Gravity is a
beautiful and poetic movie. It is a technical marvel and one of the tensest 90
minutes of movie viewing I can recall. And it is about one of the little talked
about, but ever present, dangers of space travel and orbiting earth.
There are so many satellites floating around up there and
every now and then something comes apart, leaving space junk out there. This
space junk sometimes travels at mind-boggling speeds. If it comes into contact
with a shuttle or another satellite or an astronaut on a spacewalk, it could
have devastating consequences. The particular event in Gravity, directed and co-written by Alfonso Cuarón, along with his
son Jonás, is the destruction by missile of a Russian satellite. All those
little pieces of debris are orbiting at a speed of 20,000 kilometers per hour.
They rip through the space shuttle where mission commander Matt Kowalski
(George Clooney) and Dr. Ryan Stone (Sandra Bullock) are completing work on the
Hubble. The two are left stranded in space, their only remaining hope being the
escape pods on the International Space Station. And at the speed the debris is
traveling, they have about 90 minutes before they’re in for another shit storm.
