AI Summary

The launch windows for NASA's Artemis 2 mission are constrained to just 11 days in March and April. This limited timeframe is due to the specific alignment of celestial bodies required for the mission. The mission's trajectory necessitates a precise alignment of the Earth, moon, and sun, which occurs only a few times a year. This alignment creates a brief window of opportunity for the spacecraft to reach the moon without expending excessive fuel. The narrow launch window underscores the complexity and precision required for deep space missions.
