PHOE-SOL104-PIA11153.jpgVastitas' Dust Devil - Sol 10492 visiteThe vertical post near the left edge of this image is the "Mast" of the Meteorological Station on Phoenix.
The DD visible at the horizon just to the right of the mast is estimated to be 600 to 700 meters (about 2000 to 2300 feet) from Phoenix, and 4 to 5 meters (10 to 13 feet) in diameter.
It is much smaller than DDs that have been observed by NASA's Mars Exploration Rover Spirit much closer to the Equator and it is closer in size to Dust Devils seen from orbit in the Phoenix Landing Region, though still smaller than those.
The image has been enhanced to make the Dust Devil easier to see. MareKromium

PHOE-SOL099-PIA11073.jpgPhoenix Conductivity Probe after Extraction - Sol 99 (natural colors; credits: NASA)89 visiteCaption NASA:"NASA's Phoenix Mars Lander inserted the 4 needles of its Thermal and Conductivity Probe into Martian soil during the 98th Sol of the mission and left it in place until Sol 99 (Sept. 4, 2008).
The Surface Stereo Imager on Phoenix took this image on the morning of Sol 99 after the probe was lifted away from the soil. This imaging served as a check of whether soil had stuck to the needles.
The Thermal and Conductivity Probe measures how fast heat and electricity move from one needle to an adjacent one through the soil or air between the needles. Conductivity readings can be indicators about water vapor, water ice and liquid water.
The probe is part of Phoenix's Microscopy, Electrochemistry and Conductivity suite of instruments".MareKromium

00-PhoenixLiftoff.jpgThe beginning...86 visiteCaption NASA:"Can Mars sustain life? To help answer this question, last week NASA launched the Phoenix Mission to Mars. In May 2008, Phoenix is expected to land in an unexplored North Polar Region of Mars that is rich in water-ice. Although Phoenix cannot move, it can deploy its cameras, robotic arm, and a small chemistry laboratory to inspect, dig, and chemically analyze its landing area. One hope is that Phoenix will be able to discern telling clues to the history of ice and water on Mars. Phoenix is also poised to explore the boundary between ice and soil in hopes of finding clues of a habitable zone there that could support microbial life.
Phoenix has a planned lifetime of 3 months on the Martian surface".MareKromium
