — the 50th anniversary of the historic Apollo 11 moon landing.
The capsule has also been stacked atop its European-built service module at NASA's Kennedy Space Center in Florida, Lockheed Martin representatives said.

"Throughout assembly, the team tested and validated the many systems a hundred different ways to ensure they will operate as designed in the harshness of deep space," Mike Hawes, Orion program manager for Lockheed Martin, said in a statement.
"The Artemis 1 flight will test the design and workmanship of the capsule and its service module during the three-week mission out around the moon and back," Hawes said. "We're excited for this mission as it paves the way for the first crewed mission in 2022, Artemis 2."
Artemis is the name of NASA's ambitious lunar-exploration program, which aims to put two astronauts down near the moon's south pole in 2024. The program also looks to build up a long-term, sustainable presence on and around Earth's nearest neighbor shortly thereafter.
Orion is key to these plans, as is a huge rocket called the Space Launch System (SLS), which is in development. Artemis 1 will mark the first flight of the SLS. Orion has flown once before, on an uncrewed test mission to Earth orbit that lifted off in December 2014 atop a United Launch Alliance Delta IV Heavy rocket.
The plans for Artemis also include building a small moon-orbiting space station called the Gateway. This will serve as a staging point for trips, both crewed and uncrewed, to the lunar surface.
NASA doesn't plan to stop at the moon. The main goal of Artemis is to teach the agency how to live and work in deep space, to help prepare for crewed trips to the ultimate human-spaceflight destination: Mars. NASA wants to put boots on the Red Planet before the end of the 2030s.
