NASA’s InSight lander has provided the first ever “sounds” of Martian winds. The low-frequency rumbles were captured by the lander’s seismometer, which is designed to detect vibrations from the wind and from marsquakes.
The wind sounds are very low-pitched, and are only audible if you listen to them using headphones. They were recorded at a speed of around 10 mph (16 kph), and the lander’s team has estimated that the wind speeds on Mars are around 20 mph (32 kph) at the landing site.
The seismometer is also being used to measure the “marsquakes” that are thought to be caused by the movement of tectonic plates on the Martian surface. So far, the team has detected more than 600 of these quakes, and they are still analyzing the data in order to determine the precise cause of each quake.
The InSight lander was launched in May 2018, and it landed on Mars in November of that year. The seismometer was deployed in early February 2019, and the wind sounds were recorded a few weeks later. The lander’s team is still analyzing the data from the seismometer, and they will be releasing more information in the future.

What is the speed of sound on Mars?
Just like on Earth, the speed of sound on Mars depends on the atmospheric conditions. In general, the speed of sound is about three times faster on Mars than on Earth. This is because the Martian atmosphere is much thinner than Earth’s atmosphere.
What is the sound heard on Mars?
What is the sound heard on Mars?
There is no sound on Mars. This is because the planet has a thin atmosphere and no liquid water on the surface. Without either of these, sound cannot travel.
There may be some sound on Mars if you were to stand near an air vent or inside a spacecraft, but it would be very faint and difficult to hear.
Does Mars have two sound speeds?
Mars may have two different sound speeds, one close to the speed of sound on Earth and one much slower, according to a new study. If this is the case, it would be the first planet beyond Earth known to have multiple sound speeds.
The study, published in the journal Nature, used data from the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft to investigate the possibility of multiple sound speeds on Mars. MAVEN is a spacecraft that was launched in 2013 to study the Martian atmosphere.
The researchers found that the atmosphere on Mars is much thinner than the atmosphere on Earth. This means that the speed of sound is much slower on Mars than it is on Earth. They also found that the temperature of the atmosphere varies with altitude, which means that the speed of sound also varies with altitude.
The speed of sound is slower near the surface of Mars than it is higher up in the atmosphere. This means that there are two different sound speeds on Mars – one near the surface and one higher up in the atmosphere.
The researchers say that the two sound speeds on Mars could create a ‘sound barrier’ on the planet. A sound barrier is a barrier that blocks or slows the sound of objects travelling through the atmosphere.
The researchers say that the two sound speeds on Mars could cause problems for future missions to the planet. For example, they could cause problems for spacecraft that need to communicate with Earth. The two sound speeds could also cause problems for aircraft that fly on Mars.
The researchers say that more research is needed to determine the full effects of the two sound speeds on Mars.
How does the speed of sound on Mars compared to Earth?
The speed of sound on Mars is much slower than it is on Earth. This is due to the lower density of the Martian atmosphere. The speed of sound on Mars is about 1,600 meters per second, while it is about 340 meters per second on Earth. This difference in speed can cause problems for communications between Earth and Mars.
Has sound been recorded on Mars?
Has sound been recorded on Mars?
Yes, sound has been recorded on Mars. However, it is not possible to hear it with the human ear.
The sound was recorded by the InSight lander, which touched down on the Martian surface in November 2018. The lander’s seismometer has been detecting vibrations from the wind and from rocks moving around.
The seismometer is also able to record the sound of Martian quakes. These quakes are very weak, and so they are not audible to the human ear. However, they can be detected by the seismometer.
The sound of Martian quakes will help scientists to learn more about the interior of Mars.
Why is sound slower on Mars?
The speed of sound is affected by the medium through which it travels. In general, the speed of sound is slower in denser mediums. This is because the sound wave needs to push more atoms out of the way as it travels.
The density of the Martian atmosphere is about 1/5th the density of Earth’s atmosphere. This means that sound waves will travel about 5 times slower on Mars than they would on Earth.
This slower speed can make it difficult for people on Mars to communicate with people on Earth. The delay can be up to 20 seconds long, which can be frustrating for people trying to have a conversation.
What does Mars smell like?
There’s no definitive answer to this question since, as of yet, there hasn’t been a manned mission to Mars and therefore no one has had the opportunity to smell the planet firsthand. However, there are some theories out there as to what the Red Planet might smell like.
One idea is that Mars smells like gunpowder. This is because the Martian surface is covered in iron oxide, which is also known as rust. Rust has a very distinctive smell that is often described as being a bit like gunpowder.
Another possibility is that Mars smells like vinegar. This is because the Martian atmosphere is very thin and contains a high concentration of carbon dioxide. Carbon dioxide is also responsible for the planet’s reddish hue, and it is also what gives vinegar its sour smell.
Lastly, it’s been suggested that Mars smells like roasted almonds. This is because the Martian soil is rich in minerals like magnesium and calcium, which have a nutty aroma when roasted.
So, what does Mars smell like? There’s no definitive answer, but it’s likely that it has a range of different smells, depending on the composition of its atmosphere and soil.
