Ultraviolet light from Mars' aurora finds Emirati in orbit

The spacecraft orbiting Mars has captured the still-visible space light on the Red Planet.

The Emirati achieves expectationsArriving in early February, Mars saw the glow of the Aurora Boralis in the night sky. Amazing observations will help scientists to understand the atmosphere of Mars and how the red planet Aurora Boralis differs from similar light shows seen on Earth.

Northern Lights They occur when charged particles from space interact with atoms in the atmosphere and activate and glow. On Earth, it plays the role of northern and southern lights. When the sun’s particulate matter particles touch the planet’s magnetic field, they activate the upper atoms of the atmosphere, creating stunning images of green, purple, red, and blue light.

Aurora is different from Mars because it is believed that the red planet lost its global magnetic field billions of years ago, removing the once dense atmosphere of Mars in a nigo process.

“Instead we see magnetic fields that are a little special to Mars,” said Justin Deagan, a planetary scientist at the University of Colorado and deputy science head at the Hope Orbital Mission. “It originated from the minerals in the crust of Mars that formed in the early days of the Solar System. We thought Mars had a global magnetic field like Earth.”

Deagens added that the remnants of the magnetic field of Mars are mainly associated with these minerals scattered around the planet.

“Therefore, the charged particles will not be directed to the north and south poles, as are the places where the aurora borealis are seen on Earth,” he said. “They’re somewhere on Mars.”

This type of atmospheric light display, which is localized to specific magnetic fields, is called a discrete array.

Scientists want to study the aurora borealis on Mars, because they can not only discover the features of the planet’s atmosphere, but also solve other mysteries in the solar system.

“It raises these big questions about how planets interact with their stars,” Deagan said. “How does solar energy affect the upper atmosphere of the planets?”

Although Mars and Earth are two completely different worlds, what happens on the red planet may explain things closer to home.

“In Earth’s past, there have been events in which the global magnetic field has been diverted or weakened, so during these transitions the Earth was closer to Venus or Mars,” Deagens said. “In that sense, Mars can tell us things we can’t really learn right now.”

Special aurora borealis was observed in late April and early May with scientists UAE mission to explore Mars They tested the equipment on the Hope Probe. Launched into space in July 2020, the orbit is designed to study the atmosphere of Mars.

The arrows captured by ultraviolet light were the first major scientific discoveries of the UAE mission to Mars.

“The whole science team is on the upswing,” Degan said. “It was great to have had such a wonderful moment. It’s so much fun to see it so early.”
