The US space agency Nasa initially wants to hold on to another launch attempt on Tuesday for the problem-plagued moon mission "Artemis" - however, the weather could make another postponement necessary.

Due to an approaching hurricane, the chance that the weather conditions would allow a launch is currently only 20 percent, NASA said at a press conference.

A final decision should be made at the weekend. Another window provides for a launch of the unmanned rocket between October 17th and 31st. A leak occurred again during a tank test on Wednesday. Nevertheless, the test was completed as planned and all goals were achieved, according to NASA. About three weeks ago, two attempts to launch the unmanned rocket failed - among other things because of a leaking fuel hose.

The rocket system was then initially brought back to the hangar at the Cape Canaveral spaceport in the US state of Florida. Problems had also arisen in earlier "Artemis" tests, which ultimately resulted in a significant delay in the project.

Although it is now initially about an unmanned test flight to the moon, with the program named after the Greek goddess of the moon, US astronauts are supposed to land on the moon again in a few years.
