The first test flight of a solar sail has been delayed by damage caused
during pre-flight testing. The sail鈥攚hich uses pressure from the solar
wind to propel a spacecraft鈥攚as due to be launched next week from a
Russian nuclear submarine in the Barents Sea for a sub-orbital flight. It was
damaged when the flight test routine was accidentally triggered during ground
tests near Murmansk. 鈥淭he extent of damage is not known at this time,鈥� says
Louis Friedman of the Planetary Society, the private body which is funding the
test.
