Temperatures dropped into the 20s over the weekend, yet NASA teams are hard at work preparing for the historic Artemis II liftoff. Here's the latest.

The convergence of the Artemis II and Crew-12 launch schedules adds another layer of importance to Monday’s countdown test at Kennedy Space Center. For the first time since the 1960s, NASA has separate astronaut crews simultaneously in preflight quarantine, a routine measure to prevent crew members from flying to space with an illness.

NASA is providing a 24/7 live feed of the Space Launch System rocket on the launch pad at the Kennedy Space Center in Florida.

The first crewed lunar mission in more than 50 years is on hold as winter weather in Florida forces NASA to push back launch plans for Artemis II. The agency says near-freezing temperatures and strong winds at Kennedy Space Center prompted managers to delay a crucial fueling test — known as the wet dress rehearsal

Nasa has been forced to delay its first crewed mission around the Moon in more than 50 years due to unseasonably cold weather in Florida. The US space agency said that a “rare arctic outbreak” at the launch site meant that the timeline for the Artemis II mission had to be pushed back.

Artemis II echoes the Apollo-era missions that paved the way for the first moon landing — and sets the stage for what comes next.

NASA has begun a two-day practice countdown for its first moonshot with astronauts in 53 years. The dress rehearsal that started Saturday night will culminate with the fueling of the space agency's new moon rocket.
