WATCH: The real Gravity

With the movie Gravity premiering on DSTV101 tonight, 28 December 2014, for African Viewers, we thought it would be a good opportunity to highlight the real issue of Space Debris & the Kessler Syndrome:

OBJECTS IN SPACE 1957-2010

Kessler Syndrome
The Kessler syndrome (also called the Kessler effect, collisional cascading or ablation cascade), proposed by the NASA scientist Donald J. Kessler in 1978, is a scenario in which the density of objects in low Earth orbit (LEO) is high enough that collisions between objects could cause a cascade—each collision generating space debris which increases the likelihood of further collisions. One implication is that the distribution of debris in orbit could render space exploration, and even the use of satellites, unfeasible for many generations.
