NASA discovers hundreds of pits on the surface of the moon.
While the moon's surface is battered by millions of craters, it also has over 200 holes – steep-walled pits that in some cases might lead to caves that future astronauts could explore and use for shelter, according to new observations from NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft.

Astronaut Sally Ride and the Burden of Being The First.
'Tampons were packed with their strings connecting them, like a strip of sausages, so they wouldn’t float away. Engineers asked Ride, “Is 100 the right number?” She would be in space for a week. “That would not be the right number,” she told them. At every turn, her difference was made clear to her. When it was announced Ride had been named to a space flight mission, her shuttle commander, Bob Crippen, who became a lifelong friend and colleague, introduced her as “undoubtedly the prettiest member of the crew.” At another press event, a reporter asked Ride how she would react to a problem on the shuttle: “Do you weep?”'

In November of 2013, I found myself the lone bidder of a Russian high altitude space suit on an auction website called RRauction. Since then, I’d been scheming how to best use the suit. I have been revisiting my childhood love for space and my obsession was growing stronger and stronger. It was only natural to use this suit to project the inner child in me, still dreaming about space. With that, I present to you: "A day in the life of Everyday Astronaut".

“The cancellation of the space shuttle may be the biggest blunder ever made by the United States,” Kraft said. “It’s fairly obvious that no one in the government thought through what they were about to bring about when they made that decision.”

Trip to Mars Doesn’t Have to Break the Bank
Just days after the launch of India’s Mangalyaan satellite, NASA sent off its own Mars mission, five years in the making, named Maven. Its cost: $671 million. The budget of India’s Mars mission, by contrast, was just three-quarters of the $100 million that Hollywood spent on last year’s space-based hit, “Gravity.”
“The mission is a triumph of low-cost Indian engineering,” said Roddam Narasimha, an aerospace scientist and a professor at Bangalore’s Jawaharlal Nehru Center for Advanced Scientific Research.
“By excelling in getting so much out of so little, we are establishing ourselves as the most cost-effective center globewide for a variety of advanced technologies,” said Mr. Narasimha.

In 1972, Tom Wolfe was assigned to do a piece for Rolling Stone on Apollo 17, NASA's last moon mission
(Google book preview). That turned into a four-part series on the astronauts, written in a frantic three weeks. From there, he thought he could quickly expand the piece into a book
(Gbp). But that book, on what makes an astronaut, ended up taking a much broader scope and more time. In 1979, The Right Stuff
was published, and later was made into a well-regarded 3 hour movie
. A few years later, Andrew Chaikin started on a similar path to Wolfe, more broadly documenting the US moon missions in his book, A Man on the Moon

About this time, it came to my mind that during one of our training sessions we were told that one of the fully fueled prototype S11 rocket stages had been exploded out in the desert.

of this 363ft tall bomb that sounded like it's giant fuse had been lit, and we were soon going to get much closer.
