A Russian astrologist who says NASA has altered her horoscope by crashing a spacecraft into a comet is suing the U.S. space agency for damages of $300 million, local media reported Monday.

　　NASA deliberately crashed its probe, named Deep Impact, into the Tempel 1 comet to unleash a spray of material formed billions of years ago which scientists hope will shed new light on the composition of the solar system.

　　"It is obvious that elements of the comet's orbit, and correspondingly the ephemeris, will change after the explosion, which interferes with my astrology work and distorts my horoscope," Izvestia daily quoted astrologist Marina Bai as saying in legal documents submitted before Monday's collision.

　　A spokeswoman for a Moscow district court said initial preparations for the case were underway but could not say when the hearing would begin. NASA representatives in Moscow were unavailable for comment.
