On earth, nuclear reactors are under attack because of concerns over damage caused by natural disasters. In space, however, nuclear technology may get a new lease on life. Plans for the first nuclear power plant for the production of electricity for manned or unmanned bases on the Moon, Mars and other planets were unveiled today at the 242nd National Meeting & Exposition of the American Chemical Society (ACS). James E. Werner, the project leader at the U.S. Department of Energy (DOE), said that innovative fission technology for surface power applications is far different from the familiar terrestrial nuclear power stations, which sprawl over huge tracts of land and have cooling towers and other large structures.

And there are no cooling … [Read more...] about Nuclear power plants for settlements on the Moon and Mars

Video: How to be safe while viewing the 2017 solar eclipsePeople have long been fascinated with solar eclipses, with popular folklore ranging from Viking sky wolves to Korean fire dogs to explain why the sun suddenly disappears during the middle of the day. On August 21, a total solar eclipse will be seen across a 70-mile swatch of the US, and it's fueling an eclipse-viewing mania since it will be the first total solar eclipse to travel from the Pacific Ocean to the Atlantic Ocean since 1918. And it's the first time a total solar eclipse has occurred exclusively in the US since 1778.SEE: Two NASA jets will chase the solar eclipse for never-before-seen images and massive data collection (TechRepublic)Every single state in the US will experience at least a partial eclipse on August 21. But for some states such as Hawaii--where only about 18% of the sun will be blocked by the moon--it won't be nearly as noticeable as in the 14 states in the continental US that will experience a total … [Read more...] about Watch the solar eclipse of the century: When, where, and how
Say you have two objects: a billiard ball and a feather. You drop both from the same height at the same time. You lay odds on the ball hitting the ground first -- and you're probably right, even if it's just by a split-second. However, as demonstrated by Galileo in 1589, mass does not affect gravitational pull; theoretically, all things should fall at the same rate, regardless of how heavy they are.Back in 1971, on his last day on the moon, Apollo 15 Commander David Scott tested this theory. In one hand, he took a 1.32kg aluminium geological hammer. In his other, a 30g falcon feather, 44 times lighter than the hammer. Sure enough, when he dropped them both from the same height at the same time, they hit the ground simultaneously -- thus demonstrating Galileo's theory.On Earth, it doesn't necessarily work this way. This is because the planet is enclosed in a bubble of gas -- the atmosphere -- which causes an effect called aerodynamic drag, particularly on objects that have a … [Read more...] about What happens when you drop a feather and a hammer on the moon?
TOKYO -- The race to the moon is more marathon than sprint, but for some entrants to the Google Lunar XPrize, the finish line is finally coming over the horizon. The contest represents a $30 million pool of prizes, funded by Google and managed by the XPrize Foundation. A whopping $20 million goes to the first privately funded team to put a lander on the moon and cover a distance of 500 meters, all while sending high-definition video back to Earth. There's a $5 million prize for second place, and $5 million in bonuses. The goal is to kick-start the commercial space industry, while also inspiring a new generation of engineers and scientists.Sixteen competitors remain, and last year we profiled a number of them as they quested for an additional set of so-called milestone prizes. This $6 million cash infusion was designed to keep the teams going through the incredibly expensive process of testing their hardware and, ultimately, securing a one-way ticket to space.When a berth on something … [Read more...] about Google Lunar XPrize update: Five teams aim for the moon in 2017
I'm not sure what mental image you had when visualizing what Charon, Pluto's largest moon, looked like, but it probably wasn't an imploding Death Star with a huge friggin' welt on its head. But that's exactly what NASA's New Horizons probe found spinning around everyone's favorite once-upon-a-planet. The latest high-res photo was taken just before New Horizon's closest approach to the Plutonian system back in mid-July. Charon is only 754 miles across (for a point of comparison, that's roughly the distance between New York City and Charleston, South Carolina) and the latest enhanced-color image shows a frozen world with near-boundless variety and beauty. "We thought the probability of seeing such interesting features on this satellite of a world at the far edge of our solar system was low," Ross Beyer, an affiliate of the New Horizons Geology, Geophysics and Imaging (GGI) team, wrote in a NASA blog post, "but I couldn't be more delighted with what we see."
