Part of that photograph shows the central uplift structure in the crater. Rocks that form this peak were several kilometers beneath the surface until an impact formed the 37 mile-diameter (60 kilometer) crater just north of Mars' equator. The HiRISE image shows that boulders as large as 50 feet across (15 meters) have eroded from the massive uplifted rock and rolled downslope.
The HiRISE image also confirms earlier evidence that this part of Mojave crater appears untouched by liquid water. Previous photographs taken by the HiRISE camera, and even earlier by the Mars Orbital Camera that flew on NASA'S Mars Global Surveyor, show that Mojave crater rim walls feature striking drainage channels and alluvial fans that likely were formed by surface water runoff. How runoff formed these channels and alluvial fans is one of the questions that HiRISE team members and their collaborators are looking into.
The High Resolution Science Imaging Experiment (HiRISE) team, led by University of Arizona Professor Alfred S. McEwen, is based at UA's Lunar and Planetary Laboratory in Tucson. HiRISE began the science phase of the mission in November, 2006, and posts new images and captions on the Internet at http://hirise.lpl.arizona.edu every Wednesday.
More information about the Mars Reconnaissance Orbiter mission is available at http://www.nasa.gov/mro. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, is the prime contractor for the project and built the spacecraft. The HiRISE camera was built by Ball Aerospace and Technologies Corp., Boulder, Colo.

Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
