The Galileo system of navigational satellites will be a European equivalent of the US GPS or Russian GLONASS navigation systems. Here's a brief notice from ESA: http://www.esa.int/Our_Activities/Navigation/Galileo/Launching_Galileo/Watch_the_launch_of_Galileo-13_14 Europe takes its next step in creating its own navigation satellite constellation on Tuesday 24 May, with the launch of the 13th and 14th Galileo satellites. The pair is scheduled to lift off at 08:48:43 GMT (05:48:43 local time, 10:48:43 CEST) on 24 May from Europe’s Spaceport in French Guiana atop a Soyuz launcher. The first three stages of the Soyuz rocket take the Galileo satellites and their Fregat upper stage into low orbit just short of nine minutes after liftoff. Then the reignitable Fregat, as much a spacecraft as a rocket stage, then takes over the task of hauling the satellites higher through a pair of burns. The satellites will be released in opposite directions by their dispenser once they reach their target 22 522 km-altitude orbit at 3 h 48 min after launch. Streaming begins at 08:28 GMT (10:28 CEST) on 24 May for the liftoff, then resumes at 12:23 GMT (14:23 CEST) to cover the satellites’ separation.
This is an 1880 English translation of the Sidereus Nuncius which Galileo published in 1610 describing his observations of the Moon, Jupiter and its moons and the Milky Way using a telescope. https://archive.org/details/siderealmessenge80gali There are more recent translations, which may be better and more scholarly. However, this one is FREE For an overview of the work and its context, see: https://en.wikipedia.org/wiki/Sidereus_Nuncius By the way, an original first edition will set you back at least US$ 662,500 - pretty cheap!
A new (old) 'frac added to my wee family of scopes. From an Astromedia kit of a slightly smaller copy of one of Galileo's refractors. Not had a chance to view the night sky yet, but get a 12x magnification, so should be able to see the moon in a little more detail. Field of view is small, but as one of the first kind of telescopes made this was cutting edge back in the day I guess! Hope for a chance tonight to observe something if the clouds permit!
