An interplanetary weather satellite bound for Venus and adevice to test new propulsion techniques were trucked across Japan's islandspace center Sunday to meet the H-2A rocket that will launch the payloads intospace next week.
Cocooned inside the launcher's nose shroud, the payloads wereloaded onto a trailer and driven less than a mile from a checkout facility tothe Vehicle Assembly Building at the Tanegashima Space Center's Yoshinobulaunch complex.
After engineers complete testing of the rocket, the 17-storyvehicle will roll on rail tracks about 1,500 feet to the launch pad nextMonday. Once the rocket arrives at the launch pad, workers will load liquidhydrogen and liquid oxygen propellant into the H-2A's first and second stages.
Flying for the 17th time, the H-2A rocket on this missioncarries a pair of powerful solid rocket boosters and no smaller strap-onmotors. This configuration is called the "202" version.
The launch will occur at 6:44 a.m. local time atTanegashima, a narrow strip of land off the coast of Japan's Kyushu Island, thesouthernmost of the country's four largest land masses.
Akatsuki should reach Venus by December if it gets off theground during a planetary window stretching between May and June. Akatsuki willcarry six instruments to study the Venusianatmosphere from its outer boundary with space to the planet's hellishsurface.
The probe will enter an equatorial orbit around Venusstretching from just above the planet's blanketing atmosphere to an altitude ofnearly 50,000 miles. It will be ideally placed to observe the whipping windsthat drive massive storm systems in the Venusian atmosphere.
