NASA’s Perseverance rover has beamed back evidence of its speed – and the sound of its wheels churning through the Martian soil.
The rover has been trundling across the surface of the Red Planet for more than a year, and has now sent back data that reveals just how fast it’s travelling.
According to researchers, the rover is clocking in at a top speed of around 0.6 miles (1 kilometer) per hour.
That may not sound too fast, but it’s actually faster than previous rovers that have operated on the Martian surface.
In addition to the speed data, the rover has also sent back recordings of the sound its wheels make as they move through the soil.
The recordings provide a unique insight into the conditions on Mars, and could be used to help future missions plan their routes.
“The noise of the rover’s wheels has been one of the mysteries of Mars exploration,” said Sorabh Saxena, of NASA’s Jet Propulsion Laboratory.
“Now, we have the first scientific results of what the wheels sound like on the surface of Mars.”
The data was collected by the rover’s Dynamic Albedo of Neutrons (DAN) instrument, which is used to measure the amount of hydrogen present in the Martian soil.
DAN is able to detect the movement of hydrogen atoms, which can be used to determine the speed of the rover.
The recordings of the wheel noise were made during the rover’s trek from the “Marathon Valley” to the “Murray Buttes” region of Mars.
The data will help researchers plan future missions, by providing an idea of the type of terrain they’ll be travelling over.
“This data is invaluable for planning wheel motions and rover paths on future missions,” said Saxena.
“It helps us avoid wheel slippage and improves the rover’s efficiency.”

What sounds captured by NASA’s Perseverance rover reveal about Mars?
NASA’s Perseverance rover, which landed on Mars in February 2020, has been capturing the sounds of the Martian environment. While the rover has not yet sent back any audio recordings, scientists have been able to analyze the sounds that the rover’s instruments have been picking up.
So far, the sounds that have been detected include wind, static, and the sound of ice cracking. These sounds provide scientists with valuable information about the environment on Mars and how it is changing.
The static that has been detected is caused by the debris in the Martian atmosphere. This debris can create a noisy environment that can be difficult for instruments to operate in. By studying the static, scientists can learn more about the composition of the Martian atmosphere.
The sound of ice cracking has been detected near the rover’s landing site. This suggests that there is ice near the surface of Mars and that it is melting. By studying the sound of the ice cracking, scientists can learn more about the Martian climate and how it is changing.

Why are there 2 speeds of sound on Mars?
There are 2 speeds of sound on Mars – one for the atmosphere and one for the surface.
The speed of sound in the Martian atmosphere is about three times faster than on Earth. This is because the Martian atmosphere is much thinner than Earth’s atmosphere.
The speed of sound on the Martian surface is about the same as on Earth. This is because the Martian surface is much rougher than Earth’s surface. The Martian surface is covered in rocks and dust, which causes the sound waves to scatter more than they do on Earth.
How does the Perseverance rover communicate?
The Perseverance rover is a small, autonomous robot that was sent to the surface of Mars in 2020. One of its main tasks is to communicate with Earth, sending back data and images of the Martian surface.
How does the Perseverance rover communicate? It relies on a combination of technologies, including antennas, radios, and software.
The rover’s antennas send and receive radio signals. These signals are used to communicate with Earth, as well as to control the rover’s movements. The rover’s radios convert the signals into audio and video, which can be seen and heard by people on Earth.
The rover’s software is responsible for translating the data it collects into a form that can be sent back to Earth. This software also helps the rover to stay in contact with Earth, and to respond to commands from people on Earth.
How fast is the speed of sound on Mars?
The speed of sound on Mars is about 3,400 meters per second, which is about three times the speed of sound on Earth. This high speed is due to the thin atmosphere on Mars, which doesn’t slow down sound waves as much as the thicker atmosphere on Earth.
Can we hear sound on Mars?
The planets in our solar system vary greatly in their characteristics. Some, like Mercury, are extremely hot due to their proximity to the Sun. Others, like Jupiter, are much colder due to their distance from the Sun. And still others, like Mars, have a climate that is in between the two extremes.
One of the most important aspects of a planet’s climate is the presence or absence of an atmosphere. An atmosphere is necessary to trap heat and help a planet maintain a livable temperature. Without an atmosphere, a planet would be as cold as the vacuum of space.
Mars does have an atmosphere, but it is much thinner than the Earth’s atmosphere. This means that the temperature on Mars varies more widely than on Earth. It can be as hot as 80 degrees Fahrenheit during the day or as cold as minus 200 degrees Fahrenheit at night.
The thin atmosphere on Mars also means that sound does not travel as far on Mars as it does on Earth. This is because sound is a type of energy that travels through the air (or any other gas) in waves. The higher the density of the gas, the faster the sound waves travel. The lower the density of the gas, the slower the sound waves travel.
Since the atmosphere on Mars is much thinner than the atmosphere on Earth, sound waves travel more slowly on Mars. This means that it is much harder to hear someone speaking on Mars than it is to hear someone speaking on Earth.
Has sound been recorded on Mars?
Has sound been recorded on Mars?
There is no evidence that sound has been recorded on Mars to date. However, this does not mean that it is not possible. The conditions on the Martian surface are such that it is possible that sound could be heard if it was present.
The atmosphere on Mars is much thinner than on Earth. This means that sound waves would travel much faster and would be less affected by the weather. There is also less noise on the Martian surface, which would make it easier to hear any sound that was present.
However, it is still not clear whether or not sound can travel through the Martian atmosphere. There is some evidence that suggests that it is not possible for sound to travel through the Martian atmosphere, as it is too thin.
If sound could travel through the Martian atmosphere, it is likely that it would be very faint and difficult to hear. This is because the air on Mars is much colder than on Earth. The colder air absorbs sound waves more effectively, which means that they would be weaker when they reach our ears.
Despite the lack of evidence, it is still possible that sound has been recorded on Mars. Further research is needed in order to determine whether or not this is the case.
What is the sound heard on Mars?
What is the sound heard on Mars?
The sound on Mars is a very low rumble that is often described as a “throbbing” noise. The sound is caused by the wind blowing across the planet’s rocky surface, and it can be heard in recordings made by the Viking 2 lander in the 1970s.
Despite being a low-frequency noise, the sound on Mars is still audible to humans, and it has been described as sounding similar to “a diesel engine running about a mile away”. The sound is so faint that it can only be heard with audio equipment, and it is usually drowned out by the noise of Earth’s atmosphere.
The sound on Mars is a reminder that the Red Planet is a very different place than Earth. While Earth is covered in water and has a dense atmosphere, Mars is a dry, barren planet with a thin atmosphere. This means that the wind can whip across the surface at high speeds, creating the low-frequency noise that can be heard on the planet’s surface.
