ASTRO-H successfully launched and named "Hitomi"

H-IIA F30 with the "ASTRO-H" onboard launched at 5:45 p.m. on Feb 17, 2016 (JST) from the Tanegashima Space Center. The rocket flew smoothly, and, at about 14 minutes after liftoff, "ASTRO-H" was separated from the H-IIA F30.
ASTRO-H is the eye to study the hot and energetic universe. Therefore we name ASTRO-H, "Hitomi". The word "Hitomi".generally means "eye", and specifically the pupil, or entrance window of the eye – the aperture!

The key goal of the engine program is to build an unusually slim turbofan. The low frontal area and the modest bypass ratio evident in drawings would both promote the ability to fly supersonically without afterburner. So would the generous thrust, although 33,000 lb. must be the afterburning rating; the maximum dry output is unknown.

Researchers are aiming to achieve the highest possible temperature at the inlet to the high-pressure turbine, the ministry says in its budget request. They can already achieve 1,600C (2,900F) but want to go higher during the study program, while also reducing engine weight, it says. Mitsubishi Heavy said last year it had achieved a 1,600C turbine inlet temperature, the highest ever, for an electricity-generating engine to be installed in a power station.

Previously disclosed elements of the Japanese engine research include single-crystal turbine rotor blades, stator blades made of ceramic matrix composite (a ceramic reinforced with carbon fiber) and an advanced combustor.

That's a neat japanese engine is that what they use on the new japanese stealth fighter?

i must say i have always been a fan of japan and their neatness , also the koreans , as opposed to know some of their neighbors , i had an ADSL modem made in japan and i was always astounished how neat it was

New satellite would send fastest signals

The government plans to start developing a communications satellite that is capable of sending high-capacity, high-speed communications, such as for Internet access, from space in fiscal 2016. By utilizing Japan’s technology, the government aims to increase its international competitiveness in the satellite market, in which Japan is behind Western countries.

Working expenses of the Education, Culture, Sports, Science and Technology Ministry and the Internal Affairs and Communications Ministry are expected to total between ¥30 billion and ¥40 billion.

The planned satellite aims at a communication speed of 100 megabits per second, which is 10 times faster than current domestic satellites and nearly double the speed of overseas satellites.

To realize it, technological innovation regarding solar cell panels and storage batteries to be installed in the satellite will be necessary. The government plans to reduce the weight of the satellite — and the costs of building and launching it — by replacing liquid fuel for purposes such as attitude control with all-electric systems.

Development of the satellite will be carried out by the Japan Aerospace Exploration Agency (JAXA) and domestic companies from which the government will accept applications in the future.

A test version of the new satellite will be launched in fiscal 2021 by the planned H3 rocket, a next-generation large-scale rocket whose development the government is promoting.
