Could the 14-minute waiting time be compared to the anticipation that the Cape Canaveral control room experienced waiting for the Apollo missions to the moon back in the 1960s? Seems then there was also a waiting period before confirmation that the Eagle had landed. Maybe this is much more hazardous, and good that it is unmanned.http://www.youtube.com/watch?v=6R3j1NU2nQM

Comms delays for Apollo was more like 2 seconds, and there was constant telemetry flowing back to Houston mission control during lunar descent. Indeed, the LM crews were always being told to realign their antennas so Houston could continue receiving systems telemetry and voice. The difference of course was that there were two humans aboard. We're a long way from a manned Martian landing.

That is a lot of unproven technologies to try all on the same mission. The reasoning is logical, but the end result could be a catastrophic waste of time and money. I'd be interested to hear what JPL's engineers calculated was the probability of success.

I love the fact that at 0:23, "Code" is spelled incorrectly (Cod3). Im really hoping that was a joke, otherwise my faith in them getting all 500,000 lines correct just took a bit of a nosedive...

Let's hope they dont mix-up English and Metric units again..... Seriously, though, I'm curious how much testing was (or could be) done here on Earth given Martian gravity is 38% of Earth's.

Is it irony or subtle humor that the graphic at about 0:21 says "500,000 LINES OF [sic] COD3", followed by "ZERO MARGIN OF ERROR"? Just hoping we're not back to the era of the km/miles debacle and sensors on spring-loaded legs without debouncing.

The delay was when they went behind the moon and were out of communication for many minutes. Not radio wave propagation delay.

"...Gale Crater, which is suspected of harboring signs of Martian life." Signs of water, yes. Conditions suitable for life, yes. Signs of life, ummm, no.

You seem to have missed that it also said "L1nes" instead of "Lines". Obviously intentional Leet-speak, or 1337 if you will.
