A report on operations from just before launch up to satellite separation (presented in real-time).
Final countdown status of H-IIA Flight F37 carrying Global Changing Observation Mission "SHIKISAI" (GCOM-C) and Super Low Altitude Test Satellite "TSUBAME" (SLATS) will be reported.
The separation of "TSUBAME" has been confirmed.
The separation of "SHIKISAI" has been confirmed.
Mitsubishi Heavy Industries (MHI) has launched the H-IIA Launch Vehicle No. 37 carrying"SHIKISAI" and "TSUBAME" at 10:26:22 on Dec. 23, 2017 JST from the Tanegashima Space Center.
It is 4 minutes and 40 seconds before liftoff. The automatic countdown sequence has started.
It is 30 minutes before launch.
It is 60 minutes before launch. The final countdown operation has started.
The green light has been given to the X-60 minutes terminal countdown operation.
The second attitude control system flight slew test has been completed.
The radio frequency system between H-IIA F37 and the ground stations has been checked up.
It has been confirmed that the first- and second-stage liquid hydrogen and liquid oxygen tanks have been fully loaded.
By running programs of the guidance and control system mounted on H-IIA F37, it has been confirmed that all devices for flight attitude control are working as expected.
Access will now be restricted within a radius of 3,000 meters from the launch pad.
Terminal countdown operation has started. Access will now be restricted within a radius of 400 meters from the launch pad.
Final checks have been made for operational conditions of the launch vehicle, satellites, launch facilities, and tracking and control systems, as well as weather conditions. We now have gotten a go-ahead for loading the propellant, such as liquid oxygen and liquid hydrogen, into the launch vehicle. Propellant loading preparations are going to start.
H-IIA F37 has arrived at the launch pad. The launch vehicle is going to be connected to the pad facilities.
H-IIA F37 carrying "SHIKISAI" and "TSUBAME" has left for the launch pad. H-IIA F37, mounted on the mobile launcher, will travel approximately 500 meters from the Vehicle Assembly Building to the launch pad. This will take about 30 minutes.
This is an updated launch countdown report on the "SHIKISAI"(Global Changing Observation Mission - Climate) and "TSUBAME"(Super Low Altitude Test Satellite) , which will be launched using the H-IIA No. 37 Launch Vehicle (H-IIA F37). After the weather conditions checked out, the green light has been given for H-IIA F37 carrying "SHIKISAI" and "TSUBAME" to leave the Vehicle Assembly Building for the launch pad. The scheduled launch time is Dec. 23, 2017 10:26:22 a.m. JST.
