Nasa has begun the final preparations for its Artemis II mission, clearing the way for a launch on Wednesday evening.It will be the most ambitious crewed space mission since the Apollo program more than 50 years ago, with the four-person crew set to travel around the Moon on a 10-day journey. The test mission is designed to lay the groundwork for future lunar landings, with the first one currently scheduled to take place in 2028 as part of the Artemis IV mission. The US space agency said the current forecast for Wednesday’s launch shows an 80 per cent chance of favourable weather conditions, with potential cloud cover and high winds in the area.
