Nina Jarvis (Samantha Ferris) is in "Impact," a four-hour sci-fi mini-series about humanity's efforts to survive after the moon is hit by a meteor and enters into a collision course with Earth. She plays the head of Homeland Security. It premiered Sunday 6/21/09 on ABC. The next episode is Sunday, 6/28/09, 9 p.m.

Finally got around to watching the first half of "Impact". I would call it a dog, but there is no reason to insult the canine population of the planet. I'm giving the second half a pass.
