The Nuri-ho, whose launch was delayed due to an oxidizer sensor error, is currently in the midst of investigating the cause in the assembly building.
It is unclear whether the schedule will be rescheduled within the next 23 days, the deadline for the preliminary launch date.

The Korea Aerospace Research Institute held a meeting at 9 am today (16th) to discuss how to check the signal abnormality of the oxidizer tank level sensor.
The oxidizer level sensor is a facility attached to the lid of the first stage oxidizer tank of Nuriho, and serves to measure the filling level of liquid oxygen, an oxidizing agent.
Yesterday the Nuri was before the oxidizer was charged, so the oxidizer tank was empty, but the sensor did not display the value that should be displayed when the tank is empty.
Oxidizing agents and fuel make up 90% of a rocket's weight, so it's very important to measure the exact amounts.
The research team moved the Nuri to the assembly building around 10:30 last night as it was determined that it was difficult to determine the cause while it was standing on the launch pad.
The Korea Air Defense Agency announced that it would focus on identifying the cause of the sensor malfunction before setting a future launch date.
[Koh Jung-hwan / Head of Aerospace Research Development Division: The sensor itself may be strange, and then the cable connecting the sensor may be strange.] Once the
cause is identified and corrected, the launch schedule will be scheduled in consideration of the weather conditions, etc. It is unknown whether the launch will be possible within the next 23 days.
In particular, as the rainy season and typhoons are expected to begin at the end of June, the launch may be delayed by several months.
