These Newly-Released Selfies From NASA's Mars InSight Lander Are Extremely Cool

InSight is designed to study the interior of Mars like never before using seismology instruments to detect quakes and a self-hammering mole to measure heat escape from the planet's crust

Scientists at NASA's Jet Propulsion Laboratory played recordings on Friday, December 7, of the sounds of Mars, captured by its new Mars lander, InSight, since it arrived on the planet late last month.

The noise is of the wind blowing against InSight's solar panels and the resulting vibration of the entire spacecraft. There is also an air pressure sensor on the spacecraft that recorded the air vibrations directly.

This is the only time when vibrations from the lander will be recorded by the seismometer, since it will be moved by the craft's robotic armed and placed on the Martian surface, along with other instruments.

The agency said that in next few weeks its Insight lander will also detect the effect of quakes or tremors on Mars, also called Marsquakes, which will provide a deeper insight into the the red planet's interior and possibly about the formation of planets including earth. These are the first sounds from Mars that are detectable by human ears, according to the researchers.

There are 3 audio clips that we heard.

BT to phase out Huawei Equipment deployed across its core 4G network
BT acquired telecoms firm EE in 2016 and will use its existing network to launch a national 5G rollout. There are also questions about how independent of state influence any large Chinese company can be.

"Capturing this audio was an unplanned treat", InSight principal investigator Bruce Banerdt said. In the near future, InSight will place the seismometer tool used to detect the vibrations on the planet's surface.

The Instrument Deployment Camera aboard NASA's InSight lander took this photo of one of the lander's 7-foot (2.2 meters) wide solar panels.

NASA designed InSight (a stationary science platform) to study tectonic activity and meteorite impacts on Mars. But InSight is not equipped with a microphone, rather, the sound was detected by sensors and a seismometer to measure sound waves.

The low-frequency sound resembles a "haunting low rumble", Nasa said. It's like InSight is cupping its ears. It will identify the various materials on Mars based on the change in sound frequency.

The air pressure sensor inside the shield will be relocated as well, and the team will gather data at night, when it expects the wind will have died down and the lander itself will be making less noise. "It just gives another way of thinking about how far away [we are when] we're getting these signals".
