The California-based B612 Foundation has released a video displaying the distribution of 26 multi-kiloton asteroid impacts known to have struck the Earth since the year 2000. Many of the impacts – detected by a network of satellites operated by the Nuclear Test Ban Treaty Organization – exploded with a force greater than that of the city-leveling bomb dropped on Hiroshima, which had an explosive yield of 15 kilotons.  Read More

In space, no one can hear you hit the Moon at near-hypersonic speed. Today, NASA's Ames Research Center announced that the Lunar Atmosphere and Dust Environment Explorer (LADEE) made a controlled impact on the far side of the Moon some time between 9:30 and 10:30 pm PDT on Thursday, bringing to an end its mission to study the lunar atmosphere.  Read More

The Falcon 9 rocket lifted off after three previous launches were scrubbed (Photo: SpaceX)...

It took four tries, but SpaceX’s CRS-3 mission is on its way to the International Space Station (ISS). Today at 3:25:21PM, EDT, the unmanned Dragon cargo spacecraft lifted off atop a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida in rainy, overcast weather that NASA said only gave the launch a 40 percent chance of going ahead without delay. The successful launch is SpaceX’s third cargo mission to the ISS and its fourth visit to the station.  Read More

Images from NASA's Cassini spacecraft taken Apr. 15 hint at the formation of a new Saturnian moon. The icy object, believed to be only half a mile in diameter, recently formed in Saturn's outer rings and has been given the provisional name, Peggy.  Read More

The search for extraterrestrial life zeroed in a bit today as NASA announced that its unmanned Kepler Space Telescope detected the most Earth-like planet yet found beyond the Solar System. Named Kepler-186f, the new planet orbits a red dwarf star about 500 light years away from Earth in the constellation of Cygnus, is only 10 percent larger than our planet, and could have liquid water, which is essential for life as we know it.  Read More

ESA's Sentinel-1A satellite has returned its first images of Earth from space in its second week of achieving orbit. The satellite, having been launched on Apr. 3, has only recently undergone a complicated maneuver to extend its 10 m (32 ft) solar wings and 12 m (39 ft) radar imaging array.  Read More

Monday's SpaceX Dragon CRS-3 launch was scrubbed due to a helium leak

Unfortunately, it wasn't third time's a charm for the SpaceX CRS-3 mission to send an unmanned Dragon cargo ship to the International Space Station (ISS). In a statement today, SpaceX announced that the Monday launch of the Falcon 9 rocket has been rescheduled until April 18 because of a helium leak in the first stage. However, weather forecasts show conditions around Cape Canaveral deteriorating as the week progresses, so even that date is tentative.  Read More

The International Space Station (ISS) may be a remarkable piece of engineering, but it’s so drab that it needs a window box to brighten things up. That isn't possible in the vacuum of space, but NASA is doing the next best thing on Monday as it sends its Vegetable Production System (Veggie) to the space station aboard the SpaceX Dragon CRS-3 mission. However, this plant-growing chamber will be more than a horticultural experiment, it's also a bit more culinary as it lets astronauts put fresh salad on the menu.  Read More

Getting hit by a giant asteroid can ruin your whole day, so the first United States mission to visit an asteroid and return a sample presents a huge challenge. Lockheed Martin has announced that NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission has passed a comprehensive technical review, giving the green light for Lockheed to begin building the spacecraft in anticipation of a launch in 2016.  Read More

ESA has released compelling video footage displaying the ascent of its Sentinel 1A satellite as viewed from external cameras mounted on the Soyuz Fregat launch vehicle which carried it into orbit.  Read More
