The development of mechanical NASA nose: trying to "sniff out" signs of life on Mars in order to probe into the faint signs of life on Mars, NASA (NASA) laser radar technology has developed a mechanical nose based on scientists. Sina Technology News Beijing on November 5th, according to foreign media reports, in order to detect the slightest signs of life on Mars, NASA (NASA) scientists developed a mechanical nose. However, this device is completely different from our body’s nose, but a device based on laser sensors, has been used in the military to detect the threat of biological weapons. Scientists at the Goddard Space Flight Center in the United States have announced that they will use the technology in future exploration of Mars and other parts of the solar system. In the remote detection system combined with biological weapons, the United States Department of defense "(Joint Biological Standoff Detection System) based on NASA, scientists have developed" signs of life of laser radar detector (Bio-Indicator Lidar Instrument), referred to as BILI. The instrument is not a direct confirmation of the existence of life, but the ability to search for amino acids and other organic molecules needed for life in the environment. BILI will not be used to detect bacterial or chemical weapons in space. The Goddard Space Flight Center likened it to the smell of the vehicle, as if NASA had sent a beagle to mars. "Before the planetary surface exploration, NASA has never used this instrument," technical personnel, NASA had worked in the development of the biological detection instrument with the secret department branimir · Prague Vic (Branimir Blagojevic) said. "If there is a biomarker (there are traces of organic matter on Mars)," he said, "it can be detected in the dust." As indicated by the name "BILI", the instrument needs to be operated by lidar. Laser radar (Lidar) is very close to active radar in technology. The radar produces radio waves, and the lidar uses a laser pulse – in short, light. The principle of laser radar and conventional radar systems is the same: the instrument sends a signal, reflected in the goal, is received by the receiver; then, the instrument will what is according to the signal interpretation of the object returned by the. In fact, the principle of this instrument is closer to the use of ultrasound positioning of the bat, rather than the beagle. Lidar derived from twentieth Century to 60 in 70s, the advent of laser sensors, has a very wide range of uses. Auto companies, including Google, are evaluating the use of lidar to detect and avoid obstacles. NASA has also used the lidar to observe the chemical composition of the earth’s atmosphere. NASA recently released this laser radar system is issued by the UV laser pulse. The wavelength of this beam is too small to be seen by the naked eye相关的主题文章:
