According to the latest audit from NASA's inspector general, the Space Launch System (SLS) rocket designed to take astronauts to the Moon is substantially over budget and far behind schedule. NASA's spending on the Artemis Moon Program is expected to reach $93 billion by 2025, including the $23.8 billion already spent on the SLS system through 2022. That sum represents "$6 billion in cost increases and over six years in schedule delays above NASA's original projections," says the report. One of the issues has been integrating older NASA technology with newer systems. "These increases are caused by interrelated issues such as assumptions that the use of heritage technologies… were expected to result in significant cost and schedule savings compared to developing new systems for the SLS," the audit states.

NASA has released a jaw-dropping video of the moment its deluge system dumps thousands of gallons of water onto Launch Pad 39B at the Kennedy Space Center. The space agency is prepping for the maiden voyage of the $8.9 billion Space Launch System (SLS) rocket, which will require roughly 450,000 gallons of water during ignition and liftoff to counteract the extreme heat and acoustics. In the incredible footage from this month's wet flow test, a torrential stream of water can be seen spewing straight up into the air and washing over the complex before dwindling to a trickle in just a matter of seconds. The latest wet flow test, shown in the footage above, was conducted on October 15 at the Kennedy Space Center's Launch Pad 39B. The SLS rocket will lift off with 8.4 million pounds of thrust, thanks to its four RS-25 engines and two solid rocket boosters.
