Cosmic rays could leave travelers to Mars confused, forgetful and slow to react
“These sorts of cognitive changes could manifest during the mission and could be a real problem.”
In a NASA-funded study of radiation-exposed mice published Friday in Science Advances, researchers at the University of California, Irvine and the University of Nevada warned that prolonged bombardment by charged particles in deep space could affect the brain cells involved in decision-making and memory, with implications for possible manned forays into deep space.
“I don’t think our findings preclude future space missions. But they suggest we need to come up with some engineering solutions.”
— UC Irvine radiation oncologist Charles Limoli
“These sorts of cognitive changes could manifest during the mission and could be a real problem,” said Cary Zeitlin at the Southwest Research Institute in San Antonio, who wasn’t involved in the study. In 2013, Dr. Zeitlin reported radiation levels between Earth and Mars detected by the Mars Science Laboratory craft during its cruise to the red planet, and found that the exposure was the equivalent of getting “a whole-body CT scan once every 5 or 6 days.”
“Apollo crews, who ventured furthest from Earth’s protective shield on their journeys to the Moon, reported seeing flashes of light when they closed their eyes, caused by galactic cosmic rays speeding through their retinas.”
Deep-space radiation is a unique mix of gamma rays, high-energy protons and cosmic rays from newborn black holes, and radiation from exploding stars. Earth’s bulk, atmosphere and magnetic field blocks or deflects most deep-space cosmic rays. Shielding on spacecraft also helps. Read the rest of this entry »
Today in History: 1598 Birthday of Bernini, Whose Breathtaking Reimaginings of classical Myth, Including Apollo & DaphnePosted: December 7, 2014

At 7:05 a.m. Eastern time on Thursday, December 4, an unmanned, unpressurized version of NASA’s Orion crew capsule will lift off from Cape Canaveral for its first test flight, called Exploration Flight Test-1. This will mark the debut of the first new NASA spacecraft meant to fly astronauts since the Space Shuttle took flight in the early 1980s. And while this first flight will be unmanned, it will see a crew capsule travel farther from the planet’s surface than any manned vehicle design has gone since the Apollo moon mission…(read more)
“When Apollo 11 landed on the moon 45 years ago, this space station that we live on was science fiction”
International Space Station astronauts Steve Swanson and Reid Wiseman salute the Apollo 11 mission on the 45th anniversary of its launch.
“But today it is reality thanks to the legacy of the Apollo astronauts…”
“When Apollo 11 landed on the moon 45 years ago,” says Swanson, “this space station that we live on was science fiction. But today it is reality thanks to the legacy of the Apollo astronauts and all the nations that have followed the path to space since then.”
A good deal from Famous Monsters of Filmland. This is actually true, though they weren’t astronaut helmets or suits, they were designed for wear in the U2 spy plane and the NACA supersonic test flights.
WASHINGTON — Some of the most iconic artifacts of aviation and space history will be getting an updated display for the 21st century, with the Apollo moon landing as the centerpiece.
“We’re trying to figure out what the museum needs to do to stay in touch. We want to inspire people of all ages to want to know more and to do more.”
— Museum Director J.R. “Jack” Dailey
For the first time since its 1976 opening, the Smithsonian’s National Air and Space Museum plans to overhaul its central exhibition showing the milestones of flight. The extensive renovation announced Thursday will be carried out over the next two years with portions of the exhibit closing temporarily over time, said Museum Director J.R. “Jack” Dailey.
Charles Lindbergh’s “Spirit of St. Louis” aircraft from the first trans-Atlantic flight, John Glenn’s Mercury capsule from his first Earth orbit and an Apollo Lunar Module recalling America’s first moon landing will be among the key pieces to be featured. Such artifacts have made the Air and Space Museum the nation’s most-visited museum, drawing 7 million to 8 million visitors each year.

True beauty pleases the eye and the mind – but can it help us to become better people?
John Armstrong writes: The only popular thought about beauty today, the one that has the widest currency in the world, is the idea that beauty lies in the eye of the beholder. It’s a kindly notion. It seeks to make peace between people who have very different tastes. People are delighted by wildly variant things and that’s how it should be, the thinking goes – so don’t get worked up trying to figure out which things are beautiful.
Yet the success of this generous approach keeps attention away from deeper, more important questions. Whether it is a Baroque Cathedral, the face of a child, or the coast of Sweden seen from a plane window, we have all had the mysterious experience of finding something beautiful. But what is actually going on when we find these things beautiful?
[On the Aesthetic Education of Man in a Series of Letters (English and German Edition) at Amazon]
In 1795, the German dramatist and poet Friedrich Schiller published a book with a fearsome title – On the Aesthetic Education of Man in a Series of Letters. It has never become well-known, which is a pity, because it contains some of our most useful insights into the nature and value of beauty. Schiller’s starting point is an analysis of the human condition. He wants to understand our delight in what we find beautiful. Instead of asking which things are beautiful, Schiller is curious about what is going on in us when we respond with this distinctive, intimate thrill and enthusiasm that leads us to say ‘that’s beautiful’. Different things might provoke this response in different people. But why do we have it at all?
In total, the Apollo program resulted in 12 spaceflights and 12 astronauts who walked on the moon. The program developed as a result of President John F. Kennedy challenging the nation, in 1961, to land on the moon by the end on the decade.
