Pluto - New horizons + 37 days.
Flyby Elapsed Time: 37 Days 4 Hours 29 Minutes 2 Seconds. Spacecraft is now at distance from Pluto: 44,290,525 km. Let´s have a look now on data send in August 12, 2015 by the LORRI instrument.
Scientists Study Nitrogen Provision for Pluto’s Atmosphere
The latest data from NASA’s New Horizons spacecraft reveal diverse features on Pluto’s surface and an atmosphere dominated by nitrogen gas. However, Pluto’s small mass allows hundreds of tons of atmospheric nitrogen to escape into space each hour. 
So where does all this nitrogen come from? Kelsi Singer, a postdoctoral researcher at Southwest Research Institute, and her mentor Alan Stern, New Horizons principal investigator and SwRI associate vice president, outlined likely sources in a paper titled, “On the Provenance of Pluto’s Nitrogen.” The Astrophysical Journal Letters accepted the paper for publication on July 15, just a day after the spacecraft’s closest encounter with the icy dwarf planet. 
“More nitrogen has to come from somewhere to resupply both the nitrogen ice that is moving around Pluto’s surface in seasonal cycles, and the nitrogen that is escaping off the top of the atmosphere as the result of heating by ultraviolet light from the Sun,” said Singer. 
Singer and Stern looked at a number of different ways that nitrogen might be resupplied. They wondered if comets could deliver enough nitrogen to Pluto’s surface to resupply what is escaping its atmosphere. They also looked at whether craters made by the comets hitting the surface could excavate enough nitrogen – but that would require a very deep layer of nitrogen ice at the surface, which is not proven. The team also studied whether craters could expose more surface area, by punching through surface deposits that would likely be built up over time.   
“We found that all of these effects, which are the major ones from cratering, do not seem to supply enough nitrogen to supply the escaping atmosphere over time,” continued Singer. “While it’s possible that the escape rate was not as high in the past as it is now, we think geologic activity is helping out by bringing nitrogen up from Pluto’s interior.” 
And while the data weren’t in before this paper was written, the newest images of Pluto show land forms that suggest heat is rising beneath the surface, with troughs of dark matter either collecting, or bubbling up, between flat segments of crust, which could be related. 
“Our pre-flyby prediction, made when we submitted the paper, is that it’s most likely that Pluto is actively resupplying nitrogen from its interior to its surface, possibly meaning the presence of ongoing geysers or cryovolcanism,” said Stern. “As data from New Horizons comes in, we will be very interested to see if this proves true. 
” New Horizons is part of NASA’s New Frontiers Program, managed by the agency’s Marshall Space Flight Center in Huntsville, Ala. The Johns Hopkins University Applied Physics Laboratory in Laurel, Md., designed, built, and operates the New Horizons spacecraft and manages the mission for NASA’s Science Mission Directorate. SwRI leads the science mission, payload operations, and encounter science planning.

NASA's Next Megarocket Could Launch Mission to Europa - Video Space Com 7.15

Hi passengers !
The huge rocket NASA is developing to get astronauts to an asteroid, Mars and other distant destinations should also greatly aid robotic exploration efforts, members of Congress were told Tuesday (July 28). 
The Space Launch System (SLS) megarocket, scheduled to fly for the first time in 2018, will blast unmanned spacecraft toward their targets at incredible speeds, dramatically reducing interplanetary travel times, said John Grunsfeld, associate administrator of NASA's Science Mission Directorate. 
"My view is that the Space Launch System will be transformative for science," Grunsfeld told members of the U.S. House of Representatives' Science, Space and Technology Committee during a hearing Tuesday entitled "Exploration of the Solar System: From Mercury to Pluto and Beyond."
SLS Megarocket can reach Jupiter´s moon ''Europa'' in three years ! 
As an example, Grunsfeld cited NASA's planned flyby mission to Jupiter's ocean-harboring moon Europa, which the agency aims to launch in the early to mid-2020s. Using SLS instead of currently available rockets would slash the probe's journey to the Jupiter system from about eight years to less than three years, Grunsfeld said. (Mission team members are developing the Europa flyby craft to fit on a variety of different launch vehicles, including SLS.) 
"This is one of those rare cases where time really is money," he said. "In that extra cruise time, you know, we have to maintain an engineering team and a science team and a spacecraft while it's in cruise, even if we hibernate. And that's something that also delays the science. 
" NASA's New Horizons spacecraft, which just two weeks ago performed history's first-ever flyby of Pluto, was launched by a United Launch Alliance Atlas V rocket. New Horizons weighed just 1,050 lbs. (480 kilograms) fully fueled, but its mission still required the most powerful variant of the Atlas V, Grunsfeld said. 
And New Horizons zoomed straight through the Pluto system at high speed for a one-time flyby. Spacecraft that linger around a celestial body — such as the Europa probe, which will perform at least 45 flybys of Europa from Jupiter orbit — cannot travel so light, said New Horizons principal investigator Alan Stern, of the Southwest Research Institute in Boulder, Colorado. 
For orbiters and surface craft, "you need to carry a lot of fuel, and there's no way to lighten the fuel; you need it so you can come to a stop on that planetary surface or in orbit," Stern told committee members during today's hearing. "SLS is going to really help us enable [such] space missions, including — I hope one day — a return to the Pluto system and the Kuiper Belt." 
SLS could also aid deep-space astronomy, by allowing larger and more powerful space telescopes to be launched, Grunsfeld said. 
The rocket could launch entire space observatories, or perhaps "parts that astronauts could assemble to build a telescope that could search for atmospheres around nearby [alien] worlds," Grunsfeld said. 
In its initial configuration, SLS will stand 321 feet (98 meters) tall and be capable of lofting 77 tons (70,000 kg) to low-Earth orbit. The rocket will provide about 10 percent more thrust than NASA's famous Saturn V rocket, which blasted astronauts toward the moon, agency officials say. 
But NASA also plans an "evolved" 384-foot-tall (117 m) SLS version that can launch 143 tons (130,000 kg) and generate 20 percent more thrust than the Saturn V.
SLS and the Orion capsule, which is also in development, will help get astronauts to a near-Earth asteroid and Mars, NASA officials say. 
The first launch of SLS in 2018 will send an uncrewed Orion on a journey around the moon. The rocket and capsule should fly astronauts together for the first time in 2021 or so. The current plan calls for sending these crewmembers out to rendezvous with a near-Earth asteroid that a robotic probe has dragged into orbit around the moon.

'Voyager 2015 : Journey to the Stars'' - Video Space Rip 4.13

Hi passengers !
Remembering today the longest mission ever made by robotised human spacecrafts : Voyager 1 & Voyager 2 have both inspired many of numeric reports on this blogger, telling stories about space missions done since the first orbit of Sputnik in April 12, 1957 and trying to understand what astrophysics explains about the Cosmos surrounding us everywhere in 2015...
 Jean gregorio presents now this interesting documentary seen on Youtube ''Voyager, journey to the stars'' produced by Space Rip. Ttitle : Cosmic Journeys edited on April 6, 2013.
Cosmic Journeys - Voyager Journey to the Stars
Cosmic Journeys examines the great promise of the Voyager mission and where it will lead us in our grand ambition to move out beyond our home planet. The two Voyager spacecraft are part of an ancient quest to push beyond our boundaries... to see what lies beyond the horizon. Now tens of billions of kilometers from Earth, two spacecraft are streaking out into the void. What will we learn about the Galaxy, the Universe, and ourselves from Voyager's epic Journey to the stars? 
December 19, 1972... the splashdown of the Apollo 17 crew capsule marked the end of the golden age of manned spaceflight. The Mercury.... Gemini... and Apollo programs had proven that we could send people into space... To orbit the Earth.... Fly out beyond our planet... Then land on the moon and walk among its ancient crater. 
The collective will to send people beyond our planet faded in times of economic uncertainty, war, and shifting priorities. And yet, just five years after Apollo ended, scientists launched a new vision that was just as profound and even more far-reaching. 
It didn't all go smoothly. Early computer problems threatened to doom Voyager 2. Then its radio receiver failed, forcing engineers to use a back up. Now, after more than three and a half decades of successful operations, the twin spacecraft are sending back information on their flight into interstellar space. Along the way, they have revealed a solar system rich beyond our imagining. 
The journey was made possible by a rare alignment of the planets, a configuration that occurs only once every 176 years. That enabled the craft to go from planet to planet, accelerating as they entered the gravitational field of one, then flying out to the next. The Voyagers carried a battery of scientific equipment to collect data on the unknown worlds in their path. That included a pair of vidicom cameras, and a data transfer rate slower than a dialup modem.

New Horizons 2015 +12 days - Flying over Pluto - Video Nasa News 7.15

Hi passengers !
This simulated flyover of Pluto’s Norgay Montes (Norgay Mountains) and Sputnik Planum (Sputnik Plain) was created from New Horizons closest-approach images. 
Norgay Montes have been informally named for Tenzing Norgay, one of the first two humans to reach the summit of Mount Everest. 
Sputnik Planum is informally named for Earth’s first artificial satellite. 
The images were acquired by the Long Range Reconnaissance Imager (LORRI) on July 14 from a distance of 48,000 miles (77,000 kilometers). 
Features as small as a half-mile (1 kilometer) across are visible.
12 days after the closest approach of Pluto/Charon Biplanetary system, data from the instruments installed on New Horizons spacecraft are still growing our knowledge about far distances objects out of the solar system. 
Presenting the last news from NASA with this following numeric report and a playslist of 13 videos to read, watch and listen for a better understanding of how the cosmos work ?
New Horizons Discovers Flowing Ices on Pluto...
NASA’s New Horizons mission has found evidence of exotic ices flowing across Pluto’s surface, at the left edge of its bright heart-shaped area. New close-up images from the spacecraft’s Long-Range Reconnaissance Imager (LORRI) reveal signs of recent geologic activity, something scientists hoped to find but didn’t expect. “We’ve only seen surfaces like this on active worlds like Earth and Mars,” said mission co-investigator John Spencer of SwRI. “I'm really smiling.” The new close-up images show fascinating detail within the Texas-sized plain (informally named Sputnik Planum) that lies within the western half of Pluto’s heart-shaped region, known as Tombaugh Regio. There, a sheet of ice clearly appears to have flowed—and may still be flowing—in a manner similar to glaciers on Earth.
Meanwhile, New Horizons scientists are using enhanced color images (see below) to detect differences in the composition and texture of Pluto’s surface. When close-up images are combined with color data from the Ralph instrument, they paint a new and surprising portrait of Pluto in which a global pattern of zones vary by latitude. The darkest terrains appear at the equator, mid-tones are the norm at mid-latitudes, and a brighter icy expanse dominates the north polar region. The New Horizons science team is interpreting this pattern to be the result of seasonal transport of ices from equator to pole. This pattern is dramatically interrupted by the bright “beating heart” of Pluto.
The “heart of the heart,” Sputnik Planum, is suggestive of a reservoir of ices. The two bluish-white “lobes” that extend to the southwest and northeast of the “heart” may represent exotic ices being transported away from Sputnik Planum. Additionally, new compositional data from New Horizons’ Ralph instrument indicate that the center of Sputnik Planum is rich in nitrogen, carbon monoxide, and methane ices. “At Pluto’s temperatures of minus-390 degrees Fahrenheit, these ices can flow like a glacier,” said Bill McKinnon, of Washington University in St. Louis, deputy leader of the New Horizons Geology, Geophysics and Imaging team. In the southernmost region of the heart, adjacent to the dark equatorial region, it appears that ancient, heavily-cratered terrain (informally named “Cthulhu Regio”) has been invaded by much newer icy deposits.
The newly-discovered range of mountains rises one mile (1.6 kilometers) above the surrounding plains, similar to the height of the Appalachian Mountains in the United States. These peaks have been informally named Hillary Montes (Hillary Mountains) for Sir Edmund Hillary, who first summited Mount Everest with Tenzing Norgay in 1953. “For many years, we referred to Pluto as the Everest of planetary exploration,” said New Horizons Principal Investigator Alan Stern of the Southwest Research Institute, Boulder, Colorado. “It’s fitting that the two climbers who first summited Earth’s highest mountain, Edmund Hillary and Tenzing Norgay, now have their names on this new Everest.” View a simulated flyover using New Horizons’ close-approach images of Sputnik Planum and Pluto’s newly-discovered mountain range – Hillary Montes, in the video below.

Plasma Cosmology VS Big Bang Theory EXPLAINED - Video Santos Cruz 6.15

Hi passengers !
Santos Cruz 
With the flyby of spacecraft «New Horizons» trhough the Pluto/Charon binary planet system and it four (4) moons, few new findings in Plasma Cosmology have opened thousands of questions about the real constitution of the Universe and how this knowledge is bringing us to an higher understanding of what really is surrounding us.
Documentary added on June 12, 2015 
«These guys are the real deal...they explained about real astronomy and important things happened in the universe billions of years ago by moving further than hypothesis... 
This is the only way i can promote these so called alternative science...but for me their explanations are much better than mainstream (standard) science...»
Science and Ideology
Although The BBT (Big Bang Theory) can claim to be the dominant cosmology just now, many increasingly regard it as little more than ideology. There are no lack of web resources devoted to its demise, so, rather than going over too much old ground, below is a summary of some of its more controversial claims.
The CMB (Cosmic Microwave Background)
Big Bang supporters are fond of claiming CMB radiation as conclusive evidence for their theory, but these claims begin to look somewhat revisionist in the light of the following facts. 
The background temperature of space was predicted by Guillaume, Eddington, Regener, Nernst, Herzberg, Finlay-Freundlich and Max Born, based on a universe without expansion, and prior to the discovery of the CMB. 
Their predictions were far more accurate than models based on the Big Bang. In 1965, two young radio astronomers, Arno Penzias and Robert Wilson, accidentally discovered the CMB using a small horn antenna. 
This discovery was quickly seized upon by Big Bang supporters and they were later awarded the Nobel Prize!
The role of Plasma in The Universe
Plasma cosmology has gone beyond hypothesis and analysis. There are problems with part three, of course, experimentation on universal scales, but the fact is that plasmas are highly scalable, and super-computing capabilities have enabled us to model plasma behaviours on galactic scales ... utilising only a few simple formulae. 
These models are consistent with reality. Big Bang cosmology, by contrast, fails to adequately account for the 'clumpiness' and filamentary structures that we observe. Plasma cosmology does NOT rely on abstract mathematical modelling or an increasing array of exotic hypotheticals like Dark Matter and Dark Energy !

New Horizons 2015 + 9 days - Flyby over Pluto - Video Nasa News 7.15

Hi passengers !
Presenting the NASA conference about the new horizons findings after the fyby over Pluto this last July 14, 2015.
Flyby Elapsed Time: 9 Days 2 Hours 46 Minutes 9 Seconds 
Beginning 14 July 2015, 11:49:57 UTC
New Horizons Finds Second Mountain Range in Pluto's 'Heart'
Pluto’s icy mountains have company. NASA’s New Horizons mission has discovered a new, apparently less lofty mountain range on the lower-left edge of Pluto’s best known feature, the bright, heart-shaped region named Tombaugh Regio (Tombaugh Region). 
These newly-discovered frozen peaks are estimated to be one-half mile to one mile (1-1.5 kilometers) high, about the same height as the United States’ Appalachian Mountains. The Norgay Montes (Norgay Mountains) discovered by New Horizons on July 15 more closely approximate the height of the taller Rocky Mountains. 
The new range is just west of the region within Pluto’s heart called Sputnik Planum (Sputnik Plain). The peaks lie some 68 miles (110 kilometers) northwest of Norgay Montes. This newest image further illustrates the remarkably well-defined topography along the western edge of Tombaugh Regio. 
“There is a pronounced difference in texture between the younger, frozen plains to the east and the dark, heavily-cratered terrain to the west,” said Jeff Moore, leader of the New Horizons Geology, Geophysics and Imaging Team (GGI) at NASA’s Ames Research Center in Moffett Field, California. “There’s a complex interaction going on between the bright and the dark materials that we’re still trying to understand.” While Sputnik Planum is believed to be relatively young in geological terms – perhaps less than 100 million years old — the darker region probably dates back billions of years. 
Moore notes that the bright, sediment-like material appears to be filling in old craters (for example, the bright circular feature to the lower left of center). This image was acquired by the Long Range Reconnaissance Imager (LORRI) on July 14 from a distance of 48,000 miles (77,000 kilometers) and sent back to Earth on July 20. 
Features as small as a half-mile (1 kilometer) across are visible. The names of features on Pluto have all been given on an informal basis by the New Horizons team.

Dawn 2015 -'intriguing' pyramid on dwarf planet Ceres - Video The Cosmos News 6.15

Hi Passengers !
New images taken by Nasa's Dawn spacecraft have captured an odd, pyramid-shaped peak protruding from the flat surface of Ceres. 
The craft has been observing the dwarf planet, which lies in the distant asteroid belt between Mars and Jupiter, from a second mapping orbit of 4,400km (2,700 miles). The latest images reveal an unusual, pointed mountain jutting from an otherwise smooth stretch of the landscape, estimated to be around 5km (3 miles) tall.
 'Intriguing' pyramid observed on dwarf planet Ceres
Although there are yet to be any explanations for the pyramid's origins, previous studies of the planet have revealed a whole host of active phenomena on its surface, from landslides and rock flows to remnants of crumbled (natural) structures. 
A series of currently inexplicable bright spots have also added to the planet's manifold mysteries. The white spots were previously seen on an earlier mapping of Ceres, but the latest view has captured eight smaller spots enigmatically scattered across the surface of a 55-mile-wide crater. 
Nasa scientists believe that the spots are caused by a highly reflective material, such as salt deposits or ice, but it's hoped that further study by Dawn's visible and infrared mapping spectrometer -- which can identify specific minerals by analysing how light is reflected -- will yield some more definitive answers. 
Carol Raymond, deputy principal investigator for the Dawn mission, commented: "The surface of Ceres has revealed many interesting and unique features. For example, icy moons in the outer solar system have craters with central pits, but on Ceres central pits in large craters are much more common."

Plasma cosmology - The universe is electric - Video Santos Cruz 4.15

Hi passengers !
Tonight i present this documentary of 63 mn about real astronophysics and explaining important things happened on earth thousands of years ago. This alternative science is not yet learned in school but gives a better explanation than the mainstream standart science over the observable universe.
Plasma cosmology : 
It´s a non-standard cosmology whose central postulate is that the dynamics of ionized gases and plasmas play important, if not dominant, roles in the physics of the universe beyond the Solar System. 
This is contrary to the general consensus by cosmologists and astrophysicists which strongly supports that astronomical bodies and structures in the universe are mostly influenced by gravity, Einstein's theory of general relativity, and quantum mechanics.
These can be used to explain the origin, structure and evolution of the universe on cosmic scales. As of 2015, the vast majority of researchers openly reject plasma cosmology because it does not match modern observations of astrophysical phenomena or accepted cosmological theory.
The Electric Universe :
It´s a variant of Plasma Cosmology, and it is necessary to differentiate between the two. While they share more similarities than differences, it should be noted that EU ideas tend to go a step further than the generally more conservative approach of Plasma Cosmology. 
While both viewpoints permit many ideas previously excluded by Big Bang Cosmology, The Electric Universe looks at the bigger picture, and promotes more radical ideas about the role of electricity in the universe, from ancient mythology to the mind-body connection. 
Both PC and EU proponents acknowledge the fact that space is NOT electrically neutral, a fact largely denied in conventional astronomy...
