The Phoenix mission investigated patterned ground and weather in the northern arctic region of Mars for 5 months starting 25 May 2008 (solar longitude between 76.5 degrees and 148 degrees ). A shallow ice table was uncovered by the robotic arm in the center and edge of a nearby polygon at depths of 5 to 18 centimeters. In late summer, snowfall and frost(More)

Introduction: The microscope station of the Phoenix Lander is able to image the dust and soil of Mars at unprecedented resolution, with a 4 !m resolution for the optical microsope and less than 100 nm with the atomic force microscope [1]. Soil was delivered by the robot-arm scoop of Phoenix to a series of substrates for imaging by the two microscopes. We(More)

The caudal migration of facial branchiomotor (FBM) neurons from rhombomere (r) 4 to r6 in the hindbrain is an excellent model to study neuronal migration mechanisms. Although several Wnt/Planar Cell Polarity (PCP) components are required for FBM neuron migration, only Celsr1, an atypical cadherin, regulates the direction of migration in mice. In Celsr1(More)
