Launch of Global Changing Observation Mission - Climate "SHIKISAI" (GCOM-C)  and Super Low Altitude Test Satellite TSUBAME" (SLATS) aboard H-IIA Vehicle No. 37

October 27, 2017 (JST)

Mitsubishi Heavy Industries, Ltd.
National Research and Development Agency
Japan Aerospace Exploration Agency (JAXA)

Mitsubishi Heavy Industries, Ltd. (MHI) and the Japan Aerospace Exploration Agency (JAXA) are pleased to announce the launch schedule for Global Changing Observation Mission - Climate "SHIKISAI" (GCOM-C) and Super Low Altitude Test Satellite "TSUBAME" (SLATS) by H-IIA launch vehicle No. 37.

Scheduled date of Launch : December 23 (Sat.), 2017
Launch time                    : 10:26:22 a.m. through 10:48:22 a.m. (JST)
Reserved Launch period   : December 24 (Sun.), 2017 through January 31 (Wed.), 2018
Launch site                     : Yoshinobu Launch Complex at the tanegashima Space Center 

H-IIA Launch vehicle No. 37 incorporates JAXA's newly developed outcome to insert SHIKISAI and TSUBAME into different orbit altitude respectively. It will expand opportunities of multiple satellite launch and take full advantage of the capability of HIIA.

Online Galactic Penguin SST

Note that as of right now, the start of the launch window for this falls on the exact same minute (!!!) as for the launch of Falcon 9/Iridium NEXT Flight 4 on the opposite side of the Pacific. IF (a very big one) this ultimately happens the two will be <=37 seconds apart, which will be an all time record:o

I very much doubt both will manage to hold on schedule to that point with 57 days left but.....one never knows for sure when will we need split screens.  ;) ;)

Technical info on GCOM-C can be found here, and for SLATS here.

Not a straight line path!

Yes, a good example of yaw steering/dog-leg maneuver, so as to achieve the desired sun-synchronous orbit when the launch azimuth for a direct flight would take the vehicle over another sovereign state's airspace (in this case, the Philippines), or put a drop zone onto land, or another sovereign state's territory.

(For the curious, "dog-leg" is an idiom in English.  We have dog-legged roads, dog-legged fairways on golf courses, etc.--slightly, but not severely bent.

Why dog-leg instead of cat-leg or horse-leg (or any appropriate mammal leg), I don't know.  One of the perks of being "man's best friend?")

T-9 minutes. This H-IIA 202 launch vehicle will take about 108 minutes to complete this dual-payload mission.

The first satellite to be deployed, GCOM-C, will study the Earth's carbon cycle from a 798-kilometer sun-synchronous orbit. As for the second satellite, SLATS, it's powered by an ion engine and will show how certain satellites can operate in extremely low orbits. SLATS will be placed in a 450 by 643 kilometer orbit, but will lower its altitude to 180 by 268 kilometers in the near future.

Welcome back to the second part of tonight's coverage of the 37th H-IIA mission.

We're about five minutes away from the first restart of the second stage engine, whose second of three burns will last eight seconds.

You can also tune in to the Iridium-NEXT F4 webcast as that other rocket's second stage will restart momentarily and begin releasing its payloads 12 seconds after the LE-5B engine shuts down.

We're about 73 minutes into the flight. Coast phase appears to be nominal thus far.

As for the Iridium-NEXT F4 mission, that's pretty much over as those satellites will have finished their deployment sequence by now.

Again, the next milestone will be the third burn of the LE-5B engine, which will last 68 seconds. That should occur in about a half-hour.

The commentary volume on the YouTube web cast JAXA channel seems to be turned WAY down.

I heard the calls, faintly, for burn start and end.

Volume UP for S/C deploy!

Followed by the immediate end of the commentary from mission control center.

They're promising video footage of the (second) satellite deploy.

Congratulations to JAXA for successfully launching the Shikisai global change monitor and the SLATS low altitude experimental satellite! I thought the webcast had some cool animations and features about Shikisai’s science as well, though my Japanese is non existent so I couldn’t follow along as well as a Japanese speaker could. (I did appreciate the snippets in English though and the graphics were easy to understand).
I'll even excitedly look forward to "flags and footprints" and suborbital missions. Just fly...somewhere.

Completion of Critical Operations Phase, SHIKISAI and TSUBAME
December 24, 2017 (JST)

JAXA received telemetry data from SHIKISAI and TSUBAME, confirming that their satellite attitude control system had transitioned to the steady state. Current status of both satellites 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, the satellites have entered the state where they can be sustained in orbit. This concludes their critical operations phase*ą.

SHIKISAI and TSUBAME will move on to the next operations phase*˛, where the functions of the satellites’ onboard apparatus will be examined approximately in the next three-month period.

JAXA conveys deep appreciation for the support by all for the satellites’ launch and tracking.

*ą Critical operations phase: the phase that follows satellite’s separation from a launch vehicle, solar array deployment, and powering up of instruments for the satellite’s regular operations. The critical operations phase comes to an end at the start of the satellite’s control mode for nominal operation.

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