[Explanation] Why send photographs from Mars on unknown, definition?

[Explanation] Why send photographs from Mars on unknown, definition?
August 6 past Curiosity ship landed successfully on the surface of Mars and began to conduct research, analyze the planet. In black and white images capture and Curiosity first ship sent to Earth, their quality is low and clear. NASA is not your camera has no ability to capture high quality images that a number of factors have affected the ability to capture images of Curiosity. After the first day, images will be sent to Earth much more clarity and explanation below.   Immediately below is the first color that ships sent to Earth Curiosity was taken from a device called MAHLI (Mars Hand Lens Imager). The yellow sand frames we can only see the dim distant mountains, MAHLI function is to a close (close-up) of rocks and gravel on Mars only. MAHLI have image sensor 1.9MP resolution equivalent and so it is enough to capture a close-up as normal but clear, protective coating made worse picture ever.   Shell protects the camera     All 12 cameras mounted around the Curiosity will be fitted with a transparent protective cover to protect the lens from a substantial impact in the process of landing on the surface of Mars. When approaching the surface near Mars, the rocket will be activated to help Curiosity landed safely and it creates a lot of dust, can scratch the lens, so the crust will also help protect against scratches to the lens of the camera.   Transparent protective cover is mounted on the camera will be removed in the coming days when dust no longer affect the surface of the camera lens. NASA engineers decided to use throughout the crust because they fear mechanism to remove the crust will get an error and can not take pictures. Then take the picture but it's better dim or will not shoot better?   The camera detects dangerous     True to its name, this camera is attached to the front of Curiosity early detection of threats from the ground to the ship. As a camera detects dangerous, so do not expect the beautiful photos taken from this angle. Like the other cameras, the machine has an extra protective cover over the camera but it is first remove the protective layer after the grounding. The black and white picture above was taken from a camera to detect danger before and after left the protective cover.   In order to detect a risk most effectively, NASA engineers used a fisheye lens of ultra-wide angle shooting and features 3D 1MP camera resolution. Because the use of fisheye ultra wide angle that camera images taken from blurred and distorted image in the corner, the engineers had to edit the image to minimize distortion and blurring of the image.   Original image is often very little   After landing on Mars Curiosity and it starts sending the first photographs of the earth but the image is quite small, in thumbnail form only. The camera detects dangerous photographed then reduce the size of the image down to just 64 x 64 pixels and send them as quickly as possible. Similar to the first video (below) when preparing the ship landed in Mars, the camera captured 297 MARDI thumbnail shape and assembled into a video and sent to the control center. Standard resolution of 1600 x 1200 MARDI is but the current pixel, we can not watch this in high resolution.     12 cameras on Curiosity     Picture above illustrates the location of a total of 12 cameras mounted around the body of Curiosity with different tasks, some capable of 3D imaging. The camera includes two lenses positioned to capture black and white 3D is mounted on top of Curiosity navigation tasks. In addition, Curiosity also has a duty camera with laser component analysis of Martian rocks. MastCam duty color pictures, panorama or video (at a speed of 10 frames / sec) at high resolution. MastCam left to 100mm focal lengths to record images at greater distances.   Curiosity process amphibious ships    Galleria.loadTheme ('/ js / Tinhte / Galleria / themes / azur / galleria.azur.min.js'); $ ("# Galleria_721335528").
