While NASA’s InSight Mars mission is primarily focused on collecting data from the Red Planet’s interior, the lander recently trained one of its cameras on the Martian horizon, capturing a series of sunrise and sunset images.

NASA: Mega Dust Storms Could Have Blown Away Some of Mars’ Ancient Water

Giant dust storms on Mars, including the one that’put NASA’s Opportunity rover out of commission and blocked sunlight for weeks, may have blown away some of the Red Planet’s ancient water, according to NASA researchers.

Following the incident, scientists worldwide are analyzing insights on how mega dust storms could have impacted ancient Martian water, climate, and winds, and how they could affect future solar power and weather, said a NASA press release. Observations on the 2018 dust storm, which were published in Geophysical Research Letters, revealed key details on Mars’ water sources, including lakes, rivers, and oceans the planet had billions of years ago and why water might have disappeared there.

Water on Mars? NASA finds PROOF planet-sized dust storms ‘blew away’ Mars water into space

A new study published on April 10 by scientists in the journal Nature, has proposed giant dust storms could be to blame.

On Mars, giant dust storms are a regular occurrence, which kick-up enough dust into the skies for telescopes on Earth to see them.

The Martian storms range in size and intensity but can span the length of entire continents and last for weeks at a time.

Geronimo Villanueva, a planetary scientist at NASA’s Goddard Space Flight Center, believes storms like this are key to cracking the mystery of Mars’ missing water.

Monster Mars Dust Storms May Have Helped Blow Red Planet’s Water Away

But the storm didn’t just affect Opportunity’s digs near the Martian equator. NASA’s InSight lander views Martian sunrise, sunset ... NASA’s InSight Mars mission is primarily focused on collecting data from the Red Planet’s interior, the lander recently trained one of its cameras on the Martian horizon, capturing a series of sunrise and sunset images.. The sunrise shots were taken around 5:30 a.m. Mars local time on April 24, 2019, using the Instrument Deployment Camera on the end of the lander’s robotic arm. By June, the maelstrom had grown into a global monster, covering Mars with a pall of dust.

Such planet-wide storms aren’t terribly rare; NASA spacecraft also observed them in 1971, 1977 (twice), 1982, 1994, 2001 and 2007. (Opportunity and its twin, Spirit, managed to ride out the 2007 storm, but the one in 2018 was more powerful.) And these dramatic events, which highlight how dry and dusty Mars is today, may have helped the planet get that way, recent research suggests.

Things began to change when Mars lost its global magnetic field about 4 billion years ago. With this protective barrier gone, charged solar particles stripped away most of the planet’s atmosphere, and over time, Mars lost the ability to support liquid water on its surface.’
