The Curiosity rover, which is designed to explore Mars, has found an ancient oasis on Mars. Researchers working with the Curiosity rover have found salt-enriched…
Scientists were able to collect the largest digital camera ever built for a space mission. The camera consists of 106 individual electronic sensors. The resulting “one billion pixels,” will serve as a super-sensitive “eye” for the mission Gaia ESA, which aims to create a three-dimensional map of the Milky Way.Gaia will map a billion stars within our own Galaxy during its five-year mission, which will begin in 2013.To detect distant stars Gaia will help the system of 106 devices (CCD), the advanced versions of the chips in standard digital cameras. These rectangular sensors are a little smaller than a credit card (each 4,7 × 6 cm), but thinner than a human hair. The finished mosaic laid in seven series CCD.
The main set consists of 102 sensors designed to detect the stars. Four other check image quality of each telescope and stability of angle 106.5 º between the two telescopes, which uses Gaia, to obtain stereo images of the stars. To increase the sensitivity of their sensors, the spacecraft will maintain their temperature at around 110 º C.Structure to support CCD, like most of the rest of the spacecraft, made of silicon carbide.
