History of Space Travel
Space travel has been a topic of interest for humans since ancient times. However, it wasn’t until the 20th century that space travel became a reality. The early years of space travel were marked by significant achievements and setbacks.
Early Years of Space Travel
The first successful launch of a human-made object into space was the Soviet Union’s Sputnik 1 in 1957. This event marked the beginning of the space race between the United States and the Soviet Union. The following year, the Soviet Union launched the first human, Yuri Gagarin, into space, making him the first person to orbit the Earth.
In 1961, the United States launched its first human, Alan Shepard, into space. The United States continued to make significant strides in space exploration, including landing a man on the moon in 1969.
Space Race Between USA and USSR
The space race between the United States and the Soviet Union was a competition for supremacy in space exploration. The two nations engaged in a series of space missions, each trying to outdo the other and gain a technological advantage.
The Soviet Union gained an early lead in the space race, launching the first satellite, animal, and human into space. However, the United States eventually caught up and surpassed the Soviet Union in space exploration. The United States was the first to land a man on the moon and establish a space station.
