Nuri space rocket's second launch set for June 21; sensor malfunction addressed

Next Tuesday, June 21st is the new date the Ministry of Science and ICT and the Korea Aerospace Research Institute have set for Nuri's second launch.
"At first, we thought Nuri's first and second stages would have to be separated to replace the problematic sensor itself but researchers at the Korea Aerospace Research Institute, after close examination, found the issue could be solved by replacing just one key part that was malfunctioning."
After a Launch Management Committee meeting at the Naro Space Center in Goheung, Jeollanam-do Province authorities announced on Friday that they've replaced the core of the oxidizer level sensor in the rocket's first stage that was malfunctioning and confirmed the sensor now works fine.
Engineers first detected the problem on Wednesday, one day before the previous launch date, at two-oh-five in the afternoon while Nuri was standing fully upright on its launch pad which forced them to transport Nuri back to where it was assembled.
"After trying to figure out the issue at the launch pad, we realized it was not possible to get up close and analyze the problem while it's standing up. That's why we decided it's impossible to carry out the launch at the moment."
The sensor's readings were supposed to change in value during the rocket's erection process but reportedly remained static.
Engineers said at the time if it was an issue with the electrical cable or terminal box, fixing the problem wouldn't take too long.
But they feared an issue with the sensor itself could push the new launch date way past June 23rd
the last day of Nuri's alternative launch window possibly to autumn.
Luckily for them, even though it was the sensor that was the problem Nuri will lift off within the window.
Officials have acknowledged, however, that weather conditions still remain a variable.
