Aviation & Avionics, Thursday December 4, Period 2
Murdock had a large bowl of candy, many of them of the holiday variety, sitting out on his desk.
Probably best not to ask where they came from.
Like his shoes.
"Hey class," he grinned. "Wow, hard to believe the semester is almost over. I hope y'all have been taking notes 'cause there's supposed to be some kind of test thing y'all have to take."
He may not have realized that part when he first started teaching. Ah, ooops?
"It shouldn't be too hard, though. Anyway, we got one more thing to cover first. Space Flight!"
(ocd up!coming!)

Lecture! (there's only one part, omg!)
The first human spaceflight was Vostok 1 (http://en.wikipedia.org/wiki/Vostok_1), carrying 27 year old Russian cosmonaut Yuri Gagarin on April 12, 1961. The spacecraft completed one orbit around the globe, lasting about 1 hour and 48 minutes. Gagarin's flight resonated around the world; a demonstration of the advanced Soviet space program and it opened an entirely new era in space exploration; human spaceflight. The U.S. first launched a person into space within a month of Gagarin's flight with the first Mercury flight (http://en.wikipedia.org/wiki/Project_Mercury), by Alan Shepard. Orbital flight was achieved by the United States when John Glenn's Mercury-Atlas 6 (http://en.wikipedia.org/wiki/Mercury-Atlas_6) orbited the Earth on February 20, 1962. Valentina Tereshkova was the first woman in space, orbiting the Earth 48 times aboard Vostok 6 on June 16, 1963.
The first successful orbital launch was of the Soviet unmanned Sputnik (http://en.wikipedia.org/wiki/Sputnik_1) mission on October 4, 1957. The satellite weighed about 184 pounds (83 kg), and is believed to have orbited Earth at a height of about 150 miles (250 km). It had two radio transmitters (20 and 40 MHz), which emitted 'beeps' that could be heard by any radio around the globe. Analysis of the radio signals was used to gather information about the electron density of the ionosphere, while temperature and pressure data was encoded in the duration of radio beeps. The results indicated that the satellite was not punctured by a meteoroid. Sputnik 1 incinerated upon re-entry on January 3, 1958.
While the observation of objects in space, known as astronomy, pre-dates reliable recorded history, it was the development of large liquid-fueled rocket engines during the early 20th century that allowed physical space exploration to become a reality. Common rationales for exploring space include advancing scientific research, uniting different nations, ensuring the future survival of humanity and developing military/strategic advantages against other countries.
Space exploration has often been used as a proxy competition for geopolitical rivalries such as the Cold War. The early era of space exploration was driven by a 'Space Race' between the Soviet Union and the United States; the launch of the first man-made object to orbit the Earth, the USSR's Sputnik 1, on October 4, 1957, and the first Moon landing by the American Apollo 11 (http://en.wikipedia.org/wiki/Apollo_11) craft on July 20, 1969, are often taken as the boundaries for this initial period. The Soviet space program achieved many of the first milestones, including the first human spaceflight in 1961, the first spacewalk in 1965, and the launch of the first space station, Salyut 1 (http://en.wikipedia.org/wiki/Salyut_1) in 1971.
After the first 20 years of exploration, focus shifted from one-off flights to renewable hardware, such as the Space Shuttle program, and from competition to cooperation as with the International Space Station. From the 1990s onwards, private interests began promoting space tourism and now private space exploration of the Moon. In the 2000s, China initiated a successful manned spaceflight program, while Japan and India also plan future manned space missions. Larger government programs have advocated manned missions to the Moon and possibly Mars sometime after 2010. (http://en.wikipedia.org/wiki/Valentina_Tereshkova) ()

Also, waaaaay too frickin' cold over here.
