Human space exploration helps to address fundamental questions about our place in the universe and the history of our solar system. through (address) the challenges related to human space exploration we expand technology, create new industries, and help to foster a ) connection with other nations.the first step in embarking on a long and ) journey involves laying solid groundwork for a (success) endeavor. the international space station serves as a national laboratory for human health, ), and materials research, as a technology test-bed, and as a stepping stone for going (far) into the solar system. on the international space station we will improve and learn new ways to ensure astronauts are safe, healthy and (product) while exploring, and we will continue expand our (know) about how materials and biological systems behave outside of the influence of gravity.the aim of the iss is for the astronauts to carry out experiments in such fields as physics, astronomy and meteorology. work on board the station involves (test) space equipment and it will help to prepare for space missions to the moon and mars. in addition, the station is involved in educational programmes and encourages young people to become interested in science and space. сделать, нужно!

Russian national suit is being used from ancient times and until present. it has notable features depending on region. can be festive or casual. distinctive feature of russian national suit - huge amount of clothes. clothes can be union and swing. suits of majors were made of expensive fabrics, with applications of gold, silver, pearls, costly buttons. such suits were passed by inheritance. style of the outfit haven't been changed by centuries. definition of fashion didn't exist. russian national suit became less popular when peter i in 1699 has forbidden wearing of russian national suit for everybody, except rednecks, monks, priests and lectors. base for a man's suit was a shirt or undershirt. over the shirt men put on zypun made of home cloth. base for the woman's suit was long shirt. shirts used to be decorated with fringes or embroidery, sometimes with pearls. married women should have necessarily  cover their hair, thus they wore volosniks and povoyniks and binded their hair with shawls, and when leaving the house they put on ornated kiks or kokoshniks.

From ancient times people were afraid of natural disasters. these unpredictable disasters killed thousands of people and destroy dozens of cities. it was called "the punishment of the gods". all of these is about the earthquakes. today we can explain what the earthquake is, why it occurs and even define the earthquake-prone areas. so, why do earthquakes happen? scientists say that the reason is the movement of tectonic plates of the earth, taking place because of the volcanic eruptions or underground explosions.  over the past decade we have seen a number of seismic disasters in japan, china, chile, thailand, mexico and in other countries all over the world. in other words, the strongest earthquakes with the disastrous consequences cannot be controlled by a man, but they can be highly predicted. nowadays there are many ways to reduce the damage to a minimum. we use special materials while constructing buildings or applying special architectural solutions as well as long-term or short-term forecasting of probable earthquakes. to conclude, today the earthquakes are much less threatening than fifty years ago. they are no longer considered as the punishment of the heaven, just like a natural phenomenon like rain or fog.
