South Korea’s lunar orbiter Danuuri is fully prepared for a successful launch on Friday, according to the National Aeronautics and Space Administration on Thursday. Developed by the Korea Aerospace Research Institute (KARI) with support from the National Aeronautics and Space Administration (NASA).
Danuri She left Incheon International Airport on July 5 and arrived at Cape Canaveral Space Force Station (CCSFS) in Florida on July 7 on a US rocket.
launch was originally scheduled for Wednesday, but a missile maintenance problem delayed him by two days.
Orbiter was assembled around 3:00 pm on Thursday for final checks before the countdown, including refueling.
Falcon 9 will eject Danuri approximately 40 minutes after launch at an altitude of 1,656 kilometers after the separation of the first and second stages.
His computer launches a program before entering the expected orbit. The first communication with KARI will be possible about 60 minutes after launch.
About four months later, KARI and his NASA colleagues are jointly overseeing the operation.
Danuri uses Ballistic Lunar Transit (BLT), a “low-energy” transfer from the Earth to the Moon that harnesses the gravitational pull of both the Sun and the Earth. This process is energy intensive and can save around 25% fuel, but it will take longer to reach your goal.
Orbiter will first enter lunar orbit on December 16, then make five orbit corrections on December 31 to approach a low lunar orbit below 100 kilometers altitude.
will then run for a month, with 11 months ending in December for functional testing before being fully operational.
Following Friday’s launch, a press conference was held in early June after KARI officials completed a pre-shipment review. They conducted extensive tests simulating the space environment and measured by simulating extreme temperature and electromagnetic conditions.
KARI said the launch would go ahead as planned without any problems.
“It is fully ready for launch, according to assessments by researchers who have closely monitored Danuri since it arrived in the United States,” said his KARI official. “We are aware of the high expectations of the public. We hope that years of hard work by scientists and researchers will advance the nation’s space exploration initiatives. ”
