Nuri, which had delayed its launch due to an electrical sensor error, moved to the launch pad today (20th).
Inspection and other works are in full swing ahead of tomorrow's launch, but the weather at the Naro Space Center is expected to be the last variable.

The Nuri left the projectile assembly building at around 7:20 am and moved slowly to the launch pad at a speed of 1.5 km/h.
It's only been five days since the launch was delayed last week by more than an electrical signal.
At 8:44 a.m., 1 hour and 24 minutes later, the construction of the Nuri-ho, which arrived at the launch pad, begins.
After two and a half hours of work, at 11:10 am, the Nuri stood tall on the launch pad.
In the afternoon, I connect the Nuri to the umbilical tower on the launch pad to charge the Nuri power supply and propellant.
The launch time is likely tomorrow at 4 pm, and the final launch time is determined by comprehensively analyzing the state of the launch vehicle on the day, weather conditions, and the possibility of colliding with space objects.
The first stage oxidizer tank sensor, which became a problem last week, replaced the part, and the problem of the third stage oxidant tank, which was the cause of the failure of the first launch, was also corrected.
The core of this launch is a satellite mounted on a rocket, and unlike the last time when only a model was loaded, this time, an actual performance verification satellite weighing 162.5 kg was loaded.
If the launch is successful tomorrow, Korea will join the ranks of space powers that launched the world's 7th medium-large liquid rocket.
However, until the end, the weather is a variable.
The weather at Naro Space Center is predicted to be cloudy tomorrow, but the Korea Aerospace Research Institute is planning to confirm the final launch plan by looking at clouds that can cause lightning near the launch trajectory.
