Space Tech

WALA(we are learning about): Space technology.

I read from this website and here's a short explanation about it.

For a long time people have dreamed about going to space. The earliest work on rockets engines were  designed for spaceflight occurred during the early 20th century in three countries by three scientists. In Russia, by Konstantin Tsiolkovsky; in the United States, by Robert Goddard; and in Germany, by Hermann Oberth. On October 4, 1957 the soviets launched the first artificial satellite called Sputnik 1. Four years later, Yuri Gagarin became the first human to orbit the earth in Vostok 1. His last flight took 108 minutes with an altitude of 327 kilometers(that’s about 202 miles).
