Post by: Asteroza on 04/07/2017 09:54 am
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 (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...

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

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.

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.

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.

Second stage ignition is at T+3 minutes, about 2.5 minutes after first stage burnout! Second stage ignition is also at 89 km downrange and 179 altitude. That's a line of site distance of 200 km. Might be a little hard to see!

Apparently the third stage does have a GPS terminal which links to the ground via Iridium satellites, but full confirmation will have to wait until after the cubesat completes its first orbit.

William's article updated to where we are...that it launched but we have no idea if it was successful.

https://www.nasaspaceflight.com/2018/02/japanese-rocket-record-borbital-launch/
William mentions the Japanese Lambda-4S rockets, the last of which (and the only successful one) launched almost exactly 48 years ago. What's interesting is that the low-mass record that this rocket is trying to break is held by that same Lambda-4S.

Not so good news. Not 100% sure this means the launch was a failure.

And hopefully it also means they're going to upload a clean version ("recorded locally") of the launch video.

It has been confirmed that the 2nd stage ignition command was sent this time and the 2nd stage DID ignite!

Next update will come in 2 hours time.

On February 3 (Sat) 14:03, a demonstration experiment of the ultra-small satellite launch was conducted by SS-520 5 from the Uchinoura Space Observatory.
The SS-520 5 was flown as planned, and after the experiment was carried out, the ultra-Small satellite Tricom-1r (Tri-com One Earl) was separated and the orbit was succeeded."

If I get it right, the satellite's nickname is "Tasuki" (たすき)

Congratulations to JAXA and all involved.

Some time ago I asked in another thread about the smallest rocket that could launch a satellite.  Now I have my answer!

Rumor mill says TRICOM-1R sent at least one full iridium transmission. Transmission indicated 3rd stage separation, but higher than expected tumbling. This tumbling appears to be interfering with command reception. Which is a problem, as it may take 2 months or more to settle down the tumbling, but the expected orbital lifetime is around 5 months...

TRICOM-1R apparently is now accepting some commands, and they were apparently able to trigger an image capture and downlink it.
