The Japanese Ministry of education and Science (MEXT) has published a number of documents on the SS-520-4 nanosat launcher. Apparently the fourth SS-520 sounding rocket will be fitted with an additional 3rd stage to put a 4 kg CubeSat called TRICOM-1 into orbit og 180 km x 1500 km x 31°.

I could not figure out, if there is a scheduled launch date, but as the serial number of launcher (SS-520-4)is given, this project appears to be pretty advanced. Perhaps someone with Japanese language skills can figure out more.

The question is how much does LV cost?. $250k is going list price for 3U launch on likes of Rocket labs electron.

If they can do it for <$500k, there would be a market for it.

As it is a one-off demonstration mission with no follow-on flights planned, the launch price is not really relevant.

If I'm reading that diagram correctly, then at 9.54 m length x 0.52 m diameter this would be the smallest orbital launch vehicle ever designed!  It sounds similar in concept to the mothballed Indonesian RPS-420, though that intended to launch up to 50 kg by using side boosters.

Pilot was significantly shorter but slightly wider. Six were launched, plus four suborbital tests, all failed.

The Japanese L-4S was also more or less based on sounding rocket technology, although it had a higher payload than SS-520-4.

How does SS-520-4 compare to SM-3 block2A?
I wouldn't be surprised if Orbital ATK also develops a launcher like this when it proves to be in demand. (Using ASAS boosters (GEM-22/ Oriole is one of them as is the SM-3 Block 1 third stage.
I think launch cost of up to $1mln are acceptable if a Cubesat or Nano Satellite has to be launched at a specific time or to an odd orbit.

What the documents give us about SS-520-4:

Loaded masses 1587 kg stage 1, 325 kg stage 2, 78 kg stage 3,

Not given: size and empty mass of stage 3 in orbit. Thrust of each stage.
Would be great if anyone with JAXA contacts could find these out.

Here is an old, 2009 slide deck that talks about commercialization strategy. Not sure how relevant anymore.

newer version from 2010:
http://mstl.atl.calpoly.edu/~workshop/archive/2010/Summer/04%20-%20Charania%20-%20Nanolauncher.pdf
SpaceWorks Japan subsidiary NanoLauncher LLC of website listed in presentation (http://www.nanolauncher.com/) has since merged with SpaceWorks US rocket subsidiary Generation Orbit.

Per IHI, ISAS, and the presentation both the B0 Boost Motor and the B3 Motor (To be used on SS-520-4) have been fully developed and ground tested in conditions mimicking actual flight. The development and ground testing status of the B4 motor is unknown. Apparently as of the beginning of last year IHI and ISAS are continuing the NS/NL-520 programme for now even though the original company behind it has merged with its US parent company's US subsidiary.

This is the follow on Joint venture: http://www.sei.aero/eng/papers/uploads/archive/SSC11-II-5.pdf

As of right now, there are two or three launch pads at the Uchinoura Space Center. Which one will SS-520-4 take off from?

KAPPA/LAMBDA PAD (31.2523 N, 131.0785 E)
MU/M-V/EPSILON PAD (31.251 N, 131.082 E)
TEMPORARY PAD (31.2527 N, 131.0754 E)

Use Google Maps or Google Earth to search for these pad coordinates.

I do not think so, as the Mu pad is still on its site, although somewhat modified for Epsilon.

Hmmm...

According to http://spacelaunchreport.com/padsites.html (Hat tip, Ed!) there are two pads at Uchinoura.  One is the former M-V pad, now rebuilt for Epsilon.  The other is on the hill above it.

Ed has it labeled as the former Mu pad - perhaps it is a sounding rocket facility instead?

That what Ed has labled "former Mu pad" is the Sounding rocket pad (Lambda, S-310, S-520). This facility has apparently two launchers -  the one sheltered in the concrete structure (used for S-310) and the open air launcher (for S-520 and SS-520). The latter was originally only a concrete pad for a mobile launcher, but has now a firmly installed rail launcher (as seen in the SS-520-4 images)

It may have been built for the NS-520 and NL-520 versions as the rail is long enough to accommodate their lengths.

It was there in 2014 for the S-520-29 launch (image below from the ISAS website)

S-520-27 launched from the mobile launcher close to the position of the new launch rail, which would put the construction some time between December 2012 and August 2014:
http://www.isas.jaxa.jp/j/topics/topics/2013/0720_s-310-42.shtml

S-520-28 also used the mobile launcher, but from within the dome.


I've also found what appear to be the official names for the pads at Uchinoura: the sounding rocket pad (which will be used for this launch) appears to be called the KS Centre, and the Mu/Epsilon complex is called the Mu Centre.

There is no telemetry capability on the third stage, launch success will be confirmed by the satellite signal received 1st AOS at 90 min. after launch. Press conference will be held at 3 hours later.
Third stage has GPS navigation capability, these data are transmitted to the ground station via iridium satellite. But, there is no confirmation for satellite separation.

We'll be glad of the wide-angle shot. She's going to go like a bat out of hell.

An aside, if all goes well the rocket will take four minutes and 13 seconds to reach orbit. I don't know what the record is but that's got to be close. S/C sep is at seven and a half minutes - that final coast is the longest phase of the mission.

Here's the official announcement of the launch scrub.

"The launch of the SS - 520 - 4 aircraft scheduled for January 11 (Wednesday) from the Uchinoura Space Observatory was postponed because the weather did not meet the necessary conditions. I will inform you about the new launch date again."

https://translate.google.com.au/translate?hl=en&sl=ja&u=http://www.isas.jaxa.jp/topics/000795.html&prev=search

Here is the NVS blog who gave us the live feed of the launch attempt.

It seems that the ground lost telemetry tracking and thus the 2nd stage was not commanded to ignite.
The press conference should come within the next hour.

That's what it looked like to me from the launch video. It seems to cut off when the plume was still quite bright, and then nothing. Yeah it was pretty high, but we could still see it going up, and then the plume just suddenly stopped.

Shame, it would've been nice to have gone 2 for 2 today.

January 15 10:30
The world's smallest mini rocket newly developed by the Japan Aerospace Exploration Agency (JAXA) is trying to launch an ultra-small satellite that can be carried by hand at a low cost, at 8:33 am on the 15th, Uchinoura Space in Kagoshima Prefecture Although it was launched from the observatory, because the data indicating the condition of the airframe could not be received in the middle, the second stage rocket was not ignited, the flight was interrupted and the launch failed.

NHK has confirmed that: http://www3.nhk.or.jp/news/html/20170115/k10010840191000.html (they apparently brought in one of their news helicopter in for the launch!)

To clarify - there is a pre-programmed check between 1st stage separation and 2nd stage ignition that the flight is alright. If it is not the 2nd stage ignition command will not be issued.

Here's the tweet from NVS, the team providing video coverage: https://twitter.com/nvslive/status/820443384493973505

Google Translate gives me: "Contact from JAXA: SS-520 Unit 4 "The flight of the first stage of the rocket was done normally, but stopped igniting the second stage motor because the telemeter from the aircraft could not be received while flying. "Tracking was successfully done and confirmed falling into the planned falling area on the southeast of Uchinoura"

Sounds like they watched the stack fall into the no-fly zone, IMO - but that's a guess, not a certainty.  You'd think that if they did they would've been able to tell us about it much earlier.

Sad news :(

For such small rockets it's difficult to get the flight path/altitude in precise control (though acceptable for sounding rocket purposes). Japan's 1st satellite launcher - currently the lightest record holder for a rocket that did put something in orbit - took 5 times to get it right.

The very low cost of the launcher (& usually what's flown on top), however, means that even low success rates may be acceptable for use (though if you don't think you can build more copies of your sat, take a share ride instead). I don't know if Japan's government or other developers on board have more yen to fund some more flights though - it would be a shame if they can't as I wished someone would try flying a nanosat launcher like this under a serious multi-flight program.

First stage was normal. Fell in expected area.
Telemetry stopped after 20 seconds.
Not enough info to proceed with stage 2.
Tracked rocket to ocean near Uchinoura. Investigation continues
Rocket fell in expected first stage impact area.

From what I can gather, lots of questions about the purchase of the telemetry unit from a private company
- presumably different from telem system on earlier SS-520 missions. Keeps saying he doesn't think that's the problem.

Apparently they did receive signal from the falling satellite after it separated (the separation was controlled by a pre-set timer)!

And the 2nd stage ignition check procedure requires ground radio command to start.
It's a radio command control system for old sounding rocket.

That's what it looked like to me from the launch video. It seems to cut off when the plume was still quite bright, and then nothing. Yeah it was pretty high, but we could still see it going up, and then the plume just suddenly stopped.

That's what was supposed to happen. Second stage ignition was supposed to be 2 minutes 28 seconds after first stage burn out (at X+3 minutes) at an altitude of 179 km. I think you'd need to have very good eyes to see that occur! Unfortunately, they lost telemetry 20 seconds after launch, so they couldn't determine if the first stage had performed correctly. Their launch procedure was to send a signal at X+2m 44s to enable second stage ignition if the trajectory was within parameters. Being ultra cautious, they decided not to send the signal as they did not have enough information on the state of the vehicle. I would have sent the signal anyway. :-)

Is it legal to send the signal according to range safety rules?

It's only legal to send the signal if abiding by the range safety rules, but illegal if sending the signal without permission.

SS-520 No. 4 Launch Results

At 8:33 a.m., (Japan Standard Time) January 15, 2017, SS-520 No. 4, JAXA's sounding rocket launched from the Uchinoura Space Center. Through SS-520 No. 4 launch, JAXA sought for research and development of launch vehicles and satellites and the launch
demonstration of TRICOM-1, its onboard nanosat that weighs about 3 kilograms. The launch was part of Japanese government's program for development of launch vehicles and satellites in public-private partnerships. 

The first stage flight of SS-520 No. 4 proceeded according to schedule. Thereafter, however, ground teams could not receive telemetry from the launch vehicle and the call was made to abort the second stage ignition.
JAXA tracked the launch vehicle and confirmed that it fell into the south eastern ocean off the Uchinoura Space Center, within the projected drop area.

Nikkei outs Canon Electronics Inc. as the avionics maker, which connects with the rumor mill that IHI Aerospace were hanging the avionics maker out to dry. JAXA will permit reflight (not originally scheduled, as it was supposed to be a oneoff), which connects with the rumor that Canon Electronics Inc. will be footing the bill for reflight as they seem to heavily desire avionics flight success record for reasons...
