Kindly allow me the prejudice of summing up my own generation: We think the Earth orbits around us.
The difference arises mainly because Iridium's satellites are both more numerous and use more power to maintain their low-earth orbits.
In A Study in Scarlet, the first-ever Holmes adventure, Dr. Watson realizes that Holmes was unaware that the earth orbits the sun.
The largest, the 53m-long Falcon 9, is scheduled to launch in late 2007, and should be able to carry about 25, 000kg into low-Earth orbits.
BBC: The new Falcon 1 rocket has been lost on its maiden flight.
The dish would send the ISP's data up to one of the satellites (in low earth orbits to minimize signal delay), which would then relay the data back down to a backbone access point.
The play stars Ian McDiarmid - returning to the RSC after an absence of 27 years - as the 17th Century scientist who challenges the Catholic church with his assertion that the Earth orbits the Sun.

It is not circling the Earth but orbits a point in the Sun-Earth system called the second Lagrange point.
It has five times the mass of the Earth and orbits its star every 13 days.
It is 70% larger than the Earth and orbits Kepler 69 once every 242 days -- very like Venus.
They say they have strong evidence for another planet in the same system that has about eight times the mass of the Earth and orbits every 84 days.
That means that the same spot on the Earth being observed will have consistent lighting as the satellite orbits the Earth, making it easier to see changes over time.
Near-Earth objects are comets or asteroids in orbits that allow them to enter Earth's neighborhood.
The asteroid poses no danger to the 400 or so satellites in higher orbits around Earth, agency officials said.
After that he'll be at Russia's mission control where he can talk to his son as he orbits the Earth.
And once the planets lined up in their orbits, Earth would "overtake" the others, meaning that Jupiter and Saturn would appear to change direction in the night sky.
The results suggest that 17% of stars host a planet up to 1.25 times the size of the Earth, in close orbits lasting just 85 days or fewer - much like the planet Mercury.
Most are transient visitors to the vicinity of earth their orbits are so long that many of those arriving now (such as Hale-Bopp) must have made any previous visit to the inner solar system before the beginning of recorded history.
With all three vehicles, Arianespace, the company that runs Kourou, will now be able to offer satellite operators a ride for any type of spacecraft to all kinds of orbit - from the low, pole-crossing orbits used by Earth observation missions, to the high, geostationary locations favoured by big telecommunications platforms.
Near-Earth objects are asteroids or comets, believed to be remnants from the formation of the planets, whose orbits brings them close to the Earth.
It inflated to 14 feet long by 8 feet in diameter and still orbits 350 miles above Earth.
And the Moon is close by and always in the sky, unlike the asteroids that flyby the Earth at incredible velocities or inhabit orbits tens of millions of miles away that take years to reach.
FORBES: The Moon is a Natural Platform for Asteroid Mining, Detection and Deflection
It was the Apollo group of asteroids, which circle the sun in oblong orbits, that occasionally cross Earth's.
The mission would further clarify the threat that this particular object poses, and better predict the orbits of other near-Earth asteroids, Beshore said.
In contrast, the third Earth-like planet, Kepler 69c, orbits a star very similar to our sun (that is, hotter than Kepler 62).
This is just one of several hundred rocks, varying in size from a few metres to a few kilometres across, whose orbits around the sun cross the Earth's.
Frequent follow-up observations will allow astronomers to track those objects and calculate their orbits, identifying any potential threats to Earth.
BBC: Pan-Starrs telescope begins operations to hunt asteroids
The NASA Near Earth Objects (NEO) Program at the agency's headquarters in Washington, manages and funds the search, study, and monitoring of NEOs, or asteroids and comets, whose orbits periodically bring them close to the Earth.
ENGADGET: PSA: Asteroid 2012 DA14 will pass the Earth at 2:00pm ET Alt
Various countries also have been formulating new rules or guidelines to assure that before satellites completely lose power and no longer can be controlled, operators will abide by plans to park them in out-of-the-way orbits or safely bring them back to earth.
In 2014 it intends to launch, at a cost of a few million dollars, a set of small space telescopes whose purpose will be to seek out asteroids which are easy to get to and whose orbits return them to the vicinity of Earth often enough for the accumulated spoils of a mining operation to be downloaded at frequent intervals.
Satellite and space expert Dr Stuart Eves stressed the large uncertainties involved in tracking the "decay" of satellite orbits (their slow fall back into the Earth's atmosphere).
