unfortunately, the rocket failed to reach its target altitude of 100 km. just over a minute into launch, the ground team lost communications with the rocket. this caused an early shutdown of the engine; estimates are that it only achieved an altitude of around 20 km.if successful, this would have been the first private rocket launched in japan developed by a japanese company. the rocket is about 10 meters high, weighting around a ton. the cost of the launch was jut 50 million yen ($440,000). jaxa has led the country's space efforts until now; their rocket launches cost somewhere between 200 million and 300 million yen ($1.8–$2.7 million).the rocket's partial failure is certainly a disappointment for momo, but at this stage of development, any data is useful. takafumi horie, the japanese entrepreneur behind momo, said on his facebook page, `we were able to get valuable data that could lead to success in the future.` momo's goal is to successfully develop a rocket that can deliver a small satellite to low earth orbit by 2020.
