From the Tanegashima Space Center on the southeast portion of the Japanese Tanegashima island, JAXA presents live coverage of the 40th H-IIA mission carrying GOSAT 2 and KhalifaSat into sun-synchronous orbit.

In addition, four nanosatellites will accompany the primary payloads; two of which are 1-unit cubesats.

Launch is currently scheduled for 04:08 UTC (1:08 PM JST), and there's a 12-minute window available should a hold be called at any point.

We're less than a half-hour until the planned T0.

During the 51-minute flight, all six satellites will be deployed into a sun-synchronous orbit at an altitude of 613 kilometers inclined 97.84 degrees.

Their main missions are focused on Earth observations, astronomy, and technology demonstrations.

Mitsubishi Heavy Industries, Ltd. and JAXA successfully launched H-IIA Launch Vehicle No. 40 (H-IIA F40) which encapsulates Second Greenhouse Gases Observing Satellite "IBUKI-2" (GOSAT-2) and KhalifaSat, a remote sensing Earth observation satellite.
at 13:08:00 on October 29, 2018 (JST) from the JAXA Tanegashima Space Center.

The launch and flight of H-IIA F40 proceeded as planned. The separations of GOSAT-2 and KhalifaSat were confirmed respectively at approximately 16 minutes and 09 seconds and 24 minutes and 15 seconds after liftoff.
We express sincere appreciation for all.

The NSF article is calling one of the small satellites Tenkou, while I believe its correct name is Ten-koh.

This launched provided us with probably the most dramatic view of a rocket yaw steering dogleg for as long as I could remember. The ~60 degrees starboard yaw (used in every single polar orbit launch from Tanegashima due to avoiding dropping rocket stages in the Philippines) was much faster than I though - almost like the rocket version of AE86 in Initial D (excuse my pun  ;)) - that for almost 1 minute post SRB separation I thought the launch failed with the rocket losing attitude control and ended up violently tumbling!

Me too. While covering the launch, I was going to ask “Does it look like the vehicle is tumbling out of control?”, but decided not to because I remembered the dogleg maneuver needed to get to SSO.

Absolutely thought "that doesn't look right" after booster sep. Stage reminded me of watching a F9 Booster dropping back after entry burn.

But also didn't say anything! ;D

Images of IBUKI-2 Solar Array Deployment

The reception of telemetry data from JAXA's IBUKI-2 satellite was made at 15:22 p.m. at the Troll Satellite Station, Antarctica, confirming that the satellite's solar arrays were deployed.

October 30, 2018 (JST)

JAXA received telemetry data from IBUKI-2(GOSAT-2)*1, confirming that the satellite attitude control system had transitioned to a steady state. Current status of the IBUKI-2 satellite is stable.
Subsequently, the following procedure occurred - power generation that supports the satellites' operation by the deployed solar array wings, ground communications and sound attitude control that maintains those operations. Combined by the completion
of the series of other operations, such as powering up of the bus and mission equipment, IBUKI-2 has been able to sustain itself in orbit. This concludes the critical operations phase*2.

IBUKI-2 will move on to the next operations phase*3, where the functions of the satellite's onboard apparatus will be examined approximately in the next 2.5-month period.

JAXA conveys deep appreciation for the support by all for the satellite's launch and tracking.

*1: The Greenhouse gases Observing SATellite-2 "IBUKI-2" (GOSAT-2) is co-developed by three organizations: Japanese Ministry of Environment, National Institute of Environmental Studies, Japan and JAXA.

*2: Critical operations phase: the phase that follows satellite's separation from a launch vehicle. In this phase, solar arrays are deployed and the onboard instruments are turned on for the satellite's regular operations. The critical operations phase
concludes when the control mode begins for the satellite's nominal operation.

*3: Next operations phase: during this phase, the entire satellite, its observation/mission sensors and other onboard equipment are scrutinized.

Thank you for the launch thread coverage, Steven and Zach!

Thank you for the explanation of the visual manifestation of the dogleg maneuver.  I, too, was wondering, as it happened, what was going on.

I also enjoyed the JAXA background music.

Congratulations to the entire launch campaign team!

Follow-up:
Debris was from GOSAT-2 H2A's upper stage (F40), which broke up about a year and a half ago after undergoing a partial deorbit, and had an almost head-on trajectory wrt ISS.

https://twitter.com/planet4589/status/1308555063690919936
Quote from: jcm
The debris object that ISS avoided is now available on SpaceTrack as 2018-084CQ, 46477, from the breakup of Japan's H-2A F40 rocket stage. At 2221:07 UTC it passed within a few km [of the position ISS would have been at if it hadn't maneuvered] at a relative velocity of 14.6 km/s, 422 km over the Pitcairn Is in the S Pacific.
