For this reason, the Japan aerospace exploration agency (JAXA) recently announced its 25-year plan to build the world first 1-gigawatt power plant in space.

Here are thoughts a few on the massive implications of this JAXA announcement. Beam Me Down Scotty

here is JAXA 25-year plan: BASIC RESEARCH PHASE (2014020) 2014 Demonstration on the ground 2017 1-kw satellite experiment DEVELOPMENT PHASE (2021030) 2021 100-kw satellite experiment 2024

Mastering Six Critical Disciplines The JAXA power station is estimated to weigh more than 10,000 metric tons and when fully deployed, stretch several miles across.

JAXA will have to demonstrate mastery of six critical disciplines: Wireless power transmission Space transportation Construction of large structures in orbit Satellite attitude and orbit control Space-based power generation Power management Of these six challenges,

So that precisely where JAXA has focused much of its research. Wireless power transmission has been the subject of conspiracy theories and legends ever since Nikola Tesla experiments at the end of the 19th century.

Optimal Satellite Design Two Approaches JAXA researchers are working on two different approaches. The first one involves a huge square panel (measuring over 1 mile per side) that is covered with photovoltaic receptors on the top and transmission antennas on the bottom.

JAXA has come up with another more sophisticated approach that solves the solar collection problem by employing two huge reflective mirrors.

) Meanwhile, the Japanese space agency JAXA will get#22.9#billion to refurbish its facilities and to speed up development of ALOS-2,

Next month the Japanese space agency JAXA will pilot its electrodynamic tether for the first time. It is one of many possible solutions that have been proposed to deal with space debris (see Catch'em drag'em blast'em.

and the pieces would collide with each other resulting in more and more debris. To build its debris-catching net JAXA brought in Nitto Seimo a company that specialises in fishing equipment Unlike a net you would use in the ocean this one is a 700-metre-long mesh of aluminium

JAXA thinks the net's main advantage is its simplicity#it's lightweight and doesn't require any propellant to move.

or micrometeoroids says a JAXA spokesperson. Not everyone is convinced of the idea. A net isn't necessarily the best option to collect debris says Hugh Lewis an aerospace engineer at the University of Southampton UK.

and evolution of the moon is to know those of Earth says Tatsuaki Hashimoto of the Japan aerospace exploration agency the lead scientist for a proposed lunar rover called SELENE-2. The moon is thought to have coalesced from the debris of an impact between a Mars-sized world and Earth

JAXA today cancelled the planned launch of Epsilon due to an abnormality detected 19 seconds before the planned lift off at 1. 45 pm local time.

Extreme UV is a range of light suitable for observing planetary atmospheres says Shujiro Sawai of the Japan aerospace exploration agency (JAXA.

The Japan aerospace exploration agency sent the first of its new generation of launch vehicles into orbit carrying a telescope that will observe the atmospheres of Venus Mars and Jupiter.

Japan's space program JAXA developed both its Epsilon Launch vehicle and the small satellite carrying the planet-viewing telescope

JAXA reported Saturday's launch went fine and that the satellite now in orbit is in good health.

In Asia, Japan aerospace exploration agency (Jaxa) is also working on a hypersonic airliner called Hytex intended to cross the Pacific ocean in two hours at speeds of Mach 5. Both Lapcat-II

and Jaxa are part of a hypersonic knowledge-transfer project between Europe and Japan called Hikari.

says Hideyuki Taguchi, leader of Jaxa hypersonic airplane research. Hunger for hydrogen But, deriving hydrogen efficiently is one main factor for high operating costs.

The Jaxa project has studied the potential market for hypersonic airliners travelling at Mach 5 and found a 100-passenger aircraft flying two round trips per day is realistic based on market research.

However, the scenario has changed with the launch of the final piece of the Global Precipitation Measurement (GPM) mission by NASA and the Japan aerospace exploration agency.
