In this summary I am going to focus on space environment which is a branch of astronautics, aerospace engineering and space physics that seeks to understand and address conditions existing in space that affect the design and operation of a spacecraft. Also, I am going analyze aspects of the space environment.

KEY TERMS

SUMMARY
 The origins and fate of life on Earth are intimately connected to the way the Earth responds to the Sun’s variations. We live in the extended atmosphere of an active star where the solar activity and the space magnetic storms affect in various ways human life. Solar conditions are favorable for the development of electromagnetic disturbances in geospace, which can effectively influence the performance and reliability of space and ground-based technological systems. Space weather influence on the Earth’s weather and climate is still a developing topic. Moreover, little is known concerning the biological effects of space weather, especially regarding astronauts.
A related subject with space environment is space weather which deals with dynamic processes in the solar-terrestrial system that can give rise to effects on spacecraft, but that can also affect the atmosphere, ionosphere and geomagnetic field, giving rise to several other kinds of effects on human technologies. Space weather effects on Earth can include ionospheric storms, temporary decreases in ozone densities, disruption to radio communication, to GPS signals and submarine positioning. Space debris and meteoroids can impact spacecraft at high speeds, causing mechanical or electrical damage. The average speed of space debris is 10 km/s while the average speed of meteoroids is much greater. Space weather is distinct from the terrestrial weather of the Earth's atmosphere. The science of space weather is focused on fundamental research and practical applications. The term space weather was first used in the 1950s and came into common usage in the 1990s.
Vacuum is also the one of aspects of the Space environment. The hard vacuum of space will cause outgassing, which is the release of volatiles from materials. The outgassed molecules then deposit on line-of-sight surfaces and are more likely to deposit on cold surfaces. This molecular contamination can affect optical properties of vehicle and payload surfaces and spacecraft performance, particularly for sensitive optics.

The History of Genetic Engineering By Goda Ponomariovait ė Introduction In this summary, I will present a short timeline of genetic engineering history. The genetic modification has started many centuries ago in agriculture because people wanted to make their crops more fertile. Nowadays genetic engineering is more improved. Not long ago genetic organisms and food appeared. Human clones were also developed. Key terms Genetic engineering - is the process of altering the DNA in an organism’s genome. https://www.yourgenome.org/facts/what-is-genetic-engineering Genetically modified organism - is any organism whose genetic material has been altered using genetic engineering techniques. GMOs are used to produce many medications and genetically modified foods and are widely used in scientific research and the production of other goods. https://en.wikipedia.org/wiki/Genetically_modified_organism Manipulation in chemistry -    create/generate, shape and manipulate chem

Aušrinė Tunkevičiūtė Part 1 INTRODUCTION The main subject which I am investigating is exercising. This term has a lot of meanings and all of them is necessary. It includes any movement from stretching to professional sport. Generally, it can be said that exercising could be any form of movement, but what I will mainly focus on is strolling, jogging, dancing and home exercising. In all the articles I will look for any evidence that exercising has a great impact on human psychology. It may be said that sport has two sides, but I am convinced that exercise perfomed correctly and steadily bears only benefits which I hope will be approved in my pilot study. The thesis I am doing is as following “Exercising makes a person happier”. KEY TERMS ·      Exercising – physical activity that people involve in everyday life in a game, duty, hobby or purpose form. People exercise when they play sport games like volleyball, do special exercises at home, attends professional sport leag

Urt ė Stankevičiūtė Part 2 INTRODUCTORY PART Together with my co-partners we are conducting a pilot study on the thesis “ “Exercising makes a person happier”. I am interested how literature reflects a particular aspect of it, i.e. how physical activity impacts mental health with the aim to find out how exercising or any kind of movement helps to deal with stress, depression and other mental issues whereas my colleague will concentrate more on the previous studies which reveal the positive effect of exercising in general ( see article by Aušrinė Tunkevičiūtė) KEY TERMS Mental issues (Mental illness) – mental illness refers to a wide range of mental health conditions – disorders that affect your mood, thinking and behavior. Anxiety – distress or uneasiness of mind caused by fear of danger or misfortune. Depression – a state of feeling sad (anger, anxiety); a mood disorder marked especially by sadness, inactivity, difficulty in thinking and concentration, a significant in
