There are many as yet unsolved questions about liquids with melting points that are too high for containers. If we were able to levitate such liquids, these questions could be answered. JAXA has developed the electrostatic levitation technique. During an experiment using this technique in the synchrotoron radiation facility, a significant discovery was obtained regarding the electronic structure of liquid silicon.

Energy and environmental problems have come to issues that require a global-scale solution. With the concept “clean space communication talking to a far-distant universe,” JAXA is actively engaged in the research and development of: ultra-small, ultra-high-performance sensor and semiconductor integrated circuit; the world’s smallest transceiver with antenna; and an ultra-high-speed wireless communication and energy transmission network.

The excellent capabilities of the X-ray astronomical satellite SUZAKU, launched in 2005, discovered the hottest gas in the universe in the RXJ1347 galaxy cluster. The gas is believed to have been generated by a collision between two large galaxy clusters. SUZAKU captured one moment in evolution where two galaxy clusters’ gravity pulled both together t–o form a single immense celestial body.

Although mankind landed on the lunar surface in the 1960s, the plasma environment of the Moon remains little known. This article introduces the observation results of the low energy charged particle instrument MAP-PACE onboard the lunar-orbiting satellite KAGUYA launched in September 2007. It is expected that the results obtained from this observation will be of great use for a planned Mercury exploration mission.

The temperature of the solar surface is about 6,000 kelvin, yet corona with several million kelvin exists just several thousand km above the surface. The production mechanism for this high-temperature corona remains a mystery. Research on the mystery continues using the most advanced observation instruments onboard the solar observation satellite HINODE launched in 2006.

With the advancement of satellite missions, the accuracy requirements for satellites, their antennae, telescopes, etc., become ever stricter. To respond to these requirements, satellite design must take into account various factors such as: problems related to manufacture on the ground in addition to vibration of onboard instruments, structural distortion by heat, and degradation of materials by radiation even in outer space.
