Gallant’s Exploring Under the Earth was published in 1960, unconnected sensors scattered around the world could measure the force of an earth- quake. But exactly how the shock waves rattled around the planet’s interior was understood less well, as the simplified diagram below shows. Since then, the use of networked sensors and seismic modeling has vastly improved our knowledge of deep-Earth dynamics. ¶ To depict the effects of a temblor more fully, illustrator Jason Lee researched how P waves (which travel in compression like a Slinky) and S waves (which travel like undulations in a rope) move through the geologic layers. “The challenge with an earthquake is depicting the motion and how it changes over time,” Lee says. “People think of waves as linear, but a quake releases energy in all directions, making it hard to visualize.” ¶ Using simulations from a program called Seismic Waves, created by Alan Jones at Binghamton University, Lee was able to trace the complex paths traveled by that energy, including how the waves change their course (or type) when they hit areas of different density. “I first visualized the various stages of an earthquake,” he says, “and then composited some of them into a single image showing its progression through and around Earth’s core.” Exploring Under the Earth illustrated by john polgreen 1 3 9 17.11FF.vintage_science.LO;35.indd 9/28/09 11:30:17 AM PAGE 5 ACIDALIA PLANITIA ARCADIA PLANITIA OLYMPUS MONS TEMPE TERRA CHRYSE PLANITIA AMAZONIS PLANITIA LUNAE PLANUM DAEDALIA PLANUM VALLES MARINERIS ARGYRE PLANITIA AONIA TERRA 210° E 240° E 270° E 300° E 330° E MARS MAPPING L/GODDARD/USGS updated map by nasa P /J A S A THEN Telescope and graphite NOW Satellite, laser, and supercomputer MAP: N MAP: 17.11FF.vintage_science.LO;35.indd 9/28/09 11:30:24 AM PAGE 6 Exploring Mars illustrated by lowell hess PROMETHEI TERRA 30° E 60° E 90° E 120° E 150° E Maps created from Earth-based telescope images—like the one from taking measurements at 300-meter intervals over the entire surface.

Two- dimensional maps of Earth’s atmosphere like the one at right showed the distances involved in, say, putting a satellite into orbit. But a 3-D presentation of the same information can provide a more intuitive feel for the structure of the atmosphere. ¶ “The challenge in this piece,” illustrator Bryan Christie says, “is to create a richer experience—through light, shadow, refraction, and opacity—without adding clutter or los- ing legibility.” Christie’s studio not only depicted the atmospheric layers more accurately (including details like the mesosphere, missing in the earlier diagram), he also created a graphic that can stand alongside the classics of yesteryear as a work of art.

  • Dark Dunes on Mars
    CHAPTER II: PLANET MARS – THE BACKGROUND Like Earth, its neighbour planet, Mars, is a terrestrial planet with a solid surface, an atmosphere, two ice-covered pole caps, and not one but two moons (Phobos and Deimos). Some differences, such as a greater distance to the sun, a smaller diameter, a thinner atmosphere, and the longer duration of a year distinguish Mars from the Earth, not to forget the absence of life…so far. Nevertheless, there are many correlations between terrestrial and Martian geological and geomorphological processes, permitting researchers to apply knowledge from terrestrial studies more or less directly to Mars. However, a closer look reveals that the dissimilarities, though few, can make fundamental differences in process background and development. The following chapter provides a brief but necessary insight into the geological and physical background of this planet, imparting to the reader some fundamental knowledge about Mars, which is useful for understanding this work. Fig. 1 presents an impression of Mars viewed from space. Figure 1: The planet Mars: a global view (Viking 1 Orbiter mosaic [NASA]).

  • Earth-Like Aqueous Debris-Flow Activity on Mars at High Orbital Obliquity in the Last Million Years
    ARTICLE Received 25 Oct 2014 | Accepted 19 May 2015 | Published 23 Jun 2015 DOI: 10.1038/ncomms8543 OPEN Earth-like aqueous debris-flow activity on Mars at high orbital obliquity in the last million years T. de Haas1, E. Hauber2, S.J. Conway3, H. van Steijn1, A. Johnsson4 & M.G. Kleinhans1 Liquid water is currently extremely rare on Mars, but was more abundant during periods of high obliquity in the last few millions of years. This is testified by the widespread occurrence of mid-latitude gullies: small catchment-fan systems. However, there are no direct estimates of the amount and frequency of liquid water generation during these periods. Here we determine debris-flow size, frequency and associated water volumes in Istok crater, and show that debris flows occurred at Earth-like frequencies during high-obliquity periods in the last million years on Mars. Results further imply that local accumulations of snow/ice within gullies were much more voluminous than currently predicted; melting must have yielded centimetres of liquid water in catchments; and recent aqueous activity in some mid-latitude craters was much more frequent than previously anticipated. 1 Faculty of Geosciences, Universiteit Utrecht, Heidelberglaan 2, 3584 CS, Utrecht, The Netherlands. 2 Institute of Planetary Research, German Aerospace Center, Rutherfordstrasse 2, Berlin DE-12489, Germany. 3 Department of Physical Sciences, Open University, Walton Hall, Milton Keynes MK7 6AA, UK. 4 Department of Earth Sciences, University of Gothenburg, Gothenburg SE-405 30, Sweden.

This investigation, between 0 and 180 degrees.

This information will provide in- sight into the modes of dune formation and add reason- able constraints to global circulation models. Sand Transport Background: Observations of dune and ripple scale sand movements on Mars were first made by the Spirit rover [4]. Today, the High Resolution Imaging Science Experiment (HiRISE) camera provides unprecedented views of Mars, includ- ing abundant sand dunes and ripple patterns [2], with resolution as high as 25 cm/pixel [5]. However, the methods of sand transport are still debated. Wind speeds have yet to be measured in many areas and the complex structures and crest positions of dunes may be created by multiple wind directions or seasonal wind variations, which lead to ambiguities in dune interpre- tations.
