deeptrace writes "Tentatively scheduled for a spacewalk this summer, a Russian cosmonaut will take his trusty six iron and a special weightless-friendly tee and put a golf ball into orbit from outside the International Space Station. The golf ball has an embedded transmitter so that it can be tracked as it orbits. It is expected to orbit for 3 to 4 years before burning up on re-entry. The golf shot is the result of promotional fees paid to the Russian space agency by a Canadian golf club manufacturer."

          Boy, you have no idea how orbits work do you?

          Yes, actually, I do. I'm an aerospace engineer.

          Now Y is moving several thousand miles an hour else it would simply fall to the earth.

          Try several tens of thousands, 17,500 mi/h for LEO.

          It is also moving at several thousand miles an hour, but it's on a reciprocal orbit of the golf ball.

          You didn't read (4). No one uses reciprocal orbits in LEO. Hardly anyone uses reciprocal orbits... ever. The velocity the earth gives you by rotation is significant; working against it is stupid and is used very rarely, and generally only in GEO when you are trying to maintain a constellation of satellites (GPS).

          Now, would you like to guess at the energy transfer of a collision at those speeds?

          Kinetic energy = 1/2 * m * V * V; transfer depends on the elasticity of the collision.

          I'm not stuipd, I just know the assumptions better than you do.

            17,500 mi/h is not even two thens of thousands... dunno about you, but my definition of "several" starts at more than 2 or 3... ;-)

    ok, from TFA:

    "The ball is expected to remain in orbit for three to four years."

    "The ball is expected to travel up to 2.1 billion miles before it drops back into the atmosphere and burns up."

    TFA doesn't say if that distance is based on 3 or 4 years, so I'll work out both and give a max & min average velocity:

    Min time in space = 3 years = 1,096 days (2*365 + 1*366: leap year in 2008) = 26,304 hours
    Max time in space = 4 years = 1,461 days (3*365 + 1*366: leap year in 2008) = 35,064 hours

    2.1 billion miles / 26,304 hours = 79,835.77 mph
    2.1 billion miles / 35,064 hours = 59,890.49 mph

    So the average speed will be between 59,890.49 mph & 79,835.77 mph!! (or 96,384.16 kph & 128,482.90 kph)

    Considering the speed of sound (at sea level) is 761mph it's just as well in space nobody can here you play golf!
