The Future of Mars

While the Viking experiments were redone in the hyper-arid desert of Chile, one of Peter’s grad students, Doug Archer, investigated a mysterious gas release that the TEGA team saw at 300 degrees Celsius. Peter thinks it represents the moment perchlorate destroys the evidence of organics. Still more clues that Mars might indeed be covered with organic and possibly biologic material. We just can’t detect it quite as easily as we originally thought.

“He thinks he can show that there’s 1-10 parts per million of organic material in the soil. Now we’ve got liquid water and organics,” Peter says, pretending to smash his fist on the table as an exclamatory gesture. And it just gets better. Selby Cull, a student from Ray Arvidson’s group, is looking into evidence that there was perchlorate all over the landing site. And maybe that will lead to showing that Perchlorate is all over Mars. She thinks she sees evidence in the some of the SSI photography.
