This document summarizes major milestones in space exploration from the past to the present and future. It discusses how Hipparchus created the first accurate star map in 130 BC. It then outlines Galileo's improvements to the telescope in 1609 that allowed him to make discoveries. The document also summarizes the launch of Sputnik 1 in 1957 as the first satellite to orbit Earth and Yuri Gagarin as the first human in orbit in 1961. Major events like the Apollo 11 moon landing in 1969 and Voyager 1 space probe launch in 1977 are highlighted. More recent developments such as the Hubble Space Telescope launched in 1990 and the ongoing International Space Station project are briefly described. The document concludes with details about Virgin Galactic's plans

1. Space Exploration
Past, Present, and Future

2. World’s First Accurate Star Map
• Hipparchus created the
world’s first accurate star
map
• This occurred around 130
B.C.
• He used his own knowledge
of math and observations of
the movements of the stars

3. Galileo and the Telescope
• Galileo Galilei successfully used
the first telescope
• This occurred in 1609
• He made improvements to the
first telescope and was able to
magnify objects 3-30 times
• He used the telescope to discover
4 of Jupiter’s moons, the cycles of
Venus, and was one of the first to
study sunspots

4. First Satellite to Orbit Earth
• The Sputnik Satellite
of the USSR was the
first satellite to orbit
Earth
• This occurred on
October 4, 1957
• A satellite about 58
cm in diameter, about
83.6 g, travelled
29,000 km/hour, it
had a beeping radio
beacon

5. First Human in Orbit
• Yuri Gagarin was the first
human in orbit
• This happened on April
12, 1961
• He used a USSR
developed spacecraft
named Vostok 1

6. Apollo Moon Landing
• NASA sent Neil Armstrong and Buzz Aldrin to the
moon, they were the first men on the moon
• This happened on July 20, 1969
• They flew to the moon in the Apollo 11 space
craft with a moon lander, named “Eagle”

7. Voyager 1 Space Probe
• NASA sent the Voyager 1 Space
Probe into space
• This was sent on September 5,
1977, and is still in space today
• They sent the U.S. robotic
space probe into space, it is
the farthest man-man object in
space, first to leave our solar
system, it has done a detailed
photo study of Jupiter/Saturn,
it also carries a golden record
with details of life on Earth in
case it is discovered by
intelligent life

8. Hubble Space Telescope
• NASA sent out Hubble
• It was launched in 1990
• It was launched from a shuttle, it takes photos of deep
space, it has taken photos that give us the deepest look
into the Universe so far

9. International Space Station
• Americans, Europeans,
Japanese, and Russian space
programs working together
on space station
• Orbit assembly started in
1998 and will in in 2012
• It is the largest artificial
satellite to orbit Earth, can
be seen from the ground
with the naked eye, carries
out research

10. Virgin Galactic Commercial Space
Flight
• Richard Branson/Virgin
Group sends out this flight
• First test in 2010, will send
out flights in the future
• Normal people from Earth
can buy a ticket to travel
to space, cost 200,000
dollars per ticket, it’s a 6
passenger craft, will take
you to space for 6 minutes
