The last day of Astronomy!Z

Astronomy
Today was a chill day, we first went outside and measure the sun angles. Next we researched about Astronauts. I had John Glenn he was the first American to orbit around the sun, and the third American in space. He flew the Friendship 7 mission on February 20, 1962. He then received the congressional space metal of honor.
