How many satellites have we put in orbit?

Silvio Casagrande

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: and keep this one in My Favourite Links: 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
