On Thursday, NASA and contractor engineers pumped more than 750 000 gallons of supercooled fuel into the agency's massive space launch rocket (Space Launch System) without any signs of hydrogen leaks or other significant problems, which was an important step for the agency in preparation for the launch of four astronauts in a flight around the moon, which is planned 6 March.
O 9:35 on Thursday morning, the "start" was given to the many-hour pumping process 196 000 gallons of liquid oxygen and 537 000 gallons of liquid hydrogen fuel into the first stage of the SLS rocket. More was loaded into the second stage 22 500 gallons of oxygen and hydrogen fuel.
Unlike the first rocket refueling test earlier this month, when a hydrogen leak forced the team to suspend the countdown, during the second test, the sensors did not detect any significant leaks, and the rocket tanks were refueled without incident.
This will be the first manned flight to the Moon since the last Apollo landings in 1972 year.
