NASA releases first audio from Mars and video of landing of Mars Perseverance Rover
 |
NASA has released a new video from
NASA’s Mars 2020 Perseverance rover during its descent, and landing (EDL) on
the Red Planet on Feb. 18 as the spacecraft plummeted, parachuted, and rocketed
toward the surface of Mars. A microphone on the rover also has provided the
first audio recording of sounds from Mars.
The video covers the entire descent
process from the moment of parachute inflation, showing some of the rover’s
intense ride to Mars’ Jezero Crater. The footage from high-definition cameras
aboard the spacecraft starts 11 kilometres above the surface, showing the
supersonic deployment of the most massive parachute ever sent to another world,
and ends with the rover’s touchdown in the crater.
In addition, there was a microphone
attached to the rover, which did not collect usable data during the descent,
instead the commercial off-the-shelf device survived the highly dynamic descent
to the surface and obtained sounds from the Crater on Feb. 20. About 10 seconds
into the 60-second recording, a Martian breeze is audible for a few seconds, as
are mechanical sounds of the rover operating on the surface.
“This video of Perseverance’s
descent is the closest you can get to landing on Mars without putting on a
pressure suit,” said Thomas Zurbuchen, NASA associate administrator for
science. “It should become mandatory viewing for young women and men who not
only want to explore other worlds and build the spacecraft that will take them
there, but also want to be part of the diverse teams achieving all the audacious
goals in our future.”
“Now we finally have a front-row view to what we call ‘the seven minutes of terror’ while landing on Mars,” said Michael Watkins, director of NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission for the agency. “From the explosive opening of the parachute to the landing rockets’ plume sending dust and debris flying at touchdown, it’s absolutely awe-inspiring.”

NASA capturó imágenes emocionantes del aterrizaje de su rover en el cráter
Jezero de Marte el 18 de febrero de 2021. Las imágenes reales de este video
fueron capturadas por varias cámaras que forman parte de la suite de entrada,
descenso y aterrizaje del rover. Las vistas incluyen una cámara que mira hacia
abajo desde la etapa de descenso de la nave espacial (una especie de jet pack
propulsado por cohetes que ayuda a llevar el rover a su lugar de aterrizaje),
una cámara en el rover mirando hacia arriba en la etapa de descenso, una cámara
en la parte superior del vehículo. el aeroshell (una cápsula que protege el
rover) mirando hacia ese paracaídas, y una cámara en la parte inferior del
rover mirando hacia la superficie marciana. El audio incrustado en el video
proviene de las llamadas de control de la misión durante la entrada, el
descenso y el aterrizaje. Créditos: NASA / JPL-Caltech
