NASA ISS spacewalk a success: computer death fixed

NASA ISS spacewalk a success: computer death fixed

A relatively short spacewalk outside the International Space Station earlier today resulted in NASA astronauts repairing a dead computer. This particular computer system was critical to future missions, and the mission took less than an hour while original projections suggested it’d take between an hour and three hours.

New laser tech may give science the ability to control the weather

New laser tech may give science the ability to control the weather

A study has been published that outlines a method of creating a laser beam that can travel further than lasers were previously able to travel. Researchers from the University of Arizona have developed a way to increase the distance the laser can travel in air by encasing it in the beam of light of another laser. The process is described as being similar to wrapping a wire in an insulating layer.

B612 says Earth avoids massive asteroids with “blind luck”

B612 says Earth avoids massive asteroids with “blind luck”

With Earth Day round the bend, you’d expect to hear some positive news regarding our planet and the celestial bodies that surround it; instead we have some not-so-good-news. According to former NASA astronauts, we're depending on "blind luck" when it comes to the asteroids avoiding our planet. Apparently we get hit three to ten times more by large-scale asteroids than what is being officially declared by the authorities, this information being brought forward by this trio of space-fairing fellows this week.

Raindrops and toilets can potentially power your home

Raindrops and toilets can potentially power your home

Scientist from South Korea have a found a way to harness power from a flushing toilet to generate electricity. Technically the application can be extended from toilet flushes to rainwater, ocean waves, river currents, even to a drop of water. However, it sounds way cooler when we say that the mechanical energy from flowing water in your toilet bowl can potentially power your home.

SpaceX CRS-3 Falcon 9 launches for ISS resupply mission

SpaceX has successfully launched its CRS-3 Mission, the second attempt to send the Falcon 9 rocket and Dragon spacecraft to the International Space Station and further demonstrate the effectiveness of its reusable technology. The launch - scratched earlier in the week - will take a number of specialist devices and equipment to the ISS, including a new laser communication array, and high-resolution cameras which will give viewers new glimpse of Earth from orbit.
