NASA's moon-colliding probe LCROSS lost more than half its propellant late last week after a glitch caused it to repeatedly fire its thrusters to try to orient itself. But the spacecraft is still on track to complete its mission to slam into the moon's south pole in October.
CLASSIFICATION: B2; probable human carcinogen. BASIS FOR CLASSIFICATION: Tumors have been induced in mice, rats and hamsters following oral, inhalation or intraperitoneal administration of hydrazine and hydrazine sulfate. Hydrazine is mutagenic in numerous assays. HUMAN CARCINOGENICITY DATA: Inadequate. ANIMAL CARCINOGENICITY DATA: Sufficient.

What really confuses me is why LCROSS was out of contact with earth for a full 20 hours! Surely the amount these projects cost you would not let it out of contact for any great length of time

(CNN) -- NASA lost a $125 million Mars orbiter because one engineering team used metric units while another used English units for a key spacecraft operation, according to a review finding released Thursday.
For that reason, information failed to transfer between the Mars Climate Orbiter spacecraft team at Lockheed Martin in Colorado and the mission navigation team in California. Lockheed Martin built the spacecraft.
"People sometimes make errors," said Edward Weiler, NASA's Associate Administrator for Space Science in a written statement.
