Up until recently, the limitations of camera technology made it a
huge challenge for the likes of NASA to record any detail in video shots
of rocket motor plumes, their awesome power and brightness resulting
in intensely brilliant footage that causes the rest of the image to
remain dark beyond recognition.
But that’s all changed with the arrival of the space agency’s new
High Dynamic Range Stereo X (HiDyRS-X) camera, a revolutionary prototype
device capable of capturing multiple exposures that combine to produce
remarkably detailed footage.
“Traditionally, video cameras record using one exposure at a time,
but HiDyRS-X records multiple, slow motion video exposures at once,
combining them into a high dynamic range video that perfectly exposes
all areas of the video image,” the space agency explains on its website.
The extremely detailed video provided by the new high-speed camera
significantly boosts NASA’s research capabilities, allowing it to view
not only the plume but also important components on the motor as it
fires.
The booster test shown in the video took place at Orbital ATK’s test facility in Promontory, Utah, a couple of months back.
It was the second and final booster test before NASA’s planned 2018
trial of the Space Launch System (SLS) heavy-lift rocket with the Orion
spacecraft.
SLS will be the most powerful rocket in the world when it goes into
operation and is set to help take astronauts further into space than
ever before.
Problems
The team charged with gathering the video footage only had one shot
at getting it right, as the booster couldn’t be turned off and restarted
if something went wrong with the camera equipment. And go wrong it did.
