• Fin de la trève?

    Enfin de serieuses éruptions font leur apparition sur le Soleil.

     

    Seules deux taches sont répertoriées pour l'instant. 1633 au Nord et 1634 au Sud.

     

    A Surveiller.

    Si ça reste en l'état, à peu de choses près, ça va nous faire un beau triangle en face de la Terre pour le 21 décembre.

    NASA’s All Sky Fireball Network

     
     

    Intro:  The NASA All-sky Fireball Network is a network of cameras set up by the NASA Meteoroid Environment Office (MEO) with the goal of observing meteors brighter than the planet Venus, which are called fireballs.  The collected data will be used by the MEO in constructing models of the meteoroid environment, which are important to spacecraft designers.


    Network:  The network currently consists of 8 cameras, 6 of which are placed in locations in north Alabama, north Georgia, southern Tennessee, and southern North Carolina.  The remaining 2 are located in southern New Mexico. The network is growing all the time, with plans to place a total of 15 cameras in schools, science centers, and planetaria in the United States, predominantly east of the Mississippi River, where there are few such systems. 

     

    “What was that bright light in the sky last night?”

    Cameras:  Cameras in the network are specialized black and white video cameras with lenses that allow for a view of the whole night sky overhead. 


    Data:  The cameras have overlapping fields of view, which means that the same fireball can be detected by more than one camera.  This allows us to calculate the height of the fireball and how fast it is going.  We can even work out the orbit of the meteoroid responsible for creating the fireball, which gives us clues about whether it came from a comet or an asteroid.  If the fireball is traveling slow enough, and makes it low enough, it is possible that it can survive to the ground as a meteorite.


    This website:  This website displays fireball data in the form of images, movies, diagrams, and text files.  The data is organized by date.  Click on a date in the list on the left to see the fireballs detected that night.  If the page appears blank that means no fireballs were detected, probably because of bad weather. The website is automatically updated every morning at 8:00 am Central Time.  Only the last 3 weeks of data is available online.


    For more information, contact Dr. Bill Cooke or check out the MEO website.

    ça semble se confirmer ailleurs aussi ...

    December17, 2012 SEATTLE - Up to 12 inches of further snowfall is forecast for parts of northern New England - and a second wintry storm is crossing the U.S. in its wake, according to Weather Channel meteorologist Kevin Roth. The current snowfall in northern New York state and New England will continue through Tuesday night and into Wednesday, with as much as 15 inches possible in some areas. Meanwhile, another cross-country storm – Winter Storm Draco – was expected to bring heavy snow to the Northwest on Monday. The higher elevations of the Cascades will see as much as 2 to 3 feet of snow above 7000 ft, Weather.com reported, with significant accumulations below 3000 ft. The National Weather Service said the probability of “large amounts of snow remains high across the majority of windward facing slopes of the Pacific Northwest and portions of the Northern Rockies.” King5.com reported that the storm is expected to bring high winds to Western Washington and whiteout conditions to the west slopes of the Cascades and passes. The system is expected to move to the Southwest and Rockies Tuesday and Wednesday before bringing snow to the eastern half of the country later Wednesday through Friday. Roth added there would likely be a lake-effect snow threat behind the storm on Thursday and Friday. -NBC

    End of Mission: GRAIL Spacecraft Impact a Mountain on the Moon

    “So long, Ebb and Flow, and we thank you,” said GRAIL project manager David Lehman of NASA’s Jet Propulsion Laboratory after the twin GRAIL spacecraft completed a planned formation-flying double impact into the southern face of 2.5-kilometer- (1.5-mile-) tall mountain on a crater rim near the Moon’s north pole. Mission team members estimate the two spacecraft were traveling at a speed of 1.7 kilometers per second (3,760 mph), and likely broke apart on impact. NASA said that most of what remains of the washing machine-sized spacecraft are probably buried in shallow craters, and the size of those craters will hopefully be determined when NASA’s Lunar Reconnaissance Orbiter is able to image the impact site in about two weeks.

    NASA has honored the GRAIL team’s request to name Ebb and Flow’s impact sites after astronaut Sally Ride, who passed away earlier this year. She was America’s first woman in space and a member of the GRAIL mission team.

    A simulation of the GRAIL impacts:

    Impact occurred at 10:28:51 UTC (5:28:51 p.m. EST) and 10:29:21 UTC (5:29:21 p.m. EST). Right now it is night at the impact site, so sunlight should return within two weeks, enabling imaging of the site. LRO also took “before” images of the site during previous daylight orbits.

    The impact marked a successful end to the GRAIL(Gravity Recovery and Interior Laboratory)mission, which in just a 90-day prime mission generated the highest-resolution gravity field map of any celestial body — including Earth — and determined the inner crust of the Moon is nearly pulverized.

    “Ebb and Flow have removed a veil from the Moon,” said GRAIL principal investigator Maria Zuber during a televised commentary of the impacts today, adding that the mission will enable discoveries for years to come.

    Data from GRAIL’s extended mission and main science instruments are still being analyzed, and the findings will provide a better understanding of how Earth and other rocky planets in the solar system formed and evolved.

    GRAIL was NASA’s first planetary mission to carry cameras fully dedicated to education and public outreach. Ride, who died in July after a 17-month battle with pancreatic cancer, led GRAIL’s MoonKAM (Moon Knowledge Acquired by Middle School Students) Program through her company, Sally Ride Science. The camera took more than 115,000 total images of the lunar surface, and imaging targets were proposed by middle school students from across the country and the resulting images returned for them to study.

    “Sally was all about getting the job done, whether it be in exploring space, inspiring the next generation, or helping make the GRAIL mission the resounding success it is today,” said Zuber. “As we complete our lunar mission, we are proud we can honor Sally Ride’s contributions by naming this corner of the Moon after her.”

    Last Friday, Ebb and Flow, the two spacecraft comprising NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission, were commanded to descend into a lower orbit that would result in an impact Monday on a mountain near the Moon’s north pole.

    Fifty minutes prior to impact, the spacecraft fired their engines until the propellant was depleted. The maneuver was designed to determine precisely the amount of fuel remaining in the tanks. This will help NASA engineers validate computer models to improve predictions of fuel needs for future missions.

    “Ebb fired its engines for 4 minutes 3 seconds, and Flow fired its for 5 minutes 7 seconds,” Lehman. “It was one final important set of data from a mission that was filled with great science and engineering data.”

    Launched in September 2011, Ebb and Flow had been orbiting the moon since Jan. 1, 2012. The probes were intentionally crashed into the lunar surface because they did not have sufficient altitude or fuel to continue science operations.
