ISAS Deloyed Solar Sail Film in Space

ISAS succeeded in deploying a big thin film for solar sail in space for the
first time in the world.

ISAS launched a small rocket S-310-34 from Uchinoura Space Center in Kagoshima,
Japan, at 15:15 [0615 UTC], August 9, 2004 (Japan Standard Time). The launch was
the culmination of a historic new technology, the world-first successful
full-fledged deployment of big films for solar sail.

A solar sail is a spacecraft without a rocket engine. It is pushed along
directly by light particles from the Sun, reflecting off its giant sails.
Because it carries no fuel and keeps accelerating over almost unlimited
distances, it is the only technology now in existence that can one day take us
to the stars.

Although both scientists and science-fiction authors have long foreseen it, no
solar sail has ever been launched until now. It is because superlight material
for thin film which could bear extremely critical environment in space. Now due
to the development of material and production technology, we can utilize
promising film materials for solar sail, and the experimental deployment trials
toward realization of solar sail have been initiated in some countries.

The S-310 rocket which was launched from Uchinoura Space Center at 15:15 of
August 9, 2004, carried two kinds of deploying schemes of films with 7.5
micrometers thickness. A clover type deployment was started at 100 seconds after
liftoff at 122 km altitude, and a fan type deployment was started at 169 km
altitude at 230 seconds after liftoff, following the jettison of clover type
system. Both experiments of two types deployment were successful, and the rocket
splashed on the sea at about 400 seconds after liftoff.

Should that be first time "out of this world?"
