Are you serious? They have 7 other test units plus all of the other items they have. This is like sending a complicated scientific experiment 100 millions miles and realizing there is a minor glitch based on information you learned after arrival.
No, like driving your car across the country by remote control and missing the slot in the return by 1/4" the first time you try. So you'll try again in a while.
Why are you and some of the other folks on here so negative about an amazing feat of technology? I wonder if Michelle Obama was ever proud of NASA.
