How many satellites have we put in orbit?
May 20, 2013
Good Day! A couple of days ago I gave a presentation to remember Yuri Gagarin's first manned Space Flight a the school of my kids. In the presentation for the 7 to 11 years old I received a lot of interesting questions (my toughest audience ever ;-) and one I'm not able to answer or know how to find a response. I found this: http://www.universetoday.com/42198/how-many-satellites-in-space/ and keep this one in My Favourite Links: http://www.planetary.org/blogs/emily-lakdawalla/2012/09281400-whats-up-october-2012.html But is there any good number? Rockets launched that the payload reached orbit? Satellites outside Earth orbit? Military versus Scientific versus Commercial? Manned versus unmanned? Thanks in advance Silvio Casagrande
