William Robinson writes "After an 18-day journey, Chandrayaan-1, the moon mission of India, has entered Lunar orbit. The maneuver was described as crucial and critical by scientists, who pointed out that at least 30 per cent of similar moon missions had failed at this juncture, resulting in spacecraft lost to outer space. The lunar orbit insertion placed Chandrayaan-1 in an elliptical orbit with its nearest point 400 to 500 kilometers away from the moon, and the farthest, 7,500 kilometers. By November 15, the spacecraft is expected to be orbiting the moon at a distance of 100 kilometers and sending back data and images (the camera was tested with shots looking back at Earth). The Chandrayaan-1 is also scheduled to send a probe to the moon's surface."

Iddo Genuth writes to tell us that Samsung and Unidym have shown the world's first carbon nanotube-based color e-paper. Interestingly, the new film is electrically conductive while remaining almost completely translucent and only 50 nanometers thick. "The company also mentions that the EPD [electrophoretic displays] has important advantages over conventional flat panel displays. EPDs have very low power consumption and bright light readability, which means that even under bright lights or sunlight, the user would be able to view the display clearly. Furthermore, since the device uses the thin CNT films, applications can include e-paper and displays with thin, flexible substrates. Power consumption is lowered due to the EPD's ability to reflect light and therefore able to preserve text or images on the display without frequently refreshing."
