    This oblique view from NASA's Dawn spacecraft shows Rao Crater (7 miles, 12 kilometers) at center left.
    Dawn took this image on May 30, 2016, from its low-altitude mapping orbit, at a distance of about 385 km
    above the surface. The image resolution is 35 meters per pixel.

    SpaceX has shipped its Mars engine to Texas for tests | Ars Technica
    http://arstechnica.com/science/2016/08/spacex-has-shipped-its-mars-engine-to-texas-for-tests/
    SpaceX appears to have taken a significant step forward with the development of a key component of its Mars mission architecture.
    According to multiple reports, during the Small Satellite Conference Tuesday in Logan, Utah, SpaceX President Gwynne Shotwell said
    the company has shipped a Raptor engine to its test site in MacGregor, Texas. A spokesman confirmed to Ars that the engine has
    indeed been moved to Texas for developmental tests.

    Asteroid Redirect Mission at Critical Juncture
    http://www.spacepolicyonline.com/news/asteroid-redirect-mission-at-critical-juncture
    Three weeks after NASA completed a key milestone review of the Asteroid Redirect Mission (ARM),
    the agency still has not officially announced the results. A NASA official indicated at a NASA
    Advisory Council (NAC) meeting that the review revealed cost growth, forcing a reexamination of
    its objectives versus the cost. An Obama Administration initiative, it is at a critical juncture
    as the House Appropriations Committee denied funding earlier this year and President Obama’s term
    in office comes to an end in just 5 months.

    Commercial Space to Smash the Astronomy 'Funding Wall'?
    http://www.seeker.com/could-commercial-space-solve-the-astronomy-funding-wall-1964677465.html
    There's been much coverage of the more than $9 billion James Webb Space Telescope that will launch in 2018, to probe planetary atmospheres and to look
    back at the universe's beginnings. What will come next? Looking a bit ahead, the astronomy organization AURA suggests a "High Definition Space Telescope"
    to launch in 2035, an observatory double Webb's size. But how this would be paid for comes under scrutiny in a new report.

    Harvard astrophysicist Martin Elvis' new paper in Space Policy to try to solve what he calls the astronomy "funding wall." Our hunger for greater telescopes
    in X-ray emissions alone, he argues, has made the cost of this mission type increase 20 times in the past generation. (Yes, that's after adjusting for
    inflation.) Moreover, space missions often go over their budget before launch.

    1967 solar storm nearly took US to brink of nuclear war
    https://news.agu.org/press-release/1967-solar-storm-nearly-took-us-to-brink-of-war/
    A solar storm that jammed radar and radio communications at the height of the Cold War could have led to a disastrous
    military conflict if not for the U.S. Air Force’s budding efforts to monitor the sun’s activity, a new study finds.

    Large aeolian ripples on Mars | Planetary Geomorphology Image of the Month
    https://planetarygeomorphology.wordpress.com/2016/07/30/dune-ripples-on-earth-and-mars/
    Ripples cover the surfaces of sand dunes on Earth and Mars. On Earth, ripples formed in typical aeolian sand (e.g., 0.1 and 0.3 mm)
    range in wavelength between 10 and 15 cm and display a highly straight, two-dimensional crestline geometry. Ripples are thought to
    develop through a process dominated by the ballistic impacts of saltating sand grains in which wavelength selection occurs through
    the interplay of grain size, wind speed, the saltation trajectories of the sand grains, and ripple topography.

    Rocks in Chile Help Scientists Hunt for Life on Mars - Eos
    https://eos.org/research-spotlights/rocks-in-chile-help-scientists-hunt-for-life-on-mars
    Robots like Viking, Phoenix, and Curiosity have found indirect evidence of oxalate minerals on Mars. New techniques
    tested in the Chile’s Atacama Desert could help future Mars rovers analyze these minerals for possible by-products of life.

    Organic oxalates tie up carbon, creating carbon sinks that are extremely resistant to most physical and chemical weathering.
    On Earth, oxalates are primarily broken down by biological weathering; fungus and bacteria consume oxalate, recycling carbon
    back into the environment. But Mars’s carbon cycle is not as well understood. Developing better techniques to identify trace
    concentrations of oxalates may provide insights into the processes at play on the Red Planet.

    NEBULA: No ahój! To je prima tě tu vidět. :)

    No jasně - špička Perseid se blíží, takže Murphyho zákony zase pracují s přesností švýcarek.
    Dnes se zatáhlo, navíc předpovědi nic moc, a to ještě o víkendu vypadaly tak dobře!
    Když jsem sem dnes házel ten návod na pozorování, hodně škodolibě jsem se pochechtával...
    Už z toho letos začíná být tradice - při rojích je zkrátka hnusně. Už si to koleduje o pranostiku.
    Třeba: "Na svatého Perseida - na obloze zmar a bída". (na "Persea" jsem nenašel rým...:D)

    No dobrý večer miláčkové, byla jsem nějakou dobu mimo signál a připojení, takže to chvíli potrvá než se zorientuju, nicméně nesu sem zprávu, že Perseidy lítaj :) včera teda totálka jasno, nádhera krása, čekala jsem až proletí a proletěl jeden nádhernej snad přes celý nebe :) asi tak přesně o půlnoci, a jasnost vzestupná, pak sestupná a zas vzestupná, zajímavé, uchvacující, no snad se nám to dnes vyprší a zítra bude zas viditelnost... :)

    Dark Energy Spectroscopic Instrument to Measure Light from 35M Cosmic Objects in Effort to Understand Expansion of the Universe
    DOE Approves Construction of 3-D Galaxy-mapping Project ‘DESI’ | SLAC National Accelerator Laboratory
    https://www6.slac.stanford.edu/...-09-doe-approves-construction-3-d-galaxy-mapping-project-desi.aspx
    A 3-D sky-mapping project that will measure the light of 35 million cosmic objects has received formal approval from the Department of Energy
    to move forward with construction. Installation of the project, called Dark Energy Spectroscopic Instrument (DESI), is set to begin next year
    at the Mayall 4-meter telescope at Kitt Peak National Observatory near Tucson, Arizona, with observations starting up in January 2019.

    Tabby's star, alien megastructures, and Dyson spheres: This mysterious planet refuses to reveal its secrets — Quartz
    http://qz.com/...alien-hunters-are-fixated-on-a-mysterious-star-which-refuses-to-reveal-its-secrets/
    A flurry of studies published over the past year show that the more data scientists collect, the stranger the star’s tale becomes.
    Every attempt to rule out the alien-megastructure hypothesis is met with more data that stops it from being discarded.
