This image is the result of the Mars Phoenix mission team instructing the robotic arm camera to look under the vehicle. What you are looking at is the surface of Mars, and it shows that the Martian soil has been displaced by the landing thrusters on Phoenix to expose what is most probably ice. The simple action of Phoenix landing on Mars has potentially exposed polar ice directly under the vehicle, ice that was covered by a very loose and thin layer of soil.

There is a rumor that when the mission leaders saw this image the first words uttered were “Holy cow!”

The Phoenix robotic explorer has been on Mars now for about 27 hours after an incredibly successful entry, descent and landing. It has been very busy. Incredible images are already streaming to Earth, and those of us geeked out by things of this nature are absolutely riveted. I was excited to discover how many people I know were following @MarsPhoenix on Twitter.

Many images are coming back, and most right now are of the explorer itself and the immediate vicinity as the mission managers check systems and get their bearings. The above image of one of the craft’s landing pads is one of my favorites because that image is of the pad of a man-made robotic explorer sitting on the surface of Mars millions of miles away from Earth, and it was taken in the last 24 hours. Astounding. Even more astounding is this video composite of the Martian surface, terrain and horizon taken by Phoenix today.

We are at just under four hours before Phoenix lands on the surface of Mars. I am checking periodically at the Phoenix mission control website in anticipation of this event. Martian weather is clear and the landing later today is green for go. I suspect there are a lot of very excited and anxious people at JPL right now.

The above animation is of weather on Mars around its north pole from 5/16 through 5/22. The small cigar shaped outline in the upper left quadrant is the planned landing zone.
