Korea's Nuri Rocket Undergoing Final Checks as Early Thursday Launch Nears

The Nuri rocket will deploy 13 satellites including a 512-kg CAS500-3 for space science research, targeting 600 km altitude to enhance South Korea's launch capabilities.

  • Tuesday, the transport of Nuri, formally the Korea Space Launch Vehicle II , to its launchpad at Naro Space Center proceeded two days ahead of its scheduled fourth launch.
  • Carrying CAS500-3 and a dozen cube satellites, the rocket's combined payload is around 960 kilograms, with CAS500-3 weighing 512 kilograms for space-science research at 600 kilometers.
  • At 9:00 a.m., the transfer began from the assembly building, covering 1.8 kilometers on a special vehicle moving at 1.5 kph, about 1.5 hours behind schedule due to weather with installation expected until late afternoon, KASA said.
  • Hanwha Aerospace Co. led full assembly for the first time, marking Nuri's fourth launch under a government plan to transfer space-technology responsibilities to the private sector; the October 2021 first Nuri launch failed to enter orbit.
  • The mission's deployment sequence begins with the medium-sized satellite separating first, followed by two cube satellites at separation intervals of 20 seconds, then Nuri performs a collision-avoidance maneuver and fuel dump to complete its estimated flight time of 21 minutes and 24 seconds.
