  • New evidence for early life on Mars: NASA

    11/30/2009 6:10:56 PM PST · by KevinDavis · 12 replies · 346+ views
    CBC News ^ | 11/30/09
    A new NASA study of a Martian meteorite that made headlines 13 years ago strengthens the original claim that the rock contains evidence of life on ancient Mars. Researchers at the Johnson Space Center used advanced electron microscopes that weren't available in 1996 to re-examine the magnetite crystals on the meteorite. The meteorite, called ALH84001, was blasted from the surface of Mars 16 million years ago, scientists say, and is thought to have landed on Earth 13,000 years ago. An American scientist found it in Antarctica in 1984.

    Scientists from Northern Illinois University and Nasa's Lunar and Planetary Institute in Houston found dozens of valleys, shown in red, after using new software to analyse images of the surface and create the most accurate map to date. The valleys, first spotted in 1971, were caused by a network of rivers more than twice as extensive as previously mapped, pictured right. The new map shows water channels in a belt between the equator and mid-southern latitudes. Experts say this is consistent with heavy rain, and the presence of an ocean covering most of Mars's northern half. "It would also explain...

    LOS ANGELES – For NASA's stuck Mars rover, the Spirit may be willing, but the wheels could prove too weak. The space agency on Thursday outlined a rescue plan to try to free the rover Spirit, which has been bogged in a sand trap on the red planet for half a year. The risky operation is expected to last several months. "If it cannot make the great escape from this sand trap, it's likely that this lonely spot straddling the edge of this crater might be where Spirit ends its adventures on Mars," said Doug McCuistion, who heads the Mars...

    ACTS & FACTS ^ | October 2009 | Danny Faulkner, Ph.D.
    Many people make a distinction between the origin of life and the evolution of life. In this view, biological evolution refers to the gradual development of the diversity of living things from a common ancestor, while the ultimate origin of life is a separate question. This is a legitimate point, but evolution is about much more than just biology. The evolutionary worldview is that all of physical existence, both living and non-living, arose through purely natural processes. With this broad definition of evolution, abiogenesis--the spontaneous appearance of life from non-living matter--is a necessity. If life did arise on earth by...
  • Russians to ride a nuclear-powered spacecraft to Mars

    MOSCOW – A nuclear-powered spaceship that can carry passengers to Mars and beyond may sound like science fiction. But Russian engineers say they have a breakthrough design for such a craft, which could leapfrog them way ahead in the international race to build a manned spacecraft that can cover vast interplanetary distances. They claim they’ll be ready to build one as early as 2012. In a meeting with top Russian space scientists Wednesday, President Dmitry Medvedev gave the nuke-powered space craft a green light and pledged to come up with the cash to cover its $600-million price tag. “It’s a...

    Neil Armstrong's first small step for man was widely believed to be the start of a long and glorious road to the stars. Forty years after the first Moon landing, the dream has faded. Astronauts have been stuck in low-Earth orbit, boldly going nowhere. American attempts to kick-start a new phase of lunar exploration have stalled amid the realisation that Nasa's budget is too small for the job. And last week, a committee chaired by the aerospace engineer Norman Augustine concluded that "no plan compatible with the … 2010 budget profile permits human exploration to continue in any meaningful way".

    A series of huge cracks etched across crater basins on Mars were caused by lakes that have since evaporated, a new study concludes. The cracks were initially thought to have been merely a byproduct of thermal contractions in the Martian permafrost. But a closer examination revealed the cracks were too big for that explanation. Cracks caused by thermal contraction have a maximum diameter of roughly 213 feet (65 meters), according to analytical models.

    ... The most challenging impediment to human travel to Mars does not seem to involve the complicated launching, propulsion, guidance or landing technologies but something far more mundane: the radiation emanating from the Sun’s cosmic rays. The shielding necessary to ensure the astronauts do not get a lethal dose of solar radiation on a round trip to Mars may very well make the spacecraft so heavy that the amount of fuel needed becomes prohibitive. There is, however, a way to surmount this problem while reducing the cost and technical requirements, but it demands that we ask this vexing question: Why...

    An image of the Victoria Crater in the Meridiani Planum region of Mars was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. The image was captured at more of a sideways angle than earlier images of this crater. This view is similar to what would be observed by looking out the window of an airplane flying over Mars. The camera pointing was 22 degrees east of straight down (east is at the top of the image).

Now a University of Colorado at Boulder research team claims "the first definitive evidence of shorelines on Mars" in a statement released today.

    Some pesky scientists have just pointed out an appalling design error in NASA’s latest attempts to find life on Mars. This is beginning to look like a conspiracy. Does someone not want us to find life on Mars? NASA has tried looking for signs of life on Mars precisely once, in the 1976 Viking mission. The result was positive. The reason nobody says there is life on Mars is that another experiment, part of the same mission, couldn’t find any carbon-based “organic” chemicals in Martian soil. This, NASA decided, overruled the other result: with no carbon present, there could be...

    "We often tell ourselves that we are very fortunate living on this planet because we have this strong magnetic shield that protects us from all sorts of things that the cosmos throws at us -- cosmic rays, solar flares and the pesky solar wind," said Christopher Russell, a professor of geophysics and space physics at the University of California, Los Angeles. "It certainly does help in some of those areas but ... in the case of the atmosphere, this may not be true," he said. Russel and others came to this realization while meeting at a comparative planetology conference last...

    As first reflected upon through Twitter, Wednesday, June 10, 2009: "Our hearts and prayers go out to the shooting victims at the National Holocaust Museum. The museum itself remembers and honors the lives lost in one of the world's most horrific genocides. To have an act of intolerance further spread hatred at this place of reflection, further adds to the grief. My heart goes out to all those impacted, especially the brave guards who acted so selflessly to prevent further injury. May God Bless the Jewish community." Governor Sarah Palin

    The president of a national women's public policy group on Thursday blasted David Letterman's "offensive" jokes about Sarah Palin and her daughter and called on the CBS late-night host to formally apologize. "There's a saying that out of the heart, the mouth speaks, and Letterman's statement reveals a pretty ugly reflection of who Letterman may be," Wendy Wright, president of Concerned Women for America, told FOXNews.com. "When he said those things, they were thought through. He probably kicked them around with his writers who thought it was appropriate to say these reprehensible things." Letterman has been under fire since he...

  • NASA Scientists Find Evidence For Liquid Water On A Frozen Early Mars

    ScienceDaily (June 2, 2009) — NASA scientists modeled freezing conditions on Mars to test whether liquid water could have been present to form the surface features of the Martian landscape. Researchers report that fluids loaded with dissolved minerals containing elements such as silicon, iron, magnesium, potassium and aluminum, can remain in a liquid state at temperatures well below freezing. The results of this research appear in the May 21 issue of Nature magazine entitled "Stability Against Freezing of Aqueous Solutions on Early Mars."
  • Sun Stealing Earth's Atmosphere

    Unlike, say, Mars's or Venus's, Earth's atmosphere was thought to be untouchable inside our protective magnetic field. But a new study says the sun is slowly "stealing" our atmosphere -- and at a greater rate than on Mars or Venus. Mars, for example, probably started out with a thick atmosphere similar to Earth's. But without a magnetic field to protect the Martian atmosphere, the solar wind -- actually a stream of charged particles from the sun -- has been eroding it away. Venus also lacks a magnetosphere and is being stripped of its atmospheric covering. Currently its rate of loss...
