Depends on which time point you take for "launched". ;^) It was
launched a month and a half before I was born and I also outweighed it
at that point. Or was it launched seven and a half months after I was
conceived and it outweighed me by a vast amount at that point in time!

Like you I was not conceived during the Space Age but I was born during
it.
