    Freedom Outpost ^ | March 29, 2014 | Michael Snyder
    Can you imagine the devastation that would be caused if a massive wall of water several hundred feet high slammed into Florida at more than 100 miles an hour? To many people such a scenario is impossible, but that is what people living along the Indian Ocean thought before the 2004 tsunami and that is what people living in Japan thought before the 2011 tsunami. Throughout history, giant tsunamis have been relatively rare events, but they do happen. Scientists tell us that a mega-tsunami can race across the open ocean at up to 500 miles an hour, and when they...
  • NASA's comet hunting 'Deep Impact' comes to an end

    09/22/2013 9:49:49 PM PDT · by jenniferadam · 6 replies
    A Boeing Delta II rocket carries NASA's Deep Impact spacecraft as it lifts off in Cape Canaveral, Florida, on January 13, 2005. In a first-of-its-kind mission, the spacecraft was sent to gather information about the comet Temple 1. NASA declared the mission complete on Friday, September 20. The most-traveled comet-hunter mission in history has ended, NASA announced this Friday rather with reluctance as it shut the book on the Deep Impact spacecraft. see more @ Nasa News

    After almost nine years in space that included an unprecedented July 4th impact and subsequent flyby of a comet, an additional comet flyby, and the return of approximately 500,000 images of celestial objects, NASA's Deep Impact mission has ended. The project team at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, has reluctantly pronounced the mission at an end after being unable to communicate with the spacecraft for over a month. The last communication with the probe was August 8th. Deep Impact was history's most traveled comet research mission, going about 4.7 billion miles (7.58 billion kilometers). "Deep Impact has...

    NASA's Stardust spacecraft returned new images of a comet showing a scar resulting from the 2005 Deep Impact mission. The images also showed the comet has a fragile and weak nucleus. The spacecraft made its closest approach to comet Tempel 1 on Monday, Feb. 14, at 8:40 p.m. PST (11:40 p.m. EST) at a distance of approximately 178 kilometers (111 miles). Stardust took 72 high-resolution images of the comet. It also accumulated 468 kilobytes of data about the dust in its coma, the cloud that is a comet's atmosphere. The craft is on its second mission of exploration called Stardust-NExT,...

    NASA sends spacecraft on mission to comet Hartley 2 NASA/JPL NEWS RELEASE Posted: December 15, 2007 NASA has approved the retargeting of the Epoxi mission for a flyby of comet Hartley 2 on Oct. 11, 2010. Hartley 2 was chosen as Epoxi's destination after the initial target, comet Boethin, could not be found. Scientists theorize comet Boethin may have broken up into pieces too small for detection. The Epoxi mission melds two compelling science investigations -- the Extrasolar Planet Observation and Characterization and the Deep Impact Extended Investigation. Both investigations will be performed using the Deep Impact spacecraft. In addition...

    A pale green interloper among the stars of Cassiopeia, Comet Hartley 2 glows like an escapee from Krypton at the center of this exposure taken on the night of Sept. 28, 2010, by NASA astronomer Bill Cooke. Still too faint to be seen with the unaided eye, the comet was 18 million miles away from Earth at the time. Cooke took this image using a telescope located near Mayhill, N.M., which he controlled via the Internet from his home computer.

    A greenish comet named 103P/Hartley 2 flew within 11 million miles of the Earth on Wednesday, one of the closest approaches by a comet in centuries. But hardly anyone is likely to see it until a Maryland-led NASA mission sends a spacecraft past on Nov. 4. While the comet has been visible in the northern sky for weeks, it has been a difficult target for backyard stargazers, especially in light-polluted suburban skies. "This is probably one of the best comets of the year," said Armen Caroglanian, a member of an employees' astronomy club at the NASA Goddard Space Flight Center....

    BIG GREEN COMET: The icy nucleus of comet 103P/Hartley 2 measures no more than a couple of kilometers across. That tiny nugget, however, is surrounded by an vast atmosphere of gas more than 150,000 km in diameter--about the same size as the planet Jupiter! And it's coming our way. Amateur astronomer Nick Howes sends this picture of the approaching comet from Cherhill, WIltshire UK: "I photographed the comet on Oct. 1st using a 4-inch refractor," says Howes. "Four hours of exposure time revealed not only the comet's vast green atmosphere but also an emerging tail." Howes describes the processing of...

    In late June of 1908, a fireball exploded above the remote Russian forests of Tunguska, Siberia, flattening more than 800 square miles of trees. Researchers think a meteor was responsible for the devastation, but neither its fragments nor any impact craters have been discovered. Astronomers have been left to guess whether the object was an asteroid or a comet, and figuring out what it was would allow better modeling of potential future calamities. Italian researchers now think they've found a smoking gun: The 164-foot-deep Lake Cheko, located just 5 miles northwest of the epicenter of destruction. "When we looked at...

    Although comets form at the frigid edges of the solar system, they appear somehow to contain minerals that form only in the presence of liquid water, and at much warmer temperatures, scientists are reporting today. On July 4, as planned, part of the Deep Impact spacecraft - essentially an 820-pound, washing machine-size bullet - slammed into the comet Tempel 1 at 23,000 miles an hour. The collision tossed up thousands of tons of ice and dust from the comet that were observed by telescopes on Earth as well as small flotilla of spacecraft. One of the observers was the Spitzer...

    BALTIMORE - The Hubble Space Telescope has given astronomers a sneak preview of what they might see July 4 when a NASA probe strikes a comet, creating a cosmic display that may be visible with the naked eye in part of the Western Hemisphere. One of a series of photos taken by the orbiting observatory while preparing for the Independence Day encounter shows a 1,400-mile plume of dust spewing from the comet toward the sun. Johns Hopkins University astronomy professor Paul Feldman said light from the sun most likely heated a pocket of volatile gas trapped beneath the surface, causing...

    LOS ANGELES (AP) - Not all dazzling fireworks displays will be on Earth this Independence Day. NASA hopes to shoot off its own celestial sparks in an audacious mission that will blast a stadium-sized hole in a comet half the size of Manhattan. It would give astronomers their first peek at the inside of one of these heavenly bodies. If all goes as planned, the Deep Impact spacecraft will release a wine barrel-sized probe on a suicide journey, hurtling toward the comet Tempel 1 - about 80 million miles away from Earth at the time of impact. "It's a bullet...

    I don't get it. Why are Xinhua and AlJazeera listed as the first news sources that comment on NASA's Deep Impact mission? Followed closely by The Standard (Hong Kong), Globe and Mail (Canada), Australian (Australia), AME Info (United Arab Emirates). Google News confounds me.

    Comet-hitting probe tweaks its course to target NASA NEWS RELEASE Posted: May 15, 2005 Fifty-nine days before going head-to-head with comet Tempel 1, NASA's Deep Impact spacecraft successfully executed the second trajectory correction maneuver of the mission. The burn further refined the spacecraft's trajectory, or flight path, and also moved forward the expected time of the Independence Day comet encounter so impact would be visible by ground- and space-based observatories. The 95-second burn - the longest remaining firing of the spacecraft's motors prior to comet encounter -- was executed on May 4. It changed Deep Impact's speed by 18.2 kilometers...
  • Astrologer to sue NASA

    Moscow - A Russian court ruled that an astrologer could proceed with a lawsuit against the United States National Aeronautics and Space Administration for plans to bombard a comet whose destruction would "disrupt the natural balance of the universe", said Itar-Tass on Friday. Star-reader Marina Bai's case was thrown out of a lower court because Russia had no jurisdiction over Nasa. But, the ruling was overturned when her lawyer, Alexandra Molokhova, was able to show that the agency's office in the US embassy in Moscow did fall under Russian jurisdiction. Bai seeks a ruling that would restrict Nasa in its...

    Russian Astrologist Sues NASA NASA has been taken to court in Russia over its plans to crack open a comet. Marina Bai, a Russian astrologist, filed a lawsuit last month with the Presnensky district court in Moscow, demanding that the U.S. space agency call off its $311 million Deep Impact mission. As reported in MosNews.com, Bai is also asking for 8.7 billion rubles ($311 million) in compensation for moral damages. “The actions of NASA infringe upon my system of spiritual and life values, in particular on the values of every element of creation, upon the unacceptability of barbarically interfering with...

    PASADENA, Calif. (AP) - NASA's Deep Impact spacecraft is on course for a July 4 encounter with comet Tempel 1 but mission officials are trying to determine why a telescope that will function as its main science instrument has not reached proper focus, the space agency said Friday. Officials nonetheless expressed confidence that the mission will not be affected by the problem. Deep Impact carries an "impactor" that will be released to collide with the comet, possibly creating a stadium-size gouge while the spacecraft's instruments collect data on the material that is hurled off. The craft was launched on Jan....
  • 'Your name here' proposed for comet

    If you've ever wanted your name on a comet, now's your chance. Pasadena's Jet Propulsion Laboratory and NASA plan to send a satellite to crash into a comet in 2005 and aboard the craft will be a CD with the names of perhaps thousands of Earthlings. The names will be carried on board NASA's Deep Impact spacecraft, the first deep-space mission designed to collide with a comet. Mission scientists are confident an impact on the nucleus of a comet called Tempel 1 will answer basic questions about the nature and composition of these celestial wanderers. "This is an opportunity...
