Magnetic Movie by Semiconductor Films

This is one of my favorite films. Created In NASA’s Space Sciences Lab, it shows the chaotic life of magnetic fields. Very cool!

“The secret lives of invisible magnetic fields are revealed as chaotic ever-changing geometries . All action takes place around NASA’s Space Sciences Laboratories, UC Berkeley, to recordings of space scientists describing their discoveries . Actual VLF audio recordings control the evolution of the fields as they delve into our inaudible surroundings, revealing recurrent ‘whistlers’ produced by fleeting electrons . Are we observing a series of scientific experiments, the universe in flux, or a documentary of a fictional world?”

Nuclear Destroyer – NASA Mars Rover 2009

US aerospace titan Lockheed Martin announced yesterday that they had shipped the “backshell” for the Mars Science Laboratory (MSL) mission, the top half of the tin in which the rover will fly through space.

As the MSL descends from deep space into the thin atmosphere of Mars, the two-part aeroshell module will steer itself down by ejecting ballast to shift its centre of gravity. The backshell is mounted on a special-for-Mars ablative heat shield base made of cork and silicone, much of which will burn away from atmospheric friction as the spacecraft plunges down.
