Fantastic achievement. Seven minutes to go from 20,000kph to 0. I think the thing that boggles my mind is that when NASA heard the signal from the capsule that it was starting it's landing sequence, it had already been on the ground for 7 minutes - Mars is that far away.
By the way... it's more INTERNATIONAL COOPERATION-INTERNATIONAL COOPERATION-INTERNATIONAL COOPERATION
NASA had the help of several, if not many countries, who provided key knowledge and key technologies. NASA could not have done this without their help. I would bet money that in the photo uploaded, at least one of those engineers is not American. It is a (nearly) unique trait that American media will assign all credit to "America" on these multinational projects.
NASA has earned and deserves recognition for pulling this project together. I don't think any one else could have coordinated and funded a project of this size. But let us also give credit to the numerous other nations who were asked by NASA to provide the key technologies and knowledge that NASA needed to pull this off.
