to all the naysayers ....
Yes, the original mission did not go as planned - hey we are talking an extremely hostile environment in space.
The mission in my estimation was a success - but of course there will be the obese lounge lizard with a drone who coulda' - woulda' - shoulda' done it better if he'd been asked.
This kind of mission was the stuff of dreams in my boyhood and I'm stoked that I've been alive to see it happen.
Cut the mission operators some slack and if you think you can do better/cheaper then give Kickstarter a try!
As my old Dad would have said - " Well done that man"
My 2c worth - keep the change naysayers.
