Small satellites have many advantages, small risk, low cost, can also be applied to other large projects, they can be used to do flight test, but also to use the constellation and small satellite group to expand the scope of scientific observation.
NASA plans to launch a series of new generation of small and micro micro included in the earth's orbit, used to study climate models and climate change. This task is not only of great significance to scientific research, but also represents the advanced technology needed to launch a small and low-cost satellite. NASA held a meeting in November 7th to discuss the plan to launch a small satellite in a few months. Stofan Ellen, chief scientist at NASA headquarters, said the small satellite could reduce the cost of the earth's equipment in space. Moreover, these satellites can also provide more research into space for private enterprises, but also help to further understanding of the earth's orbit of the University and students to learn more about space.
Small satellites have many advantages, small risk, low cost, can also be applied to other large projects, they can be used to do flight test, but also to use the constellation and small satellite group to expand the scope of scientific observation. For example, the hurricane global navigation satellite system consists of 8 tiny satellites (CYGNSS) is scheduled to launch in December 12th, will fly over the display arrangement in high incidence area of earth hurricanes, climate change monitoring, improve weather forecasting ability. Another example is the vertical carbon nanotube radiation assessment (RAVAN) project, which aims to use several orbiting satellites to cover the globe, to monitor the greenhouse effect and the earth's climate change. The first RAVAN is a three in one cube satellite CubeSat, which is expected to be launched at the end of this month.
Another time resolved observation (TROPICS) of the precipitation structure and the intensity of the storm, the satellite group composed of 12 CubeSat will study tropical cyclones, while tracking the atmospheric pollution. Each satellite will use a radiation detection device to measure the characteristics of the water vapor in the air and the storm. The new project marks a new era in satellite technology. These tasks mentioned above may pave the way for future launch of a mini satellite group of objects in the moon, Mars, or other solar system.
