Welcome to Lesson 2!
You have already seen different pictures related to Humans and Space and you have discuss about them with your partners. Read the following texts to know more. Once you finish, complete the exercises porposed and read the information regarding the visit to the Hemisferic that we have programmed for the next Lesson.
1. Apollo 11 - A mission to the Moon
On July 20, 1969, it took place the Apollo 11 mission. American astronauts Neil Armstrong (1930-2012) and Edwin “Buzz” Aldrin (1930-) became the first humans ever to land on the moon. About six-and-a-half hours later, Armstrong became the first person to walk on the moon. As he set took his first step, Armstrong famously said, “That’s one small step for man, one giant leap for mankind.”
Aldrin joined him on the moon’s surface 19 minutes later, and together they took photographs of the terrain, planted a U.S. flag, ran a few simple scientific tests and spoke with the President of the United States. By 1:11 a.m. on July 21, both astronauts were back in the lunar module and the hatch was closed. The two men slept that night on the surface of the moon, and at 1:54 p.m. the Eagle began its ascent back to the command module. Among the items left on the surface of the moon was a plaque that read: “Here men from the planet Earth first set foot on the moon–July 1969 A.D–We came in peace for all mankind.”
2. The International Space Station
The International Space Station is a large spacecraft that orbits around Earth. It is a home where astronauts live and also a science lab. Many countries worked together to build it. They also work together to use it.
The space station is made of many pieces. The pieces were put together in space by astronauts. The space station's orbit is about 220 miles above Earth. NASA uses the station to learn about living and working in space.
People have lived in space every day since the year 2000. The space station's labs are where crew members do research. This research could not be done on Earth. Scientists study what happens to people when they live in space. NASA has learned how to keep a spacecraft working for a long time. These lessons will be important in the future, because NASA has a plan to send humans deeper into space. The space station is one of the first steps.
3. Valentina Vladimirovna Tereshkova, the first woman to travel to space.
She is a retired Russian cosmonaut, engineer and politician. She was the first woman to have flown in space, having been selected from more than 400 applicants and five finalists to pilot Vostok 6 on 16 June 1963. She completed 48 orbits of the Earth in her three days in space.
Tereshkova was born in central Russia. Her parents had migrated from Belarus.Tereshkova's father was a tractor driver and her mother worked in a textile plant. Tereshkova went to school in 1945 at the age 8.
Even though there were plans for further flights by women, it took 19 years until the second woman, Svetlana Savitskaya, flew into space.
4. Space debris, a danger to humans and environment
Space debris, junk, waste, trash, or litter is the collection of defunct man-made objects in space – old satellites, spent rocket stages, and fragments from disintegration, erosion, and collisions – including those caused by debris itself. As of December 2016 there were 5 satellite collisions with space waste
Is not easy to remove this debris, because no technology at the moment would allow us to vacuum up this stuff to clean up space. So it’s a bit of a waiting game. Hopefully the smaller bits of debris will continue to be braked by the atmosphere and burn up on the way back down but that only works for junk in orbits of perhaps 300 or 400 kilometers.
The high stuff could take centuries to come down.
