Expert Sharon on 17 prospects in the Academy space technology
Satellite "country", the "little man" is also unique charm. Reporter from the Shanghai Academy of Sciences Center 17 Academy hosted the first 34 Sharon was informed, and even micro-satellite Nano Satellites can play a great future space exploration.
Build a small role in a large
Small satellites, according to Shanghai Project Center Deputy Director Yang Genqing description, weight less than equal to 1000 kg satellites, small satellites can be classified in the family; less than 100 kilograms, referred to as micro-satellites; and nano-satellites, weighing only 10 kg; the future, even 1 kg heavy leather satellite. Satellite family, the "little man", no small role, communications, Earth observation, astronomical observations, technical testing, scientific experiments in the field has its useless. More small satellites, to achieve a m ajor satellite functions; a large satellite can not complete the mission, but many small satellites can be done.
With flying "big man"
Most interesting is that small satellites can also fly with a large satellite, such as the International Space Station INS PE CT OR satellite. Responsible for flight with small satellites, often similar to concentric circles along the track of the large satellite "hot pursuit", suddenly, after the former suddenly, fluctuated, closely "monitoring" big satellite's every move. The original, it's real task is to inspect satellite at various times of the working state, while its costs are only a few one-tenth of a large satellite. Separation of large satellites and rockets are smooth? Into orbit is working? Solar array has no time to open? These are associated with flying small satellites to operate in the heart. It is reported that large and small satellites can be multi-satellite launch vehi cle into space; small satellites can also take a large satellite "ride", by the person with extravehicular astronauts after the spacecraft and camera to take photographs in extravehicular activities, and to help the spacecraft orientation.
Air "play Rubik's cube"
According to earlier reports, from the Shenzhou VII, China will begin the second step of manned spaceflight program, the establishment of short-term manned space laboratory, and laboratory space on the release of small satellites, the relative space experiments chamber formed with formation flying. The release of small satellites on the meter is equivalent to expanding the space to experiment a few kilometers of space, which in addition to the space environmental monitoring, basic science experiments, but also can carry out laser Communication Test.
Imagine, if there are several micro-satellites as a child star sodium satellite, regar dless of whether they performed the same task or different tasks, organically assembled them in a parent star, the one from the launch vehicle Launch Off, it is not the equivalent of sending a "space aircraft carrier"? Even more commendable is that Micronanoelectronic like this satellite station in the air as flexible as the Rubik's Cube combinations: solo, network, formation, accompanied by flight, fault diagnosis, Transport Service , Or simply like a great big integrated satellite-like work. According to Shanghai Jiaotong University, vice president of space technology segment Teng Ping said, the design of the hospital is now able to accommodate 3?? 6, each weighing about 15 kg child star of the multi-function smart satellite station.
