New evidence for oceans of water deep in the Earth @Science - 0 views

  •  
    Researchers from Northwestern University and the University of New Mexico report evidence for potentially oceans worth of water deep beneath the United States. Though not in the familiar liquid form-the ingredients for water are bound up in rock deep in the Earth's mantle-the discovery may represent the planet's largest water reservoir.

    While the new bacteria is pretty much useless, it would be interesting to see how base 3 genetic programming would turn out.

Stimulated mutual annihilation: How to make a gamma-ray laser with positronium - 1 views

  •  
    Theorists expect that positronium, a sort of 'atom' consisting of an electron and an anti-electron, can be used to make a powerful gamma-ray laser. Scientists now report detailed calculations of the dynamics of a positronium BEC. This work is the first to account for effects of collisions between different positronium species.

World's largest OTEC power plant planned for China - 1 views

  •  
    I wonder how much energy you can extract from the ocean in a responsible way... Mixing up different thermal layers would probably a quite an influence on ecology.
  •  
    The last available assessment report on the ecological impact seems to date from 1981 which would need to be brought up to current standards. On the other hand, this system could have a positive influence on fish population as deep cold water brings nutrients to the surface. The cold water could also be used to lower sea surface temperatures and affect hurricane genesis!

Testing shows using microwaves to propel a craft into space might work - 4 views

  •  
    A team of researchers at Colorado based Escape Dynamics is reporting that initial tests indicate that it might really be possible to launch space-planes into space using microwaves sent from the ground, to allow for a single stage spacecraft. If the idea pans out, the cost savings for sending satellites (or perhaps humans) into orbit could be considerable.
  •  
    Not very new, but a very slick video nonetheless! Will it work? I am not so sure whether "just engineering" applies in this case. The array of antenna's required is quite significant to compensate for beam losses. Wall plug efficiency is not that high therefore, then again.. solar energy is for free almost in the future so who cares.. let's go for it! :)

Failed strut caused SpaceX rocket blast: CEO Elon Musk - 3 views

  •  
    The SpaceX Falcon 9 explosion was caused by a failed strut that allowed a helium bottle to burst free inside the rocket's liquid oxygen tank, CEO Elon Musk said Monday. "One of those struts broke free during flight," Musk told reporters on a conference call to discuss the June 28 blast on what was supposed to be a routine cargo mission to the International Space Station.
  •  
    I guess this is how it starts as they mentioned they will inspect struts individually before each flight. Also for the space shuttle they believed a rapid inspection between launches would be feasible, but in the end there was a need for individual assessment almost. And we haven't even considered human spaceflight yet.
  •  
    as predicted, first failure, first inquiry board, first new safety procedures ... and certainly many more will follow and all will make sense but with the risk of loosing the competitive edge

Lotus Plant-Inspired Dust-Busting Shield To Protect Space Gear - 3 views

  • replicate to prevent dirt from accumulating on the surfaces of spacesuits, scientific instruments, robotic rovers, solar array panels and other hardware used to gather scientific data or carry out exploratory activities on other objects in the solar system
  • The team also is trying to partner with Northrop Grumman to add a biocide to the coating, which would kill bacteria that thrive and produce foul odors wherever people are confined to a small space for long periods, like the space station.
  •  
    We had some discussion about the Lotus-effect roughly two years ago. Zoe said that NASA surely worked on it. Well, she was right.

Russia To Spend 2 Bln Dollars For Space Clean-Up - 1 views

  • "The corporation promised to clean up the space in ten years by collecting about 600 defunct satellites on the same geosynchronous orbit and sinking them into the ocean subsequently,"
  • He said the cleaning satellite would work on nuclear power and be capable to work up to 15 years.
  • Energia said that the company would complete the cleaning satellite work-out and assembly by 2020 and test the device no later than in 2023.
  •  
    Hehe... as far as I know the Russians, they won't miss a chance to "clean up" a few enemy satellites too...

Power Law Explains Insurgent Violence - 1 views

  • To try to explain the mechanism behind these patterns, the team borrowed a simple computer model from economics. The model treated all insurgencies like a marketplace--groups of people constantly deciding whether to act. Rather than coordinating, the groups simply watch the news. The size of the carnage reported at any given time determines the probability that a group of a given size will strike next. Like clockwork, the attacks over the course of the conflict--from the smallest to the most deadly--have the same distribution.

NASA Administrator Promises Not to Cannibalize Science Budget - 0 views

  • Bolden didn't provide any direct answers to whether the agency would continue to send humans into space in the coming decade, as recommended by a report from a blue-ribbon panel last October. However, Bolden promised that the program would not be paid for through cuts to the agency's science budget, which has been cannibalized in recent years to support space flights. The auditorium erupted in applause. Bolden avoided getting into any specifics on the next generation of NASA manned spacecraft, a topic of hot debate.
