In NASA completed the preparatory work with a mini-satellite IceCube, which will be sent to the ISS on 19 March. As reported in NASA, this little device is the first project of this kind under the control of Goddard Space Flight Center. Then the unit will test two weeks, and then sent into space in a solo flight. IceCube weighs 4.5 kg and is 10 cm in width and length and 30 cm in height. It is a full spacecraft. The device is designed for measuring the Earth's atmosphere at altitudes up to 15 kilometers for the content of ice. These measures are necessary for the development of models of changing weather and climate.
