First Preserverence Image from mars

This is what happens when your robot on the surface of mars takes its first snapshot and forgets to remove its lens cap.
Been there, done that.
Been there, done that.

Ha! They said that was the low res navigation camera. I guess the real pics take a long time to get here. A very long camera connect cable had to be paid out.

Wow, if I forget to remove the lens cap on my cameras all I see is black.

They said that the cover had to be left on until the dust kicked up by the landing settled out. I think it's an amazing accomplishment.

And, there is a color checker on the top deck of the rover

Monday we will have hi-resolution photos. This photo was taken thru a thin plastic dust cover. Interesting to see if the helicopter flies... Quite a long way from the bouncing ball landing a decade ago.. wow for the sky crane

Yeah, I was wondering about that too. With a very thin atmosphere that drone must have some huge blades. Over-all an incredible accomplishment!!

Not so much on the blade size, there are two that counter-rotate and they must spin very fast.
And the entire helicopter only weighs four pounds, a pound lighter than a Great Blue Heron!

The Soviets had numerous problems with the lens caps on their Venera spacecraft that landed on Venus. On many of the missions, the titanium lens cap would not come off, the heat and pressure on Venus was greater than the anticipated environmental parameters. Their later spacecraft had dual cameras and one of the lens caps would come off giving what few pictures we have of the surface of Venus. On one of the later flights, there was an experiment to determine the compressibility of the Venusian soil by having a hammer with a spike on a long arm swing down and hit the ground. By measuring how the arm slowed down and its penetration, Soviet scientists could determine the soil properties. Unfortunately, what works fine in a lab on Earth doesn't ensure it will work at Venusian heat and pressure. The lens cap did not pop off properly and landed where the hammer spike would hit the soil. When the arm was released, it hit the titanium lens cap which stopped the hammer from penetrating the soil.

lens caps are kept on as stated before due to dust kicked up by landing. did you see the image from the sky crane as it dropped the rover? amazing
