    With the first flower on the moon's surface, it may not be a dream for humans to move to the moon.
    , organized by the Joint Research Center for Deep Space Exploration of the Ministry of Education and led by Chongqing University, will be one of the "passengers" of the Chang'e-4 to land on the lunar surface in 2018 for the first human lunar biological experiment, which will be broadcast live around the world.
    Only 3 kg weight of the "Qiankun" tank "moon surface micro-ecological circle" is a special aluminum alloy material made of cylindrical "can", 18 cm high, 16 cm in diameter, net volume of about 0.8 liters, a total weight of 3 kg.
    cans, though small, can contain "the whole world" inside. Professor Xie Xuan, deputy director of the
    Deep Space Exploration Center and director of the Institute of Advanced Technology at Chongqing University, said the "can" carrying the moon on The Fourth will contain seeds and eggs from two plants, as well as elements needed for the growth of plants and animals such as soil, nutrients and air, as well as miniature cameras and cameras that record the growth of plants and animals, air conditioners that regulate temperature, and batteries that provide energy.
    In the jar, potatoes and amoeba will absorb natural light from the moon's surface through light ducts for photocoupulation, releasing oxygen for the "consumers" in the ecosystem - silkworm eggs, which then excrete carbon dioxide and household waste to provide plant seeds, cycle back and forth, and the small ecosystem begins to take shape.
    although the small jar weighs only 3 kg, but it contains 40 parts, the cost of more than 10 million yuan.
    has gathered the wisdom of multidisciplinary research and development teams in machinery, control, environment, biology, materials, energy, optics, communications, etc., and created a variety of new technologies.
    three "passengers" selected thousands of times last year, U.S. astronaut Scott Kelly bred a 100-day chrysanthemum at NASA's space station, becoming the first flower to open in outer space.
    time our country will bring the moon flowers will be potato flowers or amoeba mustard flowers.
    why did we choose potatoes, amoeba, silkworms, three Earth "passengers" to the moon? "This is the result of thousands of screenings.
    " Xie explained that because of the limited resources in the "can", it is required that the animals and plants inside can not take up too much space.
    which plants and animals can land on the moon, the first condition is "small."
    Second, because the moon does not have the atmosphere to transmit heat, day and night temperature difference is large, in the capsule temperature control in the 30 degrees C to -60 degrees C, "can" temperature control at a minimum of -10 degrees C, so the requirements of animals and plants can withstand high temperature, freezing, and radiation and interference resistance.
    is a familiar food and is likely to be a staple food in space in the future, ' Mr. Xie said.
    the potato of choice is a specially bred "small" variety.
    the short period of amoeba flowering, from germination to flowering only 1 month, is a good experimental model plant, so the task of opening the first flower on the moon was given to it.
    silkworm eggs will complete the full life cycle of egg hatching, larvae growth and development, and breaking into butterflies in the ecosystem.
    is an important reason why silkworms are chosen because they carry traditional Chinese culture.
    to verify photocooperation on the moon" This experiment is mainly to observe photocooperation on the moon and to popular science.
    " Xie updated the introduction, through the "moon micro-ecosystem" to observe the low gravity, strong radiation conditions of plant seed germination, seedling growth and flowering of the whole process, or worm egg hatching, larvae growth and development, break into a butterfly, to verify the moon environment seed breathing effect and plant photocooperation.
    earth, the moon takes 28 days a week to turn around.
    day on the moon is equivalent to 14 days on Earth, when these plants and animals will spend 14 consecutive days on the moon and then enter 14 nights.
    " we will introduce natural light from the lunar surface through light condors to realize the use of the moon's in-place resources, so that plants and animals fully accept the moon's light environment.
    " Xie said he had previously considered using artificial light to simulate the light environment on Earth, but using the moon's own light would be more significant for the experiment.
    if plants and animals can adapt to the moon's light for growth, then humans can build bases on the moon and carry out long-term scientific research, which is of great significance to the future survival of mankind on extraterreterorded planets.
    the temperature in the jars will remain between -10C and 30C, and potatoes, auspyro-mustard and silkworms will be micro-ecologically recycled inside, Mr. Nai said.
    that they expect three 28 days to be able to successfully open the first flower on the moon.
    technical difficulty lies in the temperature control of the back of the moon, which arrived on the fourth day of the year, 380,000 kilometers from Earth.
    lunar environment vacuum, daytime temperature can reach more than 100 degrees Celsius, night minus 100 degrees Celsius, coupled with micro-gravity, solar radiation, high-energy particle impact, etc. , to the experiment brought considerable difficulties.
    the difficulty of the "Kopp load moon microsphere" lies in temperature control and energy supply.
    " Xie said, because the capsule does not power the "cans", so they need to solve their own energy problems.
    in order to keep the temperature in the "can", they put on insulation and air conditioning for the "moon microsphere".
    but this air-conditioning is not ordinary air-conditioning, is the application of Chongqing University in the building temperature control advantages developed a new type of air-conditioning.
    solar cells can be used for temperature control, to ensure that the micro-ecosystem and cameras and other power-consuming equipment work.
    she said it would take about two months from the time the launch was ready to fly to the moon.
    to keep plants and animals from growing on the way, they conducted extensive experiments to ensure that they sleep during the journey and are awakened when they reach the moon.
    he said that after launch, human remote control can not be operated, only through cameras and sensors to observe.
    , they will use video to observe the growth of plants and animals, using sensors to detect the temperature inside, live broadcast to the world.
    it is understood that the popular science load has been more than two years of experiments, is expected to complete the official product in September this year, the end of next year launch.
    In addition to Chongqing University, Hunan University, Beijing University of Aeronautics and Astronautics, China Aerospace Science and Technology Group and other universities and enterprises are also involved, involving machinery, control, environment, biology, optics, energy and other multidisciplinary research and development teams, many of which will be used for civilian use in the future.
