Rover “Perseverance” sends audio recording of Mars voyage for the first time

Rover makes its first lap on Mars

The Mars rover “Perseverance” has made its first small lap and sent pictures from its excursion to earth. The NASA vehicle initially covered 6.50 meters. Longer stretches are to follow later.

The “Perseverance” rover drove 27 meters over Mars, producing a sound recording of around 16 minutes. The recording is already a few days old – and still a sensation.

Dhe rover “Perseverance” has sent an audio recording of a journey over Mars for the first time. It is the first recording of this kind, announced the US space agency Nasa on Thursday night. The approximately 16-minute sound recording was recorded by a microphone a few days ago during the rover’s approximately 27-meter journey.

“When you drive over stones with these bikes, it’s very loud,” said NASA engineer Vandi Verma. This is due, among other things, to the fact that the wheels of “Perseverance” (in German: stamina) are made of metal. “If I heard these noises in my car, I would stop and call the towing service,” added Nasa colleague Dave Gruel. “But when you think about what you’re listening to and where it’s recorded, it makes total sense.”

Previously, the rover had, among other things, sent sound recordings of its landing and trying out its laser to Earth.

“Perseverance”, weighing around 1,000 kilograms and the size of a small car, was touched down on February 18 after 203 days of flight with a risky maneuver in a dry lake on Mars. The rover will examine this lake with a diameter of around 45 kilometers over the next two years.

Development and construction of the approximately 2.5 billion dollars (about 2.2 billion euros) vehicle had taken eight years. Its mission is to search for traces of previous microbial life on Mars and to study the planet’s climate and geology.

Geyser on Europa, illustration. Europa is the smallest of the four Galilean moons of Jupiter, and the second closest to the planet. Its surface is icy and relatively smooth. Impacting meteorites cause melting of the surface, allowing the water to smooth out before refreezing. There is some evidence of large-scale movements of the ice, possibly supported by a liquid mantle and driven by thermal processes within the moon. Ice geysers have been seen on this moon, as in this illustration - jets of water-rich material spewing 200 km into space.
