What is the velocity of the ISS?
According to NASA, it is 7706 m/s.

Newton and Galileo disagree.
The ISS “like any orbiting object, it is in continuous freefall" -wiki
Acceleration due to gravity (g) at the 400km altitude of the ISS is
8.69 m/s2.

There is no terminal velocity in space as there is no wind resistance to balance gravitational pull. (by definition of space vacuum)
As of June 26, 2013, the ISS has been in orbit for 5332 days or
460,684,800 seconds. -wiki
Having accelerated 8.69 m/s2 for 460,684,800 seconds in the vacuum of space the ISS should have a current velocity of ~ 4,003,350,912 m/s or just over four million kilometers per second or more than 10 times the ‘speed of light’ (c).
The math is correct. 5332*24*60*60 = 460,684,800 seconds *8.69g = 4,003,350,912 m/s =
4,003.351 km/s.
Please confirm the math for yourself, as well as all facts stated above.
To be exact, we also need to add the initial escape velocity of 11.2 km/s for a grand total of 4,003,362 km/s, but a “velocity of 4 million km/s” should suffice for purposes of this discussion.
Thoughts?
