Curiosity conquers a 30-degree slope on Mars for the first time, enjoys the view

Mars’s pluckiest rover, Curiosity, has made it up a steep, sandy slope to an area previously thought to be practically inaccessible and is enjoying the view.

For the past month, the rover has been wending its way up the path towards an area called the Greenheugh pediment. NASA researchers had wanted to explore this particular area for a long time, as it could hold clues to the geology of the surrounding crater, but they originally thought that it would be impossible to access it without months or even years of travel. However, they managed to identify a path that was accessible to the rover after consultation with surface properties scientists.

The route involved Curiosity climbing up slopes of 30 degrees or more, which is the steepest that the rover has ever attempted. While on its journey, Curiosity stopped to collect some data with its ChemCam instrument to investigate two bedrock targets, “Corriecravie” and “Shannochie”. By analyzing the rocks along the ascent to the Greenheugh pediment, the scientists can see how their composition changes with elevation.

Now, Curiosity has made it to the top of the slope and viewed an entirely new area of the Gale Crater. The rover is currently investigating two targets, “Galloway Hills,” which is a smooth, flat area of sandstone that needs to cleared of dust using the rover’s Dust Removal Tool before measurements are made, and “Ardwell Bay,” which is a more resistant rock than the surrounding sandstone.

With expansive views available from the Greenheugh pediment, we may have another high-resolution panorama of the Martian surface to look forward to. The Curiosity scientists have confirmed that they will soon be creating a stereo mosaic of the view using the rover’s high-definition Navcam which can capture images in color.

“Now that we do not have a steep cliff in our front windshield, the skies stretch largely unencumbered above and around us,” Curiosity scientists wrote in a blog post. “Navcam will take a 360-degree look around for dust devils on two different sols, and will acquire movies looking for clouds both in the afternoon and early morning. Mastcam and Navcam will assess the dustiness of the atmosphere by gazing across Gale crater from our great viewpoint.”

Curiosity spies a Martian ‘flower’ formed out of rock
Smaller than a penny, the flower-like rock artifact on the left was imaged by NASA's Curiosity Mars rover using its Mars Hand Lens Imager (MAHLI) camera on the end of its robotic arm. The image was taken on Feb. 24, 2022, the 3,396th Martian day, or sol, of the mission.

NASA's Curiosity rover, currently exploring Mars, has discovered an intriguing rock formation in the shape of a flower. The tiny object, smaller than a penny, was imaged by Curiosity's Mars Hand Lens Imager (MAHLI) camera which sits on the end of its robotic arm.

"Stop and small the Martian 'flower'," NASA wrote on Twitter. "On Feb. 24, 2022, our @MarsCuriosity rover captured this image of a flower-like rock. Smaller than a penny, this and a bouquet of other findings gives scientists insight into the Red Planet’s ancient past."

NASA’s Mars drone nails its first flight of 2022
NASA's Ingenuity helicopter.

Following several delays due to dust storms, NASA’s record-setting Ingenuity Mars helicopter has finally taken its first flight of 2022.

The 4-pound, 19-inch-tall rotorcraft flew at an altitude of 33 feet (10 meters) for almost 100 seconds and covered a distance of about 203 feet (62 meters) during its latest flight, the team at NASA’s Jet Propulsion Laboratory, which is overseeing the current Mars mission, confirmed on Tuesday.
