My friend was more in a hurry than I was, but I couldn't always find the signs fast enough that told us what we were looking at.
That said, I know I've seen this before, on TV and in newspapers and magazines (and later the Internet), but I can't remember if this was a satellite or a deep space probe. From its look, it seems to be more of a probe than just another communications satellite. If anyone knows what this is, post a response below. Thanks in advance.
