I'm glad someone made a thread about these guys, I was wondering about that rocket nozzle. I've never heard of a nozzle where the entire thing glows white-hot, top to bottom -- what's the deal with it, like what kind of engine bell is that? Is it ablative?

Anyway I love what these guys are doing on a shoestring budget. I'd love to see them get to the level where Masten is.

It's called radiatively cooled nozzle. merlin 1 Vacuum has it. And I think the RD-58MF is supposed to have a composite one. You basically use a material that can tolerate the heat and put some serious thermal barrier upstream.

Per their site, most of their engines are ablative, but it's quite common for these things to look a lot whiter in photos and video than they would in person.

Welcome to the forum, and thanks for dropping by !

Are you able to share some updates with us here, as well ? For example, what major upcoming milestones is the company looking forward to ?

Also, i've tried to become a member of your fanclub on Campfire, but unfortunately Japanese translation didnt get me far enough. Any chance you guys could start a Patreon account in parallel ?

Hi

I'm from this company too ;)

Our next mile stone is to launch sounding rocket MOMO.

Currently we are working on manufacturing the very first MOMO.
Next experiment will be our final full duration static fire test for MOMO which will be held soon.

On top of that, we are working on orbital rocket.
We are doing lots of calculations so that our orbital rocket will properly deliver satellites.
Our programs are uploaded here https://github.com/istellartech.
Its constantly been updated.

Experimental wise, we started to work on critical technology for orbital rocket, turbo pumps.
We have already done few experimental static fire test of gas generator to get a better understanding.

We thought about starting a cloud funding in kickstarter but unfortunately, we don't have a US bank account.

Kickstarter has preannounced they are entering the japanese market (estimated fall 2017), which I assume means they will accept japanese companies with japanese bank accounts.

Would be interesting as a "launch" campaign partner to be one of the first all japanese kickstarter campaigns.

TOKYO -- Interstellar Technologies will attempt to launch a privately developed rocket into space on July 29, aiming to become the first Japanese company to do so successfully.

The venture announced plans Thursday to launch its first rocket, the Momo, from the northern island of Hokkaido in a window that starts at 10:20 a.m. JST.

Interesting.  Historically companies that have stayed in the business of making sounding rockets have converged on the solid fuel design, but your pressure fed LOX/Ethanol seems only a little more complex, but is safer and should have higher performance. It also seems to have a lower g rating, needing less ruggedly built hardware.

I look forward to seeing many projects starting their lives with a first flight on this rocket.

Quote
The rocket was scheduled to be launched at around 6:30 a.m., but since a number of troubles were found in valves of liquid oxygen tank etc, work continued with the aim of launch until 0:30 pm.

However, it was decided that safety could not be secured because a ship entered the warning area on the sea, and it was decided to aim the launch after 3:45 pm.

Translation is not great but I think the meaning is clear enough. Flew for about 80s so that’s a decent amount of time before telemetry was lost. Hopefully they have a lot of data on how well it performed to that point.

Indeed. Let's remember historically ELV's have a 50/50 chance of a successful first flight and the first 3 F1 flights were not successful.

It looked like lousy weather for a launch, but maybe it looked worse than it was IE bad visibility but light winds and no lightning, which are the real trouble makers in a launch.

On the upside isn't 80secs close to stage separation?  For a first flight that should be quite useful, provided they can identify the root cause. Also the translation implies the vehicle self terminated, without a range safety receiver on board. That may sound trivial but those are specialist devices and quite expensive for what they do.   Not needing to carry one disproportionately lowers the fixed costs of a small vehicle, which is a good thing if you want to make this vehicle profitable.

I hope they assess the data and use it to drive the next copy of the vehicle.

Some articles out now, no new detail

http://www.japantimes.co.jp/news/2017/07/30/business/tech/launch-private-rocket-backed-horie-fails-off-hokkaido/

Quote
The launch of what would have been Japan’s first privately developed rocket to reach outer space failed Sunday off Hokkaido after telemetry was lost, forcing it to be aborted, the Hokkaido-based developer said.

Officials from Interstellar Technologies Inc., founded by former Livedoor Co. President Takafumi Horie, said the 10-meter-long Momo rocket was aborted after communications with the rocket’s telemetry system failed about 80 seconds after liftoff. The rocket was launched from the town of Taiki, on the island’s south coast.

The rocket fell into the Pacific Ocean about 8 km offshore after its engine was halted, they said.

So engine shutdown was by radio command rather than on board software?
It also suggests engine cutoff shut off power, which seems odd, like on board power was being generated from the engine, rather than from a battery. 

TBH this sounds like quite a good idea, depending on the trade off between generator mass and battery mass, with a small battery to run between switching to internal power and engine start.

The flight was terminated because the rocket stopped transmitting so onboard footage and GNC data was lost shortly before ground issued thrust and flight termination.  Your theory is unlikely based on the available data on the rocket. Also the receiver on the rocket worked because it was a separate antenna and box rather than combined transceiver unit like most sounding rockets these days.

That bending could be just a video artefact. However, this might show the camera being ripped off, perhaps due to the vehicle losing control. The vehicle does appear to be rolling, probably not a good thing in a liquid fuelled rocket, as the propellant would centrifuge to the walls, changing the centre of gravity and possibly sending the vehicle into a flat spin.

Hi guys. :)

Thank you for tracking us!

As everyone here knows, we lost a signal after 66 second of flight.
In the news, it states we sent an abort signal and we did.
But most probably before we sent the command, it would have been shut down by it self.

We are still under investigation of the root cause of this event.
We have some idea on what has happend but still under discussion.
Also, the team are exhausted from the launch schedule which we used up all the windows.
 
Anyway, we got a valuable data from the rocket which can lead to 2nd MOMO.
We are planning to launch it again by end of this year with the improvement and hopefully, the next launch will be in outer space. 8)

Stay tuned!

It's interesting how japanese domestic reporting calls it a failure, but US reporting calls it a partial success.

Horie-mon is a bit miffed by Canon Electronics forming a new domestic newspace JV and he wasn't invited. If Interstellar can get a successful reflight in before Canon Electronics and their SS-520 reflight, we may see Horie-mon steal some of the PR thunder here.

Japanese company plans second launch of privately funded sounding rocket this year
by Jeff Foust — August 23, 2017

LOGAN, Utah — A Japanese company whose first sounding rocket launch last month failed to reach space will try again by the end of the year as it continues work on a small launch vehicle.

[…]

Horio said that, once in commercial service, Interstellar will sell launches of Momo for $300,000 each. The company expects to produce one rocket every one to two months.

Published on May 1, 2018

The launch was postponed in order to investigate the cause of nitrogen gas pressure leakage for valve operation which occurred during preparations for the launch of the IST Natsu Natsu rockets' observation rocket 'MOMO' on April 29. It is a pattern to return from the launch point to the hangar. There is adjustment of cause and adjustment of launch timing, the next launch is planned around the summer 2018.

The ship enters the maritime warning zone, and the schedule time is changed to 5:30 while seeing the sailing condition of the ship because it does not go out to the warning zone outside at 5:00 of the originally scheduled launch time.

The poor thing. I appreciate a little kaboomy goodness from spaceflight history, but it's another thing when you're watching a startup and a team that's giving everything they've got so far.

Do try again, gents. SpaceX started the same way you did, and look where they ended up.

I detected a leak on the side of the engine just one second after ignition. I captured two pictures to illustrate the moment. Probably, the engine shutdown was a remotely commanded or it happened because the loss of pressure reducing substantially the pressure drop from the chamber to the line.

Go to 1:28:30 in the video to watch the launch. I feel for the Momo team at this launch failure. Hopefully they'll find out what went wrong, fix the problem and try again. I'm sure the team will learn a lot from this.

What is the first stage engine exactly? There was talk of it using an ablative nozzle, so do hot fire tests require replacing the nozzle?
Title: Re: Interstellar Technologies
Post by: Steven Pietrobon on 07/05/2018 06:36 AM
Not sure if the engine is ablative, but there is certainly no liquid cooling!

Some screen grabs. Looks like a combustion chamber failure.
Title: Re: Interstellar Technologies
Post by: Asteroza on 07/06/2018 12:22 AM
From the height though one might guess a chamber injector header failure since it comes out sideways? Unlikely the top of the combustion chamber came undone though. The nozzle is uncooled, but if the chamber is regen cooled or an expander cycle, then that pipework might be suspect as well.

Interstellar Technologies Continues Works on the Development of Its Own Rocket Despite MOMO-2 Launch Failure

[...]

“We will begin the next launch as soon as we are ready. We were able to launch MOMO-2 within less than a year after MOMO-1. The launch interval of MOMO-3 and MOMO-2 will be shorter,” Inagawa said.
