Radiation Belt Storms Probes Launched



 NASA hosted a two-day event for 50 social media followers on August 22-23, 2012, at NASA's Kennedy Space Center in Florida. NASA's twin Radiation Belt Storm Probes (RBSP) are scheduled to lift off aboard a United Launch Alliance Atlas V rocket at 4:08 a.m. on August 23. Designed for a two-year primary science mission in orbit around Earth, RBSP will provide insight into our planet's radiation belts, and help scientists predict changes in this critical region of space.

NASA's Radiation Belt Storm Probes blasted off from Cape Canaveral on August 30th, 2012. Bristling with sensors, the heavily-shielded spacecraft are on a 2-year mission to discover what makes the radiation belts so dangerous and so devilishly unpredictable.
"We've known about the Van Allen Belts for decades yet they continue to surprise us with unexpected storms of 'killer electrons' and other phenomena," says mission scientist David Sibeck, "The Storm Probes will help us understand what's going on out there."

Radiation Belt Storm Probes (RBSP)



The launch of an Atlas V carrying NASA's Radiation Belt Storm Probes (RBSP) payload was scrubbed today due to weather conditions associated with lightning, as well as cumulus and anvil clouds. With the unfavorable weather forecast as a result of Tropical Storm Isaac, the leadership team has decided to roll the Atlas V vehicle back to the Vertical Integration Facility to ensure the launch vehicle and twin RBSP spacecraft are secured and protected from inclement weather. Pending approval from the range, the launch is rescheduled to Thursday, Aug. 30 at 4:05 a.m. Eastern Daylight Time. SeeRBSP Launch Targeted for No Earlier Than Aug. 30



RBSP is being designed to help us understand the Sun’s influence on Earth and Near-Earth space by studying the Earth’s radiation belts on various scales of space and time. 

The instruments on NASA’s Living With a Star Program’s (LWS) Radiation Belt Storm Probes (RBSP) mission will provide the measurements needed to characterize and quantify the plasma processes that produce very energetic ions and relativistic electrons. The RBSP mission is part of the broader LWS program whose missions were conceived to explore fundamental processes that operate throughout the solar system and in particular those that generate hazardous space weather effects in the vicinity of Earth and phenomena that could impact solar system exploration. RBSP instruments will measure the properties of charged particles that comprise the Earth’s radiation belts, the plasma waves that interact with them, the large-scale electric fields that transport them, and the particle-guiding magnetic field. 

The two RBSP spacecraft will have nearly identical eccentric orbits. The orbits cover the entire radiation belt region and the two spacecraft lap each other several times over the course of the mission. The RBSP in situ measurements discriminate between spatial and temporal effects, and compare the effects of various proposed mechanisms for charged particle acceleration and loss. See: RBSP

Engineers at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., prepare to place Radiation Belt Storm Probes spacecraft "B" in a thermal-vacuum chamber, where they can make sure the propulsion system will stand up to the range of hot, cold and airless conditions RBSP will face in outer space. This round of testing took place in late October-early November 2010.

Sampex

SAMPEX, the Solar Anomalous and Magnetospheric Particle Explorer, was successfully launched by a Scout rocket on July 3, 1992. It is investigating the composition of local interstellar matter and solar material and the transport of magnetospheric charged particles into the Earth's atmosphere.

SAMPEX is a momentum-biased, sun-pointed spacecraft that maintains the experiment-view axis in a zenith direction as much as possible, especially while traversing the polar regions of the Earth. It points its solar array at the Sun by aiming the momentum vector toward the Sun and rotating the spacecraft one revolution per orbit about the Sun/spacecraft axis.




The Solar Anomalous and Magnetospheric Particle Explorer (SAMPEX) satellite was launched in July 1992 into a low earth orbit at an altitude of 520 by 670 km and 82 degrees inclination. The satellite far exceeded its expected three-year lifetime. It has primarily operated in a three-axis stabilized mode but has also been spun for limited periods. The satellite carries four instruments designed to measure the radiation environment of the Earth's magnetosphere.

SAMPEX was an international collaboration between NASA of the United States and Germany.[2] It was part of the Small Explorer program started in 1989[2]
SAMPEX science mission ended on June 30, 2004.[3]


The Crown of the Creation Syndrome

Innumerable suns exist; innumerable earths revolve around these suns in a manner similar to the way the seven planets revolve around our sun. Living beings inhabit these worlds. Giordano Bruno, 1584


The paper was very much appreciated by many of the author's colleagues[citation needed], even by very prominent ones, although it has also been criticized as being unscientific[citation needed], belonging more appropriately to the category of science fiction, by several other colleagues[citation needed]. The reason for this discrepancy, she says, is due solely to prejudice (similar to the prejudices regarding the biological evolution discovered by Darwin and his colleagues). As a matter of fact, Gato-Rivera even coined the term the Crown of the Creation Syndrome[citation needed], in her paper to explain this kind of prejudices, which she discusses in some detail.




DEMONSTRATION OF COMMUNICATION USING NEUTRINOS
 Beams of neutrinos have been proposed as a vehicle for communications under unusual circumstances, such as direct point-to-point global communication, communication with submarines, secure communications and interstellar communication. We report on the performance of a low-rate communications link established using the NuMI beam line and the MINERvA detector at Fermilab. The link achieved a decoded data rate of 0.1 bits/sec with a bit error rate of 1% over a distance of 1.035 km, including 240 m of earth.





Kapusta points out that the condensation temperature would be well below the cosmic background temperature, so it would be quite a feat to make this superfluid. However, Kapusta also notes that a sufficiently advanced civilization might use pulses of neutrino superfluid for long-distance communications. See: The right spin for a neutrino superfluid

Fractals and Antennas and The Economy




 The intuitive framework has to recognize that you have already worked the angles and that such intuition is gathered from all that has been worked. This contradicts what you are saying. I am not saying it is right just that I have seen this perspective in development with regard to scientists as they push through the wall that has separated them from moving on. This then details a whole set of new parameters in which the thinking mind can move forward with proposals.


 
 I never quite could get the economy either, until I understood the idea of Fractals as a gesture of the underlying pattern of all of the economy in expression. Of course that is my point of view.  I might of called it the algorithm before.

 The idea here is that all thing are expression of the underlying pattern and you might call the end result psychology or sociology of thinking and life as a result.

 It seems that the accumulated reference of mind as a place in it's evolution is to see that all the statistical information is already parametrized by the judgements in which you give them personally?

 Ultimately this is the setting for which your conclusions guide your perspective, yet, it is when we look back, one can choose too, "guide their brain?"



If you did not pick it up, Benoit was able to reduce the economy too, and used an inductive deductive facility in regard to what is self evident. But I would point out what you might have interpreted as illusory in terms of the graph he sees on the board was instrumental to his penetrating the pattern in the economy.

Just raising the name of Nassim Nicholas Taleb and the idea of the Black Swan in relation to the basis of the economy Benoit raises deeper questions and does garner a look for me. I don't know what to expects is opening up the door to understanding more about such erudition's but they are with regard to the economy.




 Taleb was collaborating with Benoit Mandelbrot on a general theory of risk management Collaborations

A simple assumption about heads and tails, leads to bell curves and such?

Taleb, N. N. (2008) Edge article: Real Life is Not a Casino

So you are looking at both sides of the coin.

More on the Black Swan here.



 While these writings are disparate pieces, do they indeed come together under this post book review?? As a scientist and mathematics person are you not intrigued about "the pattern?" I was shocked.....yet is made sense.

Now Nassim adds dimension to the subject. "He calls for cancellation of the Nobel Memorial Prize in Economics, saying that the damage from economic theories can be devastating".

Game theory if you know how it works it is used in all types of negotiation.

Sarah Parcak: Archeology from space and more


 Sarah Parcak: Archeology from space


 Sarah Parcak is an archaeologist and Egyptologist, and specializes in making the invisible past visible using 21st-century satellite technology. She co-directs the Survey and Excavation Projects in the Fayoum, Sinai, and Egypt's East Delta with her husband, Dr. Greg Mumford. Parcak is the author of Satellite Remote Sensing for Archaeology, the first methods book on satellite archaeology, and her work has seeded several TV documentaries. She founded and directs the Laboratory for Global Observation at the University of Alabama at Birmingham.




While most Google Earth hobbyists are satisfied with a bit of snapping and geotagging, some have far loftier ambitions. Satellite archaeologist Angela Micol thinks she's discovered the locations of some of Egypt's lost pyramids, buried for centuries under the earth, including a three-in-a-line arrangement similar to those on the Giza Plateau. Egyptologists have already confirmed that the secret locations are undiscovered, so now it's down to scientists in the field to determine if it's worth calling the diggers in.

Worldwide LHC Computing

Grid Cafe

 Individual computers also become more powerful, which means that computer grids are increasingly able to solve increasingly complex problems. All this computing power helps our scientists find solutions to the big questions, like climate change and sustainable power.


The mission of the WLCG project is to provide global computing resources to store, distribute and analyse the ~25 Petabytes (25 million Gigabytes) of data annually generated by the Large Hadron Collider (LHC) at CERN on the Franco-Swiss border.

Current WLCG sites

Architecture of Trigger System

Block diagram of front-end electronics and its interface to Trigger, DAQ and Detector Control System.
Detailed descriptions of the front-end architecture can be found in the following LHCb notes:
EDMS715154, Requirements to the L1 front-end electronics.
LHCb-2001-014, Requirements to the L0 front-end electronics.
EDMS 692583, Test, time alignment, calibration and monitoring in the LHCb front-end electronics.




The HLT (High Level Trigger) have access to all data. At the 1 MHz output rate of Level-0 the remaining analogue data is digitized and all data is stored for the time needed to process the Level algorithm. This algorithm is implemented on a online trigger farm composed of up to 2000 PCs.

The HLT algorithm is divided in two sequential phases called HLT1 and HLT2. HLT1 applies a progressive, partial reconstruction seeded by the L0 candidates. Different reconstruction sequences (called alleys) with different algorithms and selection cuts are applied according to the L0 candidate type. The HLT run very complex physics tests to look for specific signatures, for instance matching tracks to hits in the muon chambers, or spotting photons through their high energy but lack of charge. Overall, from every one hundred thousand events per second they select just dizaines of events and the remaining dizaines of thousands are thrown out. We are left with only the collision events that might teach us something new about physics.


 With this telescope, Jill’s vision, and the power of open-source initiatives, we were able to globalize the search for extraterrestrial intelligence. Because we don’t know what a new signal will look like, it’s hard to create an algorithm to find it, and our own eyes actually work better than computers.See:The search for cosmic company goes on
