Launch sequence of S. Korea's first space rocket
SEOUL, Aug. 19 (Yonhap) -- The following is the launch and satellite deployment sequence of South Korea's first space rocket. Blast off is set at between 4:40-6:20 p.m, Wednesday. (Seoul Time).
- Four days before launch - Battery cells on board Korea Space Launch Vehicle-1
(KSLV-1) and Science and Technology Satellite-2 (STSAT-2) recharged.
- Three days before launch - Weather conditions on launch date checked, with all
systems examined.
- 54 hours before launch - KSLV-1 with STSAT-2 payload moved from rocket assembly
complex to launch pad and fastened to erector arm with final check conducted on
all vital mechanical systems.
- 24 hours before launch - Launch rehearsal carried out to check all rocket
systems and to conduct final check prior to blast off. Weather conditions around
Naro Space Center checked for strong winds, lightning.
- Four hours before launch - All launch systems and preparations are checked with
controllers to determine "go or no-go" for the injection of fuel and high
pressure oxidation agents into rocket. Injection of fuel and oxidation agents
completed two hours before takeoff.
- 18 minutes before launch - Chief technical controller is to make final decision
to move forward or abort launch.
- 15 minutes before launch - Automatic launch sequence begins for final countdown.
- launch - Thrust from main booster engine sends rocket into space with
land-based tracking radars and highspeed cameras following its assent and
collecting data.
- 20 second after launch - KSLV-1, which flew in a slightly north-easterly
direction for 10 seconds after liftoff makes a "kick-turn" and veers south 900m
above launch pad.
- 55 seconds after launch - Rocket comes under extreme stress as it exceeds speed
of sound 7.4km from the ground.
- 215 seconds after launch - Fairings at tip of rocket are ejected 245km from
launch pad at an altitude of 177km to permit separation of second stage rocket
from main booster. Fairings fall to earth.
- 229 seconds after launch - Engine for the first stage main booster is turned off.
- 232 seconds after launch - First and second stage rockets separate 316km from
Naro Space Center at an altitude of 196km, with main booster falling near the
Philippines.
- 395 seconds after launch - Kick motor of second stage rocket ignites at an
altitude of 303km to help position satellite into proper orbit. Rocket 1,052km
from Naro Space Center.
- 453 seconds after launch - Second stage rocket turned off after STSAT-2 reaches
correct trajectory for stable orbit at an altitude of 306km. KSLV-1 travels at
10km per second.
- 540 seconds after launch - Scientific satellite separates from second stage
rocket 2,055km from launch pad, and deploys solar panels. It aligns itself into
proper orbit.
- 13 hours after launch - STSAT-2 to make first contact with controllers at the
Korea Advanced Institute of Science and Technology in Deajeon.
