A brief housekeeping note: if you check this site using an RSS feed, you may have missed some of my posts from yesterday, as it looks like the RSS feed updates didn't happen quite right yesterday. Try coming to the blog homepage and going through the archive to see them all.

This is a really cool image, put together by Doug Ellison, giving some context for the photos that the lander took of itself yesterday.

Phoenix "Sol 0" images in context

The photos were taken to document the deployments of the solar panels, the bio-barrier around the robotic arm, the meteorological mast, and other stuff; if things hadn't gone well last night, the photos would not have matched the base image. But the match is perfect! The base image was taken from the Texas A & M website that has much more information about the Phoenix camera system.

I'm getting a slow start to the morning, but will be up at JPL for the press briefing currently scheduled for 11 am my time (18:00 UTC). I will probably show up in the Ustream channel off and on this morning as well. Stay tuned!

Sol 0

Please tell me :
---------------
Must the day of the landers' descent on Mars
be called "sol 0" or must we call it "sol 1"?

Yours

It depends on the mission. Phoenix called their first sol Sol 0, but the rovers called it sol 1.
