NASA Launches Artemis II Even As A Battery Issue Sparks Last-Minute Scramble
Launch window opens at 6:24 ET for Artemis II with four crew. Battery/Launch Abort System issue identified but NASA says it will not delay liftoff.

Launch Fever On Space Coast
Central Florida's Space Coast was abuzz with excitement as NASA prepared to launch Artemis II. Hundreds of thousands of people were expected to gather for the first crewed mission toward the moon in over 50 years. Some visitors took extreme measures to secure prime viewing spots, such as using cable locks to secure chairs.
Battery Issue Sparks Countdown Hold
The countdown was punctuated by last-minute technical challenges involving a Launch Abort System battery. NASA investigated and concluded it was likely an instrumentation issue rather than a battery malfunction. Sky News cautioned the issue could still impede liftoff if it persisted.
Historic Crew Prepares
The Artemis II crew of four astronauts was positioned inside the Orion capsule. They will travel farther than any humans have since Apollo 13. The Atlantic Council described the mission as a critical step toward establishing a sustainable human presence.
Launch and Trajectory
At 6:24 p.m. ET, Artemis II lifted off, initiating a mission that will send the crew approximately 250,000 miles into space.
The primary objectives include testing the Orion capsule's life support systems.

The crew will slingshot around the moon providing opportunities to photograph the lunar south pole.
Continuous Monitoring
NASA's commitment to safety remained paramount even after launch. The Space Launch System and Orion capsule are designed with multiple redundancies. The mission represents the start of a new era of lunar exploration.
