Here are the reasons why NASA is waiting so long to try another Artemis I launch. 

It will be at least a few weeks, rather than just a few days, before NASA's enormous new 

moon rocket can launch its next try after hitting yet another hitch during its most recent 

attempt to fly an unmanned test flight. Numerous factors, such as schedule eccentricitie

potential traffic at the launch site, and NASA's need to be sure it has resolved the most recent 

problems with leaky fuel, might be blamed for the lengthier delay. 

Here's a rundown of what happened on Saturday, September 3: Launch officials entered this 

weekend's attempt to launch the Space Launch System rocket with confidence. The rocket  

then developed a significant leak as it was refuelling with ultra-cold liquid hydrogen 

propellant. And on Tuesday, NASA said that it will start making an effort to fix those 

Mars' dust may hold the key to 3D printing technology there.
