Phoenix lander discovery -place your bets-
What do you think the mysterious white substance is? * Salt * Ice * Other Joe Bauman, I'm particularly interested in your take on this.

Definitely ice.

"Definitely ice" is more wishful thinking on my part than it is verified data. Quoting from a recent article posted on Space.com: ++++++++++++ Scientists have found no indications so far of water in the first soil sample delivered to NASA's Mars Phoenix Lander, they announced on Monday. After finally successfully delivering the sample to the Thermal and Evolved-Gas Analyzer (TEGA) on June 11, mission scientists carried out their first two analyses of the sample over the weekend. During the first, the sample was heated to 95 degrees Fahrenheit (35 degrees Celsius), in the hopes of melting out any water ice in the sample. The sample was further heated up to 350 F (175 C) during the second analysis. "We saw no water coming off the soil whatsoever," said TEGA team leader William Boynton of the University of Arizona. ++++++++++++ Seth -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Chuck Hards Sent: Wednesday, June 18, 2008 11:20 AM To: Utah Astronomy Subject: Re: [Utah-astronomy] Phoenix lander discovery -place your bets- Has sublimation been observed yet?

Any mission scientists talking about CO2 ice yet? On Wed, Jun 18, 2008 at 11:41 AM, Seth Jarvis <SJarvis@slco.org> wrote:

It's summer on Mars isn't it? Too bad they didn't land on an ice cap.

They might still be in spring. I think they are two and a half weeks behind us. ;) Quoting erikhansen@TheBlueZone.net:

I believe great pains were taken to select a topographically flat landing area. Apparently coming down on too steep an incline, half-meter boulder, or falling into a crevasse is bad for the lander. On Wed, Jun 18, 2008 at 2:02 PM, <erikhansen@thebluezone.net> wrote:

No Guts no Glory.

Yes, lots of scientists expect to see CO2 ice, but from what I read, it'll be at least another week before more extensive tests will be conducted.

I read that they were going to watch closely for signs of sublimation on one of the exposed white patches. That should happen quickly regardless of whether it's H2O or CO2 ice, and won't require any on-board testing. On Wed, Jun 18, 2008 at 2:24 PM, Seth Jarvis <SJarvis@slco.org> wrote:
