1 On 10 February 2009, at a height of about 800 kilometers above Siberia, an American satellite collided the first such height [háit] satellite [séetalait] collide(d) [kaláid(id)] with an old Russian satellite. It was collision [kaligan] collision in the history of space development. As a result, fragment(s) [fráegmant(s)) debris [dabri:] more than 1,000 fragments of debris were scattered into space. 2 The image above shows the vast amount of space debris in orbit around Earth. Approximately 22,000 vast [váest] orbit [5:rbat] approximately [aprá:ksamatli) objects larger than 10 centimeters across are floating around Earth. Of these, about 16,000 are from known 10 considering [kansidarig) artificial [a:rtafijal] currently [ks:rantli] operation [a:paréifon] Considering that there are only about 1,000 artificial satellites currently in operation, the amount of Sources. space debris is astonishing. This space debris is not only due to the collision of satellites. For example, when rockets reach space, they s 15 leave behind surplus engines and fuel tanks. These objects remain in orbit as space debris. In addition, surplus s5:rplas] there are tools that astronauts have dropped while tool(s) [t:l(z)) astronaut(s) [astrand:t(s) aluminum [ala:manom per|par] working outside. Even a one-centimeter aluminum ball. when orbiting at a speed of around 10 kilometers per 0 bullet [bálat] second, is far more powerful than a bullet from a gun. gun [gán]

Today, one of the hottest environmental issues abroad is bottled issue(s) [ju(z)) water. Not only does the bottled water industry cost the industry[indastri] planet a great deal in energy and materials, it has become a symbol of First World excess. deal di:!] excess[iksés] ironic lairá:nik] wealthy [wélli] willing[wilig) 2 It is ironic that, although consumers in wealthy countries have safe drinking water, they are willing to pay up to 100 times more for bottled water because of clever packaging [pekidsig] packaging and attractive names.

When space debris damages a satellite, the satellite other satellites. Through this chain of destruction, space itself becomes space debris, which may then collide witt destruction (distrákjan] explosively iksplousivli impossible impd:sobl] debris is increasing explosively and may eventually make the development of space impossible. 5 Under one plan to clean up space debris, a hunter rotating [routéitigl <rotate droplet(s) [drá:plat(s)] rotation [routeijan] stretch(es) [strétf(iz)] satellite approaches a rotating piece of debris. It shoots water droplets at the debris in order to stop its rotation. and then attaches a tether to it. As the tether stretches brake [breik toward Earth, it acts as a brake. The debris loses speed and height and eventually burns up in the atmosphere. 6 Artificial satellites are indispensable in our daily lives. indispensable [indispénsabl] They support the GPS functions of smart phones and car navigation [navogeifan] navigation systems. They are used to make weather observations, which have become even more important observation(s) (a:bzarvéijm(z)} abnormal [ebn5:rml] with the global increase in abnormal weather conditions. relay[i:lei Also, they relay a rich variety of TV programs for our enjoyment indsimant」 enjoyment and education.
