I think this shows the heights of what any man can do. This rather simple mission strikes me as one of the coolest things that I have ever seen. This picture is of Dale A. Gardner catching a satellite. He floated over to it in free flight, grabbed on and attached a control device to Westar 6 (the satellite seen here) before piloting it into the cargo hold of the space shuttle. Not much fanfare to it, but it's still amazing to think that this happened. If you want to read more about it, click here.
