I enjoyed Pioneer 12's visit to Venus.
Yours truly, standing in for a controller in Fig 2-12. :-)

We have posted a preview of the Ikaros solar sail that is launching as a secondary payload aboard the H-2A rocket.
1555 GMT (11:55 a.m. EDT)
The rocket is now fully fueled for launch. Launch controllers just finished loading liquid hydrogen and liquid oxygen into both stages of the H-2A rocket.
The first stage LE-7A engine consumes hydrogen during its six-and-a-half minute firing. The second stage's LE-5B powerplant will ignite twice to place the Akatsuki orbiter on track for Venus.
The H-2A's two solid rocket boosters burn solid propellant, which has already been packed inside the motors.

AKATSUKI/IKAROS Launch rescheduled to 6:58 a.m. on the 21st (Fri) The launch of the Venus Climate Orbiter "AKATSUKI" and the Small Solar Power Demonstrator "IKAROS" by the H-IIA Launch Vehicle No. 17 was rescheduled at 6:58:22 a.m. on May 21 (Fri. Japan Standard Time, JST) after carefully studying the weather conditions.
Accordingly, the live launch report will begin at 6:30 a.m. on May 21(Fri., JST.) The report will be broadcast not only through the Internet, but also at JAXA i, Sagamihara Campus and other public viewing locations including some universities. You can also watch it through some CATV and cell phone providers.

AKATSUKI (PLANET-C) is the next planetary exploration project for the Martian orbiter NOZOMI. This project’s main purpose is to elucidate the mysteries of the Venusian atmosphere. Though often referred to as Earth’s sister planet in terms of size and mass, Venus is actually very different. It is veiled in carbon dioxide, with a high temperature and thick sulfuric-acid clouds. Clarification of the causes for this environment will provide us with clues to the understanding of the birth of Earth and of its climate changes. Therefore, Venus is a very important subject for exploration.
AKATSUKI will usher in a new era of Venusian exploration. The probe vehicle is scheduled to be launched in FY 2010 and is expected to reach Venus orbit.

H-2A rolls out to launch pad for second time
The 174-foot-tall H-2A rocket moved from the Vehicle Assembly Building to Launch Pad No. 1 at Japan's island spaceport around midday Thursday, local time. It was the second time the rocket has rolled to the pad. The first launch attempt Monday was scrubbed by thick clouds.

Leading edge, efficient and economical technology Japanese main large-scale launch vehicle, H-IIA
H-IIA, Japan’s primary large-scale launch vehicle, is designed to meet diverse launch demands, at lower cost and with a high degree of reliability, by making the best use of the H-II launch-vehicle technology. The simplified design and improved efficiency of the manufacturing and launch processes of H-IIA have achieved one of the highest performance to cost ratio of launch system in the world, reducing the cost of launches by a half or more.
H-IIA launch service operations have been transferred to Mitsubishi Heavy Industries, LTD. ahead of the launch of H-IIA Flight 13. JAXA is in charge of launch safety management (including ground safety confirmation, flight safety assurance, and overall countdown control and supervision.)

Space yacht accelerated by radiation of the Sun
A Solar Sail gathers sunlight as propulsion by means of a large membrane while a Solar "Power" Sail gets electricity from thin film solar cells on the membrane in addition to acceleration by solar radiation. What's more, if the ion-propulsion engines with high specific impulse are driven by such solar cells, it can become a "hybrid" engine that is combined with photon acceleration to realize fuel-effective and flexible missions.
JAXA is studying two missions to evaluate the performance of the solar power sails. The project name for the first mission is IKAROS (Interplanetary Kite-craft Accelerated by Radiation Of the Sun). This craft will be launched with the Venus Climate Orbiter "AKATSUKI", using an H-IIA launch vehicle. This will be the world's first solar powered sail craft employing both photon propulsion and thin film solar power generation during its interplanetary cruise.
