Since the 9/11 attacks, no book has provided a satisfactory answer as to WHY the attacks occurred and who was ultimately responsible for carrying them out - until now.
While @Philae2014 takes time out to rest after #CometLanding I've still got a lot of this to do at #67P: http://t.co/CV9Ysfow32The European Space Agency (ESA) team found that the surface of the comet is "hard as ice," which made it difficult for the lander to dig into the surface especially after a harsh landing. The drilling has been dubbed a 'tough nut to crack'.

It happens all the time: small asteroids impact Earth's atmosphereBy not providing a year-on-year breakdown of the impacts, and by including their rather banal headline, NASA leaves us to assume that these events were more or less evenly distributed over those 20 years - on average, 27 fireball events of note in 2013 (556 total events/20 years). But we have serious doubts about this.
