"Gravity" had a the Hubble Space Telescope, the International Space Station, the Russian space station, which no longer exists, and a Chinese space station, fairly close to each other in space. This is very wrong. But I go to movies to be entertained, not to evaluate their scientific accuracy. Star Wars would be very boring without sound accompanying all the explosions. B.C.

The answer is yes. Should an asteroid be detected on a collision course, the public would be informed. As a matter of fact, you can see all known close approaches of asteroids by going to http://neo.jpl.nasa.gov/ca/ The protocol for such events is that NASA would inform the appropriate government agencies such as FEMA and the Dept. of Defense, who would coordinate a response. If time is short before an impact, that would probably consist of evacuating the area. B.C.

Meteorites contain basically the same elements as found on Earth, just in different abundances. So it is easier to get them here on Earth than wait for them to come to us. Exceptions may be iridium, which is more abundant in meteorites than on Earth, so if you're constructing an inter-dimensional portal like in the movie "Thor," you may have a need for such. B.C.

No one in recorded history has been killed by a meteorite, so I would say very small. A lady in Alabama was hit by a meteorite crashing through the roof of her bedroom in the 1950s. It bruised her side and she had to see her doctor, but no long term damage. B.C.

No, but that would sure make for an interesting day! (DM)
