NASA discovers mysterious blue dune on Mars

NASA discovers mysterious blue dune on Mars

This dune photograph was originally taken back at the end of January 2018, but NASA only just got around to releasing it - had the photo been taken recently, it would look blurrier due to the aforementioned dust storm which is now encircling the entire planet.

Along with this new comparison photo, NASA released an awesome animated image showing what Curiosity saw as the dust storm approached its current location. As the atmosphere warms, the winds generated by the temperature contrasts mobilize small dust particles that drift into the storm.

Lyot Crater on Mars also contains many classic barchan dunes. It seems that this haze is eight times thicker than normal, covering the planet in darkness, and making Curiosity rover's camera work more in the lack of proper lighting. The agency noted that the level of dust in the area where Curiosity operates, more than doubled over the weekend of June 16-17 alone. The dust storm is the largest since 2007 on Mars. According to Scott D. Guzewich, an atmospheric scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, if such conditions were to occur on Earth, it would be bigger than North America and Russian Federation combined.

Nigeria's Ahmed Musa challenges Lionel Messi as Argentina hero
Defensive pair Mercado and Otamendi suffered ankle injuries in the loss to Croatia but are expected to be fit to face Nigeria . However, Nigeria's inspiring 2-0 win over Iceland showed a tiny ray of hope amid dark-clouded criticisms to Argentina .

The images show a diverse, but apparently lifeless landscape. The camera has to take longer exposures when it takes photos. Unlike Opportunity, Curiosity is nuclear powered and doesn't require sunlight to function.

Last week, NASA disclosed that it lost contact with the "Oppy" rover, adding that the engineers do not expect to hear back from the robot until the skies begin to clear above it. It takes pictures regularly and sends stunningly colorful images of the surface of Mars to earth. While not crescent-shaped, this dune is made of a much finer material and has a different composition than the more standard barchan dunes surrounding it.

The colossal dust storm on Mars that has already enveloped the Curiosity rover is now a planet-wide event. Nowakowski reached out to SpaceFlight Insider in an effort to have the two space-related websites collaborate.
