Another key feature of the spacecraft is that it would be equipped with a suite of cameras and a microphone that will be used to capture imagery and sounds of the entry, descent and landing sequence
- something that scientists have never before seen or heard.
During the emergency landing sequence
, the main rotor blades struck the tail boom, causing substantial damage.
If the landing sequence
works correctly, the probe sends a radio signal, and you can use that to pinpoint where it is coming from, even if it broadcasts only very briefly.
The entry, descent and landing sequence
for Beagle 2 worked and the lander did successfully touch down on Mars on Christmas Day 2003," UK Space Agency said in a statement.
Not only did this facility go on to produce the world's first computer animated films during the mid-seventies it also contributed the 3D wire-frame model shown on the navigation monitors in the landing sequence
of the Ridley Scott film 'Alien'--making it the Industrial Light and Magic or Weta computer animation facility of its day.
The landing sequence
appeared dis-jointed, leading some analysts to suspect that that portion of the video showed a smaller model touching down.
Engineers said the tricky landing sequence
, combining a giant parachute with a rocket-pack that lowered the rover to the Martian surface on a tether, allowed for zero margin for error.
Engineers designed Curiosity to begin its 7-minute landing sequence
when it reaches the atmosphere of Mars.
And being able to get that whole landing sequence
to work the way you did is a testimony to your team", he added.
Most of the data recorded by Curiosity's onboard inertial sensors has yet to be downlinked to Earth, but even the small fraction of information that is in the possession of engineers has allowed them to reconstruct the key moments of the landing sequence
Curiosity relied on VxWorks for the complex landing sequence
called EDL (entry, descent and landing).
Curiosity's intricate landing sequence
- dubbed "Seven Minutes of Terror" by NASA - set the rover down at 9:31 a.
