Inspired by Mars landing, scientists to use Perseverance rover s navigation system to map Oceans on Earth
We know more about the Moon than we know about the oceans on Earth.

When the Perseverance rover hurtled down Mars s thin atmosphere towards the Jazero crater, a unique navigation technology helped guide it to a location that was most favourable for its survival during touchdown. This same technology is now going to be used to guide an autonomous vehicle to identify new features in the Atlantic Ocean.
WASHINGTON: Nasa’s Perseverance rover has for the first time captured the low-pitched whirring of the Ingenuity helicopter’s blades as it flies through the rarefied Martian atmosphere.
The space agency on Friday released new footage shot by the six-wheeled robot of its rotorcraft companion making its fourth flight on April 30 this time accompanied by an audio track.
The nearly three-minute-long video begins with the low rumble of the wind blowing across the Jezero Crater, where Perseverance landed in February on a mission to search for signs of ancient microbial life.
Ingenuity takes off, and its blades can be heard humming softly as they spin at nearly 2,400 rpm on the 872-foot roundtrip.

Nasa’s Jet Propulsion Laboratory in California released this first-ever audio that sounds like a low-pitched, far-away mosquito or other flying insect.
First came the amazing pictures, then the video. Now Nasa is sharing sounds of its little helicopter humming through the thin Martian air.
Nasa’s Jet Propulsion Laboratory in California released this first-ever audio on Friday, just before Ingenuity was set to soar on its fifth test flight. New sounds from Mars: Our @NASAPersevere rover caught the beats coming from our Ingenuity #MarsHelicopter! This marks the first time a spacecraft on another planet has recorded the sounds of a separate spacecraft.
First came the amazing pictures, then the video – and now Nasa is sharing sounds of its little helicopter humming through the thin Martian air.
Nasa’s Jet Propulsion Laboratory in California released this first-ever audio on Friday, just before Ingenuity was set to soar on its fifth test flight.
The low hum from the helicopter blades spinning at more than 2,500 revolutions per minute is barely audible. It almost sounds like a low-pitched, far-away mosquito or other flying insect.

That is because the 1.8-kilogram helicopter was more than 260 feet from the microphone on the Perseverance rover.
The rumbling wind gusts also obscured the chopper’s sound.
