A bus-sized asteroid buzzed Earth (with just days notice)

A bus-sized asteroid buzzed Earth (with just days notice)

Funding for asteroid detection and the need for greater awareness of potentially dangerous space rocks has been sparked again, after astronomers caught sight of a bus-sized asteroid headed closer to Earth than the moon's orbit only days before it passed. 2014 HL129 came within 186,000 miles of us in the early hours of Saturday morning, NASA's Asteroid Watch project confirmed, having only spotted the roughly 25 foot wide rock the previous Wednesday.

A Zombie war is raging in the deep sea

A Zombie war is raging in the deep sea

As we prepare for the likely Zombie apocalypse, signs begin to emerge that it’s a more widespread issue than previously imagined. Deep sea bacteria have been found infected, feeding tirelessly on the sweet, sweet sulfur that spews from vents on the ocean floor. Though they normally feed on them as a means of survival, a virus is causing them to mindlessly  accelerate their feeding.

NASA launches Space Station lifeboat project

NASA launches Space Station lifeboat project

If Sandra Bullock in Gravity proved anything, it's that George Clooney is smug even in space and that having an emergency exit back to Earth is probably a good thing. NASA is now working on the latter, with plans to equip the International Space Station (ISS) with a dedicated lifeboat for the first time in forty years, giving the orbiting crew there a place to not only shelter from incidents on the platform, but a way to escape it should something go seriously wrong.

SpaceX reusable F9R rocket aces 1,000m safe landing trial

SpaceX reusable F9R rocket aces 1,000m safe landing trial

SpaceX has shared new footage of its Falcon 9 Reusable (F9R) rocket being tested only for the second time, carefully blasting up to 1,000m and then safely returning back to the ground. The rocket quadrupled the height that it reached before descending over the first trial, making a landing that was a whole lot more successful than that of the SpaceX Falcon 9 last week.

How to build an Egyptian pyramid? Just add water

How to build an Egyptian pyramid? Just add water

One of the enduring mysteries of the pyramids - how ancient Egyptians managed to transport the huge stones used in their construction - may have been solved, with researchers discovering that simply adding water might have been enough. Blocks were known to have been dragged on sleds, but historians had always been uncertain as to how the Egyptian's workers avoided simply creating vast ridges of sand as the weight of the stones dug in.

Curiosity Rover set to drill into Windjana sandstone on Mars

Curiosity Rover set to drill into Windjana sandstone on Mars

NASA has been drilling into the surface of Mars using tools on the Curiously Rover for a long time now. The goal is to determine the composition of rocks on the planet and to help determine if any water exists or existed on the planet while ultimately looking for signs of life on the red planet. So far, Curiosity has drilled into two other rocks and both of them have been mudstone.
