On a tangent: Mitsubishi Electric unveils new complex for construction of satellites (Asahi Shimbun)

KAMAKURA, Kanagawa Prefecture--Mitsubishi Electric Corp. unveiled its new 3 billion yen ($30 million) facility for the construction of satellites at its Kamakura Works here on April 12.

Scheduled to be fully operational in late May, the satellite construction complex is expected to double Mitsubishi Electric's combined production capacity to eight units a year as it expects to win more orders from overseas.

"We plan to raise sales of the space business to 150 billion yen in 2020 from the current 70 billion yen by winning two orders from overseas annually," said Masamitsu Okamura, who heads the Kamakura Works.

The six-story facility, with a total floor space of 7,817 square meters, is capable of producing four units simultaneously, according to the company.

The heart of the complex is the "clean room," a section about 30 meters square and 19 meters tall, where temperature and humidity is controlled and fine dust is shut out.

Mitsubishi Electric is the nation's leader in the production of satellites.

The domestic market for satellites--four to five units a year--is dominated by Mitsubishi Electric and NEC Corp.

Mitsubishi Electric became the first Japanese manufacturer to build a commercial satellite for a foreign client after receiving an order from a Singaporean business in 2008.

The global market for satellites is estimated at around 1 trillion yen annually. The sum is the equivalent of 20 to 25 satellites.

Interesting concept, "Gravity" came up my mind at once, too ! ;)
How would the orbit and flightpath of this satellite be effected, if it catches a sizeable piece
of junk ? Probably it would need considerably more powerful engines andmore fuel,than a
standard satellite of that weight?

Well, a solar sail, which is hit by a piece of debris or a meteor, probably will just suffer a whole, relative
to the size of that piece. But the intention of that net is, to catch that piece and so, I think, the kinetic
energy would have to be compensated for by the satellite, Quite a task, if it is a larger piece !

Surely the key here is the inertia of the junk versus the inertia of the satellite and net. This can be managed by matching velocities, i.e. this would work best when targeted against specific pieces of junk, with known velocities. Even LEO is too big a volume to just go randomly trolling for junk.

One giant leap for Pocari Sweat--sports drink set for 2015 moon landing

May 16, 2014

By TOMOYUKI IZAWA/ Staff Writer



When future astronauts walk on the moon it won't be Tang they will be drinking to quench their lunar thirsts, if the makers of Pocari Sweat have anything to say about it.

Otsuka Pharmaceutical Co. announced May 15 that its popular sports drink with the unusual name will be hitching a ride on a rocket bound for the moon in October 2015.

Otsuka Pharmaceutical's Pocari Sweat division came up with the idea after they heard reports by U.S. scientists last year claiming that the moon likely has sources of water.

A canister of powdered Pocari Sweat concentrate made to resemble a can of the sports drink sold in vending machines will be left on the lunar surface, and all the future Neil Armstrongs have to do is add water, according to company officials.

The canister will be made of titanium to withstand the extreme temperatures of the lunar surface, which can hit 110 degrees during the day and plummet as low as minus 180 degrees at night. A plaque with the hopes and wishes of 38,000 children engraved on it will accompany the canister of Pocari Sweat.

The rocket, sponsored by a private company, will be launched from Florida and make the 384,400-kilometer trip to the moon in about four and a half days. A lunar lander will transport the canister to the moon's surface.

"We want our use of the moon to set an example," said an Otsuka Pharmaceutical official, referring to the fact there are no laws or regulations regarding the use of the lunar surface. "We will not damage the lunar environment."

Otsuka Pharmaceutical has been a forerunner in the field of space advertising, shooting the world's first "space commercial" at the International Space Station in 2001.

The Yomiuri Shimbun

The Defense Ministry has come up with a basic plan for the use of space for national security purposes that features the establishment of a special unit tasked with monitoring space debris and keeping tabs on other countries’ antisatellite weapons.

After the government incorporated “Use of Outer Space” into its National Security Strategy, compiled late last year, the ministry began revising the Basic Guidelines for Space Development and Use of Space that were compiled in 2009.

Under the new policy, unveiled to the Liberal Democratic Party’s National Defense Division on Thursday, the ministry stressed the importance of a mission to keep track of space debris, such as fragments of satellites and rockets no longer in use, to protect communications satellites and other devices directly related to Self-Defense Forces activities.

As collisions with space debris could cause serious damage to satellites, the ministry plans to launch a unit within the ministry or the SDF to work closely with the Japan Aerospace Exploration Agency (JAXA), which currently monitors space debris with a radar system deployed in Okayama Prefecture, as well as with U.S. forces.

The ministry also plans to test infrared sensors for the first time in space to detect signs of ballistic missile launches by North Korea. With the sensors to be installed on a cutting-edge optical satellite, the test is intended to check the sensor’s ability to detect the heat from missile launches.

Govt eyes development of expendable satellite

The government will start full-fledged discussions in next fiscal year on the development of an expendable small observation satellite, which could be launched immediately in such eventualities as a natural disaster or a military emergency, it has been learned.

The new satellite could be used for rescue and information-gathering activities, according to government sources.

The envisaged satellite is referred to as an operationally responsive small satellite. Its development is included as a subject for discussion in a draft of the Basic Plan on Space Policy, which was released in autumn by the government’s Committee on National Space Policy.

A preassembled satellite, measuring 70 centimeters in length, width and height, would be launched with a camera and other equipment in case of emergency. It weighs from 100 kilograms to 150 kilograms.

The satellite would fly at a relatively low altitude of 200 kilometers to 300 kilometers, half that of an ordinary observation satellite, to observe a targeted area in detail. The satellite would burn up upon reentering the atmosphere about a week after launch.

The government plans to establish a working group jointly with the Cabinet Office, the Education, Culture, Sports, Science and Technology Ministry and the Defense Ministry.

Currently, Japan possesses the Daichi-2 Earth observation satellite and information-gathering satellites, but does not have enough satellites to observe specific areas thoroughly. The government will discuss using expendable small satellites to cover the shortage.

Japanese team wins 'milestone award' for lunar rover development


January 28, 2015


By RYUTA KOIKE/ Staff Writer



A Japanese private-sector team was one of five entries to receive a special prize to develop an unmanned lunar rover by sponsor Google Inc.

The Hakuto team, the lone Japanese entry, announced Jan. 27 that it received the "milestone award" for $500,000 (60 million yen) in the multimillion-dollar Google Lunar XPRIZE competition.

The funds will go toward further developing and refining the rover, which is required to be launched to the moon by the end of 2016.

The Hakuto lunar rover is being developed by a team led by Kazuya Yoshida, a professor of aerospace engineering at Tohoku University who helped create the Hayabusa asteroid probe.

The team of researchers and venture-capital entrepreneurs earned the milestone award after the Hakuto rover passed mobility tests held between November and December.

The milestone awards are part of $30 million in total prize money being offered by Google.

Eighteen teams from various nations are taking part in the competition.

Each team must develop its rover for launch by the end of 2016. Once the rover lands on the lunar surface, it must travel more than 500 meters and transmit video images back to Earth.

Apparently the work on a follow-on suborbital rocket to previous RVT-9 VTOL rocket work is moving along well. Recently had 100 firings of their new LOx/LH2 engine without overhaul.

Apparently the ISAS Inatani lab is now confident enough in their work to start tweeting about it too.

http://twitter.com/spacelark_jaxa


It just might be be a mockingbird/bricklifter class SSTO machine, though lacking sufficient reentry heat shielding. Inatani seems confident they will complete the new vehicle, which ought to provide sufficient experience, along with SpaceX's first stage landing success, to get JAXA off its ass to build a true bricklifter class SSTO. Japan is getting antsy about assured space access, along with the above mentioned operationally responsive satellite work needing a matching launcher. It would be kinda funny that "son of DC-X" came from the other side of the pacific, considering the Clipper name heritage.

The H-2B, which is designed to be launched once a year, is 56.6 meters high and weighs 531 tons, making it the largest rocket in the history of Japanese space development.

The cargo vehicle, weighing in at 4.6 tons, is carrying such supplies as food and other daily necessities, a water tank for feeding killifish and a device for releasing small satellites into space, the space exploration agency said.

The H-2B was jointly developed by JAXA and Mitsubishi Heavy for the purpose of carrying the Kounotori, which has a payload capacity of 16.5 tons. The rocket is twice as effective as H-2A rockets at launching satellites into orbit, JAXA said.

JAXA plans to develop a "homing version" of the Kounotori that will be used to return ISS equipment to Earth, JAXA officials said.

Like the H-2A, the country's mainstay rocket, the H-2B's first and second components are propelled through the reaction of liquefied hydrogen and liquefied oxygen.

Following the decommissioning last year of U.S. space shuttles, the Kounotori has been gaining international attention as a means of transporting large payloads into space, JAXA said.

nice 28 years after DC-X and 7 years after SpaceX grasshopper
but faster as ESA CALLISTO that should fly in two years
In all fairness, in the wake of the DC-X Japan already tested a series of VTVL rocket demonstrators in the Reusable Vehicle Testing (RVT) program from 1998 until 2003, see for example https://en.wikipedia.org/wiki/Reusable_Vehicle_Testing, so it's not exactly a brand new concept for them...

Satellites aimed at preventing space collisions under review (The Yomiuri Shimbun)

The government is considering introducing space situational awareness (SSA) satellites to protect Japanese satellites from collisions with space debris and interference by satellites operated by other nations, The Yomiuri Shimbun has learned.

According to several government sources, launch of the SSA satellites, which are capable of monitoring an area in space, is being planned for a period from fiscal 2024 to fiscal 2028.

The government is making arrangements to have the National Defense Program Guidelines, the basic framework for the nation’s defense policy that will be revised at the end of this year, mention that “the entire government will be involved in efforts to significantly strengthen space situational awareness capabilities.”

SSA satellites monitor the movement of suspicious satellites, as well as space debris circling Earth at high speed — fragments of rockets, satellites that no longer operate, and other objects. If the SSA satellite recognizes a Japanese satellite is in danger, it will notify operators on the ground who can instruct the satellite to change its orbit and avoid a collision.

The government estimates each SSA satellite will cost about ¥15 billion, with each rocket launch costing from ¥5 billion to ¥10 billion, according to the sources.

Behind the Scenes / Company serious about launching rockets (The Japan News / The Yomiuri Shimbun)

The name of Canon Electronics has only been heard in space development circles in the last few years. The company was said to have been working on small satellites and small rockets, with the aim of getting into the space industry, but these claims were greeted with incredulity.

Last summer, interest in the company suddenly perked up. Canon Electronics established a planning company to get a foothold in the overall space business.

Four companies joined together to co-found the planning company: IHI Aerospace Co., which manufactured the small Epsilon rocket; Shimizu Corp.; the Development Bank of Japan; and Canon Electronics, which provided 70 percent of the funding.

Significant progress was made on July 2 with the upgrade of the planning company to an operating company called Space One Co. The company then announced it would start rocket launching services in fiscal 2021, with the goal of achieving 20 launches per year by the mid-2020s.

http://www.spacedaily.com/reports/Japan_firm_signs_with_SpaceX_for_lunar_missions_999.html
A Japanese start-up is to send spacecraft to the moon in a deal signed with Elon Musk's SpaceX, the Tokyo-based firm said Wednesday.

Private lunar exploration company ispace said it would blast a lander and rovers towards the moon on a SpaceX rocket on two separate missions.

The spaceware will first orbit the moon in mid-2020, followed by a moon landing attempt set for mid-2021.

It comes a week after SpaceX confirmed Japanese billionaire Yusaku Maezawa will be the first man to fly around the moon on a SpaceX rocket as early as 2023.

"We share the vision with SpaceX of enabling humans to live in space, so we're very glad they will join us in this first step of our journey," ispace CEO Takeshi Hakamada said in a statement.

Hakamada also told reporters the company chose SpaceX as it is "highly credible" and "capable".

SpaceX President Gwynne Shotwell said in a statement that the company is "proud to have been selected by ispace to launch their first lunar missions".

Hakamada said he could not reveal costs for lunar programmes.

The company has already collected nearly $95 million from investors.

ispace, which now has more than 60 employees, competed as one of five finalists in the Google Lunar XPrize, which offered $30 million in prizes but ended with no winner.

ANA and Marubeni join to build spaceport in Japan (Nikkei Asian Review)

TOKYO -- All Nippon Airways operator ANA Holdings and trading house Marubeni will set up a spaceport in Japan as early as 2021, Nikkei has learned.

The launch site, equivalent to a seaport for ships or an airport for aircraft, will be for private space travel, and feature 3-km runways for craft that take off horizontally like airplanes.

There are already around 10 spaceports in the U.S. for commercial use, some built for the purpose and others converted from airports. The Japanese corporate alliance aims to secure a foothold in the international space-business race by building Asia's first space travel hub.
