“Modern” Astronomy
Typically the end of the discussion, but…….
In Newton’s time, there were 6 planets
The Age of Sight
James Bradley (1725) – observes stellar parallax. The end of the geocentric
universe.
William Herschel (1781) – discovers Uranus
Messier (1781) - discovers galaxies, nebula and star clusters while looking for
comets. He compiles a catalogue of these objects (Messier objects).
Christian Doppler (1842) – Discovers the “Dopple Effect”
Johann Galle (1846) – Discovers Neptune
Sir William Huggins (1860) – Initiates spectral analysis of starts
Shiaparelli (1877) – Catalogs canals on Mars
The Wright Brothers (1903) – First Powered Flight
Robert Goddard (1926) – Foundations of rocketry
Clyde Tombaugh (1930) – Discovery of Pluto

Deep Sky
Astronomers have used the Hubble space telescope to discover the faintest and
most distant galaxies ever seen. A new camera fitted to the orbiting observatory in
May by shuttle astronauts has captured dim red "star cities" that formed only 600900 million years after the Big Bang. 2009
Commercial
Enterprise
On June 21, 2004, … the launch of SpaceShipOne, the first private-venture
craft to attempt to leave the earth's atmosphere and enter space, defined as an
altitude of 100 kilometers (62 miles).
Virgin Galactic
The one space tourism venture that has garnered the most interest in recent
months, however, has been Virgin Galactic. Days before the first Ansari X Prize
flight, Virgin announced it was partnering with Scaled Composites and Mojave
Aerospace Ventures—the joint venture of Scaled and financier Paul Allen—to
create a suborbital space tourism business flying vehicles based upon
SpaceShipOne. Since then the company has released few details about its plans:
the news section of Virgin Galactic’s web site was last updated on October 4,
when SpaceShipOne made its final, prize-winning flight.
However, during Saturday’s sessions of the National Space Society’s International
Space Development Conference in Arlington, Virginia, Virgin Galactic executives
offered a host of new details about their plans for suborbital spaceflights and
beyond.
The Virgin Galactic experience
Even though the first commercial flights of Virgin Galactic’s SpaceShipTwo are still
nearly three years away—spring 2008 under current plans—the company has paid
considerable attention to the experience its customers will have. “What we’re
doing is giving you a two-hour experience of going into space that will only require
a few days of training,” said Will Whitehorn, president of Virgin Galactic. - 2005
December 8, 2009—Aspiring space tourists got a first look at their future ride late Monday, when Virgin Galactic
unveiled the first of its long-awaited SpaceShipTwo planes (pictured with wings folded upward, suspended from the
middle of its twin-fuselage launch vehicle). Projected fare = $200,000.00
