Sound suppression system. Sites for launching large rockets are often equipped with a sound suppression system to absorb or deflect acoustic energy generated during a rocket launch. As engine exhaust gasses exceed the speed of sound, they collide with the ambient air and shockwaves are created, with noise levels approaching 200 db.
Noise control is an active or passive means of reducing sound emissions, often for personal comfort, environmental considerations, or legal compliance. Active noise control is sound reduction using a power source. Passive noise control is sound reduction by noise-isolating materials such as insulation, sound-absorbing tiles, or a muffler rather ...
Primary life support system. A primary (or portable or personal) life support system (or subsystem) ( PLSS ), is a device connected to an astronaut or cosmonaut's spacesuit, which allows extra-vehicular activity with maximum freedom, independent of a spacecraft's life support system. A PLSS is generally worn like a backpack.
Sure, some cameras can shoot haunting video lit only by the light of the moon, but for stills — and especially stills shot on a smartphone — digital noise continues to be a scourge.
Here’s something for all you space nuts out there. I happen to be in Naples, Florida visiting my parents and I was able to catch Space Shuttle Atlantis breaking the sound barrier just as it flew ...
Incredible footage released by Varda Space Industries gives us a first-person view of a space capsule’s return trip to Earth, from the moment it separates from its carrier satellite in orbit all ...
The Approach and Landing Tests were a series of sixteen taxi and flight trials of the prototype Space Shuttle Enterprise that took place between February and October 1977 to test the vehicle's flight characteristics. Of the sixteen taxi-tests and flights, eleven saw Enterprise remain mated to the Shuttle Carrier Aircraft (SCA), while the final ...
Artemis I is NASA’s moonshot mission to kickstart a new age of space exploration. Fifty-three years after humans first walked on the moon, NASA is kicking off its ambitious Artemis program to ...
