Looks like JAXA is penciling in the SS-520 reflight for March 2017 2018 according to NHK/JAXA press conference

http://www3.nhk.or.jp/news/html/20170407/k10010940591000.html


Rumor mill says the rocket will be called SS-520-5, flying a payload called TRICOM-1R (likely the backup unit for TRICOM-1).


EDIT yeah, meant 2018...

I think that's "Spring 2018" if my crude Japanese didn't fail me. ;)

Oh JAXA seems to be pushing hard to get the reflight sooner than I thought! They just scheduled the launch on Christmas Day @ 01:00 - 05:15 UTC.  :o

Epsilon delays creating an opening plus they don't want to be upstaged by Interstellar/Horie-mon...

Rescheduling of SS-520 Experiment with Microsatellite on board
December 8, 2017 (JST)
National Research and Development Agency
Japan Aerospace Exploration Agency (JAXA)

JAXA has rescheduled the SS-520 experimental launch with a microsatellite on board. This rescheduling has resulted from the updates of the third Epsilon launch operations which will also take place at the JAXA Uchinoura Space center. Refer to the following details;

Experiment Period : December 28, 2017 through February 12, 2018 (including the reserved period)
Location                : The JAXA Uchinoura Space Center, Kimotsuki-cho, Kimotsuki-gun, Kagoshima, Japan
Planned Time        : Approximately 12:30 p.m. through 2:15 p.m., December 28, 2017 (Japan Standard Time)*

In the event of launch delay due to inclement weather and other reason, the updates will come out promptly.

*The time of launch during this period will vary.

We will have live broadcast from JAXA this time:

....and the launch has been postponed.

SS-520 No. 5 Launch Postponement
December 26, 2017 (JST)

National Research and Development Agency
Japan Aerospace Exploration Agency (JAXA)

JAXA has postponed the launch experiment of the microsatellite aboard SS-520 No. 5, due to a malfunction found in the launch vehicle component. The SS-520 No. 5 launch experiment was originally scheduled for December 28, 2017.

Schedule update will be available once complete.

NET mid of January. I think after the launch of Epsilon rocket.

The problem is N2 tank pressure sensor's trouble. The N2 tank is used for ram-line control.

Not just Rhumb Line attitude control but the whole TVC system. Rumor mill says it's going to take a while to swap the sensor, pushing NET into February towards the back end of the window. NET will also be after Epsilon launch, and with the current Epsilon delays so far, the odds are not good for on-time launch, pushing this launch back farther due to shared assets.

Which is a problem, because if they can't launch within the window, a new window apparently won't open until fall or later, due to space traffic/tracking asset/other launch concerns.

new date per launch livestreams (NVS) on youtube is 30 January 2018 at 3pm (not sure about the time zone youtube was displaying).

Here's the link.



YouTube shows your local time. If NVS is correct, the broadcast starts at 03:00 UTC 31 January or 12:00 local. Launch should be at 12:30 local. I suspect that NVS just adjusted their clock to the end of month. Their website doesn't show a new date yet.

New rumor details regarding the pressure sensor. Apparently the sensor failure exposed a QC management issue that is having knockon effects, and that the same sensor may be also used by Epsilon, which could reach back to bite everyone, because if Epsilon has another delay, that could push this launch straight out of the window.

An interesting rumor is that fishing cooperatives usually limited JAXA to launch windows only until the end of January, but Canon Electronics Inc. exerted some kind of corporate pressure to be granted an extension.

Rumor mill says they only have a real chance on 2/3 or 2/7 due to weather forecast and other factors, otherwise they will exceed their allotted window to 2/12.

The launch window has been refined to 05:03 - 05:13 UTC. Launch site weather forecasts for February 3 is however marginal.....

Does anybody know if the launch site safety document (which usually includes the launch profile and timeline) is available for this one?
