QZS-3 (MICHIBIKI No. 3) – H-2A (F35) – Танегасима – 19.08.2017 05:29 UTC

08/19/2017 01:34
Safety officials have established road blocks 400 meters from Launch Pad No. 1 of the Yoshinobu launch complex. The Yoshinobu launch complex was built for the H-2 rocket program that began operations in 1994 and has since been modified for use by the more powerful and H-2A rocket family.

The pads are positioned on a rocky outcrop on the southeastern flank of Tanegashima Island, which lies about 80 miles south of Kagoshima, Japan.

The complex features two pads for the H-2A and H-2B rockets. Launch Pad No. 2 has been used for six flights of the H-2B rocket with the H-2 Transfer Vehicle, an unmanned cargo ship for the International Space Station. In all, 47 rockets have departed Earth from the Yoshinobu complex since 1994. The most recent flight was an H-2A rocket launch in June 2017.

Slew checks of the H-2A rocket's first stage engine have been completed, verifying the powerplant will be able to steer the launcher during ascent.

Fueling of the H-2A rocket's two stages with super-cold liquid hydrogen and liquid oxygen propellants is underway.

Another "go/no go" decision point is coming up soon, before the countdown enters the terminal phase at T-minus 60 minutes.

ロケットはいまのところ連絡も何も無いので、準備が進められていると思います。竹崎からコンデジで撮影。これだけ暑いとゆらゆらですな－。

#HIIA stood fully fueled last Saturday when the launch had to be abandoned because pressure was being lost from the 1st stage Helium system.

Inspections showed a foreign object within the seal of a plug on the Helium tank of the first stage, explaining why decay checks didn't pass

The seal/plug were replaced and re-testing showed good pressure integrity, allowing #HIIA to return to the launch pad. #QZS3
