Summary of Assigned Article
(Pick out the key points of the article, Less than 200 words)
The chemical NASA's Phoenix Mars Lander found in a sample of Martian dirt. The discovery of an odd type salt that scientists think could have made an important impact on Mar's water cycle and it's ability to support life. The salt is called perchlorates. Perchlorate can melt ice even at the frigid temperatures seen at the bottom of the ice caps. Perchlorate salts may play a key role in regulating the flow of water between atmosphere and surface on Mars because "these are compounds that suck up water," Arvidson explained.
