NASA's Artemis II mission completes a critical engine burn, propelling the Orion spacecraft and its four-person crew out of Earth orbit toward the moon.

NASA plans to launch a nuclear-powered spacecraft to Mars by 2028, a major step for deep space exploration and its planned moon base.

NASA engineers manage propulsion systems and space communications to maintain Artemis II’s schedule, ensuring the Orion spacecraft and crew remain connected from launch to splashdown.

Returning to the moon and building a base will pale in comparison to what we will be capable of accomplishing in the years ahead,” Isaacman said.

NASA's Artemis 2 has launched on a history-making journey around the moon and back, and the moment was captured from space.

As NASA prepares for its Artemis II mission, a Central Florida man who helped make the first moon landing possible is reflecting on decades of progress in space exploration.

Artemis II mission will take 4 astronauts on a trip around the moon. The vehicle that will send them there? A massive NASA Space Launch System rocket.

Now more than halfway to the moon, the Artemis II astronauts prepared for their historic lunar fly-around to push deeper into space than even the Apollo astronauts. On the downside, their toilet is on the blink again.
