New Delhi: After glitches causing delays for months, Nasa is all set to launch its most powerful yet rocket to Moon on Wednesday.
The Artemis-1 has been long time coming as its launch has been marred by two unsuccessful attempts and incidents of faulty leaks.
The mission is touted to be the most advanced scientific endeavour since humans last walked on the moon in 1972.
The Artemis-1 mission will climb up skies from the Kennedy Space Centre in Cape Canaveral on Wednesday.
The American space agency aims at demonstrating prowess in technology it has gained over the last 40 years in space research.
Artemis I engineers have been working out the kinks to get ready the rocket after frequent failures.
They have finally given nod to launch the vehicle after reviewing the status of countdown operations and issues that previously troubled the process.
"The mission management team determined there is a low likelihood that if additional material tears off it would pose a critical risk to the flight. Technicians also completed replacing a component of an electrical connector on the hydrogen tail service mast umbilical. While swapping the component did not fully fix the issue, engineers have redundant sources of information supplied through the connector," Nasa said.
