NASA has announced a delay for the launch of its historic Artemis II moon mission, now targeting early March after encountering hydrogen leaks during a key fueling test. This marks a setback for the mission that aims to send astronauts around the moon for the first time in over 50 years, with four astronauts currently preparing for the trip. The Artemis II mission is crucial for testing equipment and laying the groundwork for future lunar landings. Cold weather and technical issues during the rehearsal have also contributed to the delay, emphasizing the complexities involved in reopening a new chapter of human space exploration.
