A nice article over at SpaceNews who interviewed the company at the recent Smallsat Conference.
A second Momo rocket will be launched before the end of the year, the cause of failure of the first launch being a loss of telemetry.
Nothing really new besides what we already know, although their orbital rocket plans will switch to new rocket engines and a turbopump feed system, of which I have the shown testing video on here in the past.
A short video (in Japanese) about Interstellar Technologies recent Momo rocket launch.
Updated 2/8/2017 – Added more launch footage
IST successfully launched their Momo sounding rocket, unfortunately, a glitch in the telemetry of the rocket was encountered and the flight was terminated after 66sec of powered flight, the rocket then fell into the ocean safe zone 6.5km off shore.
I have already read talk of Momo2, so hopefully, the team can give it another shot before the year is out.
Interstellar Technologies Inc have been working towards launch of their Momo sounding rocket, this will be the first private rocket launch to go to space from Japan.
Momo is 9.9m long, 0.502m diameter and has a lift off weight of 1000kg. Able to deliver a 20kg payload to 120km in altitude the rocket is powered by a 12kN lox/ethanol pressure fed engine.
You can download the payload user guide here for more information.
The team have had a very active development path, I thoroughly suggest checking out their YouTube channel if this is the first you have heard of them!
Although out of the amateur realm, I have been following the group for some time, so fingers crossed for a successful launch.
The launch is scheduled for July 29th.
Interstellar Technologies have been continuing testing of their LOX/Ethanol engine for their MOMO sub-orbital rocket, most recently pulling off this 120sec burn.
The engine is ablative and uses a graphite nozzle, as you will see it gets pretty hot! Judging by the exhaust plume, it looks to be a nice burn from start to finish.
