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.

Shape matters when light meets atom

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
