Before NASA’s ‘InSight’ craft successfully landed on Mars in November, following its “seven minutes of terror,” the space agency had snapped an image of a sand dune on the Red Planet that appears blue, but in reality, has a grayish hue.
The eye-catching photo, shown above, shows a turquoise blue sand dune in enhanced color, a visual effect brought about by boosting the image’s contrast so researchers can make out more details.
This particular dune was found at Mars’ massive Lyot Crater, which is known for its patterned floor, and sits south of a group of barchan dunes. NASA’s Mars Reconnaissance Orbiter (MRO) originally took the image on 24 January 2018.
NASA explains on its website, “This particular dune, appearing like turquoise blue in enhanced color, is made of finer material and/or has a different composition than the surrounding.”
Recently, a mesmerizing ice-filled crater that resembles a huge skating rink was also discovered on the Red Planet.
Earlier this month, NASA’s ‘Voyager 2’ made headlines after entering interstellar space 41 years after its launch, a feat that the space agency celebrated by releasing a free new graphic poster inspired by the achievement. NASA’s ‘Parker Solar Probe’ also captured the first image ever taken from inside the sun’s atmosphere.
