Nasa keeping close watch on the weatherpublished at 19:58 BST 29 March
Officials from Nasa say that the weather forecast for Cape Canaveral in Florida is "80 per cent go" for the launch of Artemis II this week.
The launch could come as early as Wednesday evening local time.
Artemis II's crew and ground systems are ready, but the team will monitor cloud and wind conditions on launch day.
As a reminder, the February launch was delayed due to a helium flow issue.
This will be the first crewed lunar mission in over half a century, the last being in 1972.
The roughly 10-day journey will take the four astronauts farther into space than any humans have ever gone.
We are now ending our live stream of today's news conferences ahead of this week's historic launch. There will be another update from Nasa at 17:00 ET on Monday.
Stay with us through this week for all the latest on Artemis II.
