The mysterious roar appears to come from a location on Mars called Cerberus Fossae.
REPUBLIKA.CO.ID, JAKARTA – Landing robot belonging to the American Space Agency (NASA) at Mars InSight managed to catch a mysterious roar coming from within the planet. Researchers believe the roar came from the sudden release of energy into the planet’s interior.
This rumbling sound was likely triggered by a tremor or “earthquake” that occurred on the planet. This phenomenon is known as a Marsquake or “earthquake” Mars, although the planet is believed not to have an active tectonic system like on Earth that can cause earthquakes.
The surface of Mars is more like the Moon which is much calmer when compared to Earth. However, the surface of Mars can experience vibrations due to cooling and contraction which then causes pressure.
According to NASA researchers, the mysterious roar appears to have come from a location on Mars called Cerberus Fossae. The previous Marsquake phenomenon is also believed to be centered at that location.
As reported Sky NewsPreviously, the Marsquake phenomenon occurred exactly one year of Mars time or about two years of Earth time. This previous Marsquake phenomenon occurred during the summer north of Mars.
Researchers believe that this summer could give InSight a better chance to hear the roar from Marsquake. The reason is, the wind on Mars is currently calmer.
Last year, NASA also shared votes thunder on Mars captured by InSight to the public. At that time, the roar also came from inside the planet, not from external factors outside the planet such as the wind.
“Mars, I can hear you. I detected a slow but different vibration on Mars. The faint rumbling appears to come from inside the planet and is still being researched by my team, try to listen,” wrote the account Twitter NASA InSight official last year.
In the upload, NASA InSight also uploaded a video sound recording captured by InSight. In the video, NASA InSight gives a difference in the rumbling sound caused by the wind, InSight robot hands, and a phenomenon that is suspected of being Marsquake.
Currently, the power in InSight is starting to decrease because Mars is moving away from the sun. InSight is expected to regain its energy injection in July when Mars begins moving closer to the sun again.
Before reaching July, various instruments on InSight will be temporarily turned off, including the seismometer. InSight’s seismometer, called the Seismic Experiment for Interior Structure (SEIS), is an instrument that plays a role in recording the phenomenon of rumbling and Marsquakes on Mars.
The research team hopes the seismometer on InSight can continue to burn for another month or two. After that, the seismometer will be temporarily turned off and InSight will go into hibernation.
