    Really interesting bit hidden in the last paragraph: Monitoring coral bleaching from space with Envisat penetrating down to a depth of 10 m "[...] Envisat's Medium Resolution Imaging Spectrometer sensor can detect coral bleaching down to depths of ten metres, meaning Envisat could potentially map coral bleaching on a global scale."

    No, it can't :-) Since 8 April 2012 Envisat is a proud holder of the title of one of the biggest pieces of space junk out there in LEO...

    admittedly correct, so the past tense would have been a more appropriate choice... Nevertheless, plenty of data to look back at and Sentinel-3 will launch eventually! ;)

phy higgs particles

shared by pacome delva on 05 Feb 10 - Cached
  • to reduce the chances of the LHC being derailed again by a similar accident, physicists at the Geneva lab have decided to run the collider at just half its design energy for the next 18-24 months.
  • Once the 7 TeV run is over, CERN will shut the LHC down in 2012 for a year or more to prepare it to go straight to maximum-energy 14 TeV collisions in 2013. This will be a complex job that will involve replacing some 10,000 superconducting magnet connections with more robust ones.
  • choosing to stay at lower energies is a big price to pay in terms of the Higgs search. "We will need more than twice the data at 7 TeV compared to that needed at 10 TeV to reach the same discovery potential," she says. "At this energy we can at best expect to exclude a Higgs with a mass between 155 and 175 GeV."

    no Higgs boson before 2013... and a replacement of 10,000 superconducting magnet connections ! Reminds me of the the gravitational detectors... no detection before an upgrade in 2013...! There are the big announcements to make the cash flow... and reality !

    Higgs is almost 81, so he should better invest in his health if he wants the Nobel prize... But who cares, it's another 5 years window where high-energy theorists can produce nonsense with no experimental evidence. They should be happy!

tech exploration hopping

shared by Juxi Leitner on 02 May 10 - Cached
  • The testing of the second-generation lunar hopper is being carried out under the supervision of engineers from the nearby Draper Laboratory with an eye toward competing for the Google Lunar X Prize in 2012.
  • Although planetary rovers are not new, the hopper concept could add a new dimension to robotic planetary exploration, one that Tuohy said could inspire a new generation of engineers, technologists and scientists.

    Greenwich could lose its place at the centre of global time if a move to "atomic time" is voted in by the International Telecommunication Union in Geneva in January 2012.

    The article says it can lead to abandoning the Daylight Wasting Time in winter, so if that's the case, I'm definitely for.
  • pacome delva on 07 Nov 11
     
    Haha this is really a British article... Already since 1972 we don't use GMT but UTC, which is based on atomic clocks. However British continue to call it GMT... The question is to drop the leap second in UTC, and France is definitely for this change (for scientific motives of course...;) I don't see how this is connected to winter time however... And they shouldn't worry Greenwich is still the beginning of the world with 0 degree longitude !
  • Ma Ru on 07 Nov 11
     
    "the end of GMT as an international standard could accelerate the move to keep British Summer Time into the winter, letting us have lighter evenings." As I understand it, if GMT looses its "prestigious" status, then it would be easier to push through all-year BST in UK.

    Hasta la vista, baby. A real-life T-1000, the shape-shifting liquid-metal robot from Terminator 2, is a step closer, thanks to a self-powered liquid metal motor. The device is surprisingly simple: just a drop of metal alloy made mostly of gallium - which is liquid at just under 30 °C - with some indium and tin mixed in.

    Jarvis could make it, add a power supply and aquarium and we are off :)

    NASA Releases Tool Enabling Citizen Scientists to Examine Asteroid Vesta Vesta Trek is a free, web-based application that provides detailed visualizations of Vesta, one of the largest asteroids in our solar system. NASA's Dawn spacecraft studied Vesta from July 2011 to September 2012. Data gathered from multiple instruments aboard Dawn have been compiled into Vesta Trek's user-friendly set of tools, enabling citizen scientists and students to study the asteroid's features. The application includes: -- Interactive maps with the ability to overlay a growing range of data sets including topography, mineralogy, abundance of elements and geology, as well as analysis tools for measuring the diameters, heights and depths of surface features and more. -- 3-D printer-exportable topography so users can print physical models of Vesta's surface. -- Standard keyboard gaming controls to manoever a first-person visualization of "flying" across the surface of the asteroid. "There's nothing like seeing something with your own eyes, but these types of detailed data-visualizations are the next best thing," said Kristen Erickson, Director, Science Engagement and Partnerships at NASA Headquarters in Washington DC.
