[VIDEO] 600 Days & Counting: US Air Force’s Unmanned Space Plane, X-37B, on Verge of Breaking Record for Longest Time in SpacePosted: January 16, 2017
It marks the first time for that stealth aircraft to be stationed overseas.
The US Marine Corps said it has sent a squadron of F-35B fighter jets to Japan, marking the first operational overseas deployment for the controversial aircraft that is under scrutiny from president-elect Donald Trump.
The deployment of the 10 planes to Marine Corps Air Station Iwakuni on Honshu Island marks a major milestone for the F-35, which has been bedeviled by technical glitches and soaring cost overruns.
With a current development and acquisition price tag already at $379 billion for a total of 2,443 F-35 aircraft, Lockheed Martin’s F-35 is the most expensive plane in history, and costs are set to go higher still.
The Marines’s version of the plane, known as the F-35B, is capable of conducting short takeoffs and vertical landings.
Trump last month sent shockwaves through the aerospace industry when he tweeted that he wanted rival Boeing to price out a possible alternative.
“Based on the tremendous cost and cost overruns of the Lockheed Martin F-35, I have asked Boeing to price-out a comparable F-18 Super Hornet!” Trump tweeted December 22.
The F/A-18 Super Hornet does not have stealth capabilities and has been in use since the late 1990s.
Once servicing, maintenance and other costs for the F-35 are factored in over the aircraft’s lifespan through 2070, overall program costs have been projected to rise to as much as $1.5 trillion.
Proponents of the F-35 tout its speed, close air-support capabilities, airborne agility and a massive array of sensors giving pilots unparalleled access to information. Read the rest of this entry »
Paris (AFP) – The Moon, our planet’s constant companion for some 4.5 billion years, may have been forged by a rash of smaller bodies smashing into an embryonic Earth, researchers said Monday.
Such a bombardment birth would explain a major inconsistency in the prevailing hypothesis that the Moon splintered off in a single, giant impact between Earth and a Mars-sized celestial body.
“The multiple impact scenario is a more ‘natural’ way of explaining the formation of the Moon.”
In such a scenario, scientists expect that about a fifth of the Moon’s material would have come from Earth and the rest from the impacting body.
Yet, the makeup of the Earth and the Moon are near identical — an improbability that has long perplexed backers of the single-impact hypothesis.
“In the early stages of the Solar System, impacts were very abundant, therefore it is more natural that several common impactors formed the Moon rather than one special one.”
“The multiple impact scenario is a more ‘natural’ way of explaining the formation of the Moon,” said Raluca Rufu of the Weizmann Institute of Science in Rehovot, who co-authored the new study published in the journal Nature Geoscience.
Such multiple hits would have excavated more Earth material than a single one, which means the moonlets would more closely resemble our planet’s composition, said the study authors. Read the rest of this entry »
[VIDEO] Iranian Jet Picking Up Obama Administration’s Prisoner Release Ransom Payment of $400 Million in Swiss FrancsPosted: December 29, 2016
A video from Jan. 17, 2016, shows an Iranian government jet as it departs Geneva, Switzerland, with $400 million in Swiss francs from the Obama administration. It was the same day four American prisoners were released from Iran.
It May Not Feel Like Anything To Be an Alien
Susan Schneider writes: Humans are probably not the greatest intelligences in the universe. Earth is a relatively young planet and the oldest civilizations could be billions of years older than us. But even on Earth, Homo sapiens may not be the most intelligent species for that much longer.
“Why would nonconscious machines have the same value we place on biological intelligence?”
The world Go, chess, and Jeopardy champions are now all AIs. AI is projected to outmode many human professions within the next few decades. And given the rapid pace of its development, AI may soon advance to artificial general intelligence—intelligence that, like human intelligence, can combine insights from different topic areas and display flexibility and common sense. From there it is a short leap to superintelligent AI, which is smarter than humans in every respect, even those that now seem firmly in the human domain, such as scientific reasoning and social skills. Each of us alive today may be one of the last rungs on the evolutionary ladder that leads from the first living cell to synthetic intelligence.
What we are only beginning to realize is that these two forms of superhuman intelligence—alien and artificial—may not be so distinct. The technological developments we are witnessing today may have all happened before, elsewhere in the universe. The transition from biological to synthetic intelligence may be a general pattern, instantiated over and over, throughout the cosmos. The universe’s greatest intelligences may be postbiological, having grown out of civilizations that were once biological. (This is a view I share with Paul Davies, Steven Dick, Martin Rees, and Seth Shostak, among others.) To judge from the human experience—the only example we have—the transition from biological to postbiological may take only a few hundred years.
I prefer the term “postbiological” to “artificial” because the contrast between biological and synthetic is not very sharp. Consider a biological mind that achieves superintelligence through purely biological enhancements, such as nanotechnologically enhanced neural minicolumns. This creature would be postbiological, although perhaps many wouldn’t call it an “AI.” Or consider a computronium that is built out of purely biological materials, like the Cylon Raider in the reimagined Battlestar Galactica TV series.
The key point is that there is no reason to expect humans to be the highest form of intelligence there is. Our brains evolved for specific environments and are greatly constrained by chemistry and historical contingencies. But technology has opened up a vast design space, offering new materials and modes of operation, as well as new ways to explore that space at a rate much faster than traditional biological evolution. And I think we already see reasons why synthetic intelligence will outperform us.
Silicon microchips already seem to be a better medium for information processing than groups of neurons. Neurons reach a peak speed of about 200 hertz, compared to gigahertz for the transistors in current microprocessors. Although the human brain is still far more intelligent than a computer, machines have almost unlimited room for improvement. It may not be long before they can be engineered to match or even exceed the intelligence of the human brain through reverse-engineering the brain and improving upon its algorithms, or through some combination of reverse engineering and judicious algorithms that aren’t based on the workings of the human brain.
In addition, an AI can be downloaded to multiple locations at once, is easily backed up and modified, and can survive under conditions that biological life has trouble with, including interstellar travel. Our measly brains are limited by cranial volume and metabolism; superintelligent AI, in stark contrast, could extend its reach across the Internet and even set up a Galaxy-wide computronium, utilizing all the matter within our galaxy to maximize computations. There is simply no contest. Superintelligent AI would be far more durable than us.
Suppose I am right. Suppose that intelligent life out there is postbiological. What should we make of this? Here, current debates over AI on Earth are telling. Two of the main points of contention—the so-called control problem and the nature of subjective experience—affect our understanding of what other alien civilizations may be like, and what they may do to us when we finally meet.
Ray Kurzweil takes an optimistic view of the postbiological phase of evolution, suggesting that humanity will merge with machines, reaching a magnificent technotopia. But Stephen Hawking, Bill Gates, Elon Musk, and others have expressed the concern that humans could lose control of superintelligent AI, as it can rewrite its own programming and outthink any control measures that we build in. This has been called the “control problem”—the problem of how we can control an AI that is both inscrutable and vastly intellectually superior to us. Read the rest of this entry »

On December 24th, 1968, Apollo 8 made its final pass around the moon and the crew, in turn, sent home this message:
“We are now approaching lunar sunrise, and for all the people back on Earth, the crew of Apollo 8 has a message that we would like to send to you.
‘In the beginning God created the heaven and the earth.
And the earth was without form, and void; and darkness was upon the face of the deep.
And the Spirit of God moved upon the face of the waters. And God said, Let there be light: and there was light.
And God saw the light, that it was good: and God divided the light from the darkness.'”
“And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.
And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so.
And God called the firmament Heaven. And the evening and the morning were the second day.”
Japan is leaping into space resources, agreeing to work with a robotic-exploration company to create a blueprint for an industry to extract resources from the moon that would enable more extensive space exploration.
It can reach an altitude of over 6,500 feet and travel at over 65 miles per hour.
This film documents the selection of the original seven astronauts for Project Mercury: Lieutenant Malcolm S. (Scott) Carpenter, Captain Leroy G. (Gordon) Cooper, Lieutenant Colonel John H. Glenn, Captain Virgil I. (Gus) Grissom, Lieutenant Commander Walter M. Schirra, Lieutenant Commander Alan Shepard, and Captain Donald K. (Deke) Slayton.
The footage shows the selection criteria and process, the astronauts in training, and the beginnings of our knowledge of manned space flight.
Project Mercury was the first human spaceflight program of the United States led by its newly created space agency NASA. It ran from 1959 through 1963 with the goal of putting a human in orbit around the Earth, and doing it before the Soviet Union, as part of the early space race. It involved seven astronauts flying a total of six solo trips.
On May 5, 1961, Alan Shepard became the first American in space in a suborbital flight after the Soviet Union had put Yuri Gagarin into orbit one month earlier. John Glenn became the first American to reach orbit on February 20, 1962. He was the third person to do so, after Soviet Gherman Titov made a day-long flight in August 1961.

“Today, the first American to orbit the Earth, NASA astronaut and Ohio Senator John Glenn, passed away. We mourn this tremendous loss for our nation and the world. As one of NASA’s original Mercury 7 astronauts, Glenn’s riveting flight aboard Friendship 7 on Feb. 20, 1962, united our nation, launched America to the forefront of the space race, and secured for him a unique place in the annals of history.
“While that first orbit was the experience of a lifetime, Glenn, who also had flown combat missions in both World War II and the Korean War as a Marine aviator, continued to serve his country as a four-term Senator from Ohio, as a trusted statesman, and an educator. In 1998, at the age of 77, he became the oldest human to venture into space as a crew member on the Discovery space shuttle — once again advancing our understanding of living and working in space.
“He earned many honors for both his military and public service achievements. In 2012, President Obama awarded him the Presidential Medal of Freedom, the highest civilian honor the country can bestow, and he also received the Congressional Gold Medal.
“Glenn’s extraordinary courage, intellect, patriotism and humanity were the hallmarks of a life of greatness. His missions have helped make possible everything our space program has since achieved and the human missions to an asteroid and Mars that we are striving toward now.
“With all his accomplishments, he was always focused on the young people of today, who would soon lead the world. ‘The most important thing we can do is inspire young minds and advance the kind of science, math and technology education that will help youngsters take us to the next phase of space travel,’ he said. ‘To me, there is no greater calling … If I can inspire young people to dedicate themselves to the good of mankind, I’ve accomplished something.’ Read the rest of this entry »
The multiple-axis space test inertia facility, fondly called “the gimbal rig,” simulated tumble-type maneuvers that might be encountered in space flight. From February 15 through March 4, 1960, the gimbal rig provided valuable training for all seven Project Mercury astronauts. John Glenn explains how it worked and what the experience was like.

On February 20, 1962, NASA astronaut John Glenn became the first American to orbit the Earth in his Mercury capsule Friendship 7. In 4 hours and 56 minutes, John Glenn circled the globe three times, reaching speeds of more than 17,000 miles per hour. The successful mission concluded with a splashdown and recovery in the Atlantic Ocean, 800 miles southeast of Bermuda.
In this video, Glenn discusses the Multiple Axis Space Test Inertia Facility, informally known as the “gimbal rig,” used to train the “Original Seven” Mercury astronauts for America’s first human spaceflights.
The rig, which simulated an out of control spacecraft and required the astronauts to bring it back under control, was located at what was then NASA’s Lewis Research Center near Cleveland, Ohio. That center now bears Glenn’s name. Read the rest of this entry »
One of the original “Magnificent Seven” astronauts in NASA’s Mercury program, John Glenn captured the nation’s attention in 1962 when he first circumnavigated the globe and returned as a hero who had scaled heights no American had reached before. In his post-NASA career, Glenn served four terms as a U.S. senator from Ohio. Following his […]

Quin Hillyer writes: As Donald Trump builds his Cabinet, too little public attention has focused on the quasi-Cabinet-level position of Administrator of the National Aeronautics and Space Administration (NASA).
It’s an agency needing significant attention – and in Trump-supporting Alabama, home to Huntsville‘s Marshall Space Flight Center, we should be pushing for NASA to be revamped, re-energized, and perhaps re-imagined.
NASA traditionally has been one federal agency that gets good “bang for the buck,” in terms of benefits to human life. Because of experiments that can be conducted only in the weightlessness of space, NASA has contributed mightily to human medicine in ways too numerous to count (heart-transplant-related devices, artificial limbs, and pain reduction during cancer treatments among them). NASA also has contributed in many ways to highway safety, mapping, weather tracking (especially valuable for those of us who deal with hurricanes), oil-spill cleanup, and better computer software, not to mention the plethora of ordinary (non-life-saving) consumer products made possible or made better by NASA discoveries.
Meanwhile, NASA can boast a string of successes in its highest-profile role, that of exploration of both near- and deep-space. Sometimes we take for granted the astonishing feats of technology that NASA has produced – but recent robotic and orbiting analyses of Mars, and our amazing studies of distant semi-planet Pluto after a nine-year space flight, have added immeasurably to our knowledge of the solar system and its capacity for life. The orbiting Hubble Telescope, meanwhile, has opened new vistas into far-off galaxies we never knew existed.
Knowledgeable observers, it is true, will say that no need exists for only government to do everything space-related. They are correct:
Commercial/private space projects show signal successes and great potential for more. Nonetheless, the sheer scale and cost of rocketry makes space the one frontier in which the national government can rationally engage in public/private partnerships of the sort usually more suited to state and local governments.
