Probe count.

To date, what is the exact number of every single probe, satelite, and so on, launched from Earth? This includes Russia, Europe, and every body else too. <div class="Discussion_UserSignature"> </div>

http://celestrak.com/columns/v04n01/<br /><br />For most of us, our satellite-tracking interests extend to only a small handful of satellites. Whether it be the amateur radio or weather satellites, TVRO, or even the combined GPS/Glonass constellation, we're typically talking about tens of satellites. Even if we consider all of the operational satellites on orbit, we're still only talking about hundreds of satellites. But there are those among us whose duty it is to track the now 8,500 satellites in earth orbit—payloads, spent boosters, and other debris—on a daily basis. These are the men and women of the Space Control Center (SCC), buried deep within Cheyenne Mountain.<br /><br />An Online Satellite Catalog<br /><br />Having access to the current SATCAT can be a useful tool for those involved with satellite tracking. Whether it is used to find something specific such as the NORAD Catalog Number for a satellite in order to obtain the proper element set or just to perform some statistical analyses (e.g., number of payloads on orbit, percent of the catalog launched by the US), the results can be both helpful and enlightening. If I had more space, I could regale you with various space trivia showing trends within the SATCAT. Perhaps I'll save that for another day.<br /><br />There's a table called Boxscore......<br /><br /><br />Anything floating around in space is a satellite. <div class="Discussion_UserSignature"> <font size="1" color="#3366ff">www.siriuslookers.org</font> </div>

And now, the spatula lost from Discovery is a satellite as well. <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> <p><font color="#ff9900">----------------------------------</font></p><p><font color="#ff9900">My minds have many opinions</font></p> </div>

but is it a "probe" and exactly what is it probing?
