"It's a very strong design,"
It most definitely is. Time and time again we see our spacecraft outlive their mission plan due not only to well-designed craft, but mostly to the intelligence, ingenuity and dogged determination of the people who are in charge of operating them. This is a testament to the dedication humans are capable of in attaining the goal and going beyond. It is a marvelous asset for our future, and always make for very interesting reading.
Well done boffins, again !
