Tiangong 1 will perform spectral detection of the earth

On October 4, the reporter learned from China’s manned space engineering network that Zhang Shancui, the deputy chief designer of the space application system for the manned space project, said that Tiangong 1 will arrange for the development of space materials science, space environment exploration and earth observation. Space scientific experiments. In earth observation, Tiangong-1 will experiment with a high-resolution spectral camera to perform spectral detection on the Earth.

Spectral observation equipment pays attention to the experimental nature According to reports, the Tiangong-1 Earth observation will be the first experiment using short-wave infrared spectrometers. The earth observation equipment used on the Tiangong-1 will be different from the satellite-borne earth observation equipment used by remote sensing satellites. The latter will use The technology and equipment have a high degree of maturity and can be directly applied; the former focuses on the nature of the experiment, and the observation equipment will be used for satellites after the success of the experiment.

Zhang Shanci said that in the future, China’s manned space station will also be a state-level space laboratory that has been taken care of for a long time and will support the development of dozens of academic experiments in space.

Detection equipment resolution up to 10 meters It is reported that currently Tianmu No. 1 has entered the near-round orbit from the ground 354 kilometers, and launched on-orbit testing.

Zhang Shan from the introduction, such as the recent oil spill in the Bohai Sea, the ordinary camera can not see the changes in the sea, through the spectrometer can detect the impact of oil spills in the sea area, as well as the destruction of the marine ecological environment.

It is reported that this kind of spectral camera is the first type of short-wave infrared spectroscopy detection equipment in China, and it is also the highest spatial resolution device in the country. Its spatial resolution is up to 10 meters, and the spatial resolution of the same type of instruments in foreign countries is On the order of 100 meters, it is even on the order of 1,000 meters.

It is reported that in space materials science, composite colloidal crystal production experiments will be conducted. The production of composite colloidal crystals is currently a hot spot for scientific research in space materials. One of the most representative is the photonic crystals, which is compared to the 21st century may bring information technology. New revolutionary material.
