Someone, somewhere, turned on a subwoofer.<\/p>\n

My wife and I looked at each other and we both said \u00e2\u20ac\u0153WOW\u00e2\u20ac\u009d.<\/p>\n

All windows in our house were rattling. Not just a little in the direction of the noise, but ALL windows around the house were vibrating at a low frequency.<\/p>\n

It was 4:38 AM!<\/p>\n

And the subwoofer was located some 40+ miles away from us.<\/p>\n

That is, when it was turned on.<\/p>\n

By the time our windows started to tremble, the subwoofer was already some 10 miles up in the air: one of the last Delta 2 rockets, blasted into orbit with the help of NINE solid rocket boosters, 6 of which were ignited on the ground, the other 3 during the ascent.<\/p>\n

We were watching its launch form our backyard, and it was a true spectacle. We could clearly see the ignition of the 3 remaining boosters and the jettison of the burned-out ones.<\/p>\n

Anyway, we now have a brand new GPS satellite in orbit. And it will also test the new L5 signaling for future, more accurate and more powerful GPS with extra provisions for aviation.<\/p>\n

The Delta 2\u00e2\u20ac\u2122s are being phased out and replaced by Delta 4 and Atlas 5 rockets.<\/p>\n

Interested in one of the oldies? The Air Force has 5 of them for sale!<\/p>\n
