<div style="text-align: justify; "><b style="font-size: 1rem;">NASA began fueling its new moon rocket Tuesday for a middle-of-the-night launch, its third try to put an empty capsule around the moon for the first time in 50 years.</b><br></div><div style="text-align: justify; "><br></div><div style="text-align: justify; ">Fuel leaks plagued the first two attempts in late summer, then a pair of hurricanes caused more delays. While engineers never pinpointed the cause of the escaping hydrogen, they altered the fueling process to minimize leakage and were confident that all the plumbing in the 322-foot (98-meter) rocket would remain tight and intact.</div><div style="text-align: justify; "><br></div><div style="text-align: justify; ">NASA added an hour to the operation to account for the slower fill-up, vital for reducing pressure on the fuel lines and keeping the seals in place. It seemed to work, with no major leakages reported during the early stages.</div><div style="text-align: justify; "><br></div><div style="text-align: justify; ">“So far, everything is going very smoothly,” said assistant launch director Jeremy Graeber about an hour into fueling.</div><div style="text-align: justify; "><br></div><div style="text-align: justify; ">The rocket was being gassed up with nearly 1 million gallons (3.7 million liters) of super-cold hydrogen and oxygen. After more than four hours, the core stage was fully loaded and fueling was underway on the upper stage.</div><div style="text-align: justify; "><br></div><div style="text-align: justify; ">NASA expected 15,000 to jam Kennedy Space Center for the launch in the wee hours of Wednesday morning, with thousands more lining the beaches and roads outside the gates. The space agency had two hours to get the rocket off, before standing down until Saturday.</div><div style="text-align: justify; "><br></div><div style="text-align: justify; ">The debut of the Space Launch System rocket, known as SLS, had three test dummies but no astronauts inside the crew capsule on top, which NASA hoped to put into lunar orbit.</div><div style="text-align: justify; "><br></div><div style="text-align: justify; ">This first test flight was expected to last three weeks, ending with a splashdown in the Pacific. NASA’s top priority for the $4.1 billion mission is to verify the capsule’s heat shield during reentry, so four astronauts can strap in for the next moonshot in 2024. That would be followed by a two-person lunar landing in 2025.</div><div style="text-align: justify; "><br></div><div style="text-align: justify; ">NASA last sent astronauts to the moon in December 1972, closing out the Apollo program.
