BOOM! NASA CAPTURES MASSIVE MOON EXPLOSION ON VIDEO

This NASA artist concept shows what the impact may have looked like.

It's a good thing you weren't standing on the moon's Mare Imbrium crater on March 17. You might have been ground into space dust. A meteoroid "the size of a small boulder" crashed into the lunar surface and exploded with a flash so bright, it was visible to the naked eye from Earth.

NASA has been keeping an eye on the moon for eight years, looking for explosions caused by meteoroids. The space agency has seen hundreds of detectable impacts, but none quite so spectacular as this one. "For about one second, the impact site was glowing like a fourth magnitude star," NASA says...

NASA accidentally improves weather forecasting with lunar dust-measuring lasers

Anyone that's ever tried to plan an outdoor activity in advance knows that weather forecasting is not an exact science, but the perpetual sky-watchers at NASA may have inadvertently found a way to improve these guesstimations. They have been testing a laser system for measuring lunar dust and soil kicked up by rocket exhausts, and while using precipitation as a substitute to calibrate the laser, they found they could measure the average size of raindrops passing through it. This value is estimated in current forecasting models, so plugging in some accurate numbers should make those predictions more reliable.

The original mission hasn't been forgotten, though. Particles whipped up by landing rockets on the moon's surface could damage what was left behind by the Apollo missions, ruining its scientific and historic value. One of the laser sensors may find its way onto a craft vying for Google's X Prize, with the results used to determine where vessels can touch down whilst keeping a safe distance from Apollo landing sites. Although an accidental discovery, the system's other potential career in weather forecasting will also continue to be explored. Now, if only there was a way to make it rain and speed up the testing.

NASA releases web app to help you spot ISS, celebrates 12 years of continuous crew occupation

The International Space Station just celebrated its 12th anniversary of having a crew continuously onboard, and to mark the occasion, NASA's unveiled a new service to help folks catch the station in the night sky. Dubbed Spot the Station, the web app texts or emails the time that the ISS will pass over a user's location to their phone. The calculations are done for more than 4,600 places across the globe by NASA's Johnson Space Center, which determines when the ISS will be high enough in the sky to be seen above obstacles such as trees and buildings. Since the station is the second brightest object in the night sky after the moon, it'll appear to the naked eye as if it were a star moving at a steady clip. To get pinged with sighting alerts by NASA, hit the second source link below.
