- JPL mission controllers break out jars of peanuts shortly before the landing. It’s a tradition before critical mission events that started with the first successful Ranger mission to the moon in the 1960s. A JPL staffer was eating peanuts at the time, so the staff figured the peanuts brought good luck. Credit: NASA-TV

It was far more impressive because it was not pre-programmed at all. The probe was autonomous, but not simply following a script. It needed to adjust its course and attitude, compensate for variations in atmospheric density, and find a flat spot to land- all on its own.
<<Autonomy (Ancient Greek: αὐτονομία autonomia from αὐτόνομος autonomos from αὐτο- auto- "self" + νόμος nomos, "law", hence when combined understood to mean "one who gives oneself their own law") is a concept found in moral, political, and bioethical philosophy. Within these contexts, it is the capacity of a rational individual to make an informed, un-coerced decision.
Autonomy is not to be confused with Autotomy. Autotomy (from the Greek auto = "self-" and tomy = "severing") or self amputation is the act whereby an animal severs one or more of its own appendages, usually as a self-defense mechanism designed to elude a predator's grasp.
In moral and political philosophy, autonomy is often used as the basis for determining moral responsibility for one's actions. One of the best known philosophical theories of autonomy was developed by Kant. In medicine, respect for the autonomy of patients is an important goal of deontology, though it can conflict with a competing ethical principle, namely beneficence. Autonomy is also used to refer to the self-government of the people.
An Autonomous Space Craft might make certain decisions for itself based on imagery observation and a pre-programmed algorithm that will determine the only possible logical outcome and then perform that task without having to ask controllers NAND NOR AND types of parameters. Autonomy in Space does not relate to the socio-political definitions, here we are talking about a device that can make basic or convoluted decisions based on LOGIC (in an electronic usage).
To have true Autonomy however a device (or entity) would need to have a longer leash being able to complete complex missions without human intra direction. Such a system would say further automate the other elements of the total process making the whole of the "system" larger by including more devices that multicommunicate with each other without involving ground based technicians or communications. (the military might not want to send possibly interceptable signals to and from said same).>>

Pretty much every action that occurred during the descent and landing phase required analysis, calculation, and decision making on the part of the probe.
A very slick operation, and a testament to superb engineering.
The parachute appears fully inflated and performing perfectly. Details in the parachute, such as the band gap at the edges and the central hole, are clearly seen. The cords connecting the parachute to the back shell cannot be seen, although they were seen in the image of NASA's Phoenix lander descending, perhaps due to the difference in lighting angles. The bright spot on the back shell containing Curiosity might be a specular reflection off of a shiny area. Curiosity was released from the back shell sometime after this image was acquired.
This view is one product from an observation made by HiRISE targeted to the expected location of Curiosity about one minute prior to landing. It was captured in HiRISE CCD RED1, near the eastern edge of the swath width (there is a RED0 at the very edge). This means that the rover was a bit further east or downrange than predicted.
The image scale is 13.2 inches (33.6 centimeters) per pixel.

Just a quick update: new analysis of the incredible picture from the HiRISE camera on the Mars Reconnaissance Orbiter showing Curiosity parachuting to the surface of Mars has revealed a new detail: the rover’s heat shield:
Very cool! But it gets better: given when this shot was taken, and the lack of disturbed dust under the shield, it’s thought that this shows the heat shield still falling to the surface! It’s an action shot! The heat shield was the blunt end of the spacecraft that protected the rover from the heat of atmospheric entry, and was ejected about a minute and a half before landing. It would’ve hit the surface seconds after this shot was taken.
As I write this (23:30 UTC) I’m watching the press conference, and they’re showing video of the descent as seen by the rover itself, and it’s amazing! I’m sure this will be available soon, and when it is I’ll post it. [UPDATE (August 7, 00:15 UTC): The video has been released, and here's my post about it!
