D-day for Nuri's 2nd launch: final inspections underway for 4 PM lift-off

There have been a few hiccups along the way, but South Korea's first totally domestically-developed space rocket Nuri is now just hours away from lift-off and is about to be injected with fuel.
For more, we connect live to our Han Seong-woo who's been covering the launch on site in Goheung, Jeollanam-do Province.
Seong-woo, seems the stars have finally aligned and the launch is now unlikely to be called off.
That's right Mark D-day it is
Everything's indicating it'll be a success including the weather: no rain nor strong winds with speeds of just about five meters per second much lower than Nuri's threshold of fifteen.
And taking that into account, this morning's launch management committee has also concluded that final preparations for the launch will proceed as planned.
In just a few hours, South Korea's first entirely domestically developed space rocket will blast off into the skies carrying with it five actual satellites this time they're part of a 1.5 ton payload that includes a 1.3 ton dummy satellite.
The Korea Aerospace Research Institute began last minute inspections for today's launch just a few hours ago.
Since yesterday, the rocket's been standing fully upright on its launch pad next to the umbilical tower where last night, engineers finished connecting the three stage rocket to all of its umbilical cables which will provide it with fuel and oxidizers leading up to lift-off.
"For now, we're preparing for the launch with 4 PM as our target. When exactly the launch will take place will be finalized and announced after Tuesday afternoon's launch management committee meeting where safety issues and other details will be reviewed."
It's great to hear everything's going to plan. No one wants to see another delay, least of all you, I'd imagine, but what's the plan between now and the launch in around four hours from now?
Well, beginning around four hours before the launch, assuming no irregularities arise during last minute inspections, the fuel and oxidizer charging process will begin after which the erector keeping Nuri stable on its launch pad will be removed.
And from ten minutes before blast-off, everything's computerized the automatic pre-launch operation system will take over.
The launch is not in the hands of the engineers at this point meaning they cannot manually abort the system once it kicks in.
Rather, the system will put a halt to the launch sequence automatically if it detects an issue before lift-off.
Nuri will soar into the skies powered by four 75-ton liquid-fuel engines in its first stage, one 75-ton liquid-fuel engine in its second; and one 7-ton liquid-fuel engine in its third.
If successful the launch will make South Korea the seventh country in the world independently capable of sending a satellite weighing over a ton into orbit using domestic technology.
That's all I have for now, Mark, but I'll be back with more in the later newscasts.
Back to you.
